The herbarium digitization process is an essential first step in transforming the vast amount of data associated with a physical specimen into flexible digital data formats. In this framework, the Herbarium of the University of Pisa (international code PI), at the end of 2018 started a process of digitization focusing on one of its most relevant collections: the Herbarium of Michele Guadagno (1878–1930). This scholar studied flora and vegetation of different areas of southern Italy, building a large herbarium including specimens collected by himself, plus many specimens obtained through exchanges with Italian and foreign botanists. The Herbarium is composed by 547 packages of vascular plants. Metadata were entered into the online database Virtual Herbaria JACQ and mirrored into a personalized virtual Herbarium of the Botanic Museum. After the completion of the digitization process, the number of sheets preserved in the Herbarium amounts to 44,345. Besides Guadagno, who collected 42% of his specimens, a further 1,102 collectors are represented. Most specimens were collected in Europe (91%), but all the continents are represented. As expected, Italy is the most represented country (59%), followed by France, Spain, Germany, and Greece. The specimens cover a time span of 99 years, from 1830 to 1929, whereas the specimens collected by Guadagno range between 1889 and 1928. Furthermore, we traced 134 herbarium sheets associated with documents, among which 75 drawings handmade by Guadagno, 34 letters from various corresponding authors, 16 copies of publications, and 14 copies of published iconographies.

This study focuses on Sternbergia lutea (L.) Ker Gawl. ex Spreng., a bulbous, perennial, autumnal flowering geophyte mainly distributed around the Mediterranean Basin. The seasonal content of total sugars, starch and proline in above- and below-ground plant parts in this study, which has hitherto not been the subject of a published study. Geophytes possess underground storage organs that support sprouting, leaf growth and flowering. Furthermore, their buds remain protected below the soil surface during periods of dormancy. Understanding the fluctuation of these compounds in S. lutea contributes to our knowledge of its adaptation to the Mediterranean ecosystem. It seems likely that monthly fluctuations in proline accumulation, sugar and starch content in both above- and below-ground tissues of S. lutea correspond to the distinct seasonality of the Mediterranean ecosystem. Elevated starch content was investigated in the bulbs, while lower starch content was estimated in the leaves. Substantial values of soluble sugar content have been detected in bulbs and leaves. Additionally, elevated sugar content was detected in the yellow petals of S. lutea in October. Pronounced proline accumulation was detected in the leaves and bulbs of S. lutea during its active and dormant phase, respectively. [ABSTRACT FROM AUTHOR]

Banana is a cash crop in Mediterranean Region of Türkiye, which is grown mainly in greenhouses and open fields. In weed flora surveys carried out in 2021 and 2022, an Eastern Asian plant, Cardamine occulta Hornem. (Brassicaceae), was determined first time in 60% of banana greenhouses in Türkiye. The species had been recorded in Europe in the second half of the 20th century, and then spread especially in urban areas of many European countries and Mediterranean Basin, which implies many habitats in Türkiye under the threat of C. occulta. The main diagnostic morphological features and an identification key are presented in comparison with those for allied C. flexuosa With. and C. hirsuta L. An eradication program is suggested because it is not scattered but limited with banana greenhouses in Türkiye. [ABSTRACT FROM AUTHOR]

Three sites in the southern Italian Apennines were selected to assess correlation between forest structure and bryophyte flora. In two of the sites, the Index of Air Purity (IAP)-based on cover data of epiphytic bryophytes-was evaluated. The results show that bryophyte populations-and consequently IAP-are affected by forest structure and development, and that studies including different sites require a precise assessment of silvicultural characteristics to allow comparisons. Indicator values of mosses and liverworts were also taken into consideration in characterizing ecologically the three sites. [ABSTRACT FROM AUTHOR]

Invasive macrophytes are considered problematic in natural environments and hydroelectric reservoirs. Climate changes, the occurrences of watercourses, and biotic interactions influence biological invasions of macrophytes. The abundance of native species can be positively or negatively correlated with the occurrences of invasives. Urochloa subquadripara is an invasive in natural or disturbed habitats co-occurring with the natives Eichhornia crassipes and Salvinia minima in South America. Aquatic plant communities can be altered by climate change, so species distribution models (SDMs) are important tools for predicting invaded areas. This study aimed to apply an SDM to study correlations of U. subquadripara with the potential distributions of native species E. crassipes and S. minima. Occurrence data for U. subquadripara, E. crassipes, and S. minima were collected from databases and in consultation with the published literature. Parameters encompassing biological information of the species were entered into the CLIMEX software and used to generate the Ecoclimatic Index (EI). The species co-occurrence was performed based on multicriteria decision-making (MCDM), and weights were assigned using the analytical hierarchy process (AHP). It was observed that U. subquadripara, E. crassipes, and S. minima had a higher occurrence in tropical and subtropical regions. However, it is predicted that these species may move to high latitudes from climatic changes. Considering climate changes, such as the increase in temperature and CO2, the risk of invasion by U. subquadripara in the northern hemisphere is mainly in lakes, whereas the areas conducive to invasions are rivers and reservoirs in the southern hemisphere. In general, emerging and floating macrophyte species such as U. subquadripara, E. crassipes, and S. minima will be favored, causing suppression of submerged species. Therefore, identifying the potential distribution of these species allows the creation of pre-invasion intervention strategies. [ABSTRACT FROM AUTHOR]

The response spectra defined in seismic design codes include crisp classifications of seismic parameters, which directly affect the spectra's shape and greatly alter seismic design loads. The optimum design phase seismic forces have an important role in the efficiency of the construction costs and structural safety. Various parameters are used to calculate the seismic design forces, especially presented in the codes with earthquake design spectra. This study presents a rule-based fuzzy inference model with fuzzy sets to determine these parameters using fuzzy inference system (FIS) modelling, which is the most appropriate approach among the different alternatives because both the input and output variables have numerical and linguistic uncertainties in the earthquake problem. Using the seismic zone factor of the region and shear wave velocity of the soil profile as inputs, the model generates the seismic coefficients and peak ground acceleration values of the response spectra specified in the Uniform Building Code (UBC, 1997). The response spectra in this code can be easily generated with these seismic coefficients after their fuzzification. Response spectra of twenty-five different sample cases with and without the FIS model are generated, which provide comparisons for the model superiority assessment. Significant differences are observed between the crisp logic and the FIS model-generated spectra. It is suggested that the FIS model can be modified and applied to various parameters to generate response spectra in different seismic design codes. [ABSTRACT FROM AUTHOR]

Cynodon dactylon (L.) Pers. is one of the worst agricultural weeds and invasive species in the world, being widely established in many countries. Despite its impact on agriculture and the growing awareness of authorities and consumers about the consequences of synthetic herbicides, alternative control methods for this weed have been poorly reviewed. A systematic review of the literature published over the last 50 years was used to assess the most studied control methods of C. dactylon (excluding synthetic herbicides) and to summarize the trends and knowledge gaps. The major findings are as follows: (1) the number of publications that studied alternative methods to synthetic chemical control in C. dactylon management has been increasing exponentially since 1972; (2) most of the studies were made under controlled conditions (57%) and lack observations under real production conditions; (3) most of the field experiments were carried out in Asia (42%), under temperate subtropical and arid climates; (4) the publication of articles studying allelopathy stands out significantly (50% of the papers found), with two species from the Poaceae family, rice (Oryza sativa L.) and sorghum (Sorghum bicolor (L.) Moench), showing very high allelopathic inhibitory effects (often above 80%), especially under open field conditions; and (5) preventive soil tillage is the most studied treatment among indirect weed control treatments, and although there is a high risk of propagation, the results indicate that tillage can significantly contribute to control C. dactylon, when compared to no-tillage treatments. Further research is needed to optimize treatments and methods so that they can be applied by farmers under real production conditions. [ABSTRACT FROM AUTHOR]

Cities are often hotspots for biological invasions, showing much higher percentages of alien species than non-urbanized settings. The reasons are multiple and are mostly related to two main factors: their heterogeneous, highly disturbed habitats and their many gateways that allow alien species introduction (e.g., airports, roads, train stations, or gardens). In addition to being a sink of biological invasions, cities can also be a source of the spread of alien species into surrounding landscapes, which adds further complexity to this issue. Herein, we are presenting the results of a five-year survey of the alien flora of Montjuïc, the largest urban hill in Barcelona (Spain). In just about 3.4 km2, we recorded up to 247 alien plant taxa, a figure much higher than those of many other Mediterranean cities and which clearly points to the role of Montjuïc as a hotspot for alien plants. The comparison with the alien flora of its surrounding region (coastal Catalonia) suggests that the alien flora of Montjuïc would have become enriched through many immigration episodes from close geographic areas. The hill, however, would have also acted as a source of the spread of alien plants, and indeed, some species have not been detected yet beyond the confines of Montjuïc. This study aims to be a key tool to ensure early detection and also to develop appropriate management and/or eradication actions. [ABSTRACT FROM AUTHOR]

The results of the annual excursion of the Working Group for Vegetation Science of the Italian Botanical Society, held in the Egadi Islands, Mount San Giuliano and Mount Cofano (W Sicily) on April 23--27 2022, are presented. This paper includes: (1) general information on the visited sites; (2) geology and geomorphology; (3) climatology and bioclimatology with tables of climatic data; (4) description of the following five geobotanical itineraries -- accompanied by 29 original vegetation relevés and 11 synthetic relevés, proceeding from different bibliographic references: (a) Mount San Giuliano; (b) Marettimo Island: coastal and subcoastal stretch of the southern part, between Punta Bassana and Contrada Chiappera; (c) Marettimo Island: Case Romane, Mount Pizzo Falcone and the north-western coastal stretch; (d) Island of Levanzo; (e) Mount Cofano -- with catenal pictograms of the vegetation, surveys and description of the plant communities and related syntaxonomic scheme; (5) list of the surveyed plant taxa, collected specimens and herbaria in which they are deposited. A new syntaxon is also described (Catapodio pauciflori-Moraeetum sisyrinchii ass. nova), referring to an ephemeral dry grassland located along the north-western coastal stretch of Marettimo. The new association is framed in the Plantagini-Catapodion balearici, alliance of the Stipo-Bupleuretalia semicompositi order of the class Stipo-Trachynietea distachyae (order Stipo-Bupleuretalia semicompositi, alliance Plantagini-Catapodion balearici). An original synoptic table, regarding 17 different plant communities with high frequency of Moraea sisyrinchium, provides a comparative framework of the new association with allied vegetation units so far described throughout the Mediterranean region. Syntaxonomical and nomenclatural remarks regarding the Mediterranean vegetation occurring in this territory are also given throughout the text. Some floristic updates for the study sites are also reported, including the discovery for the first time in Sicily of Lysimachia loeflingii. [ABSTRACT FROM AUTHOR]

The current paper presents the first effort to organize a comprehensive review of the Invasive Alien Species (IAS) of Greece. For this purpose, a database was developed with fields of information on the taxonomy, origin, ecology and pathways of introduction of terrestrial, freshwater and marine species. Our database includes a) taxa in the Union's list that are present in Greece, b) taxa already present in Greece and considered to be invasive, and c) taxa highly likely to enter Greece in the next 10 years and become invasive. The Database served as the starting point for the compilation of the National List of Alien Invasive Species (HELLAS-ALIENS) in compliance with the EU Regulation 1143/2014. Overall, the HELLAS-ALIENS comprises 126 species, i.e. 32 terrestrial and freshwater plant species, 14 terrestrial invertebrates, 28 terrestrial vertebrates, 30 freshwater fishes and invertebrates and 22 marine species. Terrestrial invertebrates, birds and mammals are mainly of Asiatic origin. Most of the terrestrial plants have their native geographical distribution in the Americas (North and South). Most of the freshwater invertebrates and fishes are of North American origin, while the majority of the marine species are of Indo-Pacific origin. The first records of IAS concern terrestrial plant species, and date back to the 19th century, while those in freshwater and marine ecosystems seem to have been systematically recorded some decades later. Regarding the pathways of introduction, most of the taxa arrived in Greece or are expected to arrive through escape from confinement and unaided. The majority of the terrestrial, freshwater and marine species have been evaluated as of High-risk for the indigenous biodiversity and only 3% of the species listed have been evaluated of Low-risk. Our results provide an important baseline for management and action plans, as required by the priorities set by the European Union through the Biodiversity Strategy for 2030. [ABSTRACT FROM AUTHOR]

The Greater Short-toed Lark Calandrella brachydactyla is a migrant bird, considered of conservation concern, but poorly studied in Italy about his breeding ecology and habitat use. In this work, we aimed to study both of these components in the airfield of Fano (Central Italy, Marches, Pesaro-Urbino province). The study, relating to the 2018-2022 reproductive seasons, describes the nesting habitat used by the species, providing also data about the plants on which the species feed on. We hypothsized the importance of the choice of fenced areas for the less predation and we highlighted the presences of young helpers in the feeding of the second brood. Furthermore, we observed the formation of crèches for the young fledglings, controlled by some adult males. It's confirmed here a semi-colonial condition that leading to the formation of extra-family groups before migration. The study area turns out to be the main reproductive colony of the species in the Marches region, with an average density of 1.5 pairs per 10 ha (maximum 2.4), one of the best know in central Italy.

Forest ecosystems are increasingly subject to disturbances, such as extreme (climate) events, fires and pathological outbreaks, which exert significant (and still poorly quantified) economic impacts, despite their intrinsic resilience. How forest management addresses these challenges will have profound effects on human health, environmental diversity, (ecological and economic) productivity and the ability of forest ecosystems to recovery from exogenous shocks. Assuming forests as ensuring ecosystem services that are vital to society and human well-being, in addition to providing wood material, a better knowledge of forest ecosystems appears a key requirement to delineate a developmental strategy that guarantees environmental protection objectives and achievement of climate and energy targets. In the context of Sustainable Development Goals of the United Nations 2030 Agenda, the information available on forest management practices in Europe still seems not completely suitable to provide a comprehensive overview of ecosystem conditions, their economic value, and their biodiversity. Based on a literature review, the present contribution focuses on recent dynamics of the forestry sector in Europe, delineating the inherent complexity in the environmental-economic nexus. Additionally, the extensive use of a key natural resource such as wood exerts social implications for local districts adapting to ecological change—from climate warming to landscape transformations. In line with earlier studies, our paper confirms the role of the technical-economic dimension of forestry in sustainable development paths of districts and regions, affecting together (i) short-term economic dynamics, (ii) the growth prospects of the sector, (iii) the organization of the supply chain, (iv) the interconnections between companies, and (v) investment strategies at large. One of the major issues is the low reliability of official statistics to provide a coherent picture of the actual status of forest resources. At the same time, forestry practices are pivotal in maintaining habitats and species while increasing the timber production that remains (too) sustainable. This is the policy direction constantly given by the European Commission to stimulate over time public bodies and private (in whose hands is about 60% of European forests) to start virtuous paths in the circular economy with considerable repercussions in terms of additional jobs, recycled materials, mt of CO2 equivalent avoided, and increase in community added value. In this context, forestry should assure a more 'holistic' contribution to sustainable development paths at various spatial scales. This means concentrating on both economic and environmental targets based on the identification of significant (ecological-economic) dimensions that may delineate future lines of investigation and policy intervention, while increasing between member countries and regional authorities.

Floral scents shape plant–pollinator interactions. Although populations of the same species can vary in their floral scent, little is known about how this variation affects pollinator visitation. In this study, we compare the scents emitted by buzz-pollinated Solanum rostratum (Solanaceae) in two areas of its distribution (Mexico and USA) and investigate how these differences in scent affect pollinator preferences and attraction. We determined the variation of floral volatile compounds using hexane extraction followed by gas chromatography coupled with spectrometry. We also performed a field cage multiple-choice bioassay and a Y-tube behavioural bioassay using Bombus impatiens. We recorded 13 volatile compounds in floral extracts for plants from both ranges that varied qualitative and semi-quantitatively among populations. We found that in the field cage experiment, bumble bees visited plants from the US populations more frequently than plants from Mexican populations. However, bees showed no difference in preference between extracts from Mexican or US flowers. We conclude that although bees show differential visitation to whole plants of different regions, variation in floral extract alone does not translate into differences in preference by B. impatiens. The potential effects of variation in floral scent on the other native bee pollinators remain to be assessed. [ABSTRACT FROM AUTHOR]

Biodiversity has become a priority in modern times. Over the past two centuries, the explosive development of human economy has led to the occupation of formerly natural areas for economic infrastructure or residential purposes. These replacements have resulted in the transformation of natural habitats into anthropized ones, disrupting the balance between species. Moreover, human activities have facilitated the migration of species from one continent to another, and the introduction of alien species to habitats different from their origin often has a significant impact on local biodiversity. This study aimed to investigate the incidence of alien species in three types of forest habitats (91E0*, 92A0 - riparian woods, and 9110 - beech forests) and three types of grassland habitats (6430 - Hydrophilous tall herb fringe communities of plain and of the montane to alpine, 6510 - lowland hay meadows, and R3803 - hillside hay meadows) within a set of protected natural areas in North-Western Romania (Central Europe). Out of the 23 species identified in habitats of community interest within the protected areas, 5 species are common to all of them. Among all the analysed habitat types, 91E0* riparian woods are the most affected due to human pressures, such as agricultural fragmentation, weakening of their structure, and the presence of road networks in their immediate vicinity. Beech forests, even though they have been mostly managed without considering their inclusion in Natura 2000 sites, show resistance to the spread of invasive alien species (IAS) due to their cohesive cenotic structure. For herbaceous vegetation, the pattern of IAS behaviour is similar - the most numerous and widespread IAS are found in narrow and ecotonal wet grasslands, while in well-connected, stable, and sustainably managed meadows, the incidence of IAS is minimal.

The inventory of the taxa collected during the annual field trip of the working group for Floristics, Systematics and Evolution of the Italian Botanical Society is reported. It was held in 2013 along the Maddalena Mountains, a mountain ridge of the southern Apennines located between the Basilicata and Campania administrative regions (southern Italy), considered as being poorly characterized in terms of vascular flora. A total of 701 units belonging to 74 plant families were recorded including two varieties and four hybrids. Thirty-five taxa resulted endemic to Italy and only 11 alien species were detected, while 36 taxa are new or confirmed for the regional floras of Basilicata and/or Campania. In particular, 12 taxa are new for Basilicata, while four are confirmed. Regarding Campania, 14 taxa resulted new for the regional flora and five were confirmed. [ABSTRACT FROM AUTHOR]

The 92/43/EEC Habitats Directive is the main European Union legal tool concerning nature conservation. The habitat types listed in Annex I to the Directive are phytosociology-based. It is widely acknowledged that phytosociological analysis is a crucial approach for habitats characterization and for monitoring their conservation status. Based on bibliographic investigations and new field survey campaigns, a list of habitat types neglected by the Habitats Directive is here presented and described for southern Italy. In this paper, 8 new habitat types and 13 subtypes are proposed. For each of these proposed new habitat types, a wide range of information, including ecology, chorology, species composition, syntaxonomy, threats, and conservation status, is here provided. To supply more detailed phytogeographical and coenological information about the proposed new habitat types, distribution maps based on 10 × 10 km reference grids and phytosociological tables including unpublished relevés were carried out.

A research was conducted in the Veneto region (NE-Italy) inside kitchen gardens and potato fields of outer pre-Alps, and in asparagus fields on the low Po plain near the Adriatic coast, in late summer-autumn after harvesting. Original vegetation-plot records were compared with historic and recent materials from Italy, especially N-Italy, and with comparable associations from Central and South-Eastern Europe, to ensure a consistent syntaxonomical frame of this highly dynamic vegetation. At the same time it was possible to shed light on the actual occurrence of past coenoses, cited by Italian authors for the Po plain. The analysis not only confirmed the occurrence of Echinochloo-Setarietum pumilae in north-eastern Italian territories, but also showed that it was more extensive than previously thought. It also confirmed the persistence of Panico-Polygonetum persicariae. The historical presence of Veronico-Lamietum hybridi occurring in pre-Alps and Dolomites needs confirmation. Further regional-scale investigations of summer crop weed vegetation appear necessary. [ABSTRACT FROM AUTHOR]

This paper presents palynological data obtained from a trench excavated at the Neolithic pile-dwelling archaeological site of Palù di Livenza (northeastern Italy). The site is in a wetland located in a tectonic basin at the foot of the Cansiglio plateau, crossed by the Livenza river. Environmental conditions have made this wetland a suitable area for settlements since prehistoric times. Thanks to the peaty sediments that characterise the area, archaeological materials and botanical remains have been exceptionally well preserved. Their study has shed light on a Neolithic pile-dwelling settlement that developed in various phases between c. 6350 and 5600 cal BP (c. 4400 and 3650 BC), and has also allowed for a detailed environmental reconstruction of the surrounding environment. A vertical sequence of 20 samples was analysed to study pollen, non-pollen palynomorphs and microcharcoals. An age-depth model was performed based on three radiocarbon dates. The palynological analysis provided insight into the response of vegetation to environmental changes caused by both climatic fluctuations and human pressure. In this sense, it was possible to highlight differences in vegetation cover, some fires, the use of woody resources, the spread of cereal fields, as well as the presence of other cultivated plants and plant processing by the people within the village.

Forests around the world are facing climate change. Increased drought stress and severe heat waves in recent decades have negatively impacted on forest health, making them more vulnerable and prone to dieback and mortality phenomena. Although the term vulnerability is used to indicate an increased susceptibility of forests to climate change with a worsening of their vigour status that can compromise their ability to respond to further climate extreme events, there are still uncertainties on how to evaluate it. Indeed, evaluation of forest vulnerability is complex both because of some critical issues in the estimation methods used and because of the multiple factors influencing the response of forests to ongoing climate change. A way to assess the vulnerability to environmental stresses is by combining remote sensing and dendroecological data. However, these two approaches entail multiple uncertainties, including growth/photosynthetic relationships, carbon allocation dynamics, biases of tree-ring data and noisy remote sensing data, which require further clarification for proper monitoring of pre- and post-drought forest trajectories. Our review aims to create an overview of the current literature and knowledge to understand the critical issues, needs and possible solutions that forest vulnerability research is addressing. We focus on Mediterranean forests located in a climate warming hotspot and showing a high vulnerability to increased aridification. [ABSTRACT FROM AUTHOR]

The division of alien species into groups according to the time of invasion is widely used in biogeographic and floristic studies, but such information is not available for many regions of Russia. On the basis of the analysis of regional floristic lists for the regions of European Russia (ER), 184 species of archaeophytes (that is, alien species intentionally or unintentionally introduced by humans in the early historical period, until the end of the 16th century) were identified. The age of their invasion was substantiated by a number of features (type of habitat, presence of fossil remains and historical evidence, geographical distribution, frequency of known cases of naturalization, identification of possible vectors of invasion, human use). Some species are archaeophytes only for a part of the ER regions; in neighboring areas, they can be either species of natural flora or alien neophytes according to their status. Eighty-one speciesoblast of putative archaeophytes are confirmed by archaeobotanical finds in any of the early histoblastorical periods, mainly in the Middle Ages, but from a limited number of regions. The territory of ER is divided into six regions taking into account the peculiarities of natural conditions, as well as the history of the development of anthropogenic communities: Karelian-Kola, East Baltic, Dvina-Upper Volga, Volga, Volga-Don, and Southeast. A more or less unified set of archaeophytes has been proposed for each of the major regions. The entire group of archaeophytes in ER as a whole is characterized by (1) the great similarity of the composition of archaeophytes with other European regions; (2) the low overall diversity compared to European countries, given the large area of ER; (3) the heterogeneous status of species in different regions and differences in the species composition between different parts of ER; (4) a large proportion of segetal weed species as a result of high infestation of crops with weed species at the beginning of the development of agriculture; and (5) a significant percentage of species of Asian origin as evidence of the influence of eastern vectors on the formation of flora, including the eastern centers of agriculture. Species essays are presented according to the above criteria for the species from the list of archaeophytes. [ABSTRACT FROM AUTHOR]

This paper proposes new anthropogenic pollen indicators for the Balearic Islands and attempts to assess gradients of human impact on vegetation in Mediterranean islands. A combination of modern pollen analogue studies, complemented by phytosociological descriptions and ordination techniques using quantitative and presence/absence data was used. Redundancy analysis allowed us to evaluate the relationships between pollen types and significant environmental variables and propose regional (e.g., Centaurea, Rubus, Plantago lanceolata-t) and local/microregional anthropogenic pollen indicators (e.g., Cerealia, Poygonum aviculare, Matricaria-t). Additionally, an anthropogenic index score (AIS) for each sampled location was calculated to correlate each pollen type to a specific degree of human impact: (a) low (e.g., Cerastium-t, Erica arborea-t, Cistus albidus), (b) moderate (e.g, Sinapis-t, Sanguisorba minor-t, Plantago bellardii-t), (c) high (e.g., Papaveraceae undiff., Dipsacaceae, Secale-t). This paper contributes to a further understanding of land-use dynamics and to defining the degree of impact, which is especially necessary to assess colonization and anthropization rhythms in Mediterranean island environments.

Lakes worldwide have been strongly affected by several types of human-caused alteration, including changes in water level. This also affects deep lakes, including volcanic ones. Volcanic lakes in the Mediterranean area are of great importance for the local economy, but local human activities can threaten their rich biodiversity. As a European biodiversity hotspot and habitat of endemic species, the volcanic Lake Bracciano (Central Italy) is an ecosystem of primary conservation interest threatened by sharply falling water levels, particularly since 2017. It also plays a key role in human wellbeing by providing important ecosystem services including drinking water, fisheries and various recreational opportunities. Although the lake has historically been considered to enjoy good ecological status, various environmental problems, often amplified by water level changes, have arisen during the last two decades. Given this recent rapid evolution, the lake can be considered an example of a valuable ecosystem at risk as a result of increasing anthropogenic pressures. The aim of this review is to examine the changes that have affected the lake in the last 20 years, considerably reducing its capacity to provide ecosystem services, and to review existing and potential threats in order to better inform the management of such resources.

This paper presents the results of a research performed on Gargano Promontory (SE-Italy) on the populations of Scabiosa garganica, a species with little herbarium records and whose few morphological descriptions are outdated. S. garganica belongs to the S. holosericea aggr., a group including very similar taxa that still have different taxonomic classifications. Its typical location is Monte Sant'Angelo in the Gargano area. Surveys have ascertained the existence of many populations, whose stational data help to understand the distribution and ecological conditions S. garganica is linked to. The morphological analysis of a large sample (75 plants from 9 sites) allows for the description of the qualitative and quantitative characteristics of this species. The new morphological framework highlights the species autonomy of S. garganica and can contribute to clarifying the relationship with S. holosericea and S. taygetea to which it is closer. In addition, for the correct delimitation of the species, the name Scabiosa garganica is lectotypified. Finally, the species was assessed against the IUCN criteria for the evaluation of its conservation status. [ABSTRACT FROM AUTHOR]

In this paper, based on fieldwork and herbaria surveys, new data concerning the presence of 32 native and alien vascular species for Sicily (Italy) are provided. Among the native species, the occurrence of the following taxa is reported for the first time or confirmed after many decades of non-observation: Aira multiculmis, Arum maculatum, Carex flacca subsp. flacca, Mentha longifolia, Oxybasis chenopodioides, Najas minor and Xiphion junceum. Furthermore, we document the presence of three native species (Cornus mas, Juncus foliosus and Limonium avei) that, despite being repeatedly observed in Sicily and reported in the literature, are inexplicably omitted by the most recent authoritative checklists regarding the flora of Italy. Finally, fifteen alien species new to Sicily (including one new to Europe, i.e., Pyrus betulifolia) are reported and seven poorly documented allochthonous taxa are confirmed for the island, and for two of them, a status change is proposed. These new or confirmed records allow us to better define the European and national distribution of the targeted taxa and offer new insights on the native and alien flora of Sicily.

Forest management is a complex topic at the interface between sustainability and the resilience of socioeconomic and environmental systems. The influence of market forces, supranational, country and regional policies, as well as climate change, on forest goods and services, is expected to increase in the near future. Such a complex interplay between economic and environmental forces is common to most European countries. The aim of this study is to operationally delineate and discuss the transition of the environmental sustainability and economic viability of forestry in Italy. This country encompasses the typical Mediterranean ecosystems with broad forest coverage in mountainous and hilly areas, where expanding woodland areas have been observed in the last decades mainly as a consequence of the decline of agropastoral activities, especially in disadvantaged and marginal areas. The consequent increase in wood biomass was frequently conceived as an element of environmental criticality, exposing woods to high vulnerability to wildfires and a consequent reduction in their economic value, possibly exacerbated by local warming. These dynamics usually took place in contexts where only a part of the overall forest heritage was subjected to regular management, despite the efforts made through various policies such as the Constitutional Law 3/2001 and the recent Law on Forests and Forestry Supply Chains. The latter policy tool, enhancing the concept of "active forest management" aimed to establish a sustainable approach to forest resources, leading to a broader forest area for formal planning and controlled harvesting. These dynamics took place in parallel with the inherent expansion in forest certification schemes formally promoting long-term environmental sustainability and a wider spectrum of forest ecosystems. Timber and non-wood materials and products are key elements from the perspective of achieving sustainable (climate-neutral) development in advanced economies. [ABSTRACT FROM AUTHOR]

The distribution and abundance of the various truffle species are influenced by the climate, soil, and vegetation conditions. The setting of these characteristics is necessary for the potential species' cultivation. Here, we describe the ecological characteristics of Moroccan truffles and desert truffles and their associations with host plants. We also determine the climate and soil parameters relating to the geographic distribution and fructification of truffles and desert truffles. In contrast to truffles, which are found in sub-humid environments, desert truffles are found in semi-arid and arid regions of Morocco. The dissemination of desert truffles in the Mamora forest and oriental regions of Morocco is typically linked to the presence of Helianthemum sp., whereas the existence of truffles (Tuber spp.) in the Middle Atlas depends on the subsistence of Quercus ilex and Q. faginea. The truffles' and desert truffles' fructification depends mainly on the precipitation frequency. Terfezia arenaria and Tuber oligospermum, the two major desert truffles of Mamora forest, require an annual rainfall of 435 mm on average in slightly acidic soil. While the oriental and Highland desert truffles, namely Terfezia boudieri, T. claveryi, and Tirmania spp., require an annual precipitation average of 123 to 267 mm and a high CaCO3 content. Otherwise, there is Tuber aestivum, localized in humid regions with a rainfall rate of more than 650 mm, and found under calcareous soil rich in organic matter with the presence of potential host plants, such as oaks, cedars, and pines. Our findings open up the possibility of successful cultivation of truffles and desert truffles having an economic interest through understanding their ecological requirements in Morocco.

Golden thistle (Scolymus hispanicus L.) is a wild edible plant belonging to Asteraceae family, with a great potential for food applications. The aim of this study was to identify the best cooking procedure able to provide a high-quality, ready-to-use product. For this purpose, leaf midribs (the most used edible part of the plant) were cooked by boiling, steaming, and 'sous vide', and the cooked products were compared for their phenolic content and composition, antioxidant activity, sugar and inorganic ion content, organoleptic characteristics, and microbial safety, this latter also during storage. In general, boiling caused a decrease in the value of these parameters, despite being the best product for taste and overall acceptability. On the contrary, steaming and 'sous vide' resulted in the best treatments to preserve antioxidant activity, total phenols, and chlorogenic acid. In particular, in 'sous vide' cooked samples, a significant increase in the value of these parameters and a remarkable decrease in nitrate content were found. Moreover, 'sous vide' resulted in the best treatment also regarding microbial safety during shelf life; actually, after 15 days of storage at 8 °C, Enterobacteriaceae and mesophilic aerobic bacteria were not detectable in 'sous vide' samples. These results contributed to increase the knowledge of a wild edible plant with high nutritional properties and promoting its consumption by obtaining a ready-to-use product with good organoleptic characteristics and endowed with a long period of shelf life.

Invasive alien species represent one of the main environmental threats to native biodiversity and can also strongly alter the biogeochemical cycles within an ecosystem. This study aims to define the distribution of the invasive alien species Cotula coronopifolia L. within the protected wetland "Variconi" (Campania region, southern Italy) and evaluate the potential role of water geochemical features as interpretation tools for pattern distribution. The presence of C. coronopifolia was assessed in the field, and a distribution map was drawn; concomitantly thirty-nine water samples were collected from groundwater and surface water bodies for chemical analyses. The results showed that C. coronopifolia preferentially colonized the sector of the wetland characterized by high halinity, while it is totally absent in retrodunal and sandy coastal area with very high halinity. The cartography presented can be used as a tool to help target future management interventions. Through our multidisciplinary approach, new evidence has been provided on the ecology of this invasive alien plant that occupies several wetlands worldwide. The replicability of this method may be useful to assess the level of invasion of an alien species but also to predict its evolution as a function of environmental parameters. [ABSTRACT FROM AUTHOR]

Ecological variables may be expressed on four basic measurement scales (nominal, ordinal, interval or ratio), whereas circular variables and those combining a nominal state with other scale types are also common. However, existing methods are not suited to calculate correlations between all pairwise combinations of such variables, preventing the application of standard multivariate techniques.The essence of the new approach is to derive a so‐called difference semimatrix for all pairs of observations for each variable, and then to calculate the matrix correlation based on two such semimatrices. The advantage of this function, termed d‐correlation, is that comparisons are made on the same logical basis regardless of the measurement scale, allowing for the use of principal components analysis to visualize interrelationships among many variables simultaneously. Further advantages are that missing values in the data are tolerated and that the Gower index of dissimilarity between objects may also be computed.The use of the method is demonstrated on a small toy matrix, an artificial plant trait matrix and a large dataset summarizing ecological features of all vascular plant species of Sardinia, Italy. The source code in R and FORTRAN, and applications for three different operation systems, are provided for computations with results serving as input for other statistical software.The new computational framework will allow the comparison of any types of ecological traits in a mathematically meaningful manner. This option was not available earlier in the field of multivariate statistics, and the method is expected to receive applications in other subject areas as well in which many objects are described in terms of variables expressed on different measurement scales.

Simple Summary: To find alternatives to common ingredients, possibly of local origin, is very important considering the most recent global crisis. Rice bran could be a valuable candidate for poultry diets, but its chemical–nutritional characteristics and the effects on living birds must be carefully evaluated to identify all the possible negative or positive effects. In addition, the use of supplements in combination with rice bran in poultry diets can be a solution to recover some negative effects of this ingredient. The impact of dietary rice bran with or without feed additives on the performance, carcasses, and blood profiles of chickens was examined. A total of 245 unsexed one-week-old broiler chicks were divided into seven groups, with seven replications of five chicks each. The treatments were: (1) control, (2) 5% rice bran, (3) 5% rice bran + 0.5 g/kg of Liposorb®, (4) 5% rice bran + 1 g/kg of vitamin E-Se, (5) 10% rice bran, (6) 10% rice bran + 0.5 g/kg Liposorb®, and (7) 10% rice bran + 1 g/kg of vitamin E–selenium. Considering the entire experimental period, it did not affect the in vivo performance of the broilers. However, all the experimental diets decreased dressing % compared with the control (p < 0.01) and the worst values were obtained for the 10% RB groups (75.7, 75.9, and 75.8%, respectively, for 10%RB, 10%RB + Liposorb, and 10%RB + Vit. E-Se groups). All the experimental diets decreased (p < 0.01) the albumin/globulin ratio due to an increased level of serum globulins. Differences in lipid profiles, antioxidants, and immunity parameters in plasma were not related to dietary treatments. In conclusion, the use of rice bran up to 10% in diets had no harmful effect on the overall growth performance of the broilers from 1 to 5 weeks of age. Still, carcass characteristics were negatively affected, except for heart percentage. In addition, the supplementation of Liposorb® or vitamin E-Se to rice bran diets did not recover these harmful effects. Thus, rice bran could be utilized at 10% in broiler diets when growth performance was considered; further research is required. [ABSTRACT FROM AUTHOR]

Obesity is a highly prevalent disease in dogs and is characterized by the excessive accumulation of adipose tissue that results in metabolic changes. Its treatment is based on a negative energy balance focusing on energy restriction. However, there are few studies in dogs that assessed the energy intake needed for adequate weight loss and to weight maintenance afterward. The aim of this study was to evaluate data about the treatment of canine obesity, with emphasis on energy restriction to induce weight loss and to maintain body weight (BW) and ideal body condition after weight loss. This was a retrospective study in which records of obese dogs from a veterinary teaching hospital were assessed between 2014 and 2020. Sixteen dogs were considered in the study according to inclusion and exclusion criteria and 10 of these participated in the maintenance phase after weight loss. The animals lost a mean of 23.2% their initial weight in a mean of 422 days. The mean weekly weight loss rate was 0.58% of BW, and the mean daily energy intake for weight loss was 59 kcal/kg current BW 0.75 . When the target BW was considered, which was defined as the current weight minus 10% for every point in the body condition score scale above 5, the mean energy for weight loss was 71 kcal/kg target BW 0.75 . In the maintenance phase, the animals were assessed for a mean of 134 days. The mean energy intake to maintenance BW was 70 kcal/kg BW 0.75 . The lower energy requirement of obese dogs during and after weight loss can work as an alert for the formulations of therapeutic weight loss diets to contain a high nutrient density focusing on the wellbeing, health, and quality of life of obese dogs, not just for the weight loss phase, but a diet for the weight maintenance phase., (© 2024 Wiley‐VCH GmbH.

The Linnaean name Crepis foetida is lectotypified with an illustration from the third volume of Morison's Plantarum historiae universalis Oxoniensis. While the designated lectotype can be identified with C. foetida s.l., it cannot be ascribed with certainty to any of the currently accepted subspecies of this taxon and is therefore considered demonstrably ambiguous.

Structural damage detection using unsupervised learning methods has been a trending topic in the structural health monitoring (SHM) research community during the past decades. In the context of SHM, unsupervised learning methods rely only on data acquired from intact structures for training the statistical models. Consequently, they are often seen as more practical than their supervised counterpart in implementing an early-warning damage detection system in civil structures. In this article, we review publications on data-driven structural health monitoring from the last decade that relies on unsupervised learning methods with a focus on real-world application and practicality. Novelty detection using vibration data is by far the most common approach for unsupervised learning SHM and is, therefore, given more attention in this article. Following a brief introduction, we present the state-of-the-art studies in unsupervised-learning SHM, categorized by the types of used machine-learning methods. We then examine the benchmarks that are commonly used to validate unsupervised-learning SHM methods. We also discuss the main challenges and limitations in the existing literature that make it difficult to translate SHM methods from research to practical applications. Accordingly, we outline the current knowledge gaps and provide recommendations for future directions to assist researchers in developing more reliable SHM methods. [ABSTRACT FROM AUTHOR]

We analysed the invasion history of two North American macrophytes (Elodea canadensis and E. nuttallii) in Italy, through an accurate census of all available herbarium and field records, dating between 1850 and 2019, and a rich literature collection describing the initial introduction and naturalisation phase that supports the results obtained by the occurrence records. Elodea canadensis arrived in Italy before 1866 and had two invasion phases, between the 1890s and 1920s and between the 1990s and 2000s; E. nuttallii, probably arrived in the 1970s, started invading in 2000 and the invasion is still ongoing. Botanical gardens and fish farming played a crucial role in dispersal and naturalisation of both species. The current invasion range of both species is centred in northern Italy, with scattered occurrences of E. canadensis in central and southern regions. River Po represents a dispersal barrier to the Mediterranean region and a strategic monitoring site to prevent the invasion in the peninsula. The study detects differences in the niches of the two species during the introduction and naturalisation phase and a habitat switch occurred after 1980 in E. canadensis and after 2000 in E. nuttallii, during their expansion phases. For E. canadensis the switch corresponds to the second invasion round. Further research can clarify whether the second invasion round is due to confusion of the recently introduced E. nuttallii with E. canadensis, to a cryptic introduction of a new genotype, to post-introduction evolution, or just to an increased scientific interest in biological invasions.

Since 1987 when dry-point-contact (DPC) transducers were invented in the USSR, ultrasonic shear wave devices based on those transducers have been commercialized and have become one of the most effective technologies for imaging concrete. That said, the objectives of this paper are (1) to provide a brief review of the historical development of these powerful devices and (2) to provide a comprehensive assessment of their capabilities in imaging internal entities and structural defects. Regarding the former, the paper presents the context that gave birth to DPC technology and different generations of ultrasonic shear wave devices for concrete inspection. For the latter, one of the state-of-the-art ultrasonic shear wave devices (MIRA 3D) was used to collect data on concrete specimens with different built-in flaws/defects. Those data are then visualized with a commonly used data processing algorithm, the so-called synthetic aperture focusing technique (SAFT). Finally, based on the resulting images, the capabilities of the device are discussed in detail for each concrete imaging problem. A main limitation of ultrasonic shear wave technique for concrete inspection is that it requires a significant amount of time and effort for data collection. [ABSTRACT FROM AUTHOR]

Oenothera jamesii Torrey & A. Gray (Onagraceae), a native of the southwestern United States and adjacent parts of Mexico, was found along a streamside near Aksu village in Çağlayancerit and along roadsides in Andırın district of Kahramanmaraş Province in the Eastern Mediterranean Region of Turkey. It is the fourth Oenothera species noted so far in Turkey. This species is morphologically similar to Oenothera biennis Linnaeus and O. stucchii Soldano. It is distinguishable from other Oenothera species in Turkey by the following combination of characters: stem very long (up to 2 m) and erect, petals yellow and 40–50 mm in length, and very long hypanthia of (6–)8–12(–16) cm in length. A full botanical description, seed surface sculpture in SEM, habitat features, field photographs and a distribution map are provided, as well as an identification key to the genus Oenothera in Turkey.

Defects are essential indicators to gauge the structural integrity and safety of reinforced concrete bridges. Non-destructive inspection has been pervasively explored over the last three decades to localize and characterize surface and subsurface anomalies in reinforced concrete bridges. In addition, different fuzzy set theory-based, computer vision and artificial intelligence algorithms were leveraged to analyze the data garnered from non-destructive evaluation techniques. In light of the foregoing, this research paper presents a mixed review method that encompasses both bibliometric and systematic analyses of the state-of-the-art work pertinent to the assessment of reinforced concrete bridge defects using non-destructive techniques (CBD_NDT). In this context, this study reviews the literature of journal articles and book chapters indexed in Scopus and Web of Science databases from 1991 to the end of September 2022. To this end, 505 core peer-reviewed journal articles and book chapters are compiled for evaluation after conducting forward and backward snowballing alongside removing irrelevant papers. This research study then exploits both VOSVIEWER and Bibiometrix R Package for the purpose of network visualization and scientometric mapping of the appended research studies. Thereafter, this paper carries out a multifaceted systematic review analysis of the identified literature covering tackled bridge defects, used non-destructive techniques, data processing methods, public datasets, key findings and future research directions. The present study is expected to assist practitioners and policymakers to conceive and synthesize existing research and development bodies, and future trends in the domain of the assessment of bridge defects using non-destructive techniques. It can also aid in raising awareness of the importance of defect management in bridge maintenance systems. [ABSTRACT FROM AUTHOR]

Two species of the Calcarata species complex of Viola section Melanium have been hypothesized to be of polyploid hybrid origin. To test this hypothesis, we used a modified restriction site associated (RAD) DNA-sequencing approach along with ITS and plastid DNA sequence data for reconstructing and dating the phylogeny of the group. For the detection of polyploid hybrid speciation and the parental lineages involved we used the four-taxon D -statistic metric (ABBA-BABA). Viola corsica (Elba, Corsica, Sardinia; calcifuge) and V. tineorum (Sicily; calcicole) were confirmed as polyploid hybrid species. They share V. cassinensis subsp. cassinensis (central Apennine; calcicole) as a parental lineage with V. bertolonii (Maritime Alps; serpentine) as the second parent of V. corsica and with V. nebrodensis (Sicily; calcicole) as the second parent of V. tineorum. The geographical distribution of the two hybrid species reflects the geographical distribution of the differential parent lineages. Substrate requirements of V. corsica are different, and those of V. tineorum are identical to those of their respective parents. We conclude that the differential distribution and ecology of V. corsica and V. tineorum can be traced back to properties of their respective parents. [ABSTRACT FROM AUTHOR]

The morphological characteristics, phytochemical composition of Pimpinella anisoides fruits was investigated. The morphological analysis of the monocarps contributed to distinguish P. anisoides from other related Pimpinella species used for commercial purposes, in particular P. anisetum and P. anisum. Our study showed that these fruits are different for their surface and shape: in particular, P. anisoides monocarps are glabrous, whereas the other two species are strigose. Two main compounds were identified in the essential oil of the five studied accessions: limonene (46.78-50.74%) and anethole (38.50-42.77%) whose sum ranged between 85.28 and 93.51%. estragole and β-phellandrene were other two representative compounds. All other volatiles accounted for less than 1% of the total volatile composition. One-way ANOVA analysis showed significant differences in almost all volatiles, whereas non-significant differences were found in the compounds detected in very low quantity. Hierarchical cluster analysis allowed to group the five accessions in three main clusters. Principal Component Analysis (PCA) showed that the first two principal components explained 71.80% of total variance. Results show that morphological and phytochemical features of the ripe fruits of P. anisoides can be used to distinguish this species from others, to avoid commercial sophistications and for a better conservation.

Vegetation diversity and ecology of grassland communities with Salvia officinalis were assessed in the natural range of the species in the Western Balkans, using the Braun-Blanquet approach. With the aim of defining the differences among the communities and identifying the main environmental gradients, cluster analysis (Flexible Beta method) and non-metric multidimensional scaling ordination were applied. From a total of 346 phytosociological relevés (259 relevés were used from the literature, and 87 new relevés were collected recently in Montenegro and the Middle Dalmatian Islands of Croatia), seventeen associations were identified. Three associations (Brachypodio retusi-Salvietum officinalis, Salvietum brachyodonti-officinalis and Salvio officinalis-Phlomidetum fruticosae) and one subassociation (Stipo-Salvietum officinalis campanuletosum lingulatae) were described for the first time. Most of the associations belong to the alliances Saturejion subspicatae and Chrysopogono grylli-Koelerion splendentis, separated along an altitudinal and thermal gradient. They were classified in the order Koelerietalia splendentis and in the class Helianthemo cani-Seslerietea nitidae, whose presence in the western Balkans is a syntaxonomic novelty. Three associations belong to three other vegetation classes, Festuco-Brometea erecti, Lygeo sparti-Stipetea tenacissimae and Ononido-Rosmarinetea. [ABSTRACT FROM AUTHOR]

The Mediterranean basin is rich in wild edible species which have been used for food and medicinal purposes by humans throughout the centuries. Many of these species can be found near coastal areas and usually grow under saline conditions, while others can adapt in various harsh conditions including high salinity. Many of these species have a long history of gathering from the wild as a source of food. The aim of this contribution is an overview on the most important halophyte species (Salicornia sp. pl., Arthrocaulon macrostachyum (Moric.) Piirainen & G. Kadereit, Soda inermis Fourr., Cakile maritima Scop., Crithmum maritimum L., Reichardia picroides (L.) Roth., Silene vulgaris (Moench) Garcke subsp. tenoreana (Colla) Soldano & F. Conti, Allium commutatum Guss., Beta vulgaris L. subsp. maritima (L.) Arcang., Capparis spinosa L.) that traditionally have been gathered by rural communities in southern Italy, with special interest on their ecology and distribution, traditional uses, medicinal properties, marketing and early attempts of cultivation. It is worth noting that these species have an attractive new cash crop for marsh marginal lands. [ABSTRACT FROM AUTHOR]

The aim of this study was to deepen our knowledge on the heritage and traditional uses of some medicinal plants of the Cilento, Vallo di Diano and Alburni National Park (Salerno province) and to evaluate their productive potential, in order to increase possible uses to recover and enhance the territory. Biometric surveys and biomass evaluation were carried out. Two types of aqueous extract were prepared using air-dried samples of six harvested species and tested for anti-germination activity on Lepidium sativum L. Hydrolates were recovered via steam distillation from aromatic species and the chemical–physical characteristics were determined. Historical evidence of industrial activity was collected in the territory of Sanza on Monte Cervati, where lavender essential oil has been distilled in the past century, and characterization of the essential oil components was carried out. The ethnobotanical uses detected mainly concerned traditional medicine and nutritional, ritual, or religious uses. The experimental results highlight that spontaneous medicinal plants could become potential sources of local economic development, with uses not only in the phytotherapeutic sector, but also in others, such as food and agriculture for weed control. Moreover, the evidence derived from industrial archeology could represent a further driving force for the enhancement of the territory's resources. [ABSTRACT FROM AUTHOR]

A new species of Solenopsis (Campanulaceae), S. bacchettae from Sardinia (Italy) is described and illustrated. Previously, it was misidentified as S. bivonae, due to its habit and corolla shape, but several relevant morphological features allow to distinguish it from the latter. Its morphology, seed coat and pollen micromorphology, ecology, distribution, conservation status and taxonomic relationships are presented. [ABSTRACT FROM AUTHOR]
