The insects trapped in 63 plots positioned in a mixed pinewood and a marsh in Schinias, Marathon, Greece is studied relative to the anthropogenic disturbance. The last anthropogenic impact was recently intensified because of the Olympic Games in the area. One hundred and forty insect species were found that had abundances greater than two individuals in each sampling session in all plots. Seven insect community types were found using cluster analysis. The types, which corresponded to recognized habitats, re-emerged in a non-metric multidimensional scaling ordination. It was also found that insects tended to dwell in different plots, even in the same habitat. The invading P. halepensis Mill., which replaces P. pinea L., changed the entomofauna. The seven habitats had different numbers of bioindicators out of 74 insect species, not in general correlated with human impact. Three components of insect diversity were measured, and the temporal species turnover was consistently higher than the spatial one. In this sense, pine habitats were rated first in terms of overall insect diversity. In terms of biodiversity, the impact on the various biotopes was assessed utilizing the diversity–equitability index V, which indicated that the two P. halepensis-dominated habitats have negative V values together with the habitat dominated by Tamarix hampeana Nied. The conservation of P. pinea and the marsh habitats is recommended for conserving local entomofauna and stopping the progression of P. halepensis. The optimization of management strategies to meet the management goals of all elements of this degraded ecosystem seems to be crucial. [ABSTRACT FROM AUTHOR]

Fungi are among the most important organisms on earth, and they are essential components of terrestrial ecosystems. Their reproductive structures are strictly dependent and affected by environmental conditions, and community dynamics over time and space may be indirect indicators of the health status of forests. We combined macrofungal biodiversity indices in eight Mediterranean forests in Italy and surveyed 160 plots by standardized surveys, to evaluate the role of macrofungi as early predictors of change in the forest structure. The results show that indices of fungal diversity are influenced by geographic and floristic conditions, and inter- and intra-annual temperature and rainfall fluctuations affect the formation of fungal fruiting bodies. These findings suggest that environmental changes could be reflected by macrofungi, and conservation initiatives should consider the pivotal role that fungi play in biodiversity monitoring.

Biodiversity ,580 Plants (Botany) - Abstract
This review of trends in inland saline lakes of Europe and Central Asia is based on the relevant section of the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) Regional Assessment Report for Europe and Central Asia (ECA). We assessed the present status of ECA saline lakes and the effects of direct drivers (climate change, land use, pollution, resource exploitation, invasive species) on ecosystem health and biodiversity. We also assessed past, current and future trends using habitat area and degradation, species richness, and endangered species as indicators. No uniform scenario is applicable to saline lakes in the region. The desiccation of the Aral Sea is caused mainly by land use change and water extraction. In the Caspian Sea, river modifications, water pollution, overfishing and poaching, and species invasions have led to a decrease in species richness and have threatened endemic species. Although trends for smaller saline lakes vary, our analysis demonstrates that land use change, over- exploitation, and pollution are more important direct drivers of ecosystem health and biodiversity than climate change. The establishment of baseline biodiversity values for saline lakes is, however, complicated because biodiversity and the food-web structure are variable and depend strongly on salinity. Thus, there is a need to classify the ecological quality, biodiversity and ecosystem services of saline lakes along a salinity gradient. The improvement of water management and reuse of water, conservation measures, and introduction of climate-smart agriculture are basic conditions for the sustainable use of saline lakes in the region.

Macrofungi are among the most crucial ecological forest resources and essential components of terrestrial ecosystems. Despite growing socio-economic interest, knowledge of their production is not understood because of many factors that can affect their natural growth. The aim of this study is to analyze which biotic and abiotic factors can influence the diversity and biomass of macrofungal fruiting bodies, at small and large scales. We worked in broadleaf Mediterranean forests, with a special focus on wild edible species (Porcini). The mycological observations were focused on epigeous macrofungi. To investigate connections between the occurrence of Boletus edulis species distribution modeling was used. Contrary to previous studies, the results reveal that, at a small (local) scale, the soil properties and the geochemical content (traces and minor elements) are more strongly correlated with macrofungal communities than vegetation (tree richness, dead wood, and litter volume) and climatic parameters (air temperatures and rainfall). At large scale, both edaphic and climatic factors, are considered essential for fungal fruiting and distribution across landscapes. The quantity of precipitation of the driest month is the crucial climatic factor influencing the occurrence of Porcini. The different results highlight a high variability and site dependence of both biotic and abiotic factors. Further studies appear to be necessary to increase knowledge on which factors have the most influence on edible and non-edible mushroom yield in various habitats. [ABSTRACT FROM AUTHOR]

Taylor, Katherine M., Feest, Alan, and Stephenson, Steven L.
- Abstract
Although the fruiting bodies of myxomycetes are commonly found associated with coarse woody debris in forest ecosystems throughout the world, there is no direct evidence that these organisms actually live within wood. In the research reported herein, surface sterilisation of pieces of wood taken from the branches of eight different tree species and the subsequent culturing of slivers of wood collected from within the interior of those branches clearly revealed the presence of the amoeboflagellates of myxomycetes. No evidence of the occurrence of plasmodia within wood was found, but amoeboflagellates emerged from 47 % of the wood slivers placed in culture. [ABSTRACT FROM AUTHOR]

Given the development of global pressures on habitats and biodiversity, it is important that developments are accompanied with a compensation element leading to 'no net loss'. We show how (using a standardised sampling process) a statistical assessment of the biodiversity quality of the target organisms (birds) in a compensatory provision can be shown to be a compensation or not. We used the example of the Cardiff Bay Barrage (Wales) where a bay was inundated and compensation site at Newport Gwent Levels (Wales) created. Bird data for the Cardiff Bay prior to the inundation and for Newport following inundation of Cardiff Bay were analysed to create a series of biodiversity quality indices and these were compared statistically. The analysis showed the compensation habitat was better than the original. Results were poor for Dunlin and Redshank, already subject to regional decline in the Severn Estuary and estuaries in NW Europe. [ABSTRACT FROM AUTHOR]

Abstract: Butterfly decline in Northern Europe is a cause of concern and it has been hypothesised that this is due to nitrogen deposition inducing excess early growth of plants. It has also been changing the quality of the food available to larvae. We tested these hypotheses by linking butterfly biodiversity quality indices (species richness, population, biomass, conservation value, evenness (Simpson's Index) and modelled species richness (Chao 1 and 2)) with nitrogen Critical Load Exceedence (nCLE) data. An index of butterfly sensitivity to nitrogen was also created (Species Nitrogen Value Index (SNVI)). Using PCA, datasets were tested for associations and relationships. The results included multiple biodiversity quality indices based on 17 years of data (aggregated into three periods of six, six and five years to give 287 datasets) in four habitat types (grassland, heathland, woodland and farmland). With the exception of heathland the analysis showed that nitrogen deposition and all other indices (except SNVI) were in decline. For heathland the last 11 years did not show any significant decline. Heathland also showed an anomalous biodiversity quality profile for these last 11 years, suggesting that the sensitivity of heathland to nitrogen deposition will require further considerable efforts to achieve a nitrogen deposition that is not in exceedence of the critical load. Habitat restoration will take time due to the multiple hindrances to colonisation, which in the case of heathland might prevent successful butterfly colonisation for the foreseeable future. These results indicate the efficacy of butterfly biodiversity quality and nCLE as indicators for the SEBI 2020 process (Streamlining European Biodiversity Indicators) by showing the relationship between them.

Abstract: The development of the Streamlining European Biodiversity Indicators 2010 (SEBI 2010) indicator set is described and critically reviewed for coverage and gaps. The indicator set is tested for historical background that would support trend analysis and found to be sensible, but the deficiency of direct biodiversity measurement rather than pressures on biodiversity is problematic. The lack of a freshwater biodiversity indicator is an obvious omission, whereas the analysis shows that two indicators (extent of protected areas and nitrogen deposition) have a central and important role in determining pressures on terrestrial biodiversity. A comparison with the UK Biodiversity Indicator Partnership annual assessment shows that this latter has better coverage at the biodiversity level and a simple method of presentation for an overall review. This has to be viewed with caution since disaggregation of the indicators shows contrary trends and even some misleading trends. Six recent papers proposing critical new indicators (three for invertebrates and three for freshwater ecosystems) are reviewed, and all are found to have deficiencies either in their sampling protocol or in the aim to produce a single headline value for a complex situation. The need for an ecosystem function approach to the measurement of biodiversity and the development of a common currency for measuring is expressed and compared to the results published by Butchardt et al. (2010) and Vačkář et al. (2012). [Copyright &y& Elsevier]

Eumycetozoans, commonly referred to as slime moulds, are common to abundant organisms in soils. Three groups of slime moulds (myxogastrids, dictyostelids and protostelids) are recognized, and the fi rst two of these are among the most important bacterivores in the soil microhabitat. The purpose of this paper is fi rst to provide a brief description of all three groups and then to review what is known about their distribution and ecology in soils. [ABSTRACT FROM AUTHOR]

Abstract: Spiders at 23 Portuguese protected area sites were sampled (pitfall trapped) over 10-month periods. The data allowed for a “biodiversity quality” assessment consisting of the following indices: Species Richness, Biomass, Simpson Index, Species Conservation Value Index and Population Density. These “biodiversity quality” characteristics were reviewed for relative indication of site spider “biodiversity quality”. Spiders are proposed as a group of organisms that could be used to indicate part of the “biodiversity quality” of a site since they can be sampled in a standardised way and yield biodiversity indices for comparison spatially and temporally. The approach adopted in this paper allows a range of “biodiversity quality” indices to be measured for spiders in Portuguese protected areas which, in turn requires decisions from scientists, managers and politicians on what element or characteristic of biodiversity it is intended to be targeted.

(1) This study examines the effect of increasing botanical diversity, through reed-bed planting and maintenance regimes, on sewage treatment reed-bed invertebrate biodiversity and the possible enrichment of overall catchment biodiversity. (2) Reedbed invertebrates were identified as a good indicator group of overall site biodiversity quality and were sampled at a range of sewage treatment reed-bed sites in the same geographical area between May and August 2006 (plus one natural reed-bed control site). Standardised water trapping and pitfall trapping techniques were employed throughout this sampling period. (3) Statistical analysis of the sampling results revealed that the number of plant species recorded was inversely related to terrestrial invertebrate species richness, species conservation value index and biomass within the study sites. For example, the natural reed-bed sampled had the highest botanical diversity but the lowest terrestrial invertebrate species richness. (4) This study has demonstrated that sewage treatment reed-beds support a diverse range of invertebrate species, some of them being of national conservation value. This suggests that sewage treatment reed-beds may be at least as biodiverse as naturally occurring reed-beds and will add to the overall biodiversity and ecohydrology of a catchment whilst saving energy.

Beech forests play an important role in temperate and north Mediterranean ecosystems in Greece since they occupy infertile montane soils. In the last glacial maximum, Fagus sylvatica (beech) was confined to Southern Europe where it was dominant and in the last thousand years has expanded its range to dominate central Europe. We sampled four different beech forest types. We found 298 insect species associated with beech trees and dead beech wood. While F. sylvatica and Quercus (oak) are confamilial, there are great differences in richness of the associated entomofauna. Insect species that inhabit beech forests are less than one fifth of those species living in oak dominated forests despite the fact that beech is the most abundant central and north European tree. There is a distinct paucity of monophagous species on beech trees and most insect species are shared between co-occurring deciduous tree species and beech. This lack of species is attributed to the vegetation history and secondary plant chemistry. Bark and leaf biophenols from beech indicate that differences in plant secondary metabolites may be responsible for the differences in the richness of entomofauna in communities dominated by beech and other deciduous trees.

Abstract: [1.] Recent political agreements mandate that the current rate of biodiversity loss is reduced by 2010 (the 2010 target). In Europe one of the 26 indicators given for this assessment is butterfly biodiversity which therefore requires butterfly biodiversity to be measured. advocates that this can be done using the concept of “Biodiversity Quality”. [2.] “Biodiversity Quality” measurement requires data analysis based on a series of indices examined both independently and jointly, rather than the use of a single measure such as species richness or a single composite index. We show that, where the theoretical base of sampling is sound, data collected with a simple analytical procedure in mind, can generate far more information than envisaged initially. An example of the compilation of “Biodiversity Quality” indicators is given for a site in the Dutch butterfly monitoring scheme (de Vlinderstichting) and two sites are compared for difference. [3.] A scheme showing how changes in the different indices might be interpreted to show change in biodiversity quality is given. [4.] These butterfly data are important from the perspective of the 2010 targets because: [(i)] they represent invertebrates, which comprise over half of all terrestrial species; [(ii)] they are based on relatively long time series; and [(iii)] they provide a model against which similar programmes can be designed for other taxonomic groups.

Abstract: This paper addresses the need for an internationally accepted definition of biodiversity the lack of which creates difficulty in measuring biodiversity difference and change. The authors suggest that well-sampled data can be used to generate a range of numerical indices reflecting species group characteristics/functionality that can be viewed in combination to create a picture of Biodiversity Quality. Examples of this approach demonstrate how to expand the currently accepted Convention on Biological Diversity definition, based on the “variability” of genes, species and ecosystems, since the numerical expression of the indices allows the probability of difference between biodiversity quality trends and values over time, and between sites or taxonomic groups, to be assessed for statistical inference of difference or similarity.

The need for standardized biodiversity assessment methods to enable biodiversity quality to be measured is outlined. A general approach to sampling is suggested. The results of the use of this sampling process are given for two case studies of different taxonomic groups. The data assessment is made easier by the use of a bespoke computer program. Examples of the program output are presented. The advantage of this standardized measurement of biodiversity compared to species lists and the use of indicator species are outlined in the case studies macrofungi and butterflies. It was shown that the biodiversity quality of sites can be compared by the use of a range of measured biodiversity indices in a way that allows sites to be compared through time or between sites/treatments. In one case (butterflies), data that have been collected systematically in a recording scheme have been analyzed retrospectively and yielded valuable information on changes in biodiversity quality. The uses of this method in establishing baselines in restoration ecology are discussed. The importance of restoration ecology in the conservation of biodiversity could be underlined by the use of the methods presented in this article. [ABSTRACT FROM AUTHOR]

2. Zero hunger ,13. Climate action ,15. Life on land ,580 Plants (Botany) - Abstract
Protists are the most diverse eukaryotes. These microbes are keystone organisms of soil ecosystems and regulate essential processes of soil fertility such as nutrient cycling and plant growth. Despite this, protists have received little scientific attention, especially compared to bacteria, fungi and nematodes in soil studies. Recent methodological advances, particularly in molecular biology techniques, have made the study of soil protists more accessible, and have created a resurgence of interest in soil protistology. This ongoing revolution now enables comprehensive investigations of the structure and functioning of soil protist communities, paving the way to a new era in soil biology. Instead of providing an exhaustive review, we provide a synthesis of research gaps that should be prioritized in future studies of soil protistology to guide this rapidly developing research area. Based on a synthesis of expert opinion we propose 30 key questions covering a broad range of topics including evolution, phylogenetics, functional ecology, macroecology, paleoecology, and methodologies. These questions highlight a diversity of topics that will establish soil protistology as a hub discipline connecting different fundamental and applied fields such as ecology, biogeography, evolution, plant-microbe interactions, agronomy, and conservation biology. We are convinced that soil protistology has the potential to be one of the most exciting frontiers in biology.

Macrofungi represent one of the most difficult taxonomic groups of organisms to study and monitoring the diversity over time and space often requires a high field sampling effort. Two different monitoring approaches were used to assess macrofungal biodiversity in broadleaf Mediterranean forests in order to determine whether different sampling efforts can provide statistically similar diversity indices. Despite the different number of field visits, the results obtained show that some biodiversity indices (e.g. Shannon index, Eveness, Simpson index) values do not seem to be significantly affected by the survey approach chosen and a single survey per year has achieved comparable results to multiple surveys. This, in a wider biodiversity context it could produce a quick field methodology to study complex taxonomic groups, such as macrofungi. [ABSTRACT FROM AUTHOR]

- Abstract
Biodiversity informatics plays a central enabling role in the research community's efforts to address scientific conservation and sustainability issues. Great strides have been made in the past decade establishing a framework for sharing data, where taxonomy and systematics has been perceived as the most prominent discipline involved. To some extent this is inevitable, given the use of species names as the pivot around which information is organised. To address the urgent questions around conservation, land-use, environmental change, sustainability, food security and ecosystem services that are facing Governments worldwide, we need to understand how the ecosystem works. So, we need a systems approach to understanding biodiversity that moves significantly beyond taxonomy and species observations. Such an approach needs to look at the whole system to address species interactions, both with their environment and with other species.It is clear that some barriers to progress are sociological, basically persuading people to use the technological solutions that are already available. This is best addressed by developing more effective systems that deliver immediate benefit to the user, hiding the majority of the technology behind simple user interfaces. An infrastructure should be a space in which activities take place and, as such, should be effectively invisible.This community consultation paper positions the role of biodiversity informatics, for the next decade, presenting the actions needed to link the various biodiversity infrastructures invisibly and to facilitate understanding that can support both business and policy-makers. The community considers the goal in biodiversity informatics to be full integration of the biodiversity research community, including citizens' science, through a commonly-shared, sustainable e-infrastructure across all sub-disciplines that reliably serves science and society alike.
