Abstract

The Mediterranean coralligenous substratum is a hard bottom of biogenic origin, mainly composed of calcareous algae, growing in dim light conditions. Sponges are among of the most representative taxa of the coralligenous assemblages, with more than 300 recorded species of different habits: massive, erect, boring and insinuating. When sponges die, their siliceous spicules remain trapped in the biogenic concretion, offering the opportunity to describe the coralligenous spongofauna over a very long span of time, virtually dating back to a large part of the Holocene period. The data reported here were obtained from core samples collected from four coralligenous concretions. Each block was collected in a different locality of the Ligurian Sea: Santo Stefano Shoals, Bogliasco, Punta del Faro ( Portofino Promontory) and Punta Manara. Radiocarbon age determinations indicate for these conglomerates a maximal age between 1600 and 3100 years. The spicules trapped in the cores show deep dissolution marks in the form of circular holes on their surface or present an enlargement of the axial canal. However, their original shape, generally intact, suggests the absence of mechanical injuries and allows a tentative identification at the species level. The analysis of these old spicules reveals an ancient sponge assemblage composed of 30 recognisable species. This indicates that almost one half of the sponge community today settled on coralligenous substrata has been present in the conglomerates for their entire existence. [ABSTRACT FROM AUTHOR]

Abstract

Abstract: Among the notothenioid fish, the Antarctic plunderfishes (family Artedidraconidae) are a poorly known component of the bottom fauna of the continental shelf despite their relative importance. The family is composed of 25 small- to medium-sized endemic species and four genera, Artedidraco, Dolloidraco, Histiodraco and Pogonophryne, which are the most benthic and sedentary of the notothenioid fish. In the framework of “Victoria Land Transect Project”, several samples of plunderfishes were collected by means of an Agassiz trawl. Sampling activities were carried out between 100 and 500m depth in five sites over nearly 4° latitude off Victoria Land. Overall, trawling yielded 80 specimens of plunderfish, including all species of Artedidraco reported from the Ross Sea, i.e. Artedidraco glareobarbatus, A. loennbergi, A. orianae, A. shackletoni and A. skottsbergi, and the monotypic genus Histiodraco. The use of multivariate statistical analyses on catch data indicated sampling site as the main factor affecting species composition. Histiodraco velifer and A. skottsbergi were caught almost exclusively in the southernmost sites, characterizing the artedidraconid fauna of Cape Russell. A. orianae was sampled only in the northernmost sites, such as Cape Adare and Hallett Peninsula. A. loennbergi appeared to be a ubiquitous species, whereas A. glareobarbatus was caught only at the Hallett Peninsula. Plunderfishes showed a particular distribution pattern in relation to depth as well. A. glareobarbatus was the shallowest species, being sampled within 100m. A. orianae and A. shackletoni showed a similar distribution, being caught mostly at 100–200m, whereas A. skottsbergi was mainly sampled at 200–300m. H. velifer was caught in a wide depth range, but mostly in deeper waters (400m). A. loennbergi was eurybathic, showing a wider depth distribution than other species. Univariate measures of diversity indicated Cape Adare as the poorer site in terms of species richness and diversity. Number of species, diversity and equitability were quite similar off Hallett Peninsula and Cape Russell, indicating the absence of a latitudinal trend. Generally, all univariate indices decreased from shallow (100m) to deep waters (500m). [Copyright &y& Elsevier]

182. Rate of spiculogenesis in some common Mediterranean Calcispongiae: A tetracycline and 45Ca++ labelling study

Author

Bavestrello, Giorgio, Cattaneo-Vietti, Riccardo, Cerrano, Carlo, Giovine, Marco, and Sara, Michele

Abstract

Calcareous spicule formation was studied using tetracycline and 45Ca++ tagging in Clathrina cerebrum (Haeckel), Ascandra falcata Haeckel and Sycon ciliatum (Fabricius) (Porifera: Calcispongiae). The percentage of fluorescent spicules 24 h after the start of the experiment was similar in C. cerebrum and A. falcata (about 13% of the whole spicular population), while no fluorescence occurred in S. ciliatum. Results from 45Ca++ labelling experiments were similar in C. cerebrum and S. ciliatum. Estimated rates of spicule production by tetracycline labelling (30 mg/g/day and 34 mg/g/day for Clathrina and Ascandra, respectively) were about four times greater than those by 45Ca++ tagging (8.2 mg/g/day and 8.1 mg/g/day for Clathrina and Sycon, respectively). Our data show that about 1-3% of sponge calcite in the three species examined reforms in 24 h, suggesting that a constant deposition rate of from one to three months is needed for a complete turnover of the total spicular population.

Author

Cattaneo-Vietti, Riccardo

Abstract

During the 2nd Italian Oceanographic Antarctic Expedition (1989–90) a small number of nudibranchs was collected at Terra Nova Bay (Ross Sea, Antarctica). In addition to well known species (such as Austrodoris kerguelensis Bergh, 1884 and Tritoniella belli Eliot, 1907) other, more unusual, species were also recorded, including Pseudotritonia gracilidens Odhner, 1944 and Cuthona georgiana (Pfeffer, 1884). Comparative information on the principal diagnostic features of the numerous species of Cuthona from the Sub-Antarctic and Antarctic waters is also tabulated and discussed.

Abstract

The Antarctic continent plays a fundamental role in the global climate system and its role is particularly important in a climate change scenario. Since the '90s, the Ross Sea and the coastal area of Terra Nova Bay have been chosen as specific and peculiar research sites for climatic investigations within the LTER (Long-Term Ecological Research) network. Studies have been conducted by both Italian and international Universities and research centres.This macro-site area is characterized by abundant primary productivity, and zooplankton and benthonic communities. The objective of the research activities is the acquisition of long-term time series related to the biotic communities, the bio-geochemical fluxes and the physico-chemical parameters of the water column in the Ross Sea area. To this aim, four Moorings (A, B, D and H) were deployed to obtain the above-mentioned data, which will be very useful to improve the quality of the existing bio-geochemical models and to provide more precise information on the Antarctic marine ecosystem in relation to global climate change. In the Terra Nova Bay research site, the activities are devoted to the characterization of the relationship between the structure and the dynamic of the pelagic and benthonic communities and the ice cover. Numerous physical, chemical and biological data were collected from the four Moorings, the water samples retrieved at the Terra Nova Bay site and the sediments samples. Such fundamental data allowed establishing an important starting point to better understand the climate change phenomena occurred in the last twenty years, and that will occur in the future, in the Ross Sea Area.

Abstract

Swimming activity of the Antarctic scallop at a temperature of c. -1.4 deg. C was analyzed using in situ video recordings obtained from aremotely operated vehicle (ROV) in Terra Nova Bay, Ross Sea. Data are presented on swimming trajectories, distance traveled and velocity during a swimming bout, adduction frequency, shell gape angle, and the angular opening and closing velocities of shell. This scallop is aneffective swimmer although swimming bouts in response to the ROV were generally short, consisting of 2-5 adduction cycles in the take-offphase followed by 1-4 (exceptionally 14) adductions during level swimming. The maximum velocity during each adduction cycle ranged from 19.4-43.1 cm s-1 and the mean velocity during a swimming bout from 12.0-23.5 cm s-1. Each adduction cycle consists ofopening, closing and glide phases of approximately equal duration. Adduction frequency during swimming averaged 1.5 adductions s-1. [ABSTRACT FROM AUTHOR]

Abstract

Marine bioconstructions are biodiversity-rich, three-dimensional biogenic structures, regulating key ecological functions of benthic ecosystems worldwide. Tropical coral reefs are outstanding for their beauty, diversity and complexity, but analogous types of bioconstructions are also present in temperate seas. The main bioconstructions in the Mediterranean Sea are represented by coralligenous formations, vermetid reefs, deep-sea cold-water corals, Lithophyllum byssoides trottoirs, coral banks formed by the shallow-water corals Cladocora caespitosa or Astroides calycularis, and sabellariid or serpulid worm reefs. Bioconstructions change the morphological and chemicophysical features of primary substrates and create new habitats for a large variety of organisms, playing pivotal roles in ecosystem functioning. In spite of their importance, Mediterranean bioconstructions have not received the same attention that tropical coral reefs have, and the knowledge of their biology, ecology and distribution is still fragmentary. All existing data about the spatial distribution of Italian bioconstructions have been collected, together with information about their growth patterns, dynamics and connectivity. The degradation of these habitats as a consequence of anthropogenic pressures (pollution, organic enrichment, fishery, coastal development, direct physical disturbance), climate change and the spread of invasive species was also investigated. The study of bioconstructions requires a holistic approach leading to a better understanding of their ecology and the application of more insightful management and conservation measures at basin scale, within ecologically coherent units based on connectivity: the cells of ecosystem functioning.

Abstract

The demosponge siliceous spicules, entrapped in the Mediterranean coralligenous bioherms, are a good tool for reconstructing the sponge ancient communities across time, also allowing a comparison with the current biodiversity. The aim of this paper has been the description of the ancient sponge assemblages of the coralligenous bioherms grown up in the Tavolara-Capo Coda Cavallo Marine Protected Area (northeastern Sardinia, Tyrrhenian Sea) between 5800 and 3700 YBP and its comparison with the living sponge community. On the base of radiocarbon age determinations, it was possible to estimate that these bioherms cover a span of time ranging from the Holocene Climatic Optimum until the Bronze Age Crisis. Their growth rates, 0.21–0.24 mm year −1 , were of the same order of estimations conducted around the Mediterranean. The Tavolara ancient sponge diversity was compared with those found in ancient accretions from Ligurian Sea and Ionian Sea. Our results supported the already-described general trend, supporting the hypothesis that the genus richness in the coralligenous bioherms was driven by climatic vicissitudes. Nevertheless, our data strongly indicated that the sponge diversity is also related to the conditions of the coralligenous structures: in the accretions characterized by an active growth of coralline algae the number of sponge genera is similar to those recorded in the ancient assemblages while in coralligenous where the accretion is stopped the number of sponge genera strongly decreases probably due to the competition with frondose macroalgae

Abstract

Marine bioconstructions are biodiversity-rich, three-dimensional biogenic structures, regulating key ecological functions of benthic ecosystems worldwide. Tropical coral reefs are outstanding for their beauty, diversity and complexity, but analogous types of bioconstructions are also present in temperate seas. The main bioconstructions in the Mediterranean Sea are represented by coralligenous formations, vermetid reefs, deep-sea cold-water corals, Lithophyllum byssoides trottoirs, coral banks formed by the shallow-water corals Cladocora caespitosa or Astroides calycularis, and sabellariid or serpulid worm reefs. Bioconstructions change the morphological and chemicophysical features of primary substrates and create new habitats for a large variety of organisms, playing pivotal roles in ecosystem functioning. In spite of their importance, Mediterranean bioconstructions have not received the same attention that tropical coral reefs have, and the knowledge of their biology, ecology and distribution is still fragmentary. All existing data about the spatial distribution of Italian bioconstructions have been collected, together with information about their growth patterns, dynamics and connectivity. The degradation of these habitats as a consequence of anthropogenic pressures (pollution, organic enrichment, fishery, coastal development, direct physical disturbance), climate change and the spread of invasive species was also investigated. The study of bioconstructions requires a holistic approach leading to a better understanding of their ecology and the application of more insightful management and conservation measures at basin scale, within ecologically coherent units based on connectivity: the cells of ecosystem functioning.

Abstract

Changes occurring over a pluri-millennial span of time (6207–1767 yr B.P.) within the sponge assemblages present in two coralligenous pillars, about 60 cm high, collected at 20 m depth, inside the Marine Protected Area of Porto Cesareo (Ionian Sea, Mediterranean Sea) have been studied. The sponge diversity has been analyzed at generic level, using as a proxy the siliceous spicules trapped into the sediment present into the crevices of these bioherms. In total, 41 genera of ancient demosponges were identified. The modern sponge fauna of these coralligenous pillars totals 31 genera, 15 of them shared with the ancient assemblages. The sponge biodiversity during the considered span of time showed critical changes, with remarkably similar trends in both the considered pillars. Tentatively, these changes were attributed to different climatic events that affected the Mediterranean area during the studied time span. The number of genera, 6000 yr B.P., was low and increased between 5500 and 4000 yr B.P. During the Late Bronze Age (4000–3000 yr B.P.), a new decrease was recorded, followed by a further increase around 2000 yr B.P. Afterwards, the bioherms stopped growing and no more siliceous spicules were trapped. From a biogeographic point of view, the wide presence of spiny microrhabdose microscleres belonging to the genus Alveospongia (Heteroxyidae), recently described from the tropical Atlantic and still unknown in the Mediterranean Sea, has to be underlined. In addition the trends recorded over time in the Ionian Sea match with those already observed in the Ligurian Sea. The comparison between the past periods and the modern one shows evident changes in biodiversity in both areas. The sharp variations of the seawater temperature - occurred in both the Mediterranean regions - could have driven the changes in genus richness. Using sponges to interpret the effects of climate changes can be a profitable strategy to unravel long term changes in biodiversity, supporting future predictions.

Abstract

1. Spread of alien species (AS) is a serious threat to marine habitats and analysis of principal descriptors of their occurrence is pivotal to set reliable conservation strategies. 2. In order to assess the susceptibility of marine habitats to biological invasions, a dataset was gathered of the occurrence of 3899 species from 29 phyla, taken from 93 marine sites located along the Italian coast in the period 2000–2012. 3. In total, 61 AS belonging to 11 phyla have been recorded. Invertebrates were the most represented (63%). Alien species were found in all the habitats examined (EUNIS, level 2), although they showed highest abundance in benthic habitats. Most of the AS were associated with a single EUNIS habitat, while some of them were present in more than one habitat. Trans-habitat occurrence suggests the potential invasiveness of AS. 4. According to statistical analysis, AS recorded could have been more numerous, since some of the marine habitats seemed to be still unsaturated. The model that best describes the spread of AS takes account of both native species richness (Rn) and EUNIS habitat type as explanatory variables. The number of observed AS was directly related to Rn and it was highest in rocky circalittoral and infralittoral habitats. 5. The results of this macro-ecological study focus on the importance of performing large-scale studies, since adopting ecosystem approaches to marine invasion management seems especially fruitful. 6. The results, moreover, highlight the importance of AS monitoring of different habitats, from those subjected to anthropogenic pressure, historically considered to be hubs of introduction of AS, to the most biologically rich and diverse marine habitats. Indeed, it is necessary to set monitoring strategies to detect the introduction, the distribution and persistence of AS over time. These recommendations are especially significant in the light of the strategic plans currently under formulation in Mediterranean countries with regard to AS monitoring
