Abstract

Data available on the Italian species of Copepoda Canuelloida Khodami, Vaun MacArthur, Blanco-Bercial and Martínez Arbizu, 2017 and Harpacticoida Sars, 1903 report overall 210 species, but their diversity and biogeography are still poorly investigated. We carried out a faunistic survey along the eastern coast of Sardinia (Ogliastra region) in order to document these taxa in the area. A total of 41 species in 36 genera and 18 families were found. Although many species were identified as putative, the current Italian checklist was updated with 12 new records of genera and 4 of species. Longipedia coronata Claus, 1862 (Canuelloida), Diosaccus tenuicornis (Claus, 1863), Asellopsis hispida Brady and Robertson, 1873, Wellsopsyllus (intermediopsyllus) intermedius (Scott and Scott, 1895) (all Harpacticoida) are reported for the first time from Sardinia coasts. The copepod community was particularly rich at Ogliastra Island, a small rocky island with natural reefs, rocky shoals and Posidonia oceanica meadows. Species found there were mainly related to coarse sands and macrophytal detritus. Data published in GBIF: doi:10.15470/dxru6l

Abstract

In total, 90 gelatinous spheres, averaging one meter in diameter, have been recorded from ~ 1985 to 2019 from the NE Atlantic Ocean, including the Mediterranean Sea, using citizen science. More than 50% had a dark streak through center. They were recorded from the surface to ~ 60–70 m depth, mainly neutrally buoyant, in temperatures between 8 and 24°C. Lack of tissue samples has until now, prohibited confirmation of species. However, in 2019 scuba divers secured four tissue samples from the Norwegian coast. In the present study, DNA analysis using COI confirms species identity as the ommastrephid broadtail shortfin squid Illex coindetii (Vérany, 1839); these are the first confirmed records from the wild. Squid embryos at different stages were found in different egg masses: (1) recently fertilized eggs (stage ~ 3), (2) organogenesis (stages ~ 17–19 and ~ 23), and (3) developed embryo (stage ~ 30). Without tissue samples from each and every record for DNA corroboration we cannot be certain that all spherical egg masses are conspecific, or that the remaining 86 observed spheres belong to Illex coindetii. However, due to similar morphology and size of these spheres, relative to the four spheres with DNA analysis, we suspect that many of them were made by I. coindetii.

12. Editorial: Extreme benthic communities in the age of global change

Abstract

The sea floor represents the largest solid ecosystem on our Planet. This heterogeneous realm consists of many different features shaped by millions of years of geological and chemical events, and biological and environmental evolution. “Extreme” benthic environments, defined as having abiotic conditions that demand organisms and resident communities be adapted in order to survive and thrive, are widespread and offer many opportunities for investigating the biological responses and adaptations of organisms to “abnormal” life conditions. At the same time, these adapted organisms may give insights into future ecosystem responses, as today's extreme ecosystems can be considered natural analogs of “normal” environments that may change under future climate change conditions. With continuing climate change and increased anthropogenic pressures, very few seafloor areas will remain untouched. Hence the future of the benthos will depend on how organisms, species, populations and communities will respond. Benthic communities are especially useful in long-term comparative investigations such as studying the effects of climate change and other pressures because most of their species are sessile or have low mobility, can be long-lived, and integrate the effects of environmental change over time. In addition, macro-, meio-, and microbenthos of hard and soft bottoms are found in almost any marine environment, including the most hostile or unusual, rendering them ideal to assess the impacts of environmental change and other pressures, as well as effects of multiple, simultaneous pressures. The continuous discovery of communities in extreme environments and the study of their variability, heterogeneity, and their relation to climate change and anthropogenic impacts, are slowly expanding as more evidence and long-term observations become increasingly available.

Abstract

In the Mediterranean biogenic habitat built by coralline algae (orders Corallinales, Hapalidiales and Sporolithales) show a great diversity and a large bathymetric extent. The genus Lithophyllum is the most species-diverse coralline genus. and plays a key role in the formation of extensive bioconstructions, as the coralligenous concretions in the circalittoral and the “trottoirs” in the mid littoral. As part of a large-scale investigation of the marine bioconstructions of the Italian shores, we account here some results on the distribution, diversity and ecology for L. byssoides, L. cabiochae and L. stictaeforme.

Abstract

Several individuals belonging to a new species of the genus Chromadorita (Nematoda: Adenophorea) were collected in a cold-seep area in the Gulf of Guinea during two French cruises: BIOZAIRE 2 (2001) and BIOZAIRE 3 (2003-2004) on board the R/V L'Atalante. In this area, rich chemosynthetic benthic communities have been discovered at 3150 m depth in the large pockmark field named Regab. Chromadorita regabi sp. nov. was found among the eggs in ovigerous specimens of the shrimp Alvinocaris muricola. The combination of long size (1500-2200 mu m), nine strong preanal papillae and relatively small dorsal tooth with weak musculature distinguishes this species from all known congeneric ones. An identification key to all known species of Chromadorita is provided.

Abstract

The management of the red coral, Corallium rubrum (L.), is an international issue still lacking of an effective solution in the Mediterranean Sea. The main goal of this research was the evaluation of the ROV efficiency as a monitoring non-destructive tool in studies concerning the conservation status of the deep red coral populations (living under 50 m depth). Both Ligurian Sea and Tuscan Archipelago are considered among the most important Italian historical sites of the red coral professional harvesting. Fishing effort in these areas is now decreased (in Liguria is virtually ceased) due to the drastic reduction of colonies of commercial size and thanks to conservation laws. Today, the protection of this natural resource has been directed mainly to coastal, shallow-water populations (living between 20 and 40 m depth), while the deeper banks, the main target of professional harvesting by technical scuba divers, still need dedicated management plans. ROV explorations allowed the identification of several deep red coral banks: in the Ligurian Sea, 6 out of 12 explored sites (50%) and in the Tuscan Archipelago, 7 out of 13 explored sites (50%). The banks may be considered almost "pristine" only around Montecristo Island. In the Ligurian Sea, the only deep population in a good conservation status is that of the Maledetti Shoal, off the Bergeggi Island MPA.

Abstract

In Europe, the Marine Strategy Framework Directive (MSFD) and the Water Framework Directive (WFD) are the main regulations for the protection of water bodies. The translation of their principles into valid and practical approaches is the main challenge for the scientific community. An additional and even more severe problem is related to the MSFD application in the Mediterranean area. The aim of the present contribution is to picture the present situation in Italy, as far as the benthic communities in the MSFD are concerned, pinpoint some conceptual and practical critical points, and possibly suggest some new tools useful for the definition of Good Ecological Status (GES).

Abstract

© The Author(s), 2015. This article is distributed under the terms of the Creative Commons Attribution License. The definitive version was published in Mediterranean Marine Science 16 (2015): 402-412, doi:10.12681/mms.1145., Much attention is currently devoted at upgrading our knowledge on biodiversity and functioning of deep water ecosystems. Information is constantly enriched by researchers, even from basins as the long-studied Mediterranean Sea. In such a perspective, we studied meiobenthic and nematode communities inhabiting muddy sediments from three different habitats at bathyal depths in the Strait of Sicily: a cold-water coral site (CS) in the Maltese Coral Province, a muddy bottom in the same area (MS), and a hydrocarbon imprinted pockmark site (PS) in the Gela Basin. The average meiofauna density at CS (1343 ind/10 cm2) and MS (1804 ind/10 cm2) is much higher than that reported in literature for similar habitats; it is also markedly more elevated than that recorded at PS (224 ind/10 cm2). Although nematodes of the three sites show different abundances, they share similar assemblage structure. Nematodes (avg. 86%) and copepods (avg. 9.3%) were the most abundant meiofaunal taxa at all sites followed by annelids, kinorhynchs and turbellarians. Nematodes were composed by 21 families and 46 genera, with Terschellingia, as most abundant genus (12.4%), followed by Microlaimus (11%), Daptonema (11%), Thalassomonhystera (10.8%), Acantholaimus (9.5%) and Sabatieria (8.7%). The genera Thalassomonhystera, Terschellingia, Microlaimus, Daptonema, Chromadorita, Sabatieria, and Anticoma display a dominance in at least one station. The taxonomic structure of meiofaunal communities of the studied sites is rather similar but differences in relative abundance are evident., Oceanographic research partly supported by CNR and the EU FP VI Integrated Projects HERMES (GOCE-CT-2005-511234-1) and HERMIONE (grant agreement no: 226354).
