Chondrichthyes occupy a key position in the phylogeny of vertebrates. The complete sequence mitochondrial genome (mitogenome) four species sharks and five rays was obtained by whole sequencing (DNA-seq) Illumina HiSeq2500 platform. arrangement features genes assembled mitogenomes were identical to those found Both Maximum Likelihood (ML) Bayesian Inference (BI) analyses used reconstruct phylogenetic relationships among 172 (including 163 retrieved from GenBank) based on concatenated dataset...
Abstract Citizen science (CS) expands the spatial and temporal scale of alien species records. As such, it has been recognized as a complementary tool in management large‐scale biodiversity conservation. The present study assessed contribution CS to recording marine fishes mollusks European waters by reviewing data available through Alien Species Information Network, portals, public databases, scientific literature. In total, 8,513 records were retrieved, following filtering procedure,...
The diet of the small-spotted catshark Scyliorhinus canicula, captured in Aegean Sea by bottom-trawl from 2006 to 2012, was investigated with respect sex, maturity condition, sampling location and season. stomach contents 432 specimens, measuring 144 517 mm total length, were analysed. cumulative prey curve showed that sample size adequate describe species’ diet, which quantified using percentage gravimetric composition (%W). identified items belonged eight major groups: Teleostei,...
Fish microbiome science is progressing fast, but it biased toward farmed or laboratory fish species against natural populations, which remain considerably underinvestigated. We analyzed the midgut bacterial microbiota of 45 specimens 12 collected from Gyaros Island marine protected area (Aegean Sea, Greece). The belong to seven taxonomic families and are either herbivores omnivores. Mucosa diversity was assessed by amplicon metabarcoding 16S rRNA V3-V4 gene region. A total 854 operational...
A total number of 526 Squalus blainvillei was sampled from the bottom trawl and longline catches in eastern Mediterranean Sea December 2004 to 2009. Females outnumbered males overall sex ratio 1.26:1. ranged 182 779 mm length 180 799 mm. Both females showed allometric growth (b > 3) we found statistically significant differences relationship between weight. Out specimens examined, 36% 63% were sexually mature. Males reached sexual maturity at smaller sizes than females. The smallest...
Squalus blainville is one of the least studied Mediterranean shark species. Despite being intensively fished in several locations, biological knowledge limited and no genetic structure information available. This first study to examine S. Sea. Considering high dispersal potential inferred for other squalid sharks, hypothesis panmixia was tested based on a 585 bp fragment mitochondrial DNA cytochrome c oxidase subunit I gene from 107 individuals six nuclear microsatellite loci 577...
The present work reports on the extended distribution of nineteen species in Mediterranean. These are: Upeneus pori(Fish:Turkey), Bursatella leachii (Mollusca, Opisthobranchia: eastern coast Spain), Sparisoma cretense (Fish: Ionian coastof Greece), Pseudobryopsis myura (Chlorophyta: Turkey), Aplysia dactylomela Karpathos island,and Kyklades Archipelago, Asparagopsis armata and Botryocladia madagascariensis (Rhodophyta: South Peloponnesos,Greece), Oxynotus centrina Caulerpa racemosa var....
Understanding reproductive features of elasmobranchs that affect population recovery and natural mortality is essential for conservation management planning. Considering macroscopic microscopic observations the tract in 2253 individuals, sampled Hellenic waters over a 7-year period, four stages were described. The presence advanced spermatocyst immature testes supported early gamete development long maturation process. simultaneous follicles all developmental mature ovaries indicated...
Evaluating environmental policies creates opportunities for harmonising and refining their implementation using a heuristic approach, considering the knowledge gaps in understanding complex processes. The European Union’s (EU) Marine Strategy Framework Directive (MSFD) is an ambitious legislation that brings together state, pressure, impact Descriptors of marine environment, built on ecosystem-based approach to management. Ultimately, aims achieve Good Environmental Status (GES) sustainable...
Abstract A total of 325 small-spotted catsharks, Scyliorhinus canicula, ranging from 263 to 488 mm in length (TL) and 62 395 g round weight (RW), were sampled trawl catches the Aegean Sea during two-year period 2005–2007. The overall ratio males females was 1.06:1, specimens almost 60% mature. size mature ranged between 371–488 364–467 length, respectively, while at 50% maturity estimated 396 for 399 females. Ovary varied 0.1 25.4 maximum oocyte diameter 18 mm. Gonadosomatic indices 0.13...
This Collective Article presents information about 17 taxa belonging to four Phyla (one Cnidaria, two Arthropoda, Mollusca, and ten Chordata) extending from the Western Mediterranean Levantine Sea. The new records were reported nine countries as follows: Algeria: first published of clingfishes Apletodon dentatus Lepadogaster lepadogaster after 1955; France: record tripletail Lobotes surinamensis in French waters; Italy: rare bonito Orcynopsis unicolor recently described nudibranch Elysia...
This study concerns the cephalopod species that are part of diet small-spotted catshark Scyliorhinus canicula and longnose spurdog Squalus blainville sampled by commercial trawlers in Aegean Sea from 2005 to 2012. Based on examined beaks, 15 were identified belonging six families Teuthida, one Sepiida two Octopoda. The diversity prey was higher for S. (N = 15) than 10). Nektonic cephalopods comprised majority (>72%) preyed both sharks, among which about 55% inhabit demersal zone 45%...
