A total of 212 species (or varieties) were identified, belonging to seven higher taxa: poriferans (24 species), cnidarians (32), molluscs (8), serpuloidean polychaetes (33), bryozoans (90), brachiopods (4) and ascidians (21). The combined use of a varied array of sampling methods was effective in obtaining a rich faunal inventory. Deep and offshore sites tended to be richer in species than shallow and inshore sites. In all cases species richness was higher at sites closest to hydrothermal vents on the sea floor. Although there are no comparable inventories of marine sessile epifauna in the Aegean, the high number of species found, with a relatively low sampling effort in a restricted area, indicates that the marine biodiversity of this sea is not as low as traditionally believed.10amarine1 aMorri, C.1 aBianchi, C., N.1 aCocito, S.1 aPeirano, A.1 ade Biase, A., M.1 aAliani, S.1 aPansini, M.1 aBoyer, M.1 aFerdeghini, F.1 aPestarino, M.1 aDando, P., R. uhttps://icgf.myspecies.info/content/biodiversity-marine-sessile-epifauna-aegean-island-subject-hydrothermal-activity-milos00515nas a2200133 4500008004100000245007400041210006800115300001300183490000700196653003200203100003200235700001700267856009700284 1973 eng d00aThe cladocerans of the Aegean Sea.

Ninety composite haplotypes were revealed with the number of haplotypes in each population sample ranging from 4 to 31. Private haplotypes were found at very low frequencies. The global exact test of sample differentiation based on composite haplotype frequencies was statistically significant. FST analyses also showed significant heterogeneity among the European lobster population samples (FST = 0.078, P < 0.001). This differentiation was mainly due to the population samples from northern Norway, the Netherlands, and the Mediterranean Sea. These samples differentiated from the rest due to reduced gene diversity rather than to unique haplotypes. The relationships among these samples were illustrated with cluster analyses; four major distinct groups were evident: Mediterranean, northern Norway, Netherlands, and the remaining Atlantic samples. Based on the low degree of differentiation revealed in the European lobster and its limited capacity for dispersal, the most probable hypothesis is that all populations have been established from a common refuge after the end of the last Ice Age, that is, within the past 15,000 years. The results of this study show that mitochondrial DNA is a powerful tool for the determination of the genetic structure among lobster samples, which is important for a proper management policy designed to protect and to cultivate this species. © Springer-Verlag 2004.10aCrustacea Decapoda1 aTriantafyllidis, A.1 aApostolidis, A.P.1 aKatsares, V.1 aKelly, E.1 aMercer, J.1 aHughes, M.1 aJorstad, K.E.1 aTsolou, A.1 aHynes, R.1 aTriantaphyllidis, C. uhttps://icgf.myspecies.info/content/mitochondrial-dna-variation-european-lobster-homarus-gammarus-throughout-range00630nas a2200145 4500008004100000245015000041210006900191260001300260300001200273490000800285653002300293100002500316700001700341856012600358 1997 eng d00aEstimation of the reproductive output of the burrowing shrimp Callianassa tyrrhena: a comparison of three different biometrical approaches0 aEstimation of the reproductive output of the burrowing shrimp iC bSpringer a435-4420 v12710aCrustacea Decapoda1 aThessalou-Legaki, M.1 aKiortsis, V. uhttps://icgf.myspecies.info/content/estimation-reproductive-output-burrowing-shrimp-callianassa-tyrrhena-comparison-three02543nas a2200277 4500008004100000245013600041210006900177260000800246300001200254490000800266520162200274653002801896653002101924653001401945653001401959653001601973653001201989653001702001653002602018653001602044653001802060100002502078700001402103700001802117856013002135 1999 eng d00aFacultative lecithotrophy during larval development of the burrowing shrimp Callianassa tyrrhena (Decapoda : Callianassidae)0 aFacultative lecithotrophy during larval development of the burro cMAY a635-6420 v1333 aSurvival, developmental and consumption rate (Artemia nauplii ingested per day) as well as predation efficiency (ingested per available Artemia nauplii) were studied during the larval development of the shallow-water burrowing thalassinid Callianassa tyrrhena (Petagna, 1792), which exhibits an abbreviated type of development with only two zoeal stages and a megalopa. The larvae, hatched from berried females from S. Euboikos Bay (Aegean Sea, Greece), were reared at 10 temperature-food density combinations (19 and 24 degrees C; 0, 2, 4, 8 and 16 Artemia nauplii d(-1)). Enhanced starvation resistance was evident: 92 and 58% of starved zoeas I molted to zoea II, while metamorphosis to megalopa was achieved by 76 and 42% of the hatched zoeas at 19 and 24 degrees C, respectively. The duration of both zoeal stages was affected by temperature, food density and their interaction. Nevertheless, starvation showed different effects at the two temperatures: compared to the fed shrimp, the starved zoeae exhibited accelerated development at 19 degrees C (8.4 d) but delayed metamorphosis at 24 degrees C (5.9 d). On the other hand, both zoeal stages were able to consume food at an increased rate as food density and temperature increased. Predation efficiency also increased with temperature, but never exceeded 0.6. Facultative lecithotrophy, more pronounced during the first zoeal stage of C. tyrrhena, can be regarded as an adaptation of a species whose larvae can respond physiologically to the different temperature-food density combinations encountered in the wide geographical range of their natural habitat.10aabbreviated development10abrachyuran crabs10aCrustacea10agrapsidae10apalinuridae10aperiods10arequirements10astarvation resistance10atemperature10athalassinidea1 aThessalou-Legaki, M.1 aPeppa, A.1 aZacharaki, M. uhttps://icgf.myspecies.info/content/facultative-lecithotrophy-during-larval-development-burrowing-shrimp-callianassa-tyrrhena03225nas a2200181 4500008004100000245009900041210006900140260001200209300001200221490000800233520252200241653009102763100001802854700002002872700001702892700001402909856012002923 1997 eng d00aBenthic fauna of a shallow-water gaseohydrothermal vent area in the Aegean Sea (Milos, Greece)0 aBenthic fauna of a shallowwater gaseohydrothermal vent area in t c1997/// a149-1590 v1283 aThe benthic community of shallow-water hydrothermal vents (10 m water depth) in a sandy bay on the south coast of Milos, Greece was studied. The macro- and meiofauna, as well as environmental factors such as temperature, salinity, sulfide concentration, grain size composition, ATP concentration, organic carbon, chlorophyll a and phacopigments were evaluated. Samples were taken along transects from a seagrass meadow into a hydrothermally active area. Hydrothermally active spots were distinguished from the surrounding sediment by their black sediment coloration and an overlying white bacterial mat. For comparison, a control transect from a seagrass meadow into bare sand in a non-vent area in the same bay was studied. Overall, we found decreasing faunal diversity from the seagrass bed towards the hydrothermally active area. Along this gradient, four different zones could be distinguished. (a) The seagrass area had a relatively low diversity compared to the control stations, but much higher diversity than in the areas directly influenced by hydrothermal activity. (b) The border zone between the seagrass and the hydrothermal area, with moderate sulfide concentrations, pH values, seawater salinity and temperatures, was inhabited by an impoverished community dominated by the polychaete Capitella capitata, the nematodes Oncholaimus campylocercoides and Sabatieria sp., and an as yet undescribed chromadorid nematode (Chromadorina sp.). (c) The transition zone at the border of the hydrothermal area proper, with temperatures and sulfide concentrations higher than in the border zone, was characterized by high salinity (60?) and low pH values. Along with the gastropod Cyclope neritea, single specimens of C. capitata and O. campylocercoides occurred. (d) The hydrothermal area proper, characterized by high sulfide concentrations, had high sediment temperatures and high salinities. The pH was as low as 6. Here, the gastropod Cyclope neritea was the only species occurring in considerable numbers. The gaseohydrothermal activity seems to largely exclude the surrounding farina in a graded zonal pattern. The increasing hydrothermal stress entrains a change of the ambient biota towards a depauperate consortium of tolerant, opportunistic species, e.g. Capitella capitata (Polychaeta) and Oncholaimus campylocercoides (Nematoda). Although the hydrothermal area proper was characterized by a thick bacterial mat, the benthic community was characterized not by bacteria feeders but by scavenging species.10akape Annelida Polychaeta Nematoda Mollusca Gastropoda Oligochaeta Crustacea Tanaidacea1 aThiermann, F.1 aAkoumianaki, I.1 aHughes, J.A.1 aGiere, O. uhttps://icgf.myspecies.info/content/benthic-fauna-shallow-water-gaseohydrothermal-vent-area-aegean-sea-milos-greece02818nas a2200241 4500008004100000245008200041210006900123260001200192300001400204490000800218520206600226653001102292100002302303700001802326700001902344700001802363700001702381700001702398700001602415700001702431700002002448856010802468 2004 eng d00aMesozooplankton communities in the Aegean and Black Seas: A comparative study0 aMesozooplankton communities in the Aegean and Black Seas A compa c2004/// a1111-11260 v1443 aAn attempt was made for a comparative study of the mesozooplankton communities between the Aegean and Black Seas. These areas are in connected through the Sea of Marmara, the Bosporus and the Dardanelles straits. The comparison was mainly based on data collected both in coastal and offshore waters, by the Hellenic Centre for Marine Research (Greece), the Shirshov Institute of Oceanology (Russia), the Institute of Biology of Southern Seas (Ukraine) and the Institute of Oceanology (Bulgaria). Our data revealed important differentiation in terms of species composition and interannual fluctuations of zooplankton quantity. Among the common copepod species, those presenting an eurytherm and/or euryhaline character (e.g. Acartia clausi, Paracalanus parvus, Penilia avirostris, Podon polyphemoides) were found dominant in the Black Sea and common in the Aegean Sea. Decreased dissimilarity of species composition seems to exist between the North Aegean Sea and the Black Sea, as well as between the coastal areas of the Black Sea and those affected by pollution in the Aegean Sea. A common feature of both seas is the existence of spatial differentiation in terms of the quantity of zooplankters due to anthropogenic and/ or natural influences. The pattern of this differentiation seems to vary interannually in the Black Sea, depending either on the abundance of mesozooplankton predators (indigenous or invasive species) or on global climatic changes. Although the Black Sea is generally richer in zooplankton than the Aegean Sea, the significant decrease in the quantity of zooplankton from the early 1980s to the mid-1990s, due to the above factors, resulted in quasi-similar values in both areas. Black Sea mesozooplankton has revealed strong interannual variability both quantitatively and qualitatively, whereas no significant variability was detected in the Aegean Sea. This difference could be attributed both to variant anthropogenic forcing on these ecosystems and to the sensitive character of the semi-enclosed Black Sea. © Springer-Verlag 2004.10amarine1 aSiokou-Frangou, I.1 aShiganova, T.1 aChristou, E.D.1 aKamburska, L.1 aGubanova, A.1 aKonsulov, A.1 aMusaeva, E.1 aSkryabin, V.1 aKhoroshilov, V. uhttps://icgf.myspecies.info/content/mesozooplankton-communities-aegean-and-black-seas-comparative-study03463nas a2200325 4500008004100000245014100041210006900182260000800251300001200259490000800271520242800279653001402707653001502721653000902736653001102745653002102756653001402777653001702791653001602808100002202824700002102846700002402867700002002891700002302911700001902934700002102953700001902974700001902993856012503012 2001 eng d00aPopulation development of the invader ctenophore Mnemiopsis leidyi, in the Black Sea and in other seas of the Mediterranean basin0 aPopulation development of the invader ctenophore iMnemiopsis lei cSEP a431-4450 v1393 aIn the last two decades of the twentieth century, the ctenophore Mnemiopsis leidyi (A. Agassiz) has invaded the Black, Azov, Marmara and Aegean Seas, and, recently, the Caspian Sea. Here, we compare its spatial and temporal distribution, seasonal dynamics and the time and duration of reproduction. We also discuss factors that control its abundance throughout its invasive range and its effect on ecosystems. Observations are based on the long-term field data collected by three research institutes. An analysis of the effects of temperature, salinity, prey (zoo- and ichthyoplankton) availability and predation (by ctenophores of the genus Beroe) on M. leidyi population size, and the effects of M. leidyi on zoo- and ichthyoplankton, and on fish populations in the Black and Azov Seas is also provided. With the Black Sea current, M. leidyi spreads to the upper layers of the Sea of Marmara, where it now occurs around the year. At regular intervals, the Black Sea current also takes it to the northern Aegean Sea. In contrast, it has to re-invade the Sea of Azov every spring or summer, dying out during winter when the temperature drops below 4 degreesC. The warm summer and mild winter temperatures, relatively low salinity and abundance of prey in the Black Sea are close to optimal for M. leidyi, while they are suboptimal in the northern Aegean Sea, where salinity and temperature are often too high. In the Black Sea the absence of gelatinous and other predators led to an enormous ctenophore abundance for a decade, but with the appearance of Beroe ovata in 1999, M. leidyi abundance greatly decreased. Analysis of seasonal dynamics of M. leidyi in the Black Sea and in other seas of the Mediterranean basin indicates similarities in the timing of maximum abundance and biomass, in spite of some differences in the initiation and duration of reproduction. A peak biomass and density occurred in 1989 in the Black and Azov Seas and in 1990 in the other seas. The M. leidyi invasion negatively affected the ecosystems of the Black Sea and the Sea of Azov. The zooplankton, ichthyoplankton and zooplanktivorous fish stocks all underwent profound changes. Similar effects, but less pronounced, were recorded in the Sea of Marmara. Effects on Mediterranean food chains have, so far, remained insignificant. Salinity is probably supraoptimal here, and several predators prevent M. leidyi from reaching outbreak levels.10aabundance10aCtenophora10afood10alobata10anarragansett bay10apredation10arhode-island10azooplankton1 aShiganova, T., A.1 aMirzoyan, Z., A.1 aStudenikina, E., A.1 aVolovik, S., P.1 aSiokou-Frangou, I.1 aZervoudaki, S.1 aChristou, E., D.1 aSkirta, A., Y.1 aDumont, H., J. uhttps://icgf.myspecies.info/content/population-development-invader-ctenophore-mnemiopsis-leidyi-black-sea-and-other-seas02396nas a2200157 4500008004100000245018400041210007100225260001300296300001200309490000800321520172600329653001302055100001702068700002102085856013202106 2006 eng d00aPhylogeny and geographic differentiation of Atlanto–Mediterranean species of the genus Xantho (Crustacea: Brachyura: Xanthidae) based on genetic and morphometric analyses0 aPhylogeny and geographic differentiation of Atlanto–Mediterranea bSpringer a853-8660 v1483 aThe crab genus Xantho Leach, 1814 is restricted to the northeastern Atlantic Ocean and the Mediterranean Sea. It consists of four species, Xantho hydrophilus (Herbst, 1790), X. poressa (Olivi, 1792), X. pilipes A. Milne-Edwards, 1867, and X. sexdentatus (Miers, 1881). X. hydrophilus has been divided into two geographic forms, of which one, X. h. granulicarpus (Forest, 1953), is postulated to be endemic to the Mediterranean Sea. In this study, we reconstruct phylogenetic relationships of the genus Xantho and related genera from the Atlantic Ocean or Mediterranean Sea and compare different geographic populations of Xantho hydrophilus and, to a lesser extent, of X. poressa by means of population genetic and morphometric analyses. The molecular phylogeny is based on two mitochondrial genes (large subunit rRNA and cytochrome oxidase I) and indicates that X. poressa, X. hydrophilus and X. sexdentatus form a monophyletic group, the latter two species sharing identical haplotypes. On the other hand, X. pilipes shows affinities to Xanthodius denticulatus. Population genetics based on the COI gene reveal genetic differentiation within X. hydrophilus. Morphometric results also give evidence for distinct geographic forms in X. hydrophilus with a clear discrimination. In comparison, morphometric discrimination between different geographic populations of X. poressa is less clear, but still significant. We therefore suggest a recent/ongoing morphological and genetic differentiation within Xantho hydrophilus, restricted gene flow between its Atlantic and Mediterranean populations (not allowing subspecific differentiation) and possible mtDNA introgression between the species X. hydrophilus and X. sexdentatus.10aDecapoda1 aReuschel, S.1 aSchubart, C., D. uhttps://icgf.myspecies.info/content/phylogeny-and-geographic-differentiation-atlanto%E2%80%93mediterranean-species-genus-xantho00567nas a2200133 4500008004100000245010300041210006900144300001400213490000800227653001600235100002300251700002900274856013000303 2006 eng d00aPlanktivorous damselfish support significant nitrogen and phosphorus fluxes to Mediterranean reefs0 aPlanktivorous damselfish support significant nitrogen and phosph a1089-10990 v14810akape pisces1 aPinnegar, John, K.1 aPolumin, Nicholas, V.

Appropriate molecular markers are particularly suitable for distinguishing cryptic biological species. In this study, we examine the phylogenetic utility of 16S rRNA in elucidating the evolutionary relationships within the recently described euryhaline Brachionus plicatilis species complex. In addition, we assess the applicability of this marker in the genetic identification and monitoring of rotifer populations. We have sequenced a 378-bp fragment of the mitochondrial 16S rRNA gene in laboratory reference strains, hatchery clones as well as collections from a wild population of the subsaline Lake Koroneia (Northern Greece). Also, restriction fragment length polymorphism (RFLP) analysis was performed with eight restriction endonucleases. Rotifer samples are distinguished into six genetically divergent lineages. Average sequence divergence between lineages is 0.1038. The evolutionary relationships and divergence time-scales revealed with the 16S sequence data are in agreement with previous analyses using different mitochondrial and nuclear markers. The 16S region appears to have several advantages over other regions of the genome regarding use of species-specific primers, ease of amplification from single specimens and undiluted informational content over both recent and more ancient separations. It has also exhibited maximum discriminatory power (100% success) between lineages during RFLP analysis. The 16S assayed region has proven especially informative and consistent in detecting, supporting and establishing the lineage status within the B. plicatilis species complex both from a phylogenetic perspective and as an identification tool. © Springer-Verlag 2005.10aRotifera1 aPapakostas, S.1 aTriantafyllidis, A.1 aKappas, I.1 aAbatzopoulos, Theodoros, J. uhttps://icgf.myspecies.info/content/utility-16s-gene-investigating-cryptic-speciation-within-brachionus-plicatilis-species00595nas a2200145 4500008004100000245013000041210006900171260001300240300001200253490000800265653001300273100001500286700001900301856012900320 2003 eng d00aPhylogeography of Cerastoderma glaucum (Bivalvia: Cardiidae) across Europe: a major break in the Eastern Mediterranean0 aPhylogeography of iCerastoderma glaucum iBivalvia Cardiidae acro bSpringer a339-3500 v14310aMollusca1 aNikula, R.1 aVäinölä, R. uhttps://icgf.myspecies.info/content/phylogeography-cerastoderma-glaucum-bivalvia-cardiidae-across-europe-major-break-eastern01563nas a2200169 4500008004100000245015600041210006900197260001300266300001200279490000800291520089500299653001301194100001601207700001701223700002101240856013201261 2002 eng d00aGenetic structuring and gene flow in Cerastoderma glaucum (Bivalvia: Cardiidae): evidence from allozyme variation at different geographic scales0 aGenetic structuring and gene flow in iCerastoderma glaucum iBiva bSpringer a687-6970 v1403 aGenetic variation at 16 enzyme loci was analysed in 20 Mediterranean and 1 Baltic population of Cerastoderma glaucum. Spatial genetic variation at different geographic scales was investigated. In general, this species was fairly genetically structured (over all loci θ=0.088), according to the fragmentary nature of its habitat. Spatial structuring of genetic diversity was shown to follow different models, depending on the geographic scale considered: a stepping-stone model provided a good fit at a wide scale, with gene flow inversely related to geographic distance, whereas at small scale, genetic relationships among samples could not be interpreted as simply the effect of physical distance among populations. Results are discussed taking into account the intrinsic and extrinsic factors which are most likely to affect the patterns of genetic structuring in coastal marine animals.10aMollusca1 aMariani, S.1 aKetmaier, V.1 aDe Matthaeis, E. uhttps://icgf.myspecies.info/content/genetic-structuring-and-gene-flow-cerastoderma-glaucum-bivalvia-cardiidae-evidence-allozyme02004nas a2200169 4500008004100000245015400041210006900195260001200264300001200276490000800288520133500296653001101631100001601642700002201658700002501680856012901705 1998 eng d00aGenetic protein variation in red mullet (Mullus barbatus) and striped red mullet (M. surmuletus) populations from the Mediterranean sea0 aGenetic protein variation in red mullet iMullus barbatusi and st c1998/// a353-3600 v1303 aStarch-gel electrophoresis of allozymes was used to differentiate the two red mullet species (Mullus barbatus L. and M. surmuletus L.) in the Mediterranean Sea and, further, to investigate the genetic stock structure of M. barbatus in the eastern Mediterranean area.

In the present study morphometric data from 435 specimens collected from Greece (Crete), Italy (Ionian Sea) and the Atlantic coast of France from September 1999 to March 2001 were analyzed to estimate the settlement size of the species and associated changes in morphology. The fishery sample included specimens from both the pelagic and the demersal stage. Length-at-settlement (TL50) and 95% confidence intervals were estimated by fitting a logistic function. Eleven morphometric characters were analyzed, and the existing inflection points, reflecting alterations in body shape, were defined: (1) iteratively, as the transition point, splitting the data set into two groups, for which the reduced major axis functions, between a character and total length, of the successive groups best fit (minimum sum of squares of residuals) the combined data set and (2) where the second derivative of the fitted third-order polynomial functions to morphometric ratios equaled zero. The main size range within which wreckfish settled was 56-65 cm, and the means of the inflection points defined by the two methods were 61 and 64 cm. These results indicate changes in functional morphology associated with settlement. The monitoring of wreckfish juveniles caught in the wild and kept individually in captivity showed changes in growth and food intake at approximately the estimated settlement length and suggested that temperature was the most likely factor triggering settlement.10aPisces1 aMachias, A.1 aSomarakis, S.1 aPapadroulakis, N.1 aSpedicato, M.-T.1 aSuquet, M.1 aLembo, G.1 aDivanach, P. uhttps://icgf.myspecies.info/content/settlement-wreckfish-polyprion-americanus02511nas a2200145 4500008004100000245011300041210006900154260001200223300001200235490000800247520194600255100001502201700001902216856013002235 1996 eng d00aEvolution and systematics in Haliotidae (Mollusca: Gastropoda): Inferences from DNA sequences of sperm lysin0 aEvolution and systematics in Haliotidae Mollusca Gastropoda Infe c1996/// a267-2780 v1243 aAbalone taxonomy and systematics have remained unresolved: neither stable species-level nomenclature nor a cladistic hypothesis of relationships among species have been established. To infer the phylogeny of the genus Haliotis and to identify species using molecular data, we compared complementary DNA (cDNA) sequences of sperm lysin from 27 species- group taxa from California, Japan, Australia, New Zealand, Taiwan, Borneo, Madagascar, South Africa, Greece, France, Italy and the Azores. The lysin cDNA sequences reveal that 22 of the 27 taxa are clearly distinguishable by > 20 nucleotide differences. Of the remaining 5, H. coccinea from the Azores may be a subspecies of H. tuberculata, if not a sibling species (10 nucleotide differences). The other four taxa are most probably the same species as one of the 22 taxa: the lysin sequences are almost identical between H. madaka and H. discus hannai, H. conicopora and H. rubra, H. diversicolor supertexta and H. diversicolor aquatilis, and H. tuberculata lamellosa and H. tuberculata tuberculata. The phylogeny of lysin cDNA suggests that there are three groups among the 27 species-group taxa: (1) all California species and 3 Japanese species (H. gigantea, H. discus hannai, and H. madaka); (2) 1 New Zealand species (H. iris); (3) 1 Japanese species (H. diversicolor aquatilis), Indo-West Pacific species and European species. These groups can be assigned to three previously recognized subgenera (Nordotis, Paua and Padollus) in the genus Haliotis. Two historical hypotheses are proposed to explain the biogeography and evolution within these abalone: (1) Tethyan distribution of the ancestral abalone during the Cretaceous, followed by extinction in most of the habitat, but radiation in California and Southeast Asia which later spread to the other areas; (2) North Pacific rim distribution of the ancestral abalone, followed by dispersal to the other areas during the Paleogene.1 aLee, Y.-H.1 aVacquier, V.D. uhttps://icgf.myspecies.info/content/evolution-and-systematics-haliotidae-mollusca-gastropoda-inferences-dna-sequences-sperm-000577nas

turtles Caretta c bSpringer a1269-12790 v1493 aAbstract The analysis of mitochondrial DNA in loggerhead sea turtles (Caretta caretta) from eight foraging grounds in the Mediterranean and the adjoining Atlantic revealed deep genetic structuring within the western Mediterranean. As a consequence, the foraging grounds off the North-African coast and the Gimnesies Islands are shown to be inhabited mainly by turtles of the Atlantic stocks, whereas the foraging grounds off the European shore of the western Mediterranean are shown to be inhabited mainly by turtles from the eastern Mediterranean rookeries. This structuring is explained by the pattern of sea surface currents and water masses and suggests that immature loggerhead sea turtles entering the western Mediterranean from the Atlantic and the eastern Mediterranean remain linked to particular water masses, with a limited exchange of turtles between water masses. As the north of the western Mediterranean comprises mostly individuals from the highly endangered eastern Mediterranean rookeries, conservation plans should make it a priority to reduce the mortality caused by incidental by-catch in these areas.10aReptilia1 aCarreras, C.1 aPont, S.1 aMaffucci, F.1 aPascual, M.1 aBarceló, A.1 aBentivegna, F.1 aCardona, L.1 aAlegre, F.1 aSanFélix, M.1 aFernández, G. uhttps://icgf.myspecies.info/content/genetic-structuring-immature-loggerhead-sea-turtles-caretta-caretta-mediterranean-sea00558nas a2200133 4500008004100000245011900041210006900160260001300229300001200242490000800254653001300262100001900275856013000294 2002 eng d00aIntra-Mediterranean migrations of loggerhead sea turtles (Caretta caretta) monitored by satellite telemetry0 aIntraMediterranean migrations of loggerhead sea turtles iCaretta bSpringer a795-8000 v14110aReptilia1 aBentivegna, F. uhttps://icgf.myspecies.info/content/intra-mediterranean-migrations-loggerhead-sea-turtles-caretta-caretta-monitored-satellite
