abstract = {Life-history, substrate choice and Cytochrome Oxidase I (COI) sequences were analysed in populations of two peracaridans, the supralittoral talitrid Atlantorchestoidea brasiliensis and the intertidal cirolanid Excirolana armata. Three populations of each species, from beaches with similar grain size and located at different points along the natural gradient generated by the Rio de la Plata estuary were analysed. Abundance of E. armata increased with distance from the estuary, while the opposite trend was observed for A. brasiliensis. The proportion of females decreased towards high salinities for both species, significantly for E. armata. A test on substrate salinity preference revealed the absence of patterns due to active choice in E. armata. By contrast, A. brasiliensis showed no preference for the population closer to the estuary, while individuals from the other two sites significantly preferred high salinity substrates. Mitochondrial COI sequences were obtained from A. brasiliensis specimens tested for behaviour. Sequence analysis showed the population from the intermediate site to differ significantly from the other two. No significant genetic differentiation was instead found between populations from the two most distant sites, nor between individuals that expressed different salinity preference. Results showed that diverse sets of traits at the population level enable sandy beach species to cope with local environmental changes: life-history and behavioural traits appear to change in response to different ecological conditions, and, in the case of A brasiliensis, independently of the population structure inferred from COI sequence variation. Information from multiple traits allowed detection of population profiles, highlighting the relevance of multidisciplinary information and the concurrent analysis of field data and laboratory experiments, to detect responses of resident biota to environmental changes. © 2017 Elsevier Ltd},

abstract = {The alpha taxonomy of the globally distributed shark genus Squalus has been under intense investigation recently, and many new species have been described over the last decade. However, taxonomic uncertainty remains about several taxa. Without consistent nomenclature and the ability to reliably distinguish between the different Squalus species, basic data collection, downstream conservation and management efforts are seriously compromised. To aid in clarifying the taxonomic status of Squalus species in the eastern Atlantic and Mediterranean, we assessed species diversity at the molecular level and evaluated the consistency in species identification in the region. Samples from all nominal Squalus species recognized in the above regions were collected in an international effort and sequenced for regions of the mitochondrial COI and ND2 genes. These data were further analysed alongside publicly available sequences, including 19 of the 26 Squalus species globally recognized, to compare the regional genus-level diversity with that found elsewhere. Our results confirm inconsistent species identification in the eastern Atlantic and Mediterranean Squalus, particularly concerning S. blainville and S. megalops, and reinforce the need to revise the status of S. megalops and S. mitsukurii as they may include several distinct species distributed around the world. The status of S. blainville is also discussed in the light of the current findings and its problematic taxonomic history. © 2016 Royal Swedish Academy of Sciences},

abstract = {The biological works of the Greek philosopher Aristotle include a significant amount of information on marine animals. This study is an overview of Aristotle's scientific contribution to the knowledge of marine biodiversity and specifically to taxonomic classification, nomenclature and distribution of marine species. Our results show that Aristotle's approach looks remarkably familiar to present day marine biologists since: (i) although not directly aiming at it, he gave a taxonomic classification of marine animals, which includes physical groups ranked on three levels at least; (ii) most of Aristotle's marine "major groups" correspond to taxa of the order rank in Linnaeus's classification and to taxa of the class rank in the current classification; (iii) a positive correlation was found between the number of taxa per group identified in Aristotle's writings and those described by Linnaeus; (iv) Aristotle's classification system exhibits similarities with the current one regarding the way taxa are distributed to higher categories; (v) a considerable number of Aristotle's marine animal names have been used for the creation of the scientific names currently in use; (vi) he was the first to give an account of Mediterranean marine fauna, focusing on the Aegean Sea and adjacent areas. In view of the above, we suggest that the foundations of marine taxonomy as laid down by Aristotle are still echoing today. © 2017, Hellenic Centre for Marine Research.},

Commercial sized fish were affected by A. veronii bv. sobria and exhibited high morbidity and mortality. Gross pathologic features and histology revealed a systemic infection characterized by the presence of abscesses and chronic granulomatous inflammation. Two clinical bacterial isolates (Aero NS and Aero PDB) were identified as A. veronii bv. sobria based on bacteriological characteristics and sequence analysis for 16S rRNA and gyrB genes. Infectivity tests in the form of intraperitoneal injection administration (Aero NS) and immersion in a bacterial suspension (Aero NS and Aero PDB) revealed that both isolates could cause clinical signs similar to those observed in the field and high mortality rate.

abstract = {A membrane bioreactor (MBR), accomplishing high nitrogen removal efficiencies, was evaluated under various landfill leachate concentrations (50, 75 and 100% v/v). Proteinous and carbohydrate extracellular polymeric substances (EPS) and soluble microbial product (SMP) were strongly correlated (p textbackslashtextless 0.01) with organic load, salinity and NH4+-N. Exceptionally high β-glucosidase activities (6700–10,100 U g−1) were determined during MBR operation with 50% v/v leachate, as a result of the low organic carbon availability that extendedly induced β-glucosidases to breakdown the least biodegradable organic fraction. Illumina sequencing revealed that candidate Saccharibacteria were dominant, independently of the leachate concentration applied, whereas other microbiota (21.2% of total reads) disappeared when undiluted leachate was used. Fungal taxa shifted from a Saccharomyces- to a newly-described Cryptomycota-based community with increasing leachate concentration. Indeed, this is the first report on the dominance of candidate Saccharibacteria and on the examination of their metabolic behavior in a bioreactor treating real wastewater. © 2017 Elsevier Ltd},

abstract = {Early life adversity may be critical for the brain structural plasticity that in turn would influence juvenile behaviour. To address this, we questioned whether early life environment has an impact on stress responses latter in life, using European sea bass, Dicentrarchus labrax, as a model organism. Unpredictable chronic low intensity stress (UCLIS), using a variety of moderate intensity stressors, was applied during two early ontogenetic stages, flexion or formation all fins. At juvenile stage, fish were exposed to acute stress and plasma cortisol, brain mRNA expression of corticosteroid receptors’ genes (gr1, gr2, mr) and brain cell proliferation (using BrdU immunohistochemistry) were determined in experimental and matched controls. UCLIS treatment specifically decreased brain gr1 expression in juveniles, but had no effect on the juvenile brain cell proliferation pattern within the major neurogenic zones studied of dorsal (Dm, Dld) and ventral (Vv) telencephalic, preoptic (NPO) areas, periventricular tectum gray zone (PGZ) and valvula cerebellum (VCe). In contrast, exposure to acute stress induced significant plasma cortisol rise, decreases of cerebral cell proliferation in juveniles, not previously exposed to UCLIS, but no effect detected on the expression levels of gr1, gr2 and mr in all groups of different early life history. Interestingly, juveniles with UCLIS history showed modified responses to acute stress, attenuating acute stress-induced cell proliferation decreases, indicating a long-lasting effect of early life treatment. Taken together, early life mild stress experience influences an acute stress plasticity end-point, cerebral cell proliferation, independently of the stress-axis activation, possibly leading to more effective coping styles. © 2016 Elsevier B.V.},

abstract = {The effects of rearing volume on on-growing European sea bass performance and stress parameters were investigated for the first time in a pilot aquaculture farm. Fish were held under the same initial stocking densities in triplicate net-pen cages of different sizes (1.4, 45 and 252 m3) for a period of 8 months. Results showed significant differences among the experimental groups in most parameters tested, with better performance in the two larger rearing volumes. In particular, growth rate showed a linear association with rearing volume, being 0.68 g day−1 for the large cage group, 0.56 g day−1 and 0.32 g day−1 for the medium and the small groups respectively. The feed conversion ratio and per cent survival (%) were also better in the large cage group. Fish reared in the small and medium-sized cages showed higher plasma cortisol concentrations than those reared in large cages, which showed low basal cortisol concentrations. Additionally, after an acute chasing stress challenge, fish in the large and small groups, but not the medium group, showed increased cortisol concentrations. Differences also occurred in the ratio of the expression of cortisol receptors, namely the mineralocorticoid (mr) and glucocorticoid receptors (gr). In specific, the ratio of mr to grmRNA expression in the liver was higher in fish reared in the small cages. These findings verify that experimental scale significantly affects experimental results and is a critical factor for the interpretation of results. © 2015 John Wiley & Sons Ltd},

Immunohistochemistry showed α-MSH positive cells in the pituitary pars intermedia in all stages examined. As development proceeds, α-MSH content gradually increases; mRNA levels of mc2r and mc4r remain low until first feeding where peak values are observed. Mc1r expression was constant during development, pomc mRNA levels remain low until the stage of flexion after which a significant increase is observed. At the stage of the formation of all fins, whole-body cortisol and α-MSH concentrations responded with peak values at 2 h post stress. Additionally, the stress challenge resulted in elevated transcript levels of pomc, mc2r and mc4r but not in mc1r, with a pattern characterized by peak values at 1 h post stress and a strong correlation with whole body α-MSH concentrations was found.

abstract = {The Mediterranean Sea is home to over 2/3 of the world's charter boat traffic and hosts an estimated 1.5 million recreational boats. Studies elsewhere have demonstrated marinas as important hubs for the stepping-stone transfer of non-indigenous species (NIS), but these unique anthropogenic, and typically artificial habitats have largely gone overlooked in the Mediterranean as sources of NIS hot-spots. From April 2015 to November 2016, 34 marinas were sampled across the following Mediterranean countries: Spain, France, Italy, Malta, Greece, Turkey and Cyprus to investigate the NIS presence and richness in the specialized hard substrate material of these marina habitats. All macroinvertebrate taxa were collected and identified. Additionally, fouling samples were collected from approximately 600 boat-hulls from 25 of these marinas to determine if boats host diverse NIS not present in the marina. Here, we present data revealing that Mediterranean marinas indeed act as major hubs for the transfer of marine NIS, and we also provide evidence that recreational boats act as effective vectors of spread. From this wide-ranging geographical study, we report here numerous new NIS records at the basin, subregional, country and locality level. At the basin level, we report three NIS new to the Mediterranean Sea (Achelia sawayai sensu lato, Aorides longimerus, Cymodoce aff. fuscina), and the re-appearance of two NIS previously known but currently considered extinct in the Mediterranean (Bemlos leptocheirus, Saccostrea glomerata).We also compellingly update the distributions of many NIS in theMediterranean Sea showing some recent spreading; we provide details for 11 new subregional records for NIS (Watersipora arcuata, Hydroides brachyacantha sensu lato and Saccostrea glomerata now present in theWesternMediterranean; Symplegma brakenhielmi, Stenothoe georgiana, Spirobranchus tertaceros sensu lato, Dendostrea folium sensu lato and Parasmittina egyptiaca now present in the Central Mediterranean, and W. arcuata, Bemlos leptocheirus and Dyspanopeus sayi in the Eastern Mediterranean). We also report 51 new NIS country records from recreational marinas: 12 for Malta, 10 for Cyprus, nine for Greece, six for Spain and France, five for Turkey and three for Italy, representing 32 species. Finally, we report 20 new NIS records (representing 17 species) found on recreational boat-hulls (mobile habitats), not yet found in the same marina, or in most cases, even the country. For each new NIS record, their native origin and global and Mediterranean distributions are provided, along with details of the new record. Additionally, taxonomic characters used for identification and photos of the specimens are also provided. These new NIS records should now be added to the relevant NIS databases compiled by several entities. Records of uncertain identity are also discussed, to assess the probability of valid non-indigenous status. © 2017 Ulman et al.},

abstract = {This contribution forms part of a series of collective articles published regularly in Mediterranean Marine Science that report on new biodiversity records from the Mediterranean basin. The current article presents 51 geographically distinct records for 21 taxa belonging to 6 Phyla, extending from the western Mediterranean to the Levantine. The new records, per country, are as follows: Spain: the cryptogenic calcareous sponge Paraleucilla magna is reported from a new location in the Alicante region. Algeria: the rare Atlanto-Mediterranean bivalve Cardium indicum is reported from Annaba. Tunisia: new distribution records for the Indo-Pacific lionfish Pterois miles from Zembra Island and Cape Bon. Italy: the ark clam Anadara transversa is reported from mussel cultures in the Gulf of Naples, while the amphipod Caprella scaura and the isopods Paracerceis sculpta and Paranthura japonica are reported as associated to the –also allochthonous–bryozoan Amathia verticillata in the Adriatic Sea; in the latter region, the cosmopolitan Atlantic tripletail Lobotes surinamensisis also reported, a rare finding for the Mediterranean. Slovenia: a new record of the non-indigenous nudibranch Polycera hedgpethi in the Adriatic. Greece: several new reports of the introduced scleractinian Oculina patagonica, the fangtooth moray Enchelycore anatina, the blunthead puffer Sphoeroides pachygaster (all Atlantic), and the lionfish Pterois miles (Indo-Pacific) suggest their ongoing establishment in the Aegean Sea; the deepest bathymetric record of the invasive alga Caulerpa cylindracea in the Mediterranean Sea is also registered in the Kyklades, at depths exceeding 70 m. Turkey: new distribution records for two non indigenous crustaceans, the blue crab Callinectes sapidus (Atlantic origin) and the moon crab Matuta victor (Indo-Pacific origin) from the Bay of Izmir and Antalya, respectively; in the latter region, the Red Sea goatfish Parupeneus forsskali, is also reported. Lebanon: an array of records of 5 alien and one native Mediterranean species is reported by citizen-scientists; the Pacific jellyfish Phyllorhiza punctata and the Indo-Pacific teleosteans Tylerius spinosissimus, Ostracion cubicus, and Lutjanus argentimaculatus are reported from the Lebanese coast, the latter notably being the second record for the species in the Mediterranean Sea since 1977; the native sand snake-eel Ophisurus serpens, rare in the eastern Mediterranean, is reported for the first time from Lebanon, this being its easternmost distribution range; finally, a substantial number of sightings of the lionfish Pterois miles further confirm the current establishment of this lessepsian species in the Levantine.},

abstract = {In marine fishes, the extent to which spatial patterns induced by selection remain stable across generations remains largely unknown. In the gilthead sea bream Sparus aurata, polymorphisms in the growth hormone (GH) and prolactin (Prl) genes can display high levels of differentiation between marine and lagoon habitats. These genotype-environment associations have been attributed to differential selection following larval settlement, but it remains unclear whether selective mortality during later juvenile stages further shapes genetic differences among habitats. We addressed this question by analysing differentiation patterns at GH and Prl markers together with a set of 21 putatively neutral microsatellite loci. We compared genetic variation of spring juveniles that had just settled in 3 ecologically different lagoons against older juveniles sampled from the same sites in autumn, at the onset of winter outmigration. In spring, genetic differentiation among lagoons was greater than expected from neutrality for both candidate gene markers. Surprisingly, this signal disappeared completely in the older juveniles, with no significant differentiation for either locus a few months later in autumn. We searched for signals of haplotype structure within GH and Prl genes using next-generation amplicon deep sequencing. Both genes contained 2 groups of haplotypes, but high similarities among groups indicated that signatures of selection, if any, had largely been erased by recombination. Our results are consistent with the view that differential selection operates during early juvenile life in sea bream and highlight the importance of temporal replication in studies of post-settlement selection in marine fish. © The authors, CNRS and TOTAL Foundation 2016.},

The exotrophic phase was divided into three distinct developmental stages (a) larval, from feeding onset up to 10 mm total length (TL); (b) metamorphosis, from 10 mm TL up to 24 mm TL; and (c) further juveniles. The majority of all ontogenic changes was expressed during the larval stage and integrated during the metamorphosis stage. The juvenile stage was characterized by developmental stability. The normal development of D. dentex was seriously affected by the rearing conditions applied during the early exotrophic phase. The two differently reared populations followed similar developmental patterns of general morphology, pigmentation and behaviour, but they presented high developmental plasticity where allometric growth was concerned. Rearing conditions influenced both the boundaries of the sequential stages (in 50% of the morphometric ratios) and the allometry coefficient of each morphometric character in the various developmental stages (in 80% of the characters). The results are discussed with respect to the ontogeny of the functional morphology under both ecological and aquaculture considerations.},

A combined mixture of poultry meat meal and feather meal was also tested at high inclusion levels of 75 and 100%. Finally, two lower grade poultry by-product meals produced for the Greek industry were tested at various levels for comparison. The diets were isocaloric containing 18 MJ/kg of gross energy, isonitrogenous (CP: 45%) and had a lipid content of 13% on an as fed basis. The experiment was carried out in a semiclosed rearing system and its duration was 84 days. The groups of fish fed 75 and 100% poultry meat meal showed a slight reduction in growth parameters compared to fish fed the control diet containing white fish meal but was not statistically significant (P textless 0.05). Similar results were obtained for the fish fed the poultry and feather mixture. Feed efficiency, protein and energy utilisation followed the same trends. One of the locally produced meals at substitution levels of up to 50% produced no significant reduction in growth of seabream (P textless 0.05). At the level of 75% of the protein, however, the material caused a severe decrease in growth performance, feed efficiency, protein efficiency ratio and apparent net protein utilisation. Inferior quality was also demonstrated by the other poultry meal available on the Greek market. Protein digestibility coefficients were measured for all diets and essential amino acid indices and chemical score values were calculated.},

The same diet formulation was used in all treatments containing fish meal LT, soybean meal and wheat flour as the main ingredients. Feeding levels were the same for all groups of fish and were close to satiation. The results obtained for fish growth and feed efficiency did not differ significantly among groups of fish for both species studied. Muscle, liver and kidney were analysed for AA content after frequent sampling of fish. Tissue ascorbate levels increased after feeding the ascorbate containing diets, the rate of increase was although higher for sea bream than for sea bass. Ascorbate levels in groups fed the fat coated diet were lower than those fed the diets containing phosphate esters, probably due to a higher destruction of this form during feed preparation and storage. AA levels in the tissues studied were different with muscle having the lowest and kidney the highest value. Ascorbate levels in fish fed the ascorbate free diet decreased significantly. No growth reduction or deficiency signs were observed.},

Here we have investigated the mechanisms of resistance to these two insecticides by studying cross-resistance, synergism, activity of detoxifying enzymes, and possible modifications of the target proteins. Resistance to pirimicarb was shown to be mainly due to a decreased sensitivity of the target acetylcholinesterase; this modification confered also, resistance to propoxur but not to methomyl and the two tested organophosphates (acephate and paraoxon). Endosulfan resistance was associated with a moderate level of resistance to dieldrin, and resistance to both insecticides was due, in part, to increased detoxification by glutathione S-transferases (GST). The endosulfan resistant strain displayed the same amino acid at position 302 of the Rdl gene (GABA receptor) as susceptible aphids (e.g. Ala), indicating that the Ala to Ser (or to Gly) mutation observed among dieldrin resistant strains of other insect species was not present.

abstract = {During the cultivation of marine fish larvae, unconsumed rotifers (Brachionus plicatilis) may reside in the tanks for several days and their nutritional value may become severely reduced. In order to quantify this process, body biomass and protein content per individual rotifer was measured during starvation at different temperatures (4-28°C) for a period of 5 to 7 days. Both well-fed rotifers and poorly-fed rotifers were used, in order to examine the effect of the nutritional status at the start of the experiment on the loss rates of biomass and protein. At high temperatures the carbon, nitrogen and amino acid content decreased exponentially with time. A large part of body biomass (40-50%) was lost during the first 4 days of starvation at 18-20°C. The rate of decrease was positively related to the temperature. Poorly-fed rotifers were more sensitive to starvation than well-fed rotifers, as their nitrogen content decreased at a higher rate. Starvation of rotifers may be prevented by addition of microalgae in concentrations of 1-2 mg C l-1. At 4-5°C, the carbon, nitrogen and amino acid content remained relatively stable. Rotifers may thus be stored for < 5 days at 4-5°C without a significant loss in their nutritional value.},

Sequence analysis consistently revealed the separation of the samples in two major groups: French mites differed from Japanese by 3.8-4.1% of the nucleotide divergence in COI sequences. These two groups also displayed distinct ITS2 consensus sequences (2.1% nucleotide divergence). A few variations, not affecting the diagnostic sites around the consensus sequence, were revealed among cloned copies of the same individual. Reciprocal crosses and backcrosses between one French and two Japanese populations disclosed strong reproductive incompatibility. However, fertile hybrid females were obtained, indicating the conspecificity of the tested mites. Despite the presence of Wolbachia in the French strain, but not in the Japanese ones, our crosses did not display the unidirectional incompatibility typically produced by this microorganism, but rather a bidirectional - although asymmetrical - incompatibility pattern. The post-zygotic incompatibilities in A. viennensis cannot be explained by the presence of Wolbachia but to some extent by mite genome divergence resulting from limited gene exchange between allopatric populations. Experiments of Wolbachia elimination by antibiotic treatment and subsequent crosses with cured strains are still needed to fully understand the reproductive incompatibility patterns in this mite species.},

abstract = {Diel rhythms in serum glucose, lactate, cholesterol, triglycerides and thyroid hormones were studied in red porgy, Pagrus pagrus, held under different photoperiod regimes (constant darkness - DD, 8L:16D,12L:12D), at a constant temperature (17.1-18.7 °C) and fed with commercial pellets, by means of a self-feeder. A clear diurnal rhythm in feeding activity, regardless of the photoperiod regime was demonstrated. All serum components showed significant diel rhythms, although they were not necessarily consistent or circadian in periodicity. As well as this, differences in the average values among the varying treatments were observed. Fish held under the 12L:12D protocol displayed significantly higher average T4, T3 and lactate levels during the day rather than at night. Maximum glucose values occurred 8-12 h after dawn and maximum lactate concentrations at 06:00 or 14:00 h. Diel variations in cholesterol were evident only in the DD group with peak values inversely correlated with the rhythm of food intake. Triglycerides displayed a similar pattern of changes. Significant diel fluctuations in T4 serum levels were observed only in fish exposed to the 12L:12D protocol, with peak values at dawn. A clear diurnal peak (10:00h) in T3 concentrations was observed in fish subjected to the 12L:12D regime, while fish exposed to the 8L:16D protocol showed two peaks: one in the photophase (10:00 h) and another in the scotophase (02:00 h). The light-dark alternation and the general activity rhythm of fish seem to be the main synchronizers of the diel rhythms observed in this study.},

Clearance rates were determined in short-term experiments either by measuring the decrease in concentration of live particles and plastic beads, or by measuring the radioactivity accumulated in animals that grazed 14C-labelled live particles. The maximum clearance rate of A.franciscana metanauplii increased during development and was measured at 50-63 μl ind.-1 h-1, 254 μl ind.-1 h-1 and 1.48-2.10 ml ind.-1 h-1 in 2-, 4- and 7-day-old metanauplii, respectively. A preference for particles with a diameter of 4-8 μm was observed at all three developmental stages. The ability of A. franciscana metanauplii to graze bacterial particles was also demonstrated, although the efficiency in grazing such small particles was low compared to microalgae (28, 20 and 9% of the maximum clearance rate in 2-, 4- and 7-day-old metanauplii, respectively). Electron microscopy showed that the inter-setular distance in antennae and thoracopods was 0.20 ± 0.07, 0.16 ± 0.05 and 0.18 ± 0.04 μm in 2-, 4- and 7-day-old metanauplii, respectively, and accordingly independent of stage.},

Oil- coated OA and OTC on feeds were greatly affected by leaching at 16 °C (losses of 55.5% and 42.5% for OA and OTC respectively) and 24 °C (32% for OA and 47% for OTC).

Increased water temperature induced a significant effect on the leaching of both drugs when mixed with the feed, but did not affect the loss of oil-coated drugs. There was a significant reduction in feed consumption of fish fed a diet with oil-coated OTC (90% and 92% at 16°C and 24°C respectively), whereas intake of feed containing oil-coated OA was only slightly affected (10% at 16 °C, 12% at 24 °C). The depressed palatability of feeds containing oil-coated OTC was overcome by mixing the drug with the diet. Both antibiotics were well digested by seabass (94% and 85% for OA and OTC respectively) at 24°C; however, more than one-third of each drug was recovered in the faeces at 16 °C (64% and 59% for OA and OTC respectively). The significance of these findings for the interaction between fish therapy and marine environment is stressed.},

The annual cycles of the nutrients phosphate and silicate compare guile well with the observed ranges of variability. This does not hold for ammonium and nitrate where the increased concentrations could be attributed to external inputs from the land. Nutrient budgets calculated from the model results indicate some competition between phytoplankton and bacteria for nutrients, a common characteristic of lagoons. To further develop the model, an adaptation of the phytoplankton submodel to represent benthic primary production, as well as the modification of the benthic nutrient model to cope with anoxic events are suggested.},

Typhlodromus pyri and Phytoseiulus persimilis. As expected, the 5.8S gene (148 base pairs) is markedly conserved and displays little variation in between genera comparisons. ITS1 and ITS2 show contrasting patterns: while the ITS2 is short (80-89 bp) and shows little variation, the ITS1 is longer (303-404 bp) and is very variable in sequence. This fact compromises reliable nucleotide homologies when comparing the genera. The comparison of ITS1 sequence similarity at the species level might be useful for species identification, however, the value of ITS in taxonomic studies does not extend to the level of the family. The intraspecific variations of ITS were investigated in three species: N. californicus, N. fallacis and E. concordis. The first species has identical ITS1 sequences and the last two display low polymorphism (2 nucleotide substitutions). The ITS2 and 5.8S sequences were identical in all three subspecies comparisons.},

abstract = {Systematics of the European species of the genus textitBarbus is controversial for decades because of the relative similarity in general morphology between species. The use of more objective and precise characters, such as osteology, has given improved results. However, in the absence of a thorough morphological analysis of the group, genetic markers providing a promising method for obtaining more accurate phylogenies.On the basis of distinct ecological and morphological characters, the European textitBarbus taxa have been clustered in two groups : a fluvio-lacustrinetextittextless/itextgreaterand a rheophilic or strictly riverine one. These two groups (or ecophenotypes) were recognised in different parts of Europe, and formed, either a species assemblage (textlessitextgreaterBarbus barbus group) or a polytypic species (textitBarbus meridionalis). The implicit idea is that species of to the same group belong, to the same phylogenetic lineage (clade) and are the result of the same transcontinental colonisation event.The analysis, using allozyme markers, of 10 taxa of the genus textitBarbus from France, Italy, Greece, the Czech Republic and Slovakia, showed that the taxa thought to belong to the fluvio-lacustrine and the rheophilic groups are not monophyletic. We mention some alternative hypotheses, including the possibility that the allozyme markers may be inadequate. The results suggest that probably in each sub-region, the founding taxon has diverged independently to form species of two different ecophenotypes ; one occupying the upstream rivers and another found in the lowland rivers. Accordingly, textitBarbus species groups represent clusters of morphologically convergent taxa living in equivalent biotopes},

The second internal transcribed spacer (ITS2) of rDNA and a fragment in the mtDNA gene coding for Cytochrome Oxidase I (COI), were PCR-amplified and sequenced in samples of various geographical origins distributed worldwide. The 15 COI haplotypes found fell into two major phylogenetic lineages differing by an average of 5% nucleotide divergence. Samples from the Mediterranean basin were represented in both lineages, and showed no phylogeographical structure. The other samples, from temperate regions of the northern hemisphere, were clustered in one of the lineages and displayed little variation, indicating a recent colonization of this region. In contrast, no variation at all was found at the ITS2 in this species. We sequenced both COI and ITS2 in four other species of the genus Tetranychus and found that, despite the absence of intraspecific polymorphism, ITS appears to evolve 2.5 times faster than COI. We argue that rDNA homogeneity over the species range of T. urticae results from the high colonization potential of this species, preventing long-term differentiation. Preliminary data on two other mite species (Amphitetranychus viennensis Zacher and Mononychellus progresivus Doreste) with stricter ecological requirements and more restricted colonization potential revealed substantial and concordant geographical differentiation for both ITS2 and COI.},

Circulating gonadotropin II (GtH II), 17,20β-dihydroxy- 4-pregnen-3-one (17,20β-P), and 17,20β,21-trihydroxy-4-pregnen-3-one (17,20β,21-P) remained low and unchanged in nonmaturing females, while 17β- estradiol (E2) and testosterone (T) declined throughout postvitellogenesis. Plasma thyroxine (T4) declined significantly in mid-April, while triiodothyronine (T3) increased in mid-May. The only female that ovulated spontaneously had markedly different E2, T, and T3 profiles during postvitellogenesis, and had a surge in plasma GtH II during final oocyte maturation (FOM). The lack of a GtH II surge is presumably responsible for the absence of FOM, but earlier, and as of yet unknown, endocrine disruptions during postvitellogenesis may determine the female's ability to undergo FOM. Treatment of females with a gonadotropin-releasing hormone agonist (GnRHa)- delivery system induced FOM and ovulation within 3 and 10 days, respectively, and resulted in the production of fertile eggs. Plasma GtH II increased continually after GnRHa implantation, even in the presence of declining GnRHa plasma levels. Plasma E2 increased first and peaked prior to FOM, whereas T peaked at the peripheral germinal vesicle (GV) stage. Plasma 17,20β-P and 17,20β,21-P increased dramatically at the GV breakdown (GVBD) stage. Plasma T4 was unaffected by the GnRHa treatment, whereas T3 decreased after GnRHa implantation and remained low throughout FOM. Based on the observed hormonal profiles, FOM can be separated into an early phase (lipid-droplet coalescence, GV migration) associated with E2 and T elevations, and a late phase (yolk-globule coalescence, GVBD) associated with 17,20β-P and 17,20β,21-P elevation.},

In two experiments, males were injected intramuscularly with either microspheres or pellets containing gonadotrophin- releasing hormone agonist (GnRHa). Blood was sampled at 2- to 5-day intervals. Individual blood plasma specimens were assayed for testosterone, 5β-reduced, 3α-hydroxy ('5β,3α') steroids and sulphated 17,20βdihydroxy ('17,20β') steroids. Pooled plasma samples were also assayed for free and sulphated 17,20β-dihydroxy-4-pregnen-3-one, free 11-ketotestosterone, and glucuronidated testosterone and 11-ketotestosterone. Plasma concentrations of all steroids were significantly elevated by GnRHa from 2 to 5 days onwards following treatment. The most marked changes occurred in the concentrations of the sulphated 17,20β steroids, which comprised approximately equal amounts of 5β-pregnane-3α, 17,20β-triol 20-sulphate (3α,17,20β-P-5β-S) and 5β-pregnane-3β,17,20β-triol 20-sulphate, rising from ca. 1 to 30-80 ng/ml in the first and from ca. 8 to 80 ng/ml in the second experiment.

The plasma of these fish contained excessive amounts of 5β,3α- immunoreactive material between 10 and 25 days. This material was identified as 3α,17,21-trihydroxy-5β-pregnan-20-one 21-sulphate (a metabolite of 11- deoxycortisol). All previous studies have indicated that when plasma concentrations of this steroid are high, so are those of 3α,17,20β-P-5β- S. This is the first indication that these steroids are regulated independently. In a third experiment, milt fluidity and production were assessed at 10, 15, and 25 days following GnRHa implantation. Milt volume and fluidity were significantly enhanced by the GnRHa treatment.},

abstract = {Plasma profiles of reproductive and thyroid hormones were studied in captive striped bass Morone saxatilis during an 11-wk period encompassing the spawning season, and the effect of a sustained-release gonadotropin-releasing hormone agonist (GnRHa)-delivery system (GnRHa-implant) on milt production was evaluated. The highest percentage of spermiating fish was observed between mid-April and mid-May, and mean total expressible milt ranged from 3.5 to 6.0 mL/kg. Plasma gonadotropin II (GtH II) increased significantly, though inconsistently, during the spermiation period, whereas testosterone and 11-ketotestosterone levels declined continually. Plasma 17,20β-dihydroxy-4-pregnen-3-one and 17,20β,21-dihydroxy-4-pregnen-3-one remained low and unchanged during the peak of the spermiation period, while thyroid hormones were high and fluctuated without exhibiting a trend consistent with spermiation. The observed endocrine profiles suggest that captivity can diminish plasma GtH II and triiodothyronine levels in striped bass. Transfer of spermiating males from large holding tanks to small spawning tanks reduced total expressible milt after 14 d, but treatment with a GnRHa-implant restored milt volume, presumably due to the prolonged elevation of plasma GnRHa and GtH II induced by the GnRHa-implant. Also, treatment with the GnRHa-implant induced a two-to four-fold elevation of expressible milt for at least 20 d compared to control fish, while resulting in only a 5 to 15% decrease in sperm density. It appears that captivity and hatchery operations can diminish milt production in striped bass, and that GnRHa-delivery systems, via sustained elevation of plasma GtH II, can induce long-term enhancement in milt volume without affecting sperm density greatly.},

The mortality rate was higher in the oceanic population (2.55 for males, 2.00 for females) than in the fjords (1.15 for males, 0.97 for females). Fish from the Norwegian Sea population occupied a depth with higher light levels, which may have contributed to the higher mortality through increased visibility to predators. Differences in growth, condition and gonad weight indicated different resource levels caused by different population densities. Recruitment was weak in many fjords in 1994, but not in the Norwegian Sea. It is suggested that wind-generated advection may affect recruitment in fjords on the western coast of Norway.},

Here we investigate the presence of microsatellite sequences in the genome of two mite species, Tetranychus urticae and Amblyseius fallacis, based on screening of both mite genomic libraries and Southern blots of these mites that we compare to two vertebrates. No signal with GT15 or a faint smear with CT10 were obtained in Southern analysis for the two mites, whereas both probes strongly bound with vertebrate DNA. Genomic libraries constructed in plasmid and lambda vectors were probed and only two CT microsatellites were isolated for T. urticae. Among eight trinucleotides probes tested, the strongest hybridization signal was detected for T. urticae with CAT and TGA probes. These two classes of repeats were also the most represented in genomic library screenings. However, only sequences with short numbers of units could be detected (< CAT4 or TGA9). Congruency of Southern analysis and screening of partial genomic libraries indicates an under-representation of microsatellite sequences in the two mite genomes. The potential of the scarce repetitive DNA isolated from mites to serve as population genetics markers is discussed on the basis of preliminary assessment of their polymorphism.},

abstract = {The degradation of permanent semi-natural vegetation and the resulting acceleration of soil degradation and erosion processes constitute major elements of land degradation in the Mediterranean basin. These elements are triggered by human activities rather than climatic conditions. The Greek island of Crete represents a characteristic case of land degradation resulting from hundreds of years of intensive grazing and fires. Since Greece joined the European Communities in 1981, grazing in mountainous regions has greatly increased due to subsidies that became available through the Common Agricultural Policy. Within a European Research Project on the use of satellite remote sensing for monitoring environmental change in Mediterranean ecosystems (DeMon-2: An Integrated Approach to Assess and Monitor Desertification Processes in the Mediterranean Basin), we have initiated a study to monitor the impact of increased grazing pressure on two mountainous ecosystems in Crete. The approach is based on describing surface conditions and vegetation cover over time with a long-term series of earth observation satellites.},

Analysis of these data has allowed a first assessment of the status of floating marine pollution in the region. DDPH measurements showed a mean concentration of 0.145 μg/l of chrysene equivalents (n = 24). Tar and plastics concentrations were in the range of 1 - 4280 and 0 - 1160 μg/m2, respectively. Mean pelagic tar concentration was 318 μg/m2, more than two times higher than what was reported for the area in previous studies.

A gradual lengthening of the period of annulus formation was observed, from the younger to the older fish. The annulus formation in fish older than 2+ was less synchronized, due to the aquaculture conditions. Scales were more accurate than otoliths in annuli formation. A high percentage of missing or additional opaque zones were observed on otoliths of older fish. These irregularities were related to fish maturation and/or farming conditions.
