Sigma CB concentrations were highest in adipose tissue and ranged from 775 to 893, 39 to 261 and 47 to 178 mu g/kg wet wt in loggerhead (Caretta carretta), green (Chelonia mydas) and leatherback (Dermochelys coriacea) turtles, respectively. Omnivorous loggerhead turtles had the highest organochlorine contaminant (OC) concentrations in all tissues sampled. It is thought that dietary preferences were likely to be the main differentiating factor among species. Decreasing lipid contaminant burdens with turtle size were observed in green turtles, most likely attributable to a change in diet with age. Principal component analysis of data from loggerhead and green turtles indicated that there were also pattern differences between species, confirming bioaccumulation differences.

The potential effect of certain topographic characteristics (e.g. area, bottom depth, and the degree of land enclosure) on the spatial structure of the fish was studied in different geographic subareas (i.e. how topography affects the organization of fish into clusters of schools). Parameters calculated by geostatistical techniques were used as descriptors of the spatial organization. The results indicate the significant effect of area and land enclosure on the spatial structures of both species, suggesting that environmental spatial heterogeneity attributable to coastal topography affected the way fish schools were organized into aggregations. In summer, the spatial structure of sardine was more heterogeneous in subareas with increased land enclosure, whereas the spatial structure of anchovy was not significantly related to any of the area characteristics examined. In winter, the spatial structure of both species was more heterogeneous in subareas with increased enclosure and in small rather than larger subareas. The findings are discussed in terms of the species' response to their environment. (c) 2006 International Council for the Exploration of the Sea. Published by Elsevier Ltd. All rights reserved.

The techniques were evaluated based on their efficiency to forecast and their ability to utilise auxiliary environmental information. Applying a "stepwise modelling" technique, namely by adding stepwise predictors and comparing the quality of fit, certain inferences concerning the importance of the predictors were made.The ARIMA models predicted the test data very precisely (high R-2), especially if the target time series contained a strong autoregressive character, after they were first differenced to obtain stationarity (R-2 > 0.96). The disadvantage of the ARIMA, as with most statistical models, is their assumption that the relationships and system parameters remain the same across the observation and forecasting periods.The influence of temperature on catches was mainly investigated by applying neural models, which predicted the monthly landings with high precision (R-2 = 0.89), even when incorporating in the model exclusively monthly SST descriptors. Similarly, ANN models of annual landings containing monthly mean temperatures provided high precision (R-2 = 0.87) and valuable inference concerning the possible effect of the SST in certain months.Bayesian dynamic models also provided a high precision (R-2 = 0.96). They combined the information of both environmental and landing time series, namely the monthly mean temperatures and the monthly seasonality of the landings. The impact factors estimated from the model have the form of time series representing the temperature effect.The results reveal that both the monthly and the annual landings can be predicted and that the Bayesian model is the best performer overall, characterised by a higher number of stable forecasts, and forecasts with higher precision and accuracy, than the other methods. It is evident, from application of the "stepwise modelling" technique, that the incorporation of temperature descriptors can significantly improve the model performance. (c) 2006 Elsevier B.V.

In this study, we generated mitochondrial DNA COI barcodes using adult specimens of all 22 species of the hoverfly genus Merodon (Diptera, Syrphidae) occurring on Lesvos island (Greece). The generated COI barcodes could well discriminate between all Merodon taxa of Lesvos, except for M. loewi and M. papillus that shared the same haplotype, despite their clear morphological differences. In addition, the barcodes revealed two cases of hitherto unknown morphologically cryptic species close to M. avidus and M. nigritarsis, respectively. Because only few successful rearings of immature stages of Merodon hoverflies are available, the larval host plant remains unknown for these phytophagous taxa. The obtained COI barcode library for the Merodon spp. of Lesvos will constitute a tool to link any unknown immature stages with already known species, and thus provide important life-history information and promise for ecological studies.

Multivariate analyses of nine call parameters demonstrate the existence of three distinct groups of populations which differ in the degree of temperature dependence of four parameters, and specifically in the number of pulses/pulse group and pulse groups/ call. Since discriminant functions distinguish among these groups with very low rates of false classification and since the degree of differentiation between the groups is similar to that towards R. perezi, taxonomic consequences are indicated.The lake frog populations near the Caspian Sea (CIS) inhabit the terra typica restricta and, thus, represent R. ridibunda. The lake frogs of Armenia (CIS) and of Thrace (Greece) also belong to this species. The mating call of R. ridibunda consists of 19 pulses/pulse group and of 7 pulse groups/call on the average. Finally, the southwestern form, inhabiting Greece and southern Yugoslavia, is named R. balcanica sp. n. Its mating call is characterized by 29 pulses/pulse group and 4 pulse groups/call on the average. Finally, the southeastern form ranging from Turkey to Egypt is named R. levantina sp. n. In this species the number of pulses/pulse group averages 11 and that of pulse groups/call 10. According to the phylogenetic analysis of the character states using parsimony, we conclude that R. perezi and R. levantina are sibling species forming an outgroup to the European sibling species R. ridibunda and R. balcanica.

The populations of Thrace and of the island of Samothraki form a group giving the same type of mating call, whereas the mating call of the other populations differs in the degree of temperature dependence of four parameters, and specifically in the number of pulses/pulse group and pulse groups/call. Discriminant functions distinguish even single call series with a probability of 97 %, intermediate mating calls are absent, and there is a significant, but slight differentiation of external morphological characters. These results have strong taxonomic implications. We conclude that the lake frogs of Greece comprise two species.The mating call of the lake frogs from Thrace resembles in all parameters that of the Rana ridibunda in the terra typica restricta (Guryev CIS). Accordingly, the lake frogs of eastern Greece belong to R. ridibunda. The mating call of these lake frogs consists of 20 pulses/pulse group and of 7 pulse groups/call on the average. Most of Greece is inhabited by the second taxon, Rana balcanica sp. n. Its mating call is characterized by 27 pulses/pulse group and 4 pulse groups/call on the average.The two species in Greece do not differ with respect to coloration and size, but several standardized indices vary significantly: body length/digitus primus length; body length/callus internus length; body length/snout-eye distance; body length/tympanum diameter; tibia length/callus internus length; maximal head width/snout-eye distance.

The aim of this study was to examine the phylogenetic relationships among these honey bee populations, to investigate the existence of gene flow as a result of migratory beekeeping and commercial breeding, and to find out if these subspecies can be discriminated. Seven and eight different haplotypes were revealed for the COI and ND5 gene segments respectively, while the combined data set consisted of twelve different haplotypes. Among the two DNA segments studied, the highest genetic divergence values were observed in COI. In both genes the highest divergence value was among A. m. ligustica colonies and all others. All the phylogenetic trees constructed by Maximum Parsimony, Neighbour-Joining and Bayesian Inference analyses exhibited exactly the same topology for COI and ND5 separately, as well as for the concatenated data set; A. m. ligustica forms the most distinct clade. Our study presents the first comprehensive sequencing analysis of A. mellifera subspecies occurring in Greece and it is the first time that sequencing data from ND5 mtDNA gene segment have been obtained at the population level.

In this study we analysed the phylogeny within the genus Dolichopoda using parts of the mitochondrial cytochrome oxidase I and 16S ribosomal genes, and explored biogeographic patterns through a dispersal-vicariance analysis (DIVA). Phylogenetic analyses grouped the 15 species into the four geographically restricted main lineages corresponding to the Caucasus, Greece, the Pyrenees and Italy, respectively. The species occur largely in allopatry. The Caucasian and Greek species were basal in the phylogeny, as was the clade including the nine Italian species, which grouped into two major lineages, one mainly including species from western Italian coastal regions and islands, and the other including species with a predominantly inland distribution. Thus it seems likely that there have been two main immigrations into Italy followed by multiple consecutive speciation events. The DIVA analysis supported the assumption of an east-west migration route, and indicated that there have been four major dispersal events. Since the statistical support for the basal node connecting D. remyi and D. hussoni with the west Mediterranean species is low, alternative interpretations for the colonization of the Mediterranean, namely parallel colonization of the main areas of the current Dolichopoda distribution, i.e. the Caucasus, Greece, Italy, and the Pyrenees is also possible. Particular emphasis was put on the D. geniculata-laetitiae species complex. D. geniculata included several recently diverged lineages and constitutes a paraphyletic species complex, also embracing the closely related D. laetitiae.

Sampling was carried out in early summer during a period of 4 years (2003-2006). Taxonomic composition and abundance presented high variability in space that remained relatively constant among years. Tow depth and indicators of trophic conditions in the upper water column (i.e., zooplankton displacement volume, fluorescence) explained significantly the structure of larval assemblages during all surveys. The northern continental shelf (Thracian and Strymonikos shelo, where a large amount of enriched, low salinity BSW is retained, was dominated by larvae of epipelagic species, mainly anchovy (Engraulis encrasicolus). Interannual changes in horizontal extension of the BSW seemed to match closely observed changes in the distribution of anchovy larvae. Mesopelagic fish larvae were particularly abundant beyond the continental shelf (over the North Aegean Trough) where a strong frontal structure is created between the low salinity waters of BSW origin and the high salinity waters of the Aegean Sea. Larvae of certain mesopelagic species (e.g., Ceratoscopelus maderensis) may occasionally be transported inshore when the prevailing current meanders towards the coast or feeds anticyclonic gyres over the continental shelf.

Spain is the only European country where the cultivar Compa CB derived from the event Bt176 was commercially grown, from 1998 to 2005. The large decrease of the titer of the toxin in this cultivar at later growth stages represented the worst-case scenario for resistance development of MCB, since larvae of the second and third generations were exposed to sublethal concentrations of Cry1Ab toxin. Our data revealed that the variation in susceptibility to Cry1Ab for the MCB Spanish field populations analyzed in the three years was very low, with LC(50) values fluctuating between 12 and 30 ngCry1Ab/cm(2), regardless of the region of origin, the type of maize (Bt or non-Bt) and the year. Furthermore, no significant differences were found when comparisons were made with a laboratory population (LC(50) values: 18-26 ng Cry1Ab/cm(2)) or with field populations from Greece (Bt-free areas), which displayed LC(50) values ranging between 22 and 27 ng Cry1Ab/cm(2). Standardizing bioassay protocols proved to be essential for obtaining comparable results. These findings suggest that resistant MCB populations did not evolve in those Spanish maize areas where Compa CB was largely cultivated for eight years, contradicting the expected rapid development of resistance under these unfavourable conditions. Additionally, our results can be used as baseline indices in post-market resistance monitoring programs if Bt maize is introduced in Greece. Further studies should continue, since the insights gained from a resistance monitoring program may help to enhance the durability of Bt maize. (C) 2011 Elsevier Ltd. All rights reserved.

The part of sea bream production is about 60% of the total production of these species. During the last decade, a spectacular increase in both the number of farms and their production, accompanied by a substantial price decrease and modification of their structure and functioning, has been recorded. These changes resulted in the maintenance in cages of large individuals (more than 500 g) of gilthead sea bream which are potential spawners. The study, based on both the maturity stage and the decrease in individual mean weights during the reproductive period of the species, confirmed reproduction in cages. In parallel, during the last 5 years a remarkable increase (about 80%) in sea bream landings from the fish trap fisheries of the Messolonghi-Etoliko lagoon, which is a typical nursery for the species, was recorded. The increase was accompanied by a decrease both in price and mean size of the O-group individuals. The possible influence of the rearing activities in the area, the density-dependent mechanisms and the negative impacts of this unintentional enhancement of the traditional lagoon fisheries of the area are discussed.

Silurus glanis is the largest-bodied freshwater fish of Europe and is historically known to take a wide range of food items including human remains. As a result of its piscivorous diet, S. glanis is assumed to be an invasive fish species presenting a risk to native species and ecosystems. To assess the potential risks of S. glanis introductions, published and 'grey' literature on the species' environmental biology (but not aquaculture) was extensively reviewed. Silurus glanis appears well adapted to, and sufficiently robust for, translocation and introduction outside its native range. A nest-guarding species, S. glanis is long-lived, rather sedentary and produces relatively fewer eggs per body mass than many fish species. It appears to establish relatively easily, although more so in warmer (i.e. Mediterranean) than in northern countries (e.g. Belgium, UK). Telemetry data suggest that dispersal is linked to flooding/spates and human translation of the species. Potential impacts in its introduced European range include disease transmission, hybridization (in Greece with native endemic Aristotle's catfish [Silurus aristotelis]), predation on native species and possibly the modification of food web structure in some regions. However, S. glanis has also been reported (France, Spain, Turkmenistan) to prey intensively on other non-native species and in its native Germany to be a poor biomanipulation tool for top-down predation of zooplanktivorous fishes. As such, S. glanis is unlikely to exert trophic pressure on native fishes except in circumstances where other human impacts are already in force. In summary, virtually all aspects of the environmental biology of introduced S. glanis require further study to determine the potential risks of its introduction to novel environments.

In the samples of M. nicotianae examined, M. persicae-like ff genotypes were rare and heterozygotes (sf) were in large excess, even in samples from Greece where M. nicotianae has a regular holocycle (i.e., annual sexual reproduction). In North America, where M. nicotianae is probably entirely anholocyclic, samples of both red and green colour morphs of this species were found to be heterozygous for GOT-1. The enzyme difference can thus provide a means of distinguishing most individual specimens, including trapped alatae, of M. persicae and M. nicotianae. The anholocyclic taxon M. antirrhinii appears to be a fixed heterozygote for GOT-1 and thus resembles most M. nicotianae, but can be distinguished electrophoretically from both M. persicae and M. nicotianae by its distinctive pattern of esterases.

Experimental subjects were acclimated to a salinity of 6ppt. Through gradual increases, individuals of P. stymphalicus were able to tolerate salinities up to 12-13ppt, while individuals of V. letourneuxi survived in normal seawater (33ppt) and had an upper lethal limit of ca. 46ppt. Valencia letourneuxi, one of two species of the Mediterranean family Valenciidae, is one of the least euryhaline of secondary division teleost fishes. Its distribution matches that of P. stymphalicus, suggesting that its dispersion was not by way of marine waters but by mechanisms used by primary and primary-like freshwater fishes. We reconsider the primary and secondary division and primary-like categories and propose that five basic groups be recognized: primary, primary-like, secondary low salt tolerant, secondary high salt tolerant, and peripheral.

Cysts of parthenogenetic Artemia strains collected from the Citros and M. Embolon saltworks in Northern Greece are evaluated for their potential use in aquaculture. The following characterizations were performed: cyst and naupliar biometrics, cyst hatching characteristics, fatty acid profile of the nauplii, caloric content of nauplii stored at 25 °C and in a refrigerator (4–8 °C). The above evaluation reveals that the two Artemia strains studied exhibit good qualities for use in aquaculture, especially in culturing fresh-water species. The biometrical analysis of cysts, nauplii and adults shows a high degree of similarity with other parthenogenetic strains from various geographical sources, but especially with tetraploid Artemia from Spain. The Greek Artemia strains cannot be considered as ‘sources’ for aquacultural uses unless proper management of the saltworks is assured.

The genetic polymorphism of twelve enzyme systems in two parthenogenetic tetraploid Artemia populations from N. Greece has been studied, using starch gel electrophoresis. The genetic distance within and among the two Greek populations was calculated. The high degree of genetic identity between the populations indicates that they belong to the same species. Each is composed of electrophoretically identifiable clones; the fitness of these clones under different environmental conditions is discussed.

The cosmopolitan species, Porcellionides pruinosus (Brandt, 1833), exhibited a geographical variation of its morphological features and its reproduction pattern. In fact, some Tunisian populations had a seasonal reproductive period and other ones showed a reproductive activity. A phenetic analysis has been performed to compare populations belonging to P. pruinosus from different geographical localities. For this, nineteen quantitative characters in 800 specimens of P. pruinosus issued from nine populations located in the North, the Centre, and the South of Tunisia, and one population from Athens (Greece) were studied. These populations were characterized by different reproductive behaviours. The populations of Tabarka, Korba, and Tamerza showed reproductive activity, whereas those of Garat Nâam, Raccada, Sahline, Gafsa, Rdayef, Gabès, and Athens exhibited a seasonal reproductive period. The variability of the first three axes of the principal components analysis (PCA) and their significance showed an intraspecific variability structure. The graphical representation of the population's dispersion generated by the two first axes (63.55% of the total variability) revealed a great heterogeneity among females of the different populations of P. pruinosus. The Garat Nâam population was set apart from the other ones by its cephalic width and length and also by its apophysis length. Furthermore, cephalic and uropod length separated the Garat Nâam and Tabarka populations. The dendrogram, based on Euclidean coordinates, confirms an isolation of the populations of Tabarka and Garat Nâam, exhibiting respectively reproductive activity and seasonal reproduction. However, the other populations do not show any relationship with the reproduction behaviour. They were clustered in two groups. The first one is represented by the populations of the Southeast and the West of Tunisia. The second pooled the populations of the Northeast and the Centre of Tunisia with the population of Athens (Greece). Phenetic analysis of Tunisian populations exhibits an important heterogeneity, which is worth noting. Thus, we need to complete and deepen this study by genetic analysis and crossbreeding tests in order to define the taxonomic status of these populations. To cite this article: M.S. Achouri, F.
