Average values of population heterozygosity were very high, even approaching values reported for marine fishes, possibly due to stable population sizes and the prolonged undisturbed conditions prevailing in the lakes that represent the native distribution of S. aristotelis. The success of an attempt to introduce the species into a new environment was also evaluated. No loss of genetic variability in the introduced population was detected. Additionally, assignment tests and trees based on genetic distances among individuals indicated the low differentiation of the translocated population from its donor population, and, differentiated the two autochthonous populations successfully. Comparisons with previous allozyme and mitochondrial RFLP studies were also made and showed that results on relative levels of genetic variability among populations were in good agreement among all methods. However, microsatellite analysis exhibited higher power of statistical tests for differentiation among population samples compared to allozymes. {\textcopyright} 2002 Ifremer/CNRS/Inra/IRD/Cemagref/E?ditions scientifiques et me?dicales Elsevier SAS.

RFLP analysis of four regions of mitochondrial DNA (cytochrome b, D-loop, ND-5/6) amplified by PCR was used. Ten and nine haplotypes were found in S. glanis and S. aristotelis, respectively. No haplotype was shared between the two species. Significant geographical substructuring was observed in the distribution of haplotypes, with most populations possessing private haplotypes. These haplotypes can serve as genetic {\textquoteright}tags{\textquoteright} and therefore warrant protection. Haplotype diversity was very low for all Greek S. glanis populations, possibly because the small size and large annual fluctuations of Greek inland waters do not support large fish populations. Nucleotide divergence was in the range of 0.00-0.52\% among S. glanis populations, and 0.00-0.11\% among S. aristotelis populations. Historical factors such as glaciations could account for these low values. The value of 6.75\% sequence divergence of the two species refutes the classification of the two species in different genera, as proposed by some authors. This study constitutes the first attempt, based on mitochondrial molecular data, to address the complicated evolutionary history of the two species which belong to the widely distributed and economically important Siluridae family.}, keywords = {genetic variation, mtDNA, phylogeny, Silurus aristotelis, Silurus glanis}, author = {Triantafyllidis, A. and Theodoros J.

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. {\textcopyright} Springer-Verlag 2005.}, keywords = {Rotifera}, author = {Papakostas, S. and Triantafyllidis, A. and Kappas, I. and Theodoros J.

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.

As the result of a first screening of temporary inland water habitats, Branchinella spinosa is here recorded for the first time in Greece. This finding extends the circum-Mediterranean part of its vast distribution. The species was collected from a shallow astatic coastal salt-marsh that is mainly fed by rainwater, where it coexists but rarely co-occurs with Artemia parthenogenetica. Branchinella spinosa is only the fourth anostracan species currently known from Greece. The poor knowledge of anostracan richness and abundance is mainly due to limited sampling efforts in this area. As temporary aquatic habitats are threatened by several anthropogenic activities, especially agriculture and land clearing for urbanisation and tourism, there is an urgent necessity for further monitoring and protection of these precious habitats.

An apomictic clone of the tetraploid parthenogenetic Artemia population from M. Embolon (Thessaloniki, Greece) was assayed for 10 reproductive and life span characteristics under laboratory conditions (in various salinity and temperature regimes). Salinity was proved to have significant impact on the majority of the characters used in this study. Discriminant function analysis gave an overall prediction of 97.32\% over the three salinities (50, 80 and 120 ppt). The temperature of 30\ \°C seemed to be an extreme one affecting significantly nearly all of the studied variables. The overall prediction according to the discriminant analysis was 94.69\% among the three temperatures (22, 26 and 30\ \°C). The clone performed best at 80 ppt and 22\ \°C. The data presented in this study may generate useful suggestions to investigate the potentiality of using a single genetic lineage in order to visualize the effects of different environmental cues on a specific clone.
