We examined 662 gilthead sea bream Sparus aurata from wild samples of the species in the Aegean and Ionian Seas, using 20 EST‐linked microsatellite markers, in three multiplex panels, as well as seven anonymous loci. Most of the markers were revealed to be highly polymorphic. We found low genetic differentiation between the sampling stations/areas with total F ST 0.002 ( P S. aurata as well as of other aquaculture species with...

Aim We compared the power of different nuclear markers to investigate genetic structure of southern Balkan wild boar. We distinguished between historic events, such as isolation in different refugia during glacial periods, from recent demographic processes, such as naturally occurring expansions. Location Southern Balkans/Greece. Methods We sampled 555 wild boars from 20 different locations in southern Balkans/Greece. All indi...

Aim We focus on the biogeographical role of the Balkan Peninsula as a glacial refugium and source of northward post‐glacial dispersal for many European taxa. Specifically, we analysed the genetic structure and variation of wild boar ( Sus scrofa ) samples primarily from Greece, a region that has repeatedly served as a glacial refugium within the Balkan Peninsula. Location Continental Greece, the Aegean island of Samos and Bulg...

Egg identification in plankton samples is usually needed for purposes of stock assessment. Until recently, only morphological characters were used for identifying the eggs of different fish species. Late developmental stages are easily distinguishable due to pigmentation as well as egg and oil globule size range. However, for early stages, these characteristics are difficult to be discriminated and may overlap with other speci...

Aim Two species of the brine shrimp, namely Artemia franciscana Kellogg and A. persimilis Piccinelli and Prosdocimi, inhabit Chile. Most studies so far have shown that A. franciscana is the most widely distributed species in Chile, with A. persimilis present only in Chilean Patagonia. In general, there is good agreement between morphological and genetic comparisons of Chilean populations with respect to species discrimination....
