Three measures of divergence, estimated at nine putatively neutral microsatellite markers, 14 quantitative traits, and seven quantitative trait loci (QTL) were compared in eight populations of the three-spined stickleback (Gasterosteus aculeatus L.) living in the Scheldt river basin (Belgium). Lowland estuarine and polder populations were polymorphic for(More)
Illegal, Unreported and Unregulated fishing has had a major role in the overexploitation of global fish populations. In response, international regulations have been imposed and many fisheries have been 'eco-certified' by consumer organizations, but methods for independent control of catch certificates and eco-labels are urgently needed. Here we show that,(More)
Aquatic organisms living in a range of photic environments require specific mechanisms to tune their visual pigments. Maximum absorbance (lambda(max)) of retinal rods in populations of the marine demersal sand goby, (Pomatoschistus minutus; Gobiidae, Teleostei) correlates with the local optic environment. It has been shown that this is not regulated through(More)
UNLABELLED PREMISE OF THE STUDY Nine polymorphic and 12 monomorphic microsatellite loci (simple sequence repeats [SSRs]) were isolated and characterized for the gynodioecious grassland perennial Saxifraga granulata. • METHODS AND RESULTS Based on genomic screening of leaf material of four individuals from four populations, a total of 21 microsatellite(More)
The burbot, Lota lota (Teleostei: Gadidae), has a holarctic distribution, with one subspecies (Lota lota lota) living in the lakes and rivers of the Palaearctic and northwestern North America and the other (Lota lota maculosa) living in the Nearctic (except the northwest). We analysed nine microsatellite loci and the mitochondrial DNA control region of 350(More)
In this study we used Roche’s 454 sequencing to develop genetic markers for Coenagrion scitulum, a Mediterranean damselfly currently expanding its range northward. With a modest amount of sequencing we detected 6,318 potential microsatellite markers and 832 putative single nucleotide polymorphisms (SNPs). From the potential microsatellite markers we(More)
