Primers for 18 microsatellite loci originally isolated from whiting (Merlangius merlangus, n = 6), stickleback (Gasterosteus aculeatus, n = 5) and cod (Gadus morhua, n = 7) were tested across a panel of diverse fish species, representing the three principal superclasses and most principal superorders of fish, to examine conservation of microsatellite(More)
We demonstrate significant population structuring on an extremely small spatial scale between adjacent demes of a Lake Malawi haplochromine cichlid species of the mbuna group, Pseudotropheus callainos, separated by only 35 m of habitat discontinuity. This substantiates further the notion that intralacustrine allopatric divergence may help to explain the(More)
Recent studies have suggested that size homoplasy is a prevalent feature of microsatellites and is expected to increase with time of divergence among populations and taxa. In this study, we performed sequence analysis of alleles from a complex microsatellite locus (Pzeb4, initially isolated from Pseudotropheus (Maylandia) zebra) from 1 midwater-feeding and(More)
To test the hypothesis of parallel speciation by sexual selection, we examined length variation at six microsatellite loci of samples from four sites of four to six putative species belonging to two subgenera of rocky shore mbuna cichlids from Lake Malawi. Almost all fixation indices were significantly different from zero, suggesting that there is presently(More)
Polymorphism at six microsatellite loci was used to study genetic variability and population structure in six geographically distant natural populations of European hake (Merluccius merluccius L.). Four hundred and eighty-three individuals were sampled from Trondheimsfjord in Norway, the Celtic Sea, the southern Bay of Biscay, Faro off Portugal, the(More)
Polymorphism at five microsatellite loci were screened to determine the genetic variability and the temporal stability of population structure in natural populations of European hake (Merluccius merluccius, L.) within the Bay of Biscay. In addition, the control region (900 bp) and two protein coding genes (ATPase, subunits 6 and 8, 842 bp and a partial(More)
The genetic structure of a free-living tagged population of European wild rabbits (Oryctolagus cuniculus) was investigated for two consecutive years (1990 and 1991) using 10 polymorphic microsatellite loci. A specific social behaviour, the formation of stable breeding groups, influenced the genetic structure of the population. These breeding groups were(More)
