New Polymorphic Microsatellite Loci for the Zebra MusselDreissena polymorpha(Pallas, 1771), a Common Bioindicator

2011

ABSTRACT To investigate the influence of environmental pollution on the population genetics of Dreissena polymorpha, we developed five new polymorphic micro satellite loci for the zebra mussel. This mussel is widely distributed and is a common bioindicator in the field of ecotoxicology. The amplification of the microsatellite loci was tested on a single population of 24 individuals. In this population, the number of alleles per locus ranged from 3–14, and the observed heterozygosity ranged from 0.545–0.909 (mean, 0.772). All loci followed Hardy-Weinberg expectations, suggesting no evidence for null alleles. There was no significant genetic linkage disequilibrium, neither between the aforeme…

Does an ant-dispersed plant, Viola reichenbachiana, suffer from reduced seed dispersal under inundation disturbances?

2008

Many plant species use ants as seed dispersers. This dispersal mode is considered to be susceptible to disturbances, but the effect of natural, small-scale disturbances is still unknown. We investigated how small-scale disturbances due to inundation affect seed dispersal in Viola reichenbachiana, a dominant myrmecochorous herb in riparian forests. Inundation disturbances were high in depressions and low on hillocks of the forest floor. We found that V reichenbachiana was similarly abundant at highly and less disturbed sites, contrary to other, non ant-dispersed species. We also found that the motivation of ants to disperse seeds was higher at highly disturbed sites. Nevertheless, the number…

The genus Troglophilus Krauss, 1879 (Orthoptera: Rhaphidophoridae) in the west Balkans

2011

We present a revision of the genus Troglophilus in the western part of the Balkan Peninsula based on morphological and genetic analysis, and provide distribution data for the species. The results of these analyses reduced the number of the known taxa within the genus Troglophilus in this area to five valid species: Troglophilus cavicola (Kollar, 1833), Troglophilus neglectusKrauss, 1879, Troglophilus ovuliformisKarny, 1907, Troglophilus brevicauda Chopard, 1934, and Troglophilus lazaropolensis Karaman, 1958. A new species Troglophilus zorae sp. nov. is described and Troglophilus neglectus serbicus Maran, 1958, Troglophilus neglectus vlasinensis Maran, 1958, Troglophilus bukoviki Karaman, 19…
