Genome analysis of the monoclonal marbled crayfish reveals genetic separation over a short evolutionary timescale
The marbled crayfish (Procambarus virginalis) represents a very recently evolved parthenogenetic freshwater crayfish species that has invaded diverse habitats in Europe and in Madagascar. However, population genetic analyses have been hindered by the homogeneous genetic structure of the population and the lack of suitable tools for data analysis. We have used whole-genome sequencing to characterize reference specimens from various known wild populations. In parallel, we established a whole-genome sequencing data analysis pipeline for the population genetic analysis of nearly monoclonal genomes. Our results provide evidence for systematic genetic differences between geographically separated …
The distribution patterns, risk and potential effect of non-indigenous fish species of Hungarian waters
Translocation and introduction of non-indigenous species might be considered as one of the least reversible human induced changes in nature. The background factors of a successful biological invasion are diverse; and the complete eradication of established invasive species seems practically impossible. The aim of our presentation is to (1) revise the trends and spreading mechanisms of non-indigenous species; (2) assess the potential ecological risk of new species in the catchment basin of a shallow lake (Lake Balaton, Hungary) and (3) to analyze the local and regional factors affecting the distribution patterns of gibel carp (Carassius gibelio), an effective invasive species of the region, …
