Predicting the impacts of non-native species remains a challenge. As populations of a species are genetically and phenotypically variable, the impact of non-native species on local taxa could crucially depend on population-specific traits and adaptations of both native and non-native species. Bitterling fishes are brood parasites of unionid mussels and unionid mussels produce larvae that parasi...

In the last two decades foreign-born share of New Zealand’s population has risen far faster than in other rich countries, raising questions about impacts on native-born population. We apply spatial econometric models to a three-wave panel 1851 census area units examine higher shares home ownership rates for native-born. A standard deviation is associated with one-sixth lower rate Much impact in...

Invasive species may establish in communities because they are better competitors than natives, but in order to remain community dominants, the competitive advantage of invasive species must be persistent. Native species that are not extirpated when highly invasive species are introduced are likely to compete with invaders. When population sizes and genetic diversity of native species are large...

RNA-sequencing is a new method of transcriptome characterization of organisms. Based on identity and relatedness, there are large genetic variations among different cattle breeds. The goal of the current study was to sequence the transcriptome of Guilan native cow and compare with available reference genome using RNA-sequencing method. Blood samples were collected from 14 Guilan native cows and...

The introduction of non-native species into new habitats poses a major threat to native populations. Of particular interest, though often overlooked, are introductions of populations that are not fully reproductively isolated from native individuals and can hybridize with them. To address this important topic we used different approaches in a multi-pronged study, combining the effects of mate c...

Species introductions to new habitats can cause a decline in the population size of competing native species and consequently also in their genetic diversity. We are interested in why these adverse effects are weak in some cases whereas in others the native species declines to the point of extinction. While the introduction rate and the growth rate of the introduced species in the new environme...
