Abstract:Anthropogenic environmental changes continue to threaten species globally. On the one hand, anthropogenic movement of species has caused unintentional hybridisation, which has contributed to species declines. On the other hand (more recently), hybridisation has been viewed as a way to increase the evolutionary potential of species vulnerable to rapid environmental change. However, the benefits of mixing genetically divergent lineages do not come without risks to individual fitness and the long-term viability o… Show more
