Species shifting their ranges under climate change are a conservation dilemma. Range-shifters may be threatened by in historic range. However, range-shifters likely to generalist opportunists, which could mean they harm aspects of biodiversity new ecosystems. Therefore, we need approaches rapidly assess how integrate into the community historically resident species. The small red-eyed damselfly...
