Climate change is creating the opportunity for various species to undertake range expansion, both geographically and elevationally. There has been relatively little research into the ecological effects of these climate-driven range expansions on predators, particularly when the new species to a comm

Estimates of species richness, while useful and common to many subdisciplines of biology, are problematic in their reliance on adequate sampling effort. How much sampling is required for an accurate estimate of species richness, and what levels of sampling will render communities comparable? This st
