Species interactions, as predators, prey, competitors or parasites, underpin the science of ecology. Understanding and quantifying these interactions, whether through analyses of existing data or the results of new fieldwork, often requires complex research approaches to tackle important issues, including responses to climate change, issues of wildlife health and increasing generalist predator populations.

Continuing influences of introduced hedgehogs Erinaceus europaeus as a predator of wader (Charadrii) eggs four decades after their release on the Outer Hebrides, Scotland
Non-native predators can cause major declines or even localised extinctions in prey populations across the globe, especially on islands. The removal of non-native predators can, therefore, be a...
