英文摘要: The dietary generalist-specialist distinction plays a pivotal role in theoretical and applied ecology, conservation, invasion biology, and evolution and yet the concept remains poorly characterised. Diets, which are commonly used to define niche breadth, are almost exclusively considered in terms of foods, with little regard for the mixtures of nutrients and other compounds they contain. We use nutritional geometry (NG) to integrate nutrition with food-level approaches to the dietary niche and illustrate the application of our framework in the important context of invasion biology. We use an example that involves a model with four hypothetical nonexclusive scenarios. We additionally show how this approach can provide fresh theoretical insight into the ways nutrition and food choices impact trait evolution and trophic interactions. The dietary generalist-specialist distinction remains poorly characterised.Diets are almost exclusively considered in terms of foods eaten or their energy content rather than mixtures of the nutrients and other compounds they contain.We use the framework of nutritional geometry to develop a multi-nutrient approach to the dietary niche that provides fresh theoretical insights into generalism.Our nutritional approach can help to unify the roles of cognition, behaviour, and physiology with food choices in several fields.We consider the application of our multidimensional framework to invasion biology. © 2016 Elsevier Ltd.
