Competition plays a central role in the maintenance of biodiversity. A backbone of classic
niche theory is that local coexistence of competitors is favoured by the contraction or …

Neotropical streams stand as one of the most biodiverse aquatic ecosystems in the world.
The extremely high biodiversity of these ecosystems was generated and modified by several …

Although neglected by classic niche theory, individual variation is now recognized as a
prevalent phenomenon in nature with evolutionary and ecological relevance. Recent theory …

Many generalist species consist of specialised individuals that use different resources. This
within‐population niche variation can stabilise population and community dynamics …

Ecological opportunity (ie the diversity of available resources) has a pivotal role in sha**
niche variation and trophic specialisation of animals. However, ecological opportunity can …

We examine temporal (seasonal) and spatial (habitat) effects on consumers' diet, trophic
position, trophic niche, and food-web topology in a subtropical oligotrophic wetland to …

Coexistence of ecomorphologically similar species in diverse Neotropical ecosystems has
been a focus of long-term debate among ecologists and evolutionary biologists. Such …

The effects of environmental seasonality on food web structure have been notoriously
understudied in empirical ecology. Here, we focus on seasonal changes in one key attribute …

Individual diet specialization (IS) has important community‐and population‐level
implications and its ecological drivers are actively investigated. Here, to test the hypothesis …

The persistence of diverse communities and functioning ecosystems under increasing
anthropogenic pressure relies on food web rewiring and the ability of animals to expand or …
