Ontogenetic dietary shifts (ODSs), the changes in diet utilisation occurring over the life span
of an individual consumer, are widespread in the animal kingdom. Understanding ODSs …

Omnivory, feeding at more than one trophic level, is a prevalent feature of freshwater
ecosystems. Understanding where and when omnivory is important, its relevance for …

Fish are an important source of eicosapentaenoic acid (EPA) and docosahexaenoic acid
(DHA) for birds, mammals and humans. In aquatic food webs, these highly unsaturated fatty …

Antarctic biodiversity is affected by seasonal sea-ice dynamics driving basal resource
availability. To (1) determine the role of intraspecific dietary variability in structuring benthic …

Aquatic ecosystems support size structured food webs, wherein predator‐prey body sizes
span orders of magnitude. As such, these food webs are replete with extremely generalized …

Recent advances in molecular techniques allow us to resolve the diet of unstudied taxa.
Odonates are potentially important top‐down regulators of many insects. Yet, to date, our …

The inherently multidimensional nature of the niche has not yet been integrated into the
investigation of individual niche specialization within populations. We propose a framework …

To understand food web dynamics, knowledge about factors influencing trophic interactions
is fundamental. Using stomach content analysis, we investigated size-dependent predator …

Lake charr, Salvelinus namaycush, ecological and phenotypic diversity within and among
populations was reviewed from empirical and conceptual perspectives. The species is …

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