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 …

Ecological character displacement, mostly seen as increased differences of size in sympatry
between closely‐related or similar species, is a focal hypothesis assuming that species too …

Fish have proven to be model organisms for the study of animal personalities, and a rich
literature documents consistent interindividual behavioral differences in a variety of species …

Predators are increasingly recognized as key elements in food webs because of their ability
to link the fluxes of nutrients and energy between spatially separated food chains. However …

The transition to piscivory is a crucial ontogenetic niche shift for many primarily piscivorous
fishes. An early transition to piscivory may increase growth, decrease mortality, and …

Studies on resource polymorphism have mainly been considered at the end stage of
ontogeny, whereas many species undergo diet changes as they grow. We conducted a field …

Trade‐offs in foraging efficiency leading to divergent natural selection between and within
populations exploiting different resources are thought to be a primary cause of trophic …

Although there is mounting evidence that speciation can occur under sympatric conditions,
unambiguous examples from nature are rare and it is almost always possible to propose …

While numerous studies have been conducted on the ecology and evolution of phenotypic
plasticity, to really understand plasticity we need to expose organisms to different …

As lakeshores are developed, property owners often thin the riparian forest and remove
older logs or fallen limbs from the adjacent littoral zone. This practice alters fish habitat and …
