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 …

Mass‐specific standard metabolic rate (SMR, or maintenance metabolism) varies greatly
among individuals. Metabolism is particularly sensitive to variation in food consumption and …

The dynamics of ecological systems include a bewildering number of biotic interactions that
unfold over a vast range of spatial scales. Here, employing simple and general empirical …

We develop a model for somatic growth in fishes that explicitly allows for the energy demand
imposed by reproduction. We show that the von Bertalanffy (VB) equation provides a good …

We measured concentrations of essential fatty acids (EFAs) in four size categories of
planktonic organisms—seston (10–64 µm), microzooplankton (100–200 µm) …

There is a pressing need to understand how ecosystems will respond to climate change. To
date, no long-term empirical studies have confirmed that fish populations exhibit adaptive …

Les teneurs en mercure augmentent généralement en fonction de l'âge et de la taille chez
les poisons. Bien qu'un certain nombre d'hypothèses aient été invoquées pour expliquer ces …

Abstract In the western United States, the ability of non‐native lake trout (Salvelinus
namaycush) to attain large sizes,> 18 kg under favorable conditions, fueled the popularity of …

The life history of an organism is the series of chronological events that it experiences in
order to survive, grow, mature, reproduce, and recruit to perpetuate the species. The genetic …

Background In lake ecosystems, predatory fish can move and forage across both nearshore
and offshore habitats. This coupling of sub-habitats, which is important in stabilizing lake …
