Cross system subsidies of energy and materials can be a substantial fraction of food web
fluxes in ecosystems, especially when autochthonous production is strongly limited by light …

Abstract Theory indicates that competing species coexist in a community when intraspecific
competition is stronger than interspecific competition. When body size determines the …

The elemental composition of animals, or their organismal stoichiometry, is thought to
constrain their contribution to nutrient recycling, their interactions with other animals, and …

Mechanistic models of population, community and ecosystem dynamics require the
mathematical description of trophic interactions in the form of functional response equations …

The evolutionary divergence of sexual signals is often important during the formation of new
animal species, but our understanding of the origin of signal diversity is limited [1, 2] …

The effect of consumers on their resources has been demonstrated in many systems but is
often confounded by trophic interactions with other consumers. Consumers may also have …

Background: Life-history theory predicts that populations experiencing different patterns of
age-or size-specific mortality will evolve divergent life histories. Higher mortality can also …

Terrestrial invertebrates are important subsidies to fish diets, though their seasonal
dynamics and importance to tropical stream consumers are particularly understudied. In this …
