Mass migration of locusts is an economically devastating and poorly understood
phenomenon. Locust mass migration often follows rapid population growth because …

Cannibalism is an important factor in biology and ecology of many species of insects and
mites. The structure and dynamics of populations of predators used in biological control …

We describe for the first time the feeding ecology of the Pacific horned frog (Ceratophrys
stolzmanni), as inferred through gastrointestinal tract content analysis and behavioural …

Insects engage in cannibalism, a behaviour in which they devour members of their own
species. This paper brings together current knowledge on the mechanisms, functions, and …

A coupled pair of first order nonlinear discrete hierarchical age-structured models are
applied to study two modes of intraspecific competitions; scramble and contest. The study …

Abstract. A hierarchical size-structured population model is considered in which the birth,
death, and growth rates are functions of certain weighted integrals of population density …

The dynamics of asymmetric dispersion between two patches, where the local populations
are structured into m-age classes, are considered. The population in one of the patches is …
