ANALYSIS OF DYNAMICS IN A GENERAL INTRAGUILD PREDATION MODEL WITH INTRASPECIFIC COMPETITION

Journal of Applied Analysis and Computation, 2019
Summary: This paper is devoted to studying the dynamical properties of a general intraguild predation model with intraspecific competition. We first investigate the stability of all possible equilibria in relation to the ecological parameters, and then study the long time behavior of the solution. Moreover, we provide a detailed analysis of dynamics of

Consequences of intraspecific predation: A stage structured population model approach

1991
By differential equations with time delayed arguments, a predator-prey system is described where only older animals are predacious but hunt, besides a prey population, also juveniles of their own species. Increasing intraspecific predation first reduces the amplitudes of predator-prey oscillations; a further increase then causes damping.

A Survey of Intraspecific Predation among Reptiles and Amphibians

Journal of Herpetology, 1985
Numerous investigations, citing occurrences of cannibalism and/or oophagy in over 100 species of reptiles and amphibians, were reviewed with particular emphasis on predator/prey characteristics, environmental determinants, and evolutionary significance.

A predator-prey model with satiation and intraspecific competition

Ecological Modelling, 1978
Abstract We present a new predator-prey model where, except for the prey growth, assumed to be logistic, we endeavor to give some behavioral justification to all elements of the predator-prey interaction. The functional response takes account of predator satiation and predator competition. It is supported by some experimental evidence. We distinguish

Intraspecific Predation among Northwestern Crows

The Wilson Bulletin, 2004
Abstract Cannibalism is uncommon in birds, and instances of adults killing and eating other adults are especially rare. Cases of intraspecific predation among passerines constitute a very small percentage of published reports, and many of the cases are based on circumstantial evidence.
