Consumer‐resource theory predicts dynamic transitions between outcomes of interspecific interactions

open access: closedEcology Letters, 2009
Ecology Letters(2009) 12: 1357–1366AbstractInteractions between two populations are often defined by their interaction outcomes; that is, the positive, neutral, or negative effects of species on one another. Yet, signs of outcomes are not absolute, but vary with the biotic and abiotic contexts of interactions.

DEFINING AND MEASURING THE IMPACT OF DYNAMIC TRAITS ON INTERSPECIFIC INTERACTIONS

open access: closedEcology, 2007
Trait- and density-mediated indirect effects describe different pathways by which indirect interactions in food webs are propagated from one species to another, through changes in intermediate species. A series of articles in Ecology has progressively altered the original definitions of "trait-mediated" to the point where understanding is being impeded.

Role of interspecific competition among predators and group size : A dynamical approach

open access: closedJournal of Interdisciplinary Mathematics, 2023
Living in a group benefit all living beings for their survival and fulfilling needs. This paper proposes and analyzes a prey-predator system with the interspecific death and functional response Hassell-Varley. First, we discuss the existing stationary points of the system and their permanence.
