Ecosphere, 2020 Intraspecific diversity can have as strong an effect on communities and ecosystems as more well‐studied effects of species diversity. Intraspecific variation in prey body size may have particularly strong effects on populations by influencing the outcome

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

Spatial Ecology of Livestock Protection Dogs, Sheep, and Pampas Foxes in Agroecosystem of Central Argentina [PDF]
AnimalsLivestock protection dogs (LPDs) are specifically bred to protect livestock, such as sheep, from predators. These dogs’ primary defense mechanisms include directional actions that deter predators but no attack.

Evaluation of the Effect of Ecological Factors on Cannibalism in Pelophylax bedriagae (Pallas, 1771) (Amphibia: Anura) [PDF]
Iranian Journal of Animal Biosystematics, 2023 Marsh frog, Pelophylax bedriagae tadpoles habituate in temporary wetlands where intraspecific aggression has been observed. In this study, we examined the independent and interactive effects of predator cues, water level and density on head width size ...

Variable Intraspecific Space Use Supports Optimality in an Apex Predator [PDF]
Scientific Reports, 2021 Abstract Within optimality theory, an animal’s home range can be considered a fitness-driven attempt to obtain resources for survival and reproduction while minimizing costs. We assessed whether brown bears (Ursus arctos) in two island populations maximized resource patches within home ranges (Resource Dispersion Hypothesis [RDH]) or occupied ...
