Scientific Reports, 2021 Intraspecies violence, including lethal interactions, is a relatively common phenomenon in mammals. Contrarily, interspecies violence has mainly been investigated in the context of predation and received most research attention in carnivores.

Predator-prey Dynamics with Intraspecific Competition and an Allee Effect in the Predator Population
Letters in Biomathematics, 2017 The study of the Allee effect on the stability of equilibria of predator-prey systems is of recent interest to mathematicians, ecologists, and conservationists. Many theoretical models that include the Allee effect result in an unstable coexistence equilibrium. However, empirical evidence suggests that predator–prey systems exhibiting density-dependent

Frontiers in Ecology and Evolution, 2021 Despite their significance for paleobiological interpretations, bite marks have been rarely reported in non-mammalian therapsids (NMT). Here we describe, for the first time, the occurrence of a tooth embedded in the snout of a gorgonopsian.

Context-dependent interactive effects of non-lethal predation on larvae impact adult longevity and body composition. [PDF]
PLoS ONE, 2018 Predation impacts development, behavior and morphology of prey species thereby shaping their abundances, distribution and community structure. Non-lethal threat of predation, specifically, can have a strong influence on prey lifehistory characteristics ...

Boundary Value Problems, 2022 Abstract In this paper we consider a prey-predator model with prey refuge and intraspecific competition between predators using the Crowley-Martin functional response and investigate the dynamic characteristics of spatial and non-spatial prey-predator systems with each analytical and numerical approach.

Intraspecific predator interference promotes biodiversity in ecosystems
eLifeExplaining biodiversity is a fundamental issue in ecology. A long-standing puzzle lies in the paradox of the plankton: many species of plankton feeding on a limited variety of resources coexist, apparently flouting the competitive exclusion principle (CEP), which holds that the number of predator (consumer) species cannot exceed that of the resources ...

Sociobiology, 2016 The aim of this study was to verify the disappearance of eggs and larvae from the nests of the Mischocyttarus (Monogynoecus) montei, especially in autumn and winter, and at the same time, to discuss about the cannibalism as the main reason for survival ...

Predator cannibalism can shift prey community composition toward dominance by small prey species
Ecology and Evolution, 2022 Cannibalism among predators is a key intraspecific interaction affecting their density and foraging behavior, eventually modifying the strength of predation on heterospecific prey.

Review of inter and intraspecific predation by shorebirds
Ornis Fennica, 2020 Predation is often the most important driver of breeding productivity and population dynamics in birds, with an increasing impact in the currently rapidly changing world. Despite decades of intensive research, our understanding of trophic interactions and food webs is still limited.

Examining intraspecific multiple predator effects across shifting predator sex ratios [PDF]
Basic and Applied Ecology, 2020 Predator-predator interactions, or “multiple predator effects” (MPEs), are pervasive in the structuring of communities and complicate predictive quantifications of ecosystem dynamics. The nature of MPEs is also context-dependent, manifesting differently among species, prey densities and habitat structures.
