Food Subsidies Reduce Livestock Depredations by a Recovering Carnivore
Animal Conservation, EarlyView.Diversionary feeding—providing food caches to divert predators away from preying on livestock—is a strategy to reduce depredations by Mexican gray wolves but has not been evaluated for its effectiveness. We used data from the Mexican wolf recovery program from 2014‐2021 to evaluate whether diversionary feeding reduced livestock depredations by wolf ...

Deadly Lifeworlds Meet Palliative Politics: Struggle in Circulation
Antipode, EarlyView.Abstract This paper locates acute and ongoing crises of coloniality and ecology within struggles over circulation that are anchored in infrastructure. If infrastructure organises movement—including its constraint in carceral forms—then it is also a linchpin for materialising distinct regimes of motion (Nail 2020a; Marx in Motion: A New Materialist ...

A phylogenomic perspective on interspecific competition
Ecology Letters, 2023AbstractEvolutionary processes may have substantial impacts on community assembly, but evidence for phylogenetic relatedness as a determinant of interspecific interaction strength remains mixed. In this perspective, we consider a possible role for discordance between gene trees and species trees in the interpretation of phylogenetic signal in studies ...

Speciation, Adaptation and Interspecific Competition [PDF]
Oikos, 1984 Apres avoir considere les concepts d'espece et de speciation on envisage les effets possibles de la competition au niveau de l'historique de la speciation et de la post-speciation de l'espece.

Spatial heterogeneity and interspecific competition
Theoretical Population Biology, 1982A model of two competing species is presented in which each species is able to disperse over a single spatial axis. The spatial axis is composed of two intervals with different carrying capacities. We ask the question: If species one is alone and at population dynamic equilibrium, then when can species two successfully invade when rare?

Selection and Interspecific Competition
1977Other organisms constitute a component of the environment to which animals respond by natural selection. Among the different kinds of interspecific interactions, competition for common resources is attributed an important role in the evolution of the single species and for the structure of biological communities.

Interspecific competition in metapopulations
Biological Journal of the Linnean Society, 1991The assumptions and predictions of metapopulation models for competing species are discussed in relation to empirical studies of colonization and extinction in metapopulations. In three species of Daphnia in rockpools, interspecific competition increased local extinction rates, while no effects on colonization rates were detected.

Interspecific Competition and Exploitation
Journal of the Fisheries Research Board of Canada, 1963The consequences of exploitation of either or both of a pair of competing species are examined using the Lotka-Volterra equations. The removal of a fixed proportion of a population on an instantaneous basis shifts the equilibrium population sizes for both the exploited species and its competitor.

Interspecific Competition and Speciation in Endoparasitoids
Evolutionary Biology, 2012Ecological speciation occurs when inherent reproductive barriers to gene flow evolve between populations as a result of divergent natural selection. Frequency dependent effects associated with intraspecific resource competition are thought to be one important source of divergent selection facilitating ecological speciation.
