Interspecific competition models and resource inequality between individuals [PDF]

Royal Society Open Science
Most classical discrete-time population models of interspecific competition have emerged as population-level phenomenological models with no evident basis at the individual level.

Maternal effects and the outcome of interspecific competition [PDF]

Ecology and Evolution, 2021
Abstract Maternal environmental effects create lagged population responses to past environments. Although they are ubiquitous and vary in expression across taxa, it remains unclear if and how their presence alters competitive interactions in ecological communities. Here, we use a discrete‐time competition model to simulate how maternal effects alter

Multidimensional primate niche space sheds light on interspecific competition in primate evolution [PDF]

Communications Biology
Characterising how the totality of primate diversity is distributed across the order, and how it evolved, is challenging because diversity in individual traits often show opposing phylogenetic patterns.

Neighborhood Diversity Promotes Tree Growth in a Secondary Forest: The Interplay of Intraspecific Competition, Interspecific Competition, and Spatial Scale [PDF]

Plants
Understanding the biodiversity–productivity relationship (BPR) is crucial for biodiversity conservation and ecosystem management. While it is known that diversity enhances forest productivity, the underlying mechanisms at the local neighborhood level ...

The Interspecific Competition Between Larvae of Aedes aegypti and Major African Malaria Vectors in a Semi-Field System in Tanzania [PDF]

Insects
Interspecific competition between mosquito larvae may affects adult vectorial capacity, potentially reducing disease transmission. It also influences population dynamics, and cannibalistic and predatory behaviors.

Does past evolutionary history under different mating regimes influence the demographic dynamics of interspecific competition? [PDF]

Ecology and Evolution, 2019
Interspecific interactions are contingent upon organism phenotypes, and thus phenotypic evolution can modify interspecific interactions and affect ecological dynamics.

Evolutionary disarmament in interspecific competition [PDF]

Proceedings of the Royal Society of London. Series B: Biological Sciences, 2001
Competitive asymmetry, which is the advantage of having a larger body or stronger weaponry than a contestant, drives spectacular evolutionary arms races in intraspecific competition. Similar asymmetries are well documented in interspecific competition, yet they seldom lead to exaggerated traits.

What Drives Life-History Variation in the Livebearing Fish Poeciliopsis prolifica? An Assessment of Multiple Putative Selective Agents

Frontiers in Ecology and Evolution, 2021
Life-history traits are directly linked to fitness, and therefore, can be highly adaptive. Livebearers have been used as models for understanding the evolution of life histories due to their wide diversity in these traits.

Spatial Aspects of Interspecific Competition [PDF]

Theoretical Population Biology, 1998
Using several variants of a stochastic spatial model introduced by Silvertown et al., we investigate the effect of spatial distribution of individuals on the outcome of competition. First, we prove rigorously that if one species has a competitive advantage over each of the others, then eventually it takes over all the sites in the system.

The effect of microplastics on the interspecific competition of Daphnia

Environmental Pollution, 2022
Microplastic pollution is currently one of the most intensely studied ecological issues. Numerous studies have estimated the distribution and concentration of microplastics in various environments and determine how they affect their inhabitants. Much less effort has been place on assessing the possible effects of microplastics on interactions between ...
