Interspecific Competition and Vertical Niche Partitioning in Fiji’s Forest Birds

open access: yesDiversity, 2022
Charles Darwin proposed his ‘principle of divergence’ to account for changes in traits that could promote speciation and coexistence of diverse forms through occupation of different niches to reduce interspecific competition.

Spatial Aspects of Interspecific Competition [PDF]

open access: yesTheoretical 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.

Effects of Intra- and Interspecific Plant Density on Rhizosphere Bacterial Communities

open access: yesFrontiers in Microbiology, 2020
There have been very few studies on the effects of plant competition on the rhizosphere bacterial community. To investigate the impacts of intra- and interspecific plant competition, we analyzed the responses of rhizosphere bacterial communities to plant

Shift in competitive ability mediated by soil biota in an invasive plant

open access: yesEcology and Evolution, 2021
Understanding the shifts in competitive ability and its driving forces is key to predict the future of plant invasion. Changes in the competition environment and soil biota are two selective forces that impose remarkable influences on competitive ability.

Quantifying and Disentangling the Competition Effect of a Weed Community in a Long-Term Biennial Cereal-Legume Rotation

open access: yesAgronomy, 2023
Weeds are a permanent constraint on crop productivity in agriculture. Due to the importance of the effect of weeds on the crop, there has been great interest in establishing the competitive ability of each species to optimize its control.

Host competence, interspecific competition and vector preference interact to determine the vector-borne infection ecology

open access: yesFrontiers in Ecology and Evolution, 2022
Understanding how ecological interactions affect vector-borne disease dynamics is crucial in the context of rapid biodiversity loss and increased emerging vector-borne diseases.

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

open access: yesFrontiers 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.

Contrasting impacts of competition on ecological and social trait evolution in songbirds. [PDF]

open access: yesPLoS Biology, 2018
Competition between closely related species has long been viewed as a powerful selective force that drives trait diversification, thereby generating phenotypic diversity over macroevolutionary timescales.

The Role of Competition in Structuring Primate Communities under Different Productivity Regimes in the Amazon.

open access: yesPLoS ONE, 2015
The factors responsible for the formation of Amazonian primate communities are not well understood. Here we investigated the influence of interspecific competition in the assembly of these communities, specifically whether they follow an assembly rule ...
