Niche Partitioning Increases Resource Exploitation by Diverse Communities [PDF]

Science, 2008
Classical ecological theory suggests that the coexistence of consumer species is fostered by resource-use differences, leading to greater resource use in communities with more species. However, explicit empirical support for this idea is lacking, because resource use by species is generally confounded with other species-specific attributes. We overcame

A unifying framework for quantifying and comparing n‐dimensional hypervolumes

Methods in Ecology and Evolution, 2021
The quantification of Hutchinson's n‐dimensional hypervolume has enabled substantial progress in community ecology, species niche analysis and beyond. However, most existing methods do not support a partitioning of the different components of hypervolume.

Diet Metabarcoding Reveals Extensive Dietary Overlap between Two Benthic Stream Fishes (Zingel asper and Cottus gobio) and Provides Insights into Their Coexistence

Diversity, 2022
Niche partitioning studies are essential to understand the mechanisms that allow ecologically similar species to coexist. The Rhone streber (Zingel asper) and the European bullhead (Cottus gobio) are both benthic riverine fishes that consume ...

A novel multi-objective evolutionary algorithm based on space partitioning [PDF]

, 2019
To design an e ective multi-objective optimization evolutionary algorithms (MOEA), we need to address the following issues: 1) the sensitivity to the shape of true Pareto front (PF) on decomposition-based MOEAs; 2) the loss of diversity due to paying so ...

Decomposing the Causes for Niche Differentiation Between Species Using Hypervolumes

Frontiers in Ecology and Evolution, 2020
Hutchinson’s n-dimensional hypervolume concept holds a central role across different fields of ecology and evolution. The question of the amount of hypervolume overlap and differentiation between species is of great interest to understand the processes ...

Disentangling Exploitative and Interference Competition on Forest Dwelling Salamanders

Animals, 2023
Exploitative competition and interference competition differ in the way access to resources is modulated by a competitor. Exploitative competition implies resource depletion and usually produces spatial segregation, while interference competition is ...

Niche partitioning in a sympatric cryptic species complex [PDF]

Ecology and Evolution, 2016
AbstractCompetition theory states that multiple species should not be able to occupy the same niche indefinitely. Morphologically, similar species are expected to be ecologically alike and exhibit little niche differentiation, which makes it difficult to explain the co‐occurrence of cryptic species.

Trophic Niche Differentiation in Rodents and Marsupials Revealed by Stable Isotopes. [PDF]

PLoS ONE, 2016
Tropical rainforests support the greatest diversity of small mammals in the world, yet we have little understanding about the mechanisms that promote the coexistence of species.

Local and regional ecological morphology of dung beetle assemblages across four biogeographic regions [PDF]

, 2011
Aim Niche partitioning within species assemblages is thought to influence species packing and/or total niche space occupied. The evolution of dung beetles (Scarabaeinae) is likely to have been strongly influenced by inter-specific competition, leading to

Counting niches: Abundance‐by‐trait patterns reveal niche partitioning in a Neotropical forest [PDF]

Ecology, 2020
Abstract Tropical forests challenge us to understand biodiversity, as numerous seemingly similar species persist on only a handful of shared resources. Recent ecological theory posits that biodiversity is sustained by a combination of species differences reducing interspecific competition and species similarities increasing time to ...
