Niche partitioning and the role of intraspecific niche variation in structuring a guild of generalist anurans [PDF]
Royal Society Open Science, 2017 Intra-population niche differences in generalist foragers have captured the interest of ecologists, because such individuality can have important ecological and evolutionary implications. Few researchers have investigated how these differences affect the relationships among ecologically similar, sympatric species.

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 ...

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.

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 ...

Ecosphere, 2023 Ecological theory posits that higher species richness should be associated with greater exploitation of resources and niche packing resulting from either increasing species niche overlap or specialization of species' niches.

Belowground niche partitioning is maintained under extreme drought
Ecology, 2023 AbstractBelowground niche partitioning presents a key mechanism for maintaining species coexistence and diversity. Its importance is currently reinforced by climate change that alters soil hydrological conditions. However, experimental tests examining the magnitude of its change under climate change are scarce. We combined measurements of oxygen stable

Isotopic niche partitioning and individual specialization in an Arctic raptor guild [PDF]
Oecologia, 2021 Abstract Intra- and inter-specific resource partitioning within predator communities is a fundamental component of trophic ecology, and one proposed mechanism for how populations partition resources is through individual niche variation. The Niche Variation Hypothesis (NVH) predicts that interindividual trait variation leads to functional trade-

Three-dimensional niche partitioning between two colonially nesting ardeid species in central China
Avian Research, 2021 Background Interspecific competition is known to be strongest between those species that are both closely related and sympatric. Egrets are colonially nesting wetland birds that often overlap and can therefore be expected to compete in roosting and ...

Dynamic trait-niche relationships shape niche partitioning across habitat transformation gradients
Basic and Applied Ecology, 2022 Multidimensional approaches examining complex trait-niche relationships are crucial to understand community assembly. This is particularly important across habitat transformation gradients because specialists are progressively substituted by generalists ...

Niche partitioning by sympatric civets in the Himalayan foothills of Pakistan
PeerJ, 2023 Niche overlap between sympatric species can indicate the extent of interspecific competition. Sympatric competing species can exhibit spatial, temporal, and dietary adjustments to reduce competition. We investigated spatial, temporal, and dietary niche overlap of sympatric Asian palm civet (Paradoxurus hermaphroditus) and small Indian civet ...
