Grassland degradation induces high dietary niche overlap between two common livestock: cattle and sheep

Journal of Sustainable Agriculture and Environment, 2023
Introduction Diet selection of grazing livestock is one of the critical factors affecting the diversity and composition of plant communities in grasslands, with consequent impacts for ecosystem functioning.

Niche Overlap and Diffuse Competition [PDF]

Proceedings of the National Academy of Sciences, 1974
Current theory predicts a distinct upper limit on the permissible degree of niche overlap; moreover, theory suggests that maximal tolerable overlap should be relatively insensitive to environmental variability. Data presented here demonstrate that, within the lizard subset of natural desert communities, niche overlap decreases both with increasing ...

Peri‐urban systems alter trophic niche size and overlap in sympatric coastal bird species

Ecosphere, 2023
Urban habitats can create empty trophic niche space by providing abundant alternative dietary resources, allowing some generalist species to either shift or expand their trophic niches.

Spatio-Temporal Niches of Main Fish Species in the Mangrove Creeks of the Nanliujiang River Estuary

Redai dili, 2023
Mangroves are one of the most important wetland ecosystems. The development of fisheries in tropical and subtropical bays or estuaries is closely associated with mangroves since the high heterogeneity of the mangrove ecosystem provides a suitable habitat

Trophic position and niche overlap of an Asian weatherfish (Misgurnus bipartitus), western tubenose goby (Proterorhinus semilunaris) and native benthic fish species [PDF]

Aquatic Invasions
Co-occurring and morphologically similar species have adapted to differential niches to minimize competition. An invasive alien species can occupy an ‘empty niche’ in introduced ranges.

Cohabitation Study of Tricolour Langur (Presbytis chrysomelas ssp. cruciger) and Proboscis Monkey (Nasalis larvatus) in Bukit Semujan Danau Sentarum National Park

Jurnal Ilmu Kehutanan, 2023
The  tricolour langur and proboscis monkey in Bukit Semujan cohabited and utilized the same resources. Cohabitation, mainly due to resource constraints, needed substantial attention to ensure the survival of these primates. This research aimed to map the

The role of ecological niche evolution on diversification patterns of birds distinctly distributed between the Amazonia and Atlantic rainforests.

PLoS ONE, 2020
The Amazonian and Atlantic Forest share several organisms that are currently isolated but were continuously distributed during the Quaternary period. As both biomes are under different climatic regimes, paleoclimatic events may have modulated species ...
