A tale of two seasons: The link between seasonal migration and climatic niches in passerine birds
Ecology and Evolution, 2020 The question of whether migratory birds track a specific climatic niche by seasonal movements has important implications for understanding the evolution of migration, the factors affecting species' distributions, and the responses of migrants to climate ...

Invasion success of a global avian invader is explained by within-taxon niche structure and association with humans in the native range [PDF]
, 2015 Aim To mitigate the threat invasive species pose to ecosystem functioning, reli- able risk assessment is paramount. Spatially explicit predictions of invasion risk obtained through bioclimatic envelope models calibrated with native species distribution ...

Ecology and Evolution, 2020 Pikas (Ochotona Link, 1795) are high‐altitude specialist species making them a useful bioindicator species to warming in high‐altitude ecosystem. The Himalayan Mountains are an important part of their range, supporting approximately 23%–25% of total pika

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 ...

The relationship between niche breadth and geographic range size in African Horseshoe bats (Rhinolophidae, Chiroptera) [PDF]
, 2011 According to Brown's hypothesis, generalists have high niche breadth and can tolerate a wide variety of environmental conditions resulting in large geographic range sizes. Conversely, specialists have low niche breadth and small range sizes.

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

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.
