At home in the tropics: seasonal niche-tracking by the Yellow-green Vireo, Vireo flavoviridis, an intratropical migrant

open access: yesRevista Mexicana de Biodiversidad, 2023
Migratory birds move geographically by tracking specific climatic conditions through time. However, we lack information about the climatic conditions birds are tracking, especially in intratropical migrants, whose movements are contained inside the ...

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

open access: yesAquatic 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.

Ecological Niche and Interspecific Association of Plant Communities in Alpine Desertification Grasslands: A Case Study of Qinghai Lake Basin

open access: yesPlants, 2022
The study of niche and interspecific relationships is one of the classical ecological theories. We set up four desertification gradients. The “Levins” and “Pianka” method were used to calculate the species’ niche breadth and niche overlap.

Asynchronous grammaticalization: V1-conditionals in present-day English and German [PDF]

open access: yes, 2015
The present paper contrasts verb-first (= V1-)conditionals in written usage in present-day English and German. Based on the hypothesis that V1-protases originated in independent interrogatives and then grammaticalized as conditional subordinate clauses ...

The evolution of niche overlap and competitive differences

open access: yesNature Ecology & Evolution, 2021
Competition can result in evolutionary changes to coexistence between competitors but there are no theoretical models that predict how the components of coexistence change during this eco-evolutionary process. Here we study the evolution of the coexistence components, niche overlap and competitive differences, in a two-species eco-evolutionary model ...

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

open access: yesPLoS 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 ...

Climatic niche comparison across a cryptic species complex [PDF]

open access: yesPeerJ, 2019
According to current molecular evidence, the Chionaspis pinifoliae heterophyllae species complex has been recognized as 10 cryptic species. In this study, we construct potential distribution maps for seven cryptic species based on climatic variables ...

Nest niche overlap among the endangered Vinaceous-breasted Parrot (Amazona vinacea) and sympatric cavity-using birds, mammals, and social insects in the subtropical Atlantic Forest, Argentina [PDF]

open access: yes, 2017
Many forest bird species require tree cavities for nesting, and share this resource with a diverse community of animals. When cavities are limited, niche overlap can result in interspecific competition, with negative consequences for threatened ...

Niche tracking and rapid establishment of distributional equilibrium in the house sparrow show potential responsiveness of species to climate change. [PDF]

open access: yes, 2012
The ability of species to respond to novel future climates is determined in part by their physiological capacity to tolerate climate change and the degree to which they have reached and continue to maintain distributional equilibrium with the environment.

Chironomidae larvae (Diptera) of Neotropical floodplain: overlap niche in different habitats

open access: yesBrazilian Journal of Biology
The niche overlap between trophic groups of Chironomidae larvae in different habitats was observed between trophic groups and between different environments in Neotropical floodplain.
