The relationship between niche breadth and geographic range size in African Horseshoe bats (Rhinolophidae, Chiroptera) [PDF]

open access: yes, 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.

Trophic position structures physiological trade-offs between metabolic and detoxification pathways in sympatric passerinesTrophic position structures physiological trade-offs between metabolic and detoxification pathways in sympatric passerines [PDF]

open access: yesRoyal Society Open Science
Resource use links ecological context to organismal performance, yet whether dietary breadth or trophic position is more closely associated with physiological state in wild birds remains unclear.

Is the relationship between body size and trophic niche position time-invariant in a predatory fish? First stable isotope evidence. [PDF]

open access: yesPLoS ONE, 2010
Characterizing relationships between individual body size and trophic niche position is essential for understanding how population and food-web dynamics are mediated by size-dependent trophic interactions.

gerardommc/Niche-centroids: Final

open access: yes, 2022
Final version of the analyses of the paper: Gerardo Martín, Carlos Yáñez-Arenas & Xavier Chiappa-Carrara (2022). Discrepancies between point process models and environmental envelopes identify the niche centroid – geography configuration.

Invasion success of a global avian invader is explained by within-taxon niche structure and association with humans in the native range [PDF]

open access: yes, 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 ...

The Role of Pleiotropy in the Evolutionary Maintenance of Positive Niche Construction

open access: yesThe American Naturalist, 2018
Organisms often modify their environments to their advantage through a process of niche construction. Environments that are improved through positive niche construction can be viewed as a public good. If free riders appear that do not contribute to the shared resource and therefore do not incur any associated costs, the constructed niche may become ...

Historical niche partitioning and long‐term trophic shifts in Laurentian Great Lakes deepwater coregonines

open access: yesEcosphere, 2018
Over the last 100 yr, anthropogenic stressors have decimated the assemblage of deepwater coregonines that once underpinned the food webs of the Laurentian Great Lakes.

Impact of the Belt and Road Initiative on Economic-Social-Natural Ecological Niches and Their Coupling Coordination: Evidence From 11 Countries Along the Route

open access: yesFrontiers in Environmental Science, 2022
The Belt and Road Initiative (BRI) significantly contributes to the world economy. However, the central part of the Belt and Road (B&R) is located in fragile ecological zones that are arid, semi-arid, or sub-humid.
