Climatic-niche breadth, niche position, and speciation in lizards and snakes

open access: yesJournal of Biogeography
Aim: The climatic niche is associated with diversification in many groups of animals and plants. However, the relationships between climatic-niche breadth evolution, climatic-niche position evolution, and speciation remain underexplored.

Niche theory for positive plant–soil feedbacks

Ecology, 2023
AbstractInteractions between plants and the soil are an important ecological process in terrestrial ecosystems as they affect plant community structure: when and where we find different plant species. Those interactions are typically thought of as one‐directional: local soil conditions filter through dispersing species to produce a community of locally

Estimates of niche position and breadth vary across spatial scales for native and alien inland fishes

open access: yesGlobal Ecology and Biogeography, 2023
We estimate and compare niche position, marginality and breadth of Iberian inland fishes at three geographical extents (regional, restricted to the species’ range and global) to understand the effect of spatial scale on niche metrics.

Expanding the ecological niche approach: Relationships between variability in niche position and species richness

Ecological Complexity, 2011
The concept of ecological niche has remained as one of the core ideas in ecological research for almost a century. Various metrics describing niche overlap, breadth, and position have been developed during the last decades, and these have played a central role in our understanding of community organisation. However, owing to some obvious limitations in

Untangling the importance of niche breadth and niche position as drivers of tree species abundance and occupancy across biogeographic regions

open access: yesGlobal Ecology and Biogeography, 2020
AbstractAimEcological niches shape species commonness and rarity, yet, the relative importance of different niche mechanisms within and across ecosystems remains unresolved. We tested the influence of niche breadth (range of environmental conditions where species occur) and niche position (marginality of a species’ environmental distribution relative ...
