The dimensionality of individual niche variation
(2018-03-01)
The inherently multidimensional nature of the niche has not yet been integrated into the investigation of individual niche specialization within populations. We propose a framework for modeling the between- and within-individual ...
Testing the niche variation hypothesis in a community of passerine birds
(Ecological Society of America, 2017)
The niche variation hypothesis (NVH) predicts that populations with broader niches should exhibit greater between- individual diet variation or individual specialization (IS) relative to populations with narrower niches. ...
Individual diet specialisation in sparrows is driven by phenotypic plasticity in traits related to trade-offs in animal performance
(Wiley Blackwell Publishing, Inc, 2019-01)
Individual diet specialisation (IS) is frequent in many animal taxa and affects population and community dynamics. The niche variation hypothesis (NVH) predicts that broader population niches should exhibit greater IS than ...
Individual diet specialisation in sparrows is driven by phenotypic plasticity in traits related to trade-offs in animal performance
(Blackwell Publishing Ltd, 2019)
© 2018 John Wiley & Sons Ltd/CNRS Individual diet specialisation (IS) is frequent in many animal taxa and affects population and community dynamics. The niche variation hypothesis (NVH) predicts that broader population ...
Latitudinal gradients in intraspecific ecological diversity
(Royal Soc, 2013-12-23)
The increase in the number of species with decreasing latitude is a striking pattern of global biodiversity. An important feature of studies of this pattern up to now has been the focus on species as the fundamental unit ...
Climatic niche breadths of the Atlantic Forest snakes do not increase with increasing latitude
(Oxford Univ Press, 2021-11-06)
The climatic niche is a central concept for understanding species distribution, with current and past climate interpreted as strong drivers of present and historical-geographical ranges. Our aim is to understand whether ...
Individual-level diet variation in four species of Brazilian frogs
(WILEY-BLACKWELL PUBLISHING, INC, 2009)
Many natural populations exploiting a wide range of resources are actually composed of relatively specialized individuals. This interindividual variation is thought to be a consequence of the invasion of `empty` niches in ...
Competition and resource breadth shape niche variation and overlap in multiple trophic dimensions
(2019-05-15)
Competition plays a central role in the maintenance of biodiversity. A backbone of classic niche theory is that local coexistence of competitors is favoured by the contraction or divergence of species' niches. However, ...
Seasonal population and individual niche dynamics in a tetra fish in the Pantanal wetlands
(2017-07-01)
In seasonal tropical regions, rainfall and/or temporary floods during the wet season generally increase the abundance and diversity of food resources to many consumers as compared to the dry season. Therefore, seasonality ...
The influence of niche and neutral processes on a neotropical anuran metacommunity
(Wiley-Blackwell, 2014-08-01)
One of the most important questions in ecology is the relative importance of local conditions (niche processes) and dispersal ability (neutral processes) in driving metacommunity structure. Although many studies have been ...
