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. ...
Isotopic niches support the resource breadth hypothesis
(Blackwell Publishing Ltd, 2017)
© 2016 The Authors. Journal of Animal Ecology © 2016 British Ecological SocietyBecause a broad spectrum of resource use allows species to persist in a wide range of habitat types, and thus permits them to occupy large ...
Predicting occupancy and abundance by niche position, niche breadth and body size in stream organisms
(2018-01-01)
The regional occupancy and local abundance of species are thought to be strongly correlated to their body size, niche breadth and niche position. The strength of the relationships among these variables can also differ ...
Matching global and regional distribution models of the recluse spider Loxosceles rufescens: to what extent do these reflect niche conservatism?
(Blackwell Publishing Ltd, 2018)
© 2018 The Royal Entomological Society The Mediterranean recluse spider, Loxosceles rufescens (Dufour, 1820) (Araneae: Sicariidae) is a cosmopolitan spider that has been introduced in many parts of the world. Its bite can ...
Distribution, spatial interaction and niche analysis in three species of European moles (genus Talpa, Soricomorpha: Mammalia) in Italy
(Wiley Blackwell Publishing, Inc, 2017-12)
We investigated the spatial relationships among three phylogenetically related and ecologically convergent moles in Italy: Talpa europaea, Talpa romana and Talpa caeca. The spatial niche of each species was described through ...
Climatic niche dynamics of three widespread cardiospermum (paullinieae, sapindaceae) species revealed possible dispersal pathways
(American Society of Plant Taxonomists, 2020-12)
The genus Cardiospermum comprises eight species distributed in the American continent, from central-eastern United States of America to central Argentina, Uruguay, and Chile; C. corindum, C. grandiflorum, and C. halicacabum ...
Trophic niche expansion during the non‑breeding season in kelp gulls of known breeding colony
(Springer, 2018-12)
Year-round foraging strategies are key determinants of bird population dynamics. However, trophic ecology studies during the non-breeding period rarely focus on individuals from a known breeding colony, precluding links ...
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 ...
