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. ...
Feeding and reproductive patterns of Astyanax intermedius in a headwater stream of Atlantic Rainforest
(Acad Brasileira De Ciencias, 2015-12-01)
In this paper, we determined diet composition, reproductive periodicity and fecundity of Astyanax intermedius in a headwater stream of a State Park of an Atlantic rainforest. We also evaluated the influence of rainfall, ...
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 ...
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 ...
Dietary and isotopic specialization: The isotopic niche of three cinclodes ovenbirds
(2009)
By comparing the isotopic composition of tissues deposited at different times, we can identify individuals that shift diets over time and individuals with constant diets. We define an individual as an isotopic specialist ...
The effects of spatial scale and isoscape on consumer isotopic niche width
(2018)
1. The mean and variance of ecological variables are dependent on sampling attributes such as the coverage of environmental heterogeneity (sampling extent) and spatial scale. Trophic niche width is often approximated by ...
Temperature and pH define the realised niche space of arbuscular mycorrhizal fungi
(Wiley-Blackwell, 2021-03-04)
The arbuscular mycorrhizal (AM) fungi are a globally distributed group of soil organisms that play critical roles in ecosystem function. However, the ecological niches of individual AM fungal taxa are poorly understood. ...
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, ...
