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 ...
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 ...
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. ...
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 ...

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 ...

Assessing the trophic niche of South American Terns integrating conventional and isotopic methods
(Csiro Publishing, 2016-12)
Conventional dietary studies combined with stable isotope analysis allowed the characterisation of the trophic niche of South American Terns (Sterna hirundinacea) breeding in Argentina. Direct observation of prey deliveries ...
Human-modified landscapes narrow the isotopic niche of neotropical birds
(Springer, 2021-04-09)
Deforestation and habitat loss resulting from land use changes are some of the utmost anthropogenic impacts that threaten tropical birds in human-modified landscapes (HMLs). The degree of these impacts on birds' diet, ...
Estimating the isotopic niche of males and females of false killer whales (Pseudorca crassidens) from Magellan Strait, Chile
(Wiley Blackwell Publishing, Inc, 2019-07)
Odontocete cetaceans, due to their size, abundance, and energetic requirements, consume large quantities of prey and may therefore have substantial influence on the structure and dynamics of ecosystems (Bowen 1997, Trites ...
