Geographical and intrapopulation variation in the diet of a threatened marine predator, Pontoporia blainvillei (Cetacea)
(Wiley-Blackwell, 2018-01-01)
Understanding diet variation is a major concern when developing conservation guidelines for threatened species, especially for marine predators whose prey availability can be reduced by commercial fisheries. Diet can vary ...
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 ...
Between-individual variation drives the seasonal dynamics in the trophic niche of a Neotropical marsupial

Diet Variation of a Generalist Predator, the American Kestrel Falco sparverius, in a Gradient of Agricultural Intensification in Central Argentina
(Polish Academy of Sciences. Museum and Institute of Zoology, 2021-03-20)
Agricultural expansion at the expense of natural habitats and the intensification processes in agricultural production are globally among the main causes of biodiversity and ecosystem services loss at large scale. This ...

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 ...
Generalist populations formed by generalist individuals: A case of study on the feeding habits of a neotropical stream fishPopulações generalistas formadas por indivíduos generalistas: Um caso de estudo sobre os hábitos alimentares de um peixe de riacho neotropical
(2021-01-01)
Aim: We described the diet of the generalist stream fish Knodus chapadae and we tested if the environmental conditions are associated with population’s diet and individual specialization. Methods: We analyzed the stomach ...
Seasonal variation in feeding habits and diet selection by wild boars in a semi-arid environment of Argentina
(Polish Academy of Sciences, 2013-01)
The wild boar, Sus scrofa, was first introduced for hunting purposes in Argentina in 1906 and presently occupies a wide range of habitats. Understanding the food habits of invasive species is important for predicting the ...
