Diet switching of seed-eating birds wintering in grazed habitats of the central Monte Desert, ArgentinaModificación de la dieta invernal de las aves granívoras en hábitats sujetos a pastoreo de la porción central del Desierto del Monte, Argentina
(Cooper Ornithological Society, 2017-08)
Although bird population declines associated with land degradation are common, the initial response of organisms to rapid human-induced environmental change is usually behavioral. Reductions in seed availability due to ...
Predicting how seed-eating passerines respond to cattle grazing in a semi-arid grassland using seed preferences and diet
(Elsevier Science, 2020-02)
Numerical responses of animals to habitat perturbation often seem inconsistent, spreading skepticism about the predictive capacity of applied ecology. Domestic grazing changes several habitat variables that can affect ...

Nutrients in fruits as determinants of resource tracking by birds
(Wiley Blackwell Publishing, Inc, 2015-07)
Fruit pulp is an important source of nutrients for many bird species. Fruit-eating birds use a variety of strategies to cope with changes in the availability of fruits, exhibiting a remarkable ability to track resources. ...
Invasive american mink mustela vison in wetlands of the cape horn biosphere reserve, southern Chile: What are they eating?
(Cambridge University Press, 2009-01)
The impact of alien American mink on the native fauna of oceanic islands has been demonstrated in a number of locations. In the sub-Antarctic Cape Horn Biosphere Reserve of southern Chile the species is currently expanding ...
Context-dependent foraging by seed-eating birds does not necessarily mean low ecological predictability
(National Research Council Canada-NRC Research Press, 2015-03)
Flexibility of foraging behaviour affects our capacity to predict ecological outputs such as population responses to habitat change. Some birds forage following rules of absolute value of the food item (i.e., absolute ...
