Future paths for the ‘exploitative segregation of plant roots’ model
(2021-01-01)
The exploitative segregation of plant roots (ESPR) is a theory that uses a game-theoretical model to predict plant root foraging behavior in space. The original model returns the optimal root distribution assuming exploitative ...
Effect of population density on diet composition and dietary niche breadth of guanaco (Lama guanicoe, Müller 1776) in northeastern Patagonian steppes
(Elsevier, 2019-11)
The optimal foraging theory postulates that as animal population density increases, the progressive decline in preferred forage availability results in changes in diet composition and widening of dietary niche breadth. For ...

Understanding and manipulating diet choice in grazing animals
(Csiro Publishing, 2015-01)
Conventional models of foraging, such as optimal foraging theory, generally take the univariate approach to explain the decisions of consumers on the basis of the intrinsic properties of foods, including nutrient concentration ...
Comportamento e uso de habitat por aves dependentes de áreas úmidas no interior do estado de São Paulo
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ecologia e Recursos Naturais - PPGERN, 2014-10-08)
The human pressures in aquatics ecosystems are very strong and affect all associated fauna. The waterbirds are a major environmental group in these ecosystems. To April / 2013 until April /2014 were collected the foraging ...
Changes in intrapopulation resource use patterns of an endangered raptor in response to a disease-mediated crash in prey abundance
(WILEY-BLACKWELLHOBOKEN, 2012)
1. A long-standing question in ecology is how natural populations respond to a changing environment. Emergent optimal foraging theory-based models for individual variation go beyond the population level and predict how its ...
Interindividual variations in plant and fruit traits affect the structure of a plant-frugivore network
(Elsevier B.V., 2019-02-01)
Frugivores select their food in a hierarchical way, from plants to individual fruits, to meet their nutritional requirements. According to the optimal diet theory, finding, handling, and digesting fruits is costly, thus ...
Food selection and predation risk in the Andean white-eared opossum (Didelphis pernigra Allen, 1900) in a suburban area of Bogotá, Colombia
(2017)
Urbanization is spreading throughout the Andes, and despite it there is still wildlife which survives in these novel environments throughout Colombia and elsewhere. The Andean white-eared opossum (Didelphis pernigra Allen, ...
