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 ... -
Effect of vegetable oils as Phagostimulants in adults of Dichroplus vittigerum (Orthoptera: Acrididae)
