Effects of high density on spacing behaviour and reproduction in Akodon azarae: A fencing experiment
(Gauthier-villars/editions Elsevier, 2016-01)
We studied the short term spacing behavioural responses of Pampean grassland mouse (males exhibit a fusion spatial response.Akodon azarae) with regard to population density in four 0.25 ha enclosures (two control and two ...
Longitudinal distribution of Copepoda populations in the transition zone of Paranapanema River and Jurumirim Reservoir (São Paulo, Brazil) and interchange with two lateral lakes.
(2004-02-01)
Longitudinal changes in composition, abundance, and distribution of copepods were studied at the transition zone of Paranapanema River-Jurumirim Reservoir (SP, Brazil). The interchange of biotic material between marginal ...

Secondary kill effect of deltamethrin on triatoma infestans
(Oxford University Press, 2011)
Control of the Chagas disease vector, Triatoma infestans, relies on the application of pyrethroid insecticides, especially deltamethrin. We performed laboratory studies to determine whether a T. infestans nymph that comes ...
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 ...
Density dependence in the camelid Vicugna vicugna: the recovery of a protected population in Chile
(CAMBRIDGE UNIV PRESS, 2002)
The vicuna Vicugiia vicugna is a wild South American camelid. Following over-exploitation, which brought the species to the brink of extinction in Chile in the 1960s, the population was protected. Since 1975 the population ...
Feeding ecology, density and biomass of the freshwater turtle, Phrynops geoffroanus, inhabiting a polluted urban river in south-eastern Brazil
(2000-12-01)
This study examines the ecology of a population of Geoffroy's side-necked turtle Phrynops geoffroanus inhabiting a polluted urban river in Ribeirão Preto city, São Paulo state, south-eastern Brazil. Adult turtles fed mainly ...
