Effects of livestock grazing on flocks of seed-eating birds in the central monte desert, Argentina
(National Research Council Canada-NRC Research Press, 2019-03)
Animal populations often decline due to habitat disturbance, but the initial response of organisms to human-induced environmental change is usually behavioral. Intra-and inter-specific interactions can restrict or facilitate ...
Social interaction of juvenile Japanese quail classified by their permanence in proximity to a high or low density of conspecifics
(Poultry Science Association, 2013-10)
One challenge faced by ethologists in poultry welfare is helping birds to form functionally successful groups over time through the expression of appropriate behaviors. Searching for phenotypic variability, we developed ...
Greening at multiple scales promote biodiverse cities: A multi-scale assessment of drivers of Neotropical birds
(Elsevier GmbH, 2021)
© 2021 Elsevier GmbHBiodiversity-sensitive cities can contribute to reconnect humans with nature and halt global biodiversity loss. Achieving biodiversity-sensitive cities is challenging, especially in regions threatened ...
Evaluation of strain, dietary energy level and stocking density on broiler feathering
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2006-03-01)
This study evaluated the effects of strain, stocking density and dietary energy level on the feathering of broiler chickens. Four trials were carried out between September 2000 and April 2002. There were 10,685 broiler ...
Efeitos da densidade populacional e da energia da dieta sobre o desempenho de frangos de corte
(1997-03-01)
The experiment was conducted to determine the effect of feeding three levels of energy (2800, 3000 and 3200 kcal ME/kg) in diets and two stocking densities (10 and 22 birds/m 2) on broilers performance. The experimental ...

Efeito do Isolamento Térmico de Telhado Sobre o Desempenho de Frangos de Corte Alojados em Diferentes Densidades
(2000-09-01)
The work objective was to evaluate the effect of using a thermal insulating material installed as lining under the roof, on broiler performance, on environmental conditions of different broiler chickens stocking densities ...
Comunidade de aves aquáticas e suas interações em sistemas límnicos do sudeste brasileiro
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Ecologia e Recursos Naturais - PPGERN, 2008-02-27)
Aquatic birds do interact in many ways with freshwater ecosystems. Birds can be considered the most important dispersers of freshwater algae between water bodies. Moreover, birds also can contribute to nutrient loading in ...
Evaluation of Three Methods to Estimate Density and Detectability From Roadside Point Counts
(Universidad Nacional, Costa Rica., 2011)
Roadside point counts are often used to estimate trends of bird populations. The use of aural
counts of birds without adjustment for detection probability, however, can lead to incorrect population trend
estimates. We ...
Vegetation structure and livestock grazing intensity affect ground-foraging birds in xerophytic forests of Central-East Argentina
(Elsevier, 2022-10)
Ground birds are strongly associated with the vegetation structure in natural environments under livestock grazing. Birds that fed on the ground may be the most affected by overgrazing, while those that fed on the shrub ...
