Frontal and lateral visual system in birds: frontal and lateral gaze
(Karger, 1988)
Birds exhibit a variable retinal organization in terms of foveas and areas of high cell density. The distribution of these retinal structures in different species does not follow phylogenetic lines. In order to study this ...
Wetland Bird Response to Habitat Composition and Configuration at Multiple Spatial Scales
(Springer, 2020-09-23)
Wetlands loss has major consequences for biodiversity. The Delta of Paraná River is one of the largest wetland ecosystems in South America undergoing rapid conversion of freshwater marshes to pastures. We evaluated the ...
Hyper abundant mesopredators and bird extinction in an Atlantic forest island
(Sociedade Brasileira de Zoologia, 2009-06-01)
Islands can serve as model systems for understanding how biological invasions affect native species. Here we examine the negative effects of mesopredator mammals on bird richness at Anchieta Island, an 826 ha offshore ...

Bone mineral density of tibae and femura of broiler breeders: growth, development and production
(Fundação APINCO de Ciência e Tecnologia Avícolas, 2006-06-01)
The aim of this study was to follow-up the physiological variations in the development of the bone tissue, associating them with the egg production curve. This study was carried out in the facilities of the Faculdade de ...

Mist-nets versus point counts in the estimation of forest bird abundances in South-Central Chile
(2006)
We used variable-radius point counts and mist-netting to estimate forest bird abundances in the Maule Region of South Central Chile. Mist-netting detected a total of 25 species over 3 years and 3 seasons per year (Winter, ...
An assessment of the availability of cavities for secondary cavity-nesting birds in certified and conventionally-logged neotropical rainforests
(Italian Society of Silviculture and Forest Ecology, 2020-05)
The high level of forest intervention and the decrease in biodiversity as a result of logging are incentives to implement forest certification schemes. Despite the advances in the results of the impact of forest certification ...
Territory size, population density, and natural history of Cabanis’s Ground Sparrow, an endemic species found in urban areas
(2021)
Worldwide urban expansion threatens biodiversity inhabiting the original natural environments now being transformed, especially range-restricted species. Here, we provide estimates of population density, population size, ...
