DOIAbstract
The different ways in which biodiversity is distributed on Earth have always intrigued ecologists, promoting constant research to elucidate the causes and mechanisms that guide their spatial patterns. Numerous hypotheses have been proposed to explain biodiversity across the world. In South American Subtropical Dry forests, a global deforestation hotspot, this type of research remains poorly explored. We aimed to evaluate the response of forests bird communities to different biophysical and environmental factors analyzed simultaneously under three major hypotheses in ecology. Generalized linear mixed models (GLMMs) were used to analyze the seasonal richness and relative frequency in birds for 27 forest sites scattered through the Dry Chaco, ...
