The Flooding Pampas is the most important livestock region of Argentina, but is a region where replacement of originally natural, perennial tussock grasses by pasture species is changing the heterogeneity of the grassland ...

Fire is an ecological factor which seasonally affects fire-prone ecosystems, such as grasslands and open savannas of the Cerrado, and changes some patterns of the biota. This study aimed to investigate the influence of ...

We present an assessment of the Southern Paraguayan Grasslands using Important Bird Areas (IBAs) located in a grassland landscape mosaic. Eleven IBAs in southern Paraguay were evaluated 10 years after their designation, ...

Natural grasslands are declining due to loss, fragmentation and degradation, resulting in the decline of grassland-associated bird species. The Pampas Biome in south Brazil is not exception to this worldwide trend, facing ...

We evaluated how grazing affects bird assemblages in short and tall coastal salty grasslands at Samborombón Bay, Argentina. We studied ranches with three patterns of grazing (spatial rotation, continuous, and winter grazing) ...

Knowledge of the breeding biology of grassland birds is important given the accelerated rate of transformation of their habitats, which has led to noticeable population declines of many species. Although several species ...

The Neotropical Region has experienced large habitat transformations as a result of intensified agriculture. These changes have affected the populations of many species of birds in the Espinal ecoregion of Argentina. ...

Few studies have found strong evidence to suggest that ecotones promote species richness and diversity. In this study we examine the responses of a high-Andean bird community to changes in vegetation and topographical ...
