Effects of fire disturbance on bird communities and species of mountain Serrano forest in central Argentina
Albanesi, Sebastián; Dardanelli, Sebastian; Bellis, Laura Marisa (Taylor & Francis, 2014)In central Argentina, Serrano forest has a long history of fire disturbance; however, the impact of fire on avifauna remains unknown. We compared the avian–habitat relationships in forest patches with low, moderate, and ... -

Influences of succession and erosion on bird communities in a South American highland wooded landscape
Bellis, Laura Marisa; Pidgeon, Anna Michle; Alcántara, Camilo; Dardanelli, Sebastian; Radeloff, Volker C. (Elsevier, 2015-08-01)In South American highland forests, domestic grazing can cause major changes in forest structure and soil quality thereby altering resources available to avian communities. However, the consequences of changes in variability ... -
Inventario y áreas complementarias para la conservación de las aves de la provincia de Entre Ríos, Argentina
Sarquis, Juan Andrés; Giraudo, Alejandro Raúl; Reales, César Fabricio; Dardanelli, Sebastian (Universidad Nacional Autónoma de México (UNAM), 2021)La región neotropical se caracteriza por su gran riqueza de aves, cuya protección e inventarios presentan sesgos de representación geográfica y composición de especies. En la provincia de Entre Ríos, las áreas protegidas ... -
Livestock grazing constraints bird abundance and species richness: a global meta-analysis
Barzan, Flavia Romina; Bellis, Laura Marisa; Dardanelli, Sebastian (Elsevier, 2021-08)Balancing food production and biodiversity conservation is a global challenge today. Livestock grazing is one of the main activities triggering habitat degradation and land-use change around the world. Its effects on ... -
