Bird functional and taxonomic diversity in xerophytic forests: contributing to balance bird conservation and livestock production
Barzan, Flavia Romina; Bellis, Laura Marisa; Canavelli, Sonia Beatriz; Calamari, Noelia Cecilia; Dardanelli, Sebastian (Elsevier, 2023-10)Biodiversity is increasingly dependent on the ecological state of agricultural and livestock systems. Here, we assess the relationship between bird functional and taxonomic diversity and forest structure along a gradient ... -
¿Eligen las palomas y cotorras los lotes de soja (Glycine max) enemergencia? Un caso de estudio en agroecosistemas de Entre Ríos, Argentina = Do pigeons and parakeets choose soybean (Glycine max) crops during the emergence? A case studyon agroecosystems in Entre Ríos, Argentina
Dardanelli, Sebastian; Fandiño, Blas; Calamari, Noelia Cecilia; Canavelli, Sonia Beatriz; Zaccagnini, Maria Elena (Instituto de Biología, Universidad Nacional Autónoma de México, 2016-12)Las palomas y cotorras pueden resultar perjudiciales para cultivos anuales en algunas regiones de Sudamérica. En este estudio analizamospatrones de uso de hábitat de las palomas torcaza (Zenaida auriculata), manchada ... -
Long-term association of Tyrannus savana and Sturnella superciliaris density with land cover and climatic variables in agroecosystems of Argentina
Calamari, Noelia Cecilia; Cerezo, Alexis; Canavelli, Sonia Beatriz; Dardanelli, Sebastian; Gavier Pizarro, Gregorio Ignacio; Zaccagnini, Maria Elena (Aves Argentinas/Asociación Ornitológica del Plata, 2016-12)Agricultural expansion and intensification resulted in important changes in the agricultural landscape of the Pampas region, Argentina. We used linear mixed models to analyze the relationship between environmental variables ... -
Patch and landscape responses of bird abundance to fragmentation in agroecosystems of east-central Argentina = Abondance d'oiseaux dans les îlots et les paysages à la suite de la fragmentation dans des agrosystèmes du centre-est de l'Argentine
Calamari, Noelia Cecilia; Vilella, Franciso J.; Sica, Yanina Vanesa; Mercuri, Pablo Alberto (Society of Canadian Ornithologists and Bird Studies Canada, 2018)Forest fragmentation in agroecosystems is linked to declines of avian species worldwide. Agriculture has greatly reduced native forest cover in east-central Argentina. Assessing the influence of fragmentation on forest ... -
Variations in pest bird density in Argentinean agroecosystems in relation to land use and/or cover, vegetation productivity and climate
Calamari, Noelia Cecilia; Canavelli, Sonia Beatriz; Cerezo, Alexis; Dardanelli, Sebastian; Bernardos, Jaime Nicolás; Zaccagnini, Maria Elena (CSIRO, 2018-12-05)Context: Changes in environmental conditions may influence bird populations, including pest bird species, and their distribution. In Argentina, particularly in the Pampas region, agricultural expansion has resulted in ... -
Vegetation structure and livestock grazing intensity affect ground-foraging birds in xerophytic forests of Central-East Argentina
Dardanelli, Sebastian; Calamari, Noelia Cecilia; Canavelli, Sonia Beatriz; Barzan, Flavia Romina; Goijman, Andrea Paula; Lezana, Lucrecia (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 ...
