Inventario y áreas complementarias para la conservación de las aves de la provincia de Entre Ríos, Argentina

Abstract

The Neotropical region is characterized by the high species richness of birds, whose protection and inventories show biases due to lack of geographic representation and species diversity. In Entre Ríos province its protected areas have not been well established, generating biases in biodiversity representativeness. We updated the birds' inventory of Entre Ríos with 80,000 records. The province was divided into 39 cells of 0.5° lat-long to analyze birds' richness and priority areas through a complementary analysis. The Protected Areas (PAs) system was overlapped with the complementary areas to detect gap conservation areas. Entre Ríos presents 396 bird species and needs 10 cells to protect them all. The priority areas included cells on the Paraná and Uruguay rivers. These priority areas overlap poorly with the current PAs system. We recommend the creation of new PAs or change the protection categories of PAs that overlap with priority areas selected. This work revaluates the importance of updated inventories to perform spatial prioritization and contrast the current PAs system to generate representative and efficient systems.

Primer registro documentado de Yal Negro (Rhopospina fruticeti)

“…Asimismo, el 27 de julio de 2006 se observó un macho juvenil y una hembra en la Estancia La Salamandra, departamento Vera (28°44'S, 60°44'O) en los bajos submeridionales, Santa Fe (Fandiño & Pautasso 2009). Hasta el momento la especie no había sido reportada para la provincia de Entre Ríos (Sarquis et al 2021), aunque existe un registro inédito de un individuo macho junto a un grupo de Zonotrichia capensis en un ambiente de arbustos en el acceso al salto de Méndez, departamento Gualeguaychú, el 22 de julio de 1996 (Bodrati in litt. 2022).…”
