Diversidade de aves costeiras associada aos impactos ambientais em ecossistemas litorâneos

Abstract

Coastal birdlife comprises the assemblages of birds that normally border the coast, occupying part of the Litoral Surface and Tableland environments, in addition to a short oceanic strip, where they usually forage and even nest. In addition to resident bird species, visits by migratory bird species, mainly from the boreal hemisphere, towards Patagonia occur particularly at the end and beginning of the year in the Southern Hemisphere. It is worth mentioning that birds are excellent environmental bioindicators, as they are relatively faithful in their diet and preferred habitat, and consequently in their functional diversity. Therefore, any change in your guild and environment can alter its population dynamics over time. Thus, based on understanding the behavior and understanding of the diversity (richness, composition and abundance) of birds in the face of adverse impacts on the coast, this study aims to investigate how these assemblages of birds are responding, focusing mainly on their trophic guild and their habitat. The increase in demand for housing, expanding the urban centers of coastal cities and the growing demand for energy sources (wind turbines), has been suppressing the territorial space of fauna, especially in birds, whose populations may decline due to the lack of characterization of their foraging areas. In this context, we propose to better study the functional diversity of birds, aiming to understand this synecological dynamics, and the anthropic impacts, in the region.
