Diversidade e abundância de aves costeiras em um trecho do litoral norte do Rio Grande do Sul, Brasil

Abstract: A avifauna litorânea é um importante elemento na dinâmica dos ecossistemas onde vive, sendo a planície costeira considerada uma área de altíssima prioridade para a conservação da biodiversidade regional. Devido à carência de informações sobre as aves que frequentam o litoral norte do Rio Grande do Sul, principalmente em trechos de intensa ocupação antrópica, e a importância desse grupo como um constituinte da biodiversidade, este artigo objetiva, com vistas à conservação, fornecer dados sobre a avifauna costei… Show more

“…This hypothesis is further supported by phylogenetically basal ANA (Amborellaceae, Nymphaeales and Austrobaileyaceae) grade angiosperms that completely lack acarodomatia, suggesting Early Cretaceous representatives of these linages also lacked acarodomatia. By contrast, some of the most basal woody lineages of magnoliid angiosperms including those in Piperales, Laurales and Magnoliales have acarodomatia [79]. While these clades evolved by about 125 Ma [76,78], they likely remained herbaceous until ca 100 Ma, consistent with our hypothesis that acarodomatia evolved about 100 Ma.…”

“…The rufous hornero (Furnarius rufus) is known for its insectivorous behavior, playing an important role in controlling agricultural pests and contributing to the maintenance of biodiversity in rural areas (Souza;Santos, 2007). Coastal birds, such as herons (Family Ardeidae), are predators of fish and other aquatic organisms that maintain the balance in fish populations in wetlands, contributing to the health of these aquatic ecosystems (Müller; De Barros, 2013). Furthermore, bird populations are often used as indicators of environmental health.…”

“…Essa família inclui espécies costeiras, que se reproduzem no Hemisfério Norte e têm na região costeira do Rio Grande do Sul um importante local de muda de plumagem e acúmulo de reservas de energia durante suas migrações (Vooren & Brusque, 1999). Vale mencionar que estudos prévios conduzidos no litoral norte do Rio Grande do Sul registraram a ocorrência de escolopacídeos no estuário do rio Tramandaí (Costa & Sander, 2008, Müller & Barros, 2013. A ausência dessas aves pode ser indício de que a crescente urbanização nos municípios de Imbé e Tramandaí esteja influenciando negativamente a estadia dessas aves no estuário (Accordi & Hartz, 2013).…”
