Avifauna da Estação Ecológica dos Caetetus, interior de São Paulo, Brasil

Abstract

A Estação Ecológica dos Caetetus possui um dos maiores remanescentes de mata estacional semidecídua ainda presentes no Estado de São Paulo. Poucos estudos foram realizados nessa localidade, extremamente importante no que diz respeito às aves da Mata Atlântica do interior do Estado. Para caracterizar a avifauna da estação com dados recentes e contribuir com novos registros, foi realizado um levantamento da avifauna utilizando-se o método de Pontos de Escuta entre outubro de 2005 e dezembro de 2006. Foram registradas 226 espécies enquanto diversos autores registraram outras 68, para um total de 293. Muitas espécies são endêmicas da Mata Atlântica ou do Cerrado e algumas são ameaçadas no Estado, justificando a existência dessa unidade de conservação e provando a necessidade de inventários em longo prazo e da preservação de fragmentos de mata estacional semidecídua nativa.

Bird sensitivity to disturbance as an indicator of forest patch conditions: An issue in environmental assessments

“…Because we studied smaller (five landscapes of 16 km 2 ) and highly deforested (11% forest cover) landscapes, and we observed only one high-sensitivity species according to Parker, we believe that higher richness of Parker's high-sensitivity species are primarily found in less deforested and impacted landscapes. Other studies performed in larger and protected Atlantic Forest patches also found elevated richness of high-sensitivity species, corroborating our assumption (e.g., more than 15 forest high-sensitivity species were reported in Develey and Martensen, 2006;Cavarzere et al, 2009;Antunes et al, 2013). This condition may explain the lack of relationship between Parker's high-sensitivity species and the variation of forest environmental conditions in more disturbed landscapes.…”

“…Even though we found the same result, we observed that the species we documented in this category encompass forest species very common in disturbed sites (e.g., Patagioenas picazuro, Tangara cayana, Brotogeris chiriri, Tolmomyias sulphurescens, Icterus pyrrhopterus), even urban zones (e.g., Franz et al, 2010;Cruz and Piratelli, 2011;Alexandrino et al, 2013), but also include some species naturally considered more vulnerable to habitat loss and fragmentation, such as endemic (e.g., Automolus leucophthalmus, Conopophaga lineata, Drymophila ferruginea, Mackenziaena severa) and near-threatened and threatened species (e.g., the near threatened species Amazona aestiva, Antilophia galeata, Campephilus robustus, Leptodon cayanensis and Penelope superciliaris, the vulnerable species Cyanoloxia brissonii, and the endangered species Lanio penicillatus). These last are mainly reported in large and preserved patches (e.g., Anjos, 2006;Develey and Martensen, 2006;Cavarzere et al, 2009;Antunes et al, 2013). Thus, we noticed that the existing relationship between the richness of Parker's medium-sensitivity level and our measurement of forest environmental conditions (i.e., the rank of ecosystem service provisioning from Ferraz et al, 2014) has occurred in our study area only by the presence of these listed species.…”

Birds of Estação Ecológica da Serra das Araras, state of Mato Grosso, Brazil: additions and review

“…In evaluating the richness of birds reported to EESA, it is observed a higher number of species recorded in relation to several areas of the Cerrado (see Valadão 2012), as well as several other protected areas in Brazil (Motta-Junior et al 2008, Cavarzere et al 2009, Aleixo and Guilherme 2010, with methodological reservations. Its expressive number of species places EESA among the richest protected areas in terms of bird species in Brazil (Pacheco et al 2007, Pinheiro and Dornas 2009, Somenzari et al 2011, especially in terms of areas not primarily covered by forest.…”

Low trophic niche overlap among trap-nesting bee species (Hymenoptera: Anthophila) in a semideciduous forest fragment

“…In spite of being immersed in an altered matrix of agricultural lands with a high density of invasive grasses throughout its surroundings (Melo et al 2007), the large forest fragment in CES hosts a highly complex and species-rich flora (Durigan et al 2000;Melo et al 2007;Udulutsch et al 2010), which provides a broad range of floral resources to the bees and also different nesting substrates such as dead wood and hollow twigs (Krombein 1967) for the cavity-nesting species. In addition, the fact that the region is located in a transitional area between two biodiversity hotspots, i.e., Atlantic Rainforest and Cerrado ecosystems (Myers et al 2000), may explain the high species richness of some groups such as anurans (Brassaloti et al 2010), birds (Cavarzere et al 2009), bats (Pedro et al 2001), and also cavitynesting wasps and bees (Rocha-Filho et al 2017).…”
