“…Owl richness of the study region was similar to that found at other Atlantic Forest localities (Amaral 2007, Fink et al 2012. It was also similar to the six species reported by Borges et al (2004) and the eight species reported by Lloyd (2003), both from the Amazonian Forest and using the same methods as the present study.…”

Owl Assemblages in Fragments of Atlantic Forest in Brazil

· Habitat loss and fragmentation is recognized as one of the main causes of global biodiversity declines. Birds of prey are considered good environmental bioindicators because they are sensitive to changes in the environment and can suffer local extinctions due to habitat fragmentation. In this study, we aimed to determine whether forest fragment area is correlated with the richness and abundance of owl species, and whether owl species recorded exhibit preferences for fragment edge or interior. The study was undertaken in six remnants of southeastern Atlantic Forest located in Minas Gerais State, Brazil. Six species of owls were recorded: Buff-fronted Owl (Aegolius harrisii), Tropical Screech-Owl (Megascops choliba), Tawny-browed Owl (Pulsatrix koeniswaldiana), Striped Owl (Asio clamator), Mottled Owl (Strix virgata), and Rusty-barred Owl (Strix hylophila). Megascops choliba was the most abundant species. The richness and abundance of species were higher at the edge when compared to the interior of the fragments. The owl species recorded did not seem to prefer the forest interior, while M. choliba had a preference for forest edges. This study adds new empirical knowledge on the effects of fragmentation on Neotropical owl communities.Resumen · Comunidades de lechuzas y búhos en fragmentos de bosque Atlántico en Brasil El proceso de pérdida y fragmentación del hábitat se identifica como una de las principales causas del declive de la biodiversidad mundial. Las aves de presa se consideran un buen bioindicador ambiental porque son sensibles a los cambios en el medio ambiente y pueden extinguirse localmente con la fragmentación del bosque. El objetivo del estudio fue responder a las siguientes preguntas: ¿La fragmentación de los bosques influyen en la riqueza y abundancia de las especies de búhos? ¿Las especies de búho tienen preferencia por el borde o el interior de los fragmentos del bosque? El estudio se llevó a cabo de octubre de 2011 a septiembre de 2012 en seis localidades de la Mata Atlántica suroriental, ubicadas en el estado de Minas Gerais, Brasil. Seis especies de búhos fueron registradas: Lechucita Acanelada (Aegolius harrisii), Currucutú Común (Megascops choliba), Lechuzón Mocho Chico (Pulsatrix koeniswaldiana), Búho Gritón (Asio clamator), Mocho Carijó (Strix virgata) y Rusty-barred Owl (Strix hylophila). M. choliba fue la especie más abundante. La riqueza y abundancia de especies fue mayor en el borde comparado con el interior de los fragmentos. La comunidad de búhos en nuestra área de estudio no parece tener preferencia por el interior del bosque, sin embargo, M. choliba es más abundante en los bordes del bosque. Este estudio aporta nuevos conocimientos sobre la riqueza y abundancia de los búhos Neotropicales y su respuesta a la fragmentación de la Mata Atlántica.

“…Within Brazil, this model could be applied to the role of private reserves in conservation of other threatened species in the Atlantic Forest biome (Santos and Costa, 2008;Ferraz et al, 2012;Fink et al, 2012). It could also be applied for conservation of threatened species occurring on private lands in other biomes, such as white-browed guan Penelope jacucaca, gray-breasted parakeet Pyrrhura anaca, and rufous-breasted leaftosser Sclerurus scansor cearensis in the caatinga (Farias et al, 2005); and barefaced curassow Crax fasciolata, king vulture Sarcoramphus papa, and black-chested buzzard-eagle Geranoaetus melanoleucus in the cerrado (Lazara, 2011;Posso et al, 2013).…”

Four hurdles for conservation on private land: the case of the golden lion tamarin in Brazil's Atlantic Forest

Many threatened species worldwide rely on patches of remnant vegetation in private landholdings. To establish private reserves that contribute effectively to conservation involves a wide range of complex and interacting ecological, legal, social, and financial factors. These can be seen as a series of successive hurdles, each with multiple bars, which must all be surmounted. The golden lion tamarin, Leontopithecus rosalia, is restricted to the Atlantic Forest biome in the state of Rio de Janeiro, Brazil. This forest is largely cleared. There are many small remnant patches on private lands, able to support tamarins. Local NGO's have successfully used limited funds to contribute to tamarin conservation in a highly cost effective way. We examined the mechanisms by analysing documents and interviewing landholders and other stakeholders. We found that the local NGOs successfully identified landholdings where ecological, legal, social, and some financial hurdles had already been crossed, and helped landholders over the final financial hurdle by funding critical cost components. This cost <5% of the price of outright land purchase. This approach is scalable for golden lion tamarin elsewhere within the Atlantic Forest biome, and applicable for other species and ecosystems worldwide.
