Status of the globally threatened forest birds of northeast Brazil

Distribution and conservation of three important bird groups of the Atlantic Forest in north-east Brazil

“…The RPPN Frei Caneca and the RPPN Pedra D'Anta make up a single forest block, being an area of extreme importance for bird conservation in the Neotropical region (MazarBarnett et al, 2005;. These two reserves are also inserted into an IBA (Serra do Urubu), and have formerly hosted Philydor novaesi (Teixeira & Gonzaga, 1983), and Cichlocolaptes mazarbarnetti (Mazar-Barnett & Buzzetti, 2014), which are now likely to be extinct (Brasil, 2014;Pereira et al, 2014).…”

The herpetofauna of the Serra do Urubu mountain range: a key biodiversity area for conservation in the brazilian atlantic forest

“…Other alarming data are concern the bird species of the PEC, this region harbors 14 threatened taxa, 11 of them are endemic to this Atlantic Forest sub-region (Silveira et al, 2003;Silva et al, 2004;Barnett & Buzzetti, 2014;Pereira et al, 2014), and three of them were recently considered extinct in the wild. These are Cichlocolaptes mazarbarnetti, Glaucidium mooreorum and Philydor novaesi (Pereira et al, 2014;MMA, 2014).…”

“…This is the most fragmented and threatened region in the Atlantic Forest, with only 2% (360.455 hectares) of original forest cover left, of which only 3.371 are protected in Conservation Units (Brown & Brown, 1992;Ribeiro et al, 2009). The high level of deforestation since the colonial period, with accelerated rates of deforestation in the 1970's and 1980's, especially for sugar cane plantations and cattle grazing, lead to the actual disturbing level of deforestation in this region (Ranta et al, 1998;Tabarelli et al, 2005;Pereira et al, 2014). Most of the publications on the herpetofauna of the altitudinal seasonal tropical forest of the PEC, deal with species descriptions (e.g., Carnaval & Peixoto, 2004a;Rodrigues et al, 2005;Freire et al, 2010;Passos et al, 2010;Gonçalves et al, 2012); faunal inventories and natural history (e.g., Santos & Carnaval, 2002;Silva et al, 2006;Santana et al, 2008;Moura et al, 2011;Roberto et al, 2015) or geographical distributional records (e.g., Santos & Amorim, 2010;Vilela et al, 2011;Rodrigues et al, 2013a,b).…”

Taxonomical study on a sample of land snails from Nanuque (Minas Gerais, Brazil), with descriptions of three new species

“…Nevertheless, the single forest fragment studied here still harbors a unique fauna and even new species. Our findings in Nanuque are a reminder of how these remnants of Atlantic rainforest might be acting as refuges (e. g., PEREIRA et al 2014), harboring still unknown diversity and perhaps even their own share of endemic species. Despite the regions' flora and fauna being scarcely studied, a high level of biodiversity is thought to be the norm for the broader region encompassing Nanuque and its surroundings and concerns about extinction have already been raised for plant and fish species (CERQUEIRA NETO 2005, SARMENTO-SOARES et al 2007.…”

“…Whether the new species described here have already become extinct remains to be seen, as they may still live unknown and undisturbed in other localities (Leiostracus carnavalescus, for instance, also occurs elsewhere). Still, it is wellknown that many species are becoming extinct before been even known to science (e. g., HAWKSWORTH & COWIE 2013), even in groups prone to greater study and protection efforts, like birds (e. g., PEREIRA et al 2014). Therefore, the situation might be much direr for land and freshwater mollusks, which are deemed the most imperiled group of animals, with the highest extinction rates (LYDEARD et al 2004, RÉGNIER et al 2008.…”
