Atlantic rainforest's jaguars in decline
(Science, 2013-01-01) [Carta]
Ecology and conservation of the jacutinga Pipile jacutinga in the Atlantic Forest of Brazil
(Biological Conservation, 1997-10-01) [Artigo]
The jacutinga Pipile jacutinga was formerly one of the most abundant game bird cracids in the Atlantic forest of Brazil. Nowadays this species is vulnerable to extinction due to hunting and habitat loss. The ecology of the ...
Functional Redundancy and Complementarities of Seed Dispersal by the Last Neotropical Megafrugivores
(PLOS ONE, 2013-02-07) [Artigo]
Background: Functional redundancy has been debated largely in ecology and conservation, yet we lack detailed empirical studies on the roles of functionally similar species in ecosystem function. Large bodied frugivores may ...
Differential seed germination of a keystone palm (Euterpe edulis) dispersed by avian frugivores
(Journal of Tropical Ecology, 2012-11-01) [Artigo]
The effectiveness of seed dispersal by vertebrates has been analysed by examining both quantitative and qualitative components (Jordano & Schupp 2000, Schupp et al. 2010). While the quantitative component is relatively ...
Atlantic forest fragmentation and genetic diversity of an isolated population of the Blue-manakin, Chiroxiphia caudata (Pipridae), assessed by microsatellite analyses
(Revista Brasileira de Ornitologia, 2006-03-01) [Artigo]
Habitat fragmentation is predicted to restrict gene flow, which can result in the loss of genetic variation and inbreeding depression. The Brazilian Atlantic forest has experienced extensive loss of habitats since European ...
Mistletoes Play Different Roles in a Modular Host-Parasite Network
(Biotropica, 2012-03-01) [Artigo]
Antagonistic interactions between host plants and mistletoes often form complex networks of interacting species. Adequate characterization of network organization requires a combination of qualitative and quantitative data. ...
Conservation puzzle: Endangered hyacinth macaw depends on its nest predator for reproduction
(Biological Conservation, 2008-03-01) [Artigo]
In the Pantanal wetlands of Central Brazil, the endangered hyacinth macaw (Anodorhynchus hyacinthinus), the largest psitacid in the world, makes its nest almost exclusively in natural hollows found in the manduvi tree ...
Using post-release monitoring data to optimize avian reintroduction programs: a 2-year case study from the Brazilian Atlantic Rainforest
(Animal Conservation, 2011-12-01) [Artigo]
Post-release monitoring data of reintroduced captive-bred birds can be utilized to help optimize future avian reintroduction programs. We present a case study of broad interest to reintroduction and conservation biologists ...
Estimating interaction credit for trophic rewilding in tropical forests
(Philosophical Transactions of the Royal Society B: Biological Sciences, 2018-12-05) [Artigo]
Trophic rewilding has been suggested as a restoration tool to restore ecological interactions and reverse defaunation and its cascading effects on ecosystem functioning. One of the ecological processes that has been ...
Local Extinctions of Primates: Demographic and Genetic Effects on Vegetation
(Folia Primatologica, 2013-01-01) [Resumo]
