Antonini, Yasmine; Machado, Carolina Barros; Galetti Jr., Pedro M.; Oliveira, Marcio Luiz de; Dirzo, Rodolfo; Fernandes, G. WilsonThe knowledge of spatial pattern and geographic beta-diversity is of great importance for biodiversity conservation and interpreting ecological information. Tropical forests, especially the Amazon Rainforest, are well known for their high species richness and low similarity in species composition between sites, both at local and regional scales. We aimed to determine the effect and relative importance of area, ...

Ripple, William J.; Abernethy, Katharine; Betts, Matthew G.; Chapron, Guillaume; Dirzo, Rodolfo; Galetti, Mauro [UNESP]; Levi, Taal; Lindsey, Peter A.Made available in DSpace on 2018-12-11T17:29:58Z (GMT). No. of bitstreams: 0 Previous issue date: 2016-10-19; Terrestrial mammals are experiencing a massive collapse in their population sizes and geographical ranges around the world, but many of the drivers, patterns and consequences of this decline remain poorly understood. Here we provide an analysis showing that bushmeat hunting for mostly food and medicinal...

Fernandes, Geraldo Wilson; Coelho, Marcel Serra; Machado, Ricardo Bomfim; Ferreira, Manuel Eduardo; Aguiar, Ludmilla Moura de Souza; Dirzo, RodolfoO presente trabalho aborda a questão dos ecossistemas e o reflorestamento para a restauração ecológica e a preservação da biodiversidade.
Deep into the mud : ecological and socio-economic impacts of the dam breach in ...
Fernandes, Geraldo Wilson Afonso; Goulart, Fernando F.; Ranieri, Bernardo D.; Coelho, Marcel Serra; Dales, Kirsten; Boesche, NinaWe review the ecological and socio-economic impacts ofthe catastrophic dam failure in Mariana, Brazil. Tailing management practices by Samarco mining company ultimately caused a dam breach that abruptly discharged between 55 and 62millionm3 of tailings into the Doce River watershed. On November 5th, 2015, a tsunami of slurry engulfed the small district of Bento Rodrigues, loading the Doce River and its estuary ...
