Pervasive gaps in Amazonian ecological research
Carvalho, Raquel L.; Resende, Angelica F.; Barlow, Jos; França, Filipe M.; Moura, Mario R.; Maciel, Rafaella; Alves-Martins, Fernanda; Shutt, JackBiodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain underst...
Diversity of ants on palms in Várzea habitats at amazonia (Hymenoptera: Formici...
Dos-Santos, Iracenir Andrade; Harada, Ana Yoshi; Alves, Suziane Barros; Santos, Marcos Pérsio Dantas; Ribas, Carla RodriguesPalm leaf sheaths provide shelter to numerous groups of vertebrates and invertebrates, both in dry land and periodically flooded environments. Palm leaf sheaths can be considered strategic microhabitats that can be determinant of the survival of ant species inhabiting Amazon islands that undergo periodic flooding. In this work we studied the existence of positive associations between ant and plant communities o...
A social and ecological assessment of tropical land uses at multiple scales: Th...
Gardner, Toby Alan; Ferreira, Joice Nunes; Barlow, Jos; Lees, Alexander C.; Parry, Luke; Guimarães Vieira, Ima Cèlia; Berenguer, ErikaScience has a critical role to play in guiding more sustainable development trajectories. Here, we present the Sustainable Amazon Network (Rede Amazônia Sustentável, RAS): a multidisciplinary research initiative involving more than 30 partner organizations working to assess both social and ecological dimensions of land-use sustainability in eastern Brazilian Amazonia. The research approach adopted by RAS offers...
Gradiente latitudinal de riqueza de espécies de formigas em cerrado: regra de R...
Ribas, Carla RodriguesUniversidade Federal de Lavras; The latitudinal gradient in species richness is a well recognized pattern for several taxa. Although many hypotheses have been proposed to explain this gradient some of them are described as more relevant, such as those related to ambient energy, habitat heterogeneity, evolutionary time and mid-domain effect. The aim of this thesis was to test the existence of the latitudinal gra...
