Islands in a green ocean: spatially structured endemism in Amazonian white-sand vegetation

Flavio Costa, Mario Terra-Araújo, Charles Zartman, Cintia Cornelius, Fernanda Carvalho, Michael Hopkins, Pedro Viana, Eduardo Prata & Alberto Vicentini
Here, we examine the influence of the spatial distribution of open White-Sand Campina (WSC) in the Amazon on the species richness and beta-diversity of their vascular plants. It is well known that beta-diversity tends to increase with geographical distance, but the influence of habitat insularity on floristic composition and endemism is still unclear. We surveyed WSC in Central and Southwestern Amazon, generating lists of species occurrences by rapid-inventory techniques to evaluate the influence of island...

Variation in the production of plant tissues bearing extrafloral nectaries explains temporal patterns of ant attendance in Amazonian understory plants

Anselmo Nogueira, Fabricio Baccaro, Laura Leal, Pedro Rey, Lúcia Lohmann & Judith Bronstein
1. Information on direct and indirect drivers of temporal variation in ant-plant interactions is scarce, compromising our ability to predict the functioning of these ecologically important interactions. 2. We investigated the roles of precipitation, ant activity, abundance of young plant tissues bearing extrafloral nectaries (EFNs), and EFN phenotypes in the establishment of EFN-mediated ant-plant interactions throughout the year in Amazonia, Brazil. We hypothesized that the frequency of ant-plant interactions follows a predictable seasonal pattern, being...

Data from: Intraspecific and interspecific trait variability in tadpole metacommunities from the Brazilian Atlantic rainforest

Mainara Xavier Jordani, Nicolas Mouquet, Lilian Casatii, Marcelo Menin, Denise De Cerqueira Rossa-Feres & Cécile H. Albert
1. A better understanding of species coexistence and community dynamics may benefit from more insights on trait variability at the individual and species levels. 2. Tadpole assemblages offer an excellent system to understand the relative influence of intra- and interspecific variability on community assembly, due to their high phenotypic plasticity, and the strong influence that environmental variables have on their spatial distribution and individual performance. 3. Here we quantified the intra- and interspecific components of...

Surveys of crocodilians in the hydroelectric dam, Brazilian Amazonia

Zilca Campos, Fábio Muniz, Guilherme Mourão & William Magnusson
We counts caimans in the Madeira River, before (2010-2011) and after (2012-2014, 2016-2019) hydroelectric dam.
