Snake's exuviae are occasionally reported as nesting material mainly for passerine birds, both in temperate and tropical habitats. Among other explanations, such artifacts might function as warning signals and might deter some potential nest predators. Here we report on the presence of exuviae from the false water cobra (Hydrodynastes gigas) in nin...

One of the great challenges we have today in the Amazon is to conciliate economic development and job creation with the conservation of biodiversity, in this sense, research that aims to evaluate impacts of the productive sector in the Amazon and suggest measures to mitigate these impacts are highly priority. In this sense, our project fits exactly in this issue considering that it will focus on the main impact generated by the Amazon mining industry, which is the suppression of forests. Birds are excellent environmental bioindicators of habitat quality and have strong ecological fidelity to specific habitats, in the most cases with very small territories and home range, so any forest suppression activity will strongly affect these territories and species home ranges of Amazonian birds. So, we have our main question: Where do these birds go after losing their territories and areas of life due to the suppression of the forests where they lived? The most logical answer would be that these simple birds will fly into the forest areas adjacent to the depressed areas and settle in new territories. However, other individuals of the same species may already use these adjacent areas, and this would cause a strong dispute over territories, food, partners, etc. By studying and monitoring the movement of these birds after the loss of their living areas, we will be able to understand how these birds adapt to this new reality, thus being able to evaluate the size of the suppression effect on the survival of these birds and suggesting in the end measures that mitigate the mining activities on forests.

The aim of macroecology is to understand the relationship between ecological variables in large time and space scales and the distribution patterns of organisms. In order to understand the spatial distribution pattern of diversity or the degrees of difference of similarity between areas, beta diversity, several studies have been conducted with a focus on birds inventories and bird community, where patterns have been mainly explained by environmental determinants, and / Or by historical processes and dispersion limits. The mechanisms related to the environmental factors refer to the traditional niches assemblage theory, which assumes that the species differ with some niche differentiation, so that the resources are used differentially by each species, thus, the pattern of Species composition should be determined by environmental characteristics that relate species that can settle in a certain location. On the other hand, mechanisms related to historical processes and limits of dispersion presume that species have the same chance of recruitment, regardless of the competitive superiority of an individual. This is what the Neutral Theory of Biodiversity and Biogeography, proposed by Hubbell, says believes that probabilistic processes in the colonization and extinction of individuals in habitats can explain the differences in composition and relative abundance of the species. For this, the neutral theory assumes that there is no difference between individuals in terms of the per capita rate of life or in their responses to the basic forces acting in the community. Based on these premises this project aims to test the effect of spatial and environmental factors On the patterns of bird distribution in the Amazon.

We focus on biofuel development that impacts forested systems, one of the most controversial types of energy development today (NRC-NAS 2011). This research will advance sustainability science and understanding of impacts of palm oil biofuel development on socio-ecological systems in Brazil. Clean renewable energy policies, biodiversity conservation and economic development are often studied, but generally in isolation. Using an in-depth case study approach, this proposal will fully integrate social and ecological scientific methods. The main benefits of this research will be: 1) understanding rural community level socio-ecological impacts of palm oil expansion; 2) designing policy measures that promote continuous social inclusion and biodiversity-friendly palm oil production; 3) development of new sustainability science indicators and metrics using results from the socioeconomic and biodiversity studies; 4) increasing the research capacity of the Pan American partner institutions for graduate and postgraduate student education specializing in sustainability issues. The goal of this study is to evaluate the impacts of palm oil plantation expansion in the Brazilian Amazon in three interconnected dimensions: environmental, policy and socioeconomic. The study case focal area is the Pará State, northern Brazil. These issues will be assessed from a multi-stakeholder’s perspective, including the views of government agencies, private palm oil companies and affected small landholders. We will use mixed methods of social and natural science research (both qualitative and quantitative) to collect data, specifically evaluating how policies for palm oil crop expansion affect protected areas, biodiversity and local communities (social groups), currently and in the future. These three dimensions will provide a holistic understanding of palm oil based biodiesel impacts in Brazil to suggest means for achieving a sustainable palm oil production in the country. Specifically we intend to: 1) evaluate public policies for the biofuel sector and their relationship to biodiversity and protected areas (legal reserves) policies; 2) define the main drivers for biofuel crop expansion and implications for protected areas and biodiversity conservation as evidenced by species richness and abundance of terrestrial arthropods, aquatic biota, amphibians and birds; 3) assess the impact of palm oil cropping systems for biofuel development on socioeconomic systems. The study will focus on the Pará municipalities included in the Belém Endemism Center such as Moju, Igarapé-Mirim, Tailândia, Tomé-Açu, Acará and Concórdia do Pará, on the basis that these communities concentrate current and projected palm oil plantations according to the Instituto Brasileiro de Geografia e Estatística (IBGE). The project will combine the expertise of natural and social scientists to investigate socioecological impacts of the palm oil biofuel industry currently under development in the one of the most endangered and complex human-modified landscape in Brazilian Amazon.
