The concept of Ecosystem Services (ES) defines the nature benefits in an anthropocentric way for sustainable development goals. However, a conservation dilemma arises from the question of how much the ES cost and which ES should be prioritized in effective landscape planning. Thus, we test how the balance of economic and ecological values can be us...

Reptiles are highly susceptible to climate change, responding negatively to thermal and rainfall alterations mainly in relation to their reproductive processes. Based on that, we evaluated the effects of climate change on climatically suitable areas for the occurrence of snakes in the Atlantic Forest hotspot, considering the responses of distinct r...
Article
Full-text available
A crucial step in any ethological study is to distinguish and classify the observed behavior into categories. The literature on anuran antipredator mechanisms is largely scattered and descriptive due to the opportunistic nature of the observations and the lack of a simple, widely accepted classification scheme. We propose an explanatory classificat...
Article
Full-text available
Climate refuges have been used by several species over historical climate change. Ectothermic species often display good models for climate change studies because they are highly sensitive to temperature. Analysis of species loss with ecosystem and evolutionary values helps to understand environmental processes and climate change consequences. We d...
Article
Full-text available
Nestedness among species assemblages implies that sites of lower species richness are subsets of richer sites in a regional species pool. This nestedness is a reflection of a non-random process of species loss as a consequence of factors that promote the disaggregation of assemblages. The impoverishment of assemblage diversity is more often observe...
