Introduction
My main research goal is to understand major causes and consequences of biodiversity dynamics in natural and human-modified habitats. I am interested in the understanding of ecosystems’ diversity and functioning over multiple spatial scales. I am also curious about how chronic and acute human-impacts affect dynamics of resistance/resilience of biodiversity. At the moment, I have been working on the effects of land use changes on tropical biotas.

Human activities pose a major threat to tropical forest biodiversity and ecosystem services. Although the impacts of deforestation are well studied, multiple land-use and land-cover transitions (LULCTs) occur in tropical landscapes, and we do not know how LULCTs differ in their rates or impacts on key ecosystem components. Here, we quantified the i...

Silva et al. (Land Use Policy, 21 July 2020) offer an assessment of the links between deforestation, livestock production and exports in Brazil. Their analysis, based on relative changes in beef production and pasture area across the whole of Brazil, showed an “apparent decoupling of the link between beef production and deforestation in Brazil”. In...
Article
Comprehension of the benefits involved in mutualisms is crucial to disentangle the role of interactions in the structure and functioning of populations, communities and ecosystems. In ant-plant mutualisms, benefits provided by plants to ants are immediately recognizable, but reverse benefits are less obvious, conditional and accumulate over longer...
