Reviews of Geophysics, Volume 60, Issue 4, December 2022., 2022 Abstract Tropical forests are recognized for their role in providing diverse ecosystem services (ESs), with carbon uptake the best recognized. The capacity of tropical forests to provide ESs is strongly linked to their enormous biodiversity. However, causal relationships between biodiversity and ESs are poorly understood.

An alert system for Seasonal Fire probability forecast for South American Protected Areas
Climate Resilience and Sustainability, Volume 1, Issue 1, February 2022., 2022 We considered five variables that represent the anthropogenic and climatological conditions that increase the probability of fire occurrence. The anthropogenic components of the forecast are the (i) trend in the number of active fires over the past three years and (ii) accumulated number of active fires over the same period.
