Hyperdominant Trees Reveal Savanna Vulnerability Under Climate Change. [PDF]

Glob Chang Biol
The Brazilian Cerrado's forest structure relies disproportionately on just 30 hyperdominant tree species, which represent 50% of all individuals despite accounting for only 2% of species richness. This study evaluates their vulnerability under climate change scenarios for 2100.

Beyond Carbon: The Contributions of South American Tropical Humid and Subhumid Forests to Ecosystem Services

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.
