Assessing population viability and management strategies for species recovery of the critically endangered Puerto Rican parrot

open access: yesAnimal Conservation, Volume 28, Issue 1, Page 104-118, February 2025.
Recovery of endangered species is challenging, especially when it involves reintroduction and dynamic environmental conditions. We developed a population viability analysis (PVA) for the critically endangered Puerto Rican parrot to evaluate current status and potential future management strategies.

Tree Diversity Increases Carbon Stocks and Fluxes Above—But Not Belowground in a Tropical Forest Experiment

open access: yesGlobal Change Biology, Volume 31, Issue 2, February 2025.
We examined the potential of mixed‐species planted forests compared to monospecific forests to act as a nature‐based solution to climate change mitigation through carbon sequestration. By analysing multiple carbon stocks and fluxes over 16 years in the world's oldest tropical tree diversity experiment, we found that planted forests with five tree ...
