American Journal of Botany, Volume 110, Issue 5, May 2023., 2023 Abstract Premise Oceanic islands offer the opportunity to understand evolutionary processes underlying rapid diversification. Along with geographic isolation and ecological shifts, a growing body of genomic evidence has suggested that hybridization can play an important role in island evolution.

Journal of Ecology, Volume 110, Issue 10, Page 2308-2320, October 2022., 2022 Our results provide important insights into the responses of semiarid annual plant communities under a climate change scenario. Experimental rain exclusion consistently decreased diversity (taxonomic and functional) but to a lesser extent than interannual rain patterns, that result in deep diversity losses during drought events but rapid recovery in ...

Recruitment limitation in three large‐seeded plant species in a tropical moist forest
Biotropica, Volume 54, Issue 2, Page 418-430, March 2022., 2022 Recruitment limitation results from three mechanisms: (i) lack of seed sources (i.e., source limitation), (ii) failure of available seeds to reach recruitment sites (i.e., dispersal limitation), and (iii) failure of arrived seeds to establish at a location (i.e., establishment limitation).

PLANTS, PEOPLE, PLANET, Volume 3, Issue 3, Page 238-248, May 2021., 2021 Tropical dry forests (TDF) underpin the wellbeing of millions, mostly rural populations; yet have suffered from severe clearing in Colombia, triggering cascading effects such as desertification. By engaging scientists, society, and institutions in the establishment of platforms for monitoring biodiversity and ecosystem functioning, crucial knowledge ...
