Ecology and Evolution, Volume 15, Issue 8, August 2025.This study investigates pollen dispersal, vertical stratification of gene flow, and spatial genetic structure in the bat‐pollinated liana Marcgravia longifolia in a western Amazonian forest. Flowers are produced from the forest floor to the canopy, allowing analysis of pollination across strata.

Ecology and Evolution, Volume 15, Issue 5, May 2025.We aim to uncover the current and historic effective dispersal distances and characterize fine‐scale genetic structure in the forest tree species Nothofagus pumilio. Short seed dispersal distances mean N. pumilio distribution expansion capacity may be limited, especially in the context of global change.

Revista de Biología Tropical, 2008 Dispersal capabilities determine and maintain local gene flow, and this has implications for population persistence and/or recolonization following environmental perturbations (natural or anthropogenic), disease outbreaks, or other demographic collapses.

COSST: A tool to facilitate seed provenancing for climate‐smart ecosystem restoration
Journal of Applied Ecology, Volume 62, Issue 3, Page 677-688, March 2025.Our tool can guide where to source seeds for species lacking range‐wide information on genetic structure, which is the case for a substantial proportion of the tropical flora, where ecosystem restoration is of paramount importance. Abstract Selecting the best seed sources is a key step in ecological restoration planning especially under climate change.

Conservation Biology, Volume 38, Issue 4, August 2024.Abstract Conservation translocations are an important conservation tool commonly employed to augment declining or reestablish extirpated populations. One goal of augmentation is to increase genetic diversity and reduce the risk of inbreeding depression (i.e., genetic rescue).

PLANTS, PEOPLE, PLANET, Volume 6, Issue 4, Page 834-846, July 2024.The genetic variation of crop wild relatives will be key for our survival, as environmental change represents an increasing global threat for agriculture and food security. Cucurbita lundelliana and Cucurbita okeechobeensis subsp. martinezii are wild relatives of cultivated squashes and pumpkins that could be used for crop improvement.
