Mangrove Pollinator Functional Diversity Decreases With Patch Size and Landscape Anthropization
Biotropica, Volume 57, Issue 5, September 2025.This study explores how land use changes impact pollinator diversity in mangrove ecosystems, focusing on the effects of patch size and landscape anthropization on pollinators with different functional traits. Results show that smaller mangrove patches can support higher pollinator abundance, richness, and diversity; however, overall pollinator metrics ...

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.

Genomic signatures of past megafrugivore‐mediated dispersal in Malagasy palms
Journal of Ecology, Volume 112, Issue 7, Page 1583-1598, July 2024.Our results suggest that the legacy of megafrugivores regularly achieving long dispersal distances is still reflected in the population genetics of palms that were formerly dispersed by such animals. Furthermore, low genetic differentiation was possibly maintained after the megafauna extinctions through alternative dispersal (e.g.
