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 ...

The potential influence of genome‐wide adaptive divergence on conservation translocation outcome in an isolated greater sage‐grouse population

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).

High levels of genetic variation and differentiation in wild tropical gourds provide a novel resource for cucurbit crop improvement

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.

Identificando señales de evolución no estocástica en la morfología craneofacial de poblaciones humanas modernas

Revista Argentina de Antropología Biológica, 2012
Las poblaciones humanas varían significativamente en su morfología craneana. Aún se debate hasta dónde ésta variabilidad se ha acumulado a través de procesos neutrales (e.g. deriva genética) o bien por efecto de la selección natural.
