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.

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.

Histologic, metabolomic, and transcriptomic differences in fir trees from a peri‐urban forest under chronic ozone exposure

Ecology and Evolution, Volume 14, Issue 5, May 2024.
Urbanization alters ecosystems and evolutionary processes. Processes like air pollution by tropospheric ozone contribute to the decline of urban and peri‐urban ecosystems, such as Abies religiosa forests in the peripheral mountains southwest of Mexico City.

Plant phylogenetic diversity influences arthropod communities in tropical forest restoration plots

Biotropica, Volume 56, Issue 3, May 2024.
We assessed the impact of plant phylogenetic diversity on arthropod communities in 12 experimental restoration plots with either high or low plant phylogenetic diversity. Arthropods with different feeding habits (herbivores, predators, pollinators, and detritivores) were collected after 1 and 3 years and were identified as morphospecies or operational ...
