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.

The Andes as a semi‐permeable geographical barrier: Genetic connectivity between structured populations in a widespread spider

Molecular Ecology, Volume 33, Issue 11, June 2024.
Abstract Geographical barriers like mountain ranges impede genetic exchange among populations, promoting diversification. The effectiveness of these barriers in limiting gene flow varies between lineages due to each species' dispersal modes and capacities. Our understanding of how the Andes orogeny contributes to species diversification comes from well‐

Connectivity conservation planning through deep reinforcement learning

Methods in Ecology and Evolution, Volume 15, Issue 4, Page 779-790, April 2024.
Abstract The United Nations has declared 2021–2030 the decade on ecosystem restoration with the aim of preventing, stopping and reversing the degradation of the ecosystems of the world, often caused by the fragmentation of natural landscapes. Human activities separate and surround habitats, making them too small to sustain viable animal populations or ...

Divergent selection in a Mediterranean pine on local spatial scales

Journal of Ecology, Volume 112, Issue 2, Page 278-290, February 2024.
This study highlights how divergent selection in heterogeneous microenvironments shapes and maintains the functional genetic variation within populations of long‐lived forest tree species, being the first to focus on adaptive genetic divergence between south‐ and north‐facing slopes within continuous forest stands.
