The ancient Maya and the modern forest

open access: yesBiotropica, Volume 57, Issue 1, January 2025.
After the “collapse” of the ancient Maya c. 1100 years ago, forest grew back over large areas of the Maya Lowlands in Mesoamerica. The modern forest may reflect ancient Maya substrate changes and forest management practices. Based on evidence, we conclude that these legacies in the modern forest probably vary from significant to negligible across the ...

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

open access: yesPLANTS, 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.

Bats and Mayan temples: Bat diversity and the potential for conservation of archeological zones in Yucatan, Mexico

open access: yesBiotropica, Volume 56, Issue 4, July 2024.
The role of archeological zones in biological conservation has been highlighted because they restrict land‐use change, size, and maintenance of upstanding vegetation. We found 23 species from six families and seven guilds, representing 53% of all bat species known from the Yucatan state, including two endangered species for Mexico.
