Genomics and morphometry of herbarium specimens elucidate the origin of the Cape Verde date palm (Phoenix atlantica A.Chev.) and highlight its agronomic potential

PLANTS, PEOPLE, PLANET, Volume 7, Issue 5, Page 1358-1371, September 2025.
As climate change accelerates, breeding resilient crops is urgent. The date palm (Phoenix dactylifera L.), a crucial 18 billion USD fruit crop, underpins North African and West Asian oasis agroecosystems. This study investigates the genetics and morphology of its closest wild relative, the endemic and endangered Cape Verde date palm (Phoenix atlantica ...

Thermotolerance in Miniature: Heat Resilience of Moss Propagules From Brazilian Ferruginous Rocky Outcrops

Austral Ecology, Volume 50, Issue 9, September 2025.
ABSTRACT Harsh environments present substantial challenges to most organisms, making survival and thriving difficult. Such conditions often include extreme temperatures, intense radiation, strong winds, and very low or high humidity levels, resulting in a limited availability of resources like water and nutrients.

Terroir and rootstock effects on leaf shape in California Central Valley vineyards

PLANTS, PEOPLE, PLANET, Volume 7, Issue 4, Page 1110-1122, July 2025.
The innumerable effects of terroir—including climate, soil, microbial environment, biotic interactions, and cultivation practice—collectively alter plant performance and production. A more direct agricultural intervention is grafting, in which genetically distinct shoot and root genotypes are surgically combined to create a chimera that alters shoot ...

Temporal Dynamics of a Neotropical Plant‐Hummingbird Interaction Network

Austral Ecology, Volume 50, Issue 7, July 2025.
Using an unprecedented sampling effort we evaluated network structure and dynamics of plant‐hummingbird interactions over 1 year in the Brazilian hyperdiverse Campos Rupestres. Network structure presented remarkable temporal change, showing that tropical communities can also be strongly influenced by climate.

Grazing Modulates the Multiscale Spatial Structure of Dryland Vegetation

Global Change Biology, Volume 31, Issue 7, July 2025.
We studied how grazing pressure affects plant spatial patterns in drylands by using satellite images, field plant size and abundance data, and a mathematical model. We found that increasing grazing pressure has opposite effects on vegetation spatial structure to those of aridity, which might be explained by the fact that grazing decreases plant size ...
