Sources of variation in plant chemical diversity: Lessons from Malagasy Ficus

American Journal of Botany, Volume 112, Issue 9, September 2025.
Abstract Premise Plants produce a tremendous variety of secondary compounds that are crucial to interspecific and intraspecific interactions and for adaptation to environmental changes. This chemical diversity has been attributed to multiple factors, including interactions with herbivores or pollinators, tissue‐specific needs, and evolutionary ...

Leaf nodule endosymbiotic Burkholderia confer targeted allelopathy to their Psychotria hosts

Scientific Reports, 2021
After a century of investigations, the function of the obligate betaproteobacterial endosymbionts accommodated in leaf nodules of tropical Rubiaceae remained enigmatic. We report that the α-d-glucose analogue (+)-streptol, systemically supplied by mature

Late 21st‐Century Climate and Land Use Driven Loss of Plant Diversity in African Mountains

Global Change Biology, Volume 31, Issue 9, September 2025.
By the end of this century, many African mountain plants may lose large parts of their suitable habitats as the climate warms and land use changes. Even under a sustainable pathway limiting warming to under 2°C, nearly half of the 607 studied species are projected to contract their ranges, with losses even greater under higher emission scenarios ...

A Short‐Read Amplicon Sequencing Protocol and Bioinformatic Pipeline for Ecological Surveillance of Dipteran Disease Vectors

Molecular Ecology Resources, Volume 25, Issue 6, August 2025.
ABSTRACT Vector control remains an important strategy worldwide to prevent human infection with pathogens transmitted by arthropods. Vector control strategies rely on accurate identification of vector taxa along with vector‐specific biological indicators such as feeding ecology, infection prevalence and insecticide resistance.

Disentangling the Evolutionary History of the Woody Species in Earth's Most Diverse Tropical Savanna

Journal of Biogeography, Volume 52, Issue 8, August 2025.
ABSTRACT Aim We investigate the evolutionary structure of vegetation assemblages in the Cerrado Domain, the main extent of savanna in the American Tropics, a biodiversity hotspot, to understand the role of ecological and geographical factors in constraining plant diversification and shaping biogeographic patterns across this complex mosaic of ...

Mountain colonization precedes shifts away from bee pollination in Melastomataceae

New Phytologist, Volume 247, Issue 3, Page 1474-1492, August 2025.
Summary Shifts among different groups of pollinators are central in the evolution of flowering plants, yet mechanisms underlying pollinator shifts remain unclear. Environment‐induced reduction in pollinator availability and hence efficiency may destabilize ancestral plant–pollinator interactions and trigger shifts to new, more efficient pollinators ...
