Evidence of introgression amid phylogenetic conflict in Brachyotum, a plant radiation from the Tropical Andes

open access: yesAmerican Journal of Botany, Volume 113, Issue 6, June 2026.
Abstract Premise The species‐rich flora of Tropical Andes underwent multiple rapid and recent diversifications, yet resolving their evolutionary histories remains challenging despite increasing phylogenomic data. Here, we examined phylogenomic conflict in Brachyotum (Melastomataceae) to identify sources preventing its resolution.

Local canopy cover, shade tree identity and landscape tree cover shape leaf‐cutter ant nest density and herbivory in cacao agroforestry systems

open access: yesJournal of Applied Ecology, Volume 63, Issue 4, April 2026.
Our findings provide practical guidance for agroforestry management by demonstrating that intercropping with selected species can mitigate damage from leaf‐cutter ants in cacao agroforests. At the landscape scale, high tree cover was associated with low herbivory rates, emphasising the need to maintain or restore forested habitats.

Surveillance of ash trees under multiple threats: Integrating emerald ash borer and ash dieback dynamics with stakeholder behaviour

open access: yesJournal of Applied Ecology, Volume 63, Issue 3, March 2026.
Tree‐health policies must balance identifying likely entry points and deployment of traps, targeted information campaigns and surveillance subsidies for land managers. Our unique, cross‐disciplinary approach can be applied to other pest/pathogen systems to inform tree‐health plans and how to balance resources.

Trait‐based species selection for restoration: A case study from tropical landscapes dominated by bracken

open access: yesJournal of Applied Ecology, Volume 63, Issue 1, January 2026.
Our results can be used by stakeholders to select the species best suited for active restoration projects in bracken‐dominated areas throughout the tropical region. Furthermore, our trait‐based approach, which considers seedling performance in disturbed areas, can serve as a guide for species selection in restoration programmes in other disturbed ...
