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.

Strong genetic differentiation but limited niche partitioning in a sympatric species pair separated by an allochronic reproductive barrier

open access: yesSystematic Entomology, Volume 51, Issue 2, April‐June 2026.
Sympatric sister species demonstrate substantial geographic and host overlap, with ecological analyses only finding subtle microecological variation in habitat use. Molecular analyses reveal clear genetic differentiation with no evidence of hybridization, suggesting strong reproductive isolation between species. Differences in time‐of‐day mating appear

Biodegradable Coatings with Essential Oils for Combating Papaya Anthracnose: State of the Art and Perspectives

open access: yesFood Bioengineering, Volume 5, Issue 1, Page 138-151, March 2026.
ABSTRACT Papaya (Carica papaya L.) production and marketability are strongly constrained by postharvest diseases, with anthracnose caused by Colletotrichum spp. representing the most significant threat. Traditional control relies on synthetic fungicides, which, although effective, face challenges such as the development of pathogen resistance ...

Patterns of Tree Species Abundance and Diversity on Urban Sidewalks in Macapá, Amapá, Brazil

open access: yesEcological Research, Volume 41, Issue 2, March 2026.
This study presents the first systematic inventory of street trees in Macapá, Northeastern Brazilian Amazon. Results reveal a dominance of exotic and fruit‐bearing species, low tree density, and a replacement of large canopy trees by smaller ones, indicating potential losses in ecosystem services and the need for more biodiversity‐focused afforestation
