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.

Seed Traps Differ in Species Numbers, Seed Densities and Contamination but Mostly Do Not Reflect Grazing in a Pampa Grassland

open access: yesApplied Vegetation Science, Volume 29, Issue 2, April/June 2026.
Ground traps are more effective than adhesive traps in measuring seed rain species richness and density. They also allow to more closely resemble the seed production of the surrounding vegetation. Management‐driven differences in the vegetation were not reflected by the seed rain of any trap type, but the advantages and disadvantages of different trap ...

Alone no more—Integrative taxonomy of New Zealand odd‐clawed spiders challenges the monotypy of Pianoa and Gradungula (Araneae: Gradungulidae)

open access: yesSystematic Entomology, Volume 51, Issue 1, January‐March 2026.
Taxonomic revision of New Zealand Gradungulidae reveals unexpected northern South Island diversity through integrated molecular phylogenetics and targeted field sampling. Two new species formally described — Gradungula kahurangi sp. nov. and Pianoa civis sp. nov. — with revised male genitalia diagnoses for all three New Zealand genera.

Intraspecific plant chemodiversity at plot level has contrasting effects on arthropod functional groups

open access: yesFunctional Ecology, Volume 39, Issue 12, Page 3732-3750, December 2025.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Plant chemistry mediates interactions between plants and their environment. While intraspecific chemodiversity at the individual plant level is well studied, the effects of chemodiversity at the plant community level on arthropod interactions need more attention.

Composición de hormigas (Hymenoptera: Formicidae) en dos microabitats de un bosque pie-montano

open access: yes, 2010
La hipótesis de la heterogeneidad establece que el número de especies en un área es proporcional al de microhábitats que abarca. El descubrimiento de hormigas que anidan preferentemente en bancos de arcilla de los bosques montanos neotropicales generó la

Ecosystem services provided by spiders

open access: yesBiological Reviews, Volume 100, Issue 6, Page 2217-2236, December 2025.
ABSTRACT Spiders, ubiquitous and abundant predators in terrestrial ecosystems, often are the subjects of an unjust negative perception. However, these remarkable creatures stand as unsung heroes within our ecosystems, contributing a multitude of ecosystem services critical to human well‐being.
