Efecto de los nidos de Acromyrmex lobicornis (Formicidae: Myrmicinae) sobre la descomposición de hojarasca, en el desierto del Monte

Boletín de la Sociedad Argentina de Botánica, 2018
La descomposición es un proceso fundamental de los ecosistemas. En ambientes áridos y semiáridos, estos procesos se ralentizan debido a las condiciones climáticas desfavorables para la actividad microbiana, por lo que, organismos como las hormigas se ...

Spiders in the mosaic: How habitat heterogeneity and structure drive local spider diversity in a Mediterranean forest

Ecological Entomology, Volume 51, Issue 4, Page 810-826, August 2026.
We assessed alpha‐ and beta‐diversity patterns of spiders across different forests and across vegetation layers (ground, shrub, low canopy) at local spatial scales across various Mediterranean forest types. Across forests, alpha‐diversity increased with habitat heterogeneity, which also drove beta‐diversity patterns across plots .

Where We're Going, We Won't Need Eyes to See: Distributional Range Size Drivers of European Subterranean Spiders

Journal of Biogeography, Volume 53, Issue 5, May 2026.
ABSTRACT Aim Understanding why closely related species can have drastically different distributional range sizes is a fundamental question in biology. However, answering this question is challenging due to the multiple inter‐related factors that shape species distributions, particularly in continental regions, where unclear ecological and geographic ...

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

Journal 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

Applied 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)

Systematic 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.
