Ecological Entomology, EarlyView.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 .

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 ...

High Densities of Large Herbivores Rapidly Disrupt Ecosystem Integrity
Global Change Biology, Volume 32, Issue 6, June 2026.Human‐driven increases in large herbivore populations are emerging as a widespread global change pressure on terrestrial ecosystems. Using the largest hectare‐scale herbivore density manipulation experiment conducted to date, we show that high deer densities rapidly disrupt ecosystem integrity across multiple dimensions of biodiversity and ecosystem ...

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 ...
