Moth Communities Reveal High Stability Despite Ongoing Compositional Shifts Over Five Years Following Hurricane Disturbance

Ecology and Evolution, Volume 15, Issue 10, October 2025.
We examined the temporal dynamics and ecological stability of tropical forest moth communities using a unique dataset spanning 6 months before and up to 5 years after two extreme hurricanes. While abundance and richness recovered within 2 years, species composition continued to shift, indicating ongoing reassembly with a directional trajectory toward ...

Role of science and scientists in public environmental policy debates: The case of EU agrochemical and Nature Restoration Regulations

People and Nature, Volume 7, Issue 8, Page 1772-1788, August 2025.
Abstract Halting biodiversity loss, mitigating global warming and maintaining the long‐term viability of rural and urban areas requires urgent policy action. However, environmental policies often trigger resistance and highly polarised public debates, with some actors employing pseudo‐scientific claims.

RESISTENCIA MECÁNICA DE LOS TABLEROS DE DENSIDAD MEDIA: PARTE 2: MODELO POLINOMIAL ORTOGONAL PARA ESTIMAR LA RESISTENCIA A LA FATIGA EN LA TRACCIÓN

Maderas. Ciencia y tecnología, 2004
Tableros de Densidad Media (MDF), son compositos a partir de madera, ampliamente utilizados en varias aplicaciones industriales, inclusive aquéllas estructurales que dependen de la fatiga. Aun así, sus aspectos relativos a la fatiga han sido comúnmente ignorados. Por lo tanto, el objetivo de este trabajo es presentar un modelo polinomial ortogonal para

Hydraulic Strategies Modulate Forest Productivity Responses to Hotter Droughts

Global Change Biology, Volume 31, Issue 7, July 2025.
Climate change is increasing the occurrence of extreme events like hotter droughts, which threaten forest health and carbon storage. We studied forests in central Spain to understand how drought intensity, frequency, and duration affect forest productivity.

Amazonian conservation across archipelagos of Indigenous territories

Conservation Biology, Volume 39, Issue 2, April 2025.
Abstract Indigenous stewardship is essential to the conservation of biocultural diversity, yet conventional conservation models often treat Indigenous territories (ITs) as homogeneous or isolated units. We propose that archipelagos of Indigenous territories (AITs), clusters of ITs that span geographies but are connected through shared cultural or ...
