Aplicación del análisis de paleoesfuerzos a regiones plegadas: la compresión terciaria en el sector de Cariñena-Belchite (borde norte de la Cordillera Ibérica)

Estudios Geologicos, 1996
La aplicación del análisis de paleoesfuerzos a las mesoestructuras frágiles (fundamentalmente fallas y picos estilolíticos) del borde norte de la Cordillera Ibérica en el sector de Cariñena-Belchite ha dado como resultado la determinación de cuatro ...

Where water meets rock: Ecological niches and diversity hotspots of hygropetric beetles in the Neotropics

Ecological Entomology, Volume 51, Issue 3, Page 502-516, June 2026.
First continental‐scale synthesis of hygropetric beetle diversity and distribution across Neotropical highlands. Climatic and topographic gradients structure regional assemblages and niche overlap. Ecological convergence suggests adaptation to similar conditions across disjunct regions.

Genetic Diversification in a New Guinean Frog Genus (Mantophryne, Microhylidae) was Driven by Ancient Tectonic Activity and Climate Reorganisation

Ecology and Evolution, Volume 16, Issue 5, May 2026.
Our dated phylogeny and biogeographic analysis of Mantophryne, a microhylid frog genus endemic to New Guinea, revealed origins in the East Papuan Composite Terrane (EPCT) in the late Pliocene. Dispersal and diversification out from the EPCT was driven by tectonic activity and climate reorganisation, creating habitat corridors and isolations in the Late
