Development of Holocene lacustrine microbialites on the Iberian Peninsula: Insights into environmental and depositional controls using X‐ray CT and petrography

open access: yesSedimentology, Volume 73, Issue 4, Page 1148-1184, June 2026.
ABSTRACT Microbial mats and microbialites are common in modern and ancient saline lacustrine environments and are highly responsive to biological and environmental factors. As such, they represent important sources of high‐resolution environmental data across a wide range of geological time. Nonetheless, interpretation of fossil mats is non‐trivial due

Role of Complex Crustal and Basinal Structures in Onset of an Intracratonic Rift System: An Example From the Onshore Potiguar Basin, Brazilian Equatorial Margin

open access: yesBasin Research, Volume 38, Issue 2, March–April 2026.
Schematic evolution model of the Onshore Potiguar Basin, illustrating the role of complex crustal and basinal structures in the onset of this intracratonic rift system in NE Brazilian Equatorial Margin. Red arrows indicate the extensional direction and coloured areas on the surface are the Self‐Organizing Maps populations related to crystalline ...

Biome Specialisation in Squirrels: Phylogenetic and Geographic Patterns

open access: yesJournal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim Habitat breadth shapes species' responses to environmental change and influences large‐scale biodiversity patterns. According to Vrba's resource‐use hypothesis, biome specialists (inhabiting a single biome) exhibit higher speciation rates than generalists due to increased population isolation during habitat fragmentation, generally ...

Discusión de modelos para la corteza y manto superior en la zona Sur del área Centroibérica, basados en anomalías gravimétricas

open access: yesEstudios Geologicos, 1986
Con el fin de realizar una interpretación en profundidad del origen del vulcanismo de Campo de Calatrava, se efectúa un perfil gravimétrico, elaborándose varios modelos bidimensionales de Corteza y Manto superior. Posteriormente se discuten las distintas

The division of food space among mammalian species on biomes

open access: yesEcography, Volume 2025, Issue 10, October 2025.
Understanding how species' ecological partitioning functions across biomes is fundamental to macroecology and conservation biology. Here, we examine the global distribution of dietary strategies in terrestrial mammals, focusing on how biome specialization modulates trophic diversity and structure at a broad geographical scale.

Mode of Continental Thinning and Breakup Along the North Iberian‐Armorican Conjugate Margins in the Bay of Biscay

open access: yesJournal of Geophysical Research: Solid Earth, Volume 130, Issue 10, October 2025.
Abstract Continental breakup involves multiple extension styles; each linked to unique structural and sedimentary processes. High‐angle, low‐angle, listric and antilistric normal faults develop at different stages and positions during rifting. The Bay of Biscay and its margins, a prototypical example of magma‐poor rifted margins during Jurassic ...
