Scaling from microsite to landscape to resolve litter decomposition dynamics in globally extensive drylands

open access: yesFunctional Ecology, Volume 40, Issue 9, Page 2726-2736, September 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Decomposition is the transformation of dead organic matter into its inorganic constituents. In most biomes, decomposition rates can be accurately predicted with simple mathematical models, but these models have long under‐predicted decomposition in globally extensive ...

Uncovering correlates of decline and critical refuges for a threatened terrestrial mammal

open access: yesConservation Biology, Volume 40, Issue 4, August 2026.
Abstract Globally, the geographic ranges of numerous species are contracting. Identifying spatiotemporal patterns of threat impact can illuminate why species decline in some parts of their range but persist in others. We developed a correlative approach to identify species’ response thresholds and locate ecological refuge areas associated with ...

Coping with change: Interactive effects of anthropogenic change influence the breeding success and survival of a desert‐dwelling cooperative breeder

open access: yesFunctional Ecology, Volume 40, Issue 7, Page 2038-2052, July 2026.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Habitat modification and climate change are major threats to biodiversity. Using 38 years of data (1985–2023), we examined their combined influence on a desert‐dwelling cooperative breeder's reproductive success and projected the likely magnitude of future effects of ...

Una evaluación de las temperaturas medias seculares durante el último milenio a partir de las desviaciones del gradiente geotérmico

open access: yes, 1982
Mediante una ligera modificación de las ecuaciones propuestas por Cermak (1971), con la que se filtra el «ruido de fondo» en las desviaciones de los gradientes, se determinan las temperaturas medias seculares entre los siglos XI y XIX, inclusives, a ...
