Exploring ecohydrology through the lens of local fishers in the Bolivian Amazon

Ecosphere, Volume 17, Issue 4, April 2026.
Abstract The natural flow regimes of Andean‐Amazon tributaries play a vital role in sustaining their rich biodiversity and productive local fisheries, but ongoing and proposed alteration of river flow regimes by large dams threatens to negatively impact river ecosystems. Despite its importance, our understanding of how hydrologic variability influences

Unravelling the drivers of island species richness in tropical savannas

Journal of Ecology, Volume 114, Issue 4, April 2026.
Murundu island area explains a substantial proportion of the variation in tree and herb richness, consistent with Island Biogeography Theory. On average, a 10% increase in island size corresponds to increases of seven tree species and 7.8 herb species.

Patterns of Interploidy Admixture in Polyploid Complexes: Insights From Thymus Sect. Mastichina (Lamiaceae)

Molecular Ecology, Volume 35, Issue 3, February 2026.
ABSTRACT Understanding gene flow between ploidy levels in polyploid complexes is essential for species delimitation and conservation. This study explores evolutionary dynamics in the polyploid complex Thymus sect. Mastichina (Lamiaceae), comprising three taxa: T. mastichina subsp. mastichina, T. mastichina subsp.

Local knowledge enhances the sustainability of interconnected fisheries

Journal of Applied Ecology, Volume 63, Issue 1, January 2026.
Our modelling approach allows managers to compare alternative conservation strategies under different socio‐ecological scenarios, highlighting trade‐offs and guiding investment of effort and resources. While immediately valuable for pirarucu management in the Middle Juruá, the framework scales across tiers of applicability, each requiring progressively

The influence of hydrological seasonality and land use and cover on the relationship between dissolved organic carbon and carbon dioxide along a karst‐draining large tropical river

Limnology and Oceanography, Volume 70, Issue 10, Page 2858-2871, October 2025.
Abstract The partial pressure of carbon dioxide (pCO2) in rivers is influenced by carbonate weathering, soil CO2, photosynthesis, and the mineralization of dissolved organic carbon (DOC). In tropical regions, elevated temperatures intensify these processes. However, their seasonal dynamics remain poorly understood in large karst‐draining rivers.

Breaking the Caribbean Plate: Subduction Initiation Beneath the Northern Margin of Panama

Geophysical Research Letters, Volume 52, Issue 18, 28 September 2025.
Abstract The initiation of subduction zones is a poorly understood but core plate tectonic process. One unknown is how and under what conditions previously contiguous plates break. Here we present a comprehensive assessment of the Northern Panama Subduction Zone (NPSZ) where the Caribbean Plate is subducting to the SSW beneath Panama.
