Carbon Emissions From Low‐Order Streams in a Tropical, High‐Elevation, Peatland Ecosystem Are Mediated by Catchment Morphology

open access: yesWater Resources Research, Volume 61, Issue 4, April 2025.
Abstract Inland waters emit large amounts of carbon and are key players in the global carbon budget. Particularly high rates of carbon emissions have been reported in streams draining mountains, tropical regions, and peatlands. However, few studies have examined the spatial variability of CO2 concentrations and fluxes occurring within these systems ...

Conservation and management implications of the effects of wildfire on a threatened Eastern Iberian Reed Bunting (Emberiza schoeniclus witherbyi) population

open access: yesIbis, Volume 167, Issue 1, Page 196-211, January 2025.
Wetland degradation worldwide has led to fragmentation and isolation of diminished populations that are now more vulnerable to disturbance. Wildfires affecting wetlands can have major impacts on vegetation structure and associated waterbird communities, but rapid recovery of the initial state of vegetation cover after fire due to fast emergent ...

Blind shots: non‐natural mortality counteracts conservation efforts of a threatened waterbird

open access: yesAnimal Conservation, Volume 27, Issue 3, Page 293-307, June 2024.
The assessment of the marbled teal population reinforcement programme in Spain carrying out releases of captive‐bred birds showed that 60% of the mortality is due to non‐natural causes, mostly illegal shooting. To establish a self‐sustaining population, non‐natural mortality should be reduced by 40% and management measures such as prosecution of ...
