Monitoring mercury across the National Wildlife Refuge System using a biosentinel approach

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 4, May 2026.
We measured mercury concentrations in 1,356 dragonfly larvae collected from 30 National Wildlife Refuges across the United States and found wide variability among refuges, spanning the full range reported for other protected lands. Using a management‐focused mercury impairment index, 80% of refuges contained sites classified as moderate or higher risk.

Contrasting effects of temperature across trophic levels in geothermally warmed soil food webs

open access: yesOikos, Volume 2026, Issue 5, May 2026.
Global warming is altering the structure and dynamics of ecological communities, with significant consequences for soil food webs. Rising temperatures are expected to accelerate metabolic rates in organisms, potentially altering species interactions, and the structure and energetics of food webs.

Rapidly declining seagrass meadows in Brazil: Findings from satellite imagery and local knowledge

open access: yesPeople and Nature, Volume 8, Issue 5, Page 1155-1171, May 2026.
Abstract Due to the limitations of individual monitoring approaches, integrating social perceptions with multiple advanced technologies provides a new opportunity to gain a comprehensive understanding of ecosystem degradation. We combined historical aerial mapping, satellite imagery, semi‐structured interviews with local stakeholders, and a bilingual ...

Stability in tapia woodlands amid non‐native expansion: Integrating traditional ecological knowledge and remote sensing to track 73 years of tree cover in Madagascar

open access: yesPeople and Nature, Volume 8, Issue 5, Page 1403-1418, May 2026.
Abstract Afromontane ecosystems, characterised by mosaics of fire‐adapted grassy ecosystems and fire‐sensitive forests, are biodiversity hotspots facing escalating pressures from non‐native species, climate and land‐use change. Madagascar's Central Highlands is one such hotspot, hosting woodlands dominated by endemic Uapaca bojeri (tapia) which are ...

Sharing the light, impact of solar parks on plant productivity, soil microbes and soil organic matter

open access: yesPLANTS, PEOPLE, PLANET, Volume 8, Issue 3, Page 1000-1013, May 2026.
Solar parks enable renewable energy production at a large scale, thereby reducing greenhouse gas emissions. However, the effects of this change in land use on vegetation and soil health are still largely unknown. In this study, we determined the impacts of solar parks on vegetation, soil biota and soil carbon between and below solar panels.
