Mothbox and Mothbot: Automated light trap and data processing system for scalable insect monitoring

Methods in Ecology and Evolution, Volume 17, Issue 7, Page 2082-2091, July 2026.
Abstract Insects represent the most diverse group of organisms on Earth and comprise the majority of known species; yet they are seldom accounted for in large‐scale biodiversity monitoring systems and conservation planning. We have developed the Mothbox—an open source automated light trap that makes insect monitoring accessible to non‐specialists and ...

Applicability of the steady‐state oxygen stable isotope method for estimating metabolism in low‐productivity Arctic lakes

Limnology and Oceanography: Methods, Volume 24, Issue 6, June 2026.
Abstract Metabolism is a key property of lake ecosystem functioning, but logistical challenges make it difficult to estimate across remote regions. The steady‐state dissolved oxygen (DO) stable isotope method (18O method) estimates metabolism from discrete water samples and thus enables large‐scale surveys.

Charge towards green finance ignores risks of nature commodification: Evidence from the UK's climate and nature recovery policy landscape

People and Nature, Volume 8, Issue 5, Page 1297-1308, May 2026.
Abstract The urgent need for up‐scaled finance has become central to the climate and nature recovery discourses worldwide. With most existing investments coming from public sources, closing the financing gap has become the overpowering argument for calling for private investments into nature restoration and conservation.

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

PLANTS, 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.

Fresh Phytoplankton Bloom Growth in the Fall and Its Control on Ocean Heating in the Pacific Arctic Region

Journal of Geophysical Research: Oceans, Volume 131, Issue 5, May 2026.
Abstract Delayed sea ice freeze‐up and decreased sea ice extent in the Pacific Arctic region have altered light availability in marine waters, extending the ice‐free season and increasing opportunities for photosynthetic activity and energy exchanges. This study investigates phytoplankton bloom progression during the fall using chlorophyll pigments and
