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

open access: yesLimnology and Oceanography: Methods, EarlyView.
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.

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

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
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.
