Advancing the mapping of vegetation structure in savannas using Sentinel‐1 imagery
As vegetation structure monitoring is important for the understanding and conservation of savanna ecosystems, we explored the utility of C-band synthetic aperture radar imagery for mapping both grass...

Experimental evidence of the role of nitrogen for eutrophication in shallow lakes: A long-term climate effect mesocosm study
The effectiveness of controlling nitrogen (N) loading (in addition to phosphorus [P]) to manage the eutrophication of aquatic ecosystems has been debated despite the role of N in producing algal biomass and toxins. Long-term, controlled tests of the efficacy of N loading reductions are largely missing from the scientific record, perhaps due to the historical focus on P control. To address this knowledge gap, we examined the results from a unique, long-term study conducted in 24 flow-through (2.5-month retention time) lake ecosystem-scale mesocosms in Denmark, operating since 2003 at two contrasting nutrient loading levels crossed with three temperature scenarios (ambient, IPCC (Intergovernmental Panel on Climate Change) A2 scenario, and A2+50%).
