Fish and Fisheries, Volume 26, Issue 3, Page 372-393, May 2025.
ABSTRACT Scientific advice for fisheries management rarely takes into account how fishers react to regulations, which can lead to unexpected results and unrealistic expectations of the effectiveness of the management measures. Short‐term decisions about when and where to fish are one of the greatest sources of uncertainty in predicting management ...

Accurate estimation of photosynthetic available radiation from multispectral downwelling irradiance profiles

Limnology and Oceanography: Methods, Volume 23, Issue 4, Page 261-272, April 2025.
Abstract Photosynthetic available radiation (PAR) is the light usable by photosynthetic organisms. Photosynthetic available radiation measurements at depth are required to quantify the light availability for primary production. Direct PAR measurements may be measured with full‐spectrum quantum sensors for the range 400 to 700 nm.

Light competition affects how tree growth and survival respond to climate

Journal of Ecology, Volume 113, Issue 3, Page 672-688, March 2025.
We analysed the effect of light competition on tree growth and survival along both temperature and aridity gradients for the 33 major European tree species. We used forest data from nine European countries and the SamsaraLight ray tracing model. We found that the effect of light competition is weaker in stressful environments.

Emergent Relationships Between the Functional Diversity of Marine Planktonic Copepods and Ecosystem Functioning in the Global Ocean

Global Change Biology, Volume 31, Issue 3, March 2025.
We evaluate how the diversity and functional traits of copepods—tiny crustaceans that constitute the majority of marine zooplankton—relate to key processes in the oceans such as the production of plankton biomass and how it sinks at depth. The study found that a few dominant copepod species disproportionately shape these processes.
