Multispecies Niche Overlap: Moving Beyond Pairwise Metrics to Understand Community‐Wide Similarities in Resource Use

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Measures of niche overlap are important tools in various ecological and evolutionary studies. Here we create and apply a multispecies overlap metric to both simulated and empirical communities, illustrating how this methodology may capture interactions and structure of niche space in ways that traditional, pairwise metrics overlook.

The paradox of mosquito net fishing: Complex socio‐ecological trade‐offs in southwestern Madagascar

People and Nature, Volume 8, Issue 6, Page 1755-1772, June 2026.
Abstract Small‐scale fisheries are vital for the livelihoods, nutrition and well‐being of millions of people in coastal regions. In many parts of the Global South, rising poverty, limited alternatives and declining resources have driven the spread of mosquito net fishing (MNF), a non‐selective practice using repurposed health‐distributed nets.

Diazotrophic Cyanobacteria are Associated With a Low Nitrate Resupply to Surface Waters in Lake Tanganyika

Frontiers in Environmental Science, 2021
In Lake Tanganyika, blooms of nitrogen-fixing (diazotrophic) cyanobacteria emerge, when the upper water column re-stratifies after a period of upwelling and convective mixing.
