Marine Ecology, EarlyView., 2023 Abstract Plankton play a key role in marine food webs by producing and transferring organic matter and energy to higher trophic levels. To define the trophic structure and interactions within the planktonic communities in the Gulf of Naples, we determined carbon and nitrogen stable isotope ratios in particulate organic matter (POM, <20 μm ...

People and Nature, EarlyView.Abstract Although there have been several initiatives to establish and support participatory processes on large carnivores based on multi‐stakeholder governance at the regional level in Europe, empirical evidence for their evaluation is still lacking. We employed a survey, which was administered to farmers and other stakeholder groups (e.g.

The paradox of mosquito net fishing: Complex socio‐ecological trade‐offs in southwestern Madagascar
People and Nature, EarlyView.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.

Biplots of fuzzy coded data [PDF]
A biplot, which is the multivariate generalization of the two-variable scatterplot, can be used to visualize the results of many multivariate techniques, especially those that are based on the singular value decomposition.
