Gillnet modifications to reduce bycatch of harbor porpoises
, 2021 Gillnets are passive fishing gears that belong to the oldest and most frequently used gears worldwide, providing income and food for millions of people. They are most used in small-scale and artisanal coastal fisheries and operated from small boats often less than 12 m in length.

Evolution of group size in the dolphins and porpoises: interspecific consistency of intraspecific patterns [PDF]
, 2017 I investigated group size variability in dolphins and porpoises using intraspecific comparisons. Explanatory factors considered in the analysis were variables of the physical environment, the diet, and the life history of the species.
