Integrating dedicated and opportunistic surveys to estimate seasonal common dolphin density off mainland Portugal

This paper develops a spatiotemporal model to integrate dedicated and opportunistic surveys for estimating seasonal common dolphin density off Portugal, providing animal-level density estimates with uncertainty.

Exploring the relationship between dolphins and fisheries: uncovering the spatial and temporal patterns that influence potential conflicts along Portugal's north coast

This study maps spatial and temporal overlaps between common dolphin sightings and fishing activity along Portugal's north coast using AIS data and environmental variables.

Assessing fish welfare in small-scale commercial fixed-net fisheries off the southern Portuguese coast

This study assesses fish welfare in small-scale fixed-net fisheries by evaluating behavioural and physiological indicators across four species.

Seasonal and interannual variation of common dolphin densities in Portuguese waters

This study models common dolphin densities in Portuguese waters using environmental factors, showing seasonal patterns and interannual variation linked to sardine biomass and oceanographic conditions.
