On behalf of my team, I am delighted to bring to your attention the publication of our last research published by the Journal of Environmental Monitoring and Assessment.

Bridge, C., Methion, S., & Díaz López, B. (2023). The impact of anthropogenic pollutants on the distribution of a marine top predator within a coastal estuarine system. Environmental Monitoring and Assessment, 195(7), 898.


Due to anthropogenic pressures, estuarine systems are among the most broadly impacted areas for marine top predator species. Given this, it is crucial to study the interaction between the vulnerable marine species that inhabit these regions
with environmental and anthropogenic variables. This study aims to determine whether nutrient pollution is related to the presence of bottlenose dolphins in a coastal environment. Using a multi-year dataset and GAMs, we studied the relationship
between marine pollutants and the presence of bottlenose dolphins in this highly impacted coastal marine environment. We observed that urban fertilizers were linked to the spatial distribution of bottlenose dolphins. There was a higher presence
of bottlenose dolphins in areas with high levels of phosphoric acid. In contrast, at higher concentrations of nitrate, the presence of bottlenose dolphins decreased.
