Increased incidence of entanglements and ingested marine debris in Dutch seals from 2010 to 2020
In recent decades, the amount of marine debris has increased in our oceans. As wildlife interactions with debris increase, so does the number of entangled animals, impairing normal behavior and potentially affecting the survival of these individuals. The current study summarizes data on two phocid s...
