Differential impact of marine debris ingestion during ontogenetic dietary shift of green turtles in Uruguayan waters

Anthropogenic debris ingestion has been reported for green turtles in all their life stages worldwide. The aim of the present study is to evaluate the marine debris ingestion by green turtles stranded in Uruguayan coast between 2005 and 2013. Debris items were categorized and quantified by frequency...
