Multiple approaches to meso- and macroplastics and the food habitat of the green turtle, <i>Chelonia mydas</i>, in the Ogasawara Islands, Japan.

ABSTRACT: This study integrated genetic, isotopic, and plastic analyses to investigate the diet and plastic ingestion of adult green turtles living in the waters around the Ogasawara Islands. Micro-, meso-, and macroplastics were found in the gut contents of 7 of the 10 individuals examined. A total of 92 meso- and macroplastics were found in six individuals, with an average of 9.2 ± 11.48 items/individual (range: 0-31, n = 10). The average total weight of these items was 15.28 ± 24.76 g (range: 0-70.55, n = 10), and their average percentage of the turtles' body weight was 0.014 ± 0.021% (range: 0-0.064, n = 8). At the time of capture, the turtles' main food was macroalgae, and the feeding grounds were estimated from the DNA analysis to be three locations where the seaweeds E
