Cast away: Tracing the voyage of a plastic bottle cap and its hitchhiking marine species

Researchers have traced the journey of a plastic bottle cap recovered near the waters of southern Japan by combining data from the label, chemical clues in tiny shells and ocean current simulations. They found 307 organisms, including a polychaete worm not found in Japanese waters before. The findings, published in Marine Pollution Bulletin, show that when species that significantly shape their environments (ecosystem engineers) colonize plastic debris, entire micro-communities can be transported over extended periods, with implications for invasive species risk and marine biodiversity conservation.
