摘要:
Australian sea lions consume prey in highly productive foraging grounds and defaecate nutrients on land. The resident population of 1100 Australian sea lions contributes 3800 (+/- 80) kg N year(-1) into Seal Bay Conservation Park, Kangaroo Island, South Australia. If this population were to decline in abundance the nitrogen availability and coastal productivity of Kangaroo Island may be reduced.
