Population dynamics of Antarctic krill Euphausia superba at South Georgia: sampling with predators provides new insights / K. Reid, and 3 others.

Title: Population dynamics of Antarctic krill Euphausia superba at South Georgia: sampling with predators provides new insights / K. Reid, and 3 others.
Author(s): Reid, K.
Date: 2006.
Publisher: Cambridge: Cambridge University Press
In: Top predators in marine ecosystems : their role in monitoring and management. (2006.),
Abstract: Describes programme to determine changes in krill population dynamics associated with changes in abundance, using size composition of krill in diet of Antarctic fur seals breeding at South Georgia. Long-term monitoring of land-based marine predators over past 20 years has shown changes in relationship between krill population structure and abundance and reproductive performance of range of predators with very different life-history strategies and ecologies. Increase in frequency of years with insufficient krill to support predator demand indicates ecosystem-wide response and suggests fundamental change in availability of krill over large scale. Relationships between recruitment patterns of krill and environmental-temperature indices may be relevant, given increasing evidence for long-term reduction in extent and duration of sea ice and increase in winter air temperatures in Antarctic Peninsula region.
