- Abstract:
- Regime shifts of food webs are governed not only by climatic changes, but also by biological factors such as prey switching or competitive exclusion. Observed decreases in krill in the Southern Ocean have severe implications for the fisheries they support. However, lack of knowledge of their biology, including feeding, limits our predictions of how they will respond to future change. Krill are generally thought to be mainly herbivorous, but recent data and models suggest the importance of omnivory. We hypothesise that, outside of bloom periods, they not only predate copepods but do so at physiologically meaningful rates, allowing positive growth to be maintained during non-bloom conditions. We will use 4 independent methods to measure krill diet, and use the results in models that explore the extent to which omnivory buffers phytoplankton shortage for larval, juvenile and adult krill.
