Can we detect fast growth responses in slow environments?
The main influence on the growth rates of Antarctic benthic invertebrates is food availability. The benthic fauna rely heavily on the seasonal influx of organic material derived from the annual phytoplankton bloom in late spring-early summer. Thus, even though the average annual growth rate can be extremely low, the growth rate of benthic fauna is expected to increase significantly when food is abundant. This project aimed to test the responses of benthic fauna to fluctuations in food availability at sample sites around McMurdo Sound.
