Abstract

One of the multiple consequences of global warming is the loss of sea ice cover of the Arctic and warming up of its surface waters. It is predicted that in 35 years the Arctic will be ice free in summer. It has to be considered that these changes in the environment will have irreversible consequences for marine ecosystems. Some of the consequences that are being most considered are the increase in primary productivity and the potential mismatch between the primary and secondary production. In this review I have studied the phenology and life cycle of two species of common Arctic copepods of the genus Calanus (C. gracialis and C. marshallae) along the Bering, Chukchi and Beaufort seas in the context of the above mentioned aspects of climate. I concluded that the most likely scenario is that primary productivity will increase and, with the exception of the Bering Sea, secondary productivity will increase as well. In addition, the successful colonization of C. marshallae in the Arctic Ocean likely results from the increase in primary productivity, temperature and longer growing season.
