The Zooplankton of Tanquary Fjord, Ellesmere Island, with Special Reference to Calanoid Copepods
Tanquary Fjord is ice-covered for a large part of the summer and hence very unproductive. The zooplankton showed variation between the years 1963 and 1964 both in abundance and in species composition, suggesting an unstable system. Development rates and breeding cycles of the calanoid copepods were...
