Reproduction and Mortality of the High Arctic Wolf, Canis lupus arctos, in Northeast Greenland, 1978-1998
Reproduction and mortality of the High Arctic Wolf (Canis lupus arctos) in northeast Greenland were investigated through a temporal and spatial analysis of data on litter sizes from direct counts of pups during 21 years (1978-1998). A minimum of 22 pups were produced in a total of six areas. Overall...
