Population dynamics of Weddell seals (Leptonychotes weddelli) in McMurdo Sound and the Victoria Land Coast: movement in the area, sub-adult populations, age structure and reproductive condition
Entry ID: K017_1960_1973_NZ_1

Abstract: The population parameters of the Weddell seal in McMurdo Sound was initiated in the 1965-66 season following a 4 year study of the reproductive cycle of the Weddell seal and 2 years of tagging by the USARP. Secondary objectives of the study include assessment of the effects of fluctuations of environmental conditions upon daily activities and the onset of pupping and to study the behaviour of the ...

Quality The majority of the results of surveys, numbers, demographic values, ecology, and so on has been published in the references list. The investigator still holds tabulations of numbers of pups at different breeding colonies and various other values, necropsy forms completed in the early 60s from seals killed for dog food at Scott Base and some Weddell seal canine teeth, collected in the late 60s, that were used for age determination and, much later, some genetic work, listed in the publications. Please contact the investigator for more information.
