We examined a unique time series of ringed seal (Phoca hispida) samples collected from single location in the western Canadian Arctic between 1973 and 2007 to test for changes total mercury (THg) muscle tissue associated with (1) year (2) length ice-free season. found no temporal trend THg whereas curvilinear relationship existed season: seals attained higher short (2 months) long (5 seasons. δ15N δ13C did not illustrate significant trends days. estimated that turnover was about twice as...
The association between changing sea ice conditions and contaminant exposure to Arctic animals interests Inuvialuit harvesters, communities, researchers. We examined organochlorine (OC) concentrations in the blubber of 90 male adult ringed seals (Phoca hispida) sampled from subsistence harvest Ulukhaktok (formerly Holman), NT, Canada, just prior break-up (1993-2008). OC were assessed with respect year date. HCB age- blubber-adjusted p,p'-DDT ΣCHB (chlorobornane) significantly decreased over...
Abstract Since 1968, the Australian Dung Beetle Project has carried out field releases of 43 deliberately introduced dung beetle species for biological control livestock and dung‐breeding pests. Of these, 23 are known to have become established. For most these species, sufficient time elapsed population expansion fill extent their potential geographic range through both natural human‐assisted dispersal. Consequently, over last 20 years, extensive efforts been made quantify current...
It is the right of Canadian Inuit to hunt marine mammals for subsistence. Most this food consumed raw, yet it under goes no formal government inspection or certification. Hunters also encounter sick abnormal animals and they are becoming increasingly concerned about wholesomeness that eat. They epizootics may severely limit number available their use. As a result, Department Fisheries Oceans Canada (DFO) has been asked by wildlife management groups determine what possible disease threats...
