United States and Canadian governments have responded to legal requirements to reduce human-induced whale mortality via vessel strikes and entanglement in fishing gear by implementing a suite of regulatory actions. We analyzed the spatial and temporal patterns of mortality of large whales in the Nor...

A small commercial hunt for 5-7 weeks old grey seals (Halichoerus grypus) occurs intermittently around the Canadian Maritime provinces and may expand in the near future. We sought to better understand and, where possible, improve the harvesting methods of this hunt. We compared the use of the regula...

Cloacal and pharyngeal swabs from 100 tree-nesting Double-crested cormorant (DCC) chicks were examined by culture for commensal and potentially pathogenic bacteria. No Salmonella or Erysipelothrix were isolated from the cloacal swabs. Twenty-two cloacal swabs were positive for Campylobacter, of whic...

In fall 1991, a radio-collared black bear (Ursus americanus) in northern Labrador (Canada) died from valvular endocarditis caused by coagulase-positive Staphylococcus aureus, with widespread dissemination of the infection to other organs shortly before death. Apparently, this is the first reported c...

Specimens of Bolbosoma capitatum and Bolbosoma sp. were recovered from 2 male Physeter macrocephalus that died following a mass stranding on Prince Edward Island, Canada. Some aspects of previous descriptions of B. capitatum have been incomplete, particularly with characteristics of the hooks of the...

Between 1993 and 1999, encephalitis caused by morbillivirus was diagnosed by immunohistochemistry and histology in six lynx (Lynx canadensis) and one bobcat (Lynx rufus) in the eastern Canadian provinces of New Brunswick and Nova Scotia. Five of the six cases in lynx occurred within an 11-mo period ...

Between 15 November and 13 December 1993, three cases of rabies of probable bat origin were confirmed in red foxes (Vulpes vulpes) from the same area of Prince Edward Island, Canada, previously thought to be free of rabies in terrestrial mammals. Such clusters have rarely been described in North Ame...

Hot branding has been used for many years by researchers to identify seals from a long distance. In livestock, cold branding has been proposed as an alternative because it is thought to be less painful. The purpose of this study was to compare the healing process of hot and cold brands applied to ha...

Double-crested Cormorants (Phalacrocorax auritus) breeding at a Prince Edward Island colony, the largest in northeastern North America, shifted their nesting location to a nearby island after springtime shooting at the colony. Post-shift numbers at the new site (4525 nests) were 92% of the previous ...

We describe 4 years of an experimental rotation in ecosystem health offered to senior veterinary students in Canada. Faculty from the 4 Canadian veterinary colleges collaborated in offering the rotation once annually at 1 of the colleges. The 1st rotation was held in Guelph in 1993, followed in succ...
