Gray Fox

The Gray Fox, Urocyon cinereoargenteus, is listed federally as a threatened species in Canada, but has been undergoing a range expansion, with the first New Brunswick occurrence recorded in 2007. Here we document a second recent New Brunswick occurrence (2014) and suggest that monitoring the species in the province may be warranted.

First Occurrence

The first occurrence in New Brunswick of the Grey Fox (Urocyon cinereoargenteus), a threatened species in Canada, is documented based on a 4.3 kg subadult male trapped in the southwestern corner of the province. This is an approximate range extension of 135 km from the most northerly Maine occurrence and may reflect a larger North American range expansion underway since 1930-40, perhaps in response to warming climate.

One free-ranging Gray fox (Urocyon cinereoargenteus) underwent autopsy following neurologic disease, with findings including morbilliviral inclusions and associated lesions in numerous tissues, adenoviral intranuclear inclusions in bronchial epithelial cells, and septic pleuropneumonia, hepatitis, splenitis, and meningoencephalitis. Molecular diagnostics on fresh lung identified a strain within a distinct clade of canine distemper that is currently unique to wildlife in New England, as well as the emerging multi-host viral pathogen skunk adenovirus-1. Bacterial culture of fresh liver resulted in a pure growth of Listeria monocytogenes, with whole genome sequencing indicating that the isolate had a vast array of antimicrobial resistance and virulence-associated genes. One year later, a second fox was euthanized for inappropriate behavior in a residential area, and diagnostic workup revealed canine distemper and septic L. monocytogenes, with the former closely related to the distemper virus found in the previous fox and the latter divergent from the L. monocytogenes from the previous fox.

Gray Treefrog

Recent observations of the Gray Treefrog, Hyla versicolor, in the Maritimes suggest that this species may be expanding its range and abundance, perhaps partly in response to human activities. However, during the breeding season the species characteristically calls in very small choruses in the region and may be present but not call, or call for very short periods. This has made it difficult to determine distribution and to make an assessment of unconfirmed historic records that suggest presence beyond the current range more than 50 years ago. The inadvertent introduction of frogs may also be playing a role in the apparent recent range expansion of this species.
