Abstract Sciurus carolinensis (Eastern Gray Squirrel) is one of the most recognized sciurids in North America. Since 1930, apparently isolated Nova Scotia sightings of Eastern Gray Squirrel have been believed to result from captive releases or escapes. However, the species was not believed to have become established in the province. Here we report first evidence that the Eastern Gray Squirrel is now present as a breeding mammal in Nova Scotia. 

Records of Melanistic American Red Squirrels ( Tamiasciurus hudsonicus ) from Nova Scotia

This work provides the first detailed accounts of melanistic Red Squirrels observed in Nova Scotia, Canada, and reports the occurrence of this phenotype for the first time.

Non-native small mammal species in the South African pet trade

Non-native small mammals are amongst the most popular species traded as pets around the world. Some of these mammals have become invasive through various pet trade releases and escapees in most

Assessing the potential impacts of non-native small mammals in the South African pet trade

The Generic Impact Scoring System was used to assess the potential effects associated with 24 non-native small mammal species sold in the South African pet trade and found no statistically significant difference between the overall environmental and socio-economic impact scores.

Predicting the Potential Distribution of Non-Native Mammalian Species Sold in the South African Pet Trade

The results provide a baseline approach that can be used to identify mammalian pet species with a potential risk of invasion so that urgent preventive measures can be implemented and suggest the need of strict trade regulations and management strategies for pet mammals with broader suitability.



The Land Mammals of Nova Scotia

The first comprehensive accounts of the mammals of Nova Scotia were by J. Bernard Gilpin whose findings were published in the period 1867 to 1874. Indeed, up until now no one else seems to have

Canada Lynx, Lynx canadensis , Use of the Chignecto Isthmus and the Possibility of Gene Flow between Populations in New Brunswick and Nova Scotia

An observation of tracks made by Canada Lynx on the Chignecto Isthmus supports assumed use of this area between New Brunswick and Nova Scotia as a potential wildlife corridor. Use of the isthmus by

Bark‐stripping by Grey squirrels (Sciurus carolinensis)

The results indicate that bark-stripping can be initiated by young squirrels, perhaps through agonistic gnawing or exploratory feeding, or by older squirrels which have learned the habit, but that severe damage occurs only where the tree phloem is suitable.


The latest taxonomic, distributional, habitat and conservation status information is presented for a total of 91 species of marine and terrestrial mammals presently or historically known from Nova

Positive relationship between non-native and native squirrels in an urban landscape

There was no evidence that non-native squirrels replaced native squirrels given that their abundances were positively related, whereas native Squirrels varied negatively with the amount of development.

Guidelines of the American Society of Mammalogists for the Use of Wild Mammals in Research

General guidelines for use of wild mammal species are updated from the 1998 version approved by the ASM and expanded to include additional resources to include details on marking, housing, trapping, and collecting mammals.

The more you introduce the more you get: the role of colonization pressure and propagule pressure in invasion ecology

It is argued that ‘propagule pressure’, a key term in invasion biology, has been attributed at least three distinct definitions, with the result that the distinct importance of these different concepts has been at best diluted, and at worst lost.
