Gilhen, John, Alice Jones, Jeffie McNeil, and Arthur W. Tanner. 2012. A significant range extension for the Eastern Ribbonsnake, Thamnophis sauritus, in Nova Scotia, Canada. Canadian Field-Naturalist 126(3): 231-233.
Abstract / Description:
In Nova Scotia the threatened Northern Ribbonsnake, Thamnophis sauritus septentrionalis, (the northern subspecies of the Eastern Ribbonsnake, T. sauritus) (Crother 2008) is known from localities in only Queens and Lunenburg counties, where it was first discovered in 1950. Many new localities, mostly in the headwaters of the Mersey River and the Medway River

Abstract / Description:
We present evidence that eastern ribbon snakes (Thamnophis sauritus) at low environmental temperatures can maintain significant temperature differentials between their bodies and tails. We used a high resolution infrared camera to record thermal data from ribbon snakes in the spring and summer. An independent two sample t -test confirmed that ribbon snakes at low spring environmental temp   click for more

Todd, J. and R. Wassersug. 2010. Caudal pseudoautotomy in the Eastern Ribbon Snake,Thamnophis sauritus. Amphibia-Reptilia 31 (2010): 213-215.
Abstract / Description:
Frequent tail loss has been reported in a variety of reptiles including sphenodonts, lizards, amphisbaenids, and snakes. We report evidence of non-specialized pseudoautotomy as an antipredator defense in the Eastern Ribbon Snake Thamnophis sauritus. In field studies in Nova Scotia, Canada, T. sauritus were frequently found with partial tails, during three capture attempts T.   click for more

Imlay, T. 2009. Examining spatial ecology at multiple scales: implications for eastern ribbonsnake (Thamnophis sauritus) recovery in Nova Scotia. MSc thesis. Acadia University. Wolfville, NS.
Abstract / Description:
The Eastern ribbonsnake (Thamnophis sauritus) is a threatened species in Nova Scotia. Many threats and limiting factors have been identified for the species, however the lack of knowledge surrounding movement patterns and habitat use inhibit recovery decisions. Ribbonsnakes were hand-caught during visual surveys at Grafton and Molega Lakes in 2007. Two methods for tracking ribbonsnakes we   click for more

Saroli, J. 2009. Habitat use and movement of the Eastern ribbonsnake (Thamnophis sauritus) at meso-scales.BScH thesis, Acadia University, Wolfville, NS.
Abstract / Description:
The Eastern Ribbonsnake (Thamnophis sauritus) is listed as a threatened species in Nova Scotia. The threat of diminishing habitat due to shoreline property development combined with a general dearth of knowledge on the snakes' movements and habitat use complicates conservation and potential recovery planning. Visual surveys were conducted at Molega Lake, an area known to contain a small p   click for more

Abstract / Description:
We investigated whether Eastern Ribbon Snakes (Thamnophis sauritus (L., 1766)) use a rise in water level as a cue for emergence from hibernation. We also examined the hypotheses that snakes use temperature gradients or endogenous signals as emergence cues. Twelve artificial hibernacula were used to house 15 Ribbon Snakes. Water level and temperature were regulated. Four Ribbon Snakes emer   click for more

McLaughlin, C. 2008. Microsatellite analysis of population structure in the eastern ribbonsnake,Thamnophis sauritus. BScH thesis. Acadia University. Wolfville, NS.
Abstract / Description:
The Eastern Ribbonsnake, Thamnophis sauritus, exists in Nova Scotia as a disjunct population in the Southwest region of the province. This small population, estimated at 1000-3000 individuals, is particularly vulnerable to change due to its isolation and, therefore, was classified as ‘threatened’ in 2002 by COSEWIC. Because very little is known about the behaviour, ecology, and genetic st   click for more

Todd, J. 2007. Ecology of the Eastern Ribbonsnake (Thamnophis sauritus) in a disjunct population in southwest Nova Scotia. MSc thesis. Dalhousie University, Halifax, NS.
Abstract / Description:
In Nova Scotia the Eastern ribbonsnake Thamnophis sauritus is considered threatened under the Canadian Species at Risk Act because it is disjunct from the rest of the species range and populations in the region are believed to be small. There is a paucity of data on T. sauritus in Nova Scotia; this is a barrier to its recovery. A free-ranging population of T. sauritus in   click for more
