Size and Seasonal Fluctuations of an Extra-limital Population of Black-tailed Prairie Dogs, Cynomys ludovicianus, in Central Alberta

Posted on May 31, 2019

Author by Gilbert PROULX CWBM 8 (1): 1–8 Abstract The black-tailed prairie dog (Cynomys ludovicianus) is a Threatened Species with a Canadian distribution limited to southwestern Saskatchewan, in and around Grasslands National Park. If populations were to be decimated or depleted, e.g., by drought or sylvatic plague, an extra-limital black-tailed prairie dog colony in central Alberta could be a source of animals for translocations. This study investigated the size and the fluctuations of this black-tailed prairie dog population from 2013 to 2017, with surveys conducted in early and late...

Comparison of Beaver Density Estimates from Aerial Surveys of Waterways Versus Transects

Posted on May 31, 2019

Author by Shannon BARBER-MEYER CWBM 8 (1): 9–16 Correspondence: U. S. Geological Survey, 1393 Hwy 169, Ely, Minnesota, USA 55731. Email: sbarber-meyer@usgs.gov Abstract Historic beaver-sign (Castor canadensis) survey flights were often conducted over waterways to maximize beaver detections. However, densities determined from strip transect surveys are more useful to compare across and within study areas than waterway indices based on observations per distance flown because transects are more representative of the wider landscape. Yet, it is unknown if, and to what extent, aerial waterway...

Web-GIS, Citizen Science, and Human-Coyote Encounters in Calgary, Alberta (2010-2012)

Posted on May 31, 2019

Author by Meghan S.C. RYCHYK and Shelley M. ALEXANDER CWBM 8 (1): 17–35 Correspondence: University of Calgary, 2500 University Drive NW, ES 118, Earth Sciences Building, Calgary, Alberta, T2N 1N4, Canada. Email: m.rychyk@ucalgary.ca Abstract Urban coyotes (Canis latrans) live in habitat remnants, often supplementing natural food sources with anthropogenic alternatives that bring them into close contact with humans. We analyzed 781 citizen reports submitted to the web-GIS mapping tool, Living with Coyotes, between 2010 and 2012, in Calgary, Alberta. Encounters were classified into 5 types and...

Monthly Variation in Scat Marking by River Otters along Tionesta Creek in Northwestern Pennsylvania

Posted on May 31, 2019

Author by Thomas L. SERFASS, Colin P. CARPENTER, and Maggie D. TRISKA CWBM 8 (1): 36–44 Correspondence: Thomas L. Serfass, Department of Biology and Natural Resources, Frostburg State University, Frostburg, Maryland 21532, USA. Email: tserfass@frostburg.edu Abstract We examined monthly variation in scat marking by river otters (Lontra canadensis) by surveying both shorelines of a 17.3 km section of Tionesta Creek in northwestern Pennsylvania once a month from 4 March 2000 to 24 March 2001 to count the number of scats and latrines (sites where river otters deposit scats). Overall, we counted...

Can You Tell the Turtle by its Eggshell?

Posted on Nov 9, 2018

Author by Siow Yan Jennifer ANGOH, Lauren A. HOOTON, and Christina DAVY CWBM 7 (2): 90-95 Correspondence: Christina Davy, Ontario Ministry of Natural Resources and Forestry, Wildlife Research and Monitoring Section, Trent University, Peterborough, Ontario, K9J 7B8, Canada. Email: christina.davy@ontario.ca Abstract Species at risk in Canada receive different levels of habitat protection depending on their status under the federal Species at Risk Act (e.g., Endangered or Threatened, vs. Special Concern). Accurate detection of species presence can facilitate appropriate habitat protection. For...
