Master of Science in Ecological Restoration Applied Research Projects
Description
This is Canada’s first master’s program specializing in Ecological Restoration and is offered as a joint program between British Columbia Institute of Technology (BCIT) and Simon Fraser University (SFU). The MSc in Ecological Restoration combines the strong technical and applied (experiential) knowledge at BCIT with SFU’s fundamental (contextual) basic science and community engagement expertise.
Prairie dogs (Cynomys ludovicianus) are considered a keystone species due to their ecological role in maintaining the prairies. In Canada, they are federally listed as a threatened species. This study was conducted to identify the limiting factors to the expansion of prairie dog colonies in Grasslands National Park, Saskatchewan. I tested different hypotheses to compare landforms, vegetation, and soil characteristics in three treatments: consistently occupied (Consistent), inconsistently occupied (Inconsistent), and never occupied (Buffer) by prairie dogs. I sampled four prairie dog colonies (blocks) from 17 July 2019 to 28 August 2019 using a randomized complete block design. I used ANOVA to test variables for significant differences among treatments. My results showed that hills, water channel, shrublands, grass cover, shrub cover and vegetation height classes (>30 cm) were significantly higher (p <0.05) in Buffer compared to Consistent and Inconsistent. Shrubs and tall vegetation should be mowed down to enhance the expansion of prairie dog colonies for restoring their population., restoration, prairie dogs, Cynomys ludovicianus, colony expansion, barriers, habitat use
Relationships between changing environmental variables and amphibian populations have been understudied. Yet, alterations to temperature and precipitation have been suggested as contributors to the decline of some pond-breeding species, such as the Oregon Spotted Frog (Rana pretiosa). R. pretiosa has been classified as the most endangered amphibian in Canada, yet the cause for its decline is unknown. Therefore, this paper examined associations between temperature and precipitation, and R. pretiosa population trends, using a 10-year data set from two breeding populations in the
Lower Mainland of British Columbia. Timing of oviposition was positively related to higher temperature and increased precipitation within both populations (p<0.05). No statistical relationship was determined between egg mass productivity and temperature or precipitation; however, this paper proposes that further research, consistent protocols and longer study periods, is necessary in order to determine environmental variables as possible predictors of population success. This paper recommends the evaluation of breeding success through survivorship studies, as such methods provide insight into
productivity as the primary determinant for population recruitment. Further, ecological restoration efforts can be implemented to help ameliorate negative consequences climate change poses on reproductive success., amphibian, climate change, conservation, ecological restoration, endangered, population dynamics, population monitoring, survivorship
