The effect of economic inequality on voter turnout in Canadian federal elections, 1979-2011

Since the 1990s, voter turnout in Canadian federal elections has decreased considerably. During the same period, economic inequality significantly increased. Although there is much theoretical work, there have been few empirical studies examining the effect of economic inequality on voter turnout. Using data collected from both national and international sources, I conducted an aggregate level, time series analysis of national turnout and economic inequality for Canadian federal elections between 1979 and 2011. Moreover, this thesis tests Schattschneider's (1960) hypothesis, which argues that increasing rates of voter abstention are a result of economic inequality magnifying differences in relative power between affluent and non-affluent citizens. The findings indicate that economic inequality has a strong negative effect on voter turnout.

Effects of introduced moose (Alces alces) on vegetation composition, nutrient dynamics, and decomposition rates in boreal forest ecosystems in Newfoundland, Canada

Globally, consumers affect ecosystem processes including nutrient dynamics. Herbivores have been known to slow nutrient flow in boreal forest ecosystems. I examined the effects of introduced moose on disturbed forests of Newfoundland, Canada by conducting a field experiment during August - November 2014 in 20 paired moose exclosure-control plots. I tested whether moose browsing directly and indirectly affected forests by measuring plant species composition, litter quality and quantity, soil quality, and decomposition rates in areas moose exclosure-control plots. I analyzed moose effects using linear mixed effects models and found evidence indicating that moose reduce plant height and litter biomass affecting the availability of carbon, nitrogen, and phosphorus. However, plant diversity, soil quality, and litter decomposition did not differ between moose exclosures and controls. Moose in Newfoundland directly influence plant regeneration and litter biomass while indirect effects on soil ecosystems may be limited by time, disturbance, and climate.
