| The aim of this study was to test the effect of food quantity on energy storage and defense capacities of oysters during a reproductive cycle. One-year-old Crassostrea gigas oysters were fed two different dietary rations (4% and 12% of oyster dry weight in algal dry weight per day) in controlled experimental conditions over an annual cycle. Oyster dry weights, carbohydrate and lipid contents, energetic adenylate charge, and hemocyte parameters of oysters were significantly affected by reproductive processes related to seasonal temperature variation and, to a lesser extent, by the dietary rations. Energy parameters decreased during gametogenesis as gonads developed then increased during the gonad resorption phase. The additional energy provided to oysters... |

| A linear programming model is used to examine the impact of carbon taxes on the optimal generation mix in the Alberta electrical system. The model permits decommissioning of generating assets with high carbon dioxide emissions and investment in new gas-fired, wind and, in some scenarios, nuclear capacity. Although there is an intertie from Alberta to the U.S., the focus is on the connection to British Columbia as wind energy can potentially be stored in reservoirs behind hydroelectric dams. However, storage can also be used to smooth out the net load facing nuclear facilities. A carbon tax facilitates early removal of coal-fired capacity, which is replaced by low-emissions gas plants. It is only when the carbon tax exceeds $125/tCO2 that wind enters the... |
