Abstract:
... The absence of a rigorous mechanism for prioritizing investment in endangered species management is a major implementation hurdle affecting recovery. Here, we present a method for prioritizing strategies for endangered species management based on the likelihood of achieving species’ recovery goals per dollar invested. We demonstrate our approach for 15 species listed under Canada's Species at Risk ...

Abstract:
... We estimate the impact of removing an export subsidy on the local economies of Alberta, Saskatchewan and Manitoba, exploiting the large regional variation of a 1995 reform. We find that the loss of the subsidy resulted in significantly lower farm value‐added, farm asset values and local non‐farm employment. The results suggest that the subsidy removal had detrimental spillover effects on the local ...

Abstract:
... The water footprint (WF) of crop production is a user-friendly means to analyze the consumption of water resource in agricultural production systems. This study assessed the inter-annual variability of grain yield, protein yield, and their corresponding WFs and determined the major factors influencing the WFs in Saskatchewan of Canada. Both spring wheat and barley showed a significant trend of inc ...

Abstract:
... Legitimacy is typically given to an authority by a subject. In most cases, the state. However, different governance structures alter the role of the state and the support of some policy decisions rests on the actions of others. In mine development, government sits in an interesting position. As the permitting authority, government holds the responsibility for determining the paths companies must t ...

Abstract:
... Lease hunting, as a market-based policy instrument, can introduce monetary incentives to farmers to provide wildlife habitat. This article investigated farmer attitudes toward the introduction of a hypothetical lease hunting policy within a jurisdiction where there is significant demand for recreational hunting on private land but lease hunting is currently not legal. Farmers were evenly split bet ...

This study presents a multi-level nonlinear simulation-optimization (ML-NSO) model for groundwater remediation management when objectives should be satisfied at multiple levels. This model is formulated by integrating health-ri ...

While the upper Qu’Appelle is eutrophic, the middle Qu’Appelle River is hypereutrophic. To manage the river sustainably, there is a need to understand key processes governing eutrophication in both systems. In this study, a comprehensive global sensitivity ...

In this study, algae simulations were improved by implementing variable chlorophyll a/algal biomass ratios in the CE-QUAL-W2 model, a sophisticated two-dimensional laterally-averaged water quality model. Originally a constant in the model, the chl ...

Abstract:
... Stable isotopes have been used to quantify lake and wetland pond water loss to evaporation by applying the modified Craig and Gordon (1965) model. This model and its derivatives employ simplifying assumptions that ignore the additions of precipitation and infiltration outputs and assume evaporation is the only loss term over the prediction period. Here we develop a coupled water and isotope mass-b ...

Abstract:
... Streamflow response in Boreal Plains catchments depends on hydrological connectivity between forested uplands, lakes, and peatlands, and their hydrogeomorphic setting. Expected future drying of the Boreal Plains ecozone is expected to reduce hydrological connectivity of landscape units. To better understand run‐off generation during dry periods, we determined whether peatland and groundwater conne ...
