  Citation × Citation Citation Abstract Copy Title: Identifying a Ranking of Plant Preferences for a Pollinator Author: Krishna Kumaran, Sneha Pollinators are an integral part of agriculture and the ecosystem. However, due to changing land use, populations of wild pollinators are decreasing and plant distributions are changing all around the world. To understand how plant-pollinator networks will adapt over time, we would like to understand how pollinators choose flowers to visit. We will model a pollinator’s interaction with plant species in two ways: first using a probabilistic multinomial approach to fit a preference score to each plant and second to explain our findings from the multinomial model using the traits of the flowers themselves. Our findings show that a model with preferences performs better than a model which does not have preferences. While this model shows potential in finding plant preferences, it does not fully explain the distribution of plant-pollinator interactions. To try to explain the interactions more fully, we incorporated the traits of the plants into the score of the plant. We found that the traits do have some effect on the score of the plant, but again do not fully explain the interactions in this particular model.

  Citation × Citation Citation Abstract Copy Title: Opportunity costs : irrigation vs. hydropower Author: Ross, Mark In recent years we have seen increasing debate over the allocation of PNW water resources. In particular there are conflicts over using the river system for irrigation vs. electricity production. Denying the hydroelectric system water implies higher costs to electricity consumers as producers substitute more expensive nonhydro resources. This research looked at the impact of new irrigation on PNW electricity consumers. This was done under varying assumptions of demand response and farmer payments for pumping of irrigation water. The study also examined the difference between the current policy of allowing farmers to take all the water they need, and a policy in which withdrawals are limited in periods of low streamflow. Simulations were run to determine the amount of electricity production lost because of withdrawals. These results were then used in a series of simulations to estimate the economic impacts under the various assumptions and policies. It was found that irrigation caused losses to electricity consumers. In some cases this loss was on the order of $200/acre of irrigated land. The loss was significantly mitigated under the interruptible policy. Farmer payments for irrigation energy also reduced the loss to consumers.

• 1630. [Article] On Demand-side Approaches to Solving the "Tragedy of High Prices" in Fisheries

  Citation × Citation Citation Abstract Copy Title: On Demand-side Approaches to Solving the "Tragedy of High Prices" in Fisheries Author: Valatin, Gregory Year: 2001 While overfishing frequently is explained in terms of «the Tragedy of the Commons» model, it is argued that the economic causes of such long-run resource problems could be more accurately characterised in terms of a «Tragedy of High Prices» due to landings prices exceeding fishing costs at the socially optimal level of resource use. In tackling over-exploitation problems, the feasibility and relative efficiency of demand-side measures in attaining management objectives without necessitating introduction of other fishing rights is discussed. Distributional issues associated with using a market mechanism to allocate use rights and potential adoption of demand-side measures within a co-management framework are considered. Despite apparently desirable properties, solutions based upon demand-side regulation have been much neglected in the literature, and rarely put into practice. Discussion of such systems provides a contribution towards the continuing debate regarding how best to improve fisheries management, to ensure that economic rents are neither purely dissipated, nor simply captured by a first generation of resource users.
