- Abstract:
- ... Seagrass bed habitat is an important biotic community in decline worldwide. Boat damage has long been recognized for its negative impacts on shallow-water seagrass beds, with those along the Florida coast particularly vulnerable in the face of a large human population possessing a large number of boats. Boat scars to seagrass beds recover slowly, resulting in new damage that often outpaces recover ...

- Abstract:
- ... Two pasture growth models that shared many common features but differed in model complexity were refined for incorporation into the Integrated Farm System Model (IFSM), a whole-farm model that predicts effects of weather and management on hydrology, soil nutrient dynamics, forage and crop yields, milk or beef production, and farm economics. Major differences between models included the explicit re ...

- Abstract:
- ... Innovation and R&D in the complex agriculture-food industry enhance economic competitiveness and foster new food technologies, food safety, and value-added, healthful foods. A agricultural research is expected to integrate attributes such as using modern tools to improve process and product development and delivering nutrition and health by providing probiotics and prebiotics, phytonutrients, and ...

- Abstract:
- ... We analyze a bioeconomic model of a multiple-host disease problem involving wildlife and livestock. The social planner's choices include targeted (i.e., infectious versus healthy) livestock harvests, non-targeted wildlife harvests, environmental habitat variables, and on-farm biosecurity to prevent cross-species contacts. The model is applied to bovine tuberculosis among Michigan white-tailed deer ...

- Abstract:
- ... Some studies suggest that fishery yields can be higher with reserves than under conventional management. However, the economic performance of fisheries depends on economic profit, not fish yield. The predictions of higher yields with reserves rely on intensive fishing pressures between reserves; the exorbitant costs of harvesting low-density populations erode profits. We incorporated this effect i ...

- Abstract:
- ... Empirical models of crop––weed competition are integral components of bioeconomic models, which depend on predictions of the impact of weeds on crop yields to make cost-effective weed management recommendations. Selection of the best empirical model for a specific crop––weed system is not straightforward, however. We used information––theoretic criteria to identify the model that best describes ba ...

- Abstract:
- ... Insect derivatives represent an important innovation in specialty crop risk management. An active over‐the‐counter market in insect derivatives will require a transparent pricing method. This paper develops an econometric model of the spatio‐temporal process underlying a particular insect population and develops a pricing model based on this process. We show that insect derivatives can play an imp ...
