Theoretical Ecology, Conservation Biology


Dr. Jager’s sustainability research seeks to quantify ecosystem services provided by energy alternatives (hydropower and bioenergy) so that they can be brought into the decision-making arena.

  • Bioenergy: We are working at regional and local scales to find opportunities to maximize support for ecosystem services (e.g., wildlife habitat and improved water quality). At a regional scale, we are evaluating the potential for improving water quality by growing 2nd generation perennial crops in the Mississippi River basin. We are also evaluating National-scale projections for biodiversity of bird species. At a farm scale, we will be evaluating practices that enhance ecosystem services.
  • Hydropower: We are using population models to evaluate conservation practices (e.g., trap-and-transport operations, passage facilities, screens, and hatcheries). This research has produced practical guidelines for how far apart dams should be spaced, when and where to provide up- and down-stream fish passage, and whether hatcheries should collect larvae or broodstock adults to minimize genetic and demographic risks. A new effort is evaluating proposed recovery plan alternatives using a spatially explicit and individual-based demo-genetic model to evaluate a salmon ESU being considered for delisting under the Endangered Species Act.
