Combining Heterogeneous Data in Ecology and Natural Resources

Spring 1999

Fisheries and Wildlife 893 - Section 602

Instructors: Ace Sarnelle and Jim Bence

Meets Tuesday 2:30 PM, 206 Natural Resources Bldg.

This seminar will explore cutting edge methods for combining data from multiple sources to answer questions in ecology and natural resource management. Emphasis will be on meta-analysis, an approach to combining a number of individual studies to come to a single answer or estimate. The seminar will concentrate on conceptual issues and current applications. A central issue we will start with is defining our biological question in quantitative terms suitable for meta-analysis. Other issues include how to select studies to include in the meta-analysis, how to deal with differences in methodology, literature bias, and treatment of multiple sources of variability. Each student will give one or more presentations based upon either current literature or a meta-analysis application of their own design.
