John Spence

Job Title: Professor of Biological Sciences
Employer: Dept of Biological Sciences, University of Alberta
Further Education: Washington & Jefferson College (B.Sc.), University of Vermont (M.Sc.), University of British Columbia (Ph.D.).
Geographic focus of research: Alberta, British Columbia, Mexico, Kenya, Indonesia

Brief synopsis of current research:
My students and I work in three general areas bridging evolution and ecology:
1) structure and dynamics of arthropod populations,
2) integration of communities, especially those under anthropogenic influence and
3) the nature and evolution of arthropod species and their life-histories.
Our research program couples broad scientific objectives with the promise of shorter term applications in management and conservation of forests and wetlands. Work generally proceeds from a strong natural history base to develop experimental approaches to questions that apply to particular taxa. Generalization follows after common threads are discovered and confirmed experimentally.

Comments:
Nothing is half so much fun as splashing around in a pond or stream along with the other creatures that live there. Of course, water is touted to be the environmental problem of the coming few decades.
