Ecologist (Research)

Primary Responsibilities: 
Ecologist (Research), Quantitative Methods Unit, 1988-Present.  
Duties include field and statistical research on U.S. wildlife and habitats, review of study plans and manuscripts, experimental design, statistical consulting with wildlife biologists, and data analysis. Current research consists of integrating population viability analysis (PVA) and adaptive management, as applied to the Florida population of whooping cranes, monitoring growth and survival of Hawaiian trees, monitoring regeneration and restoration of vegetation in Texas, analysis of inventory data for eastern-region national parks, and estimating detection probabilities for golden-cheeked warblers in Texas.

Education/Training: 
B.A., Miami University, 1979, zoology and mathematics

M.S., Miami University, 1981, zoology

M.A.S., Ohio State University, 1982, applied statistics

Ph.D., Ohio State University, 1986, biostatistics

Active Projects: 

Effectiveness of vegetation-based approach to monitor vertebrate resources

Estimating detection probabilities of golden-cheeked warblers

Growth and survival of trees in Hawaiian montane rain forest

Vegetation monitoring at Balcones Canyonlands National Wildlife Refuge

Adaptive management of releases to the Florida nonmigratory whooping crane population: Integrating population viability analysis with decision theory
