Jeri Peck Multivariate Analysis for Community Ecologists: Step-by-step using PC-ORD™

Dr. JeriLynn E. Peck

As a research scientist in the School of Forest Resources, I split my time among applied research in forest ecology and providing training in community-level data analyses.

I've also written a textbook entitled Multivariate Analysis for Community Ecologists: Step-by-Step using PC-ORD.

Interests:

I teach short-courses for beginning use of the multivariate data analysis software PC-ORD, developed by my M.S. advisor Dr. Bruce McCune at Oregon State University. These trainings are intended to introduce multivariate statistical concepts, briefly describe each of the classification, ordination, and other tools available in the software, and train users in a data analysis approach and process applicable to community (species) datasets.

Lately, my research interests have turned to forest ecology with collaborations in the Applied Forest Ecology & Silviculture Lab at Penn State.

For the first 15 years, my research focused on all aspects of the commercial harvest of moss. This included species composition, biomass distribution, cover and biomass growth rates, post-harvest recovery dynamics, and alternative management approaches. After years of dedicated effort, I conclusively showed that moss does in fact grow slowly.
