NEWS!

Nathan Lojewski's paper is now out in Tree Phys!

New paper by Bailey et al. compares genes to ecosystems effects above vs. belowground! Whoa!

New Whitham et al. book chapter takes a conservation approach to considering genes to ecosystems effects!

EEON is now fully

operational! See link under "Research"

Ph.D., Faculty

Forest Ecosystem Ecology

WELCOME

I am a faculty member at The Evergreen State College where teach plant and forest ecology. Some recent classes include, Field Ecology, Plant ecology and Physiology, Writing on the Wild Side, Temperate Rainforests, The Olympic Peninsula, Genes to Ecosystems, Educating on the Wild Side, and Introduction to Environmental Studies. Over the next two quarters (Winter/Spring 2010) I will be teaching Sustainable Forestry, and another new program called Plant Ecology Afield. Next year (2010-11) I will be teaching Field Ecology with Alison Styring (Ornithology faculty).

I also manage a small undergraduate field lab, the field and ecosystem ecology lab. The lab has done some really fun work in diverse ecosystems, and we manage the evergreen ecological observation network (a network of permanent plots in the campus forest- EEON).

If you are curious about my research, check out the lab page with links to work on tree water use, effects of plant genetic variation on ecosystem function, carbon flux, and belowground ecology.

My research work has focused on ecosystem function and community-ecosystem inter-actions. A lot of my research is on trees because they have a large effect on carbon, water and nutrient dynamics in forest ecosystems. I like to address questions about how variation among trees affects communities and ecosystems in terms of water, carbon, and nutrient dynamics. I have worked extensively with a multidisciplinary working group using cottonwood riparian forests as a model system for understanding how intraspecific variation scales to affect ecosystems. I have also employed specialized technology to measure whole-tree and leaf-level physiology, fine-root dynamics, and ecosystem carbon flux. Current work in our undergraduate-focused Field and Ecosystem Ecology lab (see link) is divided between cottonwood forests (From Washington to Arizona), prairies of the south Puget Sound, and temperate rain-forests in western Washington. I'm really excited about the work we've been doing recently estimating carbon budgets for diverse second-growth rainforests. For more on this topic, check out the links to the EEON project. My lab also continues our exciting collaborations with an international working group in understanding how genetics affect ecosystems using native Cottonwood forests. Please check out our other websites for more on this topic:
