Current Students

Martin Hutten Martin is an avid bryologist and lichenologist who also happens to work for the National Park Service, taking on the noble work of fighting weeds and promoting biodiversity. Currently at Yosemite National Park and pursuing a PhD at Oregon State University, Martin has also worked extensively at Olympic National Park and at Craters of the Moon, among many other places. If you google Martin you will also find that he is a great photographer. He was the lead author and photographer for the hard-to-find pocket guidebook, "101 common mosses, liverworts, and lichens of the Olympic Peninsula." (see below).

Peter Nelson Before beginning grad school Peter worked for years with lichens for the Forest Service's Air Resources projects in the Pacific Northwest.Peter has also worked on developing macrolichen identification resources in both English and Spanish or the Valdivian temperate rainforests of Chile. His thesis project delves into the relationship between caribou and vegetation in Denali National Park, Alaska. This work will use remote sensing and habitat modeling to integrate a vegetation sampling program with caribou location data, with particular emphasis on late-season and winter habitat and snow patterns.

Heather Root Heather came to us from SUNY - Syracuse, where she earned a masters studying epiphytes and invertebrates in relation to silviculture in the Adirondack Mountains. Heather is pursuing a master's in Statistics and a PhD in Botany. Her projects in Oregon include comparing statistical power of nonparametric methods for testing multivariate differences among groups with community data and exploring the fundamental properties of community data. She is also a field botanist, and is remeasuring and analyzing lichen communities after 13 years of the Density Management Study. See Heather's website.

Heather Lintz Heather completed a M.S. in Botany at OSU in 2005, working with Mary Kentula and Mark Wilson. She began working on a PhD in our department in 2006. Heather is unusual among my students in not working on lichens; instead, she works on the basic mathematical properties of species response functions, as applied to tree species distribution in the Pacific coastal states. She is also interested in species traits as predictors of community structure, as applied to wetland plants, including bryophytes. Heather won the E. C. Pielou Award from the Statistical Section of the Ecological Society of America in 2006 for the best student presentation, "Threshold strength and 'diagonality': response descriptors for comparison of empirical model types." See Heather's website.

Shanti Berryman Shanti did lichen field work for years in the Gifford-Pinchot National Forest before coming to OSU. She studied the biomass and community composition of lichens in different stand structures in the Blue River Landscape Project. These data allowed us to evaluate the long-term consequences of alternative management strategies. Shanti received the Goward Prize at the Northwest Lichen Guild meeting in 2000 and the A. J. Sharp award at the ABLS meeting in 2000. She received her PhD in 2002 and is field-certified in macrolichens west of the Cascade Crest by Northwest Lichenologists. Since her PhD Shanti has worked on lichens and air quality in Alberta, and as a research associate in the Forest Science department at OSU.

Amanda Hardman Amanda has a keen interest in bryophyte taxonomy and ecology. She began as a graduate student in 2006, after many seasonal jobs as a botanist with federal agencies. Her thesis project concerned responses of soil-dwelling bryophytes to disturbances (fire, logging, and grazing) in dry forests east of the Cascade crest. She also has a special interest in Sphagnum in Oregon. Currently Amanda is employed in botanical survey work.

Sarah Jovan Sarah helped Andrea Ruchty with her field work for a summer, then worked on various projects, including lichens and fungi, before beginning her graduate program in 2001. During her work with Andrea, she completed a project comparing bark pH of selected tree species in Oregon, and observing the influence of mixed canopies on bark pH. For her PhD thesis (2005), Sarah developed gradient models for communities of epiphytic macrolichens in California. Sarah won the Oregon State University Yerex Award in 2004 and the Goward Prize at the Northwest Lichen Guild Meeting in 2002. Sarah currently works on a cooperative project between OSU and the USFS on lichen community data collected in the Pacific coastal states for the FIA program.

Erin Martin Erin came to Corvallis from Boise State University, where she worked in the lichen herbarium for Roger Rosentreter, in the field with Julie Kaltenecker, and doing her own undergraduate lichen project. She assisted Jenifer Hutchinson in her summer fieldwork in northern Idaho, then became an accomplished TLC artist, working mainly on Hypogymnia with Bruce. Erin completed her PhD in 2005, working on habitat models predicting occurrences of survey-and-manage species on the west slope of the Cascades in Oregon. In 2004 Erin won the A. J. Sharp Award at the American Bryological and Lichenological Society meeting, for best student paper. Erin currently teaches at Shasta Community College in California. See her website.

Peter Neitlich Peter was not officially my student, but I worked with him during his masters project out of the University of Vermont and the H. J. Andrews Experimental. Forest. Since then he worked with me on studies for the BLM, including the pioneering work on the importance of hardwoods for epiphytes in otherwise monotonous young conifer forests. He has served as "Indicator Lead" for the Forest Health Monitoring (FHM/FIA) program in western U.S. He now works for the National Park Service in Alaska and Washington.

JeriLynn Peck Jeri worked with me for quite a while on diverse array of projects, including being my right arm during the most intense period of activity on Lichen Communities as an indicator in the Forest Health Monitoring program. She completed a masters in 1996 on harvestable moss in western Oregon. She is the most knowledgeable person on this topic in the Pacific Northwest. She has worked on this from all angles, having worked with harvesters, land management agencies, as well as the academic side of biomass accumulation in epiphytic moss mats. See her list of publications on commercial moss harvesting in the Pacific Northwest. Jeri is currently working on a PhD program at the University of Minnesota.

Eric B. Peterson Eric studied lichen distribution and abundance in relationship to forest structure and management, modelling the probability of species occurrences at the landscape level, and ecology and systematics of calicioid fungi and lichens. Eric received the Goward Prize at the Northwest Lichen Guild meeting (1998). He is field-certified in macrolichens west of the Cascade Crest by Northwest Lichenologists. Eric currently works for the Natural Heritage program in Nevada.

Jeanne Ponzetti Queen of the biotic crusts of eastern Oregon and Washington, Jeanne was unusual in having chosen to work in the steppe. She completed her thesis on the relationships of grazing, climate, and soils on biotic crusts in Oregon. Immediately after her thesis she studied the distribution, abundance, and composition of biotic crusts at Horse Heaven Hills near Kennewick, Washington. Since her time at OSU she has worked as a botanist for the BLM in Eugene, Oregon, and Ellensburg, Washington.

Tom Rambo Not really my student (he was Pat Muir's), I've worked with Tom a lot so it seems like he's part of this list. Tom's forte is forest floor and epiphytic bryophytes, but he's also good with lichens. He's also a top-notch tree climber (though he points out this is "ascending" not "climbing"). Tom finished his Master's thesis in 1998. Tom is currently working on a PhD at UC Davis in California.

Abbey Rosso Abbey finished a Ph.D. project studying epiphytes on shrubs in forests in western Oregon. In addition to collecting lichens, she also collects awards, including the Oregon Sports Scholarship (1996), the Yerex Scholarship (1997), and the Goward Prize at the Northwest Lichen Guild meeting (1997). She is field-certified in macrolichens west of the Cascade Crest by Northwest Lichenologists.

Andrea Ruchty Andrea studied riparian lichens in the Coast Range of Oregon, finishing her master's thesis in 2000. In particular, how do different canopy types influence epiphytic lichens? She is also worked with Abbey Rosso and Bruce McCune on the dynamics of shrub epiphytes. Like her namesake, the moss Andreaea, she is tenacious in demanding environments. She is field-certified in macrolichens west of the Cascade Crest by Northwest Lichenologists. Andrea currently works for the Gifford-Pinchot Nationial Forest in Washington.
