Research Area

Plant ecology and lichenology.

Description of Research

I work in three overlapping, interdependent areas:

Tools for analysis of ecological communities and habitats: My research on analytical tools concerns how species abundance as a response variable differs from the ideal variables, how this creates problems, how to deal effectively with those problems. My current research in this area focuses on species response surfaces in multidimensional predictor spaces.
Ecology of temperate forest epiphytes: My work in this area include basic research on the distribution, abundance, and dispersal limitations of temperate forest epiphytes and applied work on how changing forest practices will alter our future ecosystems. We have studied the long-term consequences of green-tree retention, how different species and functional groups of lichens are distributed in young, seemingly monotonous forests, and whether the structure of young forests be changed to enhance the re-entry and development of old-growth associated epiphytes.
Taxonomic syntheses of lichens in the Pacific Northwest: My work on regional lichen floras has been crucial to facilitating work on the ecology of lichens in the Pacific Northwest . Regional floras for macrolichens have been completed; work on crustose groups is continuing.
