OSU Lichen and Bryophyte Research Group

July 2003

From here you can access the following information about the OSU Lichen and Bryophyte Research Group:

• Purposes
• Structure
• Publications
• Gatherings
• Research Themes
• Members and their interests

This page was originally designed by Eric B. Peterson and Eric T. Peterson. Bruce McCune is doing updates. Direct questions, comments, or concerns about this page to him.

Purposes

• Facilitate communication
• Provide trainings and workshops
• Facilitate collaborative projects

Structure

The group is held together by common interests and exchange of ideas rather than by a formal organizational structure. Communication to the group can be directed through any of its members.

Publications

The group has no regular publication or newsletter. Rather, communication takes place largely through the peer-reviewed literature. Recent publications are available from the authors, or contact from Bruce McCune.

Gatherings

• Weekly seminar/discussions (see photo above).
• Northwest Lichen Guild. The Northwest Lichen Guild meets yearly, in conjunction with the Northwest Science Association in March.

Research Themes

• Effects of alternative forest management practices on epiphytes
• Conservation of rare, threatened, and endangered species
• Taxonomy and systematics of lichens and bryophytes
• Use of lichens as indicators of air quality
• Lichen transplants in contrasting habitats
• Analysis of lichen community composition
