The interactions between lichens and biofilms and to what extent lichens and biofilms protect or harm stone surfaces from weathering are questions that will be discussed.<br \/>\nLectures will cover basic lichen morphology and species identification; biofilm \u201cmorphology;\u201d the role of lichens and biofilms in the environment; basic geology; the history of stone quarrying, finishing, and construction; and the history and contemporary practices of preservation \u201ctreatments\u201d for stone.\u00a0 Field trips are planned for forest and shore environments, a granite quarry, a gravel pit, and several cemeteries.\u00a0 Examination and identification of lichens, biofilms, and stones will be undertaken in the field and in the laboratory.\u00a0 The impact of surface manipulation of stone (cutting, polishing, and chemical \u201ctreatments\u201d) and how these impacts may influence (or not) the growth of lichens and biofilms will also be examined.\u00a0 As a class project, participants will compile a checklist of the lichen species found during the field trips.<br \/>\nParticipants are expected to represent a wide variety of disciplines and avocations; the pursuit of individual interests will be encouraged.\u00a0 While prior knowledge of lichens, biofilms, or stone will be useful for this seminar, it is not necessary.<br \/>\n<b>Judy Jacob<\/b> is a Senior Conservator with the National Park Service, Northeast Region, in the New York City Field Office.\u00a0 She works primarily on stone monuments and masonry buildings: evaluating conditions, preparing preservation plans, and\u00a0executing stabilization and repair treatments.\u00a0 judithmjacob@yahoo.com<br \/>\n<b>Michaela Schmull<\/b>, PhD., is a lichenologist and the Research and Curatorial Associate at the Farlow Herbarium, Harvard University.\u00a0 Her research interests include lichen ecology, biodiversity, and systematics.\u00a0 She has taught classes in plant microscopy, plant identification, and lichens and air pollution.\u00a0 mschmull@oeb.harvard.edu<br \/>\nClass limit &#8211; 16 students<br \/>\nDaily meeting times &#8211; generally from 8:30 AM to 12:30 PM (lunch is at 12:30), 1:30 to 5:30 (dinner is at 7:00), from 8:00 onwards is optional, though most participants spend a few hours in the classroom after dinner for assignments and\/or independent studies.<br \/>\nActivities during the week generally combine intensive field studies and follow-up work in the lab with lectures, discussions, and a review of the current literature.
