The New England Botanical Club (NEBC), founded in 1895, is a non-profit organization promoting the study of plants of North America, especially the flora of New England and adjacent areas. The Club publishes the peer-reviewed journal Rhodora, holds monthly meetings during the academic year (usually at Harvard University, Cambridge, Massachusetts), maintains an herbarium of more than 253,000 sheets, has a small library, and annually grants research and publication awards.

Abstract: "Climate Change, Local Adaptation, and Arctic Plant Communities"
Arctic plant species are clearly well-adapted to the extremes of the arctic environment, and often show significant within-species or ecotypic differences in relation to local or regional variation in topography and microenvironment. Arctic vegetation is also highly variable and can be dominated by tall or creeping deciduous or evergreen shrubs, grasses or sedges, mosses or lichens, or a wide range of mixed "functional type" communities. Does all of this variation in vegetation composition make any difference to how arctic ecosystems function in terms of their productivity, biogeochemistry, or responses to climate change? This talk will review some of the evidence for variation in functional responses of arctic ecosystems and relationships between vegetation composition and ecosystem function. The talk will end with a discussion of how different kinds of arctic vegetation, and individual species, might respond differently to climate change.
Dr. Gus Shaver is a plant ecologist with over 40 years of experience working in Alaska and in arctic tundra ecosystems. Early work focused on adaptations of tundra plants to the arctic environment; gradually this focus has expanded to encompass the broad role of plants in arctic carbon and nutrient cycles and especially the interactions between carbon and other elements in plants as limiting factors to productivity and organic matter accumulation. Current interests include the growing role of climate change-related disturbances, such as wildfire and thermokarst in a warmer Arctic.
Shaver currently leads the Arctic Long Term Ecological Research Project, based at Toolik Lake, Alaska. Since 1979 he has worked at The Ecosystems Center in Woods Hole, MA, where he is now a Senior Scientist. Early training was at Stanford (BS, MA, 1972) and at Duke University (PhD, 1976).
