May Speaker-Weds Evening, May 21st


Guest Lecturer Professor Richard Primack to Speak at Garden Club of Concord Annual Open Meeting

Professor Richard B. Primack, an environmental biologist, will be speaking on “Climate Change in Thoreau’s Concord” on May 21st, at Trinitarian Congregational Church, 54 Walden Street, at 7pm.

Professor Primack is currently investigating the impact of climate change on the flowering and leafing out times of plants; the spring arrival of birds and the flight times of insects in Massachusetts, Japan, and South Korea; and the potential for ecological mismatches among species caused by climate change. The main geographical focus is Concord, Massachusetts, due to the availability of extensive phenological records kept by Henry David Thoreau and later naturalists. He is using Concord as a living laboratory to determine the effects of climate change species, and land use changes on the population dynamics of native and non-native species. He is also comparing results from Concord with long-term changes at Acadia National Park in Maine. An expanding interest is the variation among species in leafing out times and leaf senescence times, and the physiological control of these processes. Primack serves as Editor-in-Chief of the international journal Biological Conservation.
