Ecosystem Evolution Chronicled Over Three Generations

Pristine Siberian Lake Undergoing Changes

Utica, NY (04/20/2009) - It is often referred to as the aquatic version of the Galapagos Islands. With its 1,500 endemic species and the world’s only known freshwater seal, Lake Baikal in subarctic Siberia is the world’s largest, deepest and most biodiverse lake. The lake’s volume of water exceeds the combined volumes of the North American Great Lakes and its area covers over 19,000 square miles. But even this behemoth, static and seemingly stable ecosystem is experiencing changes brought on by climate change.

Marianne Moore, associate professor in the department of biological sciences at Wellesley College, will present her lecture about the changes in Lake Baikal and its surrounding environs when she presents Tales from Siberia: Climate Change and the World’s Greatest Lake on Monday, April 20, at 4 p.m. in Macfarlane Auditorium, DePerno Hall. The lecture is part of the Asa Gray Lecture Series and is free and open to the public.

Moore will recount her analyses of the data from three generations of a Russian scientific family. The data show that despite Lake Baikal’s enormous volume and eons of thermal inertia, the lake is responding strongly to contemporary climate change.
