Beneath the Connecticut River
In 1994, Dr. Ed Klekowski began exploring the Connecticut
River which rises in northern New Hampshire and, on
its way to LI Sound, passes through Vermont, Massachusetts, and
Connecticut.
Using scuba gear, Ed and a team of colleagues, and
undergraduate and graduate students have come upon what appear to
be an old dam, pieces of a train, the remains of a railroad trestle
thought to have been ripped from its moorings by the flood of 1936, and
remnants of the nation’s oldest canal built in 1792-95 near South Hadley.
They have recovered anchors and variously colored glass elixir bottles.
In August 1997, diving team members, grad students Monica O’Guinn and
Sean Werle, discovered a 120-foot-deep abyss. It was named King Philip’s
Abyss in homage to Metacomet, the Wampanoag Indian chief who fought to
drive English colonists from the Connecticut River Valley. Denizens of
the river encountered by Ed and his divers include the yellow lampmussel,
Lampsilis cariosa, a freshwater clam (figured right) thought to have
disappeared from the river 30 years ago, sponges the size of dinner
plates, flatworms, mussels, eels, wall-eyed pike, and an abundance of the
large green alga Chara as well as the bryozoan Pectinatella
magnifica, a primitive filter-feeding animal. Clay deposits at
the bottom of the river have yielded a new species of red bloodworm,
Axarus varvensis.
On the bottom of the deepest parts of the river, Ed and his
team have come upon varves, large stratiform sediments of clay and silt that
were apparently formed when, with the waning of the most recent ice age, a
massive body of water known as Lake Hitchcock (map right) covered the area between
New Britain, CT and St. Johnsbury, VT.
Some of the artifacts reclaimed from the bottom of the
river are currently on display at the Springfield Science Museum.
The exhibit, entitled "The Underwater World of the Connecticut River",
features an eight-minute
videotape that focuses on the archaeological, biological and historical
treasures of the river. The exhibit is the first collaborative effort between
the Springfield Science Museum and the University of Massachusetts, Amherst.
Another display documenting the underwater world of the Connecticut was
exhibited at the Connecticut River Museum in Essex, CT last summer.
The underwater exploration of New England’s largest river has led to
the construction of a web site by Ed and project historian Libby Klekowski.
It offers much interesting information
about the biology, history and geology of the Connecticut River, URL:

Darwin Fellows Enhance Biology
Family
The Darwin Fellows Program, now in its fourth year, brings promising young
postdoctoral researchers to the Organismal and Evolutionary Biology (OEB)
Program at UMass Amherst. The Darwin Fellows Program awards two two-year
fellowships and enables the recipients to undertake a unique combination of
teaching and research responsibilities that are excellent
preparation for academic positions. The fellowship program embodies
the interdepartmental collaboration that characterizes the OEB Graduate
Program. Darwin Fellows are active participants in OEB, acting as mentors
to graduate students, conducting research, leading seminar courses, and
teaching courses in the Biology Department.
Our current Darwin Fellows are Dr. Andrew Hendry, and Dr. Jim
O'Reilly. Dr. Hendry (right, with whale bones)
is an evolutionary ecologist with a B. S. from U.
Victoria, BC, and a M. A. and Ph.D. from U. Washington, Seattle. His
research interests include (1) interactions between selection
and gene flow during adaptive population divergence, (2) spatial and temporal
scales of population structure, and (3) patterns and rates of micro-evolution
in contemporary populations. Through collaboration with other biologists,
Andrew's work integrates theoretical modeling, molecular genetics, field
and laboratory experiments, and surveys of biological diversity at varying
scales. Dr. O'Reilly (right, with a caecilian, a tailless legless amphibian) earned his Ph.D. at Northern Arizona
University.
Jim taught comparative vertebrate anatomy in the spring of 1999 and 2000. His research interests include
(1) the evolution of the physiological basis of
movement in vertebrates, (2) the emergence of novel complex functional
systems during vertebrate evolution, and (3) the natural history of reptiles
and amphibians.
Previous Darwin Fellows, who have moved on to positions at other institutions,
are:
Dr. Karen Kellogg, Ph.D. Penn State University '97, is a
behavioral ecologist studying the evolutionary processes that gave
rise to the diverse cichlid fishes of Lake Malawi, Africa. She is
currently a Teaching Associate in the Environmental Studies
Program at Skidmore College where she is
helping to establish the environmental studies major. Dr. Andrew Simons, Ph.D.
University of Alabama, is a molecular systematist who investigates
the evolution, morphology, behavior, and biogeography of fish. He is an
Assistant Professor in the Department of Fisheries and Wildlife at the
University of Minnesota. Dr.
Alison Hunter has a Ph.D. in ecology from McGill University (`92); her
background is in terrestrial population and community ecology. She is
currently Research Assistant Professor at the University of Notre Dame.
Dr. Paul Morris, Ph.D. Harvard `91, specializes in invertebrate
paleontology. Currently, Paul is the Academy Malacologist at The Academy
of Natural Sciences in Philadelphia.
It is clear, that by providing growth opportunities to biologists at the
beginnings of their careers, the Darwin Fellows Program has enriched the
entire biology family.
