recommend that you contact professor Mark McKone of Carleton College. He
is managing the college's arboretum to restore the prairie and oak savanna
composition that existed here before fire supression. The area is
a particularly interesting study site because it borders the western
boundary of the Minnesotan prairie/oak savanna (cerca 1860).
Professor McKone can be reached by e-mail:

Subject: CARP EAT ZEBRA MUSSELS
National Biological Service
For Immediate Release Contact: Steve Gutreuter
608/783 7550, ext. 58
October 19, 1995 John Tucker 618/466 9690
COMMON CARP MAY FIND ZEBRA MUSSELS A TASTE TREAT
The surprise came one day this summer when John Tucker, a biologist with the
Upper Mississippi River Long Term Resource Monitoring Program Alton, Ill.,
Field Station, was fishing with his daughter at Brussels Ferry, Ill. According
to Tucker, he and 11-year old Moynell M. Tucker caught a 12-inch carp, and to
satisfy her scientific curiosity, "Moynell insisted on taking it home to
dissect." At home, Tucker and his daughter examined the gut contents of the
common carp. To Tucker's surprise, "The fish's gut was completely packed with
fragments of zebra mussels." Zebra mussels are the "exotic" species of mussel
transported from Europe via shipping boats to the Great Lakes in 1988, and are
of concern because of their potential economic and ecological impacts on the
Upper Mississippi and other rivers.
Because the common carp, itself an exotic species, has not been reported to
feed extensively on this newly introduced mussel species in the United States,
Tucker approached Alton Field Station colleague Fred Cronin with news of his
discovery. Subsequently, field station biologists collected a series of common
carp specimens from the Mississippi River, just below the confluence with the
Illinois near Grafton, Ill. This collection site has been monitored for zebra
mussels since 1992 and is known to be heavily colonized by them.
Thirty-one common carp were collected at River Mile 217; twenty-six contained
from 1 to 204 zebra mussels. With few exceptions, the shells were crushed and
well fragmented, but the beaks (the pointed end of the mussel that attaches to
rocks) were intact. Tucker reports that the field station has saved the beaks
for future measurement. "Because there is a straight-line relationship between
the length of the beak and the length of the zebra mussel itself, we will be
able to determine the size of the zebra mussels each carp had eaten."
Tucker believes that because the common carp is both widespread and numerous,
its potential impact on zebra mussel populations is worth investigating. Dr.
Steve Gutreuter, who directs monitoring and research at NBS's Environmental
Management Technical Center in Onalaska, Wisc., agrees that further
investigation appears warranted, cautioning that "it is far too soon to tell
whether carp might help control zebra mussel populations."
Some scientists propose importing potential zebra mussel predators in an
attempt to control the exotic mussels, which concerns Tucker. "Two common
Upper Mississippi River System species have already been found to eat zebra
mussels_freshwater drum and now the common carp. The ability of these species
as control agents should be investigated before other exotics are imported."
Zebra mussels, recent invaders in North America, probably came from the Black
and Caspian Seas by way of ship ballast water discharge. Since they were first
seen in the Great Lakes in 1988, they have spread to 19 states. Before recent
sightings in California, the U.S. range was from Lake Champlain in the
northeast, across the Great Lakes, west through the Mississippi River system,
and south to the Gulf of Mexico.
Zebra mussels can attach themselves to boat hulls and move as stowaways up and
down major rivers. The mussels can then spread because they may fall or be
scraped off to start new populations. Under moist and reasonably cool
conditions, zebra mussels can stay alive for several days out of the water.
The spread of zebra mussels is feared by cities and industries. The mussels are
notorious for colonizing and plugging water intakes at power plants and water
treatment plants, and in other facilities using fresh water. Cleaning and
treatment of these facilities is costly. For example, plant redesign and zebra
mussel control for 72 nuclear and fossil fuel generating plants in the Great
Lakes Basin is anticipated to cost in excess of $860 million over the next 10
years. Municipalities and industries in the region are also projected to spend
another billion dollars controlling mollusk growth over the same period.
Scientists, navigators, boaters and farmers are concerned over the effects
zebra mussels could have on natural ecosystems, river navigation, recreational
boating and agricultural irrigation.
The zebra mussel's specialized talents make it a hardy and tenacious traveler.
This fact, coupled with its recent appearance in California, strongly suggests
that the zebra mussel poses a real threat to habitable waters in virtually
every region of the United States. Large populations of unionid mussels have
already been lost in the Great Lakes from zebra mussel colonization on native
mussels.
The Long Term Resource Monitoring Program is administered by the Environmental
Management Technical Center, a National Biological Service Science Center. The
Monitoring Program is a cooperative effort by the National Biological Service,
the U.S. Army Corps of Engineers, and resource management and research agencies
of the five Upper Mississippi River Basin states of Illinois, Iowa, Minnesota,
Missouri, and Wisconsin. The Monitoring Program maintains field stations in
each of the partner states. The Environmental Management Technical Center,
located in Onalaska, Wisc., manages the largest river-related inventory and
monitoring, research, spatial analysis, and information management and sharing
program in the United States.
The National Biological Service of the U.S. Department of the Interior was
established to work with others to provide the scientific understanding and
technologies needed to support sound management and conservation of America's
biological resources.

Excuse me, but what is this snotty attitude about people in the field of
environmental science? My B.S. in E.S. included the same classes as my
biology brethren, in addition to chemisrty, geology, economics, marine
science, and two independent research projects before I was done. I had
absolutely no problem getting into a good Ph.D. program in biological
oceanography (with funding no less). When I found that this same snotty
attitude existed among the people in that field, I came back to E.S. at
the graduate level (same department). I take the same classes as all of
the rest of the people in department who are in somewhat different fields
give or take a few electives.
I think that many others out there who also consider themselves
environmental scientists will take huge offense at the description of
E.S. as a "lightweight" field by someone on this list. For heavens sake,
why don't YOU "lighten up"?
Forgive the cliche, but:
A mind is like a parachute. It only functions when it is open.

National Biological Service Joins Federal Science Information Group
The National Biological Service has been invited to join CENDI, a federal
interagency organization that works to improve the sharing, exchange, and
dissemination of scientific and technical information, Assistant Director for
Information and Technology Services Gladys Cotter announced. The acronym,
"CENDI," is derived from the names of participating federal agencies.
CENDI was formally established in 1984, when the Departments of Commerce
(National Technical Information Service), Energy, Defense (Defense Technical
Information Center), and the National Aeronautics and Space Administration
(NASA) agreed to increase federal research and development productivity by
improving the management and dissemination of scientific and technical
information. Since its establishment, membership has been expanded to include
the National Institutes of Health (National Library of Medicine), and the
National Air Intelligence Center. The NBS is the first bureau from the
Department of the Interior that will join CENDI.
"We are excited to join this collaborative partnership," said Cotter. "The
fact that we can work together, share expertise, and reduce expenditures on
these activities will greatly improve our ability to make biological data and
information more accessible to anyone who needs it."
CENDI member agencies cooperate on a broad array of issues and activities
to
make scientific and technical information more accessible within the government
and to the public. Activities include joint projects to develop technical
information directories and locator systems, joint standards for cataloging and
indexing, and to share costs and experience on new technologies for data and
information exchange and networks. In addition, the group will provide user
training and support through workshops and conferences. CENDI also plays a
leadership role on information issues with many other non-member agencies and
non-federal institutions. In Fiscal Year 1995, there were more than 27
external
cooperating organizations in CENDI activities and programs. The CENDI Internet
home page can be found at http://www.dtic.dla.mil/cendi/
The National Biological Service of the U.S. Department of the Interior
works
with others to provide the scientific understanding and technologies needed to
support the sound management and conservation of the nation's biological
resources. The National Biological Information Infrastructure (NBII) is an NBS
initiative to foster the development of a distributed electronic network of
biological data and information maintained by a variety of federal and state
government agencies, universities, museums, libraries, and private
organizations. The NBII is available on the Internet at http://www.nbs.gov/
