Biology: Today’s technology plays a role in experiments
■ Continued from Page 1A
test Evolution, which is the devel
opment of a different reproduc
tive physiology.
Bill Rice, a biologist from the
University of California at Santa
Cruz, described how a mutant de
velopment of a big tail in certain
species of male birds serves to at
tract more females. Over time, fe
males in the same population
with the big-tailed males evolved
a decreased attraction to these
males with the bigger tails. Then
the males developed even bigger
tails, and the females developed
an even stronger resistance.
“There’s this arms race going
on between the sexes, and its by
product is reproductive isola
tion,” Rice said. "We’ve seen this
in guppies, which are very color
ful. They pay a price by increased
predation. Presumably they get a
big enough benefit in [number of
mates] that it makes it worth
while.”
Rice explained that in his ex
periment, forced monogamy was
used to determine whether ICE
was helpful or harmful to the
species a whole.
Rice put a male and female
mosquito together in a container.
“Males became nicer to females
[because] females didn’t have to
invest in not being hurt [by sever
al male mosquitoes harassing
them for sex],” he said. “We’ve
found that monogamous lives
produced more babies over time.”
If one defines “beneficial” as
having the greatest amount of off
spring produced, this finding
meant that evolution was not ben
eficial for the species, Rice said.
In all of the experiments the
speakers presented at the sympo
sium, technology was a large rea
son behind the experiments tak
ing place.
“A lot of the speakers were do
ing experiments that wouldn’t
have been possible even 10 years
ago.” said John Willis, a Universi
ty biology professor. “Now, be
cause of molecular biology tools
that are now available for all biol
ogists to use, we can answer all
sorts of questions.”
Lynch said he was excited by
the conference: “I think the excit
ing thing about this conference is
just the documentation of new ev
idence. Speciation is entering a
new era where we can do experi
mental work and test ideas.
There’s specific hypotheses that
allow us to go out and do critical
tests of these hypotheses.”
Crime: Three rapes have been reported near campus in two years
■ Continued from Page 1A
gravated assaults in 1994, seven in 1995
and only one in 1996.
In 1994, there were 252 thefts from cam
pus buildings. There were 194 thefts from
buildings in 1995 and 177 in 1996. Three
forcible sexual assaults occurred in 1996
and none in the two years prior.
There were three non-forcible sexual as
saults (also described as sexual abuse] in
1994, six in 1995 and seven in 1996, Guse
said.
According to information obtained from
Bev Mason of the Eugene Police Depart
ment, there were two reported rapes in the
campus area in 1996 and one in 1997. The
area runs north to south from Franklin
Boulevard to East 18th Avenue, and east to
west from Agate Street to Kincaid Street.
Guse said the victim of an attempted rape
has the edge in the situation in that the per
petrator has to hold the victim’s arms
down, cover the victim’s mouth to keep
him or her from yelling and also take the
victim’s clothes off, as well as his or her
own.
The biggest enemy of a potential victim
is fear, Guse said.
“The rapist is at the disadvantage,” he
said. “How is [the rapist] going to do that
unless he [or she] has fear working for him
[or her]?”
Guse said people should be aware of
their surroundings during evening hours or
when few people are around.
"Keep your mind about you,” he said.
“Think about things around you.”
Being prepared for a personal attack in
cludes being able to run from an attacker,
which begins with dressing appropriately,
Guse said.
“Don’t present yourself as a victim,” he
said. "Don’t dress in a fashion that will pro
hibit you from running,” he said.
OPS and the Eugene Police Department
have worked together to curb the number of
rapes and attempted rapes in the campus
area. Several years ago, numerous sexual
assaults were reported to have occurred at
a University parking lot at East 14th Av
enue and Kincaid Street during a short time
span, Guse said.
The two departments have made the
parking lot a 24-hour enforcement area, and
the number of reported assaults has
dropped to zero, Guse said.
Other areas of concern to local law en
forcement officials in the campus area dur
ing the past few years include theft, forgery,
drug abuse, vandalism and consumption of
alcohol by minors.
EPD statistics showed that students and
other residents in the campus area reported
152 thefts in 1996 and 106 in 1997. Four
teen forgery charges were reported in 1996,
and 12 were reported last year. The number
of drug abuse arrests rose slightly from
1996 to 1997, from 43 to 53.
Fifty-seven liquor violations were report
ed in 1996, and the number rose steeply to
80 last year. Residents reported vandalism
ten times in 1996 and 12 times in 1997.
