Naturalists and casual observers alike have been struck by the special relationship
between squirrels and acorns (the seeds of oak trees). Ecologists, though, cannot observe
These energetic mammals scurrying up and down oak trees and eating and burying acorns
without wondering about their complex relationship with trees. Are squirrels dispersers
(5) and planters of oak forests or pesky seed predators？ The answer is not simple. Squirrels
may devour many acorns, but by storing and failing to recover up to 74 percent of them
(as they do when seeds are abundant), these arboreal o\rodents can also aid regeneration
and dispersal of the oaks.
Their destructive powers are well documented. According to one report, squirrels
(10) destroyed tens of thousands of fallen acorns from an oak stand on the University of
Indiana campus. A professor there estimated that each of the large while oaks had.
Produced between two and eight thousand acorns, but within weeks of seed maturity,
Hardly an intact acorn could be found among the fallen leaves.
Deer, turkey, wild pigs, and bears also feed heavily on acorns, but do not store them,
(15) And are therefore of no benefit to the trees. Flying squirrels, chipmunks, and mice are
Also unlikely to promote tree dispersal---whose behavior. of caching (hiding) acorns below
The leaf litter often promotes successful germination of acorns---and perhaps blue jays,
Important long-distance dispersers, seem to help oaks spread and reproduce.
Among squirrels, though, there is a particularly puzzling behavior. pattern. Squirrels
(20) pry off the caps of acorns, bite through the shells to get at the nutritious inner kernels,
and then discard them half-eaten. The ground under towing oaks is often littered with
thousands of half-eaten acorns, each one only bitten from the top. Why would any animal
waste so much time and energy and risk exposure to such predators as red-tail hawks only
to leave a large part of each acorn uneaten？ While research is not conclusive at this point,
(25) one thing that is certain is that squirrels do hide some of the uneaten portions, and these
acorn halves, many of which contain the seeds, may later germinate.
What does the passage mainly discuss？
A．The ecology of oak trees
B．Factors that determine the feeding habits of Squirrels
C．Various species of animals that promote the dispersal of tree seeds
D．The relationship between squirrels and oak trees
W: Yeah. I waited for an hour to sign up for a distance learning course.
M: Distance learning？ I've never heard of it.
W: Well, it's new this semester. It's only open to psychology majors. But I bet it'll catch on elsewhere. Yesterday over a hundred students signed up.
M: Well, what is it？
W: It's an experimental course. I registered for Child Psychology. All I got to do is watching a twelve-week series of televised lessons. The department shows them several different times a day and in several different locations.
M: Don't you ever have to meet with your professor？
W: Yeah. After each part of the series, I have to talk to her and the other students on the phone, you know, about our ideas. Then we'll meet on campus three times for reviews and exams.
M: It sounds pretty non-traditional to me. But I guess it makes sense considering how many students have jobs. It must really help with their schedules. Not to mention how it'll cut down on traffic.
W: You know, last year my department did a survey and they found out that 80% of ail psychology majors were employed. That's why they came up with the program. Look, I'll be working three days a week next semester and I will either cut back on my classes or try this out.
M: The only thing is, doesn't it seem impersonal though？ I mean, I miss having class discussions and hearing what other people think.
W: Well, I guess that's why phone contacts are important. Anyway it's an experiment. Maybe. But I'll be curious to see how it works out.
What is the relationship between the two speakers？
A．They have not met ever before.
B．Teacher and student.
C．They are schoolmates.
D．They are classmates.
