托福阅读文本:

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 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

rodents can also aid regeneration and dispersal of the oaks.

Their destructive powers are well documented. According to one report, squirrels 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 white 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, and are

therefore of no benefit to the trees. Flying squirrels, chipmunks, and mice are also unlikely to

promote tree dispersal, as they often store seeds in tree cavities and

underground burrows. Only

squirrels — whose behavior of caching (hiding) acorns below the leaf litter — often promote

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

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 towering 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, 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.
