The objective of this study was to evaluate how northern flying squirrels (Glaucomys
sabrinus) locate truffles (Gautieria monticola),a subterranean and ephemeral but primary food
source.Thus,we evaluated the importance of three factors to the foraging behavior of
northern flying squirrels:(i) olfactory chemicals that emanate from truffles; (ii) the presence of
coarse woody debris (decaying logs),which are often associated with fungi; and (iii) we
explored the potential role animal memory could play in truffle detection as well.In a foraging
arena,squirrels successfully retrieved buried truffles that lacked aboveground cues in 19 of 30
trials and failed to search near treatments that lacked truffles altogether,confirming the
importance of olfaction to squirrel foraging.However,squirrels also retrieved truffles that were
associated most frequently with surface logs (27 of 30).In addition,the initial detection rate of
the truffle + log treatment was significantly greater than the truffle-only treatment.Thus,
although squirrels search for truffles primarily using olfaction,they may also benefit by
searching near coarse woody debris on the forest floor as an aboveground cue to truffle
locations.In addition,because 82% of Sierra Nevada truffle-fruiting locations that were marked
in 1996 yielded truffles again the following 2 years,mycophagous animals like northern flying
squirrels may benefit by memorizing fruiting locations and foraging at these same locations
from year to year.
如果太长，给出大体思路能看懂就行，

大概是讲：本次研究的目的是评估北鼯鼠（ Glaucomys sabrinus ）的觅食行为.比如它们找到松露（ Gautieria monticola ）的方式.评估北鼯鼠觅食行为重要的三个因素：1.通过嗅觉触到从松露中所发散的化学物质; 2.通过往往是伴有真菌存在的腐朽木质;3.从探索以及对松露检测中发现通过动物的潜在记忆寻找.在30次的实验当中有19次松鼠成功的找回了被埋藏起来的松露,也遇到了失败.这样就确认了嗅觉在松鼠觅食当中有着十分重要的作用.然而,在30次的27次实验当中松鼠都能从粗木质残体中找到松露.就是说,寻找松露和粗木质残体比只是寻找松露更有效.因此,虽然松鼠寻找松露主要使用嗅觉,但是他们也可能从粗木质残体中受益,在森林的地面上寻找附近地上的松露.
最后一些话强调松鼠通过记忆力在原来发现松露的地方继续寻找松露.
