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.

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.

这项研究的目的是评估北部飞行的松鼠（ Glaucomys sabrinus ）如何找到松露（ Gautieria monticola ） ，一个地下的和短暂但主要食物来源。因此，我们评估三个因素的重要性：（一）嗅觉的化学品，源自松露（二）存在粗木质残体（腐朽的日志） ，这往往是伴有真菌; （iii）我们探讨的潜在作用动物记忆体可以发挥在松露检测作为。在一个觅食阶段，成功松鼠检索埋葬松露缺乏地上线索，在19/ 30次试验和失败的治疗，完全缺乏松露，确认嗅觉的重要性松鼠觅食附近搜索。然而，松鼠也检索松露最常相关与表面的日志（ 27 30 ） 。此外，松露+日志处理的初步检出率显著大於松露唯一的治疗方法。因此，虽然松露的松鼠搜索主要利用嗅觉，他们可能也有利於粗木质残体在森林地面上寻找附近地上提示松露位置。另外，由於内华达松露果显著的位置，在1996年取得了82％的松露再次以下2年， mycophagous北部鼯鼠一样的动物可能会受益记忆挂果位置和觅食每年在这些相同的位置。
