请问巢穴的那篇是这个吗~
蚂蚁巢穴
※本月原始
V1
Ant Mound Question
Talks about how the strucutres of an ant mound and why it is such.. Provides two
contrasting views that explains why these strucutures exist. Author support the
2nd theory.
Q1)According to the first theory 名字忘记了, what is the purpoes of the tunnels?
Answer has something to do with air flow
Q2) If the passages were sealed, what would happen according to passage?
Answer deals with humidity
Q3) 暂时想不起来,过会儿补充
V2 by 大大尧
土著人在地下建特别的建筑,有复杂的内部结构,两种不同的理论讨论内部的温控,第一种
是说热空气通过 tunnels 上升冷却,再下来,这样循环。第二种是说里面是恒温的,气体交
换是维持内部空气的湿度稳定,还有空气成分稳定,这样里面有一种菌类可以生长。

有道讲 terminate mound 的 function 的
P1 在某建筑还是 nest 的地方发现一个烟囱一样的东西,有人说他是用来维持这个建筑的温
度的
第二段反驳,说是用来空气流通保持 humidity CO2 等
问主旨,选的 refute 一个然后提出一个 alternative 的
有道问如果这个 tm 的 passage 被 sealed 了会怎样,定位在第二段
※往届考古 已确认

好像是一种动物在巢穴的周围挖了一系列的小隧道,有一个人提出这些隧道是为了保持巢穴
恒温,第二段说前面的假说错误因为巢穴没有恒温,提出了一个假说是为了保持空气流通,
保持一定的湿度
V2 by foxwill
一种动物蚂蚁的巢穴,有一个中心(大概是 chamber),然后还有很多小隧道(形似 mound),
连接他们并通往地面高处。第一个人提出一种理论认为,这些小隧道是用来保持 chamber
温度的。巢穴里因为蚂蚁的新陈代谢,温度会不断上升。而被加热的温度 mound 挥发出去,
地面的降低温度又通过 mouth 补充进来,从而保持巢穴温度不会太高。
然而,第二个人发现保持温度的理论不对。这些 mound 的作用是保持空气流通的。因为他发
现这先 mound 的出口都在地面 XX 处(有一个合成词,什么 ground-level 啥玩意的,描述这个地面特点,我理解为高处通风处,具体的大家可以在考场上判读,不要受我误导)。巢穴
中的空气通过 mound 排出,新鲜空气中的氧气,二氧化碳和其他成分通过 mound 补充进来,
从而保证了巢穴内空气的流通(前面的同学说这段还提到了湿度,这个我记不清了,感觉好
象是选项里出现的未定位内容,待确定)。
然后举了个例子,说另外一种昆虫也有类似的巢穴结构,并且因此而具有强大的生命力。如
果这种昆虫没有这个巢穴结果,他们会被 surpressed,因为他们的竞争对手生命力比他们
更强。
题目都不难,找准定位就好。记得有道比较阴险的:
1)问:第一个人的理论关于 mound 的有:1)保持 mound 和 chamber 的温度一致(这是个陷
阱选项);(2)使得巢穴内空气与外界交换(这是正确选项,因为第一个人的描述,保持温
度也是通过气体交换实现的)。这题我比较确定我的答案,当时的定位比较清晰。
2)然后还有道好像是问关于第三段那个例子的,说例子昆虫和他的竞争对手咋样咋样,这
题读懂我上面说的应该就够了,忘记具体问啥了。
3)好像还有一道(不太确定)是问第一个人和第二个人理论的共通点?有这题的话肯定选
都是气体交换了,很明显。
4)然后好像还有一题是针对地面 XX 处那个合成词的,把这个词理解好了就能解题了。具体
问什么实在想不起来,有别的同学给提示一下的估计能想起来,呵呵。
v3 by gloria6113 Host age is one of the key factors in host–parasite relationships
as it possibly affects infestation levels, parasite-induced mortality of a host, and
parasite distribution among host individuals. We tested two alternative hypotheses
about infestation pattern and survival under parasitism in relation to host age. The
first hypothesis assumes that parasites are recruited faster than they die and, thus,
suggests that adult hosts will show higher infestation levels than juveniles because
the former have more time to accumulate parasites. The second hypothesis assumes that
parasites die faster than they are recruited and, thus, suggests that adults will
show lower infestation levels because of acquired immune response and/or the
mortality of heavily infested juveniles and, thus, selection for less infested adults.
As the negative effects of parasites on host are often intensity-dependent, we
expected that the age-related differences in infestation may be translated to lower
or higher survival under parasitism of adults, in the cases of the first and the second
hypotheses, respectively. Wemanipulated ectoparasite numbers using insecticide and
assessed the infestation pattern in adult and juvenile gerbils (Gerbillus andersoni)
in the Negev Desert.We found only a partial support for age-dependent parasitism.
No age-related differences in infestation and distribution among host individuals
were found after adjusting the ectoparasite numbers to the host’s surface area.
However,age-related differences in survival under parasitism were revealed.
The survival probability of parasitized juveniles decreased in about 48% compared to
unparasitized hosts while the survival probability of adults was not affected by
ectoparasites. Our results suggest that the effect of host age on host–parasite
dynamics may not explicitly be determined by age-dependent differences in
ectoparasite recruitment or mortality processes but may also be affected by other
host-related and parasite-related traits

是那个蚁穴 降温还是通风的。问题有一个是问 2 个理论的共同点 2. 第一个观点认为
下面那个是对的
V5 by wang_mm2000
寄生那篇文章,所 google 到的部分其实只是考试文章的第一段,后面还有很重要的一段没
有。而且有三道细节题出在第二段,其中有一道问如果 adult and juvenile have the same
surface area ,which of following will be true? 还有一道问 soil erosion,请大家定位
文章的最后一句话, 我就是没注意这个词,结果浪费了不少时间去找。汗。 |
