警戒

"These things happened unto them by way of example, and they were written for our admonition."

"他们遭遇这些事，都要作为监戒；并且写在经上，正是警戒我们这末世的人。"

Scientists on Wednesday raised the alert level for Anak Krakatoa and Tangkuban Prahu -- which regularly spew gas and rumble -- from "normal" to "warning," the middle of three alert levels.

上周三，科学家们将喀拉喀托火山和唐库班珀拉胡火山的警戒度由"正常"提高到"警告"，三级警戒的中间等级，因为这两座火山近来定期喷出火山灰，并发出隆隆的声音。

Pushed by Hamilton's theory, some botanists have discovered and testified aposematic coloration do exist in plants such as autumn leaves, young leaves of tropical rainforests, some thorny plants and reproductive organs of plants whereas some of them are still obscure or controversial.

起源于猎物－捕食者关系的警戒色理论在动物界得到了充分研究，但植物警戒色却不为人所知，直到2001年Hamilton关于秋季树叶颜色的信号假说公开发表后，才引起人们对植物警戒色的初步研究。

After sampling and avoidance learning, herbivores can discriminate this signal and associate it with unpleasant experiences, so aposematic coloration comes into being between plant-animal interaction. The theory of aposematic coloration has not been accepted in plants while it has been adequately discussed for a long time in animal kingdom until Hamilton's signal theory about autumn colours was published.

颜色作为一种稳定有效的视觉信号通常是花和果实的诱惑信号，某些情况下也是一种警戒防御信号，植食动物经过抽样学习后能识别这种防御信号并主动回避，从而形成了植物的警戒色。

Aposematic coloration should not only belong to animals, plants could evolve it too if necessary for plant fitness. The temporal and spatial colour polymorphism in vegetative parts of plants deserve more research and the defense tradeoff hypothesis predicts the possibility of aposematism may occur in the reproductive organs of plants.

如今在早秋变色树种、幼叶、多刺植物、植物繁殖器官都发现了警戒色的一些例证，尽管有些还不太明确甚至存在争议，但至少为植物警戒色的进一步研究奠定了基础。

Monacha at the foraging site had a certain time budget rhythm in the breeding period. In the prophase of breeding, the male and female moved together at the foraging site in the whole day; the main activities of the male were feeding, guarding, walking around, maintaining and wooing, while those of the female were feeding, guarding, walking round and maintaining. In the anaphase of breeding, there were two stages every day when the male and female did their own activities at the foraging site (4:00~6:00 and 17:00~19:00), neither the male nor female had wooing activity.

在繁殖前期，雌、雄白头鹤全天(5：30~18：00)成对在觅食地活动，雄性个体以取食、警戒、游走、保养和求偶为主要行为，雌性个体以取食、警戒、游走和保养为主要行为；到繁殖后期，雌、雄白头鹤每天有两个时间段单独在觅食地活动（4：00~6：00和17：00~19：00），无论雌雄个体，均无求偶行为。

So prohibiting human disturbance and stopping shallow water areas and grassland habitat destruction as well as recovering the original habitat are important measures to mitigate the conflicts between Ruddy Shelducks and local people.

取食的时候，雌性赤麻鸭的警戒水平随捉到其雄性配偶的距离的增加而显著增长，而雄性赤麻鸭的警戒水平并未随着到其雌性配偶的距离的改变而发生变化。

Scientists on Wednesday raised the alert level for Anak Krakatoa and Tangkuban Prahu -- which regularly spew gas and rumble -- from "normal" to "warning," the middle of three alert levels.

上周三，科学家们将喀拉喀托火山和唐库班珀拉胡火山的警戒度由&正常&提高到&警告&，三级警戒的中间等级，因为这两座火山近来定期喷出火山灰，并发出隆隆的声音。

Two-position models offer "Normal" and "Tagged" positions, while three-position models have "Closed,""Open," and "Tagged" positions.

这些紧凑的结合点有大量的触点并且有两三个点可利用，两点模型有&正常&和&警戒&状态，三点模型有&开&&关&&警戒&状态，最佳模型允许双向操作。

By the time of its fall, most of the prisoners were writers who had written against the corruptions of the government.

The most obvious variation to ovum morphological character was that the color was changed from light green to sepiaceous in embryonic development, and all the ovums were almost hatched after 96h.

在胚胎发育过程中卵的形态特征最明显的变化是颜色从淡绿到深褐色，卵在发育96h后卵基本全部孵化。
