新加坡国立大学生物学Essay代写:蝙蝠仿生原理

锤头蝙蝠是食果动物,这意味着它们的饮食完全由水果组成。虽然无花果是他们喜爱的食物,但他们也吃香蕉、芒果和番石榴。蝙蝠的肠子比一种食虫物种的肠子长,这使得蝙蝠能够从食物中吸收更多的蛋白质。关于蝙蝠吃鸡肉的报道,只有一篇,但尚未证实有肉食活动。蝙蝠被人类和猛禽捕食。它们也容易受到严重的寄生虫侵扰。锤头蝙蝠容易被螨和木质肝囊虫感染,木质肝囊虫是一种影响肝脏的原生动物。该物种是埃博拉病毒的可疑宿主,但截至2017年,在动物中只发现了针对该病毒的抗体(而不是病毒本身)。蝙蝠是否能将埃博拉病毒传染给人类尚不清楚。白天,蝙蝠栖息在树上,依靠它们的颜色来伪装它们免受捕食者的伤害。他们晚上摘水果吃。像锤头蝙蝠这样的大型蝙蝠夜间活动的一个原因是因为它们的身体在飞行时产生相当大的热量。夜间活动有助于防止动物过热。有些种群在旱季进行繁殖,有些种群在一年中的任何时间进行繁殖。蝙蝠的大多数成员通过LK交配繁殖。在这种交配方式中,雄性成群结队地聚集25到130个人进行交配仪式,包括拍打翅膀和大声鸣叫。女性通过小组评估潜在配偶。当雌性选择时,她就在雄性旁边,交配发生。在一些锤头蝙蝠种群中,雄性蝙蝠表演它们的表演来吸引雌性,但不形成群体。雌性通常生下一个后代。怀孕和断奶所需的时间还不清楚,但众所周知,女性比男性成熟得更快。女性在6个月时达到性成熟。雄性发育锤头脸需要整整一年的时间,大约需要18个月才能成熟。蝙蝠在野外的预期寿命为三十年。最后对锤击蝙蝠的保护现状进行了2016的评价。蝙蝠被归类为“最不担心的动物”。虽然蝙蝠被捕食为灌木肉,但是蝙蝠的地理分布范围很大,而且总体数量并没有急剧下降。

Hammerhead bats are fruit eaters, which means that their diet consists entirely of fruit. Although figs are their favorite food, they also eat bananas, mangoes and guavas. The intestines of bats are longer than those of an insectivorous species, which allows bats to absorb more protein from their food. There is only one report about bats eating chicken, but no meat activity has been confirmed. Bats are preyed on by humans and birds of prey. They are also vulnerable to severe parasite infestation. Hammerhead bats are susceptible to mites and lignocellular cysticercosis, a protozoan that affects the liver. The species is a suspected host of Ebola virus, but as of 2017, only antibodies against the virus (not the virus itself) had been found in animals. It is not clear whether bats can transmit Ebola virus to humans. During the day, bats inhabit trees and rely on their color to disguise themselves from predators. They pick fruit at night. One reason why large bats such as hammerhead bats are nocturnal is that their bodies generate considerable heat during flight. Night activities help prevent overheating in animals. Some populations reproduce in the dry season, and others reproduce at any time of the year. Most members of bats breed through LK mating. In this form of mating, males gather in groups of 25 to 130 people for mating rituals, including flapping their wings and making loud calls. Women assess potential spouses through groups. When a female chooses, she is next to the male and mating takes place. In some hammerhead bat populations, males perform their performances to attract females, but do not form groups. Females usually give birth to one offspring. The time required for pregnancy and weaning is unclear, but it is well known that women mature faster than men. Women reach sexual maturity at 6 months. Male development of hammerhead faces takes an entire year, and it takes about 18 months to mature. The life expectancy of bats in the wild is 30 years. Finally, the status quo of hammer bat protection was evaluated in 2016. Bats are classified as “the least worried animals”. Although bats are preyed on shrub meat, the geographical distribution of bats is very wide, and the total number of bats has not declined dramatically.
