有关动物论文

文章一狼属于犬科动物,狼机警、多疑,形态与狗很相似,只是眼较斜,口稍宽,尾巴较短且从不卷起并垂在后肢间,耳朵竖立不曲,有尖锐的犬齿,狼的视觉、嗅觉和听觉十分灵敏 古的人们: 把狼的形象画在石壁上时,心中充溢着惊奇;爱斯基摩人和印第安人很早就认识到狼的优秀特质,许多印地安部落还把狼选作他们的图腾,他们尊重狼的勇气、智慧和惊人的技能,他们珍视狼的存在,甚至认为在地球上,除了猎枪、毒药和陷阱,狼几乎可以和一切抗衡。 它具有超常的速度、精力和能量,有丰富的嚎叫信息和体态语言 , 还有非常发达的嗅觉;它们为了生活和生存而友好相处,为了哺育和教育后代而相互合作,其突出表现在群体社交和相互关心方面,可以说仅次于灵长目动物,因此它们的活动范围,伸展到山区、平原、沙漠、冻原……几乎遍及全世界!狼的历史比人类还长…… 从生态学上来说 : 狼可以控制草食动物的数量 , 也就是起着维护草原和森林生态平衡的作用 它们追捕的多是老、弱、病、残 , 对草食动物本身也起着复壮种群的作用 . 所以 , 在自然界中应该有狼 ; 没有狼 , 就不是一个完整的生态系统。文章二首先,人类对动物的肆意捕杀,一方面造成了动物的大量减少,另一方面也造成了动物对人类的敌意不断增强,一定程度上破坏了动物与人类的友好关系。事实上,一直以来,人类残害动物的行为一直没有停息过,吃孔雀、吃猫头鹰、吃猴脑、吃丹顶鹤、吸熊胆,真是到了“万物皆入口”的地步!您想,这样怎么能不引起动物的愤怒呢?怎么能让动物不挺身而出、奋起反击呢?这也是造成了动物攻击人类、甚至伤害人类生命的重要原因。 其次,随着人类社会的不断进步,人类自身的一些不良行为,不仅破坏了地球环境,也破坏到了动物的生存环境。工厂的污水、汽车的尾气、对森林的过度砍伐等不良行为,都对大自然造成了严重的破坏,同时也对生存在大自然的动物造成了直接的伤害,使动物生存艰难,种类、数量越来越少,破坏了整个生态系统的平衡,最终使人类走向灭亡。 可见,动物与人类的关系已经到了严重恶化的地步,同时,也威胁到了人类自身的生存。人类难道还能这样执迷不悟、不知悔改吗?!我想,人类应该及时改变自身的不良习惯,爱护动物,保护地球环境。 作为一名小学生,我们应该从我做起,从现在做起,爱护我们的大自然,保护我们周围的动物。 让我们大家一起行动起来,爱护动物,善待动物,成为动物的好朋友,为改善动物与人类的关系做出自己应有的贡献吧!

虐待动物、伤害动物的事件频频发生,对动物的保护问题引起社会的关注。对于这个话题你有什么想法吗?下面是我为大家整理的关于讨论保护动物的议论文,一起来看看吧!关于讨论保护动物的议论文篇1 佛教中倡导众生平等,然而,随着人类一天一天得壮大,人们的“花样”也越来越多了!几十年前,到处捕杀动物,以获取暴利:过了几年,又在餐桌上摆上了青蛙;这几年,又吃上了猫头鹰…… 人们对动物的“威胁”正逐渐增大,这也就有必要谈谈保护动物了。 保护动物是十分重要的。现代生物学一直强调大自然与人的协调发展。动物是大自然的一部分,因此人应当与动物和睦相处,应当保护好他们,否则,会遭到惩罚的。蝗灾,恐怖的两个字。当蝗虫成群结队之后,所到之处没有一片叶子,给人类造成了巨大的损失,为何?我想大家都明白。田鼠,粮食的另外一种天敌,当猫头鹰进入人的肚子里时,粮食也正进入田鼠的肚子里,日子久了,或许也会出现一个新的名词“鼠灾”,到时,人又吃什么呢?我想结果大家也知道。难道这些报复还不够么? 因此,我认为保护动物,尤其是对人类有益的动物,尤为重要!同时,保护动物也是一种责任。人类的责任! 在古时,中国可以说是名副其实的天然动物园,是动物的天堂!李太白的诗中曾这样写到“两岸猿声啼不住,轻舟已过万重山”,柳宗元也这样记载“潭中鱼可百许头”,醉翁先生也道出了“树林阴翳,鸣声上下”的热闹……类之记载数不胜数。但是,现在呢?河水清澈就实属不易,又怎么敢奢望“鱼可百许头”呢?再如,城市化夺走了动物们可爱的家园,动物园抢夺了动物们珍贵的自由,川流不息的汽车竟也夺走他们的生命……我无言以对,人们对动物的伤害太深了! 我们伤害了他们,难道现在保护他们不是我们的一种责任么? 既然保护动物是一种责任,是十分重要的,那么我们应该如何保护他们呢? 我认为,应当首先提高每个人保护动物的意识,可以设置相应的公益广告和标语,尤其是少年儿童,应从小加强这类教育。其次,我觉的应当设定相应的法律条文,法律是强有力的武器,只要抓到位,就一定能很好的制止这类现象的发生。 当然,这一切都离不开大家,只要每个人做到位,我相信,美好的阳光就会普照在无数生灵的心中! 关于讨论保护动物的议论文篇2 生活在同一个地球上,人与人之间应该相互关爱但决不能鄙视动物的生命,应该平等对待。 动物与人类是密不可分的,长久以来,人与动物就共存于一个大自然和同一个地球上,动物是人类的伙伴是人类的朋友,大自然是个平衡的生态系统,如果我们的伙伴消失了,人类也将不复存在。 目前很多动物都已灭绝:世界上最大的海确,毫无防御能力的史德拉海牛、地球上最大的狮子、生活最南端的狼、唯一生活在非洲的熊…… 面对这些残酷的现实,作为人类的我们难道没有一丝心痛?一份责任?动物是我们的朋友,这一点谁都知道,可是又有几个人轻易保护这些动物了呢? 我认为,每个人应该从实际出发,从小事做起,从自己,从身边做起。 曾经,世界上发生过无数疾病,害死了多少无辜的人,那些人都白白牺牲了,实际上大多数疾病传播都与动物有关,而这些动物也是非常无辜的,因为这些后果大多都是人为因素。 总之,保护动物是人类的义务! 关于讨论保护动物的议论文篇3 今天放学的时候,同学们正在教室里收拾书包,突然有一只小鸟飞进了教室。调皮王石亮看到了,便大声喊了起来:“大家快来看啊!有一只小鸟!”边说边跑过去把小鸟捉住了。大家都闻声而来,班长少文看到了,便对石亮说:“石亮,快把小鸟放了!别让小鸟难受。”石亮捉着小鸟,对少文说:“我为什么要听你的话,我捉住了就是我的,我要把它带回家饲养。”说着拿起书包就要往外走。刚好老师走进教室,石亮看到老师来了吓了一跳,赶紧把小鸟藏在身后。这时班长少文走到老师面前,向老师说明了情况后。老师走到石亮面前,说:“石亮,我们必须保护动物,如果人人都像你一样,看到了动物就捉起来,视为己有的话,那么世界上的动物,不就都没有了吗?”石亮听完老师的话后,惭愧极了,于是当众把小鸟放了,得到了老师的夸奖。从这件事中使我了解小学生还必须多认识保护小动物的知识。学校必须注重小学生对保护动物的认识,多教小学生一些关于保护动物的小知识。我相信只要这样做,不久人和动物一定能够和睦相处。 如果你是一只动物,却遭到了人类的猎杀,你会怎么想,你愿意吗,你愿意被猎杀吗?你绝对不愿意,有些人说:“我又不是动物。”但你们有没有想过动物们会怎么想吗?现在人类大量捕杀动物,动物会甘心吗?不,不会,永远不会。它们不愿意死在人类手里。它们愿意被你们猎杀吗?不,它们有一千个不愿意,一万个不愿意,一亿个不愿意…… 有些人虽然知道怎样去爱护动物,可是他们只会假惺惺地去教育别人,而自己却照样破坏环境,照样兴致勃勃品尝野味。 就拿印度洋毛里求斯群岛上生活的渡渡鸟来说,由于它身上的肉鲜美无比,所以遭到当时人类的大量捕食,在十七世纪就已告灭绝。但是如果当时人们有动物保护意识的话,就不会造成渡渡鸟的灭绝。 还有鲸,鲸不是让你们随意捕杀的,鲸是被杀掉一头就死一头的,不像小鱼小虾那样多,如果我们把鲸杀掉了,那我们的子孙后代,他们不是看不到鲸这种动物吗? 现在,有些动物已经灭绝了,鳄鱼虽然凶猛,但人类更凶猛。就是因为有些动物身上的器官具有突出的经济价值,由此成为被人类掠夺利用的对象,成为动物灭绝的主要因素。鳄鱼长着锐利的牙齿,和硕大的食物胃口,我们都说鳄鱼可怕,但鳄鱼更怕人类,在人类的眼中,鳄鱼皮可以制成行李箱,手提包,钱包,鞋等物品,所以鳄鱼,现在已经成为快要灭绝的动物了。 《金色的脚印》,这篇文章讲了正太郎家捉来了一只小狐狸,两只老狐狸想尽办法就救出小狐狸,正太郎很同情小狐狸,他偷偷地给老狐狸投送食物,于是,他们之间建立了亲密,信任的关系,后来两只老狐狸救了正太郎,最后,小狐狸回归了大自然,两只老狐狸是多么高兴!这篇文章赞美了人与动物之间互相信任,互相帮助,和谐相处的美好关系,也展现了动物之间的浓浓亲情。我们就要向正太郎学习,他帮助动物,动物也救了他,这样不是很好么?为什么人们还是要捕杀动物呢? 在此,我呼吁人们,不要再破坏自然界中的花草树木,不要再乱杀一禽一兽,不要再杀害我们的朋友,要保护好自然界中的一个个生灵。消灭动物,就是在消灭人类自己。如果有一天世界上的动物全都消失了,那人类还能生存吗?要保护动物,珍惜这自然界里的每一个生灵吧。 猜你喜欢: 1. 保护动物高中作文 2. 以保护动物为话题的作文800字 3. 以保护动物为话题的作文 高中 4. 保护动物类的作文精选3篇 5. 三年级保护动物的作文示例5篇

小狗的警惕性非同寻常,它有一个特别灵敏的鼻子,能闻到3里以外东西的气息,吃食物时,它总要低下头闻一闻。它还有一双耳朵,每当听到特别的声音,它的耳朵总会竖起来,认真地倾听着外面的动静!因而,人们养它来看大门,它是人类的忠实的朋友。 小狗有一张宽而大的嘴巴,嘴里有一排洁白而又锋利的牙齿,它一口就可以将一只大老鼠咬死! 小狗的眼睛不很好,大约只能看一里的距离。那么,它为什么能看准东西呢?它主要靠得是它的鼻子。 小狗的爪子很锋利,不用多长时间,它就可以挖一个很大的圆形的坑。 小狗刚生下来的时候,毛是棕色的,可是它长大以后就不再是棕色的了,而变成了深黄色。 小狗的性格非常温和。如果你对它好,它就会用头顶你的腿,好像是在向你撒娇;可是如果是陌生人来到它的家里,它仍会“汪汪”地叫个不停,甚至会扑到你身上咬伤你的。 夏天到了,大热天,我们常常可以看见狗总是在吐舌头,而不见狗出汗呢?原因很简单,那是因为狗的汗孔长在舌头上。 小狗真不愧为人们所喜爱,这是它用自己真正的本领换来的

陆地环境与水域环境相比,要复杂得多。 陆地气候相对干燥,与此相适应,陆生动物一般都有防止水分散失的结构。 陆地上的动物不受水的浮力作用,一般都具有支持躯体和运动的器官,用于爬行、行走、跳跃、奔跑、攀援等多种运动方式,以便觅食和避敌。 除蚯蚓等动物外,陆地生活的动物一般都具有能在空气中呼吸的,位于身体内部的各种呼吸器官。 陆地动物还普遍具有发达的感觉器官和神经系统,能够对多变的环境及时做出反应。 生活在陆地上的环节动物,如蚯蚓,生活在富含腐殖质的湿润的土囊中,通过肌肉和刚毛的配合使身体蠕动,以植物的枯叶,朽根和其他有机物为食。身体分节可以使蚯蚓的躯体运动灵活。它没有肺与气管,呼吸要靠能分泌黏液、始终保持湿润的体壁来完成。蚯蚓的体壁密布毛细血管,空气中的氧气先溶解在体表黏液里,然后渗进体壁,再进入体壁的毛细血管中。体内的二氧化碳也经体壁的毛细血管由体表排出。动物生活需要适宜的温度,蚯蚓不能保持恒定的体温,因此只能生活在温度变化不太大的土囊深层。 陆地动物还有哺乳动物。它们体毛光滑柔软,有保温作用;用肺呼吸;心脏分成四个腔,有2条循环途径;体温恒定;有门齿、臼齿,还有犬齿;有发达的脑神经与四肢。 陆生动物还有很多很多。但任何生物的形态结构生理功能与它们的生活环境适应。

有关动物学的论文

动物行为学的形成与发展 贾秀英 20世纪60年代以来,动物行为学的研究就受到各国科学家的关注。欧洲的一些动物行为学家对动物行为研究的发展作出了重大的贡献。70年代以来,随着人们对动物行为研究重要性的认识,有关的科研项目日益增多,动物行为学已成为生物学中极为活跃和重要的一个分支学科。它除了研究动物行为本身外,还把研究内容从行为维系群体的作用,扩展到行为的个体发育进化史、行为的控制及社会性组织等方面。通过这些研究,使动物行为学得到了进一步的发展,并已逐渐发展为一门不仅涉及行为学,而且涉及到生态学、生理学、心理学、遗传学、进化论、社会学和经济学的一门综合性学科。一、动物行为学的研究历史20世纪以前是动物行为学的萌芽时期,是动物行为学经历的一个缓慢发展的阶段。早在旧石器时代(34000~10500年前),人们开始注意观察周围的动物,随着动物家养的开始,人类也需要了解动物的生活周期和行为。在文明时代的早期,古埃及人开始尝试人工孵卵。古希腊的亚里斯多德(384~322BC)开始了观察、描述动物行为的新纪元。在他的论著中,记录了540种动物的生活史和行为,对后人关于生命的认识方面产生了相当大的影响。17、18世纪,研究动物行为的人更多了,开始了比较不同物种行为的研究和行为的理论探讨。如德国人约翰(Johunn Pernaller)研究了不同鸟的行为差异,涉及取食地、社会行为、筑巢、领地、季节性羽毛色彩变化、迁徙、鸣叫和育雏等方面。法国的勒雷(Chorles George Lereg)对狼、狐的捕食行为及野兔的恐惧表现有过生动的描述,提出了动物依靠它们的记忆和生活经验能够聪明地生活。1859年,达尔文的《物种起源》的发表,对动物行为学的研究产生了深远的影响。他的《人类的由来》(1871)一书研究比较了人与动物,及本能行为。19世纪末,人们使用述宫,研究老鼠的学习行为。劳埃德(C.Lioyd MOrgun)研究鸡的本能、学习、模拟行为。现代行为学中许多术语,如Behaviour(行为)、Animod Behaviour(动物行为),都首次出现在他的论著中。20世纪是动物行为学迅速发展和真正延伸的世纪。霍布豪斯(Hobhouse)在1901年发现了猴及其它动物能使用一定的工具(棍、箱子)得到食物。1906年,动物学家詹宁斯(H.S.Jennings)对原生动物的行为进行了详细研究,写出了《原生动物的行为》一书,这是第一本专门论述动物行为的著作。柏林的海因罗特(Oskar Heinorth)在1871年至1945年间,详尽研究了多种鸭、鹅,比较了它们的运动方式、解剖学特征、社会行为、鸣叫及繁殖行为,并且发现了灰雁从孵卵箱中孵出后的印记行为。他独自阐述的同源性学说,现在还被许多人认为是行为学真正诞生的标志之一。动物学家罗曼内斯(H.S Reimarus)发展了达尔文的思想,并正式建立了比较行为学这一学科,为现代的行为生物学奠定了基础。随后摩尔根(C.L.Morgun)和杰姆斯(W.James),以及劳埃波(J.Loeb)等都在方法、概念上对行为的发展做出了贡献。 1931年至1941年,欧洲著名的行为生物学家廷伯根和劳伦兹在自然和半自然条件下对动物进行了长期的观察,发表了诸如“社会性鸦的行为学”、“鸟类环境世界中的伙伴”、“关于本能的概念”、“对雁鸭类行为的比较研究”等论文,建立了物种的行为图谱,发现了所研究的行为型的功能。提出了显示、位移、仪式化等等新概念和新的研究课题。特别是劳伦兹提出的“印记”这一术语,极好地说明了先天性和后天获得性行为的结合问题。在行为分析、行为生态方面作出了很大的贡献。二、动物行为学的现代进展近年来,动物行为学的研究获得了蓬勃的发展,主要是把动物行为与生命科学中许多其它的许多分支学科相互渗透在一起,形成了许多新的研究领域,从不同的角度进一步完整、系统地阐述动物行为的原因、机制、发生或发育。进化与适应功能等问题。动物行为学的分支很多,不可能在此全面论述,本文仅以行为遗传学和行为生态学为中心,作一简要介绍。1.行为遗传学 行为遗传学是用遗传学方法研究行为的遗传基础。自1960年,美国学者Thompson第一个总结了有关资料,写成《行为遗传学》一书,从而宣布这一新学科的诞生。其后,相关研究大量涌现。10年以后,一份专业期刊,《行为遗传学》问世。1967年,Benzer第一个通过人工诱导和选择的方法得到了果蝇的行为突变体,从而为行为遗传学的研究开辟了道路。从此以后,行为突变体的研究很快在果蝇、线虫、草履虫、细菌及其他生物的研究中大量开展起来。目前,已在分子水平分析的基础上,进一步作行为基因的分离、克隆和转移的研究。行为遗传学为动物行为学的研究开辟了一个新天地,对于阐明行为遗传的规律和机制都具有重要意义。2.行为生态学行为生态学主要是研究生态学中的行为机制、动物行为的生态学意义和进化意义,在理论及方法论方面是动物行为学中发展最快、最为活跃的一个领域。行为生态学主要涉及到取食行为生态学。防御行为生态学、繁殖行为生态学、社会生态学、时空行为生态学(如栖息地的选择、定向和导航、巢域和领域现象等),以及行为生态学预测等内容。其中,在社会生态学或社会生物学方面,近年来取得了突出的进展。K.Lorenz对鸟类社会行为的研究、N.Tinbergen(1974)对人类社会行为的研究,以及K.Von Frisch对蜜蜂社会行为的研究,奠定了社会生物学的基础。1975年,E.O Wilson出版了《社会生物学》一书,系统地介绍了这门学科的观点、理论体系和研究方法。社会生物学把达尔文自然选择的概念应用于社会行为的研究,又把生态学、行为学、遗传学和进化沦加以综合,提出了内在适合度和亲缘选择的新概念。这些新概念把社会行为的研究提高到了一个新的高度。目前,这一领域所展示的迷人前景正吸引着越来越多的科学家。尤其是关于行为经济学和进化稳定对策(ESS)的研究,正显示着强大的生命力。尽管在我国这一领域还几乎是个空白,但随着这一学科的迅猛发展,也必将引起我国学术界的巨大兴趣。动物行为的研究在我国正处于起步阶段,研究的内容主要是描述性的,在理论研究方面,在研究的广度和深度方面,与国外存在着很大的差距。到目前为止,国内仍没有形成专门的动物行为学教材、期刊。但据已公开发表的有关论文和资料显示,我国在动物行为某些领域方面的研究已取得了一定的进展。

1、 在中小学课外科技活动,对生物学科的某一专题是某一现象进行探索研究,把研究过程中枢观察纪录的资料,加工整理,综合分析,去会有共,并指出自己的观点。把上述的工作用文字系统全面的表达出来,这就是生物科学小论文。 2、 学生论文的特点 课题应具体,题目不应过大。因为基础知识薄弱,研究深度浅。生物科技小论文是学生进行生物科技活动的总结,这对扩大学生知识领域、培养能力、发展创造力,都有重要的实践意义。 完成生物小论文课题的方法 小论文课题确定后,怎样去完成研究课题呢?下面分别作些介绍。 (一) 考察法 即调查某一区域内的某些生物种类组成、数目和分布的规性等。如某的去昆虫种类及数目变化;环境宝物种的各种动物吹气候变化的调变,等等。 这种研究犯法化钱少,不需要复杂的仪器和设备一般的中小学都可进行。但指导教师事前应适当扑导,让学生与县长掌握一定的动物分类知识,并且事先订好固定的考察计划。 (二) 观察法:就是对某种动植物的个体进行仔细的观察,以了解掌握其生活习性和生长发育的规定性。佩观察的对象必须要有一定的数目,因为只对一个个体进行观察,其必然性的因素太大,回引响研究的结论。观察的同时,应随时注意收集实物资料,使证据更完全,效果更好。 (三) 实验法 在人物改变某个环境因素条件下(如营养、温度、光照等),观察在某一特定环境下,环境对生物产生的引响,找出其中的规定性的研究方法。注意点:1:要有对照组 2:研究的对象要有一定的数目。 例:"营养对青蛙蝌蚪发育的影响"。 实验时,分天然水和坦然谁加少是农家肥,两族作对照。试验过程中,除了营养条件不同外,其他条件如蝌蚪的来源、大小、水温、光照等都要尽权,一免其他因素影响了实验。 以上三种方法在实验研究中常有的,以那一中为止,以课题内容、性质而定。但不要用那种方法,都要引导学生进行仔细的观察,特别是在变化过程,要做好计数和测量,记录下来,然后用统计学得出正确的结论

动物行为学论文

动物行为学的形成与发展

一、摘要

20世纪60年代以来,动物行为学的研究就受到各国科学家的关注。欧洲的一些动物行为学家对动物行为研究的发展做出了重大的贡献。随着人们对动物行为研究重要性的认识,动物行为学已成为生物学中极为活跃和重要的一个分支学科。它除了研究动物行为本身外,还把研究内容从行为维系群体的作用,扩展到行为的个体发育进化史、行为的控制及社会性组织等方面。

二、动物行为学的研究历史20世纪以前是动物行为学的萌芽时期,是动物行为学经历的一个缓慢发展的阶段。早在旧石器时代(34000~10500年前),人们开始注意观察周围的动物,随着动物家养的开始,人类也需要了解动物的生活周期和行为。

1、在文明时代的早期,古埃及人开始尝试人工孵卵。古希腊的亚里斯多德(384~322BC)开始了观察、描述动物行为的新纪元。在他的论著中,记录了540种动物的生活史和行为,对后人关于生命的认识方面产生了相当大的影响。

2、17、18世纪,开始了比较不同物种行为的研究和行为的理论探讨。如德国人约翰(Johunn Pernaller)研究了不同鸟的行为差异,涉及取食地、社会行为、筑巢、领地、季节性羽毛色彩变化、迁徙、鸣叫和育雏等方面。法国的勒雷(Chorles George Lereg)对狼、狐的捕食行为及野兔的恐惧表现有过生动的描述,提出了动物依靠它们的记忆和生活经验能够聪明地生活。

3、1859年,达尔文的《物种起源》的发表,对动物行为学的研究产生了深远的影响。他的《人类的由来》(1871)一书研究比较了人与动物,及本能行为。19世纪末,人们使用述宫,研究老鼠的学习行为。现代行为学中许多术语,如Behaviour(行为)、Animod Behaviour(动物行为),都首次出现在他的论著中。20世纪是动物行为学迅速发展和真正延伸的世纪。

4、1906年,动物学家詹宁斯(H.S.Jennings)对原生动物的行为进行了详细研究,写出了《原生动物的行为》一书,这是第一本专门论述动物行为的著作。柏林的海因罗特(Oskar Heinorth)在1871年至1945年间,详尽研究了多种鸭、鹅,比较了它们的运动方式、解剖学特征、社会行为、鸣叫及繁殖行为,并且发现了灰雁从孵卵箱中孵出后的印记行为。他

5、动物学家罗曼内斯(H.S Reimarus)发展了达尔文的思想,并正式建立了比较行为学这一学科,为现代的行为生物学奠定了基础。随后摩尔根(C.L.Morgun)和杰姆斯(W.James),以及劳埃波(J.Loeb)等都在方法、概念上对行为的发展做出了贡献。

6、1931年至1941年,欧洲著名的行为生物学家廷伯根和劳伦兹在自然和半自然条件下对动物进行了长期的观察,发表了诸如“社会性鸦的行为学”、“鸟类环境世界中的伙伴”、“关于本能的概念”、“对雁鸭类行为的比较研究”等论文,建立了物种的行为图谱,发现了所研究的行为型的功能。提出了显示、位移、仪式化等等新概念和新的研究课题。

三、动物行为学的现代进展

1、近年来,动物行为学的研究获得了蓬勃的发展,主要是把动物行为与生命科学中许多其它的许多分支学科相互渗透在一起,形成了许多新的研究领域,从不同的角度进一步完整、系统地阐述动物行为的原因、机制、发生或发育。进化与适应功能等问题。动物行为学的分支很多,本文仅以行为遗传学和行为生态学为中心,作一简要介绍。

2、行为遗传学 行为遗传学是用遗传学方法研究行为的遗传基础。自1960年,美国学者hompson第一个总结了有关资料,写成《行为遗传学》一书,从而宣布这一新学科的诞生。其后,相关研究大量涌现。10年以后,一份专业期刊,《行为遗传学》问世。

3、1967年,Benzer第一个通过人工诱导和选择的方法得到了果蝇的行为突变体,从而为行为遗传学的研究开辟了道路。从此以后,行为突变体的研究很快在果蝇、线虫、草履虫、细菌及其他生物的研究中大量开展起来。目前,已在分子水平分析的基础上,进一步做行为基因的分离、克隆和转移的研究。

4、行为生态学行为生态学主要是研究生态学中的行为机制、动物行为的生态学意义和进化意义,在理论及方法论方面是动物行为学中发展最快、最为活跃的一个领域。行为生态学主要涉及到取食行为生态学。防御行为生态学、繁殖行为生态学、社会生态学、时空行为生态学(如栖息地的选择、定向和导航、巢域和领域现象等),以及行为生态学预测等内容。

5、1975年,E.O Wilson出版了《社会生物学》一书,系统地介绍了这门学科的观点、理论体系和研究方法。社会生物学把达尔文自然选择的概念应用于社会行为的研究,又把生态学、行为学、遗传学和进化沦加以综合,提出了内在适合度和亲缘选择的新概念。

6、这些新概念把社会行为的研究提高到了新的高度。目前,这一领域所展示的迷人前景正吸引着越来越多的科学家。尤其是关于行为经济学和进化稳定对策(ESS)的研究,正显示着强大的生命力。尽管在我国这一领域还几乎是个空白,但随着这一学科的迅猛发展,也必将引起我国学术界的巨大兴趣。

7、动物行为的研究在我国正处于起步阶段,研究的内容主要是描述性的,在理论研究方面,在研究的广度和深度方面,与国外存在着很大的差距。到目前为止,国内仍没有形成专门的动物行为学教材、期刊。

Dogs belong to the canine.

When a dog follows its nose, it's actually being led by thee key senses. Sight:a glimpse of the enemy saves them barking up the wrong tree. Sound: a bark can be a fierce threat, but it's also how canines make their long distance calls. Smell: this tells a dog more than all the other senses put together.

Inside its nose are around two hundred million smell sensitive cells, forty times more than in humans. Through them the dog's brain can pick up signals from one molecule of scent in a million. It gives the dog: a completely different picture of the world, based on what it smells, rather than what it sees.

Flowers are irrelevant to a dog. So their scent is meaningless. But food is a serious matter. What to us is an empty plate, is covered with the smell of chicken to a hungry dog.

狗属于犬科劝物.

当狗用鼻子嗅着前行时,实际上有三种感觉在起作用:视觉,瞥一眼就知道敌人在哪儿;听觉,犬吠有一种凶猛的威慑力,这也是犬科动物闽相互嗅寻的方式;嗅觉,能给狗提供的信息比其他感觉总和还多.

狗的鼻孔大约有2亿左右的嗅觉细胞——比人多40倍.通过这些细胞,它的大脑能从100万个气体分子中筛选出1个.根据所闻而不是所见的东西,展现给狗的是一个完全不同的画面.

花对狗来讲无足轻重,所以花香对狗无关紧要.可食物是件大事,对我们来说是一个空盘子,可对一只饥肠辘辘的狗来说却散发着鸡肉的香味.

我家有一只纯正的金毛,名叫金毛。正如其名,它全身都是如上等丝绸般的毛发,双眼乌黑清澈,四肢健壮有力。每一次我一回家,它就张开那四肢,飞快地向我奔来,扑在我的身上,用粉红略微粗糙的舌头来舔我的脸颊,可爱得像孩童。

一次,我写完作业,放起摇滚乐放松一下。谁知,金毛跑来,趴在我的身边,一边闭眼听着乐曲,一边还随着音乐的节奏把尾巴摇来摇去,憨态可掬的样子真是让人忍俊不禁。

一天,妈妈在客厅织毛衣,一不小心,毛线团滚到了地上,金毛耳朵一动,闪电般地冲过来,灵活的大眼机灵地转来转去,寻找毛线团。突然,身子一跃,前爪把毛线团紧紧地按在地上,快活地玩了起来:它一会跳过来,一会蹦过去,还有前爪拍打毛线团,像小孩子玩皮球。无不透露着它天性珠顽皮。

金毛特别爱吃鸡肉,一回,我趁妈妈做口味鸡时,拿了一块闻着就让人食欲大开的鸡肉,然后拿出一概细长的竹条,一头系着细线,细线系着鸡肉,我要去逗逗我的金毛。

我把鸡肉在金毛眼前晃来晃去,诱人的香味一会在一会右,勾得金毛晕头转向。大眼跟着鸡肉一起转来转去,我忽然停止摇晃,金毛立刻缓过神来,向上扑来,我把竹条再向上一抬,就让金毛扑了个空。我嘿嘿笑了两声,金毛似乎生气了,汪汪汪连着叫了好几声,又像央求我给它东西吃似的。我才不上你这个当哩!我把竹条放低了些,金毛见状,哪能能错过这大好的机会,它又扑了上来,我把竹条一绕,绕到了金毛的身后,金毛把身子一扭,却够不到了。

如此几回合下来,金毛垂下脸袋,似乎在为抢不到食物面沮丧。我正准备伸手去安慰它时,谁料,它竟猛地抢过鸡肉,一口吞下了肚。

我气愤极了,转身不理它,金毛见我这样,计好地钻进我的怀里,用金色的小脑袋蹭着我的肩,仿佛一个可爱的小孩子在向我撒娇。我的心一动,但坚持不理它,金毛便宜继续蹭着我,用可怜巴巴的眼望着我。而我,一时没有忍住,“噗”地笑出声,金毛见我笑起来,也高兴地叫了两声,金色的尾巴摇来摇去,用舌头舔着我的脸,我们一人一犬又和好了。

我爱我的金毛!

我喜爱的小动物很多,珍禽异兽无所不爱,但在这数不胜数的小动物里,最令我爱不释手的.还是我家的小仓鼠。

我家有一只小仓鼠,我给它取名为“阿娄”。阿娄长着一副可爱的小脸蛋,红彤彤的,看了就令人魂不守舍的爱上它。它还有一双黑宝石般的大眼睛,活像夜里的猫头鹰。最令人着迷的还是它那雪白的绒毛和那细长的小爪爪,那绒毛摸起来手感适佳,舒服极了。它那小爪爪是最令人揪心的,小小的爪子,动来动去可爱极了!

记得有一次我把小仓鼠放到一个盆里,让它游泳,它一下水就开始了狗刨式游法,用它那小爪在水里不停地摆动,真别说老鼠竟会游泳,还有这么快,加油阿娄!你就是未来的田亮!慢慢的,小仓鼠适应了游泳,就开始了花样游泳。自由泳,蛙泳,看那动作,阿娄你就是为游泳而生的啊!惊人的来了,小仓鼠在水中纵身一跃,哇!蝶泳,“扑通”有掉进水底,太棒了!阿娄不仅会蝶泳,还会闷水,我果然没看错你!过了一会儿,阿娄怎么没浮上来?难道,不好!我用迅雷不及掩耳之速把阿娄捞了上来,一救上来,阿娄便吐了一口水,睁开了眼。我心想这小仓鼠,说它游泳厉害,就骄傲自大还闷水,再怎么说你也还只是只老鼠呀!

发生在我和阿娄身上的趣事可不止这些!有一次,我的好朋友张艺潇带着它的小黑鼠“黑豆”来我家找我玩,来到后,他突发奇想说:“要么让两只小仓鼠来一次‘男鼠’之间的摔跤比赛吧!”我一听还挺有趣,就毫不犹豫的答应了。比赛开始!张艺潇的黑豆迅速跑了过来,抱住阿娄用力一推,啊!阿娄被摔到在地,可阿娄不服输,又站了起来,但黑豆根本不给我家阿娄一个喘气的时间,又用爪子抓住了阿娄,就这样又是一个用力一摔,什么!阿娄顶住了!反而用爪子在黑豆脸上疯狂乱抓,黑豆倒下了,张艺潇大叫:“犯规了!这是摔跤比赛,不能用爪子!”我心想这老鼠又不是人,怎么知道摔跤规则吗,跟只老鼠计较根本不就是对牛弹琴吗?虽然阿娄犯规了,但我依然很欣慰,能把黑豆打倒就说明阿娄还是挺有实力的!

小阿娄,一只平凡的小仓鼠,但却是我一生的最爱,小阿娄,我爱你!
