摘要:托福阅读背景知识:栖息地选择

在2014年5月17日的托福阅读考試中有那样一道题:栖息地挑选。对于这道托福考题,朗阁张俊聪教师来为我们推广一下有关栖息地挑选的情况专业知识,那样有利于学生在面临这类题型时便捷做答,朗阁张俊聪教师强调:动物个人行为主题是托福阅读普遍考试点,构造不难理解。特别注意各例子和主题的支撑点关联。   托福阅读考试真题重现:   版本一:一个叫Sale的生物学家汇总汇总出了栖息地的探寻和挑选是由于多种多样cue综合性产生一个应激起应,他否认了原有策略的观点。举了一个鱼种试验的事例,随后还*及这类观点匪夷所思为什么一种鸟会依据日照时数来挑选栖息地,*终说这类方式现阶段再有待科学研究。   版本二: 第三篇讲动物靠哪些挑选栖息地 某基础理论说 动物认知人体器官搜集信息内容随后意见反馈中枢神经系统 后又说别的基础理论一个是找大量食材,另一个因素是避开被觅食,*终说还必须进一步科学研究哪些真真正正危害,更关键点记了不得…   版本三:第三篇是挑选栖息地。说有些是到suitable的地点就停住,有些是先有mind随后再找什么的。别的的忘记了〒_〒   分析:文中紧紧围绕动物如何选择栖息地这一主题进行论述。刷题时特别注意纪录手记,针对结构型阅读文章及*终一题的解释有非常大益处。动物个人行为主题是托福阅读普遍考试点,构造不难理解。特别注意各例子和主题的支撑点关联。因为条理清楚,*终一题尽可能考虑到从正脸挑选出,清除辅助。   托福阅读有关环境:   Habitat selection   Habitat selection is the process or behavior that an animal uses to select or choose a habitat in which to live; correspondingly, plants and fungi engage in habitat selection, even though their inherent mobility is different from animals. To live in a habitat an animal must first have access to the habitat. Once the animal has access to the habitat it must be able to tolerate the conditions of the habitat and find the resources that it needs to survive in that habitat. Animals must be able to tolerate at least two kinds of factors in the habitat. These factors are abiotic factors and biotic factors. Abiotic factors are non-biological factors such astemperature, humidity, salinity and pH to name a few. Biotic factors are biological factors such ascompetition, predation, and disease. If both abiotic and biotic factors can be tolerated the animal must also be able to find the resources that it needs to survive. These resources include food, shelter from abiotic and biotic factors, and a mate. If an animal can not tolerate abiotic and biotic factors in a habitat or if it does not find food, shelter or a mate in that habitat, it is likely that the habitat will not be selected and the animal will leave the habitat. Habitats that are suitable for animals will often times have many animals of the same species there. This can lead to intraspecific competition. All of these things have an impact on the ecology of the animal (its distribution and abundance).   One way to determine if a habitat is suitable for an animal is to conduct a transplant experiment. In a transplant experiment animals of interest are transplanted or brought to a habitat to test that habitat for suitability. If the animal survives and reproduces in the habitat, it is concluded that the habitat was unoccupied because the animal was unable to get there or because it did not have access to the habitat. If the animal does not stay, survive, or reproduce in the habitat, it is concluded that it could be due to a lack of resources or because certain biotic and or abiotic factors are present and it can not tolerate them. A habitat that is suitable can become unsuitable if the animal's resources and or biotic and abitoic factors change. This is what often happens when we develop areas that are currently undeveloped. This causes us to see animals that we never saw in our environments before. It also can lead to a decline in the number of these animals.
