A1 WHAT IS ECOLOGY? Key Notes a definition of Ecology is the study of the interactions between ecology organisms and their environment. The environment'is a combination of the physical environment(temperature water availability, etc )and any influences on an organism exerted by other organisms-the biotic environment

个休、种群、群 生态学所研究的有4个可辨别尺度的亚部分:(i)探讨 落和生态系统 个体对其环境的反应;(1)研究单个物种的种群对于 环境的反应,和探讨诸如多度( abundance)及其波动 等的过程;(ⅲ)群落(出现在确定面积中的种群集 合)的组成和结构;(ⅳ)生态系统(群落与环境的非 生物成分的结合)内的各种过程,例如能流、食物 网和营养物的循环等

A2生态学的10个规律 要点 这些规律是什么? 生态学的授课实践使得本书作者能够觉察到大学生学 习生态学时常常陷入的某些一般性错误。本目录是为 克服这些错误而设计的,既不全面,也不互相排斥 但是我们希望它将作为有用的指南。 规律1:生态学 生态学是一门纯科学学科,目标是了解有机体与其广 是科学 阔环境的相互关系。分清楚科学观点与生态学知识的 政治和社会影响这一件事是十分重要的

A2 TEN RULES IN ECOLOGY? Key notes What are these rules? The authors experience of teaching ecology has given them experience of some common pitfalls which ecology students often make. This list, designed to counter these pitfalls, is neither comprehensive nor mutually exclusive, but we hope will nevertheless serve as a useful guide to protocol Rule 1 Ecology is a science. Ecology is a purely scientific discipline which aims to understand the relationships between organisms and their wider environment. It is important to segregate political and social impacts of ecological understanding from the scientific viewpoint

Rule 2 Ecology is only understandable in the light of evolution. The huge diversity of organisms, and the wealth of variety in their morphologies, physiologies and behavior are all the result of many millions of years of evolution. Thos evolutionary history has left an indelible impression on each and every individual. It is only possible to make sense of the patterns we find today in the light of this evolutionary legacy Rule 3 Nothing happens'for the good of the sp A very common misconception is the idea that patterns of behavior in organisms which appear to be costly to an individual occur for the good of the species. This is absolutely and completely wrong. Natural selection will favor those genes which are passed on to the most offspring even if these genes may cause a reduction in the species population size

规律4:基因和有机体自己所处的环境,对于它在开放的各种选择中 环境都很重要决定取舍上,具有重要的作用。决定有权体构造的基 因,同样具有根本的重要性。这两方面因素的基本性 质及其相互作用,对于理解生态学都是很重要的。 规律5:理解复 生态学是一复杂的对象,几乎每一个尺度都有大量变 杂性要求模型异—亿万个种,每种有大量基因变异,在复杂和动 态的环境中有变化着的数量和随时间而改变的行为。 为了理解它,必需清楚的认明特异问题,然后形成可 以检验的假设。以数学的思想方法构造假说常常是很 有用的,可以躲开在语言模型中不能避免的含糊不 和混淆。数学模型在生态学里被广泛的应用

Rule 4 Genes and environment are both important The environment an organism finds itself in plays an important role in determining the options open to that individual. The genes which define an organism's makeup are also of fundamental importance. To understand ecology it is important to appreciate the fundamental nature of both of these factors and the fact that they interact Rule 5 Understanding complexity requires models. Ecology is a complex subject, with huge variation at almost every scale-millions of species, each with considerable genetic variation, varying numbers and ever-changing behaviors in a complex and dynamIc environment. To understand it, it is necessary to clearly identify specific questions and then formulate hypotheses which can be tested. It is often very useful to frame the hypothesis in mathematical terms to avoid ambiguity and confusion which are often inevitable in a verbal model Mathematical models are widely used in ecology
