ABSTRACT By the use of CMR technique, this activity aims to estimate a population size in a given area in a simple manner. In this method in which a sample is captured, marked, and released and the proportion of marked individuals to unmarked in a later sample is used to estimate total populations. The activity was conducted just in inside our classroom at s14 CNSM building. After this activity we are able to appreciate how MCR technique works.
INTRODUCTION
A population maybe defines as a group of organisms of the same species occupying a given area at a particular time. The population has group properties which are statistical measures that cannot be applied to individuals. The first and most basic characteristics of the population that ecologies are very much interested in is its density or size. It is defined as a number of individuals the status of a population. Four processes – natality, mortality, immigration, and emigration interact together to determine the population size. Since it is rarely possible to count all the individuals in an area (especially large ones), ecologies are usually content to count only a small fraction of population and to use this sample to estimate the total. Two of the most commonly used methods of sampling population to estimate its size are quadrant sampling and the capture-mark-recarpture method. The present exercise will focus only the latter. Quadrat sampling will be explored in the exercise on quantitative estimation of vegetation. Odum (1970) describes the CMR techniques as the “method in
