What is the formula to calculate size of a sample?
by using the capture-recapture method which gives you the total size of organisms in a population.
How can an ecologist predict the size of a population without counting every organism in the population?
Through mark-and-recapture projects, direct observations, or targeted sampling, ecologists are able to determine the population of a particular species. This process is a scientific estimation of the population.
What are the various kind of sampling?
They include: Simple random sampling, Systematic sampling, Stratified sampling, Quota sampling, and Cluster sampling.
What are the sources of sampling errors?
Sampling and Non sampling errors
What sampling method?
Random Sampling
What are the steps in the mark and re-capture method in population sampling?
what are the steps involved in the mark and re-capture method in population sampling
What is the Name for recapture of Spain by Spain?
It's called "Reconquista". Capture of Aztec empire was conquista, so from this we have "conquistadors".

What are four methods of determining populations size?
what are four methods of determining populations size?
What is the name for recapture of Spain by christians?
It's called "Reconquista". Capture of Aztec empire was conquista, so from this we have "conquistadors".
What is the population of leafy seadragons?
leafy seadragons only live in south australia and the population counted with the capture/ recapture method is 1,527,400
How can an ecologist ecologist measure population size?
An ecologist can determine the size of a population without counting every organism by either sampling, mark-and-recapture studies, or indirect or direct observation.
What are the assumptions of mark recapture method?
The assumptions of the mark-recapture method include: 1) The population is closed (no immigration, emigration, or deaths) during the study period, 2) Marks do not affect the probability of capture, and 3) Marks are not lost or overlooked between captures.
What method of census taking would be best to monitor?
Census taking for sea horses is an impossible task. The best that you can hope for is a capture-recapture exercise.
Capture-recapture is a good way to estimate the population size of?
Deer and other animals that do not stay put. Squirrels, salmon, and butterflies are some other examples.
What are four ways to determining population size?
Sampling - counting the number of organisms in a small area and multiplying to estimate the number in a larger areaMark & Recapture - capture an organism & release it to remix with population. Then recapture some more in that area to determine population size. Formula is as follows: R (marked recaptures) / C (total in second sample) = M (marked initially) / N (total pop. size)Indirect Observation - estimating the population size by tracks, nest or other animal signs in an ecosystem.Direct Observation - count all members of a population in an ecosystem
What has the author Rajan Gupta written?
