Estimating Population Size
All monitoring programs are designed to detect change in population size. Some require, in addition, estimates of population size itself. Two approaches to making such estimates, using various m ark-recapture methods or removal sampling, are described in this chapter. Whatever the method, estimation of population size requires extensive data collection and analysis and is labor-intensive and ti...
متن کاملEstimating population size in emergencies.
One of the first challenges in a natural disaster or humanitarian emergency is to obtain accurate estimates of affected populations (1). In the aftermath of rapid-onset disasters such as the recent tsunami disaster in south Asia, there is frequently an absence of adequate baseline data against which to measure the impact of the disaster. Available population data vary widely in quality, and the...
متن کاملEstimating effective population size and migration rates from genetic samples over space and time.
In the past, moment and likelihood methods have been developed to estimate the effective population size (N(e)) on the basis of the observed changes of marker allele frequencies over time, and these have been applied to a large variety of species and populations. Such methods invariably make the critical assumption of a single isolated population receiving no immigrants over the study interval....
متن کاملCentre Sampling for Estimating Elusive Population Size
The estimation of the size of an elusive population is a problem frequently addressed in many fields of applications. In the paper a sampling strategy for the estimation of the size, named centre sampling, is proposed, and its properties are evaluated in a design-based approach. The estimator is admissible, consistent and the design is measurable. The expressions of the variance of the populati...
متن کاملEstimating contemporary effective population size on the basis of linkage disequilibrium in the face of migration.
Effective population size (Ne) is an important genetic parameter because of its relationship to loss of genetic variation, increases in inbreeding, accumulation of mutations, and effectiveness of selection. Like most other genetic approaches that estimate contemporary Ne, the method based on linkage disequilibrium (LD) assumes a closed population and (in the most common applications) randomly r...
