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 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 کاملCaptive breeding and the reintroduction of Mexican and red wolves.
Mexican and red wolves were both faced with extinction in the wild until captive populations were established more than two decades ago. These captive populations have been successfully managed genetically to minimize mean kinship and retain genetic variation. Descendants of these animals were subsequently used to start reintroduced populations, which now number about 40-50 Mexican wolves in Ar...
متن کاملTools and Technology Hair of the Dog: Obtaining Samples From Coyotes and Wolves Noninvasively
Canids can be difficult to detect and their populations difficult to monitor. We tested whether hair samples could be collected from coyotes (Canis latrans) in Texas, USA and gray wolves (C. lupus) in Montana, USA using lure to elicit rubbing behavior at both man-made and natural collection devices. We used mitochondrial and nuclear DNA to determine whether collected hair samples were from coyo...
