This technique has long been at the forefront of quantitative ecology, epidemiology and the social sciences for estimating the size of populations that are difficult to count directly. By using ...

The assumption of equal catchability of marked and unmarked animals in mark-recapture sampling is examined. Violation of this assumption may come from two basic sources, heterogeneity or contagion, ...

An innovative new method of estimating the density of snake populations without employing the capture-mark-recapture technique has been created by a biologist. How can researchers determine the number ...

In this paper, we describe a method for estimating animal population density per unit area from mark, release, recapture (MRR) data. Standard procedures are available for estimating population size ...
