Mark—recapture experiments

1985
Mark—recapture methods were originally developed for estimating the size of mobile animal populations. However, it was soon recognized that the same methods could be used for estimating survival rates in the wild. It was then a short step to using the same approach for comparing the survival rates of different morphs in a polymorphic population.

Mark-recapture analysis of a known population

Journal of Biological Education, 1977
Problems involved with demonstrating mark-recapture techniques in ecology classes are discussed. An exercise which overcomes most of these difficulties using a known, restricted population of people is described. Jolly-Seber estimates of the size of this population varied in precision and accuracy with method and intensity of sampling, more or less as ...

Mark‐recapture estimates of injecting drug users in Sydney

Australian Journal of Public Health, 1994
Abstract: The number of injecting drug users in the Central and Eastern Sydney Area Health Services (CSAHS and ESAHS) in 1989–1990 was estimated by applying the Petersen mark‐recapture method to data obtained from the Australian National AIDS and Injecting Drug Use Surveys conducted in 1989 and in 1990.

A White Shrimp Mark-Recapture Study

Transactions of the American Fisheries Society, 1974
Abstract Marked sub-adult white shrimp were released in Galveston Bay in August 1963. Recoveries indicated there was no emigration from the bay between August and mid-October. Using the Bertalanffy growth function estimates of L∞ equals 214 mm, K = 0.09 (sexes combined).

Mark–recapture experiments with freshwater organisms

Journal of Biological Education, 1991
The population of Gyrinus, the whirligig beetle, is assessed using the Lincoln mark—recapture index. This technique has the advantage of helping the student to understand simple proportion as well as other concepts.

A self-checking coding technique for mark-recapture studies

Bulletin of Entomological Research, 1970
A technique is described in which twelve symbols or fewer can be chosen to code insects with individual marks suitable for mark-recapture studies. The method has been tested on Acrididae and has the advantages that (i) the code is self-checking against loss of marks, (ii) the application is practical, as only one colour is applied to a given individual,

Interval Estimation for Mark-Recapture Studies of Closed Populations

Biometrics, 1992
Textbooks continue to recommend the use of an asymptotic normal distribution to provide an interval estimate for the unknown size, N, of a closed population studied by a mark-recapture experiment or multiple-record system. A likelihood interval approach is proposed and its implementation demonstrated for a range of models for such studies, including ...

Open-Population Mark-Recapture Models

2014
Many of the developments in mark-recapture methodology have been designed for open animal populations, with new animals entering through births and immigration and animals leaving through deaths and emigration. Studies usually involve sampling the population several times, with animals suitably marked when they are first captured so that they can ...
