Parsimonious Modelling of Capture-Mark-Recapture Studies

Biometrics, 1985
A general multinomial modelling approach is proposed for capture-mark- recapture data from an open animal population. Within this framework a number of plausible alternative assumptions are suggested for survival probabilities, ingress times, and capture probabilities.

Mark-Recapture Models with Parameters Constant in Time

Biometrics, 1982
The Jolly-Seber method, which allows for both death and immigration, is easy to apply but often requires a larger number of parameters to be estimated tha would otherwise be necessary. If (i) survival rate, phi, or (ii) probability of capture, p, or (iii) both phi and p can be assumed constant over the experimental period, models with a reduced number ...

Trap mortality in mark-recapture studies

Environmental and Ecological Statistics, 2009
When animals die in traps in a mark-recapture study, straightforward likelihood inferences are possible in a class of models. The class includes M0, Mt, and Mb as reported by White et al. (Los Alamos National Laboratory, LA-8787-NERP, pp 235, 1982), those that do not involve heterogeneity.

Variances of Mark-Recapture Estimates

Biometrics, 1993
When mark-recapture data are analysed by log-linear models, as described by Cormack (1989, Biometrics 45, 395-413), the analysis is in terms of parameters that are related nonlinearly to the parameters of biological interest. For several models formulae are given expressing the variance of the interesting parameter estimates in terms of those provided ...

Mark–Recapture: Basic Models

2019
We consider two basic live-recapture models referred to as the CJS model (after Cormack–Jolly–Seber) that models the tagged data, and the JS model (after Jolly and Seber in Biometrika, 52:225–247, 1965), which also includes the untagged data. Likelihood methods as originally used are described, while Bayesian and random-effects methods have since been ...

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 ...

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 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.
