Mark-Recapture Estimates with Emigration and Re-Immigration
Biometrics, 1990A technique is outlined for analysing mark-recapture data from an animal population in which individuals may emigrate from the study area and later return. Maximum likelihood estimates of population parameters are calculated. Likelihood ratio tests are used to examine whether re-immigration is actually occurring, and, if not, whether there is any ...

Capture�mark�recapture, removal sampling, and occupancy models
2009Abstract Understanding the distribution and abundance of organisms is frequently stated as the objective of ecological investigations (Elton 1927; Krebs 1972). Similarly, distribution and abundance are primary criteria used to classify the status of species (e.g. threatened, endangered) for conservation purposes (Gardenfors et al. 2001).

A Bayesian mark–recapture model for multiple-recapture data in a catch-and-release fishery
Canadian Journal of Fisheries and Aquatic Sciences, 2009This paper extends a state–space Bayesian mark–recapture framework to multiple-recapture data to estimate fishery-specific capture and mortality rates and seasonal movement rates for fish in different length classes. The methodology is applied to tag recapture data for white sturgeon ( Acipenser transmontanus ) collected in the recreational fishery and

Estimation of Rates of Births, Deaths, and Immigration from Mark–Recapture Data
Biometrics, 2009Summary The analysis of mark–recapture data is undergoing a period of development and expansion. Here we contribute to that by presenting a model which includes both births and immigration, as well as the usual deaths. Data come from a long‐term study of the willow tit (Parus montanus), where we can assume that all births are recorded, and hence ...

Abalone I: Analyzing Mark‐Recapture‐Recovery Data Incorporating Growth and Delayed Recovery
Biometrics, 2001Summary. Abalone are semimobile marine gastropods that form the basis of Australia's second most valuable fishery. A site off the coast of Port Arthur, Tasmania, was visited on six occasions. On each occasion, any unmarked live abalone found were marked with a unique identification number and were recorded.

NautilusGrowth and Longevity: Evidence from Marked and Recaptured Animals
Science, 1984Study ofNautilus belauensisin its natural habitat in Palau, West Caroline Islands, shows that growth is slow (0.1 millimeter of shell per day on the average) and decreases as maturity is approached and that individuals may live at least 4 years beyond maturity.

Combining line transect and capture-recapture for mark-resighting studies
2021Distance sampling and capture-recapture methods have been widely used to estimate density and abundance of wildlife populations. We propose a population estimator for a mark-resighting study where in the resighting stage perpendicular distance data is recorded.

Mark-Recapture Creel Survey and Survival Models
1997In this dissertation, we consider a model based approach to the estimation of exploitation rate of a fish population by combining mark-recapture procedures with a creel survey. We also consider the analysis of a proportional hazards survival model for randomly censored observations, known as the Koziol-Green model.

The effects of marking and capture on recapture frequencies of butterflies
Oecologia, 1982As a preliminary to a population study using markrelease-recapture techniques, specimens of the Satyrid buttfly Melanargia galathea (L.) were subjected to a number of marking and capture techniques. Although the adults are thought to display both aposematic and cryptic coloration, the use of marks of different sizes and colours had no significant ...

Dispersal ability in codling moth: mark–release–recapture experiments and kinship analysis
Agricultural and Forest Entomology, 2012The present study focused on the dispersal patterns in the codling moth because such information is fundamental for determining the dynamics and genetics of the pest populations and for developing efficient management programmes.
