A multiple mark and recapture estimate applied to polar bears

Canadian Journal of Zoology, 1980
The mark–recapture technique described in this paper estimates polar bear (Ursus maritimus) populations for all sample periods except the first sample period, incorporates an open population model, and is supported by ecological data from ringed seals and polar bears.

Extreme variability in European eel growth revealed by an extended mark and recapture experiment in southern France and implications for management

Canadian Journal of Fisheries and Aquatic Sciences, 2022
The European eel (Anguilla anguilla) is endangered due to its peculiar life-history cycle, fishing pressure and difficulty in global population management.

Red snapper, Lutjanus campechanus, abundance on oil and gas platforms based on mark-recapture methods in the northern Gulf of Mexico.

Canadian Journal of Fisheries and Aquatic Sciences, 2022
Oil and gas platforms provide reef habitat for many fish species on continental shelves. Red snapper, Lutjanus campechanus, are an important component of these communities in the Gulf of Mexico, but abundance estimates are difficult to obtain ...

Mark‐release‐recapture of ticks: A case study of estimating the abundance of Ixodes persulcatus (Acari, Ixodidae)

Medical and Veterinary Entomology, 2022
In this study, we tested the applicability of three common methods of absolute abundance estimation—Peterson, Bailey and Jolly‐Seber—to Ixodes persulcatus ticks based on mark‐release‐recapture data.

A labor‐saving marking and sampling technique for mark‐release‐recapture research

Entomologia Experimentalis et Applicata, 2022
AbstractA marking and recapture sampling method was developed that shows promise for studying the dispersal behavior of small and delicate arthropods. Adult sweetpotato whiteflies, Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae), were externally marked with a liquid fluorophore that glows brightly under ultraviolet (UV) light.

Recent Models for Mark-Recapture and Mark-Resighting Data

Biometrics, 1987
A topic of current interest in the analysis of capture-recapture data is the development of models that allow biologically meaningful constraints on survival and capture rates. Of particular interest are models in which survival is a function of environmental variables.

Tag loss and the Petersen mark-recapture experiment

Biometrika, 1981
SUMMARY A problem in the Petersen capture-mark-recapture experiment (Seber, 1973, Chapter 3) is the possible loss of tags. The effect of such a loss on the usual estimate of population size and the estimate of its variance is investigated for both single and double tagging.

Mark–recapture studies and demography

2008
AbstractPopulation ecologists track wild animals over their lifetimes using mark-recapture methods. Odonates are easily marked and remain near water bodies, allowing for high recapture rates. In recent years, the focus in mark-recapture models has switched from population size estimates to survival and recapture rate estimation, and from testing ...

Methods to mark termites with protein for mark–release–recapture and mark–capture type studies

Insectes Sociaux, 2009
Studies were conducted to investigate the feasibility of marking the southwestern desert subterranean termite, Heterotermes aureus (Snyder), with rabbit immunoglobulin G (IgG) protein for mark–release–recapture (MRR) and mark–capture type studies. Qualitative laboratory studies were conducted to determine how long reagent-grade rabbit IgG is retained ...
