Estimation Methodology in Contemporary Small Mammal Capture-Recapture Studies
TLDR
The Jolly-Seber estimators are shown to be superior even in the case of heterogeneity and trap-happy response, the two sources of unequal capture probability most likely to occur in small mammal studies.Abstract:
Estimators of population size and survival rate based on the Jolly-Seber capture-recapture model and the “enumeration method” are described. Enumeration estimators are shown to estimate complicated functions of capture and survival probabilities and, in the case of the population size estimator, population size. Frequently-listed reasons for preferring enumeration estimators are discussed and the Jolly-Seber estimators are shown to be superior even in the case of heterogeneity and trap-happy response, the two sources of unequal capture probability most likely to occur in small mammal studies. New developments in probabilistic capture-recapture models are described, and these models are recommended for future small mammal capture-recapture studies.read more

Modeling Survival and Testing Biological Hypotheses Using Marked Animals: A Unified Approach with Case Studies
TL;DR: A recent survey of capture-recapture models can be found in this article, with an emphasis on flexibility in modeling, model selection, and the analysis of multiple data sets.
Modeling Survival and Testing Biological Hypotheses Using Marked Animals: A Unified
TL;DR: This paper synthesizes, using a common framework, recent developments of capture-recapture models oriented to estimation of survival rates together with new ones, with an emphasis on flexibility in modeling, model selection, and the analysis of multiple data sets.

A double-observer approach for estimating detection probability and abundance from point counts
James D. Nichols,James E. Hines,John R. Sauer,Frederick W. Fallon,Jane E. Fallon,Patricia J. Heglund +5 more
TL;DR: In this paper, a double-observer approach was applied to estimate detection probabilities for aerial surveys (Cook and Jacobson 1979) to avian point counts, where a designated primary observer indicates to another (secondary) observer all birds detected.
Journal ArticleDOI
A review of estimating animal abundance.
TL;DR: A review of the literature in the estimation of animal abundance and related parameters such as survival rates and suggest further avenues for research.

A note on the multiple-recapture census.
TL;DR: Jolly (1965), tackling this problem from a different viewpoint, gives a very elegant solution to the problem of finding maximumlikelihood estimates of the unknown population parameters and gives the means and variances of these estimates.
