ESTIMATING AND VISUALIZING FITNESS SURFACES USING MARK-RECAPTURE DATA [PDF]
Evolution, 2009 Understanding how selection operates on a set of phenotypic traits is central to evolutionary biology. Often, it requires estimating survival (or other fitness-related life-history traits) which can be difficult to obtain for natural populations because individuals cannot be exhaustively followed.

Recapture heterogeneity in cliff swallows: increased exposure to mist nets leads to net avoidance. [PDF]
PLoS ONE, 2013 Ecologists often use mark-recapture to estimate demographic variables such as abundance, growth rate, or survival for samples of wild animal populations.

Global Ecology and Conservation, 2020 Estimating abundance is one of the most fundamental and important aspects of population biology, with major implications on how the status of a population is perceived and thus on conservation and management efforts.

Considering sampling bias in close‐kin mark–recapture abundance estimates of Atlantic salmon
Ecology and Evolution, 2021 Genetic methods for the estimation of population size can be powerful alternatives to conventional methods. Close‐kin mark–recapture (CKMR) is based on the principles of conventional mark–recapture, but instead of being physically marked, individuals are

Simple Estimation and Test Procedures in Capture–Mark–Recapture Mixed Models [PDF]
Biometrics, 2011 SummaryThe need to consider in capture‐recapture models random effects besides fixed effects such as those of environmental covariates has been widely recognized over the last years. However, formal approaches require involved likelihood integrations, and conceptual and technical difficulties have slowed down the spread of capture–recapture mixed ...

Bayesian mark–recapture–resight–recovery models: increasing user flexibility in the BUGS language
Ecosphere, 2021 Estimating demographic parameters of interest is a critical component of applied conservation biology and evolutionary ecology, where demographic models and demographic data have become increasingly complex over the last several decades.

Ecology and Evolution, 2020 Close‐kin mark–recapture (CKMR) is a method for estimating abundance and vital rates from kinship relationships observed in genetic samples. CKMR inference only requires animals to be sampled once (e.g., lethally), potentially widening the scope of ...

Costs and Precision of Fecal DNA Mark–Recapture versus Traditional Mark–Resight
Wildlife Society Bulletin, 2020 ABSTRACT Wildlife managers often need to estimate population abundance to make well‐informed decisions. However, obtaining such estimates can be difficult and costly, particularly for species with small populations, wide distributions, and spatial clustering of individuals. For this reason, DNA surveys and capture–

Rejection of Schmidt et al.'s estimators for bear population size
Ecology and Evolution, 2019 Aerial distance sampling of bears to estimate population size has been used throughout many parts of Alaska. The distance sampling models are complex since they need to account for undetected bears and differences in detection probabilities.
