Integrating Mark–Recapture–Recovery and Census Data to Estimate Animal Abundance and Demographic Parameters

Summary. In studies of wild animals, one frequently encounters both census and mark‐recapture‐recovery data. We show how a state‐space model for census data in combination with the usual multinomial‐based models for ring‐recovery data provide estimates of productivity not available from either type of data alone. The approach is illustrated on two British bird species. For the lapwing, we calibrate how its recent decline could be due to a decrease in productivity. For the heron, there is no… 

A Bayesian approach to combining animal abundance and demographic data

This paper focuses upon the analysis of both count and recovery data collected on British lapwings combined with records of the number of frost days each winter, and discusses how the Bayesian approach using MCMC allows us to remove the potentially restrictive normality assumptions commonly assumed for analyses of this sort.

Integrated data analysis in the presence of emigration and mark loss

Integrated data analyses are becoming increasingly common in studies of wild animal populations where two or more separate sources of data contain information about common parameters. These types of

Inferences about population dynamics from count data using multistate models: a comparison to capture–recapture approaches

This work extends recently developed multistate, open population N-mixture models, which can additionally estimate demographic rates based on an organism's life history characteristics, and develops an approach to account for the case where not all individuals can be assigned to a state during sampling.

Using encounter data to improve capture-recapture abundance estimates

It is shown that failed captures provide lower bounds on population size that can increase the precision of abundance estimates, and a hierarchical Bayesian approach is presented for integrating failed captures and auxiliary encounter data in statistical capture-recapture models.

Combining ground count, telemetry, and mark–resight data to infer population dynamics in an endangered species

Summary 1. To successfully manipulate populations for management and conservation purposes, managers must be able to track changes in demographic rates and determine the factors driving spatial and

Quantifying changes in abundance without counting animals: extensions to a method of fitting integrated population models

The extent to which high-quality demographic data, used in conjunction with an ecologically sound model, may result in credible estimates of change and the drivers of it in the context of either counts or presence/absence survey data is considered.

Studying dispersal at the landscape scale: efficient combination of population surveys and capture-recapture data.

It is suggested that first-time breeders disperse to small colonies in order to recruit earlier, and patterns of condition-dependent dispersal are made easier to detect, and evidence for colony-size dependence in recruitment, dispersal, and breeding success is obtained.

Potential contributions of capture–recapture to the estimation of population growth rate in restoration projects

This alternative method can easily be put in practice during restoration projects because reintroduced animals can be tagged before release and estimated directly from capture-recapture data, and enables evaluation of the demographic processes responsible for variation in population size.

An Integrated Population Model From Constant Effort Bird-Ringing Data

A Bayesian approach and a deterministic population model uniting abundance, productivity, and survival are developed and applied to sedge warbler Acrocephalus schoenobaenus data from the British Trust for Ornithology’s Constant Effort Sites scheme.


Recent work has shown how the Kalman filter can be used to provide a simple framework for the integrated analysis of wild animal census and mark‐recapture‐recovery data. The approach has been applied



A simultaneous survival rate analysis of dead recovery and live recapture data

In long term studies on birds one frequently encounters both dead recovery data, from birds marked as young, and live recapture data, typically from birds ringed as breeding adults. However the two

Integrated recovery/recapture data analysis

The integration of recovery and recapture data, providing information on the same individuals, is important for the stable fitting of a wide range of stochastic models, resulting in more realistic

The efficient integration of abundance and demographic data

A drawback of a new method for integrating abundance and mark-recapture-recovery data is the need to combine likelihoods describing the different data sets, which is easily circumvented by the use of a multivariate normal approximation.

Factors influencing Soay sheep survival

A survival analysis of Soay sheep mark recapture and recovery data is presented, with a substantial variation in the recovery probabilities over time, reflecting in part the increased effort when a population crash was expected.


A stochastic model for the movement and eventual mortality of an individual animal is formulated as a combination of three components: initial spatial location, survival status at any point in time,

Modelling Heron Survival Using Weather Data

There is a definite needfor methodology which will produce ageand time-specific survival probabilities from bird ringing studies in which only nestlings are ringed, and one possible approach to this


Knowledge of the direction, magnitude, and timing of changes in bird population abundance is essential to enable species of priority conservation concern to be identified, and reasons for the

Approaches for the direct estimation of u , and demographic contributions to u , using capture-recapture data

We first consider the estimation of the finite rate of population increase or population growth rate, u i , using capture-recapture data from open populations. We review estimation and modelling of u

Analysis of monitoring data with many missing values: which method?

Large-scale monitoring of bird species becomes more and more important in many countries. In the datasets yielded by these censuses, values are often missing. This poses problems in the analysis of

Modelling the survival of British Lapwings Vanellus vanellus using ring-recovery data and weather covariates

Two sets of data are considered. One describes recovery data from Lapwings ringed as young in Britain in 1963–¸92. The other provides several weather covariates for the same period, and our objective
