Integrating telemetry data at several scales with spatial capture–recapture to improve density estimates

open access: yesEcosphere, 2021
Accurate population estimates are essential for monitoring and managing wildlife populations. Mark–recapture sampling methods have regularly been used to estimate population parameters for rare and cryptic species, including the federally listed Mojave ...

Mark‐Recapture with Multiple, Non‐Invasive Marks [PDF]

open access: yesBiometrics, 2013
AbstractSummaryNon‐invasive marks, including pigmentation patterns, acquired scars, and genetic markers, are often used to identify individuals in mark‐recapture experiments. If animals in a population can be identified from multiple, non‐invasive marks then some individuals may be counted twice in the observed data.

Recapture heterogeneity in cliff swallows: increased exposure to mist nets leads to net avoidance. [PDF]

open access: yesPLoS ONE, 2013
Ecologists often use mark-recapture to estimate demographic variables such as abundance, growth rate, or survival for samples of wild animal populations.

Survival rates of adult and juvenile gyrfalcons in Iceland: estimates and drivers [PDF]

open access: yesPeerJ, 2021
Knowledge of survival rates and their potential covariation with environmental drivers, for both adults and juveniles, is paramount to forecast the population dynamics of long-lived animals.

Does Your Species Have Memory? Analysing Capture-Recapture Data with Memory Models. [PDF]

open access: yes, 2014
1. We examine memory models for multi-site capture-recapture data. This is an important topic,as animals may exhibit behaviour that is more complex than simple first-order Markov movement between sites, when it is necessary to devise and fit appropriate ...

A generalised likelihood framework for partially observed capture-recapture-recovery models

open access: yes, 2013
We provide a closed form likelihood expression for multi-state mark-recapture-recovery data when the state of an individual may be only partially observed.

Mark-recapture locations (Junco hyemalis)

open access: yes, 2013
This file includes mark-recapture locations for nestlings banded in the nest on Salt Pond Mountain, VA from 1996-2006 that were also recaptured or nested the next year as adults.

A non-technical overview of spatially explicit capture-recapture models

open access: yes, 2010
Most capture-recapture studies are inherently spatial in nature, with capture probabilities depending on the location of traps relative to animals. The spatial component of the studies has until recently, however, not been incorporated in statistical ...
