Long-term trends in the use of a protected area by small cetaceans in relation to changes in population status [PDF]

open access: yesGlobal Ecology and Conservation, 2014
The requirement to monitor listed species in European designated sites is challenging for long-lived mobile species that only temporarily occupy protected areas.

Application of network theory to mark recapture data allows insights into population structure of two Heliconius species [PDF]

open access: yesNetwork Biology, 2015
By noting the spatial location of captured individuals mark-recapture studies create a collection of discrete events spread in space and time. This setup is appropriate for network modeling where the vertices (or nodes) are the points of capture and ...

Embedding population dynamics in mark-recapture models [PDF]

open access: yes, 2009
Mark-recapture methods use repeated captures of individually identifiable animals to provide estimates of properties of populations. Different models allow estimates to be obtained for population size and rates of processes governing population dynamics.

Bayesian mark–recapture–resight–recovery models: increasing user flexibility in the BUGS language

open access: yesEcosphere, 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.

Integrating growth and survival models for flexible estimation of size‐dependent survival in a cryptic, endangered snake

open access: yesEcology and Evolution, 2022
Estimates of demographic rates for animal populations and individuals have many applications for ecological and conservation research. In many animals, survival is size‐dependent, but estimating the form of the size–survival relationship presents ...

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

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.

Estimating the population structure of Javan rhinos (Rhinoceros sondaicus) in Ujung Kulon National Park using the mark- recapture method based on video and camera trap identification

open access: yesPachyderm, 2011
The population structure of the Javan rhino (Rhinoceros sondaicus) in Ujung Kulon National Park (NP) in Banten, Indonesia was assessed using visual identification and mark-recapture estimation.

A non-technical overview of spatially explicit capture-recapture models [PDF]

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 ...

Monitoring Brazilian Cavefish: Ecology and Conservation of Four Threatened Catfish of Genus Ituglanis (Siluriformes: Trichomycteridae) from Central Brazil

open access: yesDiversity, 2021
We investigated population parameters using the capture-mark-recapture method (Ituglanis passensis and I. bambui) and visual censuses (I. epikasrticus and I. ramiroi).

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 ...
