An 11-digit identification system for individual Nile crocodiles using natural markings

open access: yesKoedoe: African Protected Area Conservation and Science, 2016
Research and conservation of wild crocodiles and husbandry of captive crocodiles requires the reliable identification of individuals. We present a method using the individual colour markings on the first 10 single-crest scutes on the tails of Nile ...

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.

State–space mark–recapture estimates reveal a recent decline in abundance of North Atlantic right whales

open access: yesEcology and Evolution, 2017
North Atlantic right whales (Eubalaena glacialis Müller 1776) present an interesting problem for abundance and trend estimation in marine wildlife conservation.

Towards the mother-of-all-models: customised construction of the mark-recapture likelihood function [PDF]

open access: yesAnimal Biodiversity and Conservation, 2004
With a proliferation of mark–recapture models and studies collecting mark–recapture data, software and analysis methods are being continually revised. We consider the construction of the likelihood for a general model that incorporates all the features ...

An evaluation of population indices for northern bobwhite

open access: yesWildlife Society Bulletin, 2019
Northern bobwhite (Colinus virginianus) populations are monitored using 2 general approaches—population indices and abundance estimators. Due to their convenient sampling designs, indices are commonly used by land managers and researchers to predict or ...

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.

Absolute abundance of southern bluefin tuna estimated by close-kin mark-recapture

open access: yesNature Communications, 2016
Southern bluefin tuna is a highly valuable, severely depleted species, whose abundance and productivity have been difficult to assess with conventional fishery data.

Home‐site fidelity and homing behavior of the big‐headed turtle Platysternon megacephalum

open access: yesEcology and Evolution, 2021
Site fidelity refers to the restriction of dispersal distance of an animal and its tendency to return to a stationary site. To our knowledge, the homing ability of freshwater turtles and their fidelity is reportedly very low in Asia.
