Apparent survival probability and abundance of juvenile green turtles in the foraging ground at Kuroshima Island, Ryukyu Archipelago

open access: yesEndangered Species Research, 2023
An understanding of the survival probability and abundance of endangered species is critical for their effective conservation and management. In this study, long-term capture-mark-recapture data were used to estimate the apparent survival probability and

An empirical Bayesian approach to incorporate directional movement information from a forage fish into the Arnason-Schwarz mark-recapture model

open access: yesMovement Ecology, 2021
Background Over the past two decades, various species of forage fish have been successfully implanted with miniaturized acoustic transmitters and subsequently monitored using stationary acoustic receivers.

Long‐term apparent survival of a cold‐stunned subpopulation of juvenile green turtles

open access: yesEcosphere, 2022
Understanding the effects of extreme weather on animal populations is fundamental to ecological and conservation sciences and species management. Climate change has resulted in both warm and cold temperature extremes, including an increased frequency of ...

VARIACIÓN DEMOGRÁFICA TEMPORAL DE LA TORTUGA DE RÍO CHOCOANA, Rhinoclemmys nasuta (GEOEMYDIDAE), EN ISLA PALMA, BAHÍA MÁLAGA, PACÍFICO DEL VALLE DEL CAUCA

open access: yesActa Biológica Colombiana, 2014
Pocos estudios demográficos de larga duración han sido realizados en tortugas dulceacuícolas de Suramérica, pese a la necesidad de este tipo de investigación para esclarecer las variaciones naturales y fortalecer procesos de conservación en este grupo ...

Full Open Population Capture-Recapture Models with Individual Covariates [PDF]

open access: yes, 2010
Traditional analyses of capture-recapture data are based on likelihood functions that explicitly integrate out all missing data. We use a complete data likelihood (CDL) to show how a wide range of capture-recapture models can be easily fitted using ...

Aspects of demography in three distinct populations of garden dormouse, Eliomys quercinus, across Italy and Spain [PDF]

open access: yes, 2016
Comparative aspects of the demography were investigated in three distinct populations of the ecologically poorly studied rodent Eliomys quercinus, in Spain and Italy.

Capture-mark-recapture modelling suggests an Endangered status for the Mayotte Island (eastern Africa) population of Indo-Pacific bottlenose dolphins

open access: yesEndangered Species Research, 2014
We evaluated whether the Indo-Pacific bottlenose dolphins around the fast-developing island of Mayotte are threatened. We used opportunistic photo-identification data and capture-mark-recapture models to estimate key demographic parameters and then ...

Cryptic disease-induced mortality may cause host extinction in an apparently stable host- parasite system [PDF]

open access: yes, 2017
The decline of wildlife populations due to emerging infectious disease often shows a common pattern: the parasite invades a naive host population, producing epidemic disease and a population decline, sometimes with extirpation.

Cormack-Jolly-Seber models: time and age perspectives [PDF]

open access: yes, 2020
Survival is a key demographic characteristic in many areas including both humandemography and population ecology. However, it is often the case that data collection protocols are different in these areas, resulting in different models and methods of ...

Population ecology of Chaetophractus vellerosus: the first report for an armadillo in South America

open access: yesZoologia (Curitiba), 2017
The aim of this work was to obtain the first estimates of survival rates (S), capture probability (p) and life expectancy for armadillos in South America by analyzing capture-mark-recapture data obtained from a population of Chaetophractus vellerosus ...
