ipsecr: An R package for awkward spatial capture–recapture data

open access: yesMethods in Ecology and Evolution, 2023
Some capture–recapture models for population estimation cannot easily be fitted by the usual methods (maximum likelihood and Markov‐chain Monte Carlo).

A spatially explicit approach for estimating space use and density of common genets [PDF]

open access: yesAnimal Biodiversity and Conservation, 2014
Many species that occur at low densities are not accurately estimated using capture–recapture methods as such techniques assume that populations are well–defined in space.

Application of Spatial and Closed Capture-Recapture Models on Known Population of the Western Derby Eland (Taurotragus derbianus derbianus) in Senegal. [PDF]

open access: yesPLoS ONE, 2015
Camera trapping with capture-recapture analyses has provided estimates of the abundances of elusive species over the last two decades. Closed capture-recapture models (CR) based on the recognition of individuals and incorporating natural heterogeneity in

Determination of the Distribution of Relaxation Times by Means of Pulse Evaluation for Offline and Online Diagnosis of Lithium-Ion Batteries

open access: yesBatteries, 2021
The distribution of relaxation times (DRT) analysis of impedance spectra is a proven method to determine the number of occurring polarization processes in lithium-ion batteries (LIBs), their polarization contributions and characteristic time constants ...

Síndrome erosivo corneal recurrente enmascarado como queratitis epitelial herpética

open access: yesRevista Mexicana de Oftalmología, 2015
Introducción: . El cuadro clínico del síndrome erosivo corneal recurrente (SECR) puede ser confundido con el de la queratitis epitelial herpética. Materiales y métodos: Serie de casos de SECR con diagnóstico erróneo de queratitis epitelial herpética en ...

An Efficient Acoustic Density Estimation Method with Human Detectors Applied to Gibbons in Cambodia.

open access: yesPLoS ONE, 2016
Some animal species are hard to see but easy to hear. Standard visual methods for estimating population density for such species are often ineffective or inefficient, but methods based on passive acoustics show more promise. We develop spatially explicit

Accounting for heterogeneous density and detectability in spatially explicit capture–recapture studies of carnivores

open access: yesEcosphere, 2023
Reliable estimates of population density are fundamental for managing and conserving wildlife. Spatially explicit capture–recapture (SECR) models in combination with information‐theoretic model selection criteria are frequently used to estimate ...

Bayes and empirical Bayes estimators of abundance and density from spatial capture-recapture data. [PDF]

open access: yesPLoS ONE, 2013
In capture-recapture and mark-resight surveys, movements of individuals both within and between sampling periods can alter the susceptibility of individuals to detection over the region of sampling.
