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

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.

Counting Cats: Spatially Explicit Population Estimates of Cheetah (Acinonyx jubatus) Using Unstructured Sampling Data. [PDF]

open access: yesPLoS ONE, 2016
Many ecological theories and species conservation programmes rely on accurate estimates of population density. Accurate density estimation, especially for species facing rapid declines, requires the application of rigorous field and analytical methods ...

Evaluating heterogeneity of sex‐specific capture probability and precision in camera‐trap population estimates of tigers

open access: yesWildlife Society Bulletin, 2014
Population estimates of tigers (Panthers tigris) are affected by movement patterns of the sexes. We evaluated sex‐specific heterogeneity to estimate the tiger population at Ranthambhore Tiger Reserve, western Rajasthan, India. We also compared population

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 ...

Estimating Key Largo woodrat abundance using spatially explicit capture–recapture and trapping point transects

open access: yesWildlife Society Bulletin, 2016
The Key Largo woodrat (Neotoma floridana smalli) is an endangered rodent with a restricted geographic range and small population size. Establishing an efficient monitoring program of its abundance has been problematic; previous trapping designs have not ...

Reproducible Production of Lithium-Ion Coin Cells

open access: yesEnergies, 2022
Due to the simple structure and the possibility of manual production, coin cells enable fast and, compared to larger cell formats, an inexpensive examination option in battery research.

SECRS TEMPLATE TO AID NOVICE DEVELOPERS IN SECURITY REQUIREMENTS IDENTIFICATION AND DOCUMENTATION

open access: yesInternational Journal of Software Engineering and Computer Systems, 2022
The security requirements are one of the non-functional requirements (NFR) which acts as a constraint on the functions of the system to be built. Security requirements are important and may affect the entire quality of the system. Unfortunately, many organizations do not pay much attention to it.

Effect of Water Saturation on the Diffusion/Adsorption of 22Na and Cesium onto the Callovo-Oxfordian Claystones

open access: yesGeofluids, 2017
The diffusion and adsorption behaviors of sodium and cesium were investigated in the Callovo-Oxfordian claystones (France) under unsaturated conditions.

mHealth intervention for carers of individuals with a history of stroke: Heuristic evaluation and user perspectives

open access: yesDigital Health, 2022
Background Caregiving in stroke is complex, with most carers having little to no preparation to care for individuals with a history of stroke, leading to emotional impact.
