Validation of close-kin mark–recapture (CKMR) methods for estimating population abundance [PDF]

Methods in Ecology and Evolution, 2019
Abstract Knowing how many individuals there are in a population is a fundamental problem in the management and conservation of freshwater and marine fish. We compare abundance estimates (census size, Nc) in seven brook trout Salvelinus fontinalis populations using standard mark–recapture (MR) and the close‐kin mark–recapture (CKMR) method.

Combining individual and close-kin mark-recapture to design an effective wildlife population survey. [PDF]

Ecology
Abstract Close‐kin mark–recapture (CKMR) is a promising approach for assessing population size of species that have been difficult to survey using more traditional methods. Here, we combine individual and close‐kin mark–recapture in a single modeling framework (ICKMR) and provide an example of study design using this approach for Pacific walrus ...

Estimation of Adult Census Size From Close‐Kin Dyads in the Malaria Mosquito Anopheles gambiae [PDF]

Evol Appl
ABSTRACT Accurate estimates of adult mosquito abundance are central to the design and evaluation of vector control strategies, yet they are difficult to obtain from natural populations. Conventional mark‐recapture methods for estimating adult mosquito census size pose logistical and other challenges. A recently developed close‐kin mark‐recapture (CKMR)

Application of close‐kin mark–recapture to an American black bear population using harvest samples [PDF]

Ecol Appl
Abstract Close‐kin mark–recapture (CKMR) offers a promising alternative to traditional mark–recapture methods for estimating wildlife population parameters. CKMR estimates demographic parameters by identifying genetic relationships between individuals, effectively “recapturing” parental genotypes through their offspring's genetic profiles.

Move and Play Programme: Perceptions of Paediatric Physiotherapists and Parents of Infants. [PDF]

Child Care Health Dev
ABSTRACT Introduction Educational videos can improve parent engagement in early childhood development. For widespread adoption, these videos need to be practical and of high quality. This study evaluated how paediatric physiotherapists and parents perceived the educational videos of the ‘Move and Play Programme’.

Simulation-Based Spatially Explicit Close-Kin Mark-Recapture. [PDF]

Mol Ecol Resour
ABSTRACT Estimating the size of wild populations is a critical priority for ecologists and conservation biologists, but tools to do so are often labour intensive and expensive. A promising set of newer approaches are based on genetic data, which can be cheaper to obtain and less invasive than information from more direct observation.

Age-Specific Normative Values for the Sitting-Rising Test in Brazilian Children and Adolescents. [PDF]

J Paediatr Child Health
ABSTRACT Introduction Functional assessment of children and adolescents is essential for monitoring motor development and for the prevention of deficits that may impact health and quality of life. In primary care contexts, the implementation of simple and cost‐effective tests has been a pragmatic strategy, particularly in low‐ and middle‐income ...

Collapsible Kernel Machine Regression for Exposomic Analyses. [PDF]

Stat Med
ABSTRACT An important goal of environmental epidemiology is to quantify the complex health effects posed by a wide array of environmental exposures. In studies of a small number of exposures, flexible models like Bayesian kernel machine regression (BKMR) are appealing because they allow for non‐linear and non‐additive associations among exposures ...

The Genomics Revolution in Nonmodel Species: Predictions vs. Reality for Salmonids. [PDF]

Mol Ecol
ABSTRACT The increasing feasibility of whole‐genome sequencing has been highly anticipated, promising to transform our understanding of the biology of nonmodel species. Notably, dramatic cost reductions beginning around 2007 with the advent of high‐throughput sequencing inspired publications heralding the ‘genomics revolution’, with predictions about ...

Estimation of Parental Abundance Using Hierarchical Bayesian Modeling With Data Augmentation. [PDF]

Ecol Evol
Pedigree accumulation estimators leverage the fact that each offspring in a cohort is genotypically “marked” by its parents and represent a recent and promising toolset for estimating population dynamics. We developed a hierarchical Bayesian pedigree accumulation estimator and compared it to previously evaluated non‐parametric approaches.
