Ecology and Evolution, 2020 Close‐kin mark–recapture (CKMR) is a method for estimating abundance and vital rates from kinship relationships observed in genetic samples. CKMR inference only requires animals to be sampled once (e.g., lethally), potentially widening the scope of ...

Validation of close‐kin mark–recapture (CKMR) methods for estimating population abundance [PDF]
, 2019 1. 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 ...

Absolute abundance of southern bluefin tuna estimated by close-kin mark-recapture
Nature Communications, 2016 Accurate determination of population size for highly-mobile marine animals is often prohibitively difficult. Here, Bravingtonet al.estimate the abundance of southern bluefin tuna using a method based on the number of parent-offspring pairs detected ...

Nearly unbiased estimator of contemporary Ne/N based on kinship relationships
Ecology and Evolution, 2020 This study develops a nearly unbiased estimator of the ratio of the contemporary effective mother size to the census size in a population, as a proxy of the ratio of contemporary effective size (or effective breeding size) to census size (Ne/N or Nb/N ...

Using spatial genetics to quantify mosquito dispersal for control programs
BMC Biology, 2020 Background Hundreds of millions of people get a mosquito-borne disease every year and nearly one million die. Transmission of these infections is primarily tackled through the control of mosquito vectors. The accurate quantification of mosquito dispersal

Does Your Species Have Memory? Analysing Capture-Recapture Data with Memory Models. [PDF]
, 2014 1. We examine memory models for multi-site capture-recapture data. This is an important topic,as animals may exhibit behaviour that is more complex than simple first-order Markov movement between sites, when it is necessary to devise and fit appropriate ...

Population size estimation of swordfish through Close-Kin Mark Recapture
, 2023 International audience“Swordfish (Xiphias gladius) is managed in the Indian Ocean by the Indian Ocean Tuna Commission (IOTC) and is of special economic importance. Currently IOTC estimates the swordfish stock size using SS3 models based on CPUE which can

A non-technical overview of spatially explicit capture-recapture models [PDF]
, 2010 Most capture-recapture studies are inherently spatial in nature, with capture probabilities depending on the location of traps relative to animals. The spatial component of the studies has until recently, however, not been incorporated in statistical ...

The Swedish Arctic Fox Project: 40 years of research in ecology and conservation
The Journal of Wildlife Management, EarlyView.The 4 central research themes in The Swedish Arctic Fox Project and key deliverables for practical conservation achieved over 4 decades. Abstract The scientific community widely recognizes the value of long‐term studies, especially those with individual‐level resolution; however, maintaining a consecutive data series is associated with multiple ...
