Ecological investigations of grizzly bears in Canada using DNA from hair, 1995–2005: a review of methods and progress (2010, methodology): “We adjusted our sampling intensity approach over the years, initially using 64 km2 cells with sampling stations moved to different sites within cells during each of 4 or 5 sampling sessions (Woods et al. 1999, Mowat and Strobeck 2000).”
A review of methods to estimate the abundance of terrestrial carnivores using field signs and observation (2001, background): “The greater the genetic variation in the population the fewer different microsatellite profiles are required to positively identify individuals (Mowat and Strobeck 2000).”
Monitoring of grizzly bear population trends and demography using DNA mark-recapture methods in the Owikeno Lake area of British Columbia (2004, methodology): “Recently, DNA mark–recapture methods have been used to estimate population size based on intensive sampling of small study areas within a single year (Woods et al. 1999; Mowat and Strobeck 2000; Poole et al. 2001; Boulanger et al. 2002).”
Evaluating the potential biases in carnivore capture–recapture studies associated with the use of lure and varying density estimation techniques using photographic-sampling data of the Malagasy civet (2011, background): “However, attractants may also introduce bias to the density estimate, irrespective of, or in combination with, the edge effect (Mowat and Strobeck 2000; Gardner et al. 2010b), by disrupting natural spatial and temporal movement patterns within the sampling area, ‘‘pulling’’ animals onto the…”
Demographic monitoring of an entire species (the northern hairy‐nosed wombat, Lasiorhinus krefftii) by genetic analysis of non‐invasively collected material (2003, methodology): “This sampling method can be used in a mark–recapture experiment to estimate the size of the wombat population (Palsbøll et al., 1997; Kohn et al., 1999; Woods et al., 1999; Mowat & Strobeck, 2000).”
Gender-specific dispersal distances of grizzly bears estimated by genetic analysis (2004, background): “Some samples came from previous DNA-based population surveys (Gibeau and Herrero 1997; Woods et al. 1999; Mowat and Strobeck 2000; Boulanger 2001; Boulanger et al. 2004).”
Carnivory is Positively Correlated with Latitude among Omnivorous Mammals: Evidence from Brown Bears, Badgers and Pine Martens (2009, methodology): “Most brown bear hair samples were collected from within the study area in 2000–2004 using a standard semi-invasive DNA hair-sampling method (Woods et al. 1996, Mowat & Strobeck 2000).”
NONINVASIVE GENETIC SAMPLING TOOLS FOR WILDLIFE BIOLOGISTS: A REVIEW OF APPLICATIONS AND RECOMMENDATIONS FOR ACCURATE DATA COLLECTION (2005, methodology): “Throughout North America, a mtDNA fragment analysis method has been used to differentiate brown bears and black bears ( Ursus americanus) from hair and fecal samples (Woods et al. 1999, Mowat and Strobeck 2000, Murphy et al. 2000, Poole et al. 2001).”
Noninvasive population genetics: a review of sample source, diet, fragment length and microsatellite motif effects on amplification success and genotyping error rates (2006, background): “Shed hair are collected in the field either opportunistically (Vigilant et al. 2001) or using hair-traps (Mowat and Strobeck 2000; Sloane et al. 2000), and DNA is generally extracted from a single hair (e.g. Sloane et al. 2000) or from very few hair (1 to 3 hair: Constable et al. 2001) to avoid…”
Grizzly Ursus arctos and black bear U. americanus densities in the interior mountains of North America (2005, methodology): “When model choice was uncertain, we used the simulation routine in CAPTURE to compare the performance of the candidate models to aid model selection (Mowat & Strobeck 2000).”
DNA-based population estimate for grizzly bears Ursus arctos in northeastern British Columbia, Canada (2001, methodology): “The mound was placed in the middle of a perimeter fence of 20-30 m of barbed wire running around three or more trees at about 50 cm from the ground (Woods et al. 1999, Mowat & Strobeck 2000).”
On the origin of faeces: morphological versus molecular methods for surveying rare carnivores from their scats (2002, background): “Other recent studies have begun to use data from microsatellites to count and track individuals (Kohn et al., 1999; Ernest et al., 2000; Mowat & Strobeck, 2000).”
A Comparison of Survey Methods for Detecting Bobcats (2006, background): “Hair-snares are scented devices upon which animals deposit hair (McDaniel et al. 2000, Mowat and Strobeck 2000).”
SOURCES OF HETEROGENEITY BIAS WHEN DNA MARK-RECAPTURE SAMPLING METHODS ARE APPLIED TO GRIZZLY BEAR (URSUS ARCTOS) POPULATIONS (2004, methodology): “Once collected, hair was genotyped using methods described in Woods et al. (1999) and Mowat and Strobeck (2000).”
Piloting a Non-Invasive Genetic Sampling Method for Evaluating Population-Level Benefits of Wildlife Crossing Structures (2010, background): “This sampling approach has proven particularly effective for wide-ranging terrestrial carnivores (Woods et al. 1999, Mowat and Strobeck 2000, Schwartz et al. 2003) and has been used to estimate grizzly bear population size (Boulanger et al. 2002), model population density and distribution (Apps et…”
USE OF POPULATION VIABILITY ANALYSIS AND RESERVE SELECTION ALGORITHMS IN REGIONAL CONSERVATION PLANS (2003, methodology): “We used regional-scale survey data for black bear (Mowat and Strobeck 2000) to create an empirical model for that species (Carroll et al. 2002).”
Extinction Debt of Protected Areas in Developing Landscapes (2004, background): “…occurrence of the two carnivore species rather than field data on distribution because our SEPM results closely matched the observed distribution (Mowat & Strobeck 2000; Mattson & Merrill 2002) and allowed us to assess the long-term ability of a park to support the species—the equilibrium…”
