<p>Correction: A Comparison of Grizzly Bear Demographic Parameters Estimated from Non-Spatial and Spatial Open Population Capture-Recapture Models</p

Occasion specific detection probability for female and male grizzly bears.

<p>Values for non-spatial capture-recapture models (CR_<i>dedge</i>) were based on 162, 42, and 20 active traps for bear rubs, hair traps, and highway crossings respectively. Values for spatial capture-recapture (SCR) models indicate individual detection probability at a single trap in the middle of an individual’s home range centre. Detection probability varied by sex, trap type, and sampling occasion with a year. Variability in detection probability among years depended on the number of active traps (CR_<i>dedge</i> and SCR) and the distribution of traps (SCR).</p

Number of individual grizzly bears detected by trap type and year, mean number of detections per animal per year, and percent animals with greater than one detection per year.

Parameter estimates averaged from 2006–2008, 95% HPD intervals, and coefficient of variation from non-spatial (CR_<i>dedge</i>) and spatial capture-recapture (SCR) models for female, male, and combined sex models.

<p>Parameter descriptions: φ = apparent survival, <i>R</i> = per capita recruitment, λ = population growth rate, N = number of individuals, D = density per 1000 km², σ = the scale parameter for detection probability, Model Fit = Bayesian P-value where values < 0.05 or > 0.95 indicate poor fit.</p><p>Annual estimates of population parameters are provided in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0134446#pone.0134446.s004" target="_blank">S1 Table</a>.</p

Microsatellite data for 105 black bears and 134 grizzly bears detected in Banff National Park. Excel file contains 3 worksheets (description, black bear data, grizzly bear data

Estimates of realized population growth rate () and apparent survival () from Pradel open population models for grizzly bears in the Bow Valley of Banff National Park, Alberta, Canada, between 2006 and 2008, sampled using bear rub surveys.

*<p>Our models did not vary with time; therefore they produced identical estimates for 2006–2007 and 2007–2008.</p
