<em>Puma concolor</em>
Description:We examined the genetic structure of 5 Wyoming cougar (Puma concolor) populations surrounding the Wyoming Basin, as well as a population from southwestern Colorado. When using 9 microsatellite DNA loci, observed heterozygosity was similar among populations (Ho = 0.49–0.59) and intermediate to that of other large carnivores. Estimates of genetic structure (FSt = 0.028, RSt = 0.029) and number of migrants per generation (Nm) suggested high gene flow. Nm was lowest between distant populations and highest among adjacent populations. Examination of these data, plus Mantel test results of genetic versus geographic distance (P ≤ 0.01), suggested both isolation by distance and an effect of habitat matrix. Bayesian assignment to population based on individual genotypes showed that cougars in this region were best described as a single panmictic population. Total effective population size for cougars in this region ranged from 1,797 to 4,532 depending on mutation model and analytical method used. Based on measures of gene flow, extinction risk in the near future appears low. We found no support for the existence of metapopulation structure among cougars in this region. [show more]

Project Status

Ongoing

Research Objectives

  • Evaluate genetic changes over time in rainbow trout populations established using whirling disease resistant rainbow trout.

Project Description

Rainbow trout populations across the state have been re-established within the last decade using whirling disease resistant rainbow trout strains. Management changes from water to water, with different strains being stocked for different management purposes. Additionally, the size of fish stocked can differ among waters or years dependent upon management goals.

As these rainbow trout strains become established and start reproducing naturally, outcrossing and backcrossing can occur. Outcrossing can also occur in the hatchery as a result of maintaining crosses of wild and whirling disease resistant rainbow trout strains as opposed to the pure strains. Outcrossing and backcrossing can result in differential expression of the genes controlling for resistance to whirling disease through selection in both hatcheries and in the wild, and could result in loss of resistance over time.

This study is designed to look at the genetic composition of wild whirling disease resistant rainbow trout populations across years since they were established. Using stocking records to determine parental origin of wild fish, and collecting genetics from both the adult spawning population and age-0 fish naturally produced in the wild, researchers will be able to determine how different management strategies affect the genetics of these populations. Additionally, disease information collected from these same individuals will be used to determine if whirling disease resistant characteristics are changing or being maintained in these populations.

This study focuses primarily on the wild rainbow trout populations in the Colorado and Gunnison Rivers, although samples collected from other river systems will help elucidate trends statewide. This is a collaborative project between Colorado Parks and Wildlife, Colorado State University, and the University of California Davis.​

Description:Abstract: Methods for population estimation and inference have evolved over the past decade to allow for the incorporation of spatial information when using capture–recapture study designs. Traditional approaches to specifying spatial capture–recapture (SCR) models often rely on an individual-based detection function that decays as a detection location is farther from an individual’s activity center. Traditional SCR models are intuitive because they incorporate mechanisms of animal space use based on their assumptions about activity centers. We modify the SCR model to accommodate a wide range of space use patterns, including for those individuals that may exhibit traditional elliptical utilization distributions. Our approach uses underlying Gaussian processes to characterize the space use of individuals. This allows us to account for multimodal and other complex space use patterns that may arise due to movement. We refer to this class of models as geostatistical capture–recapture (GCR) models. We adapt a recursive computing strategy to fit GCR models to data in stages, some of which can be parallelized. This technique facilitates implementation and leverages modern multicore and distributed computing environments. We demonstrate the application of GCR models by analyzing both simulated data and a data set involving capture histories of snowshoe hares in central Colorado, USA. [show more]
