Summary

  1. Power analysis is an important step in designing effective monitoring programs to detect trends in plant or animal populations. Although project goals often focus on detecting changes in population abundance, logistical constraints may require data collection on population indices, such as detection/non-detection data for occupancy estimation.
  2. We describe the open-source R package, rSPACE, for implementing a spatially based power analysis for designing monitoring programs. This method incorporates information on species biology and habitat to parameterize a spatially explicit population simulation. A sampling design can then be implemented to create replicate encounter histories which are subsampled and analysed to estimate the power of the monitoring program to detect changes in population abundance over time, using occupancy as a surrogate.
  3. The proposed method and software are demonstrated with an analysis of wolverine monitoring in a U.S. Northern Rocky Mountain landscape.
  4. The package will be of use to ecologists interested in evaluating objectives and performance of monitoring programs.

Sarcoptic mange
Description:Population genetic theory posits that molecular variation buffers against disease risk. Although this “monoculture effect” is well supported in agricultural settings, its applicability to wildlife populations remains in question. In the present study, we examined the genomics underlying individual-level disease severity and population-level consequences of sarcoptic mange infection in a wild population of canids. Using gray wolves (Canis lupus) reintroduced to Yellowstone National Park (YNP) as our focal system, we leveraged 25 years of observational data and biobanked blood and tissue to genotype 76,859 loci in over 400 wolves. At the individual level, we reported an inverse relationship between host genomic variation and infection severity. We additionally identified 410 loci significantly associated with mange severity, with annotations related to inflammation, immunity, and skin barrier integrity and disorders. We contextualized results within environmental, demographic, and behavioral variables, and confirmed that genetic variation was predictive of infection severity. At the population level, we reported decreased genome-wide variation since the initial gray wolf reintroduction event and identified evidence of selection acting against alleles associated with mange infection severity. We concluded that genomic variation plays an important role in disease severity in YNP wolves. This role scales from individual to population levels, and includes patterns of genome-wide variation in support of the monoculture effect and specific loci associated with the complex mange phenotype. Results yielded system-specific insights, while also highlighting the relevance of genomic analyses to wildlife disease ecology, evolution, and conservation. [show more]
Description:Learn More: https://cpw.state.co.us/learn/Pages/ResearchBorealToad.aspx The boreal toad is one of Colorado's most endangered amphibians. Colorado Parks and Wildlife (CPW) is working to restore the small toads through an aggressive reintroduction program. To date, Zimmerman Lake in Larimer County is the only location where the small toads have established a self-sustaining population. Each year, biologists collect toad eggs at Zimmerman Lake, transport them to hatcheries and then restock the boreal tadpoles in key areas across the state. On Aug. 11, 2020, biologists stocked tadpoles into Rocky Mountain National Park in the hope of establishing a new population. CPW is working in collaboration with the National Park Service and other state and federal agencies to re-establish boreal toads across the state. The hope is that some toads will develop a resistance to the chytrid fungus, which is responsible for decimating amphibians throughout North America. Video produced by Jerry Neal/CPW [show more]

Description:Co-host Anders Halverson talks with Dr. Kevin Rogers about efforts to save the Greenback Cutthroat Trout on Colorado’s Eastern Slope. Think of it as story the producers of CSI Miami would write, if they were fortunate enough to be fisheries biologists. There’s extinction (or maybe not?). There’s resurrection (twice!). Just when you think you have it figured out, another clue from a dusty library or a PCR machine sends you off in an entirely different direction. And of course, it ends on a cliffhanger. [show more]
Description:Colorado Parks and Wildlife (CPW) has an in-house science program that has served the agency for over seven decades. CPW research scientists investigate high-priority information needs, and develop and refine many of the tools and practices our agency uses to conserve and manage Colorado’s fish, wildlife, and park resources for current and future generations. The annual Science Application Highlights briefly describes a few examples of CPW’s science activities and their application to management during the previous year. [show more]

Description:Divers can unintentionally spread freshwater aquatic nuisance species (ANS) such as the zebra or quagga mussel, New Zealand Mudsnail (NZMS), Eurasian watermilfoil, spiny water flea, or Asian clam from one body of water to another on their scuba diving gear. Some ANS larvae are invisible to the naked eye and can survive hours to weeks on wet scuba gear or in water inside equipment. By adhering to the following guidelines, you can help prevent the spread of ANS when you scuba dive. Print copy, CPW Library: FILE Scu [show more]

Winter recreation
Description:Winter recreation is a widely popular activity and is expected to increase due to changes in recreation technology and human population growth. Wildlife are frequently negatively impacted by winter recreation, however, through displacement from habitat, alteration of activity patterns, or changes in movement behavior. We studied impacts of dispersed and developed winter recreation on Canada lynx (Lynx canadensis) at their southwestern range periphery in Colorado, USA. We used GPS collars to track movements of 18 adult lynx over 4 years, coupled with GPS devices that logged 2,839 unique recreation tracks to provide a detailed spatial estimate of recreation intensity. We assessed changes in lynx spatial and temporal patterns in response to motorized and nonmotorized recreation, as well as differences in movement rate and path tortuosity. We found that lynx decreased their movement rate in areas with high-intensity back-country skiing and snowmobiling, and adjusted their temporal patterns so that they were more active at night in areas with high-intensity recreation. We did not find consistent evidence of spatial avoidance of recreation: lynx exhibited some avoidance of areas with motorized recreation, but selected areas in close proximity to nonmotorized recreation trails. Lynx appeared to avoid high-intensity developed ski resorts, however, especially when recreation was most intense. We conclude that lynx in our study areas did not exhibit strong negative responses to dispersed recreation, but instead altered their behavior and temporal patterns in a nuanced response to recreation, perhaps to decrease direct interactions with recreationists. However, based on observed avoidance of developed recreation, there may be a threshold of human disturbance above which lynx cannot coexist with winter recreation. [show more]
