Ecology

Description:Understanding factors regulating populations is a fundamental goal of population ecology. Life-history traits such as survival and fecundity are key vital rates responsible for population change and may vary across elevational gradients. At the upper end of this gradient, the alpine zone, populations are faced with extremely short growing seasons, unpredictable winter conditions dictated by snowpack, and the continued threat of habitat loss due to temperatures increasing beyond the range that defines these cold systems. To date, few studies have addressed population regulation of alpine-endemic species in the context of the aforementioned factors. I used long-term demographic data collected over a 51-year period at two study sites (Mt. Evans and Trail Ridge) together with a contemporary field study (2013- 2015) at three sites (Mt. Evans, Trail Ridge, and Mesa Seco) to examine factors regulating alpine-endemic white-tailed ptarmigan (Lagopus leucura) in Colorado. [show more]

Viral spread
Host-pathogen interaction

Description:Urban expansion can fundamentally alter wildlife movement and gene flow, but how urbanization alters pathogen spread is poorly understood. Here, we combine high resolution host and viral genomic data with landscape variables to examine the context of viral spread in puma (Puma concolor) from two contrasting regions: one bounded by the wildland urban interface (WUI) and one unbounded with minimal anthropogenic development (UB). We found landscape variables and host gene flow explained significant amounts of variation of feline immunodeficiency virus (FIV) spread in the WUI, but not in the unbounded region. The most important predictors of viral spread also differed; host spatial proximity, host relatedness, and mountain ranges played a role in FIV spread in the WUI, whereas roads might have facilitated viral spread in the unbounded region. Our research demonstrates how anthropogenic landscapes can alter pathogen spread, providing a more nuanced understanding of host-pathogen relationships to inform disease ecology in free-ranging species.

Subject:Whitewater parks

Description:Colorado Parks and Wildlife’s (CPW) statutory mission is to perpetuate the wildlife resources of the State, to provide a quality State Parks system, and to provide enjoyable and sustainable outdoor recreation opportunities that educate and inspire current and future generations to serve as strategic stewards of Colorado’s natural resources (C.R.S. § 33-9-101 (12) (b)). As CPW is responsible for the management and conservation of aquatic resources within the State, we are asked to review projects that may affect aquatic habitats or populations. Specifically, CPW staff is often engaged by the Army Corps of Engineers (USACE) to review permit applications related to the design, construction, and monitoring of whitewater parks (WWPs) regulated under Section 404 of the Clean Water Act. WWP projects typically fall under the following permits:

• NWP 27 - Aquatic Habitat Restoration, Establishment, and Enhancement Activities
• IP - An individual, or standard permit, is issued when projects have more than minimal individual or cumulative impacts, are evaluated using additional environmental criteria, and involve a more comprehensive public interest review.

Subject:Whitewater parks

Description:With over 30 whitewater parks (WWPs) either completed or in the planning phases, Colorado is the epicenter for WWP development in the United States. Although WWPs provide economic and recreational benefits for local communities (Hagenstad et al. 2000; Loomis and McTernan 2011), they may have unintended impacts on instream biota and stream functions, particularly when the hydraulic conditions formed by the WWP are different from those naturally found in the surrounding river. The impact of WWPs on habitat connectivity and instream habitat quality have been the focus of several recent studies. Although these studies have primarily focused on fish passage and habitat, impacts to aquatic insects and sediment transport may also occur at WWPs. [show more]
