Evaluating The Efficacy Of The Rodenatortm (Propane-Oxygen Device) For Control Of Black-Tailed Prairie Dogs In Montana, Stephen M. Vantassel
School of Natural Resources: Faculty Publications
Black-tailed prairie dogs’ feeding and burrowing behavior is a significant economic nuisance to agricultural producers. We tested the RodenatorTM on two portions of an isolated prairie dog town in Lewis and Clark County, Montana to determine how effective it was in reducing prairie dog numbers. Though other studies have been done using propane-oxygen devices, our study employed updated application techniques and an aggressive hole closing procedure to reduce the likelihood of false failures. In the southern area, we treated 53 burrows for 30 seconds with oxygen set at 40 psi and propane at 45 psi. In the northern area, we …

School of Natural Resources: Faculty Publications
With the increasing use of the term ‘‘flash drought’’ within the scientific community, Otkin et al. provide a general definition that identifies flash droughts based on their unusually rapid rate of intensification. This study presents an objective percentile-based methodology that builds upon that work by identifying flash droughts using standardized evaporative stress ratio (SESR) values and changes in SESR over some period of time. Four criteria are specified to identify flash droughts: two that emphasize the vegetative impacts of flash drought and two that focus on the rapid rate of intensification. The methodology was applied to the North American Regional …

Variation In White-Tailed Deer Antler Size: The Effects Of Age, Landscape Composition, And Physiographic Province, Kathleen B. Quebedeaux, Andrew R. Little, Nathan P. Nibbelink, Gino J. D'Angelo, Charlie H. Killmaster, Karl V. Miller
School of Natural Resources: Faculty Publications
Spatial variation in landscape composition can influence phenotypic expression in wildlife species and can improve management efforts to express certain phenotypic traits. We evaluated the influence of age, landscape composition, and physiographic province on white-tailed deer (Odocoileus virginianus) antler characteristics using data from 16,622 male deer (age range: 1.5–3.5+ years old) harvested between 1997–2016 across five physiographic provinces in Georgia. Age and physiographic province influenced antler size index (ASI; P < 0.001). ASI of yearling males was greatest (- x = 53.37; SE = 0.39) in the Upper Coastal Plain and least (- x = 46.23; SE = 0.51) in the Lower Coastal Plain physiographic province. Given the differences in ASI among physiographic provinces, we evaluated how landscape composition within each physiographic province influenced ASI of 7,325 yearling (1.5-year-old) males. Yearling ASI was positively related to increasing coverage of cultivated crops and suburban-urban areas (e.g., parks, small housing developments). Conversely, evergreen and deciduous forested cover consistently had a negative effect on ASI, except in the Ridge and Valley physiographic province where evergreen was positively related to ASI. Wildlife managers and hunters should recognize the effects of age, landscape composition, and physiographic province when setting antler size expectations.

The Adaptive Cycle: More Than A Metaphor, Shana M. Sundstrom, Craig R. Allen
School of Natural Resources: Faculty Publications
The adaptive cycle and its extension to panarchy (nested adaptive cycles) has been a useful metaphor and conceptual model for understanding long-term dynamics of change in ecological and social–ecological systems. We argue that adaptive cycles are ubiquitous in complex adaptive systems because they reflect endogenously generated dynamics as a result of processes of self-organization and evolution. We synthesize work from a wide array of fields to support this claim. If dynamics of growth, conservation, collapse and renewal are endogenous dynamics of complex adaptive systems, then there ought to be signals of system change over time that reflect this. We describe …

Chronology Of Dune Development In The White River Badlands, Northern Great Plains, Usa, P. E. Baldauf, P. A. Burkhart, Paul R. Hanson, M. Miles, Ashley Larsen
School of Natural Resources: Faculty Publications
Aeolian dune field chronologies provide important information on drought history on the Great Plains. The White River Badlands (WRB) dunes are located approximately 60 km north of the Nebraska Sand Hills (NSH), in the western section of the northern Great Plains. Clifftop dunes, sand sheets, and stabilized northwest-southeast trending parabolic dunes are found on upland mesas and buttes, locally called tables. The result of this study is a dune stabilization history determined from samples collected from stratigraphic exposures and dune crests. Thirty-seven OSL ages, from this and previous investigations, show three periods of dune activity: 1) ~21,000 years ago to …

Woolly mammoth (Mammuthus primigenius), horse (Equus spp.) and bison (Bisonspp.) coexisted with a variety of mammalian megafauna across the Pleistocene mammoth steppe e a megacontinental ecosystem that spanned northern Eurasia and northwestern North America. Previous research has suggested that highly conserved niches with minimal niche overlap allowed high levels of species diversity on the mammoth steppe. Here we evaluate previously published and some new collagen carbon and nitrogen isotope data (delta13C, delta15N) for mammoth steppe megaherbivores using Stable Isotope Bayesian Ellipses in R (SIBER) and linear regression models to determine isotopic …
