Many metrics exist for quantifying the relative value of habitats and pathways used by highly mobile species. Properly selecting and applying such metrics requires substantial background in mathematics and understanding the relevant management arena. To address this multidimensional challenge, we demonstrate and compare three measurements of habitat quality: graph-, occupancy-,...

Use of real-time dust monitoring and surface condition to evaluate success of unpaved road treatments
Bethany K. Kunz, Nicholas S. Green, Janice L. Albers, Mark L. Wildhaber, Edward E. Little
2018, Transportation Research Record (2672) 195-204
Fugitive dust from unpaved roads creates human health hazards, degrades road surfaces, and increases the cost of road maintenance. As a result, many different chemical treatments are applied to unpaved roads in an attempt to control dust and stabilize the wearing course. However, investigations of the effectiveness of these treatments...
River otter distribution in Nebraska
N. R. Bieber, S. P. Wilson, Craig R. Allen
2018, Wildlife Society Bulletin (42) 136-143
The river otter (Lontra canadensis) was extirpated from Nebraska, USA, in the early 1900s and reintroduced starting in 1986. Information is needed regarding the distribution of river otters in Nebraska before decisions can be made regarding its conservation status. Understanding distribution of a species is critically important for effective management....

Craig R. Allen, Hannah E. Birge, David G. Angeler, Craig Anthony Arnold, Brian C. Chaffin, Daniel A. DeCaro, Ahjond S. Garmestani, Lance Gunderson
2018, Ecology and Society (1)
Several frameworks have been developed to assess the resilience of social-ecological systems, but most require substantial data inputs, time, and technical expertise. Stakeholders and practitioners often lack the resources for such intensive efforts. Furthermore, most end with problem framing and fail to explicitly address trade-offs and uncertainty. To remedy this...
