“…However, pronghorn appeared to select for crossing roads during daylight hours but selected against crossing roads during nighttime in both seasons. It is possible that pronghorn may avoid crossing roads at night, when there is an increased risk for wildlife-vehicle collision (Mastro et al 2010, Diaz-Varela et al 2011, Hothorn et al 2015, but this result may also be reflective of the decreased pronghorn movement we observed during nighttime hours in summer and winter.…”

Pronghorn (Antilocapra americana) are endemic to western North America where they occupy expanses of grassland and sagebrush (Artemisia spp.) habitats. The Red Desert region in south‐central Wyoming, USA, has historically served as a stronghold for pronghorn populations, but many herds there have experienced declining population trends over the last two decades, concurrent with oil and natural gas development. These demographic changes and the potential for such energy development, its associated infrastructure, and other anthropogenic features including roads and fences to influence pronghorn habitat selection were the impetuses for our study. We sought to evaluate the potential effect of human‐induced disturbance on multi‐scale seasonal resource selection of 142 adult female pronghorn from 2013 to 2016 using 442 unique animal‐season‐year datasets. We utilized a traditional resource selection function to evaluate seasonal home‐range selection and a step‐selection function to assess fine‐scale, patch‐level seasonal selection. We also compared resource selection during daytime and nighttime hours with step‐selection analyses. At the seasonal home‐range scale, pronghorn selected for areas with more sagebrush during both seasons and areas farther from fences during summer. This trend was also apparent at the patch‐scale level, where pronghorn selected sagebrush‐dominant habitats and avoided crossing fences in all seasons during both day and night. Additionally at this scale, pronghorn selected areas farther from fences during daytime in summer. At the broader, home‐range scale, pronghorn selected areas with greater road density during summer, but with lower road densities and farther from wells during winter. Avoidance of anthropogenic features during winter was also observed at the finer, patch‐scale, with pronghorn selecting for increased density of roads and oil and natural gas wells during daytime in summer, but selecting areas farther from these features during daytime in winter. We recommend minimizing fencing and other forms of anthropogenic disturbance in high‐quality seasonal pronghorn habitats with high proportions of sagebrush, particularly during winter when risk‐avoidance responses may be amplified.

“…For example, visibility of the road verge and the immediate road ahead is known to contribute to the detectability of animals at the roadside (Mastro et al 2010). Sharp bends or corners in the road may reduce the driver's ability to view the road immediately ahead, and therefore result in potential hotspots for road-kill (Lee et al 2004;Klöcker et al 2006).…”

Abstract. Understanding the impacts of roads on wildlife and the natural environment is of increasing importance. Macropods (mostly kangaroos and wallabies) are a diverse and widespread taxon in Australia that has been significantly affected by the presence of roads in various ways. We reviewed the available literature on macropods and roads, assessing 60 scientific journal articles, reports and theses. Studies on road mortalities were the most prevalent (n = 29, with 12 on macropods only), revealing both spatial and temporal patterns in occurrence. Behavioural studies in relation to the road environment are limited (n = 2) yet could help our understanding of patterns of road-kill and other impacts. Some macropod populations are critically affected by the presence of roads (e.g. brush-tailed rock-wallaby, Petrogale penicillata) due to either proportionately high road mortalities and/or population fragmentation, and may face continued decline unless effective road-mitigation measures are implemented. Investigations of various types of road mitigation focussed on wildlife-exclusion fencing and road crossing structures as the most effective option, although the high cost of these measures appears to limit their implementation. Further research into several areas was identified, particularly on species where severe road impacts are likely to result in population declines.

“…The lower road density and higher speeds occurred at the outskirts of the city and were associated with higher deer densities. Mastro et al () found that most motorists were not able to see a deer decoy at night until they were within 50 m of it. Therefore slowing driver speed is critical for seeing and reacting to potential deer on the highway.…”

Spatial and temporal relationships between deer harvest and deer-vehicle collisions at Oak Ridge Reservation, Tennessee

White-tailed deer (Odocoileus virginianus)-vehicle collisions (DVCs) are increasing as human and deer populations continue to grow. Deer harvest was implemented at Oak Ridge Reservation, Tennessee (ORR) in 1985 to reduce DVCs. We assessed the relationship between DVCs at ORR to deer harvest, road type, and habitat features (forest, field, water, and developed cover types) during 1986-2008 using Poisson regression analysis and Akaike Information Criterion modeling. We also evaluated DVC numbers for the city of Oak Ridge and ORR during 1975-2008 Higher traffic volume and speed were positively related to DVCs. There was no effect of moon phase for all records combined; however, analysis by season and gender showed a positive relationship to collisions for male deer during the gestation period
