Effects of snowmobile noise and activity on a boreal ecosystem in Southcentral Alaska
Dissertation (Ph.D.) University of Alaska Fairbanks, 2014 Snowmobiling is a popular winter activity in northern regions of North America. Although snowmobiles are important utility vehicles and serve as a means of outdoor recreation, their activity is known to affect plants and animals. These effect...
