SDSU Beef Day 2020 Summary Publication
The ability to remotely track livestock through the use of GPS technology has tremendous potential to study livestock use patterns on the landscape. The use of high frequency accelerometers may give researchers and managers the ability to accurately partition GPS points into differing behaviors, giving further insight into livestock grazing selection, pasture use, and changes in forage preference through time. The objectives of this study were to 1) develop a classification algorithm to discriminate between graze and non-graze behaviors using a combination of metrics derived from a high frequency accelerometer motion sensor and a GPS data logger and 2) assess …
Temperature Effects On Moose (Alces Alces) Activity Patterns In Isle Royale National Park, Isabella C. Evavold
Temperature Effects On Moose (Alces Alces) Activity Patterns In Isle Royale National Park, Isabella C. Evavold
Undergraduate Theses, Professional Papers, and Capstone Artifacts
Moose (Alces alces) in Isle Royale National Park impact the ecosystem by browsing tree species and serving as the primary food source for wolves. As a heat-sensitive species, moose are susceptible to the impacts of climate change in the southern extent of their range which includes Isle Royale. Understanding how temperature impacts moose behavior is valuable and can be used to predict how moose may respond to changing temperature in the future. GPS enabled radio-collars with three-axis accelerometers were used to collect one year of temperature and activity data from 6 cow moose in Isle Royale National Park. …
