A major portion of humans’ activity-based energy expenditure is taken up by locomotion, particularly walking. Humans can offset the energetic expenditure of walking in numerous ways, both evolutionary (such as changes in body shape) and culturally. Behaviorally, people can choose to walk in a variety of ways, including alone or with a group, carrying loads, and walking quickly or more slowly. All of these behaviors have energetic outcomes and as such can be important windows into how populations and groups adjust to different constraints. While sex differences in speed of paired walkers have been established by others, the dynamics of …

Despite the importance of water to living organisms, access varies across the globe with high variability over space and time. Seventy-five percent of the world’s freshwater alone is ice while 99% of unfrozen freshwater is underground (Winter et al. 1998). Understanding how terrestrial species respond to water availability and compensate for water stress can provide insight to their behavior, ecology and physiology. The goal of this research was to examine the differences in the evaporative water loss rates and desiccation tolerances of Hogna carolinensis and Acheta domesticus. First, an experiment was conducted to quantify the rate of evaporative water …
