American Pikas' (Ochotona princeps) Foraging Response to Hikers and Sensitivity to Heat in an Alpine Environment

  title={American Pikas' (Ochotona princeps) Foraging Response to Hikers and Sensitivity to Heat in an Alpine Environment},
  author={Natalie Stafl and Mary I. O’Connor},
Abstract Optimal foraging theory predicts tradeoffs in animals balancing net energy intake and predator avoidance. In particular, overall foraging activity could be low if (1) perception of predation risk is high or (2) abiotic conditions are suboptimal. American pikas (Ochotona princeps) are small, food-hoarding mammals whose foraging opportunities are restricted by heat and risk of predation. If hiking disturbance is perceived by pikas as predation risk, it could reduce the amount of food… 
Signatures of adaptive molecular evolution in American pikas (Ochotona princeps)
The American pika (Ochotona princeps) is a small, winter-active mammal inhabiting alpine environments. For alpine mammals, metabolic heat production and cellular mechanisms to cope with hypoxia are
Lowland biotic attrition revisited: body size and variation among climate change ‘winners’ and ‘losers’
Assessment of spatio-temporal niches of rainforest mammal species in Borneo across gradients in elevation and temperature suggests body mass may be a key ecological trait influencing the identity of climate change winners and losers.
Evaluating mechanisms of plant‐mediated effects on herbivore persistence and occupancy across an ecoregion
The results both identify important aspects of vegetation communities that may influence herbivore distribution in mountainous areas across a large, diverse geographic region, and contribute to an improved understanding of how mountain ecosystems may be affected by ongoing climate change, more broadly.
Camera Traps Provide Insights into American Pika Site Occupancy, Behavior, Thermal Relations, and Associated Wildlife Diversity
Abstract. Custom camera traps were positioned at American pika (Ochotona princeps) haypiles in 12 warm, low-elevation locations of eastern California over 5 years and during warm and cold seasons.
Life in fluctuating environments
This work provides a framework describing how feedback and feedforward mechanisms operating within organisms can generate effects across scales of organization, and how they allow living systems to persist in fluctuating environments.


Forage selection by collared pikas, Ochotona collaris, under varying degrees of predation risk
The reasons for increased preference for poorer quality forage species in 2002 relative to 2000 are currently unknown but may reflect changes in predator abundance, forage quality, or increased competition for limited forage resources.
Foraging Behavior of the Pika (Ochotona princeps), with Comparisons of Grazing versus Haying
Differences between grazing (direct consumption of plants) and haying (harvesting and caching plants) behaviors appear to reflect differences in costs and benefits between these activities.
Abstract We conducted exploratory analyses to examine the relative roles played by natural and anthropogenic influences on persistence of a montane mammal. We revisited historical locations of pikas
Effects of tourists on behavior and demography of Olympic marmots.
The supposition that marmots can adjust their behavior to avoid negative demographic consequences when confronted with heavy tourism has been based on potentially ambiguous behavioral data, and the results support this hypothesis and demonstrate the importance of considering demographic data when evaluating the impacts of recreation on animal populations.
The Function of Haypiles of Pikas (Ochotona princeps)
The pika, Ochotona princeps , spends a considerable amount of time during summer caching vegetation. These caches (haypiles) have been suggested to function as the mainstay of diet in winter, as a
Synthesis Human-caused Disturbance Stimuli as a Form of Predation Risk
This work discusses why, from an evolutionary perspective, disturbance stimuli should be analogous to predation risk, and considers disturbance effects on the behavior of individuals—vigilance, fleeing, habitat selection, mating displays, and parental investment—as well as indirect effects on populations and communities.
American Pikas (Ochotona princeps) in Northwestern Nevada: A Newly Discovered Population at a Low-elevation Site
Results presented here further illustrate that although thermal influences appear to be the single strongest determinant of pika distribution currently, such influences interact with a number of other factors to determine persistence.
The Distribution and Dispersal of Pikas: Influences of Behavior and Climate
Field experiments suggest that when pikas are deprived of the opportunity to retreat to favorable microclimates in rockslides, they are unable to tolerate the high diurnal tempera- tures found at lower elevations, and high environmental temperatures apparently constitute a major stress on dispersing individuals at low altitudes.
