Data Usage Summary
  • Data Use Policy

    1. Use our data freely. All Niwot LTER data products (except some recent data sets for which metadata but not data are available) are released to the public and may be freely copied, distributed, edited, remixed, and built upon under the condition that you provide acknowledgement as described below.

    2. Give proper acknowledgement. Publications, models and data products that make use of these data sets must include proper acknowledgement, including citing data sets in a similar way to citing a journal article. See http://www.datacite.org/whycitedata). The following acknowledgment should accompany any publication or citation of these data: Logistical support and/or data were provided by the NSF supported Niwot Ridge Long-Term Ecological Research project and the University of Colorado Mountain Research Station

    3. Let us know how you will use the data. The data set creators and Niwot LTER would appreciate hearing of any plans to use the data set. Consider consultation or collaboration with data set creators.

    4. Although efforts have been made to ensure that these data are of the highest quality, the possibility of errors exists. Plase notify the data manager of any errors at lternwt@colorado.edu.

Abstract:

Pikas are captured, anesthetized, marked with colored ear-tags, non-lethally sampled, and released at point of capture during June-October. Study sites include a gradient of elevation and slope aspect, allowing a comparative study of pika response to variation in climate and sub-surface microclimate. Daily variation in snow cover and sub-surface temperatures are measured using data loggers placed within the territories of marked pikas. Focal territories are revisited at least once to characterize available vegetation via transect sampling and at least annually to service data loggers and record pika survival. Samples collected for genetic and physiological studies include ectoparasites, blood, saliva, urine, feces and hair as well as records of sex, stage, reproductive status, weight, foot length and body temperature.

Location:

West knoll of the saddle on Niwot Ridge, the highest site included in this study, with multiple slope aspects;
Long Lake, a north-facing site just below the lower north-facing part of the west knoll site;
Mitchell Lake, a south-facing site just above Mitchell Lake on the south slope of Mt. Audubon at an elevation similar to the Long Lake site;
Cable Gate, a south-facing site just upslope of the final parking lot on the Niwot Ridge road.
