Supplement 1. Water isotope data from Konza bison project.

File List bison_data_for_supplemental.csv (MD5: 862a49c8dddac2180bc320d3647a5ea8) – Water isotope data collected from bison fecal samples, streamwater samples, and precipitation samples from Jan 2010 to March 2011 on the Konza Prairie, KS USA. Description Sample_ID_bison refers to the unique animal ID for each animal in the Konza herd Sample_date refers to the collection date of bison fecal samples Days_since_rain refers to the time (days) between sample collection and the last previous rainfall event on site Year_born refers to year of animal birth. ‘UNK’ signifies an unknown birth year Gender is animal gender Age_class refers to the animal’s age class at the date of sample collection. Location_collected refers to the Konza watershed where the sample was collected. UNK signifies that watershed ID was not recorded when collected. dD is the hydrogen isotopic ratio of the bison fecal water sample d18o is the oxygen isotopic ratio of the bison fecal water sample sample_date_stream is the date of sampling from the Konza stream ‘King’s Creek’. d18O_stream is the oxygen isotopic ratio of water from the stream dD_stream is the hydrogen isotopic ratio of water from the stream sample_date_precip is the date of sampling of precipitation from the Konza headquarters station dD_precip is the hydrogen isotopic ratio of precipitation d18O_precip is the oxygen isotopic ratio of precipitation
