Representative Tb profiles of 4 bears (3 adults A1, A2o, A3) and 1 juvenile (J1) during the week of Jan 24, 2013. Also shown for comparison are: 1) the local environmental (outdoor, To) temperatures recorded at the Pullman regional airport located 1.5 miles (2.4 km) from the WSU Bear Center (PUW; data downloaded from http://www.ncdc.noaa.gov), and 2) the indoor isolation building temperatures (Ti) for the same period. Captive bears A1, A3, J1 were housed indoors under constant conditions while bear A2o was housed under naturally fluctuating light and temperature conditions
