资源简介:
To collect data on the temperature of the two forest areas, we used a tetrad sampling unit. This tetrad consisted of 4 agar models fitted with a 170 cm HOBO® Data Logger (U12-008) sensor programmed to record the temperature every 15 min. We placed one tetrad across 8 different replicates in a transects in each forest environment. The distance between tetrads was from 5 to 7 m, and the distance between models within a tetrad was based on sensor length (about 250 cm). We collected operational temperature data continuously over the sampling period using eight tetrads, all of which were set to collect data for five consecutive days. We sampled Wet Forest first (23 to 27 October 2016), then Transitional Forest (29 October to 2 November 2016). To collect data on body temperature and water loss of agar models, we used eight similar tetrad in the same transects explained above. However, for the behavior data, we did not use temperature sensors. Instead, we collected body temperature using a Raytek Pro Infrared Thermometer placed 2 cm above a model's surface to measure model temperature. As those behavior models were moved constantly depending on their behavior, we used a FLIR TG165 Thermal Imaging Thermometer to visualize the thermograms of the soil surface to select the Warmest Neighboring Site and Alternative Warmest Neighboring Site. For water loss measures, we weighted each model at 0600 h after measuring temperature and repeated this every two hours. We used a portable balance (A&D Newton EJ-123, 0.01g accuracy) and calculated water loss rates from the difference between the initial model mass and mass measured at each subsequent 2-hour period. We express water loss as a percentage of maximum hydration.
