Sensor-based methods of monitoring bee colonies have been shown to detect effects of stressors, such as poor nutrition or agrochemical exposure on colony foraging activity and thermoregulation that are difficult to detect using other means, such as visual colony assessments. The work here is intended to improve and expand the application of sensor-based data to bee research. In addition to hive weight and internal temperature, other kinds of sensors, such as CO2 sensors, will be used and, if needed, new methods of analysis will be developed. In order to understand and exploit sensor data, sensor output will be related to biological and physiological metrics of sampled bees within the colony.
