How Honeybees Keep Their Cool
Introductions
Many species have the ability to maintain their body temperature within a narrow range, regardless of the temperature of their surroundings, these species are known as endotherms. Scientists have been studying species such as endotherms for years. Recently, scientists came about an observation. How do bees or any endothermic animal, generate the heat required to warm itself? Although Bees are invertebrates, they are one of the few of them to be an endotherm. This observation went into a series of experiments. These experiments revealed that before a bee flies it first shivers, sometimes for a few minutes. This causes a burning of glucose …show more content…
These results just led scientist to in a few other observations. For example, how the bees keep themselves from overheating. Other observations helped to lead scientists into the new hypothesis and conclusion that bees by adjusting their metabolic rates in their flight muscles, they're able to maintain their body temperature within a narrow range. Scientists Harrison from Arizona State University and H. Glenn Hall from University of Florida were the two to make these observations and put them into action. Harrison and Hall discovered that although the flying of the bees require a large mass of energy determined by wing surface, weight, and flight speed, the bees depending on the metabolism, manage to maintain homeostasis and stay airborne. These two men took action by …show more content…
Harrison and his team then measured the thorax and abdominal temperature, metabolic rate, and wingbeat frequencies. While the air temperature increased, the metabolic rates of honeybees were determined by measuring carbon dioxide emissions in bees. They measured the carbon dioxide emissions between the bees that were agitated to keep them flying and in bees that were able to fly undisturbed. Both cases showed a decrease in the metabolic rate with increasing temperatures. The next step to the experiment was to take the body temperatures with a tiny, fast- responding microprobe. The frequency of the wingbeats were determined by using microphones, digitized tape recorders, and sound-editing softwares. The wing-beat frequency part of the experiment showed a decrease with an increase in
