Thermal Homeostasis
Why is temperature important?



Temperature affects the rates of biophysical processes
Temperature also contributes to the state and colour of something
...


Temperature vs heat


Temperature refers to the intensity of molecular motion
...


Heat transfer





Conduction – transfer of heat between objects in contact with each other through
microscopic movement
...
(Requires the convection coefficient)
...

Radiation – the transfer of heat between objects at the speed of light without the need of a
transfer medium
...
(StefanBoltzmann equation)
Metabolic processes are inefficient and lose energy through the form of heat
...
The exchange of heat with the ground is very important in terms
of heat loss and heat gain
...




Does the animal maintain its own temperature, or does it depend on the environment
...
However, only certain animals can
thermoregulate using physiological means (homeotherms)
...

Some species will do this continuously to boost heat

Behavioural thermoregulation




Dung beetles do this
...

These behaviours can include basking, shivering and moving in and out of the sun
...

Species with narrow ranges of temperature are called stenothermal
