Animals at the extremes: hibernation and torpor

...carbon dioxide concentration of the inhaled air is increased, then hibernating mammals react by increasing their breathing rate. In the hedgehog, the CO2 threshold is 0.7–1.7%, at which point the periods of apnoea become shorter. Continuous breathing replaces periodic breathing at 5–9% CO2. The evidence suggests therefore, that the hibernator is sensitive to changes...

...Footprints from prehistoric human civilisations around the world have been found preserved in either sand or volcanic ash. From these tracks, it is possible to measure the foot length and the length of the stride. These measurements can be used to estimate both the height of the person who made the footprint and also whether the person was walking or running. This can be...

...carbon dioxide (the main 'greenhouse gas') in the Earth's atmosphere is increasing and increasing the 'greenhouse effect' (i.e. heat is trapped by the atmosphere in the same way that heat in a greenhouse is trapped by the glass). Why is the amount of carbon dioxide increasing? Because of human activity such as burning fossil fuels, and also the destruction of rainforest...
