An equilibrium glide, achieving a constant airspeed and glide angle, is harder to obtain as animal size increases. Larger animals need to glide from much higher heights and longer distances to make it energetically beneficial. [9] Gliding is also very suitable for predator avoidance, allowing for controlled targeted landings to safer areas.
In cold weather, sugar gliders will huddle together to avoid heat loss, and will enter torpor to conserve energy. [31] Huddling as an energy conserving mechanism is not as efficient as torpor. [ 31 ] Before entering torpor, a sugar glider will reduce activity and body temperature normally in order to lower energy expenditure and avoid torpor.
Feathertail gliders do not hibernate as such, but are capable of entering torpor during cold weather at any time of the year. Torpor can last for several days, during which time the animal's body temperature can drop to as low as 2 °C (36 °F) and oxygen consumption to just 1% of normal. [ 4 ]
A wheeled buffalo figurine—probably a children's toy—from Magna Graecia in archaic Greece [1]. Several organisms are capable of rolling locomotion. However, true wheels and propellers—despite their utility in human vehicles—do not play a significant role in the movement of living things (with the exception of the corkscrew-like flagella of many prokaryotes).
The two most important properties to look for in cold-weather gear are thermal insulation and wind resistance, says Khubab Shaker, chairman of the department of materials at the National Textile ...
The annual rite on Groundhog Day isn’t great at predicting the length of winter. But there are some science-based links between plants, animals and incoming weather.
