Aestivation Aestivation Aestivation or æstivation (from , summer, but also spelled estivation in American English) is a state of animal dormancy, similar to hibernation, characterized by inactivity and a lowered metabolic rate, that is entered in response to high temperatures and arid conditions. It takes place during times of heat and dryness, the hot dry season, which are often the summer months. Invertebrate and vertebrate animals are known to enter this state to avoid damage from high temperatures and the risk of desiccation. Both terrestrial and aquatic animals undergo aestivation. The fossil record suggests that aestivation may have evolved several hundred
Fast Dormancy Fast Dormancy Fast Dormancy, or FD, is a mobile technology feature designed to reduce battery consumption and network utilization between mobile devices and their respective carrier networks during periods of data inactivity. It is currently implemented by monitoring the activity level of the mobile device and setting it to a control channel and power state appropriate for its level of activity. Each state results in different power consumption and network throughput while allowing a consistent data connection to be maintained. It is standardized by the 3rd Generation Partnership Project (3GPP) and implemented by most mobile carriers as a standard feature.
