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 dormant data connectivity state and reduce power consumption. Beginning with Release 8.0 of Fast Dormancy, device states are used to set power consumption and data throughput during periods of inactivity. The standard device states specified by Fast Dormancy are as follows: 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
