Steppe eagles are diurnal, and hunt during the day. Humans are diurnal, and organize their work and business mainly in the day. [a] Diurnality is a form of plant and animal behavior characterized by activity during daytime, with a period of sleeping or other inactivity at night. The common adjective used for daytime activity is "diurnal". The ...
Diurnal cycle, any pattern that recurs daily Diurnality, the behavior of animals and plants that are active in the daytime; Diurnal phase shift, a phase shift of electromagnetic signals; Diurnal temperature variation, a cycle of daily temperature change
A diurnal cycle (or diel cycle) is any pattern that recurs every 24 hours as a result of one full rotation of the planet Earth around its axis. [1] Earth's rotation causes surface temperature fluctuations throughout the day and night, as well as weather changes throughout the year.
Humans are normally diurnal creatures that are active in the daytime. [citation needed] As with most other diurnal animals, human activity-rest patterns are endogenously regulated by biological clocks with a circadian (~24-hour) period. [citation needed] Chronotypes have also been investigated in other species, such as fruit flies [3] and mice. [4]
The diurnal offices or daytime offices (Ecclesiastical Latin: horae diurnae) are the canonical hours during the day. Interpretation of their number and identity varies. Interpretation of their number and identity varies.
These lizards are diurnal, and are commonly seen basking on paths, rocks, and fence posts, and other suitable sunny locations. [7] They can change color from light grey or tan to nearly jet black for the purpose of thermoregulation while basking. S. occidentalis goes through a period of brumation during the winter. The length of time and when ...
Diel vertical migration (DVM), also known as diurnal vertical migration, is a pattern of movement used by some organisms, such as copepods, living in the ocean and in lakes. The adjective "diel" (IPA: / ˈ d aɪ. ə l /, / ˈ d iː. əl /) comes from Latin: diēs, lit. 'day', and refers to a 24-hour period.
In the absence of such extreme air-mass changes, diurnal temperature variations typically range from 10 °F (5.6 °C) or smaller in humid, tropical areas, up to 40 to 50 °F (22.2 to 27.8 °C) in higher-elevation, arid to semi-arid areas, such as parts of the U.S. Western states' Intermountain Plateau areas, for example Elko, Nevada, Ashton ...
