Diurnal

Relating to or occurring during the daytime; active primarily during the day. This adjective describes organisms, activities, or phenomena that are synchronized with the day-night cycle, exhibiting patterns of activity and rest that are influenced by sunlight and darkness. The term often applies to animal behavior, plant processes, and even certain geological or atmospheric events that are most prominent or active during daylight hours. This cycle is contrasted with nocturnal behavior, which centers around activity during the night.

Diurnal meaning with examples

• The lion, once very busy hunting during the day has shifted to being nocturnal in regions with lots of human activity, but they're naturally a diurnal hunter. The park's wildlife viewing opportunities are often best during the early morning and late afternoon when diurnal animals are most active. Their behavior shifts based on the climate, light, and time of day.
• Farmers often schedule their work to coincide with the diurnal cycle to utilize daylight hours effectively. They will have less production or other things accomplished when working at night, since the sun's radiation cannot provide the same effects to the plants or animals. With the sun's light they are able to accomplish much more.
• Many plants, like sunflowers, exhibit diurnal movement, following the sun's trajectory across the sky. The plants will orientate in the direction of the sun when the light provides enough energy and help with the other processes necessary for survival.
• A study of the local ecosystem revealed a clear diurnal pattern of insect activity, with different species dominating during different parts of the day. Certain species will come out with enough light while others need to wait for the night.
• Meteorologists track diurnal temperature variations to understand daily weather patterns. The changes in temperature are able to signal and predict the next day's weather patterns or help with other processes that require such information.
