For example, plants follow rules evolved by their diurnal and nocturnal pollinators. The whole ecosystem is designed in intricate measure around these kinds of concepts. Humidity The ecosystem makes use of symbiotic activity times.Animals activity depends on many factorsĪn animal’s wakeful times can depend on many factors. This is more important when it comes to the challenge for food and hunting grounds. The lighter, warmer, and dryer environment of daytime suits many creatures, including most of the primate kingdom.īy sharing the load day and night, animals can max out their environment and occupy the same territory without the need for competition for space. Others, roughly 70%, have evolved to live and hunt in the darker, cooler, and more humid nighttime. The unique roles of each animal have evolved to ensure that they can utilize and optimize their environment and the world around them.įor this reason, some creatures take advantage of daylight hours. In general, evolution in the animal kingdom has taken place which fully takes advantage of all opportunities. Honey bees for example, are known to sleep between 5 to 8 hours per day.Why animals are active at different times, days and seasons. So they are active through the day and sleep at night. They can see toward the ultraviolet end of the light spectrum and need the light from the sun to be able to do this. This pollen and nectar is collected during the sunny daylight hours, as most bees use the sun to navigate. They are adapted for feeding on nectar and pollen, nectar is used as an energy source and pollen used primarily for protein and other nutrients. Though most bees are solitary and parasitic, there are around 400 species of Social Bees and these are grouped as the Bumble bees and Honey bees. However these little pollinators are in danger, with numbers in great decline with pesticides and agricultural products, as well as the decline in ‘wild’ areas they need for food being major threats. There are still many unclassified species therefore the total population could be even higher. There are over 20,000 species of bees in the world in nine recognised families. It is this cycle where diurnal and nocturnal animals are very different. These rhythms run in the background and are mainly affected by light and darkness, and the most commonly observed circadian rhythm is the sleep-wake cycle. They tell the body the preferred time to carry out necessary functions like cell repair too. Or when the ‘triple heater’ will kick in, or the time of day when you are most alert or your metabolic rate at a specific time. For instance, the circadian rhythm can determine when the body will start to produce more melatonin before sleep. Including patterns of sleep, wakefulness, feeding and biological cycles. Well, circadian rhythms are basically the daily (24hr) cycles that determine the lifestyle patterns of an animal. In each case, animals follow a different circadian rhythm, depending on their preference for daylight or darkness. From there, the words are simply translated into modern English. Diurnal comes from ‘diurnus’ which means day, while nocturnal comes from ‘nocturnus’ which is Latin for ‘belonging to the night’. The terms diurnal and nocturnal both have their origins in Latin.
