Sleep appears to be a biological requirement for all animals except for basal species with no brain or only a rudimentary brain. It has been observed in mammals, birds, reptiles, amphibians, fish, and, in some form, in insects. The internal circadian clock promotes sleep at night for diurnal organisms (such as humans) and in the day for ...
e. Insect winter ecology describes the overwinter survival strategies of insects, which are in many respects more similar to those of plants than to many other animals, such as mammals and birds. Unlike those animals, which can generate their own heat internally (endothermic), insects must rely on external sources to provide their heat ...
Aestivation (Latin: aestas (summer); also spelled estivation in American English) is a state of animal dormancy, similar to hibernation, although taking place in the summer rather than the winter. Aestivation is characterized by inactivity and a lowered metabolic rate, that is entered in response to high temperatures and arid conditions. [1]
An insect 's respiratory system is the system with which it introduces respiratory gases to its interior and performs gas exchange. Air enters the respiratory systems of insects through a series of external openings called spiracles. These external openings, which act as muscular valves in some insects, lead to the internal respiratory system ...
Hibernation. Hibernation is a state of minimal activity and metabolic depression undergone by some animal species. Hibernation is a seasonal heterothermy characterized by low body-temperature, slow breathing and heart-rate, and low metabolic rate. It is most commonly used to pass through winter months – called overwintering.
Relatively common [6] Bed bugs are parasitic insects from the genus Cimex, who are micropredators that feed on blood, usually at night. [7] Their bites can result in a number of health impacts, including skin rashes, psychological effects, and allergic symptoms. [5] Bed bug bites may lead to skin changes ranging from small areas of redness to ...
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 timing of activity by an animal depends on a variety of environmental factors such as the temperature, the ability to gather food ...
Sleep. Developmental biology. v. t. e. In animal dormancy, diapause is the delay in development in response to regular and recurring periods of adverse environmental conditions. [1][2] It is a physiological state with very specific initiating and inhibiting conditions. The mechanism is a means of surviving predictable, unfavorable environmental ...
