  2. Insect thermoregulation - Wikipedia

    en.wikipedia.org/wiki/Insect_thermoregulation

    The pre-flight warm-up behavior of a moth. Insect thermoregulation is the process whereby insects maintain body temperatures within certain boundaries.Insects have traditionally been considered as poikilotherms (animals in which body temperature is variable and dependent on ambient temperature) as opposed to being homeothermic (animals that maintain a stable internal body temperature ...

  3. Tardigrade - Wikipedia

    en.wikipedia.org/wiki/Tardigrade

    Also in the head are two eyespots in the brain, and several sensory cirri and pairs of hollow antenna-like clavae which may be chemoreceptors. [3] The tardigrade Dactylobiotus dispar can be trained by classical conditioning to curl up into the defensive 'tun' state in response to a blue light associated with a small electric shock, an aversive ...

  4. Human thermoregulation - Wikipedia

    en.wikipedia.org/wiki/Human_thermoregulation

    Simplified control circuit of human thermoregulation. [8]The core temperature of a human is regulated and stabilized primarily by the hypothalamus, a region of the brain linking the endocrine system to the nervous system, [9] and more specifically by the anterior hypothalamic nucleus and the adjacent preoptic area regions of the hypothalamus.

  5. Hibernation - Wikipedia

    en.wikipedia.org/wiki/Hibernation

    Hibernation functions to conserve energy when sufficient food is not available. To achieve this energy saving, an endothermic animal decreases its metabolic rate and thereby its body temperature. [3] Hibernation may last days, weeks, or months—depending on the species, ambient temperature, time of year, and the individual's body-condition.

  6. Ectotherm - Wikipedia

    en.wikipedia.org/wiki/Ectotherm

    The green line represents the base temperature of the burrow. Lizards are ectotherms and use behavioral adaptations to control their temperature. They regulate their behavior based on the temperature outside; if it is warm they will go outside up to a point and return to their burrow as necessary.

  7. Insect winter ecology - Wikipedia

    en.wikipedia.org/wiki/Insect_winter_ecology

    The temperature at which an insect spontaneously freezes is referred to as the supercooling point (SCP). For freeze-avoidant insects, the SCP is thought to be equivalent to the lower lethal temperature (LLT) of the organism. [11] The freezing process is usually initiated extracellularly in the gut, tissues, or hemolymph. In order to supercool ...

  8. Predation - Wikipedia

    en.wikipedia.org/wiki/Predation

    Spider wasps paralyse and eventually kill their hosts, but are considered parasitoids, not predators.. At the most basic level, predators kill and eat other organisms. However, the concept of predation is broad, defined differently in different contexts, and includes a wide variety of feeding methods; moreover, some relationships that result in the prey's death are not necessarily called pre

  9. Persistence hunting - Wikipedia

    en.wikipedia.org/wiki/Persistence_hunting

    Persistence hunting can be done by walking, but with a 30 to 74% lower rate of success than by running or intermittent running. Furthermore, while needing 10 to 30% less energy, it takes twice as long. Walking down prey, however, might have arisen in Homo erectus, preceding endurance running. [12]
