Male Canadian garter snakes huddle around a female after hibernation when mating.. Huddling confers higher and more constant body temperatures than solitary resting. [3] Some species of ectotherms including lizards [4] and snakes, such as boa constrictors [5] and tiger snakes, [6] increase their effective mass by clustering tightly together.
The balance of nature, also known as ecological balance, is a theory that proposes that ecological systems are usually in a stable equilibrium or homeostasis, which is to say that a small change (the size of a particular population, for example) will be corrected by some negative feedback that will bring the parameter back to its original "point of balance" with the rest of the system.
In biochemistry, steady state refers to the maintenance of constant internal concentrations of molecules and ions in the cells and organs of living systems. [1] Living organisms remain at a dynamic steady state where their internal composition at both cellular and gross levels are relatively constant, but different from equilibrium concentrations. [1]
Using satellite images, researchers have created a new real-time mapping system for tiger habitats that could aid in conservation efforts. How NASA and Google Earth are helping save tigers Skip to ...
When the core body temperature drops, the shivering reflex is triggered to maintain homeostasis. Skeletal muscles begin to shake in small movements, creating warmth by expending energy. Shivering can also be a response to fever, as a person may feel cold. During fever, the hypothalamic set point for temperature is raised.
Developmental homeostasis is a process in which animals develop more or less normally, despite defective genes and deficient environments. [1] It is an organism's ability to overcome certain circumstances in order to develop normally. This can be a circumstance that interferes with either a physical or mental trait.
The tiger is popularly thought to be the largest living felid species; but since tigers of the different subspecies and populations vary greatly in size and weight, the tiger's average size may be less than the lion's, while the largest tigers are bigger than their lion counterparts.
Thermoregulation is the ability of an organism to keep its body temperature within certain boundaries, even when the surrounding temperature is very different. A thermoconforming organism, by contrast, simply adopts the surrounding temperature as its own body temperature, thus avoiding the need for internal thermoregulation.
