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.
The sense of balance or equilibrioception is the perception of balance and spatial orientation. [1] It helps prevent humans and nonhuman animals from falling over when standing or moving. Equilibrioception is the result of a number of sensory systems working together; the eyes ( visual system ), the inner ears ( vestibular system ), and the ...
The total amount of water in the body needs to be kept in balance. Fluid balance involves keeping the fluid volume stabilized, and also keeping the levels of electrolytes in the extracellular fluid stable. Fluid balance is maintained by the process of osmoregulation and by behavior.
An overstimulated animal will have a larger flight zone, for example an excited or scared animal. [22] A Cumulative Flight Zone is formed when animals move in a herd. In this situation the lead animal's and the following animals' Points of Balance, within the cumulative flight zone, must both be crossed to entice movement. [22]
These animals may become flipped over in a fight or predator attack, so the righting response is crucial for survival. To right themselves, relatively flat animals (such as beetles) heavily rely on momentum and thrust developed by moving their limbs and wings. However, the limbs of many dome-shaped tortoises are too short to be used for righting.
The presence of predators while a (prey) animal is foraging affects its behaviour. In general, foragers balance the risk of predation with their needs, thus deviating from the foraging behaviour that would be expected in the absence of predators. [11] An example of this balanced risk can be observed in the foraging behavior of A. longimana. [12]
Center of balance (COB) is a point with respect to which the object in question is balanced with respect to applied forces. In particular areas the term may have specific meaning and special discussion, and may refer to one of the following definitions: Center of mass, the most common meaning and most of other meanings are derived from it
Pugmark is the term used to refer to the footprint of most animals (especially megafauna). "Pug" means foot in Hindi [1] (Sanskrit पद् "pad"; Greek πούς "poús"). Every individual animal species has a distinct pugmark and as such this is used for identification. An image of a thylacine pugmark
