Trichotillomania; an animal pulling out its own fur, hair or wool, often followed by eating it. [40] Urine drinking; drinking urine. [10] Vacuum activity; innate, fixed action patterns of behaviour performed in the absence of the external stimuli that normally elicit them. [41]
The means to control locust populations is now available, but organisational, financial, and political problems may be difficult to overcome. Monitoring is the key to early detection and eradication. Ideally, a sufficient proportion of nomadic bands can be killed with insecticide before their swarming phase.
Locus of control has been linked to political ideology. In the 1972 U.S. presidential election, research of college students found that those with an internal locus of control were substantially more likely to register as a Republican, while those with an external locus of control were substantially more likely to register as a Democratic.

IED symptoms include "recurrent behavioral outbursts representing a failure to control aggressive impulses as manifested by either of the following: 1) Verbal aggression (e.g., temper tantrums, tirades, verbal arguments or fights) or physical aggression toward property, animals, or other individuals, occurring twice weekly, on average, for a ...
The H locus is a modifier locus (of the M locus) and the alleles at the H locus will determine if an animal expresses a harlequin vs merle pattern. There are two alleles that occur at the H locus: H = Harlequin (if M/-, patches of full colour and white) h = Non-harlequin (if M/-, normal expression of merle)
Behavioral plasticity is the change in an organism's behavior that results from exposure to stimuli, such as changing environmental conditions. [1] Behavior can change more rapidly in response to changes in internal or external stimuli than is the case for most morphological traits and many physiological traits.
Heider first introduced the concept of perceived 'locus of causality' to define the perception of one's environment. [2] For instance, an experience may be perceived as being caused by factors outside the person's control (external) or it may be perceived as the person's own doing (internal). These initial perceptions are called attributions. [2]
A well-documented example of polymorphism is Labrador Retriever coloring; while the coat color depends on many genes, it is clearly seen in the environment as yellow, black, and brown. Richard Dawkins in 1978 [ 3 ] and then again in his 1982 book The Extended Phenotype suggested that one can regard bird nests and other built structures such as ...
