The law of tolerance, or theory of tolerance, is best illustrated by a bell shaped curve. The range of the optimum. Tolerance ranges are not necessarily fixed. They can change as: Seasons change. Environmental conditions change. Life stage of the organism changes. Example – blue crabs. The eggs and larvae require higher salinity than adults.
A tolerance interval (TI) is a statistical interval within which, with some confidence level, a specified sampled proportion of a population falls. "More specifically, a 100×p%/100×(1−α) tolerance interval provides limits within which at least a certain proportion (p) of the population falls with a given level of confidence (1−α)."
Levels of Environmental Sensitivity often vary considerably from individual to individual, with some being more and others less sensitive to the same conditions. Such differences have been observed across many species such as pumpkinseed fish, zebra finches, mice, non-human primates and humans, indicating that there is a biological basis to ...
A specialist species can thrive only in a narrow range of environmental conditions or has a limited diet. Most organisms do not all fit neatly into either group, however. Some species are highly specialized (the most extreme case being monophagous, eating one specific type of food ), others less so, and some can tolerate many different ...
The killer ape theory or killer ape hypothesis is the theory that war and interpersonal aggression was the driving force behind human evolution.It was originated by Raymond Dart in his 1953 article "The predatory transition from ape to man"; it was developed further in African Genesis by Robert Ardrey in 1961.

Over the course of the 20th century, it became a seminal text in the field of comparative psychology, significantly influencing the study of apes. [ 3 ] [ 4 ] [ 5 ] The increased interest was "followed by nearly a century of German primate research, observations of gorillas in Germany’s sophisticated zoos, and public funding for the study of ...
However, the notion of behavior setting is offered here in more detail and with more specificity than is found in the larger entry under ecological psychology or environmental psychology. There has been a tendency in the social sciences generally to polarize arguments about consciousness, identity, behavior, and culture around either the mind ...
In ecology and genetics, a reaction norm, also called a norm of reaction, describes the pattern of phenotypic expression of a single genotype across a range of environments. One use of reaction norms is in describing how different species—especially related species—respond to varying environments.
