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.
Tolerance to infection, or disease tolerance, is a mechanism that host organisms can use to fight parasites or pathogens that attack the host. Tolerance is not equivalent to resistance. Disease resistance is the host trait that prevents infection or reduces the number of pathogens and parasites within or on a host.
Psychology Today content and its therapist directory are found in 20 countries worldwide. [3] Psychology Today's therapist directory is the most widely used [4] and allows users to sort therapists by location, insurance, types of therapy, price, and other characteristics.

The pygmy mammoth is an example of insular dwarfism, a case of Foster's rule, its unusually small body size an adaptation to the limited resources of its island home.. A biological rule or biological law is a generalized law, principle, or rule of thumb formulated to describe patterns observed in living organisms.
Psychologists have been interested in the factors that are important in behavior change and control since psychology emerged as a discipline. One of the first principles associated with learning and behavior was the Law of Effect, which states that behaviors that lead to satisfying outcomes are likely to be repeated, whereas behaviors that lead ...
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 ...
Biological determinism, also known as genetic determinism, [1] is the belief that human behaviour is directly controlled by an individual's genes or some component of their physiology, generally at the expense of the role of the environment, whether in embryonic development or in learning. [2]
Community tolerance can be used as an indicator for determining if a toxicant has a disturbance on an exposed community for multiple types of organisms. [3] Tolerance of a toxicant can increase in three ways: physiological adaptation, also known as the phenotypic plasticity of an individual; tolerant genotypes selected within a population over time; and the replacement of species with more ...
