Shelford's law of tolerance is a principle developed by American zoologist Victor Ernest Shelford in 1911. It states that an organism 's success is based on a complex set of conditions and that each organism has a certain minimum, maximum, and optimum environmental factor or combination of factors that determine success.

specialist species – those that can only thrive in a narrow range of environmental conditions and/or have a limited diet. specific heat capacity – the amount of energy needed to increase the temperature of 1 kg of a substance by 1oC. It can be considered a measure of resistance to an increase in temperature and important for energy saving.
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.
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 ...
"Ape", from Old English apa, is a word of uncertain origin. [b] The term has a history of rather imprecise usage—and of comedic or punning usage in the vernacular.Its earliest meaning was generally of any non-human anthropoid primate, as is still the case for its cognates in other Germanic languages.
Core populations are those occurring within the centre of the range, and marginal populations (also called peripheral populations) are found at the boundary of the range. The inability of a species to expand its range beyond a certain geographic area is because of some limiting factor or factors to which the species cannot successfully adapt.
In botany, drought tolerance is the ability by which a plant maintains its biomass production during arid or drought conditions. [ 1 ] [ 2 ] [ 3 ] Some plants are naturally adapted to dry conditions , surviving with protection mechanisms such as desiccation tolerance , detoxification , or repair of xylem embolism. [ 3 ]
