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.
The metabolic theory of ecology (MTE) [1] is the ecological component of the more general Metabolic Scaling Theory [2] and Kleiber's law. It posits that the metabolic rate of organisms is the fundamental biological rate that governs most observed patterns in ecology. MTE is part of a larger set of theory known as metabolic scaling theory that ...
Universal adaptive strategy theory (UAST) is an evolutionary theory developed by J. Philip Grime in collaboration with Simon Pierce describing the general limits to ecology and evolution based on the trade-off that organisms face when the resources they gain from the environment are allocated between either growth, maintenance or regeneration ...
Metabolic rift is a theory of ecological crisis tendencies under the capitalist mode of production that sociologist John Bellamy Foster ascribes to Karl Marx.Quoting Marx, Foster defines this as the "irreparable rift in the interdependent process of social metabolism".
Additionally, this method has supported correlations between prions (pathogenic misfolded proteins) and conditions like Creutzfeldt–Jakob disease because Koch's postulates are focused on foreign microorganisms, rather than the results of host mutations.
Evolutionary game theory – Application of game theory to evolving populations in biology; Evolutionary graph theory – Approach to studying how topology affects evolution of a population; Evolutionary invasion analysis – Mathematical modeling of phenotypic evolution; Largest-scale trends in evolution – Limits of increased complexity over ...
The redundancy is often generated for the purpose of resolving the time constraint of fast-activating pathways. It can be expressed in terms of the theory of extreme statistics to determine its laws and quantify how the shortest paths are selected. The main goal is to estimate these large numbers from physical principles and mathematical ...
Paramecium aurelia and Paramecium caudatum grow well individually, but when they compete for the same resources, P. aurelia outcompetes P. caudatum.. Based on field observations, Joseph Grinnell formulated the principle of competitive exclusion in 1904: "Two species of approximately the same food habits are not likely to remain long evenly balanced in numbers in the same region.
