A life history strategy is the "age- and stage-specific patterns" [2] and timing of events that make up an organism's life, such as birth, weaning, maturation, death, etc. [3] These events, notably juvenile development, age of sexual maturity, first reproduction, number of offspring and level of parental investment, senescence and death, depend ...
The terminology of r/K-selection was coined by the ecologists Robert MacArthur and E. O. Wilson in 1967 [2] based on their work on island biogeography; [3] although the concept of the evolution of life history strategies has a longer history [4] (see e.g. plant strategies).
Kirk O. Winemiller is an American ecologist, known for research on community ecology, life history theory, food webs, aquatic ecosystems, tropical ecology and fish biology. A strong interest of his has been convergent evolution and patterns, causes and consequences of biological diversity, particularly with respect to fishes.
John Philip Grime FRS [1] (30 April 1935 – 19 April 2021) [2] was an ecologist and emeritus professor at the University of Sheffield. [3] He is best known for the universal adaptive strategy theory (UAST) and the twin filter model of community assembly with Simon Pierce, eco-evolutionary dynamics, the unimodal relationship between species richness and site productivity ("humped-back model ...
At this time, strategies were often associated with genotypic changes, such that plants could respond to their environment by changing their “genotypic programme” (i.e., strategy). [1] [2] Around this same time, the r/K selection theory was introduced, which classifies plants by life history strategies, particularly reproductive strategies.
Annual plant – Plant which completes its life cycle within one growing season and then dies; Behavioral ecology – Study of the evolutionary basis for animal behavior due to ecological pressures; Ecology – Study of organisms and their environment; Life history theory – Analytical framework to study life history strategies used by organisms
A population ecology concept is r/K selection theory, one of the first predictive models in ecology used to explain life-history evolution. The premise behind the r/K selection model is that natural selection pressures change according to population density. For example, when an island is first colonized, density of individuals is low.
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 ...
