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 ...
Life history is an interviewing method used to record autobiographical history from an ordinary person's perspective, often gathered from traditionally marginalized groups. It was begun by anthropologists studying Native American groups around the 1900s, and was taken up by sociologists and other scholars, though its popularity has waxed and ...
Life history may refer to: Life history theory, a theory of biological evolution that seeks to explain aspects of organisms' anatomy and behavior by reference to the way that their life histories have been shaped by natural selection; Life history (sociology), the overall picture of an informant's or interviewee's life
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).
The term life history is often used, particularly for organisms such as the red algae which have three multicellular stages (or more), rather than two. [ 3 ] Life cycles that include sexual reproduction involve alternating haploid ( n ) and diploid (2 n ) stages, i.e., a change of ploidy is involved.
Related to this is the idea of a life history strategy, which can be conceptualized as a chain of resource-allocation decisions (e.g., allocating resources towards growth or towards reproduction) that an organism makes. [1]

It is a biological precept that within its lifetime an organism has a limited amount of energy/resources available to it, and must always partition it among various functions such as collecting food and finding a mate. Of relevance here is the trade-off between fecundity, growth, and survivorship in its life history strategy. These trade-offs ...
