Life history tradeoffs
Web10. dec 2024. · Much life-history theory traditionally focused on trade-offs that affect resource allocation to survival, growth, and reproduction—e.g., between number and size of offspring in a clutch or litter or of offspring produced over a lifetime; between semelparous and iteroparous reproduction (i.e., “ big bang” or “1 shot” vs. multiple reproductive bouts); … Web18. dec 2007. · We argue that human pygmy populations and adaptations evolved independently as the result of a life history tradeoff between the fertility benefits of larger body size against the costs of late growth cessation, under circumstances of significant young and adult mortality.

This paper proposes two new concepts, i.e., “lifespan of pathogens” and treatment of infections by “antibiogenesis”. The lifespan of pathogens is the time limitation of those tiny lives just as other large creatures.
WebAs noted in the introduction, unobserved variation in energetic condition or access to resources commonly masks life-history tradeoffs (van Noordwijk & de Jong, Reference van Noordwijk and de Jong 1986), including in humans (Sear, Reference Sear 2024; Sear et al., Reference Sear, Mace and McGregor 2003). Web01. avg 2024. · The fundamental trade-offs cited in human applications are: (1) current vs. future reproduction, (2) quantity vs. quality of offspring, and (3) matting effort vs. …
WebTrade-offs between traits are a fundamental component of life history theory. However, because individuals may differ in the amount of energy available for allocation between traits, expected negative relationships are often difficult to detect or may become positive.
