Traditionally, trade-offs are understood in terms of competition for limited resources among traits within an organism, which could be mediated by signal transduction pathways at the level of cellular metabolism. SpletLife history patterns evolve by natural selection, and they represent an "optimization" of tradeoffs between growth, survival, and reproduction.

SpletA trade-off-invariant life-history rule for optimal offspring size Eric L. Charnov* & Jerry F. Downhowert * Department of Biology, University of Utah, Salt Lake City, SpletThe trade-off between current and future reproduction is universal and forms the basis of life-history theory. Brood size manipulations is one of the most common way to test this trade-off. Although the effect of brood size manipulation on immune response have been tested in many studies, little is known about baseline innate immune function.

SpletLife history refers to the pattern of survival and reproduction events during the life of an organism. Life history traits include maximum body size, longevity, age at maturity, and fecundity. Life history theory espouses that these traits have been shaped by natural selection to optimize trade-offs related to growth, reproduction, and survival ... SpletAbstract. It has been hypothesized that tropical trees partition forest light environments through a life history trade-off between juvenile growth and survival; however, the generality of this trade-off across life stages and functional groups has been questioned.

SpletThe trade-off between offspring size and number influences the survival of offspring as they mature. This is an example of trade-offs that occur across life cycle stages, meaning that the benefits and costs to a particular decision are experienced by the organism at … SpletTherefore, the trade-off strategies individuals develop for particular life-history traits in a given environment may profoundly impact their environmental adaptability. In this study, lizards (Eremias. argus) were exposed to single and combined atrazine (4.0 mg·kg -1 and …

Splet13. jun. 2024 · The central trade-off to life history theory is the number of offspring vs. the timing of reproduction. Organisms that are r-selected have a high growth rate ( r ) and tend to produce a high number of offspring with minimal parental care; their lifespans also … Life history characteristics are traits that affect the life table of an organism, and can be imagined as various investments in growth, reproduction, and survivorship. The goal of life history theory is to understand the variation in such life history strategies. This knowledge can be used to construct models to predict what kinds of traits will be favoured in different environments. Without constraints, the highest fitness would belong to a Darwinian de…

SpletEven under good conditions, the stages of human life history are replete with trade-offs for survival, productivity, and reproduction. Under adverse conditions, trade-offs result in reduced survival, poor growth, constraints on physical activity, and poor reproductive …
