Trade-offs represent the costs paid in the currency of fitness when a beneficial change in one trait is linked to a detrimental change in another. If there were no trade-offs, then selection would drive all traits correlated with fitness to limits imposed by history and design. However, we find that many life-history traits are maintained well within those limits. Therefore, trade-offs must exist. Trade-offs have played a central role in the development of life-history theory, from Gadgil…

A life-history trade-off gene with antagonistic pleiotropic effects on reproduction and survival in limiting environments

The data suggest that RLS1 is a bona fide life-history trade-off gene that suppresses immediate reproduction and ensures survival by downregulating photosynthesis in limiting environments, as part of the general acclimation response to nutrient deprivation in photosynthetic organisms.

Trade-off-invariant rules for evolutionary stable life histories

In non-growing (stationary), age-structured populations, three major life-history attributes are likely to evolve to equilibrium values that satisfy a universal numerical rule; the underlying trade-off will have a slope of – 1 at the optimum, independent of most other aspects of the trade-offs.

FITNESS COSTS OF FEMALE REPRODUCTION

The approach demonstrates that there is an apparent fitness cost to mating, but not to egg production, in the fruit fly Drosophila melanogaster, and argues that fitness tradeoffs in females that result from resources females allocate to eggs are much lower than fitness trade-offs mediated in part by male-female interactions.

The Physiology of Life History Trade-Offs in Animals

A review of life historyTrade-offs discusses conceptual issues associated with physiological aspects of trade-offs, and it describes recent advances on this topic.

Positive phenotypic correlations among life‐history traits remain in the absence of differential resource ingestion

It is demonstrated that strong positive correlations among life- history traits emerge from variation among individuals in an underappreciated aspect of their energy budget, and reinforces the potential role that physiological ecology has in shaping life-history trait correlations.

Life history trade-offs imposed by dragline use in two money spiders

Strong trade-offs between dragline spinning and survival and fecundity are demonstrated and rare but energetically costly decisions related to dispersal or predator escape may carry over to adult performance and explain phenotypic heterogeneity in natural populations.

Detecting life history trade-offs: measuring energy stores in “capital” breeders reveals costs of reproduction

Analysis of energy stores and reproductive output in Eulamprus tympanum, a viviparous scincid lizard that stores energy for reproduction in its tail, finds that non-destructive measurement of pre- and post-reproductive energy stores may greatly enhance the ability to detect significant life history trade-offs.

Parasites and the Costs of Reproduction in Soay Sheep

This thesis attempts to explore the interaction between parasites and the costs of reproduction in a wild population of Soay sheep on the Scottish island group of St Kilda, suggesting that the spring rise in parasitism is partly associated with poor body condition.

Trade-Offs (and Constraints) in Organismal Biology

A pluralistic view of trade-offs and constraints, combined with integrative analyses that cross levels of biological organization and traditional boundaries among disciplines, will enhance the study of evolutionary organismal biology.

Costs of reproduction: an evaluation of the empirical evidence

It is argued that a relevant empirical study must deal with genetically based tradeoffs, and only the last two methods properly address the "costs" dealt with by theoreticians.

Alternative Concepts of Reproductive Effort, Costs of Reproduction, and Selection in Life-History Evolution

An outline for an organismic theory of reproductive tactics is presented to develop the demographic theory of optimal reproductive tactics into a more realistic theory of life-history evolution and compensation and threshold hypotheses are put forward to allow weaker correlations between reproduction and survival.

A critique of methods for measuring life history trade‐offs

This work investigates methods for measuring a specific type of constraint known as a trade‐off, which implies a perfect negative correlation between two traits and may involve more than two traits.

The Ecological Context of Life History Evolution

There is now a good theoretical understanding of life history evolution, and detailed explicit optimality models have been constructed. These present a challenge for empirical work examining some of

A general test of the supposed adaptiveness of deferred male reproduction is suggested: when male competitive ability depends on size, the reproductive activity ofyounger males should vary inversely with the intensity of sexual selection.

MEASURING THE COST OF REPRODUCTION: A COMMENT ON PAPERS BY BELL

It is argued here that the results of Bell's experiments may not be correct because only a subset of the analyses really address the role that costs play in models of life-history evolution; the dependent variables in other analyses in the first paper do not measure what Bell claims, and his misinterpretation of these variables nullifies these analyses.
