Published: 21 November 2022
...Alberto A. Castro; Theodore Garland; Saad Ahmed; Natalie C. Holt A trade-off between locomotor speed and endurance occurs in various taxa, and is thought to be underpinned by a muscle-level trade off. Among four replicate High Runner (HR) lines of mice, selectively bred for voluntary wheel-running...

... of functional trade-offs (i.e. improvement in one trait comes at the expense of another trait) or alternatively may reflect the intrinsic quality of an organism (i.e. some individuals are simply better overall performers than others). There is evidence for both ideas in the literature, suggesting...

...Jerry F. Husak; Simon P. Lailvaux ABSTRACT Phenotypic trade-offs are inevitable in nature, but the mechanisms driving them are poorly understood. Movement and oxygen are essential to all animals, and as such, the common ancestor to all living animals passed on mechanisms to acquire oxygen...

... contributed to low nesting rates of bees exposed to constant low temperatures. Females from that group that were able to nest had fewer, larger offspring with high viability, suggesting a trade-off. Interestingly, offspring of bees exposed to fluctuating low temperatures were more likely to enter diapause...

.... Therefore, TH production may become costly when environmental iodine availability is low. This may yield a trade-off for breeding females between allocating the hormones to self or to their eggs, potentially to the extent that it even influences the number of laid eggs. In this study, we investigated...

Nonetheless, basal heat tolerance often correlates negatively with tolerance plasticity (‘trade-off hypothesis’), a constraint that could...

Although survival-related traits often trade off with reproduction, survival-related traits themselves may trade off with each other under energy limitations. Whole-organism performance...
