... wing colouration such as melanin. Competing for the same resources often leads to trade-offs in resource allocation. We manipulated protein availability in the larval diet of the wood tiger moth, Arctia plantaginis , to test how early life resource availability influences relevant life history traits...

...Alberto A. Castro; Theodore Garland, Jr; Saad Ahmed; Natalie C. Holt ABSTRACT 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...

... 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...

... in driving the growth–lifespan trade-off (reviewed in Monaghan and Ozanne, 2018 ). Our results, however, suggest that the effects of growth on telomere length are indirectly mediated by the decline in telomerase activity, and the direct effect of growth on telomere length (if any) was minor. In this regard...

...Sean W. Deery; Julie E. Rej; Daniel Haro; Alex. R. Gunderson ABSTRACT Heat tolerance plasticity is predicted to be an important buffer against global warming. Nonetheless, basal heat tolerance often correlates negatively with tolerance plasticity (‘trade-off hypothesis’), a constraint that could...

... ). Regulatory mechanisms of maternal hormone transfer are essential to minimise physiological trade-offs between optimal hormone exposure in the mother versus that in the offspring ( Groothuis and Schwabl, 2008 ). For example, circulating THs increase with low temperature to stimulate metabolism and hence heat...

...Andrew Z. Wang; Jerry F. Husak ABSTRACT Limited resources must be partitioned among traits that enhance fitness. 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...

Life history theory predicts that considerably increased growth and developmental rates should be traded off against other costly life history traits. However, it is not clear whether one should...

We predict that semi-aquatic and aquatic salamandrids with hyobranchial morphology suited for aquatic feeding will have lower...

Therefore, we suggest that, under metabolic stresses incurring trade-offs involving an immune response, mice selected...
