... in poorer reproductive success because the holder cannot retain a good territory ( Reaney et al., 2008 ). Different developmental trajectories can thus result in apparently the same adult external morphology, but lead to very different life histories. The mechanisms underlying these trends can be hard...

...Alexander Hansson; Erik Wapstra; Geoffrey M. While; Mats Olsson ABSTRACT Telomeres, the repetitive DNA regions that protect the ends of chromosomes, and their shortening have been linked to key life history trade-offs among growth, reproduction and lifespan. In contrast to most endotherms, many...

First, studies of performance should consider the broader life-history context of the organism, and vice versa, as performance expression can require a large portion of acquired resources.

The results, nevertheless, demonstrate that physiological changes coincide with the divergence of life histories between the alternative...
