..., trade-offs between fighting and escape performance might be sex specific where sexual dimorphism is present, or pronounced in animals with extreme breeding strategies. Northern quolls ( Dasyurus hallucatus ) are a sexually dimorphic marsupial, with sex-specific life history strategies; males die after...

Ledón-Rettig ABSTRACT It has frequently been hypothesized that among-individual variation in behavior and physiology will correlate with life history traits, yet the nature of these correlations can vary. Such variability may arise from plasticity...

Here, we dissect the benefits and costs of Wolbachia infection on life-history traits of the invasive pharaoh ant, Monomorium pharaonis , which are relatively short lived...

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...

...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...

... as a framework for future studies of animal form and function. 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. Second, studies of life histories or mechanistic pathways...

Such work could further differentiate evolutionary effects from those of flight and other aspects of life history on immune defense and provide insights into the traits that promote pathogen...

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