摘要:Evidence across a broad range of disciplines has demonstrated how individuals' social environments can impact their health, lifespan, reproduction, and ultimately their evolutionary fitness. Past research has primarily focused on either traits specific to individuals or wider traits of social groups, linking these with a component of fitness. In this study, we examined how both individual-and group-level social traits in 164 wild mountain gorillas combine to influence multiple pathways impacti...

摘要:Intensely contracting fast skeletal muscle rapidly loses the ability to generate force, due in part to the accumulation of phosphate (Pi) inhibiting myosin's force-generating capacity, in a process that is strain dependent. Crucial aspects of the mechanism underlying this inhibition remain unclear. Therefore, we directly determined the effects of increasing [Pi] on rabbit psoas muscle myosin's ability to generate force against progressively higher resistive loads in a laser trap assay, with th...
