Comparative studies of mortality in the wild are necessary to understand the evolution of
aging; yet, ectothermic tetrapods are underrepresented in this comparative landscape …

Is senescence inevitable and universal for all living organisms, as evolutionary theories
predict? Although evidence generally supports this hypothesis, it has been proposed that …

Animal lifespan is determined by extrinsic and intrinsic factors causing mortality. According
to the evolutionary theories of senescence, when mortality pressures are low, animals delay …

Aim The 'rate‐of‐living'theory predicts that life expectancy is a negative function of the rates
at which organisms metabolize. According to this theory, factors that accelerate metabolic …

Variation in temperature is known to influence mortality patterns in ectotherms. Even though
a few experimental studies on model organisms have reported a positive relationship …

Climate change–induced mass extinctions provide unique opportunities to explore the
impacts of global environmental disturbances on organismal evolution. However, their …

The field of comparative ageing biology has greatly expanded in the past 20 years.
Longitudinal studies of populations of reptiles with a range of maximum lifespans have …

Understanding which species and ecosystems will be most severely affected by warming as
climate change advances is important for guiding conservation and management. Both …

Body temperature is a crucial variable in animals that affects nearly every aspect of their
lives. Here we analyze for the first time largescale patterns in the evolution of body …

Human activity is changing climatic conditions at an unprecedented rate. The impact of
these changes may be especially acute on ectotherms since they have limited capacities to …
