Life‐history theory postulates that physiological traits, such as energy metabolism, can be
understood in terms of allocation trade‐offs between self‐maintenance and reproduction …

Life history varies across latitudes, with the 'pace of life'being 'slower'in tropical regions.
Because life history is coupled to energy metabolism via allocation tradeoffs and links …

Survival rates vary dramatically among species and predictably across latitudes, but causes
of this variation are unclear. The rate‐of‐living hypothesis posits that physiological damage …

For vertebrates, body mass underlies much of the variation in metabolism, but among
animals of the same body mass, metabolism varies six-fold. Understanding how natural …

Animal life-history traits fall within limited ecological space with animals that have high
reproductive rates having short lives, a continuum referred to as a “slow-fast” life-history axis …

Tropical birds are relatively long-lived and produce few offspring, which develop slowly and
mature relatively late in life, the slow end of the life-history axis, whereas temperate birds lie …

Tropical birds live longer, have smaller clutches and invest more resources into self‐
maintenance than temperate species. These “slow” life‐histories in tropical birds are …

Compared with temperate birds, tropical birds have low reproductive rates, slow
development as nestlings, and long lifespans. These “slow” life history traits are thought to …

Attributes of an animal's life history, such as reproductive rate or longevity, typically fall along
a 'slow–fast'continuum. Animals at the fast end of this continuum, such as temperate birds …

Metabolism is a defining feature of all living organisms, with the metabolic process resulting
in the production of free radicals that can cause permanent damage to DNA and other …
