ABSTRACT A common, long‐held belief is that metabolic rate drives the rates of various
biological, ecological and evolutionary processes. Although this metabolic pacemaker view …

Seabird chicks respond to food shortages by increasing corticosterone (cort) secretion,
which is probably associated with fitness benefits and costs. To examine this, we …

Trade-offs between growth and mortality can occur for a variety of reasons. These include
foraging and predation risk, growth and mature function, growth and somatic development …

The reasons why growth and developmental rates vary widely among species have
remained unclear. Previous examinations of possible environmental influences on growth …

Seabirds comprise about 328 species in four orders, the Spenisciformes (penguins; 17
species in one family), Procellariiformes (albatrosses, shearwaters, petrels, diving petrels …

Microstructure–function relationships remain poorly understood in primary bone tissues. The
relationship between bone growth rate and bone tissue type, although documented in some …

Patterns of bone microstructure have frequently been used to deduce dynamics and
processes of growth in extant and fossil tetrapods. Often, the various types of primary bone …

Flexible or innovative behavior is advantageous, especially when animals are exposed to
frequent and unpredictable environmental perturbations. Improved cognitive abilities can …

The survival probability of birds during the juvenile period, between the end of parental care
and adulthood, is highly variable and has a major effect on population dynamics and …

Formerly regarded as pure ecological subjects, the study of distribution, abundance and
population size variation in animals is presented here in an evolutionary framework. This …
