Insects can experience functional hypoxia, a situation in which O2 supply is inadequate to
meet oxygen demand. Assessing when functional hypoxia occurs is complex, because …

Sexual selection drives the evolution of some of the most exaggerated traits in nature.
Studies on sexual selection often focus on the size of these traits relative to body size, but …

Metabolism energizes all biological processes, and its tempo may importantly influence the
ecological success and evolutionary fitness of organisms. Therefore, understanding the …

Temperature is a key factor that affects the rates of growth and development in animals,
which ultimately determine body size. Although not universal, a widely documented and …

Both the slope and elevation of scaling relationships between log metabolic rate and log
body size vary taxonomically and in relation to physiological or developmental state …

Insect tracheal-respiratory systems achieve high fluxes and great dynamic range with low
energy requirements and could be important models for bioengineers interested in …

ABSTRACT A mismatch between oxygen availability and metabolic demand may constrain
thermal tolerance. While considerable support for this idea has been found in marine …

Biological invasions are one of the biggest threats to global biodiversity. Marine artificial
structures are proliferating worldwide and provide a haven for marine invasive species …

Traditionally, physiologists have estimated the ability of organisms to withstand lower partial
pressures of oxygen by estimating the partial pressure at which oxygen consumption begins …

Population density and associated behavioral adjustments are potentially important in
regulating physiological performance in many animals. In r-selected species like the fruit fly …
