Scaling of insect metabolic rate is inconsistent with the nutrient supply network model
Summary 1The nutrient supply network model of the metabolic theory of ecology predicts that metabolic rate scales as mass0·75 at all hierarchical levels. 2An alternative, cell size, model suggestsExpand

Many insects exchange respiratory gases cyclically and discontinuously. A typical discontinuous gas exchange cycle (DGC) starts with a closed-spiracle (C) phase, during which little external gasExpand

Mass Scaling of Standard Metabolism in Ticks: A Valid Case of Low Metabolic Rates in Sit-and-Wait Strategists
Ticks can survive for a year or more between blood meals, making them the ultimate "sit-and-wait" strategists. We accordingly hypothesize that their standard metabolic rates (SMRs) are unusually low.Expand

Low metabolic rate in scorpions: implications for population biomass and cannibalism.
Scorpions are abundant in arid areas, where their population biomass may exceed that of vertebrates. Since scorpions are predators of small arthropods and feed infrequently across multi-yearExpand

Discontinuous Gas Exchange in Insects: A Clarification of Hypotheses and Approaches*
Many adult and diapausing pupal insects exchange respiratory gases discontinuously in a three‐phase discontinuous gas exchange cycle (DGC). We summarize the known biophysical characteristics of theExpand

Thermolimit respirometry: an objective assessment of critical thermal maxima in two sympatric desert harvester ants, Pogonomyrmex rugosus and P. californicus
SUMMARY The critical thermal maxima (CTmax) of two sympatric, diurnal, thermophilic harvester ants from the Mojave Desert, USA (Pogonomyrmex rugosus and P. californicus) were measured by rampingExpand

Notes from Underground: Towards Ultimate Hypotheses of Cyclic, Discontinuous Gas-Exchange in Tracheate Arthropods'
SYNOPSIS. The Discontinuous Gas-exchange Cycle or DGC is generally thought to have evolved primarily as a means of reducing respiratory water loss rates in tracheate arthropods. However, severalExpand

Fuel selection in rufous hummingbirds: ecological implications of metabolic biochemistry.
Hummingbirds in flight display the highest rates of aerobic metabolism known among vertebrates. Their flight muscles possess sufficient maximal activities of hexokinase and carnitineExpand
