Scaling of insect metabolic rate is inconsistent with the nutrient supply network model
- S. Chown, E. Marais, J. Terblanche, C. Klok, J. Lighton, T. Blackburn
- Biology

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 suggests… Expand
Discontinuous gas exchange in insects.
- J. Lighton
- Biology, Medicine
- Annual review of entomology
- 1996
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 gas… Expand
Mass Scaling of Standard Metabolism in Ticks: A Valid Case of Low Metabolic Rates in Sit-and-Wait Strategists
- J. Lighton, L. Fielden
- Biology
- Physiological Zoology
- 1 January 1995
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.
- J. Lighton, P. Brownell, B. Joos, R. Turner
- Biology, Medicine
- The Journal of experimental biology
- 1 February 2001
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-year… Expand
Discontinuous Gas Exchange in Insects: A Clarification of Hypotheses and Approaches*
- S. Chown, A. Gibbs, S. K. Hetz, C. Klok, J. Lighton, E. Marais
- Biology, Medicine
- Physiological and Biochemical Zoology
- 2 February 2006
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 the… Expand
Thermolimit respirometry: an objective assessment of critical thermal maxima in two sympatric desert harvester ants, Pogonomyrmex rugosus and P. californicus
- J. Lighton, R. Turner
- Biology, Medicine
- Journal of Experimental Biology
- 1 May 2004
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 ramping… Expand
Discontinuous Ventilation in Terrestrial Insects
- J. Lighton
- Biology
- Physiological Zoology
- 1 January 1994
Current knowledge concerning the occurrence, distribution, and mechanism of the insect discontinuous ventilation cycle, or DVC, is evaluated in the light of recent data. The congruence between the… Expand
Notes from Underground: Towards Ultimate Hypotheses of Cyclic, Discontinuous Gas-Exchange in Tracheate Arthropods'
- J. Lighton
- Biology
- 1 June 1998
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, several… Expand
Fuel selection in rufous hummingbirds: ecological implications of metabolic biochemistry.

- Proceedings of the National Academy of Sciences…
- 1 December 1990
Hummingbirds in flight display the highest rates of aerobic metabolism known among vertebrates. Their flight muscles possess sufficient maximal activities of hexokinase and carnitine… Expand
