...Fredrik Andreasson; Arne Hegemann; Andreas Nord; Jan-Åke Nilsson ABSTRACT The capacity to get rid of excess heat produced during hard work is a possible constraint on parental effort during reproduction [heat dissipation limit (HDL) theory]. We released hard-working blue tits ( Cyanistes caeruleus...

...Julita Sadowska; Andrzej K. Gȩbczyński; Małgorzata Lewoc; Marek Konarzewski ABSTRACT Heat dissipation has been suggested as a limit to sustained metabolic effort, e.g. during lactation, when overheating is a possible risk. We tested this hypothesis using mice artificially selected for either high...

... to increase evaporative heat dissipation when body temperature ( T b ) approached 41.5°C in response to increasing T a , with gular flutter observed in cuckoos and panting in rollers and starlings. Resting metabolic rate and evaporative water loss increased by quantitatively similar magnitudes in all three...

...Mirre J. P. Simons; Inonge Reimert; Vincent van der Vinne; Catherine Hambly; Lobke M. Vaanholt; John R. Speakman; Menno P. Gerkema SUMMARY The heat dissipation limit theory suggests that heat generated during metabolism limits energy intake and, thus, reproductive output. Experiments in laboratory...

... facilitates evaporation of water trapped within the seals' pelages due to increased saturation vapour pressure. The comparatively large latent heat necessary for evaporation creates a temporary hot spot for heat dissipation. References Boily, P. and Lavigne, D. M. ( 1996 ). Thermoregulation of juvenile...
