- Thermoregulation in desert birds: scaling and phylogenetic variation in heat tolerance and evaporative cooling
Summary: Many physiological variables related to avian heat tolerance vary significantly with body mass, but also vary substantially among taxa that differ in their reliance on panting, gular flutter or cutaneous evaporation for evaporative heat dissipation.
- Avian thermoregulation in the heat: phylogenetic variation among avian orders in evaporative cooling capacity and heat tolerance
Summary: Avian evaporative cooling efficiency and heat tolerance display substantial taxonomic variation that are, unexpectedly, not systematically related to the use of panting versus gular flutter processes.
