heat tolerance
- Avian thermoregulation in the heat: is evaporative cooling more economical in nocturnal birds?
Summary: Caprimulgids and Australian owlet-nightjars displayed allometrically lower water losses compared with diurnal birds, whereas owls exhibited water losses comparable to those of similarly sized diurnal birds.
- Reversibility of developmental heat and cold plasticity is asymmetric and has long-lasting consequences for adult thermal tolerance
Summary: Using Drosophila melanogaster, we show how developmental plasticity of cold tolerance is completely reversible in the adult stage, while adult acclimation in heat tolerance is constrained by developmental temperature.
- The temperature dependence of electrical excitability in fish hearts
Summary: At the extremes of environmental temperature, electrical excitability of the heart and other excitable tissues may set limits to temperature tolerance of fishes and other ectotherms.
- Plasticity of upper thermal limits to acute and chronic temperature variation in Manduca sexta larvae
Summary: Heat tolerance in Manduca sexta larvae is affected by both the magnitude and the temporal pattern of previous exposure to high temperatures.
- Oxygen-limited thermal tolerance is seen in a plastron-breathing insect and can be induced in a bimodal gas exchanger
Summary: Oxygen does not appear to universally limit thermal tolerance, but instead, oxygen-limited thermal tolerance is context dependent, being related to a species’ capacity to regulate oxygen consumption.
