Thermal performance
- The effect of ambient oxygen on the thermal performance of a cockroach, Nauphoeta cinerea
Summary: Oxygen availability does not explain moderate- to long-term thermal performance in Nauphoeta cinerea, which raises further questions about the generality of the OCLTT hypothesis.
- Reproductive fitness of Drosophila is maximised by optimal developmental temperature
Summary: Developmental acclimation does not necessarily enhance reproductive fitness in Drosophila melanogaster; instead, the highest fitness is achieved by development at an optimal temperature.
- Phenotypic plasticity in locomotor performance of a monophyletic group of weevils accords with the ‘warmer is better’ hypothesis
Summary: Among nine weevil populations representing five species from the sub-Antarctic, acclimation responses of locomotion thermal performance curves typically accord with the warmer is better (or thermodynamic effects) hypothesis.
- Thermosensory perception regulates speed of movement in response to temperature changes in Drosophila melanogaster
Highlighted Article: Although flies modulate speed in response to temperature following the same dynamic as metabolic reactions, this response is controlled by the nervous system and not by a direct thermal influence on metabolism.
- Thermal acclimation and subspecies-specific effects on heart and brain mitochondrial performance in a eurythermal teleost (Fundulus heteroclitus)
Summary: Heart and brain mitochondrial performance declines following acclimation to thermal extremes in killifish, which suggests that organismal performance at thermal extremes is, at least in part, constrained by mitochondrial performance.
- Phenophysiological variation of a bee that regulates hive humidity, but not hive temperature
Summary: Conservation of water may be of greater physiological importance than thermal tolerance to the tropical bee Austroplebeia essingtoni, which regulates humidity of the hive towards a microclimatic optimum.
