Phylogenetic Studies of Coadaptation: Preferred Temperatures versus Optimal Performance Temperatures of Lizards.
The view that behavior and physiological performance are tightly coadapted is a central principle of physiological ecology. Here, we test this principle using a comparative study of evolutionary patterns in thermal preferences and the thermal dependence of sprinting in some Australian skinks (Lygosominae). Thermal preferences (Tp ) differ strikingly among genera (range 24° to 35°C), but critica...
متن کاملThermoeffector thresholds and preferred ambient temperatures of the FOK rat.
The FOK is an inbred rat strain with a genotypic adaptation to hot environments. The present study compared the thermoeffector thresholds and preferred ambient temperatures (Tpref) of the FOK rat with those of other rat strains. Male FOK, WKAH, and Donryu rats were used. First, they were loosely restrained and placed individually in a metabolic chamber with an ambient temperature of 26.0°C. The...
متن کاملAlcohol Fuel Cells at Optimal Temperatures
High-power-density alcohol fuel cells can relieve many of the daunting challenges facing a hydrogen energy economy. Here, such fuel cells are achieved using CsH2PO4 as the electrolyte and integrating into the anode chamber a Cu-ZnO/Al2O3 methanol steam-reforming catalyst. The temperature of operation, 250°C, is matched both to the optimal value for fuel cell power output and for reforming. Peak...
متن کاملEvolution of Sprint Speed in Lacertid Lizards: Morphological, Physiological, and Behavioral Covariation.
Organismal performance abilities occupy a central position in phenotypic evolution; they are determined by suites of interacting lower-level traits (e.g., morphology and physiology) and they are a primary focus of natural selection. The mechanisms by which higher levels of organismal performance are achieved during evolution are therefore fundamentally important for understanding correlated evo...
متن کاملPhylogeny and Coadaptation of Thermal Physiology in Lizards: a Reanalysis.
Traditional comparative studies examine evolutionary associations of traits by comparing different species, regardless of their phylogenetic relationships. A problem with such an approach is that trait values for each species are not statistically independent. This is so because species partially share evolutionary histories (Felsenstein, 1985). Another problem is that "equilibrium" patterns se...
