Behavioral thermoregulation by fishes: a new experimental approach.
نویسندگان
چکیده
Electronic equipment allows fishes, by their spatial movements, to regulate the temperature in experimental tanks. Swimming into warmer water causes the temperature of the entire tank to increase; conversely, swimming into cooler water causes the temperature to decrease. The technique may be adapted for studying simultaneous behavioral regulation of temperature and nonthermal factors.

Heterothermy in two mole-rat species subjected to interacting thermoregulatory challenges.
Maintaining a high and constant body temperature (T(b) ) is often viewed as a fundamental benefit of endothermy, but variation in T(b) is likely the norm rather than an exception among endotherms. Thus, attempts to elucidate which factors cause T(b) of endotherms to deviate away from the T(b) that maximizes performance are becoming more common. One approach relies on an adaptive framework of th...
متن کاملBehavioral thermoregulation by turtle embryos.
Mobile ectothermic animals can control their body temperatures by selecting specific thermal conditions in the environment, but embryos--trapped within an immobile egg and lacking locomotor structures--have been assumed to lack that ability. Falsifying that assumption, our experimental studies show that even early stage turtle embryos move within the egg to exploit small-scale spatial thermal h...
متن کاملThe relative overlooking of human behavioral temperature regulation: An issue worth resolving
It has long been appreciated that behavior is the most powerful and diverse thermoregulatory mechanism. In animal-based studies a behavioral assay is typically the first assessment when investigating the effect of a perturbation on thermoregulation, highlighting its importance. Oddly however, such an approach has been largely ignored in human research.
متن کاملEvaluating the roles of energetic functional constraints on teleost mitochondrial-encoded protein evolution.
Mitochondria are the power plant of cells, which play critical roles not only in energy metabolism but also in thermoregulation. These two roles have been individually suggested to influence mitochondrial DNA (mtDNA) evolution, however their relative importance is still rarely considered. Here, we conduct a comparative genomic analysis of 401 teleost complete mitochondrial genomes and test the ...
متن کامل"Behavioral Thermoregulation by Turtle Embryos" (2011), by Wei-Guo Du, Bo Zhao, Ye Chen, and Richard Shine
In ?Behavioral Thermoregulation by Turtle Embryos,? published in Proceedings of the National Academy of Sciences [4] in April, 2011, Wei-Guo Du, Bo Zhao, Ye Chen, and Richard Shine report that turtle embryos can move towards warmer temperatures within the egg [5] when presented with a small, 0.8 degrees Celsius gradient. This behavioral thermoregulation may benefit the embryo?s fitness by accel...
