11. However, flying insects raise their body temperature through the action of flight, above environmental temperatures . 12. In many species, the animal switches from nocturnal to diurnal foraging depending on the environmental temperature . 13. Very rare in turtles where the gender of developing embryos are usually determined by environmental temperatures . 14. "Octopus vulgaris " can apply behavioral changes in order to manage wide varieties of environmental temperatures . 15. It is actuated by controlling the environmental temperature and by positioning a scanning tunneling microscope tip. 16. Experiments with rats and bats had hinted that environmental temperatures could affect the sex ratio of offspring. 17. Most standard commercial crystals are specified to an environmental temperature of, industrial versions are usually specified to. 18. When there is a large range of environmental temperatures , newts are very insensitive to a thermal gradient profile. 19. Some causes of diaphoresis include physical exertion, menopause, fever, ingestion of toxins or irritants, and high environmental temperature . 20. Environmental temperature affects the magnetic forces of magnets and the winding resistance, and so indicates changes in motor performance.
