Editing Abiotic stress (section)

==In animals==
For animals, the most stressful of all the abiotic stressors is [[heat]].  This is because many species are unable to regulate their internal [[body temperature]].  Even in the species that are able to regulate their own [[temperature]], it is not always a completely accurate system.  Temperature determines [[metabolic rate]]s, [[heart rate]]s, and other very important factors within the bodies of animals, so an extreme temperature change can easily distress the animal's body.  Animals can respond to [[heat wave|extreme heat]], for example, through natural heat acclimation or by burrowing into the ground to find a cooler space.<ref name="roel"/>

It is also possible to see in animals that a high genetic diversity is beneficial in providing resiliency against harsh abiotic stressors.  This acts as a sort of stock room when a species is plagued by the perils of natural selection.  A variety of galling insects are among the most specialized and diverse herbivores on the planet, and their extensive protections against abiotic stress factors have helped the insect in gaining that position of honor.<ref>{{cite journal | last1 = Goncalves-Alvim | first1 = Silmary J. | last2 = Fernandez | first2 = G.
