== Thermoregulation ==
As an [[ectotherm]], the common frog is highly dependent on temperature as it directly affects its [[metabolism]], development, reproduction, muscular strength, and respiration. As such, common frogs at medium and high elevations have developed a unique set of strategies to survive in cold climates. In fact, it is due to the common frog's ability to thermoregulate so effectively that the species has been able to become so widespread in a variety of environments and climates, living as far north as the [[Arctic Circle]] in [[Scandinavia]], which is further north than any other amphibian in the region.<ref name="Ludwig-2015" /> Contrary to ''[[Wood frog|''Lithobates sylvaticus'']]'' (wood frogs), common frogs do not have the ability to freeze protect themselves by increasing their levels of blood glucose to serve as a [[cryoprotectant]].<ref name="Ludwig-2015">{{cite journal |last1=Ludwig |first1=Gerda |last2=Sinsch |first2=Ulrich |last3=Pelster |first3=Bernd |date=1 April 2015 |title=Behavioural adaptations of Rana temporaria to cold climates |journal=Journal of Thermal Biology |volume=49-50 |pages=82–90 |doi=10.1016/j.jtherbio.2015.02.006 |pmid=25774030 |bibcode=2015JTBio..49...82L |ref=thermoreg}}</ref> As a result, common frogs must rely on behavioral thermoregulation by seeking out warm microhabitats (such as in the soil or between rocks) during wintertime. In addition, common frogs often hibernate in groups during the winter season in order to maintain body heat.<ref name="Ludwig-2015" />
