Question

You design a study to test Bergmann's rule in relation to climate change. Which of the following would be an appropriate hypothesis for the study? Hints O As global temperatures decrease, smaller animals will be found at higher altitudes. O As global temperatures decrease, smaller animals will be found at higher latitudes. O As global temperatures increase, smaller animals will be found at higher latitudes. O . As global temperatures increase, larger animals wil be found at lower latitudes OAs global temperatures decrease, larger animals will be found at lower latitudes.

Explanation / Answer

Answer: As global temperature decrease, large animals will be found at lower latitudes
      
Explanation: The above conclusion will be correct because Bergmann's rule is maily correlated the body size and temperature. As increase in body size with decreasing environmental temperature known as Bergmann's clines. Bergmann's Rule establishes a general tendency of endotherms to achieve larger body sizes in higher latitudes, and thus, in colder environments. As at the higher latitude the temperature is less so the body size of he animals has large. Heat is dissipated more slowly in larger animals as the surface-area to volume ratio diminishes, so it would be a thermal advantage in colder habitats. Bergmann's Rule has been widely supported in endotherms
