Effect of Diet and Water Availability on Rattus norvegicus (Rodentia: Muridae) Distribution
The distribution of the Norway rat Rattus norvegicus extends from the subarctic to the subtropics in Japan; yet it is limited by several factors. I discuss appropriate diet, water balance, and temperature as limiting factors based on surveys in the subarctic zone (Yururi-Moyururi, uninhabited island...
