Rana amurensis (Khabarovsk frog, Siberian wood frog, Heilongjiang brown frog or Amur brown frog) is a species of true frog found in northern Asia. Rana coreana was previously included in this species as a subspecies.[1][2]
Distribution and habitat[edit]
It ranges across western Siberia, as well as northeastern China, northeastern Mongolia, and on the northern Korean Peninsula and on Sakhalin.[3] Found at latitudes up to 71° N, it is the northernmost wild amphibian species.[4] Favoring lowlands, it is seldom encountered at elevations of more than 600 m.[1] A habitat generalist, Rana amurensis favors open ground, but is also found in both deciduous and coniferous forests. In the winter, it hibernates on pond bottoms.
Conservation[edit]
According to the IUCN, the chief threat to the species is habitat loss, as it is only mildly tolerant of disturbance. In addition, it has become a frequent subject of hunting in Russia since the 1990s. It is not considered threatened on a global scale though.[1]
Description[edit]
Adults are light brown with smooth skin and irregular dark brown and yellow stripes, with a body length of 2–2.5 cm (0.79–0.98 in).[5]
Diet and breeding[edit]
Rana amurensis favors beetles, and consumes 1.2–2.5 g (0.0026–0.0055 lb) of food per day. The average lifespan is three years. Their breeding season is very early, starting in late February in Korea. An egg sac contains 30-60 eggs.[5]
