It shows some cold tolerance and bears consistently heavy crops.
This resulted in increased drought tolerance, but did not appear to have any effect on cold tolerance.
In cold climates, it is likely mostly found near human habitat due to its lack of cold tolerance.
The plants also have more cold tolerance.
This is likely due to the significantly increased cold tolerance of black squirrels which lose less heat than greys.
Because of their extreme cold tolerance they have been used to study thermoregulation.
The results showed a 30-40% to 77.4% improvement of cold tolerance but did not provide any data for growth rate.
This "lipid hypothesis of cold tolerance" is less well supported in animals.
It is implied that they have a high cold tolerance, most likely a polar-bear-type Wesen.
Round kumquats are more commonly cultivated than other species due to their cold tolerance.
