Detailed explanation-1: -Hibernation. Some boreal forest animals avoid the stresses of winter by spending the cold season in hibernation. Brown bears and black bears, marmots, and jumping mice hibernate. Wood frogs and many species of insects hibernate so deeply that their bodies actually freeze.
Detailed explanation-2: -Animal adaptations Most animals migrate to warmer climates once the cold weather begins. Some animals have adapted to life in the taiga by hibernating when temperatures drop. Other animals have adapted to the extreme cold temperatures by producing a layer of insulating feathers or fur to protect them from the cold.
Detailed explanation-3: -During the summer in the boreal forest, warm, moist air from the Pacific air mass moves north, bringing warm weather and rain. During the winter, cold, dry air from the Arctic air mass pushes south, into the boreal forest, causing the cold, dry winters.
Detailed explanation-4: -In the boreal forests, the symbiosis between epiphytic cyanobacteria and feathermosses Hylocomium splendens and Pleurozium schreberi is ecologically important. The main input of biological N to the boreal forests is through these cyanobacteria, and thus, they greatly contribute to the productivity of this ecosystem.
