The environments in the forest alter drastically over the period of the year and living creatures have to adjust to changes in seasons in order to survive. Climate changes, precipitation, and food supply can alter the behavior of animals, and compel them to adapt a specific evolutionary strategy.
The spring is a period of rejuvenation of forests as vegetation grows and there is an increase in the numbers of insects. This season is characterized by plenty food that is exploited by many animals. Birds nest and have their chicks, and the animals find new fodder and insects in the spring after winter shortage.
Autumn is a transitional season when the animals are preparing towards winter. Most species augment their feeding patterns to accumulate fats. Their foraging makes more sense as the foraging behavior of squirrels, the migration behavior of the birds and the hunting patterns of the predator adapt to the varying availability of prey.
Most of the forest animals face the biggest survival problem during winter. Low temperatures decrease food supply and snow can fall on vegetation or prey which is under the ground. Strategies used by animals involve hibernating, migrating or having heavier fur coats.
Foxes are very adaptable in winter. They are safe against the cold weather since they have thick fur and good sense of hearing assists them in finding food under the snow. Foxes are able to hunt animals even under extreme circumstances with neat movements and huge leaps.
Natural seasonal cycle has started to be affected by climate change. Climate change, through warmer winters, unpredictable rainfalls, and changes in temperatures can alter the patterns of migration or food supply of various species and other species will have to make changes in their survival tactics that are usual.
By preserving forest ecosystems, wildlife is able to sustain the natural seasonal adaptation. With the healthy and undisturbed forests, animals are able to proceed according to their evolutionary patterns with which they have managed to endure seasonal changes in the environment over centuries.
