Winter adaptation for animals is one of the ways these animals follow to preserve their lives in light of the harsh weather conditions they live in, as this season is considered one of the harshest seasons that directly threatens the animal’s life, whether in terms of low temperatures, accumulated snow, or strong air currents.
Therefore, we see these animals starting to take some preventive measures for such conditions, which are represented by amazing strategies that work to adapt them to these harsh conditions to show everyone an exceptional ability that urges environmental and animal scientists to study it and learn about its merits from all aspects.
In this article, we will present a general invitation to everyone to learn about the amazing ways that animals follow to overcome these harsh conditions and survive. Let us begin our journey into the depths of wildlife.
What is winter adaptation?
Winter adaptation in animals can be defined as a group of biological and behavioral changes that occur in the life of the animal to enable it to survive throughout the harsh winter period. These changes include a group of strategies, which are represented by their biological activity in terms of an increase in the thickness of the fur or feathers to confront the cold. Winter, in addition to its general behavior, whether it enters the hibernation phase, which provides it with energy, or undertakes the process of migrating and moving to warmer areas.
Nutrition is also considered one of the strategies that animals follow to adapt to the cold season, as it works to store food in seasons of abundance or change the diet to replace it with materials available in the winter, and this leads to physiological changes in the animal itself, such as the production of fats to improve thermal insulation or reduce heat loss. the heat.
The importance of winter adaptation:
Winter adaptation of animals is one of the important points necessary to ensure their survival. Without these strategies, these animals will find themselves unable to withstand the harsh conditions in the cold season, and this will greatly affect their chances of survival.
Types of challenges animals face in winter:
Animals face many challenges that directly affect their lives, which are as follows:
Low temperatures, as maintaining them requires additional effort and energy, in addition to effective means of thermal insulation.
The lack of nutrients necessary for them, whether in terms of plant decline or a significant shortage of prey.
Environmental changes, which are represented by snow and ice covering large areas, which makes transportation and movement difficult.
Increasing the potential risks to the lives of animals from predators that exploit such situations to kill them.
Examples of animal adaptation in cold regions: What are behavioral adaptations in winter:
In winter, animals follow some strategies that adapt them to the harsh conditions of the cold season. These strategies are as follows:
Hibernation:
It is a condition that animals enter during the winter to survive. This technique works to preserve the energy needed for the animal, which the low temperatures and the great shortage of food resources cause it to consume, so its metabolic rates decrease, the body temperature decreases, and the number of heartbeats decreases. The heart and breathing slow down.
Immigration:
Some animals follow this strategy to escape the unbearable cold of winter, so they work to move to areas that are warmer and have the basic requirements for survival.
Physical changes:
Some biological changes occur in the animal’s body, which are represented by an increase in the thickness of the fur or feathers, in addition to an increase in fat, which helps improve the body’s thermal insulation or reduce the loss of its body heat.
Food storage:
Some animals take advantage of seasons of abundant food and work to store it in effective ways to benefit from it during times when food is scarce. This is one of the techniques that animals work to exploit to ensure their survival.
Behavioral adaptation:
This strategy is one of the most important strategies that animals use to ensure their survival, as they can stick together to form large groups that work to maintain their temperature, like penguins or honey bees, and they can also reduce their activity to the lowest level. To preserve the energy needed for them, whether by reducing their heart rate and decreasing the breathing process or lowering their body temperature, like bears and squirrels.
Examples of distinctive animals and their winter adaptation:
Wildlife provides many examples of the winter adaptation process for animals, the most prominent of which are the following:
Penguin:
The penguin has amazing strategies that ensure its survival in cold climates, as the fat accumulated under the skin and the thick fur protect it from the cold. In addition, the penguins create a large colony that includes large numbers of them that join together and gather to maintain their temperature during snow storms. By moving constantly to ensure that everyone gets a chance to be in the warm center.
Arctic foxes:
Foxes change the color of their fur to white to camouflage themselves in the snow to help them hunt, which changes according to suitable weather conditions. They also work to increase the thickness of the fur that covers their bodies and accumulate fat under the skin to help them withstand the cold during the winter. They also work to dig warm dens for themselves and reduce Their general activity during periods of peak cold, all of which serve as strategies that ensure the survival of these animals during the winter period.
Fish in frozen lakes:
Survival techniques for fish in frozen lakes include:
Reducing metabolism, which reduces their food and energy levels.
It forms anti-freeze proteins that allow it to protect its cells from freezing and thus keep them alive.
Fish move to deeper areas where temperatures are more stable and higher than the surface water temperature.
Fish hibernate in the winter to adapt to the lack of food resources.
Fish reduce their oxygen consumption by controlling the breathing process. This is called slow breathing.
polar bears:
Polar bears have many techniques that greatly help them cope with the extreme cold during the winter. The most prominent of these techniques include the following:
An increase in the thickness of the fur that covers its body, in addition to the fact that polar bears have black skin under the fur, which helps in absorbing the heat of the sun greatly, and this helps raise the body temperature.
An increase in the layers of subcutaneous fat, as these layers contribute to the formation of ideal insulation during the period of extreme cold.
Building snow dens that help her protect herself and her children from the cold in the winter.
Searching for food whenever they have the opportunity, as the polar seal is one of the most available foods, as seal fat is one of the foods that contributes to providing a large amount of energy and warmth.
Polar bears live alone throughout the winter, which reduces competition for food resources in a cold environment.
Challenges of winter adaptation and the impact of climate change:
Winter adaptation in animals faces many challenges, and climate change is considered one of the most prominent of them, as climate change changes some of the technologies that animals have naturally adapted to, and among those changes are the following:
The timing of migration and hibernation in some animals, as temperatures play the most important role in the timing of migration and hibernation in animals, and any change in their rates directly affects them, and this exposes them to unexpected harsh conditions and thus reduces their chances of survival.
Increased metabolic rates, as some animals depend on the fat they have stored throughout the summer to face the cold of winter. Therefore, it is possible that some animals find themselves unable to tolerate some conditions in light of the long, warm winter periods.
The warm winter plays an important and major role in the rate of snowfall, which some animals depend on to survive throughout the winter. For example, there are hares that depend on snow cover for camouflage and protection from predators that may affect their lives. Polar bears also depend heavily on Ice hunts seals, which they live on throughout the cold winter.
Therefore, we must pay attention to the importance of maintaining the environmental balance that works to ensure the survival of these animals, as this is done by reducing gaseous emissions and protecting habitats by establishing natural reserves that work to preserve the areas that constitute a safe haven for animals throughout the winter period. In addition to increasing environmental awareness for children and youth, to highlight its importance in preserving the natural environment of many animals.
