Polar bears hunt for ridged seals by waiting for them to emerge from breathing holes in the Ice which abiotic change may decrease a polar bears ability to hunt
Increased ice cover
Increased temperatures
Increased competition
Increased seal population
1. Increased ice cover: If there is an increase in ice cover, it can make it more difficult for polar bears to locate breathing holes in the ice. This reduces their ability to wait by these holes and hunt seals effectively.
2. Increased temperatures: As temperatures increase, the ice in the polar bear's habitat may melt and break up more quickly. This can lead to a decrease in suitable ice platforms for hunting, as well as making it more challenging for polar bears to access breathing holes.
3. Increased competition: If the polar bear population increases or if there is an influx of other predators, such as orcas or walruses, it can result in increased competition for limited resources. This includes competition for access to breathing holes and seals, making it more difficult for individual polar bears to successfully hunt.
4. Increased seal population: Surprisingly, an increased seal population can also impact a polar bear's ability to hunt. If there are more seals available, it may seem like an advantage for polar bears. However, an increase in seal population can also lead to more seals spreading out across the ice, making it harder for polar bears to locate and catch them.
Overall, these abiotic changes can have a detrimental impact on a polar bear's ability to hunt effectively and obtain sufficient food. This can result in reduced body condition, reproductive success, and overall survival of polar bear populations.
