How might bird populations on mountainsides respond to a warming climate?(1 point)
Responses
a.Their eggs will hatch later.
b. The range shifts downhill over generations.
c. The range shifts uphill over generations.
d. There is not likely to be an effect based on a warming climate.
c. The range shifts uphill over generations.
As temperatures warm, bird species may respond by shifting their ranges towards higher elevations to find suitable climatic conditions. This process may take several generations, as birds that are more adapted to higher elevations will likely have better survival and breeding success. However, some bird species may also face habitat loss and other threats due to changes in precipitation, availability of food, and competition with other species.
c. The range shifts uphill over generations.
To determine how bird populations on mountainsides might respond to a warming climate, we can consider the concept of elevational range shifts.
Elevational range shifts refer to the movement of species to different elevations in response to changing environmental conditions, such as temperature. When it comes to a warming climate, there are two potential responses that can be observed in bird populations on mountainsides.
Option c. The range shifts uphill over generations: One possible response is that bird populations may shift their range uphill over generations in response to a warming climate. As temperatures increase, the suitable conditions for certain bird species may move further up the mountainside. This can result in populations of these birds gradually occupying higher elevations over time.
Option b. The range shifts downhill over generations: On the other hand, some bird populations may actually shift their range downhill over generations as a response to a warming climate. This can occur when the warming climate makes higher elevations less suitable for certain bird species and forces them to move to lower elevations where conditions are more favorable.
Therefore, the correct answer to the question would be either option b or c, depending on the specific bird species and the magnitude of the warming climate. The other options, a and d, are not accurate because a warming climate is likely to have an effect on bird populations on mountainsides.
