Question

Consider the following scenario: A drought hits the habitat of a semi-aquatic bird population. All ponds

dry up, and fish populations decline. There are two groups of birds in the population that differ in leg
length and diet. Long-legged birds eat insects. the drought has little effect on the insect populations.
What is the main selective pressure in this scenario?

Insect population

The main selective pressure in this scenario would be the drought. The drought is causing the ponds to dry up, leading to a decline in fish populations and potentially limiting the access to water for the semi-aquatic bird population. This would impact the survival and reproduction of the birds, putting pressure on their ability to adapt to the changing environment.

In this scenario, the main selective pressure would likely be on the fish population. With the drought causing the ponds to dry up and fish populations declining, this would affect the availability of food for the semi-aquatic bird population that depends on fish as part of their diet. The birds that rely on fish for their diet may face challenges in finding enough food to survive and reproduce, ultimately impacting their fitness and ability to pass on their genes. This selective pressure on food availability (fish population) would be a significant factor influencing the population dynamics and evolution of the bird population in this scenario.
