Detailed explanation-1: -Different mating rituals can lead to isolation. One example is birds singing different songs to attract mates. Other examples include different preferences in breeding calls, mating dances, and pheromones.
Detailed explanation-2: -Behavioral isolation occurs when the presence or absence of a specific behavior prevents reproduction from taking place. For example, male fireflies use specific light patterns to attract females.
Detailed explanation-3: -“Species of fish living in different areas of a pond due to differential salt concentrations” is not an example of behavioral isolation because there is not difference in mating behaviors that reproductively isolates the two species of fish.
Detailed explanation-4: -Behavioral isolation occurs when mismatches in mating traits (signals and/or preferences) prevent mating between two species/populations.
