Q6.7. How will the population of birds change over the first few years? The population will grow steadily, gaining a constant number of birds each year. The population will grow more and more rapidly with each passing year. The population will grow steadily for a few years and then shrink steadily back to zero. The population's growth in the first few years will depend on the size of the city.

In one year, there were 18 males and 34 females. Over the following year, each female gave birth, of which 28 survived. Nine elephants died due to predators. A construction project cleared 50 acres of nearby forested land, causing 5 males and 19 females to immigrate into the experimental area. Competition for females increased, resulting in the emigration of 10 males to a new territory in search of mates.
Many species of birds have elaborate mating rituals that include bird calls, nest construction, and courtship displays. A researcher is comparing two populations of birds with similar morphology that live in similar niches. Male birds in one population build a nest before attempting to court a female, while males in the other population build the nest in cooperation with the female. Is it likely the researcher will classify these birds as the same species?
In populations subjected to high levels of predation a. individuals should invest little in reproduction so as to maximize their survival. b. individuals should produce few offspring and invest little in any of them. c. individuals should invest greatly in reproduction because their chance of surviving to another breeding season is low. d. individuals should stop reproducing altogether.

Tests on wild cheetahs have shown that there is low genetic diversity among individuals. Wildlife biologists and conservationists are worried about what this means for the survival of this species. Why is low genetic variability a big problem when it comes to a species survival in a changing habitat?

A dairy farmer chooses to mate a male bull only with the female heifers that always make the greatest amount of milk, rather than heifers that produce a small amount of milk. What process is the dairy farmer employing when producing the next generation of calves?
Most remote oceanic islands have at least one unique species of flightless bird that shows little or no fear of humans or other large predators. Account for this observation.
In a population of birds, males have long red tail feathers that they use in mating displays, and also sing in the mornings to attract females. You find that some males have more red feathers in their tails than others, while some sing for longer periods of time. In this bird species, a high proportion of eggs fail to hatch. You measure the number of eggs that successfully hatch that are fathered by each male bird, and find that the number of successful hatchlings is proportional to how long a male sings, but is unrelated to the amount of red in his tail. Question: Propose an explanation for why males evolved both to sing and to have red tails, and how females likely evolved in response to both traits. [Note: avoid writing a paragraph for each sentence prompt; this should still be short, concise answers and Please write four sentences guided by the individual prompts] Your answer: Sentence 1: State which males and which females had the highest fitness.
