8.
. Simulations 4-6 had lower density of birds (more spacing), how did this influence their ability to escape predation? With more spacing, which number of Junco’s was most advantageous (4, 8, and 16)? Ecologically explain this result.
If this flock of birds occurred in an area with low food availability what flock density would you predict? Explain how food availability impacts flock size/competition.
Was there a relationship between prop. Vigilance (proportion of birds looking up right before Hawk attack) and the rate at which they escaped predation?
Was there a relationship between Mean vigilance (average number of birds looking up each tick) and the rate at which the Junco’s the escaped predation? Was there a relationship between Mean vigilance and the number of birds in the flock?
Is this correct??? or is it the other way around

- 1) Think back to the example of ovenbird evoluon in South America. Ovenbirds are a diverse family of small, insect-eang birds that live mainly in South America. Different ovenbird species have adapted to rocky ocean shorelines, snowy mountains, scorched deserts and tropical rainforests. Like finches, ovenbirds have a variety of beak sizes and shapes, an important indicator of food preference that makes them ideal for studying evoluon. In ovenbirds, "some [beaks] are long and down-curved, like a scythe, for probing into crevices in tree bark and others have short dagger-like bills." What conclusions did the researchers reach? A) ovenbirds are diverse because they do not share any common ancestors B) ovenbirds because successful because they are not native to the area and could easily colonize the area C) birds have different beaks that help them exploit different resources and avoid competition 2) One ant species from Africa is best at competing for space, but is worse at colonizing a…arrow_forward1.

- Endler (1980) set up two experiments, one in the greenhouse and one in the field to test the influences of mate choice and predation in determining colorfulness of male guppies. Identify the roles of mate choice and predation in determining colorfulness of male guppies. Identify the advantage and shortcomings of the greenhouse experiments. Identify the advantages and shortcomings of field experiments along the Aripo River. Identify other factors, especially physical and chemical factors, might influence male color.arrow_forwardDo the following two hypothesis supports their graphs? Explain. Figure 1: The hypothesis for novice vs. experienced foraging is that animals who have been foraging for ages should have a greater chance of survival than beginner foragers since they are more skilled and invest less time looking for food. Figure 2: The hypothesis behind the impact of Prey camouflage is that if animals, especially novice foragers, take too much time searching, they are visible to predators for long durations, providing a better chance to attack.arrow_forwardWhat is the best description of the original Lotka-Volterra predator-prey model?

- Comparing across animals in the image, do you think there is a major difference in the animals' abilities to solve complex problems like mazes, tool use, etc.? Why or why not?arrow_forward12) Currently, the only predators of Galápagos marine iguanas are Galápagos hawks. Iguana body size is not correlated with risk of hawk predation, although small iguanas can sprint faster than large iguanas. If predators (e.g., cats) that preferentially catch and eat slower iguanas are introduced to the island, in the absence of other factors; the iguanas would then be under iguana body size is likely to selection.

Females excavate tunnels beneath fresh dung piles where they mate with the males, and then lay their eggs.
