Chapter 56.1, Problem 1CS
Summary Introduction
To explain: The dispersion pattern of cheetahs in the wild.
Introduction: A territory is defined as a fixed area which is defended by an individual or a group of individuals from the other member of its species. Many animals have their territory such as lion, cheetah, dogs and so on.

. 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?

when an aerial predator was sighted, and terrestrial refers to calls given when
a terrestrial predator was sighted. Recruitment calls prompted feeding

- Do 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_forward1) 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_forwardWhat are three aspects of your lifestyle that might directly or indirectly contribute to declines in European honeybee populations and the endangerment of other pollinator species (Core Case Study)?arrow_forward

The search efficiency parameter (a) represents how quickly the predator finds and kills its prey. What would happen if most the predator population had a parasite that made them less effective predators? Infected animals find and kill prey less frequently (that is, the parasite caused the value of the search efficiency parameter to decline). the populations would still cycle; the amplitude of prey and predator would increase Othe populations would no longer cycle; the prey would increase and the predator would go extinct the populations would no longer cycle; the prey would go extinct and the predator would increase the populations would still cycle; the amplitude of prey and predator would decline the predator and prey populations would no longer cycle; the parasite and the predator populations would cycle insteadarrow_forwardBased on these graphs, and assuming head raises of European finches helps watch for predators but also has a trade-off with eating, select the statements that these graphs support.
