WRITE ABOUT A THEME: INTERACTIONS In Batesian mimicry, a palatable species gains protection by mimicking an unpalatable one. Imagine that individuals of d palatable, brightly colored fly species are blown to three remote islands. The first island has no predators of that species; the second has predators but no similarly colored, unpalatable species; and the third has both predators and a similarly colored, unpalatable species. In a short essay (100-150 words), predict what might happen to the coloration of the palatable species on each island through time if coloration is a genetically controlled trait. Explain your predictions.

- I’m not sure how to approach this problem can you explain how to get the answer?arrow_forwardThink about a predator-prey system that perfectly follows Lotka-Volterra dynamics. 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_forwardThe competitive dominance hierarchy (left) and food web (right) diagrams below show simplified species relationships for a large meadow habitat in the midwestern United States.

- Question:- Identify at least 4 different cause that are used by migratory animals to find their way during migration. Then, pick one of the cause and explain how we know that at least one species or organism uses these cues.arrow_forwardforest sites than in forest fragments, whereas there were no significant differences between fragments of different sizes. These results provide further evidence for the effects of habitat size on the phorid-Acromyrmex system in a tropical rain forest, based on the abundance of parasitoids both as adults in the field and as reared immature phorids in the laboratory. Phorid parasitized leafcutter ants were most abundant in areas of continuous forest, and less abundant in the forest fragments. O Phorid flies are important parasitoids of leafcutter ants nd leafcutter ants can be found in Brazil's Southeastern Both phorid flies Atlantic Forest. The study provides evidence that this parasitoid-host interaction between phorid flies and leafcutter ant differs between continuous forest and forest fragments. Phorid flies were just as abundant in forest fragments as they were in continuous forest, but were less successful in parasitizing leafcutter ants.arrow_forwardConsider two bird species that forage for insects that live in shrubs. The shrubs have a clumped, patchy distribution throughout their habitat. The two bird species have the same ability to locate, capture, and consume the insects. However, one species (species A) uses less energy to fly from patch to patch than the other species (species B). According to the marginal value theorem, which bird species should spend more time in each patch, and why?arrow_forward
- Which of the following statements most accurately describes the example of species interactions for ants, plants and aphids Question 2 options: The burdock plant is negatively affected by a heavy aphid investation, the ants are negatively affected by the aphids and aphids are positively affected by the ants. The burdock plant is negatively affected by a heavy aphid investation, the ants are positively affected by the aphids and aphids are not affected by the ants The burdock plant is negatively affected by a heavy aphid investation, the ants are positively affected by the aphids and aphids are positively affected by the ants. The burdock plant is not affected by a heavy aphid investation, the ants are positively affected by the aphids and aphids are positively affected by the ants.arrow_forwardAfter spraying your yard with a weed-killer you notice that you don't see any bees in your yard for the next few days. You know that bees are a keystone species that is critical for a healthy environment, and want to investigate if there is a connection between the weed-killer and the absence of bees. Task: Design an experiment that could test this association by describing each of the following points with a sentence: Describe your hypothesis: Describe your dependent variable: Describe you independent variable: Describe your positive control group: Describe a negative control group:arrow_forwardI need help identifying which assumption of Hardy-Weinberg equilibrium is most affected, then indicating whether what is being described will act to establish or violate equilibrium, and lastly, whether the statement will increase or decrease that population’s genetic variation. Corals synchronize spawning to occur on a single night during a particular tidal event, such as a spring tide. On that night individuals release sperm and eggs into the water, which then form zygotes. Larvae are carried off by currents and settle elsewhere. What assumption is this breeding style affecting and what will it do to VG of that coral species?arrow_forward
- A niche is loosely defined as an organism's role in its environment, which can include factors such as feeding preference, nesting behaviors, mating behaviors, method of obtaining prey, and local habitats. Keeping Gause's law in mind, do some research on the California red-legged frog and the North Pacific tree frog (use wiki or another Google search). Create a chart comparing the two with respect to their niche or lifestyle that can explain how these two frogs can co-exist in the same ecosystem.arrow_forwardDirection: You must Answer no.1 to no. 5. Identification only. No need to explain each answer. Provide correct answer to each question. Zoom in the picture in order to see it clearly. It's not incomplete. Thank you in advance.arrow_forwardWhat is the Predator Release Hypothesis? Explain how it works. What is ONE principle or idea that we studied in this course that can be illustrated using it (other than predation). Explain how the predator release hypothesis fits into that idea.arrow_forward
