A new species of toad is introduced into a region in a shipment of fruit, survives, and manages to start breeding. How could you determine whether the toad was an invasive species? You would need to determine whether it started breeding with native species. You would have to see if it was present over a large region or if it stayed in one location. All nonnative species are invasive species. You would need to watch over time to see if it had a negative effect on other species. As it is now breeding in the area, it would be considered native and not invasive.

The Grants have studied finches on the Galapagos Islands for 40+ years. During times of drought, there is less green/flowering vegetation available as a food source for the finches. This leaves only the hard, thorny seeds. The Grants have found that during drought, finches with larger beaks survive at a higher rate because they can access the food source. This would be an example of __________. a. good genes hypothesis b. selective pressure c. handicap principle d. population variation

In a population of mayflies, variation in the STRIPE gene causes different body coloration. SS individuals have skinny stripes, Ss individuals have wide stripes, and ss individuals are unassigned. You collect some mayflies and estimate that the frequency of the S allele is 0.85. You want to know whether the population is evolving, so you will return to the same site next summer and collect 1000 mayflies from the next generation. If the population is not evolving, how many of the 1000 mayflies collected next summer should have wide stripes. (round to the nearest whole number) A. 255 b.850 C. 723 D. 23
What is an example of how migration causes changes in gene frequencies? Genetic material can become lost over time due to lack of reproduction when animals migrate. When animals migrate, their genes mutate on their own, changing the frequency that a gene allele shows up. When animals migrate, the mating becomes less random, causing inbreeding and, therefore, shifts in the proportion of alleles. Seeds of plants are carried to different locations and introduced to a new population, adding their own genetic material and, therefore, changing gene frequencies.
A small number of animals moves away from a large ancestral population on the continental mainland and colonizes an island. Which of the following is likely to occur? A. Genetic diversity will decrease on the mainland, because of a population bottleneck. B. Alleles that were more rare on the mainland are likely to become more common on the island, because of the founder effect. C. Genetic diversity will be lower on the island than the mainland, because of the founder effect. D. Mutations rates will increase on the island, in response to selection pressures in the new environment.
Which of the following would likely not be a result of character displacement? A: The competition between 5 beetle species living in the same area is lessenedB: One of the four bird species on an island goes extinctC: Coevolution of plants and pollinatorsD: Two lizard species in the same area evolve the ability to feed on different insects
A small population of birds lived on an island. They were all the same species and ate a large variety of foods. This population had a lot of variation in beak size and shape. Over time, the population of finches grew pretty large. Some individuals in the population had slightly longer and thinner beaks. These individuals could forage for insects in the holes in trees in ways that the others in the population couldn't. They left more offspring that had that trait and over time, created a new species that foraged exclusively on insects in trees. This process is called: speciation. endemicism. All of the answers are correct. acclimatization.
Which of the following terms best describes the biological scenario where species that look similar in allopatry look different in sympatry? a. Character displacement b. Tempo c. Fusion d. Post-zygotic barriers
A subpopulation of a species of birds migrates to a different location from the rest of the species for breeding purposes. How might the genes change in the subpopulation? A. Their genes would change randomly and eventually revert to normalcy, which would allow the subpopulation to return to the main population. B. Their genes would change to better allow them to survive and reproduce in their new location. C. Their genes would not change at all and they would merely be a subpopulation living in a different location. D. Their genes would change so that they would continue to be well-adapted to their former location.
Is there evidence that random genetic drift in the inbred Swedish population had led to a decline in mean fitness that was sufficient to cause the extinction of the population? Here, I am asking about the Swedish population before the outbred snakes were introduced. What is the evidence for a decline in mean fitness, if you believe this happened?
Imagine that you are asked to manage a population of wolves that have taken upresidence on an island off the coast of Alaska. Because prey resources are limited, theisland will support only about 50 wolves at any one time. What steps would you take toprevent inbreeding and genetic drift in the population in the future?
How does protecting the biodiversity of an area increases the survival of a species’ population? Use the principles of threats to biodiversity (e.g. overexploitation, habitat loss, invasive species, etc.), species dominance or evenness, and genetics of the species (e.g. inbreeding, mutations, founder effect bottlenecks, etc.). Use a Philippine endemic species as an example in your answer.
