- Consider the graphic that is presented and depicts the end-point for the following scenario. At some point in the past, species A resided as a large population entirely within a rectangular geographical area. The population became divided into two isolated populations when, during a major earthquake, a mountain range arose and disrupted gene flow. Over time, the two new populations evolved independently from one another, yielding species B and C. The population comprising species C became divided into two isolated populations when another earthquake created an escarpment that disrupted gene flow. Over time, these two new populations evolved independently from one another, yielding species D and E.Imagine that you were to arrive to the region long after species D and E had evolved, completely oblivious to the scenario that is described above; survey the region for living species in this group; and conduct a cladistic analysis on those species. Assuming that the data that you were to…Place a species distribution in order from smallest to largest. Group of answer choices Geographic range < Population < Metapopulation Geographic range < Metapopulation < Population Metapopulation < Population < Geographic range Population < Metapopulation < Geographic rangeConsider the following scenario. A large population of lizards occupies an extensive range that is relatively uniform ecologically (i.e., in terms of climate and co-occurring species). At a certain point in time, the ancestral population becomes divided down the middle into two similar-sized portions by a barrier that completely prevents the movement of lizards between the descendant populations. Around the same time, a major flood occurs, and a small number of individuals have swept away from the mainland on floating debris and arrive alive on a small offshore island that has no lizards of this species. The habitat on the island is similar to their homeland, but not identical (the climate is slightly different, many mainland species of plants and animals are absent, and a few island species of plants and animals are different from any present on the mainland. Thus, there are now three separate populations. Compare and contrast the expected evolutionary consequences for these…

There are approximately 1,100 frogs on Island 1, 400 on Island 2, and 400 on Island 3. Researchers estimate that these populations have been separated for 800 years. Individuals in these populations show variation in markings on their body by shape and color. Frogs on Islands 1 and 2 have circle markings that are either red, blue, or purple. All frogs on Island 3 have yellow triangle markings. The islands recently became a tourist destination, with new passenger boats connecting Island 1 and Island 2, and Island 1 and Island 3 (there is no boat that goes between Island 2 and Island 3).

- Please answer fast In an allopatric speciation model, we would expect A Strength of reproductive isolation to increase with increased time in isolation B.Strength of reproductive isolation to increase with decreased time in isolation C .Strength of reproductive isolation to be unrelated to time in isolation D .Strength of reproductive isolation to decrease with increased time in isolationGive typing answer with explanation and conclusion Scientists are trying to estimate the size of a bird species whose local population is 325. Since they cannot see all 325 at once, they will estimate it using mark-recapture methods. They initially capture 64 individuals, mark them, and release them. They then recapture 50. What is the most likely number of MARKED birds in their recapture sample? (You may need to round up or down for the correct answer.) Multiple Choice -50 -1 -10 -5 -0 -253Which of the following is NOT an example of an r-selected population? Select one: a. Mosquito lifespan is between 42 and 56 days for females and 10 days for males. b. Minnows spawn 16 to 26 times per year, yielding up to 10 000 eggs per female. c. Houseflies are very tolerant of a wide range of environmental conditions and thus have a broad range of habitat. d. Algae are capable of reproducing asexually and sexually to take advantage on the conditions of the environment.
