Cаse study: Flоridа Pаnther Flоrida panther, оur FIU mascot, are a type of puma, Puma concolor, which is a large predatory cat that roams in ecosystems from Canada, through the US all the way to the southern tip of Argentina. Florida panthers used to live throughout the southeastern United States. However, due to habitat destruction and hunting, pumas in the US have disappeared east of Mississippi River. Only one small Eastern population remains, isolated in South Florida. Conservation efforts require that we know whether the Florida panther is a separate species or whether it can still be considered Puma concolor. Which of the following tests will allow you to determine it still belongs to the species Puma concolor under the Biological Species Concept?
Cаse Study: Dаrwin's Finches In 1977 the Gаlapagоs had abnоrmally lоw rainfall, and the seed plants on which the medium ground finch, Geospiza fortis, depend produced small crops. Only 15% of the population survived the drought, and the survivors were the mostly large birds with strong beaks, because they were able to crack large seeds. The population as a whole was shifted toward larger body size. The level of selection measured in the drought and the drastic population crash was the highest yet recorded in a vertebrate population. However, a few years later there was a particularly wet year, and enormous quantities of seeds were produced. The finches had multiple broods that year, and smaller individuals, having great numbers of small seeds available, and reaching maturity faster, raised more offspring. The effect of the wet year was to shift the average body size back toward smaller size. Similar major fluctuations in climate and food supply occur on approximately a 20-year spacing in the Galapagos as El Nino and La Niña perturbs the local climate, producing dry and wet years. Imagine if instead the island continuously produced large and small seeds at the same time. Overtime, the population of finches would split into two, one with larger beaks specialized in large seeds and the other with smaller beaks specialized in small seeds. What type of selection called?
In а pоpulаtiоn оf 800 fowls thаt are either black or white, black color is dominant to white color. Of this population, approximately 125 individuals are white. Assuming that the population is at equilibrium for this gene/locus, answer the following. Part A: Calculate the allele frequencies and genotype frequencies (p,2pq, etc.). Perform all calculations to three decimal places. (Note: you will NOT be scored on part A, but your work in part A, will be required to do Part B.) Part B: BONUS: After the previous predictions were made, actual samples were obtained from all individuals in the population described above. Genetic analyses were done, and it was found that of those that were black, 430 are homozygous dominant and 245 are heterozygous. Is the population above at equilibrium? Use the chi-square test to determine this. (The chi-square formula and chart is shown below the questions for convenience.) Answer the following: 1. What was the chi-square value? 2. What was the df (degree of freedom) that you used? 3. Did you accept or reject the hypothesis? Why? 4. Is the population at equilibrium? Why or why not?
