Final answer:
To determine the total estimated Adélie penguin population in Antarctica, we can use the mark and release method. By knowing that the population on the Danger Islands represents 55% of the total population in the Antarctic Peninsula and the number of penguins on the islands, we can estimate the total population in Antarctica. Using this method, the estimated population is approximately 2,733,645.
Step-by-step explanation:
To determine the size of a penguin population in Antarctica using the mark and release method, a researcher would first capture a sample of penguins and mark them in a distinct way without causing harm. The marked penguins are then released back into the population. After a certain period of time, another sample is captured, and the proportion of marked penguins in the second sample is recorded. The total population size can be estimated by using the formula: Total population size = (Number of marked penguins in initial sample * Total population size of second sample) / Number of marked penguins in second sample.
In this case, we know that the estimated Adélie penguin population on the Danger Islands is 55% of the total population in the Antarctic Peninsula, and there are 1,503,054 penguins on the islands. We can use this information and the mark and release method to estimate the total Adélie penguin population in Antarctica.
Let's calculate it: Total population size = (1,503,054 * 100) / 55 = 2,733,644.727
Therefore, the total estimated Adélie penguin population in Antarctica is approximately 2,733,645.
