- What is the value of being able to estimate thre size of a population? (For example, the Bluefin Tuna Population)? White- tail Deer)?The neighborhood of a lake has a population of snails, which come out onto the sidewalk when the sprinklers come on, and the rest of the time they hide in the vegetation. If you catch 20, and mark them and, then, a week later, after they have had a chance to disperse into the population, you catch 15, and 6 have marks on them, what is the estimated size of the population?Why are population sizes not constant in biology?
- Using grey squirrels as an example, describe a population that would be of interest to a researcher. How would your approach to squirrels differ if you were going to measure tail length on a sample vs doing a census? Using white tailed deer as an example, describe a population that would be of interest to a researcher in Central Illinois. What variable might be of interest?If a population of squirrels is 245, has a BR of 34/year, DR of 28/year, IR of 82/year and ERof 2/year, what would be the GR? What would be the population at the end of one year? Showyour work.Is the wolf population controlled by density or density-independent factors? Explain using one piece of information from the reading to support your choice. You should use those supports to back up your choice, that is, how did this piece of support lead you to your answer.
- Given that white-tailed deer give birth to fawns each spring, which population growth model would be the most appropriate and why?A population has 1000 juvenile individuals, 100 young adult individuals, and 10 older adult individuals. This population is likely…? Group of answer choices a, increasing b. decreasing c. stable d. no way to tellHow do you calculate N (population size)? Is the mark-recapture method a reliable way to estimate population size?
- How many lions do you think there are in 1960 and 1975? Why do you think the population is the size you predicted?Two populations of deer live in similar protected tracts of land. In tract A, the deer are left to forage on their own. In tract B, the villagers start providing supplemental food in the winter. What would you predict about the two populations after a few years and why? Draw a graph to show your predictionsYou have been put in charge of managing a population of the endangered pink fairy armadillo. The population is currently 500 (N=500). What kinds of information would need to have to determine how big the population will be in 10 years? What environmental influences might influence the accuracy of your prediction?
