A population of wolves in a national park is known to be 150 individuals. As wildlife ecologist, you are tasked with assessing the accuracy of the mark and recapture technique. At the start, you mark 30 wolves, and your recapture yields 20 wolves, 5 of whom are marked. State whether the mark and recapture data results in an over or underestimation of the actual population size, and show work to support your claim.

Which of the following is a conclusion drawn by the authors from the results of this study?
Temperate marine invertebrate species are outcompeting endemic species which will soon become extinct in the surveyed areas.
Tropical marine invertebrate species did replace temperate species from 1982 to 2021 in the surveyed areas.
Tropical marine invertebrate species did not replace temperate species from 1982 to 2021 in the surveyed areas.
The temperate marine invertebrate species density and richness will recover with sufficient monitoring and resources.

You have been researching the biodiversity of different species of lizards in the Florida Everglades. You select a one square acre plot of land and begin tagging and counting the different reptiles found in that area over 6 months. After 6 months of research, you collected the following data:
Species
Count
Green Anole
16
Brown Anole
72
American Alligator
3
Burmese python
2
Corn Snake
9
Eastern Glass Lizard
8
Use the blanks below to answer the following questions:
1. What is the biodiversity index of the one acre lot observed?
2. If you collected the same information for a second square acre 10 miles away and determined that acre to have a biodiversity index of 0.37, would you consider the first area to be biologically diverse and why or why not?
3. What do you think is suppressing biodiversity in the first acre counted?
