You are comparing species diversity between four different habitats: which of the following habitats is the most diverse? Habitat A has 15 species total, with approximately equal representation across all species Habitat B has 15 species total, and is dominated by two of its fifteen species Habitat C has 3 species total, with approximately equal representation across all species Habitat D has 3 species total, and is dominated by one of its three species Habitats A and B are equally diverse
Hyena carrying capacity in Mkomazi National Park is 500 (in the absence of competitors). Wild Dog carrying capacity in that park is 700 (in the absence of competitors). The addition of 1 wild dog to the park is equivalent to adding 2.5 hyena. The addition of 1 hyena to the park is equivalent to adding 0.4 wild dogs. Which of these species is the better competitor? Justify your answer quantitatively and illustrate your argument using an appropriate graph.

6a. Fill in the table below with the expected characteristics of r vs K selected species. r-selected species K-selected species Timing of maturation Longevity Parental care Number of offspring Size of offspring 6b. Based on your table, would a species that provides long-term parental care and has few offspring be considered an r-selected or K-selected species? What is an example of such a species? 6c. Why is long-term parental care associated with having few offspring during a reproductive episode?
You are studying two new species that have a mutualistic relationship. How would you determine if the mutualism is facultative or obligate? What types of observational data would you collect and what type of experiment would you conduct?
The figure shows the relationship between the growth rates (on a log scale) of individual fish and the similarity of the fish to their competitors. Assuming that populations with faster growth rates are more likely to have greater population growth, which principle or concept does the figure support? 4.0 3.9 드 3.8 3.7 -1.5 Least similar -1.0 -0.5 0.0 0.5 1.0 1.5 Most similar to competitors Morphological index to competitors O A. Competition is most intense when resources are scarce B. Competition can result in character displacement C. Competition is often asymmetrical D. Competition can determine the local distributions of species E. This figure shows no relationship about competition In (growth rate)
Based on the data in the table below, determine whether mutualism will evolve in Species 1 and Species 2.

One concept of conservation biology is known as minimum viablepopulation. Some species’ populations are so fragmented andsmall that they may have very little genetic variability left. Withminimal genetic variation in the population, there is little likelihoodthat a population can adapt to an environmental threat, such as anew disease. Florida panthers are at or below the minimum viablepopulation level (estimated population less than 80). 1)Do you think that it is practical to use limited resources toconserve a population like the Florida panther? 2)Why?
What would a random distribution of species in an environment indicate? that females are antagonistically interacting in the population that males are antagonistically interacting in the population resources are uniformly distributed throughout the habitat O resources are randomly distributed throughout the habitat
