The recent loss of biodiversity on Earth stems from _______.  

In a mature forest, adult trees cast a deep shade that prevents pioneer species of plants from surviving. This mechanism of succession would be considered _____.  

Interactions between species can increase or decrease the diversity of a community, usually measured as the number of species. For each type of interaction, state whether the interaction (i) increases diversity, (ii) decreases diversity, or (iii) either increases or decreases diversity depending on the situation. Defend your position based on direct and indirect effects in a community. Four types of interactions: Competition (2.0 pts) Herbivory (2.0 pts) Mutualism (2.0 pts) Predation (2.0 pts)

While out hiking you observe two beetle species (i.e., beetle species A and beetle species B) feeding on a single species of plant (i.e., Shrub C). Consider the Competitive Exclusion Principle for the two beetle species, which states that two species cannot coexist indefinitely when they are both limited by the same resource. Describe an experiment that you could perform to test if the two beetle species (i.e., beetles A and B) feeding on the shrub (i.e., shrub C only) fit this principle. Include a brief description of two treatments and one control, as well as a variable you will measure to help determine the outcome (4.0 pts). What pattern(s) do you predict to observe if your experiment of the Competitive Exclusion Principle is supported? Explain your reasoning (4.0 pts). What pattern(s) do you predict to observe if your experiment of the Competitive Exclusion Principle is not supported? Explain your reasoning (4.0 pts).

A researcher studying a population of antelopes developed the life table shown below. Use this table to answer the following questions. Life Table Age sx bx 0 0.4 0 1 0.3 0 2 0.9 1 3 0.8 3 4 0.1 2 5 0.0 0   What is the survivorship of an individual from birth to the age of 4 years? (4.0 pts) must show work to receive full credit. What is the net reproductive rate of the population? (5.0 pts) must show work to receive full credit. Do we expect this population to increase, remain relatively the same, or decrease? Why? (3.0 pts) describe both numerically and with text. must show work to receive full credit. To ensure accurate grading, label the three question a, b, and c in your answer.
