So, let's turn our attention to some of those population dynamics! Suppose we studied two populations of diatoms and determined the following parameters: Age (Days) X 0 1 2 3 4 5 Cyanobacteria Survivorship Fecundity (1x) (mx, a.k.a. fx) 1.0 0 0.95 0 0.90 1 0.85 1 0.5 0 0 Dinoflagellates Survivorship Fecundity (1x) (mx, a.k.a. fx) 1.0 0 0.15 0 0.10 0 0.05 20 0.025 40 0 a. Which population is growing at a faster rate? Please back up your answer with calculations. Round to two decimal places. [Brief Explanation and Calculations, including units, round the second decimal place) - 5 Points b. Now suppose Dinoflagellates are at a population size of 480 individuals per mL. Unfortunately, at some point they will start to be limited the nutrients in the water. If they are in marine systems, they are more likely to be limited by what? If they are in freshwater systems, they are most likely to be limited by what? [2 Words) - 5 Points c. We know that when they reach 1680 individuals per mL they will have reached their carrying capacity. How many days will it take them to reach their carrying capacity? Calculations and Brief Explanation, including units, round to the nearest day) - 5 Points d. Oh no! The cyanobacteria are loose. Somehow, a small population of 10 individuals per mL got into the water with the dinoflagellates. We know they are good competitors when nitrogen is limiting. In fact, their competition coefficient is 0.75 (the effect of cyanos on dinos), while the dinoflagellates competition coefficient is 0.25 (the effect of dynos on cyanos). Cyanobacteria can reach a population 2500 individuals per mL before hitting their carrying capacity. What will the short-term and the long-term outcome of this battle be? Provide your state space diagram. Calculations, State Space Diagram, Short-term and Long-term Outcomes] - 5 Points e. What type of competition are these two populations involved in?
