- A particular specie of animal has a carrying capacity of K and a growth rate of r. From an initial population of N0, what will be its population after a very long time? Show your calculations.A population of boreal toads has a current size of 100 and time steps are measured in years. If the instantaneous rate of increase is 0.8 (toads/(toadXtime)), what will the expected population size be after two years? Note: You need to first figure out which equation to use for this problem. O 64 toads O 117 toads O 495 toads O 6400 toads No toads will be left because the instantaneous rate of increase is less than 1.0.1. Based on the graph, determine the population of carabao in:i. 4 years: _______ii. 5 years: _______iii. 6 years: _______2. What is the maximum carrying capacity of carabao in the given ecosystem?3. How many years did it take for the carabao to reach its carrying capacity? Explain your answer.
- 11.0 G. fortis 10.0- 1978 1976 9.0F 8.0 8.0 9.0 10.0 11.0 Midparent bill depth (mm) Geospiza is a genus of finches that inhabit the Galapagos Islands. In 1976, finches were grouped together based on the average depth of their bills. The data from the first generation of grouped finches are plotted on the X-axis. The bill depths of the offspring from each group are plotted on the Y-axis. In 1978, the experiment was repeated after a drought on the Galapagos Islands. The red line represents the data from 1976 and the blue line represents the data from 1978. The slope of both the red line is 0.90 and the slope of the blue line is 0.90. Was there any change in the heritability of the bill depth trait after the drought? Explain your reasoning. Offspring bill depth (mm)1.

Based on the graph, determine the population of carabao in: iii. 6 years:4. What is the maximum carrying capacity of carabao in the given ecosystem? 5. How many years did it take for the carabao to reach its carrying capacity? Explain your answer7) The following data has been obtained from the coastal haddock (Melanogrammus aeglefinus) fishery of Maine. The fishing season was divided into 10 periods. Period Catch per Period 1 208 2 195 3 168 4 132 5 91 6 80 7 63 8 56 9 48 10 33 It was also recorded that five fishing trawlers were in operation during each period of the fishing season. Question: What was the size of the haddock population originally available to the fishery?
- Kudu Scenario Kudu are an antelope species found in easterm and southerm Africa. Male kuou have dramatically spiraled homs, which makes them a target of trophy hunters. Begin by setting up the following parameters: k= 100, r= 0.26, N, = 10. Use the gear icon to adjust the min & max values of N, and k to 2 and 200, respectively. Set the max value oft to 50. 25. At what time ("T value) do kudu populations reach their carrying capacity, given these parameters? 28. What happens to the growth rate of a kudu population as it gets closer and closer to its carrying сарacity? 27. What sorts of environmental changes might cause k to increase in this environment? What might cause k to decrease? 28. Trophy hunters move into the area, leading to an increased death rate, which decreases the growth rate rto 0.13. Exolain how this change will impact the population growth patten. [Hint Look at when the population now reaches its carrying capacity, given this decrease in r. Compare your original curve…The following equation is used to calculate the population growth rate, Ro, per generation from a life table. Iy is survival probability from birth to age x and my is fecundity at age x. Ro = Elkm Multiplying ly and my and summing it over all age categories in the life table gives the population growth rate per generation because: Calculating the reproductive output for each age class requires considering the survival probability to that age (a dead individual does not reproduce) and the fecundity at that age by multiplying them with each other. Summing over reproductive output for all age classes gives the total per capita growth rate of the population The fecundity at each age is lower when the survival is higher because of energy constraints. Multiplying probability of survival and fecundity in each age class takes this trade-off into account. Summing over reproductive output for all age classes gives the total per capita growth rate of the population The resulting type of growth…1.
