Solved in 2 steps
- 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.What is often true of a population of organisms with a type Il suvivorship curve? they produce few offspirng and invest more energy in each offspring they produce more offspring and invest little energy in each they have low death rates during early life stages they are equally likely to die at any ageWhat if we were able to restore some critical salmon habitat, like the forests surrounding the spawning streams? To test this restoration, increase K to 40,000 fish. What would that do to the MSY value? [ Select ] Does this mean you would be able to harvest more or less fish? [ Select ]

Show how the graphs would change of the prey follow a logistic growth model.
- A fishprint provides a measure of a country’s fish harvestin terms of area. The unit of area used in fishprint analysisis the global hectare (gha), a unit weighted to reflect therelative ecological productivity of the area fished. Whencompared with the fishing area’s sustainable biocapacity (itsability to provide a stable supply of fish year after year,expressed in terms of yield per area), its fishprint indicateswhether the country’s annual fishing harvest is sustainable. The fishprint and biocapacity are calculated using thefollowing formulas:Fishprint in (gha) = metric tons of fish harvestedper year/productivity in metric tons per hectare ×weighting factorBiocapacity in (gha) = sustained yield of fish in metrictons per year/productivity in metric tons per hectare ×weighting factorThe following graph shows the earth’s total fishprint andbiocapacity between 1950 and 2000. Study it and answerthe following questions: If biologists determine that this country’s sustainedyield of fish is…The logistic model incorporates carrying capacity to make the model exponentialA 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.
