Population Growth
R and K Selection
R and K selection are concepts in ecology used to describe traits in the fluctuation of a population or population dynamics. For example, they describe the life-association traits between parent and offspring, such as quantity or number of young ones born at a time, quality of parental care, the age to maturity, and reproductive effort.

Study the 3 diagrams showing hypothetical moose populations with 2 different dispersion pattern.Describe how the moose are dispersed in each diagram2. The shaded portions of the diagrams show the transects that were used to sample each population.What proportion of the total study area (defined by the box) was sampled in each of the three cases?3. Count the number of moose encountered within the transect areas for each case. Do not count the total number of moose in any of the diagrams. From these counts, estimate the size of the 3 moose populations. 4. The actual numbers of moose in the 3 populations are 60, 133 & 133, respectively. How close were your estimates? What do you think affected the accuracy of the estimates in each case?5. How would you design a sampling experiment on a wild population? Note that in real life, the time & expense involved usually restricts the proportion sampled to between 10-20% of the total area of interest.

- 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 1.0.2. As a fish farm manager, you need to prepare a pond of size 1.0 Ha for stocking 5.0 g Nile tilapia fingerlings. a. Describe the steps you will take to successfully do the stocking b. Calculate the total number of fingerlings that will be stocked if the stocking rate is 10 fish/m2. c. Suggest with reasons the type, pellet size and quantity of feed you would give to the stocked fish/day in the first week of stocking.For the cricket, the intrinsic growth rate is 100 and the carrying capacity of the environment is 200,000 individuals. For the frog, the capture efficiency is 0.0002, the conversion efficiency is 0.1, the handling time per cricket is 0.2 hours, and the density-independent per capita death rate of the predator is 0.4. 18. At what value of the number of crickets is the predator population of frogs at equilibrium? 19. What is the dN/dt of the prey population when the number of frogs is 60 and the number of crickets is 11,000? Round to the nearest hundredth. 20.
