Which set of values for the intrinsic rate of increase, finite rate of increase, and net
reproductive rate could describe the same growing population?
(Note: you should not need to do any math to figure this one out. Just think through general
interpretations of each parameter)
Or = -0.14, A = 0.87, RO = 0.5
r = 3.0, A = 0.22, RO = 0.5
r = 0.22, A = 1.25, RO = 3.0
%3!
r =
= 0.22, A = -0.14, RO = 0.5
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…

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.arrow_forwardFor each organism, create a survivorship curve by plotting the given information in a line graph. Title each graph "Survivorship Curve for [name of organism]." The y-axis should be labeled "Survivorship" and contain low, medium, and high indicators. The x-axis should be labeled "Life Span" and contain young, middle-aged, and old indicators. American toads practice explosive reproduction. During the first warm days in spring, both males and females migrate from forests and converge on ponds. Reproduction is quick, taking only a few days. Females lay hundreds of eggs in jelly-filled sacks along the sides of the pond or stream. As soon as the eggs are laid, males and females abruptly leave the pond. Even before they hatch, the offspring are prone to high rates of predation. Many offspring die before they reach adulthood. Of the offspring that do survive, some will die in adulthood, and some will live their entire natural life span.arrow_forward
