Summary Introduction
To determine: The population of female butterfly after five year.
Introduction: The finite rate of increase in a population is the ratio of size of population from one year to the next year. It is represented as λ. Some ecologists use finite rate of increase instead of net productive rate to predict the population growth.

A population of rabbits contained 200 individuals in 2017 and 300 in 2018. What was its finite rate of increase, λ, over that one year?
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.
