Pre-Lecture Lesson 1.6: Energetic limits to population growth

Under what conditions does a population experience exponential population growth?

when r is constant and positive

What happens to population growth when r is negative?

Population declines

How will our mouse population behave if it is given a constant amount of food every month?

reach a stable population size

What is the value of $r$ at which population growth has stabilized and population size has become constant from one generation to the next?

r = 0

What happens to the term (K-N)/K when N (the number of individuals in the population) exceeds K? And, hence, what happens as a consequence to the change in population size from this generation to the next?

Change in population size is negative; it will decline

Which of these 2 strategies is more likely to overshoot the carrying capacity and cause boom and bust cycles, and which is able to maintain a more steady population size around the carrying capacity?

r-strategists are more likely to overshoot K; K-strategists are more likely to maintain N around K
