Ecology contains two words: Eikos means dwelling, and logy means to study, so the combined meaning is studying habitat or living.

Question

In the logistic growth equation the highest instantaneous population growth rate
(dN/dt) is reached
When the population is smallest, because then intraspecific competion and thereby resource limitation
is weakest
When the population is near K, because the largest population still growing has the highest growth rate,
as it has the highest number of reproducing adults
When the population is in the middle between zero and K (N = K/2) because then the trade-off between
still having modest negative effects of intraspecific competition on growth rate but having a relatively
high population size of individuals that could be reproducing is optimal

Using the logistic equation, calculate population growth when K =1,000, N = 100, and r = 0.1. Compare the result with that shown inSection 56.3, where K = 1,000, N = 900, and r = 0.1, and with theresult when K = 1,000, N = 500, and r = 0.1.
A few plant-eating salamanders manage to float on a log to a large island in the Pacific that did not have any other salamander species previously. The salamanders find the island has abundant plants for food and no predators. On average, a salamander has four offspring per year and lives for one year. Refer to the equation for the logistic growth model if you were modeling salamnder population growth with this logistic growth equation, during the first few years, a) N<K b) N=K c) N>K d) there is no relationship between N and K

Which of the following statements about logistic growth is not correct? A population growing logistically has reached the carrying capacity of the environment in which it lives. A logistically growing population is represented by an S-shaped curve. When a population is growing logistically, it is limited by factors such as food supply and water. In a logistically growing population, the birth rate is much greater than the death rate.
Which of the following are true for a population that is increasing according to the exponential growth equation?

The discrete logistic function (the one you can solve with your calculator) has a time lag built in = one generation. What would a greater time lag do to the outcome? increase the chances of population exceeding K decrease the chances of population exceeding K slow down population growth by decreasing r increase population growth by increasing r it would have little/no effect under all circumstances
