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.

Question

Define exponential growth and logistic growth.

Definition Definition Point at which the growth rate of a population decreases as the number of individuals increases. Factors such as inter- and intra-species competition and disease cause population growth to level off.

The maximum sustainable yield (MSY) is the highest rate at which a potentially renewable resource can be used indefinitely without reducing its available supply. The idea is to remove individuals while keeping the population at a constant growth rate and size, but to find the size where the harvest is maximized. The greater the growth rate, the more individuals you can remove and not change the population size. Where is the growth rate at its maximum? To find this look at your logistic model simulator. 1. Set up a hypothetical salmon population where the carrying capacity is 20,000 fish, the maximumr is 0.7. According the the maximum sustainable yield (MSY), at what population size should we maintain the salmon while fishing?
