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.

- When does the growth rate of a population following the logistic model equal zero?the logistic model is given as dN/dt = rN (1-N/K)What does the logistic growth equation describe? Multiple Choice A population that crashes after very rapid, nearly exponential growth. A population that is increasing in size, but never reaches its carrying capacity. A population that is declining in size and with further time may become extinct. A population that grows steadily the population is small and more as it approaches the carrying capacity.ASAP
- 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 circumstancesWrite a generalized model for exponential population growth. Define your terms. Then, draw a plot showing an example, being sure to label your axes. Write a formula that extends the preceding model to incorporate carrying capacity, producing sigmoidal population growth. Define your terms. Then, draw a plot showing an example, being sure to label your axes.If a population has a constant r = 0.3 Group of answer choices the per capita rate of population increase continues to accelerate as the population grows the time necessary for population size to double gets shorter as time goes by since population size is increasing exponentially the absolute increase (change in population size per unit time) is also constant the time necessary for population size to double is also constant

- A population of bats exhibits logistic growth. The carrying capacity is 600 bats and the maximum per capita Growth rate (rmax) is 0.20. The population size was determined periodically. Determine the population growth rates based on a population size of 50, 100, 200, 350, 480, 500, 525, and 600 bats. Include up to three decimal places in your answers.

Describe the relationship between population size and growth rate. üüThe 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?Population size (M) K NX K The figure depicts which type of population growth? logistic normal geometric Time (t) exponential
