Summary Introduction
Introduction:
The genetic drift can be defined as the variation in the relative frequencies of the alleles. This generally occurs in the small population, which may result in the disappearance of the alleles. The founder effect is a type of genetic drift resulting due to the separation of a small population from a large population.

Draw a graph with a growth curve for a population that starts at 10 individuals and experiences exponential growth. Draw a second graph with a growth curve for a population that starts with 10 individuals and undergoes logistic growth. The second graph should have a carrying capacity of 100 individuals. Please give a proper written explanation for the graphs.
Distinguish between the exponential and logistic growth of a population and describe the nature of their growth curves. Define environmental resistance. What is the carrying capacity of an environment? Define and give an example of a population crash.
The global human population has surpassed 7 billion, far exceeding our population’s size throughout our history on Earth. Name some specific means by which we have apparently raised Earth’s carrying capacity for our species. Do you think we can continue to raise our carrying capacity? How might we do so? What limiting factors exist for the human population today? Might Earth’s future carrying capacity for us decrease? Why or why not?

What part of the logistic growth equation produces the sigmoidal growth curve?arrow_forwardA 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 Karrow_forwardWhat are the challenges posed by population growth?

- According to Worldometers, in late November, 2018, the U.S. population was 327,726,061 and the world population was estimated at 7,666,602,725. Considering those numbers, do you think the United States is in a population crisis? Do we have enough land and resources to support a continuous increase in population? Should we, as a nation, concentrate on controlling our population or controlling resource use? Why, or why not?arrow_forwardA population of Giant armadillo, an endangered species found in South America, increased in numbers from 152 to 174 from 2001 to 2006.

- 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?arrow_forwardLet us assume that an insect population in its first year has 5 individuals, in its second year has 10 individuals, and in its 3 (and current) year has 20 individuals. Assuming they mate continuously, what will the size of the population be next year (year 4) given that the population growth has a 2-year time delay and a growth rate of 1.2? Assume that the carrying capacity is 200. O 41 O 23 05 O 20 O 43 O 53 O21 O 10arrow_forwardIn 2010, 150 coyotes (Canis latrans) were counted in Pierce County, WA. And the growth rate is 14 coyortes per year. Following a survey of the community, the social carrying capacity of coyotes was around 500 individuals. How long will it take for the coyote population to reach this human tolerance goal? Biologists have estimated the biological carrying capacity for coyotes in the county to be 1000 individuals. How long will it be before the population reaches carrying capacity using exponential growth? Would it take more or less time for the population to reach carrying capacity if using logistic growth equation and assumptions?arrow_forward
