40 beavers moved to a new place which is so large that the carrying capacity is essentially non- existent. The growth rate for these beavers was 0.6 and they have a generation time of 2 years. How many beavers do you expect to find in that place after 6 years?

Pronghorns look very similar to antelopes and are considered the fastest mammal in North America. They can be found in the Southeastern parts of Alberta.     In the 1800s, it is thought that the population of pronghorns reach 35 million in the Prairies. By 1924, only 20,000 pronghorns could be found in Alberta. In 1996, only 9,600 remained.    What is the per capita growth rate of pronghorns in Alberta between 1924 and 1996?    Express your answer as a value between 0 and 1 rounded to two decimal places. If the population is decreasing indicate this with a negative sign.  Answer

Graph 2: Average Toe Length a. In 1800, about how many people surveyed had a 3 cm toe? How many in 2000? b. The data shows the c. In 2000, what is the average toe length? Number of people (in thousands) 120 100 80 60 40 20 growth curve. Year 2000 Year 1800 Name: Graph 3: Mexico and US selection has occurred? Length of big toe (in centimeters) May 1st What is the average toe length in 1800 a. In Mexico, what percentage of the population is between 0-4 years of age? In the US? b. Which population is growing the fastest? c. Which age group has the smallest number in both countries? Chart 4: Trapping Geese In order to estimate the population of geese in Northern Wisconsin, ecologists marked 10 geese and then released them back into the population. Over a 6 year period, geese were trapped and their numbers…

False Question 51 For the organism that live there, only the size of a habitat matters, not it's shape. True False Question 52 we move in longitudinal gradient corr

A forest restoration project monitors the growth of tree saplings in a controlled area. The carrying capacity of this area is 500 saplings, and the initial number of saplings is 50. With a growth rate of 0.82 per month, what will be the number of saplings the following month? O 113 87 91 163

7) The following data has been obtained from the coastal haddock (Melanogrammus aeglefinus) fishery of Maine. The fishing season was divided into 10 periods. Period Catch per Period 1 208 2 195 3 168 4 132 5 91 6 80 7 63 8 56 9 48 10 33 It was also recorded that five fishing trawlers were in operation during each period of the fishing season. Question: What was the size of the haddock population originally available to the fishery?

At what general size does a fish population have the greatest potential for growth and reproduction?

It is projected that we will lose what percentage of the present species richness by middle of the century

Draw on one graph, with N2 on the y-axis and N1 on the x-axis, the isoclines for the twocompetitors with the carrying capacities and competition coefficients listed below. Will thesespecies coexist? If not, which species will win? Competitor 1                                           Competitor 2 K1 = 200, α12 = 0.4                                 K2 = 400, α21 =1
