1) Lemma minor, a species of duckweed, can reproduce to form new plants very quickly.
1) Lemma minor, a species of duckweed, can reproduce to form new plants very quickly. Suppose that a small backyard pond contains 25 Lemma minor plants, and the expected growth rate of the population is 1.0 X 102 plants per day. How many Lemma minor plants the pond will contain after 31 days.
2) According to population surveys of piping plover, there were 34 of these birds on Dowling Lake, Alberta in 1992. The next year, the population of piping plover on Dowling Lake was 39. Calculate the per capita growth rate for the piping plover population during the entire survey period.
3) Between 1996 and 2001, Cochrane, Alberta, was the fastest growing municipality in Canada with a per capita growth rate of 0.589. There were about 7424 people living in Cochrane in 1996. How many people lived there in 2001?
4) The experimentally re-introduced grey wolf population of Idaho was 310 at the beginning of 2004. During the year, 112 pups were born and 49 individuals died or were removed from the study area. Calculate the per capita growth rate of this grey wolf population during the study period
5) Six one-drop samples in a Paramecium sp. population had the following numbers of organisms: 4, 6, 5, 3, 6, and 6. If 20 drops represent 1 mL of solution, and the volume of the solution is 40 mL, calculate the size of the population.
6) A population of rattlesnakes contains 1000 individuals. During the year, there are 106 births, 53 deaths, 42 immigrations, and 15 emigrations. Calculate the per capita growth rate for the year.
