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.

biologists were able to estimate that, on average, only 5 fisher kits (young animals) survived to 1-year of age each year. DEC wants to change this harvest quota to maintain a stable fisher population for the next 10-years. How much would they have to change the harvest in every year to achieve this goal?

ESTIMATING POPULATION SIZE USING THE LINCOLN INDEX 1. A biologist wants to estimate the size of a population of turtles on an island. He captures 20 turtles on his first visit, and marks their backs with red paint. Two weeks later he returns to the island and captures 25 turtles. Five of these 25 turtles have red paint on their backs. Using the Lincoln index equation, calculate the estimated population 2. Overfishing in Antarctica has resulted in a steep decline in Patagonian toothfish. Fishery scientists are monitoring the population size to see if it is recovering by using the mark-release-recapture method and the Lincoln index equation. On their initial visit, the scientists caught and marked 100 specimens. When they returned on a second visit, they captured a total of 70 Patagonian toothfish. If the scientists estimated the population size was 700, how many of the recaptured toothfish were marked? Show all working.
There are two types of life strategies used by organisms to survive in their environment. 1. K-selected strategy - growth rate is near the carrying capacity 2. r-selected strategy - growth rate is near biotic potential Match the characteristices below to the life strategy they represent J-cruve Logistic Growth Long life span Few offspring
Using the logistic equation, calculate population growth when K =1,000, N = 100, and r = 0.1. Compare the result with that shown inSection 56.3, where K = 1,000, N = 900, and r = 0.1, and with theresult when K = 1,000, N = 500, and r = 0.1.
Categorize the following density-independent factors by their cause and effect. The four categories are natural/catastrophic, natural/gradual, human-made/catastrophic, and human-made/gradual. A volcanic explosion results in lava flow over five square miles where a population of rare orchids lives. A vernal pool driesup a few weeks earlier than normal, impacting a population of spotted salamanders that used the pool to breed earlier in the season. A toxic chemical spill directly into a lake kills eggs, small fry, and all females in a dense population of bass. An increase in demand by humans increases harvesting of shrimp by people in the fishing industry.
