- A mess of 40 iguanas moved to a new island which is so large that the carrying capacity is essentially non-existent. The growth rate for these island iguanas was 0.6 and they have a generation time of 2 years. How many iguanas do you expect to find on the island after 6 years? (Show your work. Round your final answer to the nearest whole iguana and clearly indicate your final answer).A population of 100 kit foxes colonizes a new grassland with no other foxes in it. The grassland has a carrying capacity for foxes of 200, and the fox population has a maximum growth rate of 60% per year. What will the population of kit foxes be ** 2 years from now (rounded to the nearest whole fox). *note that the current time frame is year 0. You will have to calculate years 1, and 2. 128 157 145 168A particular specie of animal has a carrying capacity of K and a growth rate of r. From an initial population of N0, what will be its population after a very long time? Show your calculations.
- Assume a population of desert tortoises has a per capita growth rate (r) or 0.039. If this rate could be sustained, how long would it take for the population that is currently 186 individuals to reach 450 individuals? (just give the simplest expression with the data provided). Edit View Insert Format Tools Table 12pt Paragraph BIU AT²There 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 offspringIn 1929, 13 white-tailed deer were introduced to an isolated island with no natural predators. A survey was conducted once a year to estimate the population of deer on the island. The table shows the deer population over the first five years on the island. The deer fed on many of the native plants found on the island, including the California false indigo, a thornless shrub that is a preferred food source on the island for deer. Based on the data, which of the following graphs correctly predicts the population of California false indigo from 1929 to 1941? Year of Survey Population of Deer 1929 13 1932 29 1935 66 1938 157 1941 398 image 1 because the California false indigo will be able to reproduce faster than it can be consumed by the deer and will be unaffected by the deer population, maintaining its current population image 2 because the increasing number of deer will help spread seeds of the plant and lead to a rise in…

One pair of cats can produce 12 kittens in one year, and half of these kittens are female; this increased population would potentially produce 84 kittens in the second year. In 5-years, the population could reach almost 33000 feral cats. A) What conditions or factors would have to be in place for the population to achieve its biotic potential?
- You study a population of snails recently introduced to a small lake 10 years ago. You know that 7 snails were originally let go in the lake by a cottager. The lake has no snail predators nor any other species occupying the same or a similar ecological niche. You know from your research that, under ideal conditions, the instantaneous rate of increase of this snail species is 0.5. You also think the conditions on the lake were ideal when the snails were introduced. After surveying the food available in the lake, you estimated that there is enough food to support a population of 1696 snails. How many snails do expect to be in the lake now?A population of boreal toads has a current size of 100 and time steps are measured in years. If the instantaneous rate of increase is 0.8 (toads/(toadXtime)), what will the expected population size be after two years? Note: You need to first figure out which equation to use for this problem. O 64 toads O 117 toads O 495 toads O 6400 toads No toads will be left because the instantaneous rate of increase is less than 1.0.Part A: A population of 100 Asian elephants exhibits logistic growth. If the carrying capacity is 500 elephants and theper capita growth rate is 0.1 individuals/(individuals × year), what is the maximum population growth rate forthe population? part b: Based on the above question, what is the maximum population growth rate for the population if we assumedthe elephants were undergoing exponential growth?
