- A severe winterkill seemingly killed all the trout in a lake. A decision is made to restock the lake with trout from a nearby lake. The carrying capacity of the stocked lake is estimated at 11,500 trouts and the instantaneous rate of increase of the species is estimated at 0.006. If the lake is stocked with 800 trout, how many trout will be in the lake after 55 years. Round your answer to the closet full number.Example: Lynx and Hare: 1. What occurs to the Lynx population when the number of snow hares increase? KEY Snowshoe hare Lynx 160 2. Why does the number of lynx decreases in year 1925? 120 80 40 3. Between what two years is the hare population at its greatest? 1850 1875 1900 1925 Year Carry Capacity: Thousands of lynx1.

- Let 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 10What if we were able to restore some critical salmon habitat, like the forests surrounding the spawning streams? To test this restoration, increase K to 40,000 fish. What would that do to the MSY value? [ Select ] Does this mean you would be able to harvest more or less fish? [ Select ]Suppose that researchers wanted to examine the combined effects of an introduced predator (a trout) and the trematode parasite Ribeiroia on amphibian populations. To do this, they established frog populations in each of 40 artificial ponds. Each pond was assigned at random to one of four treatments (10 ponds per treatment): 1) neither trout or parasites were added to the pond (the "No trout, no parasite" treatment); 2) no trout were added but parasites were added ("No trout, parasite added"); 3) trout were added but parasites were not added ("Trout added, no parasite"); and 4) both trout and parasites were added ("Trout added, parasite added"). Each pond contained refugia where tadpoles could avoid attack by trout, to avoid fish predators driving frog populations to extinction in an artificial pond, unlike what typically occurs in a natural pond. After two breeding seasons, the researchers estimated the density of frogs in each pond. The results are shown in the table and the figure.…
- The following questions are based on the situations below. Situation 1: A population of trout in a lake has significantly declined over the past year. The main source of food for the fish in this lake are aquatic insects. Due to poor climate conditions, there are significantly fewer insects and thus, not enough food to sustain the population of trout in the lake. Trout is a food supply for larger fish in the lake and without enough trout, other fish are negatively impacted in the lake. 14. What is the problem? a. Trout population has increased b. Insect population has increased c. Insect population has decreased d. Larger fish population has increased 15. What has caused the problem? a. Poor climate conditions b. Humans overfishing C. Pesticides being used on the insects- d. Decreased water levels 16. How could humans alter carrying capacity so the trout population returns to its normal level? a. Humans could alter the carrying capacity by hunting the trout b. Humans could alter the…Carrying capacity is and is represented by the letter on the graph. O the maximum number of individuals Lhat can fit into an area: A the greatest number of individuals that arn area can suslain over the long tem: C the decline of a population due to limiting factors B the smallest number of individuals thal Can live in an area: Cafter the bamboo fruiting: In reality, this high carrying capacity cannot be sustained for longer than a few weeks.When the bamboo fruits and rice run out, the carrying capacity reverts to the levelobserved before the bamboo began to fruit.
