Mr. Bait, the owner of the fishing resort on the lake, wants to increase the number of troutavailable for his clients to catch fishing. He plans to stock the lake with 2,000 more trout. Explain to Mr.Bait what will happen to the lake and the salmon population if he adds 2,000 extra fish. Use a diagramor graph to defend your reasoning.

Adding 2,000 extra trout to Lake Maria will likely have several effects on the lake and the trout…

What 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 ]
Describe the methods that are being used to restore salmon populations and what specific requirements of the salmon life cycle these help with. Focus on their freshwater habitat.
3. A population of 1,492 Baltimore Orioles is introduced to an area of Nerstrand woods. Over the next year, the Orioles show a death rate of 0.395 while the population drops to 1,134. What's the birth rate for this population? Is this proving to be a suitable habitat? 4.780 turkeys live in Merriam township, which is 92 acres in size. The birth rate is 0.472 turkeys/ year. The death rate is 0.331 turkeys/ year. What is the population density? а. b. What is dN/dt? с. Predict N after one year, assuming dN/dt stays constant. One dandelion plant can produce many seeds, leading to a high growth rate for dandelion populations. If a population of dandelions is currently 40 individuals, and rma= 80 dandelions/month, predict dN/dt if these dandelions would grow exponentially. 5. Imagine the dandelions mentioned in #5 cannot grow exponentially, due to lack of space. The carrying capacity for their patch of lawn is 70 dandelions. What is their dN/dt in this logistic growth situation? 6.

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…
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.…
1. As with any growing city, construction in the Jacksonville area can mean that ecosystem areas needed for native animals and plants continue to shrink in size. For example, tortoises that burrow underground must be relocated to survive, as the weight of construction machinery and of new buildings will destroy the tunnels in which they find shelter. Complete the following statements about the aftermath of construction if no action is taken to save these animals. As the human population increases, __________. A. the tortoise birth rate will increase.B. the tortoise birth rate will remain constant. C. the tortoise death rate will increase.D. the tortoise death rate will remain constant.
