- 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.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 ]A colony of aliens reaches planet Earth in 3000 BC and set up a base in Antarctica. If their initial population is 100 and their specific growth rate is 0.02263/year and their yieid coefficient is 0.85, then in what year (AD) will they start to outcompete humans for resources negiecting resource and logistic growth limiting effects? Assume the human population 3000 BC is 50 million, the human yield coefficient is 0.75 and the human specific growth rate is 0.02/year. Answer:
- Flowering rush (Butomus umbellatus) is a pink flowering perennial that has been identified as a prohibited noxious weed in Alberta. It is native to Europe, Africa, and Asia, but due to its prolific growth rate on shorelines, it has been crowding out the native species of Alberta.

These species are known to compete for some but not all of their resources. We are able to determine that the carrying capacity of the bison K1 is 200 and that the alpha (competition coefficient) is 4. The carrying capacity for Elk (K2) is 100 and the beta (competition coefficient) is 1.Label this logistic growth curve:
- If a salmon population has a geometric growth rate of A (lambda) = 0.5 it is Increasing in abundance not changing in abundance decreasing in abundance impossible to tell with the given informationDid the normal growth curve grow at a slower or faster pace than in the new growth curve? Did they level out or reach the same carrying capacity? (The normal growth curve is the light blue line and the dark blue is the new growth curve)Back at the original beaver population, only 40 beavers remained. This population also has a growth rate of 0.6 and generation time of 2 years. But the place on which this population resides is much smaller and has a carrying capacity of 200. How many beavers do you expect to find in the original population after 6 years?
