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.

Unless actions are taken to slow the decline of domesticated honeybees and augment [increase] their populations with wild bees, many fruits and vegetables may disappear from the food supply, said Claire Kremen, a conservation biologist at Princeton University in New Jersey.. The honeybee decline, which is affecting domesticated and wild bee populations around the world, is mostly the result of diseases spread as a result of mites and other parasites as well as the spraying of crops with pesticides, scientists say. Source: "Bee Declines May Spell End of Some Fruits, Vegetables," National Geographic News, October 5, 2005 14. The decrease in the honeybee population is partly due to A. the use of pesticides B. the use of fertilizers C. a decrease in prey D. a decrease in fruits and vegetables 15.

- 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.Deer Population on an Island 120 100 96 80 78 60 6아 40 36 20 TO 1 2 3 4 5 6 7 8 9 10 11 12 Number of Months Dear population 1-During which months was the growth of the deer population exponential? | 2-Give one possible reason why the population decreased after 5 months 3-What is the approximate carrying capacity of the island? 4-Explain "carrying capacity" 5-What type of density independent factors may cause the population to decrease (name 2)? 6-What type of density dependent factors may cause the population to decrease (name 2)? 7-Overall, do deer populations seem to exhibit exponential or logistic growth?
