Homework SourseA team is studying a local migratory bird species in a habit
A team is studying a local migratory bird species in a habitat conservation area and have recorded the following lambda values: Year 1, lambda = 1.3 Year 5, lambda = 1.3 Year 10, lambda = .95 Year 15, lambda = .8 Year 20, lambda = .75 Which of the following statements about this population is FALSE?
| A. This population is beginning to recover due to the establishment of the habitat conservation area. |
| B. This population began experiencing smaller population sizes every year, starting in year 10. |
| C. This population is experiencing an increase in death rates, a decrease in birth rates or both. |
| D. This population is declining and may go extinct. |
| E. This population is likely experiencing habitat loss somewhere on its migratory route. |
Solution
Option A is false
As it is clear from the lanmbda values given, the population was growing the first and fifth year has been steadly decreasing from 10 years and has shown a steady decrase of 0.8 between year 5 and year 10 and a steady decrease of 0.5 every 5 years since and the reasons for that could be any of the other options B, C, D, and E
