Question

6. You are interested in a population of mockingbirds on an island. You measured the population size for two years: Population size at time 0 = 75 birds, Population size after 1 year = 100 birds, Population size after two years = 145 birds. What is lambda between year 0 and year 1?

Answer 1

Answer:

1.3333...

Step-by-step explanation:

We need to know that

$\lambda = \frac{N_{t+1}}{N_t}$

Where $N_t = Population \ at \ the \ initial \ year\\N_{t+1} = Population \ one \ year \ after$

Using the data of the problem

$\lambda = \frac{100}{75} = 1.333...$

so lambda is 1.333...
