Question

How long will it take a population of 550 moose to double if 25 offspring are born and 14 moose die on average per year? 79.0 years 52.3 years 34.5 years 26.9 years 3. The equations used in the tut0rial apply to populations over short time intervals. Why can they not be applied to populations over very long time periods? Real populations are affected by resource limitations that are not accounted for in the equations. The equations only apply to small populations and so populations become disqualified over long time periods as they get larger. Large values for time cannot be used in the equations without generating error. The equations are meant for theoretical applications only and cannot be used in the study of real populations. What is meant by the term “doubling time” and how did changing values for N0 affect the doubling time of a population? Doubling time is the amount of time needed for a population to double in size; increasing N0 increased the doubling time. Doubling time is the amount of time needed for a population to double in size; increasing N0 did not change the doubling time. Doubling time is the time needed for an individual in the population to reproduce itself; increasing N0 decreased the doubling time. Doubling time is the time needed for an individual in the population to reproduce itself; increasing N0 did not change the doubling time.

Explanation / Answer

Ans 1 c 34.5 yrs

Doubling time = 70 / growth rate

Growth rate = [ ( 25 -14) / 550 ] × 100

= 2 %

Doubling time = 70 / 2

= 35 years
