Question

Your accounting table contains a column for the number of individuals in the next generation (Nt+1). Fill in N+1 by looking ahead one time step to see how many individuals will be present up to T8. Then divide Nt+1 by Nt and place this new number (Nt+1/Nt) into the appropriate column in your table. Nt+1/Nt is called the finite rate of increase because it caleulate the number of new individuals produced per existing individual during tha period. You have just calculated the finite rate of increase for several one-day time inte However, the time interval can be any unit (i.e., one day, one week, one year, three yea The finite rate of increase can be useful in estimating the population growth rate witho nowing birth or death rates. You may find this ideal for the lab. a) Below is the calculated finite rate of increase over an 8-day time interval from TO to T8: N8/NO-149/1-149 b) Using your worksheet data, calculate the finite rate of increase for two 3-day time intervals, from TO to T3 and T3 to T6. TO-T3 7 T3-T6 6.29 Q10b Notice the finite rate of increase varies depending on what time period you are measuring. Can you think of a reason why? Your answer

Explanation / Answer

The finite rate of increase (lambda) varies depending on the time period because when a population increases the members are involved in intraspecific competition for resources such as food, mate and shelter. The act as the limiting factor on finite increase of population. So, the finite rate of increase is decreasing depending on time period.
