Question

Survivorship can be used in conjunction with other demographical information to calculate whether a population is growing or shrinking over time. Please examine the following table and Use the data and equation given to you to fill in all of the blank spots in the table. Is this population growing or shrinking over 1 generation? How can you tell? What is the difference between r, the instantaneous growth rate, and R_0, the generational growth rate? What range of values for r indicate that a population is growing, shrinking, or staying the same? Part2 Continuous and Discrete Exponential Growth Exponential growth models are the simplest way in which to conceptualize populations growing in an environment with unlimited resources over times. For populations that grow continuously throughout the year, we use the instantaneous rate of growth (r). However, some populations have specific periods of time in which births occur, and for these populations, we use lambda (lambda) to describe the discrete growth rate. Please use the following equations to solve the following problems pertaining to exponential growth. N(t) = N_ce^rt dN/dt = rN lambda = e^r N(t) = N_e lambda^' ln (x') = y ln (x) In c = 1 A population of mice continuously breed over the year. A small population colonizes an island with plenty of food and no predators and their population begins to grow exponentially, if the original population size colonizing the island is made up of 40 individuals, and the intrinsic growth rate is 0.3, how many mice will be on the island in 4 years?

Explanation / Answer

so, in the above first table first find/ fill the survivorship column

N(X)/N(o)= 0,1,2,3,4,5,6,7,8 and l(x)*m(X)=0,0,1,2,0

2. Population is shrinking as shown by the last 7 year , the zero stats.

3. The difference is instantaneous growth rate is population rise in that particular period/point of time and generational growth rate is population inc/dec in a generation/s

and here the generational growth rate is (R0)=, G is also calculated as it is the overlapping generations incorporated into growth from population.

ie

so, the r will be G = 2.57, R0= 1.4, ln(R0) = .336 and r=.131

Here r=.131 is showing that population is shrinking
