Question

As a wildlife biometrician for CPW, you are asked to take the lead on assessing the status of a recently introduced group of Argali sheep. Data were collected on a specific cohort of offspring from the introduced population numbering 750 females. The number of individuals surviving was recorded as well as the number of births produced (assume a sex ratio of 1:1).

Age	Number females surviving	Number of female births
0	750	0
1	320	0
2	310	134
3	295	208
4	272	212
5	240	202
6	221	166
7	192	86
8	170	45
9	90	12
10	10	0

From this information, you are requested to produce the following for a presentation on the success/failure of the program:

(1) A life table showing survivorship (l_x) and mortality (q_x). (2 points)

(2) One figure showing both survivorship and mortality curves using excel (x-axis will show age) (2 points).

(3) Calculate and present R_o, G, r, and λ (show your work-4 points). State what each means and how R_o and G differ and how r and λ differ (2 points).
