Question

For the 5 daphnia treatment the net reproductive value (Ro) is _____________ individuals.

5 Daphnia/tube
Age(days)	nx	bx
0	5.000	0.000
1	4.321	0.598
2	3.180	0.641
3	3.266	0.352
4	3.102	0.385
5	3.053	0.292
6	2.302	0.261
7	1.912	0.214
8	1.711	0.182
9	1.313	0.370
10	1.348	0.275
11	1.163	0.127
12	0.943	0.190
13	0.961	0.459
14	0.949	1.074
15	0.883	0.648

Answer 1

Net reproduction rate Ro

R₀ = E lx*bx

Age(days)	nx	bx	lx= nx/no
0	5	0	1	0
1	4.321	0.598	0.8642	0.516
2	3.18	0.641	0.636	0.407
3	3.266	0.352	0.6532	0.23
4	3.102	0.385	0.6204	0.238
5	3.053	0.292	0.6106	0.179
6	2.302	0.261	0.4604	0.12
7	1.912	0.214	0.3824	0.081
8	1.711	0.182	0.3422	0.062
9	1.313	0.37	0.2626	0.097
10	1.348	0.275	0.2696	0.074
11	1.163	0.127	0.2326	0.029
12	0.943	0.19	0.1886	0.035
13	0.961	0.459	0.1922	0.088
14	0.949	1.074	0.1898	0.203
15	0.883	0.648	0.1766	0.1144
				Ro = 2.4734

Ro is 2.4737 per one daphnia
