Constant mortality 50 rate with age and increasing reproduct

Constant mortality (50%) rate with age and increasing reproductive output with age Calculate Ro for the two scenarios above and use those values indicate whether the earth back Turtles can be saved and if so. whether through increasing survival of hatchling turtles or increasing survival of adults

Solution

First, we can calculate net reproductive rate by using following formula:

Net reproductive rate Ro = l_xm_x

For first group [Increaswe survival of hatchlings]

First calculate l_xm_x for each column
