My Question is By Using Excel program
Table summarizing vital rate data on cougars. The survival estimates are annual rates. The sex ratio at birth is 1:1 and the proportion of females producing young in any year was 0.55 (0.45 females have dependent young and do not reproduce ).

a- Construct a deterministic stage structured model and model both males and females. You can use a matrix approach or write the equations directly ; however , make sure you label your parameters , table entries and column headings clearly. Simulate the population for 30 years .
B- Begin with population vector of 5 kittens and 5 juveniles and 5 adults . What is the stable age distribution for each sex and Lambda for this population ?
C- is the population declining , stable , increasing ( Please show graphically)
D- Given the modeling results
Does it make sense to allow harvest of this population ?
What age ,sex, or combination would you allow to be harvested?
What parameters would you change to model the harvest?
