# it is about stage structured model

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 ).

stage name

0.00

 Kittens Female Female survival rate Male survival rate Kitten 0.00 0.72 0.53 Juvenile 0.76 0.50 Adult 2.00 0.87 0.65

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?
