A   single   breeding   pair   of   rabbits   is   introduced   to   Australia   in   1900.   Assume   (for   
simplicity)   that   each   pair   can   produce   4   offspring   each   year   (2   male,   2   female).   Also   
assume,   that   all   births   happen   in   the   last   hour   of   the   last   day   each   year   and   the   
parents   die   immediately   after   offspring   are   born.

a)   How   many   rabbits   are   there   after   10   years?   
b)   How   many   rabbits   are   there   after   25   years?

If   they   have   20   offspring   each   year,   

c)   How   many   rabbits   are   there   after   10   years?   
d)   How   many   rabbits   are   there   after   25   years?

Question   2

Now,   assume   that   rabbits   reach   sexual   maturity   instantly   after   being   born   and   all   
can   reproduce   continuously   (generations   overlap).   If   each   pair   has 4   offspring   and   
both   parents   die   by   the   end   of   the   year:
   
a)How   many   rabbits   are   there   after   10   years?   
b)How   many   rabbits   are   there   after   25   years?

Question   3

Now,   assume   that   the   carrying   capacity   of   the   environment   is   K=1000.   There   are   6   
offspring,   both   parents   die   as   before.

What   is   the   rabbit   population   when   the   growth   rate   of   the   rabbits   each   year   is   the   
largest?

Use   discrete logistic   to   answer:

a)   How   many   rabbits   are   there   after   2   years?   
b)   How   many   rabbits   are   there   after   3   years?
