Question  8  

Ecology  and  Conservation>    

A  biologist  originally  marked  40  butterflies  in  Wilson  Park.  Over  a  month  long  period-­‐butterfly  traps  caught  200  butterflies.  Of  those  200,  80  were  found  to  have  tags.  Based  on  this  information,  what  is  the  estimated  population  size  of  the  butterflies  in  Wilson  Park?    

Answer:  100    

Page 3: BIO153 Exam Jam

(Population  size  using  formula  >  mark  and  capture)
