  2. 10,000
  3. 100,000

What would the extinction rate be for a 30 square mile island that is 1000 miles from the mainland and has 150 species on it. Assume the extinction probability for each individual species is 0.8 and the power scaling function is 0.25. Round your answer to two decimals, include a 0 before the decimal if necessary, and do not include units (i.e. O.XX)
If 99% of the species that ever existed are now extinct, why is there such concern over the extinction rates over the last several centuries?
Since 2000, three mammal species have been declared extinct by the IUCN: the Bramble Cay melomys (Melomys rubicola), Christmas Island pipistrelle (Pipistrellus murrayi) and the Saudi gazelle (Gazella saudiya). What is the extinction rate of mammals, in MSY, since 2000 (+/-0.01)? Assume for our purposes that 5,436 mammals have been monitored over the past 20 years.
