Assignment:

Liz sat at a table in the student union enjoying a cup of coffee and flipping nonchalantly through her vertebrate biology textbook. She had a paper due in two weeks and still had not decided on a topic. Her instructor focused mainly on taxonomy and anatomy in class, but Liz was more interested in ecology. Her friend Abby, carrying a tray with an enormous cinnamon roll, sat down across the table.

"Still trying to figure out a topic for your paper, Liz? Why not follow up on those antifreeze mechanisms in Antarctic fishes?"

"I thought of that but I don't want to get into all that cell biology and chemistry. I'm more interested in whole organisms that I can see; like, maybe those marine iguanas in the Galapagos. Dr. Parisi had some pictures of them from a trip she took in 1999. She said that there were a whole lot less of them than she expected, and the guides told her that most of the islands had 40-90% mortality in the previous year."

"What could have killed the iguanas that fast?" exclaimed Abby as she pulled her laptop out of her backpack. "Just a minute while I Google the Galapagos." Abby quickly found a map of the Galapagos archipelago.
