__Before reading__  *Read the tilte and list 10 words you think you might find in the text.  *How can you use math applied to biology. Mention one thing you can think of.  *What do you know about jelly fish? What kind of fish is it? If you don't know, find out, cut and paste an image of this fish. Please acknowledge the source.  *What is dispersion? If you don't know, find out, please acknowledge the source.

__While Reading and After Reading__  1. Click on the following link so that you can read the article.

 2. Try to locate the words you though you were going to find in the text (question 1 before reading) List the words you found  3. Find what the following referents in bold letters refer to in the text:


 * The species of Jellyfish studied are known as Aurelia and **these** are found over much of the world’s temperate oceans.
 * By simulating the movement of the jellyfish over a 7,000-year period the study provides strong evidence that the world-wide dispersal post-dates European global shipping and trade, **which** began almost 500 years ago.
 * Ships take in water for stability before a voyage and, despite preventative measures such as mid-ocean exchange/ flushing, **this 'foreign' water** and **its contents** can find its way into bays and harbors at the ships destination.

4. What is happening with the fish?  5. What explanation scientists had given?  6. What did mathematicians find out? What does the formula explain?
 * <span style="color: #0077ff; font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 9pt;">The computer model could answer similar questions about the migration and introduction of any suspected non-native marine creatures, according to **its** developers Professor Matthew England and Alex Sen Gupta.
 * <span style="color: #0077ff; font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 9pt;">Now we have a tool that can include data on currents, geography and the biology of an organism to help separate natural dispersal **from that which happens** through shipping and trade
