 __Before reading__  deep, animals, water, ocean, river, species, tropical, equation, variable, fish *How can you use math applied to biology. Mention one thing you can think of. Using some equation that may reveal where a specific spicie is, or would be. *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. Is a invertebrate fish almost transparent with a lot of tentacles I think it's the distribution of something specific in a area.
 * Read the tilte and list 10 words you think you might find in the text.
 * 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 - species, ocean, waters, revealed. 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 ocean the Jellyfish  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. the movement of the jellyfish 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 harbours at the ships destination mid-ocean exchange 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. the computer model 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 non-natural dispersal happens with the jellyfish 4. What is happening with the fish? have been dispersal to differents places that it would not do in a naturaly way. 5. What explanation scientists had given? the international shipping by water 6. What did mathematicians find out? What does the formula explain? create a mathematical model of their dispersion over time. each experiment was based on the virtual release of 20000 lavae from know moon jellyfish zones of occurrence
