Reading log 1 - Using Mathematical Models to Study the Dispersion of Exotic Marine Species ** __Before reading__ I guess I'll find word as "probabilities", “aquatic creatures”, “reproduction”, “temperature”, “salinity”, “predicting behaviors”, “habitats”, “genetic information”, “fish”, “availability of food”. I know two different ways: first- Applying probabilities to genetic inheritance models (Mendel's Laws), second- calculating energetic levels of organic molecules through matrices containing some data referred to those molecules.

Dispersion is the process in which animal or vegetal species that usually live in a place starts occupying different spaces because some individuals move there and continue reproducing.

2. Try to locate the words you thought you were going to find in the text (question 1 before reading). List the words you found It’s mentioned “water temperature”, and there also a paragraph containing the phrase “genetic data” instead of “genetic information”. I didn’t find any other word. - 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.
 * These ** makes reference to the well known species of Jellyfish named Aurelia.

**  ** 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 harbours at the ships destination. ** This foreign water ** refers to the water ships take in before a voyage and **its content** refers to everything that comes in that water, as animals, plankton, or minerals. · 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. ** Its ** refers to a computer model (previously mentioned) that could answer questions about migration and dispersion of species about time.
 * Which ** refers to the world-wide dispersal caused by global shipping and trade

· 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. 4. What is happening with the fish? It is happening that researchers found out the dispersal of Jelly fish was over the natural one, and they concluded that shipping and trade in the ocean was affecting natural dispersal, multiplying it, so jelly fish in now found in oceanic water her it could have not migrated naturally. 5. What explanation scientists had given? They explained shipping modified the dispersal process because ships take in some water before any voyage and the, water exchange at the middle of the ocean, meaning flushing water and all its contents in the ocean and taking in new one, has moved a lot of species-including jelly fish- from one place to other far away. 6. What did mathematicians find out? What does the formula explain? They find a formula to estimate and predict dispersion of jelly fishes about time. The formula explains that world-wide dispersal of the jelly fish started after shipping, almost 500 years ago.
 * That which happens ** refers to unnatural dispersal, caused by shipping and trade
