FINAL Manatee Migration Update: May 5, 2004

Today's Report Includes:


Special Thanks to the Scientists!
As our manatee migration season comes to a close, please join us in sending a HEARTFELT thank you to our dedicated scientists. In addition to their already busy jobs, each found extra time to share their research and knowledge with us. Journey North would not be possible without the dedication of scientists like these.




Thank you

Hi Students:
When you are busy with your summer vacation, we will still be busy with our manatee tracking research. In fact, we'll have even more to do, because Jim Reid and I just captured and tagged four more adult manatees at POI, for a total of ten manatees "online". These latest captures were kind of a last effort to increase the number of tagged manatees for our TTI study, since this will be our last year of that study (see below).

Some manatees are now carrying GPS transmitters, which can generate many more location coordinates than PTT transmitters do. Want to see the difference? Just take a look at the maps of Belvedere's GPS track this season in our summary of the TTI study below. You'll see the number and detail of locations mapped. Can you see how GPS gives us a very detailed picture of Belvedere's habitat use and how he traveled from place to place?

Since our last update, this season's tracked manatees have pretty much stayed put, with no real surprise movements. Take one last look at their locations in the final tracking data and maps from today's report:

What Have We Learned from the TTI Tracking Study?
After four seasons of radio-tracking manatees in the Ten Thousand Islands region, this research study is in its final season. What do the data tell us? Why are they important? And how will they be used? To find out, take a look at our TTI Summary.

So Long for Now
It is hard to believe that our time with you has come to an end. Every year the season seems to go by quicker and before we know it, it is time to say goodbye! We have had a wonderful time working with all of you and we are continually amazed by your knowledge and understanding of manatees (we know this by your answers to those Challenge Questions!). We hope that you will continue to learn about manatees and their habitat and help us in our conservation efforts.



We have really enjoyed tracking the manatees with you and hope that you have too!

We look forward to working with Journey North again next year and hope that you will come back and visit!

You're the Scientist: Comparing Two Seasons of Migrations
One of this year's Manatees - Actual - was already tracked by Journey North students during the last two years. This gives you a rare opportunity to compare a manatee's movements over several seasons. It's also a chance to try and create your own hypotheses, then test them and learn whether you were right, or if you now have even more questions.

Follow the trail and the timing of Actual's migrations over several seasons. Ask yourself these questions: Did she generally stay in one area? Or migrate widely? Make big movements? Or make small movements? Did she visit any place more than once? Use the Lesson below to guide your inquiry.

Extension: Comparing Spring Migrations
After your students have finished comparing migrations over several seasons, have them write a scientific paper about their hypotheses:


Ranger Wayne's Farewell and Season Summary

Hi Kids!

It's been great to have you studying the manatees at Blue Spring again this year. I hope you have learned a lot and enjoyed yourself too.

Take a look at my full season summary below. It's always amazing what the weather and temperatures do to the manatees!

Three season records were broken at Blue Spring this year.

Do you know which ones?

If you get a chance next fall or winter, come for a visit. Have a great summer!

Try This! The Match Game: Can You Make a Match?
This season we've looked closely at Manatees and seen some very unique abilities from head to peduncle! Could you do some of the things Manatees do everyday?
  • Stay under water for 15 minutes?
  • Get new teeth constantly?
  • Exchange almost all the air in your lungs in just one breath?
  • Adjust your body fat to the surrounding temperature?
  • Eat 10% - 15% of your body weight in food each day?

A Manatee easily does all these things and more, thanks to special adaptations. But you would need some help to do the same things! Imagine yourself doing the things that Manatees do.



Try This! Pop Up Quiz: True or False
Think back on all that you've learned about manatees, and try to answer these "true or false" questions:
  • Pop Quiz

    Then discuss your answers in a group, and find out why you answered the way you did, and what really is the correct answer. Are there any answers that you can't agree on? Why?

Because They Are Endangered
As we wrap up this season, we must never forget that the Manatee is an endangered species, and we are lucky that it still exists on our planet. This is especially true when you remember that in some years the toxic algae blooms known as red tide can wipe as many as a hundred manatees. Learn More:
How can something so small, "bloom" into something so big?

What is Red Tide?


What if Manatees Had a TV Show?
If a single thing was causing 25% of all human deaths, we'd be pretty worried about that and action would be taken. Similar responses have happened for other animal species like dolphins or primates. Why not for manatees? (Afterall, since 2001 a single cause, powerboats, has annually caused between 19% to 31% of all deaths.) Is it because they've never had a TV show? Do manatees really need more protection? Learn more:


What if Manatees had gotten their own TV show, like Flipper?

What You Can Do

Each of us can take an active role in trying to save the manatees, no matter if we are students, or teachers or parents.


Ready for Summer Vacation?
As you finish up school and get ready for summer, ask yourself how is a human vacation different from an animal migration? For example, have YOU ever traveled without a suitcase? When people go on a trip, a lot of planning and preparation takes place. How about a manatee? Compare and contrast the purpose of travel, the preparations required, and the consequences of any mistakes. You're sure to appreciate an animal's remarkable journey even more after comparing their abilities to our own.

Sharing the Planet: 200,000 More People Every Day
As we end another manatee season, consider what human resource use and population growth mean to all living things. How fast are humans being added to the planet? Listen carefully:

Every time you hear a beat, it means there's another person on the planet. (This is not the birth rate, but the "net gain," which means births minus deaths.) If you were to count the beats for 24 hours, 200,000 more people would have been added to the planet.
