Fish Out of Water

A waterfall climbing cave fish found in Thailand has a primitive pelvic bone and fused spine that allow it to use each of four fins to navigate (rather than just pulling itself along on front fins).  It may be a link to a significant evolutionary adaptation:  the ability to walk on land.

Happy World Water Day!

Thanks so much to Janette Marsh from USEPA's Region 5 Chicago, Water Division for coming out with us today!  So cool that she told us how important your work is--getting to know your own watershed.

Here is the link she mentioned for USEPA water resources.

National Aquatic Resource Surveys

Help for Research Questions!

Liz and I enjoyed visiting all of you in class!  Sounds like you guys have a lot of great project ideas.  Here are some resources that might be helpful.

Lots of you are interested in water quality and pollution issues.   We will be learning more about that when you visit the ravine next week.  Meantime, the Illinois EPA monitors pollutants in Lake Michigan and you can find a lot of their information here.

Flooding is an issue dealt with by the Lake County Stormwater Management Commission.  They have a lot of good information about how rain gardens and other rain harvesting tactics can reduce stormwater runoff.

Salt is a pollutant in our fresh water.  Here is a paper on the Effects of Road Salt on Chicago water.
Here is an article about Highland Park's annual salt use.

If you want to know more about native and non native plants in the ravines, including aquatic invasive plants, go this page at www.pdhp.org.
