1Participation includes attendance on the 2 field trips and facilitating a discussion on an amphibian paper.  You will earn 5% and 2.5% for attending each field trip for WFS 433 and 533, respectively.  For the Discussion, you will earn 10% and 5% for leading in WFS 433 and 533, respectively.   

2If you miss a field trip, you can either: (1) attend the SE PARC meeting, (2) write a 10-page scientific paper on an amphibian topic of your choice, or (3) accept the percent deduction (5% or 2.5%) in your final grade corresponding with the appropriate course number.

3One hour lecture on an amphibian topic – please see full syllabus for a list of available topics.

Extra Credit:             

 

You can positively influence your final grade as much as 4.5% by volunteering for extra credit.  Volunteer work must be related to herpetofauna, and can include work on university projects, government agencies or NGOs.  For every 8 hours of volunteer work, your final grade will be increased by 1.5% up to 4.5% (24 hours total).  All volunteering must be completed by 25 April 2008.  A volunteer form (see website) must be filled out by the supervising individual.  Scott Dykes and Pete Wyatt (TWRA non-game biologists) often are looking for volunteer assistance (Region 4 Office: 1-800-332-0900; scott.dykes@state.tn.us, pete.wyatt@state.tn.us).  Also, Wayne Schacher (consulting biologist for Seven Islands Wildlife Refuge) frequently needs help with herptofaunal surveys (457-4355 home, whschacher@natreserv.com).  Bridgid Lammers (graduate student in the UT Wetlands Program, blammers@utk.edu, 974-3897 office) needs assistance collecting tadpoles on 18-20 and 25-27 January and mid-late April 2008 (see flyer: http://fwf.ag.utk.edu/mgray/wfs493/TadpoleFlyer.pdf).  Lastly, you can earn 1% by attending Dr. Rick Relyea’s talk on Friday, 4 April, in 307 Science & Engineering Building at 3:30 pm.

 

Extra Credit Form

 

Extra credit also can be earned by attending the Annual Meeting of the Southeast Partners in Amphibian and Reptile Conservation: http://www.separc.org/.  It is 21 – 24 February in Athens, Georgia. Your final grade will be increased by 3.5% for attending.
