Workshop on Paleoecology of South Florida

 

Spring 2009  

Wednesdays 2-4:30 + 2 field days; class ends before Spring Break

Instructors:  Drs. Laurel Collins & Evelyn Gaiser

 

Biology Dept. Class Number 18958, BSC 5929 Workshop: Paleoecology of South Florida

Earth Sciences Dept. Class Number 18959, ESC 5162 Workshop: Microfossil Paleoenvironments

2 credits, no prerequisites

 

Course Description:  Hands-on fieldwork and labwork. Students collect living foraminifera and diatoms from Everglades marshes to Biscayne Bay marine sediments, and interpret paleoenvironments of a sediment core.

Learning Outcomes:  Students will be able to collect and record sediment and water samples, identify diatoms and foraminifera under the microscope, and know how to apply taxon distributions to the determination of paleoenvironments.

Reading

Handouts will be distributed during the workshop, including the following:

Diatom Indicators of Ecosystem Change... 

Diatom-based water quality...

Culver, Stephen J. 1993.  Foraminifera.  Pp. 203-247 in J.H. Lipps (ed.), Fossil Prokaryotes and Protists.  Blackwell Scientific, Boston.

  

Course Justification

This workshop teaches the paleoenvironmental knowledge and the taxonomic and laboratory skills necessary to interpreting paleoenvironments from sediment cores. Interpreting past marine, estuarine and freshwater environments of South Florida helps in restoration efforts of Florida Bay and the Everglades, and contributes to understanding future environmental changes.

 

 

Course Policies and Grading

 

The fieldwork is mandatory unless a serious issue such as a medical condition prevents it.

Grades will be based on the following 3 components:

50%     prepared and identified diatoms and forams from 2 samples

30%     3-5 page report on the workshop, including a description of the gradient in species composition with changes in the modern environment, a table of key species distributions, and interpretation of change in environment, if any, in the area represented by the core. The organization of the paper should be the following: Abstract, Introduction to study area and questions addressed, Methods, Results, Conclusions, References, and a map and table. A hard copy of the report is due by Friday, March 13 at 5 pm in either Dr. Collins' or Dr. Gaiser's office.

20%     participation in fieldwork, classes and labs
