GAS President's Comments AND
REPORT FROM THE ACADEMY COUNCIL
We are looking forward to having an excellent 81st Annual Meeting of the Georgia Academy of Science to be held March 26-27, 2004 at Berry College. The Local Arrangements Committee has been working diligently over the past few months and has designed a very impressive website for the event. Please link to the Berry College website through the Academy website or view it at the following address in order to get up-to-date information: http://www2.berry.edu/academics/science/gasci/ . One highlight of the meeting will be the Plenary Session lecture given during the luncheon on Saturday. Dr. Harvey T. Holmes, Deputy Chief of the Laboratory Response Branch, Bioterrorism Preparedness and Response Program at the Centers for Disease Control and Prevention will be speaking on the topic of "Smallpox: From Ancient to Modern History." He will be giving an overview of smallpox from its origin to eradication and the consequences of the re-introduction of the vaccine. Dr. Holmes has the reputation of being a thought-provoking speaker and his presentation should be of great interest to the general scientific community.
We are hoping to have a significant number of papers being presented at the meeting in all areas of science and invite faculty and students from around the state to attend and network with others scientists in their fields. Remember that presenters are invited to submit a manuscript based on their presentation to the Georgia Journal of Science for publication, based upon review, in the issue following the Annual Meeting. The Journal provides new and upcoming researchers (as well as "seasoned" scientists) the opportunity to publish their research results in a refereed scientific publication. Information for authors can be found inside the back cover of the Journal. I especially encourage undergraduate and graduate students to publish their papers in the Journal. It is a wonderful way to begin their scientific careers and allows a paper to be published in a timely manner.
As a final note, I want to say that it has been a privilege to serve as the Academy president this year. I would like to thank all of my colleagues on the Council for their advice and help throughout my term and would like to especially thank Steve Whittle for agreeing to take over as Technical Program Chair this year. There are others, such as the Editor of the Journal, John Aliff, who have worked many years with the Academy and who should be recognized for their tireless efforts. I extend my thanks to each of you and wish everyone a joyous and restful holiday season.
Lisa B. Hibbard, President
The Georgia Academy of Science will hold its 81st annual meeting on the campus of Berry College just outside of Rome, Georgia on March 26 and 27, 2004. The nine sections of the Academy will hear papers and view posters presented by science students and faculty from Georgia's colleges and universities on Friday afternoon and Saturday morning. A dinner followed by a talk (speaker not yet named) will conclude the events of Friday evening and Saturday's session will end with a luncheon, the annual business meeting of the Academy, and a lecture.
The site of the meeting, Berry College, is especially beautiful in the spring and the ample campus and adjoining forests serve as a laboratory for outdoor studies. In addition, the Rome area boasts several recreational, educational, and cultural sites.

TEACHING COLLEGE ALGEBRA USING SUPPLEMENTAL
INSTRUCTION VERSUS THE TRADITIONAL LECTURE METHOD

Corresponding author: Andreas Lazari
Trying to improve students' academic success has been the focus of many universities across the country. The success of a student begins in the classroom. One of the most troublesome and sometimes terrifying course for students is College Algebra. At Valdosta State University we have tried different methods such as a WEB delivery course and teaching with computerized instruction to improve students' success. For the past two years, at Valdosta State University the Department of Mathematics and Computer Science has been teaching College Algebra (MATH 1111) via a Supplemental Instruction (SI) method. The students' performance on the departmental final exam for the treatment group, SI method, versus the control group, traditional lecture method, was compared. The SI method showed no significant difference on the departmental final exam. Then we compared the mean SAT scores for the two groups. The SI method showed significantly lower SAT scores. It is clear that weaker students in mathematics that take the SI courses can perform on the average on the final exam just as well as the students in the traditional courses.
Key Words: teaching college algebra, lecture, supplemental instruction.

Forty-five photoelectric magnitude measurements of Saturn were made between Oct. 31, 2002 and Feb. 24, 2003. The normalized magnitudes, at a ring tilt angle of B = 26.5°, were: B(1,0) = -8.75±0.02, V(1,0) = -9.77±0.01, R(1,0) = -10.43±0.01 and I(1,0) = -10.65±0.01 while the corresponding solar phase angle coefficients were: cB = 0.045±0.007, cV = 0.035±0.005, cR - 0.031±0.002 and cI = 0.027±0.005. At least four oval storms on Saturn were imaged in late 2002 and their average area was 18 x 106 km2. Storms and other features on Saturn did not have an impact on that planet's brightness and color.
Key Words: Saturn, Photometry, Saturn storms.

A community analysis was performed on a 0.75 ha forested area in order to gather baseline data for a newly formed environmental preserve in Bartow County, Georgia. A total of 17 different woody species were observed. Dominant woody species were Oxydendrum arboreum (L.) DC., Quercus alba L., and Pinus echinata Miller. Two pairs of species with similar ranges and ecological characteristics were compared. The first pair of species were the broadleaf species Nyssa sylvatica Marshall and Acer rubrum L., and the second pair were the pine species Pinus taeda L. and P. echinata. Within each pair species showed opposite trends in importance values with increasing distance from a reservoir. For N. sylvatica and P. taeda, importance values increased, whereas for A. rubrum and P. echinata importance values decreased with distance from a reservoir. Pinus echinata, P. taeda, and A. rubrum had even distribution patterns, whereas N. sylvatica was randomly distributed.
Keywords: Pinus taeda, Pinus echinata, Acer rubrum, Nyssa sylvatica, community structure.
SIZE AND AGE CLASS ESTIMATES OF NORTH AMERICAN
EOCENE PALAEOPHEID SNAKES

In North America, two genera (Palaeophis and Pterosphenus) and six species of palaeopheid snakes are known from Gulf Coast and Atlantic coastal Eocene marine or marine-influenced sediments. They were specialized aquatic snakes that today are known almost exclusively by isolated vertebrae. Using vertebrae of living boids (Boidae: Boinae) of known lengths and age classes as models, lengths and age classes of the six North America palaeopheid species were estimated. In some cases body morphologies were suggested. As adults, the largest species were Palaeophis grandis and Pterosphenus schucherti, each at about 5.1 m (17 ft), while the smallest species was Palaeophis casei at about 1.3 m (4.3 ft). For the first time, adult, juvenile, and neonate size classes are identified for Palaeophis virginianus.
Key words: palaeopheid snakes, Eocene, sizes, age classes, North America.
FOOD PREFERENCES AND BIOENERGETICS OF THE
WHITE-FOOTED MOUSE (PEROMYSCUS

This investigation focused on the food preferences and bioenergetics of the white-footed mouse (Peromuyscus leucopus) and the golden mouse (Ochrotomys nuttalli), two small mammal species with similar life histories and extensive niche overlap. Water oak (Quercus nigra) acorns, white oak (Quercus alba) acorns, and Chinese privet (Ligustrum sinense) berries comprised the study diet. White-footed mice showed significantly greater mean ingestion, assimilation, and respiration values than did golden mice, suggesting greater movement and feeding behavior under field conditions.
Key words: Peromyscus leucopus, Ochrotomys nuttalli, food preference, bioenergetics.
