The EEB Graduate Student Symposium is an all day event where graduate students present their research to other graduate students and faculty. Any EEB graduate student can present: BSMS, masters, PhD, old and new students. New graduate students usually present research ideas or preliminary data, while those more ‘seasoned’ students present their most recent results, often in preparation for upcoming spring and summer meetings.

We would like to invite all EEB graduate students to give a 15min talk. Speed Talks have been seen at several large meetings over the last year (playing off the speed dating idea). These talks will be 3min presentation, PowerPoint optional. They are ideal for sharing side projects, amazing images or videos, great opportunities that others should take advantage of, or any other interesting things that you would like to share. Since this is new, we are going to have one small section of them in the afternoon. We envision these being given in addition to a regular 15min talk.

15min Talk Title Submission Deadline: TBA

Abstract Submission Deadline: Self-Submitted on EEBedia after the schedule is posted

What Bracteacoccus is not.
Traditionally, the classification of coccoid green algae depended on subtle morphological differences, without much information about the potential variation or plasticity of these traits. The use of molecular sequence data provides a high number of characters that are not subject to phenotypic plasticity and therefore are assumed to provide a more direct measure of phylogenetic relationships. Molecular phylogenetic studies of coccoids often yield unexpected results, uncovering cryptic diversity as well as placing taxa in dramatically different positions from those expected under the morphological paradigm. As part of a monographic study of the chlorophycean genus Bracteacoccus, several strains deposited in culture collections under this generic name were found to belong to other green algal genera. Although morphologically similar to young cells of Bracteacoccus, these algae were demonstrated to belong to the genera Myrmecia and Pseudomuriella based on 18S and rbcL sequence data. These cases may represent two of potentially many discrepancies of morphological and sequence data.
