Rule 18 of the satutes of SIL states; "Each member attending a Congress shall be entitled to present one paper".

It is a SIL members right to persent a paper at a SIL congress, however, the LOC can accept it either as an oral or a poster presentation. 

Instructions for Abstract Submission

According to the statutes of SIL, a member when attending a congress is entitled to present a paper. As with previous congresses this tradition within SIL will be honoured.

2. The title must be in Bold Capital Letters and must reflect the contents of the presentation.
3. List the Authors and underline the presenting author.
4. List the institution(s) using numerical numbers to identify more than one author.
5. The abstract should briefly describe the main questions and findings. It should not exceed 200 words.

The role of algal toxins and their production are poorly documented and understood. The mechanisms of “switching” the toxicity “on” or “off” are largely unknown, as well as the variance in toxicity within a specific strain. We grew several Microcystis strains, measured the microcystin contents as well as their growth characteristics. Large variations were found that has important practical value. The molecular basis of toxin-production in M. aeruginosa has been partially elucidated. Using PCR’s and AFLP assays it was possible to determine the genetic relationships of the geographically unrelated strains. Analysing the strains and using the insertions/deletions to discriminate between natural strains, the value of PCR assays as an indicator of toxicity and taxonomical characteristics were confirmed.

Please email your abstract(s) to: as an MS-Word attachment
