Final Programme, with list of Posters


Dear Colleagues!

We continue with the main idea from the 1st Symposium, to gather experts dealing with as many different aspects of invasive species as possible. The duration of the Symposium will be two days, and time of year remained the same as at previous Symposia, enabling presentation of the most recent collected data. We are planning to have good “old-fashioned” meeting in person.

Formatting your Abstract

Abstract should contain objectives, methods, results and conclusion. Be as specific as possible, avoiding purely descriptive and speculative content. At the end of Abstract, add 4-5 keywords (avoid words from the title).
Abstract (without title, authors and their affiliations) should not exceed 300 words. Title should be printed in capital letters. Write full names of the Authors (except for Middle names which should be with initials only). Do not use academic titles. If different, use number in the superscript to indicate different affiliations of the co-authors. Underline the presenting author.

You can use this template for formatting your abstract. Prior to sending please (re)name your abstract in the format "5CSIS-Abstract-Surname-Name".

Abstracts should be sent to this e-mail address till 17 September 2023. In case you haven't received confirmation of abstract submission within 48 hours, please contact Sven Jelaska.

Please indicate on top of your abstract preffered way of your presentation (oral or poster).

Scientific Committee can propose changes of the preferred way of presentation indicated by the authors, in which case these will be discussed with the authors.
Accepted abstracts will be printed in the Book of Abstracts only if registration fee is payed until 31 October 2023. In case of payments after the aforementioned date, we cannot guarantee the inclusion in the Book.
