Dear colleague,

The Institute of Marine Biology, Russian Academy of Sciences, Far-Eastern Branch, the A.N. Severtsov Institute of Ecology and Evolution, Russian Academy of Sciences, the Institute of Biology, Karelian Scientific Centre, Russian Academy of Sciences, the State Natural Reserve ‘Prisurskii’ and the National Library of Chuvash Republic invite you to take a part in Eleventh International Symposium of the Russian Society of Nematologists «The nematodes and other Ecdysozoa» which will be held in the period July 6-11 2015 in Cheboksary, Chuvash Republic, Russian Federation.

A wide spectrum of scientific issues will be considered in the course of the meeting. The symposium will provide nematologists the possibility to share their views on the recent progress in nematology, present their results as oral talks or poster presentations. One of the goals of this meeting is the strengthening of the professional links between Russian and international nematologists.

Within the frames of this scientific meeting a workshop on theoretical and applied nematology will be organized for the undergraduate and postgraduate biology and agricultural science students.

The symposium will be held at the facilities of the National Library of Chuvash Republic at Cheboksary.



Main topics of the symposium:

Nematodes and other pseudocoelomate animals in the Animal Kingdom.

Phylogeny of nematodes.

Morphology, embryology and ultrastructure of nematodes.

Ecology, biology and diversity of nematodes.

Biochemistry, physiology and molecular biology of nematodes.

Nematodes as bioindicators in fresh-water, marine and terrestrial ecosystems.

Invasive nematode species. Quarantine measures. Nematode population control.

Working languages of the Symposium are English and Russian.

The cultural program of the meeting will include the excursion around Cheboksary, acquaintance with the ethnic history and modern life of Chuvash people, and the trip to Kazan, the capital of neighbouring Tatar Republic.

The meeting of the members of the Russian Society of Nematologists will be also organized to discuss current problems and targets for Russian nematology.
Participation in the Eleventh RSN Symposium can be done via online registration at the official website of the meeting - http://ISRSN2015.rusnema.com up to April 1, 2015, or by sending the completed registration form (presented on the last page of this circular) by electronic mail to rus.nema15@gmail.com.

Registration fee for the participation in the Eleventh RSN Symposium is 270 euro and will cover all the common expenditures of the Symposium: printing of abstracts and other materials, correspondence with participants including the express mail for delivery of official invitations (needed for Russian visa application); regular expenditures during sessions (meeting rooms rent, translation, coffee breaks, refreshments); organized lunches for foreign participants at the 1st, 2nd and 4th days of the Symposium; a bus tourist trip to Kazan on the 3d day of Symposium including visit to the local ethnographic museum and the farewell banquet
Registration fees can be paid ONLY through the account of the Russian Journal of Nematology.

Please mark the money transfer as ‘Registration fees RSN 2015 Symposium’
The payment is to be made before April 1st, 2015. After this date the registration fee will be 290 euro.
All the needed information about hotels and entertainment possibilities in Cheboksary, easy ways to reach this city in the Russian Federation and other helpful sources and sites will be presented on Symposium site http://ISRSN2015.rusnema.com and in the next information letter.


The format of presentations

All the oral presentations of the main Symposium events are to be presented in English in Microsoft Power Point. Plenary (opening) talks are by the invitation of the Scientific Committee only (time for this type of presentation will be discussed separately with the invited lecturer). A session talk will be 20 min long (normally including 5 min for discussion). We expect that participants will provide the Organizing Committee with the files of Power Point Presentations during the registration, to ensure the safe uploading of files into symposium computers.

For the poster presentation a surface of 1 m wide and 1.2 m high will be provided. The preferred format for poster presentations will be available on Symposium website after Jan 1, 2015.

The abstracts of talks and presentations are expected from participants before April 20th, 2015.

Abstracts of all presented talks and posters will be printed in the Russian Journal of Nematology, 2015, vol. 23, N 2.

The style and format of the abstract is presented below. The upper limit of abstract text length is 250 words.


Yushin, V.V.1, Claeys M.2 and Houthoofd W.2. Mature spermatozoa of Brevibucca sp. (Nematoda: Rhabditida: Brevibuccidae).


The nematode family Brevibuccidae Paramonov, 1956 has questionable relationships within the order Rhabditida (sensu De Ley and Blaxter, 2002); new information on morphology of the family representatives is desirable. The spermatozoon morphology and development have potential to be used as clear and easily comparable morphological characters in taxonomic and phylogenetic analysis. We present the original study of Brevibucca sp. (SB117) sperm ultrastructure as the part of the international project on nematode reproduction. The nematode spermatozoa represent an aberrant type of male gametes; they are characterized by the absence of an axoneme and acrosome. The mature spermatozoa of Brevibucca are amoeboid bipolar cells ca 4.3 µm in size; each cell is subdivided into a pseudopod devoid of organelles and a main cell body. The main cell body includes a condensed nucleus, many mitochondria and so called ‘membranous organelles’ (MO). These unique, aberrant, organelles are characteristic to developing as well as mature sperm of many nematodes studied. The MO in Brevibucca sperm look like large (ca 0.6-1.0 m diam.) vesicles with transparent content and a system of internal finger-like projections of the outer membrane. Each MO is joined to the plasmalemma of the main cell body and open to the exterior via a pore. Each spermatozoon has a prominent pseudopod filled with the filamentous components of the cytoskeleton. The spermatozoa of this type have been described in representatives of several higher taxa of the ‘rhabditids’ (Spiruromorpha, Ascaridomorpha, Panagrolaimomorpha, Tylenchomorpha, Diplogastromorpha, Rhabditomorpha) and are known for free-living marine species from the orders Monhysterida and Araeolaimida.
