EDITORIAL

It was advertised already in the previous issue of Psammonalia that the possibility is created to surf within the interstices of the sediments by reading Psammonalia on the internet Home Page. The Meiofauna WWW site is at http://inlet.geol.sc.edu/ ~nick/meiofauna.html
I thank Nikolaos Schizas (Univ. South Carolina and student of Bruce Coull) and our computer (and fish) man Kris Hostens very much for all the help since it was not an easy at all task to transfer it from the Network system of the University of Gent to the Home Page.
Some of you reacted already quite enthousiastic about the Home Page! Nevertheless, we have to consider the good and the bad things about this progress.
What do meiobenthologists want ?
We can save at least 300 US dollars per issue in production costs (fotocopies) and postage if all (?) the members can take the information from the web. Is this a sign to decrease the dues (which are very modest anyhow)? Or should we transfer the dues to the Swedmark Fund in order to encourage the study of meiofauna among students ? Anyhow, who will in the long run still feel the need to pay dues if all the information can be taken for free from the web ?
Perhaps we have to think all over again about the production of the four Psammonalia issues a year and should move after some period to the production of only one hard copy once a year with the synthetised information which has been put on the web.
You see, many possible strategies to follow, and therefore I would like to ask you to put your personal ideas on paper (or as a note on the web) or communicate to me through email (Magda.Vincx@rug.ac.be). I will summarize in the next issue about your opinions.
On the other hand, monitoring this web also takes a lot of energy and I'm not sure if Nikolaos Schizas can take that effort for the future ? Normally it should be a task of the editorial board but since Nikolaos was so kind to offer his support, we took it with both our hands.
The address list has been updated in the web. A revised copy will be sent to each of you early next year. For those of you who have no access to the web you can ask me for information of course.
In order to obtain your ideas about the subject I ask the members of our organisation to comment on the following items :

1. Psammonalia should be put on the web
              YES/NO
2. If yes, Psammonalia on the web will replace the paper copy issues
              YES/NO
3. Part of the information of Psammonalia is put on the web
              YES/NO
4. Only member-address list is put on the web and can only be updated by the web-manager
              YES/NO
5. Only references of recent literature is put on the web
              YES/NO
6. Both address list and recent literature is put on the web and will be updated 4 times a year
              YES/NO
7. Psammonalia fees are still needed
              YES/NO
8.Only those who want a paper copy, have to pay for their issues, others can have a reduced fee or free of charge
              YES/NO
9. In the future (to be decided on the next meiofauna meeting in Plymouth (1998)) we have to change our product
              YES/NO
10. For the next three years Psammonalia will be produced both on the web and on paper and send to the members
              YES/NO
11. I do not need to receive paper copies from now on and the saved money can be put on the Bertil Swedmark Fund
              YES/NO
12. Any other suggestions ?

Looking forward to a reply on this important issue by ALL OF YOU !!!!

Activities at the Limnological Institute of Mondsee (Austria)

Prof. Dr. Dan L. Danielopol is working on a new interdisciplinary project on groundwater meiofauna from the Vienna area. His group (P. Posipisil, F. Mö lacher and J. Dreher) is now investigating the adaptations of local populations to three types of surface alluvial environments. He is also directly involved, together with his colleagues A. Baltanas (Univ. Autonoma de Madrid) and P. Marmonier (Univ. Savoie), in the morphological differentiation of local populations of a groundwater ostracod species. Another project deals with cladistic analysis of Ostracoda.

Friederike Mösslacher is working on her PhD-thesis on physiological adaptations of groundwater species and populations. Adaptations of Copepoda living in different subterranean and surface water habitats are investigated. A comparison of the metabolism, the breathing strategy, and survival rates at different oxygen saturation levels is made. Furthermore her thesis will be completed with work on groundwater organisms and with an attempt to use this information for biomonitoring.

Christian Griebler succesfully adapted a method (DMSO reduction method) from soil microbiology for the determination of the microbial activity in freshwater sediments. Previously this method was used to investigate effects of bioturbation by tubificid worms on mixed microbial assemblages. Within his PhD-thesis the DMSO reduction method is now modified for its use in freshwater.

Dr. Peter Pospisil is currently involved in a research project managed by Prof. Dr. Dan L. Danielopol. This project focusses on the groundwater cyclopoids of Vienna, especially on the Diacyclops languidus/languidoides-group which has at least five representatives in our 1km2 research area. Some of the problems which have to be treated are: 1. Explanation of their different small-scale distribution patterns using field data and laboratory experiments (response to oxygen depletion, temperature variations etc.); 2. Survival strategies to cope with hypoxic conditions of the groundwater during the warm season; 3. Monitoring of short-time oxygen fluctuations in groundwater habitats close to and more distant from surface waters; their influence on animal abundance and distribution; 4. Detailed examination of the "species"-status of the five Diacyclops-morphotypes by means of morphology, morphometry and electrophoretic investigations.

Interests: From April 1988 to April 1993, I carried out my biology studies at the University of Hamburg (Germany), focussed on hydrobiology and oceanography in the last two years of the studies. From April 1993 to April 1994 I did my MSC about the reaction of meiobenthic communities on beach nourishment at the westcoast of the Island of Sylt (North Sea). To proceed in this field I developed the hypothesis that reactions of meiofaunal communities to different types of natural and man-induced disturbances are specific and result in characteristically structured communities. Since June 1995, I am doing a PhD on the effects of disturbances on meiofaunal communities at the Plymouth Marine Laboratory under the supervision of Dr. R.M. Warwick (PML) and Prof. Dr. H. Thiel (University of Hamburg).

QUIZ

Quiz-question of issue 111 was : Identify this animal !

A few people mailed me an answer, and thus here follows a reflection of the true spirit of some of our fellow IAM members :

* Rhian David (London, U.K.) :
'Is it a Draconema nematode?'

* Rick Hochberg (Arcata, USA) :
'The organism appears to be a nematode of the genus Dracograllus. A very interesting animal indeed! Would love to run into it in California. Take Care.'

* Steve Jarvis (c/o G.E.L. Harker; U.K.) :
'I liked your quiz picture in the last Psammonalia. Could this beast be "Draconema"? Regards'

* Greg Street (Texas, USA) :
'My guess for the beast on p.9 is Hallugenia, the fossilized onycophoran from the Burgess Shale. I believe current opinion is that the animal's feet are the small, dorsal protrusions and the "legs" from the illustration are actually dorsal spines.
Hopefully, I am wrong, and it is actually a meiobenthic animal.
Great job with the issue!

* Guglielmo Tita (Quebec, Canada) :
'After a long and very deep research (references were not easy to find), it seemed clear to me that the animal drawn on Psammonalia no. 111 was the very rare species of Nematosaurus polypodatus.
First description was given by Aristotle in 322 b.J.C. just before his death. The latter was probably caused by N. polypodatus (Wife of Aristote, 315 b.J.C.).
More recent studies (not published) include N. polypodatus in the trophical group of "very carnivorous".
Its habitat is tipically the very complex system of dreamland, nevertheless it seems to be able to live within marine sediments. Take care of you !!!'

* Donald J. Zinn (Falmouth, MA, USA) :
'The animal on page 9 of Psammonalia # 111 is probably the nematode Bathyepsilonema spp.'

The true origin of the drawing has to be found in the genus Polkepsilonema Verschelde & Vincx, 1993, a member of the Epsilonematidae, of which (take care, here follows the answer) I drew a cartoon version with slightly exaggerated 'legs', creating an animal from past times which I baptised Tyrannonema rex, for some obvious reasons (imagine it being a six meter large nematode!).
I must say that I was very pleased with all answers and reactions, and that the wit of especially both Greg Street and Guglielmo Tita made me smile for more than a week. So I have to say a big Thank you to all participants of last issue's quiz-question.
But due to both the speed and correctness of the answer of the following contestant, we have to declare our glamorous winner:

Heino Christle (Germany):

'My suggestion concerning the quiz-question of the month may be not the most creative one, but it is quite easy to see that it must be the extinct ancestor of both Nematoda and Archosauria, one of the famous missing links called Tyrannochaetosoma rex.
I guess it's the ssp. millipedia, as it bears more than one pair of hind-legs.
It seems being a dangerous predator: Its mouth-opening is much bigger than that of recent Epsilonematidae. I still wonder if its mouth-cavity will bear teeth. In Tyrannosaurus rex it does, in Desmodorids usually not.
All the best to you, Yours Heino.'

For the new Quiz-question, I would like you to recognize and reflect on the following enlarged part of a drawing which will be the cover of the next issue of Psammonalia (# 113). Again we are eager to receive your wity reactions:

Send your email answers to :
Dominick.Verschelde@rug.ac.be

Answer in next issue of Psammonalia, together with a honoury citation of this month's winner.

By the way, by the time you will hear new news from your quiz-master (issue 113), your humble 'production editor' (that's me) will be a married man : I am getting hitched on the first of June, 1996; so 'life will never be the same again'! I hope we can get some sun for that day, as it has been raining in Belgium for the last two weeks now.

THANKS
This issue was also made possible due to the help and effort of the following members :
