Artedi lives … again

On the night of 27 September 1735 suddenly ended the life of one of the most significant founders of the science of systematic biology when Petrus Artedi, Angermannius, drowned in a canal in Amsterdam. At the age of 30, he was still not a man of fame, and did not leave wife, children or portrait. Only manuscripts, the ichthyological ones edited and published by Carl Linnaeus in 1738.

Since 1738 every scrap of information about Artedi has been carefully collected and arranged by ichthyologists and historians of science into a puzzle still full of lacunae. The big questions have been – who was this person? What would he have become had he lived on? Was Linnaeus really the genius, or was it Artedi? After all, Linnaeus is the baroque idol of the cultural wannabe élite. But in a scientific context he is but one in a web of masterminds continuously occupied with reconstructing the history of life on Earth.

In his mystery novel The curious death of Peter Artedia mystery in the history of science (222 pp., Scott & Nix, New York, 2010) Theodore W. Pietsch, ichthyologist, professor at the University of Washington in Seattle, tells the story again, this time in the hand of Carl Linnaeus, in Linnaeus’ characteristic egocentric, bombastic, voluptuous, but yet flowing and elegant fashion.

We already know how it ends, or do we? The curious death of Peter Artedi is a story about a crime (or is it?), an 18th Century mystery (or was it?), with all the information put together, with  the whole 18th Century  Western Europe baroque academia and naturalists as background actors in the drama of  the two Swedish student friends (or competitors?). One dead and forgotten. One glorified in eternal life. Or, why some of us cannot forget Artedi? Ted Pietsch has spent years on researching Artedi and Linnaeus, visiting the historical places and analyzing their publications and all the little documentation otherwise saved from Artedi. This book is his conclusion, and you have to read it.

Artedi in love? In another novel, Peter Artedi Helenas son (Peter Artedi, Helena’s son), by Gun Frostling (202 pp., Nomen förlag, Visby, 2010),  Artedi on the run after an embarrassing experience with his father, takes in at a countryside inn. Suddenly he whispers to the innkeeper’s daughter Katarina Ersdotter, “We have to be careful, miss Katarina” …  The Katarina to whom he gives his final thoughts. Gun Frostling’s story is woven from the same fragmentary matter as all other Artedi biographies,  but gives him a real life on top of all the academic stuff, a real home, real parents, a loving girl, and spoken lines. And who is Gun Frostling? An author off the grid?

Beware, folks! Myths are coming to life here, in both those novels, fiction and facts creating a history of its own. Indeed, it may be time for the legend of Petrus Artedi to stand up against the icon of Linnaeus.

To conclude,  after all, scientists are people, human beings strong and weak in mind and heart as the wind blows this or that way. We have to remember that too.

Footnote: You can find those titles from practically any online book shop (in Sweden at least).

Mosioatunga, the true story

Dr Livingstone I presume is the archetype of  an explorer for most of us. The helmeted man at the head of the line of bearers fearlessly plunging into thick jungles to discover the world untouched by man.  That is the way they write their histories, and that makes for the books that sell. Of course, most of us now realize that wherever Livingstone and his likes went, there was already a human population. In East Africa at the time, there was both the native population, and considerable numbers of Arabian businessmen to show the way to all the discoveries the British needed. And help finding lost explorers from time to time.  The fact is probably  that the major contribution of western explorers was the mapping of the continents. During the 18th and 19th Centuries maps were drawn like never before, and it was new maps, not one more round of Europe encircled by the edge of the world.

Victoria Falls

The Center for the History of Science at the Royal Swedish Academy of Sciences is the guardian of enormous archives of objects, maps, drawings, and manuscripts that will eventually help toward understanding how our knowledge of the world gradually developed over the last few Centuries. The Center is highlighting some of its material as “object of the month”, since a few months back. One of these objects is a map sent to the Academy by Charles Andersson in 1852. It is a map made by Oswell and Livingstone  based on interviews with local informants. Interestingly, this map  of southern Africa from 1852 shows the Victoria Falls. The falls that, legend has it, Livingstone discovered in 1855. Not, he already had a map. The local name of the falls is now rendered as Mosi-oa-Tunya, on the old map they appear as Mosioatunga.

Portrait of Charles AnderssonAnd who was Charles Andersson, by the way? Some may be familiar with Oreochromis andersonii. That is the fish named after him, but somehow, the author, Castelnau, misspelt the name by dropping one of the ses in Andersson. Karl Johan Andersson, Swedish,born 1827 in the county of Värmland, was the son of the English hunter and writer Llewellyn Lloyd and a Swedish girl, Caisa Andersdotter. Lloyd spent most of his adult life in Värmland hunting bears and writing about it. Karl studied Zoology at Lund University and learned taxidermy at the natural history museum in Göteborg. He somehow got the idea of going to the Africa, and stranded already in London he became a friend of a distant relative, Francis Galton, yes the very one who discovered the fingerprinting technique. Galton and Andersson went to Africa, and Andersson spent the rest of his life as a trader, hunter, collector and more in what is now Namibia and South Africa, and much of that time in the field. Andersson was not an ichthyologist. He did collect a lot of birds. Not less than 2523 bird specimens from him are in museum collections (Dean, Sandwidth & Milton, 2006). He sent 200 or more specimens to the Gothenburg museum in 1864, but the curator there didn’t bother to open the boxes. Andersson wrote a classical travel book, Lake Ngami, published 1856, based on travels including to Lake Ngami (already ‘discovered’ by Livingstone). His second travel book, Okavango River, from 1861, relates his own major discovery, the river of the same name. Or … did he discover it?

Andersson’s zoological magnum opus, Notes on the birds of Damaraland, was published posthumously by  John Henry Guerney in 1872. Andersson died of dysentery and physical wounds in 1867 on his way back from a failed expedition to the Cunene River on the border between Angola and Namibia. Andersson’s life is full of misery, hardships, diseases, fights with employees and local chiefs, and the one drawback after the other. The most disappointing must have been the search for Lake Ngami, only to find it already found. It is a miracle he survived so long. His companion Axel W. Eriksson (1846-1901),  also Swedish, carried on the zoological collection and brought a huge collection of southern African birds to to Vänersborgs Museum in Western Sweden (available in an online database with images, all in Swedish).

The consensus (remember the map above) must be that there is (and was) nothing to discover on this planet, really. That is why science is not so much about discovery. It is about exploration and communication. Showing what the world is like, drawing the maps and fitting the pieces together. Also, life can be much easier than that of Karl Johan Andersson.

Eyebright – being an ichthyologist in the 18th Century

The latest issue of the annual proceedings of the Swedish Linnaean Society (Svenska Linnésällskapets Årsskrift, 2010) has an interesting article by Gudrun Nyberg bearing the title Ögontröst En biografi över naturforskaren Bengt Andersson Euphrasén 1755-1796. ( Eyebright A biography of the natural scientist Bengt Andersson Euphrasén 1775-1796. ) Euphrasén is (and was) one of the lesser known Swedish ichthyologists (although I bet most readers will be at a loss to call to mind any number of Swedish ichthyologist at all …). He did not live to see anything significant  ichthyological really accomplished, and his biography is verdict of that. Indeed he may be best known for his book about St. Barthélemy, mainly on plants. That would take us to a different story, though.

Euphrasén was born apparently 26 April 1755, son to a farmer in Myrebo (could translate to “Antnest” as well as  “Bognest”) in the western part of Sweden. Himself he seems to have lived in the illusion that he was born sometime  in April 1756. He was baptized Bengt Andersson. Somehow he was given a good education, attending boarding school on Visingsö Island from 1772 as Benedictus Arén Haboënsis. For a while he attended a veterinary curriculum in Skara with the taken name Euphrasén, from the plant Euphrasia stricta (or some other species of Euphrasia). This is the only case I know of where someone has borrowed a scientific name for last name. It is always the other way. Perhaps an easy way of getting oneself a patronym? He returned to and graduated from high school in 1780, immediately  signing on as sailor on a ship to China. Already in school he had become addicted to Botany and now on the trip to and from China he observed and collected fish. Very few of them it seems, five were described as new. Euphrasén wasn’t going to litter ichthyological nominospace.

Back home in 1783 he sold or handed over his catch to a wealthy merchant, Clas Alströmer in Gothenburg, who had a natural history cabinet. From now on Alströmer and Euphrasén interacted in various ways. Alströmer employed Euphrasén to curate his collections and eventually, when his finances fell low, move them to Gåsevadholm Castle in Halland. In 1787 Alströmer obtained support from the Royal Swedish Academy of Sciences for a trip to the Swedish West Indies, the island of St. Barthélemy, where Euphrasén made collections, mostly plants. Upon his return Euphrasén marrried to Maria Greta Hallberg and they had a son in 1793, but it seems Euphrasén  left Gothenburg and his family for good in the spring of 1794, after the passing of Alströmer. He moved to Stockholm where he worked in the Academy as some kind of assistant to Anders Sparrman. His manuscript about St. Barthélemy was somehow turned down by the Academy in 1792 following Sparrman’s review, but eventually it came out with Academy support in 1795. Interesting about this St. Barts thing relates to the fish. He had bought two specimens of a strange kind of cod in the harbour of Gothenburg in 1787 but they deteriorated on the way to St. Barts and were discarded. Imagine: collects a new species in Sweden and takes the specimens along to St. Barts, just to lose them to putrefaction, … well, well. Upon return it took some time to find a new one, and only  in 1793 one came into his hands. He described it as Gadus lubb, and quite in vain as it is a synonym of Brosme brosme (Ascanius, 1772).

Aetobatis narinari from Euphrasén 1790

Raja narinari = Aetobatis narinari, described from the Swedish West Indies. Drawing from Euphrasén, 1790, tail not shown.

At some point Euphrasén got himself working on a manuscript about Bohuslän’s fishes. As we all know, that’s all the Swedish marine fauna, and what is beyond that is not much, so at some later point he decided on and completed a Swedish Ichthyology, covering all Swedish fish species. In the late 1700s a national ichthyology was quite something innovative. The Academy, however, apparently refused to print it.  The manuscript, describing 106 species of fishes, is preserved in the library of Lund University. Euphrasén died in December 1796, of hernia. Poor, misunderstood, in conflict with colleagues, writer of masterpieces. There is no portrait.

There is of course a lot more to this biography, for which Gudrun Nyberg’s illustrated article better be consulted. Aside from calling attention to an earlier, relatively unnoticed colleague of mine (the Academy’s natural history collection became the Swedish Museum of Natural History where I work as a curator), I just wish to expose here some aspects of ichthyological concern.

Plants from the St. Barthélemy expedition were bought by Carl Peter Thunberg for the Uppsala University (Wikström 1825), displaying 113 objects online. Others are still in existence in the Botany department of the Swedish Museum of Natural History. They have 106 online  items with Euphrasén as collector. Unfortunately, the fishes seem to be gone altogether. The Swedish Museum of Natural History has specimens from one or more of the many Alströmer and the Academy, but nothing definitely from Euphrasén. Jonas Alströmer, father of Clas, was also a collector of natural history objects, and some part of his collection has found its way at least to the Museum of Evolution in Uppsala, but it still remains to be investigated what happened to the collections of Clas, and those of Euphrasén. The type of Gadus lubb was deposited in the Swedish Museum of Natural History, but apparently is no longer present there.

Interestingly, all of Euphrasén’s fish works are available online in one or another form. The St. Barthélemy treatise is published online by the Biodiversity Heritage Library. The Royal Swedish Academy of Sciences are publishing their Transactions online, and they include the four fish papers by Euphrasén. Well, they are all in Swedish, an older form which is not covered by Google Translate, but at least you can admire the elegant woodcuts. Obviously not much was needed those days to get a fish description done. The mystery remains, however: How come Euphrasén, travelling to the two extremes of the world, Asia and America, with all the world’s unknown tropical fish fauna within reach, obviously didn’t make more discoveries? He even failed with two out of three Swedish species, Gadus lubb (Bromse brosme ) and  Gobius ruuthensparri (=Gobiusculus flavescens). Why wasn’t his Swedish Ichthyology published? What makes people become ichthyologists?

The first publication, Trangrums-Acten (” The fish oil sediment document”),  from 1784 happens to be an environmental impact assessment study, maybe the first scientific of its kind in Sweden. At the time, herring was abundant and the production of fish oil boomed along the northern part of the Swedish West Coast. The oil was produced by fermentation and boiling in many hundreds of seaside factories. It was used for just about everything and it made Clas Alströmer and others rich. Regrettably, there was considerable waste of herring liberated from their oil. (The firs major oil sanitation operation in the world?) Waste products were dumped in the sea next to each factory, apparently producing local deoxygenation in addition to enrichening the air with the smell of millions and millions of rotten herring. The Stockholm based central government introduced a number of restrictions to reduce expected habitat detoriation (and curtail the increased wealth and political influence of the west coast companies?). That upset the oil companies, who responded with arguments in Trangrums-Acten. It resulted in the compromise solution to construct shorenear ponds to contain the smelly offal. Clas Alströmer was active in the investigations, but most of the work seems to have resulted from the coordination by Johan Lorenz Rutensparre (1752-1828), actually a naval military, but one of Sweden’s first environmental economists in his spare time.  At a field excursion in 1783, Euphrasén obviously found specimens of a new species, of which  Gobius ruuthensparri was described first in Trangrums-Acten, , but without name.

Bengt Andersson Euphrasén’s bibliography

Note on online content:  Most of he Academy Transaction papers are provided by the Royal Academy of Sciences Center for the History of Science. The German translations of Academy Transactions are provided by the University of Göttingen only up to 1788.

Euphrasén published as Bengt And. Euphrasén; where And. is short for Andersson, his original last name, but it is usually believed to be a first name (Anders). Indeed, in the 1786 paper his name is printed Bengt Anders Euphrasén, but that could be an editorial or printer’s decision. At the time children would automatically have the last name formed from the first name of their father (Euphrasén’s father was named Anders), but to this could be added something more distinctive, so that a double last name was common, as in today’s Latin America, Spain and Portugal. Not to complicate matters further, he is cited as Euphrasén, B.A. below, as people usually do. [It should be Andersson Euphrasén, B.]

Prickly manes, and a motor in the idle of their backs

Book cover of Poseidons steedYES – a book about seahorses!  Poseidon’s Steed, a strange breed of book by the way. Author Helen Scales, appearing in cork screw curl and soft smile on the non-optional author portrait,  a Cambridge doctor with a career in conservation, public outreach and coral reef fish studies, has summed up  a personal, life-long obsession with sea horses.

What I loved with Lady with a spear, the dedication to collecting and preserving fish for scientific study, does not charm this text, written by a diver and marine ecologist, but it has other qualities. To some extent collecting has to be excused here because there are already so many people catching seahorses that the whole subfamily Hippocampinae seems to be about completely pulverized into useless pharmaceuticals. And they are so cute, especially those pregnant males hanging around with  prehensile tails grasped around seaweed. It is probably easy to fall in love with seahorses, and Helen Scales has found every adjective to paint their virtues, beauty and mystery. For this is not just a fish book, it is a natural history and cultural history. After a little while of reading I lower my defense against the dangerously lurking anthropomorphisms and start to enjoy seahorse stories going back to Ancient Mediterranean civilizations and the story of Shennong and the birth of Chinese medicine, and forward to the pointless exploitation of seahorses for Chinese medicine and technical aspects of captive breeding. There is even a chapter about the early history of the aquarium hobby in mid-19th Century England that I found very warming. For those technically oriented there are lists of seahorse species, a map of seahorse distribution, numerous pages of references and a substantial bibliography. The shameless ideas about species discrimination is the only dreary part: “Imagine you are holding a length of silk ribbon dyed in all the colors of the rainbow; each color represents a different species. But where exactly does one species end and another begin?” The concept of a continuum of species and endless intermediates perpetuated by many ecologists, seems inexterminable.

Chinese medicinal seahorses

Dried seahorses intended for medicinal use

Seahorses are lovely. They are cute, and strange of form. There are a little more than 50 species, the most rectly described Hippocampus paradoxus Foster & Gomon, 2010. Being nothing but curly pipefish, male broods the eggs and alevins, and does so in a pouch fitted to its belly. Freeswimming progeny is left for the currents, which may be hard upon such cute minihorses. However, once coupled a male and female stay a pair for all their life, and that provides the cream topping for the anthropomorphy of the creature. Indeed, pipefish including seahorses, provide important data for studying parental investment. In fish, brood care is commonly left to males (cichlids are an exception), but the brood-care is rarely much more than looking big and fierceful and staying atop of the offspring. Pipefish males stick out as truly live-bearing.

Contemplating seahorses it is easy to forget that it is humans that are like the other animals, and not cutie animals like seahorses and dogs that are like humans. All our behaviour comes from somewhere and has a direct evolutionary line back to an amoeba of sorts. The way we are has probably very little to do with our complex reflective brain that is constantly battered in abstract synaptical storms known as intellectual activity, along with empathy, reflection and self-awareness. Looking around us, it is obvious that human intellect is not favored at all in the animal community. A seahorse is completely unknowing, it does not think, reason, reflect or otherwise interact contemplatively upon its surroundings or its own senses. Although intelligence is not only a function of brain size, brain size in fish is indeed  indicative of abilities of thinking. FishBase has a database of brain size in fish, and you can use FishBase to plot brain weight vs. body weight. The brain of a 6 g seahorse weighs 12 mg (compare an average 1.5 kg in humans), and this is small even for a fish. It does not know it is a loving father and a devote husband, or a divine steed. If it were 12 feet tall it would probably just suck you in using its high-speed vacuum cleaner hose snout. That is not going to happen. Seahorses are forever cute. All this “human” behaviour in pipefish goes on with 12 mg of brain.  With that, what doesn’t a seahorse male brain indicate that one could minimally expect from a father and husband …?

Footnotes:

Seahorses are a genus, Hippocampus, of pipefishes (family Syngnathidae) , belonging to the order Gasterosteiformes (sticklebacks, tube snouts, and the like). FishBase has information about 54 species of Hippocampus (as of 1 February 2010).

Poseidon’s Steed is published by Gotham Books and available from all online book dealers. The paperback has 261 pages and a block of black and white photos. “This is one charming book about one charming fish.” (Quote from the back cover).

The heading of this commentary is from a quote in Poseidon’s Steed, taken from Daily Telegraph, London, 1869.

Day 1, 2011

As the snow whirls around and the cold fills up the atmosphere, the new year brings a welcome day off to be taken care of. Dough is rising and breakfast bread will be served in an hour or so. Family is sleeping, stoned by the unusual late hours to sit through the paradox of a year and decade shift without anything really happening. Only computers worldwide automatically shifting display date, steadfast from Australia westwards. It takes 24 hours to shift from one day to another, or does it?

The past autumn proved hectic to the limit of sustainability and blogging plummeted, so there is something to be caught up on.  Most of last year wasn’t in the plus column, however, so there is a lot to be expected from this one. The highlights of the past twelve months that come to mind spontaneously were:

The FishBase Symposium 2010 in Stockholm, October 18, featuring a fantastic series of talks by highly successful, competent and enthusiastic personality scientists covering all of what it takes to be a fish systematist, not least the field work and the need for specimens, not only tissue samples to do systematics, Melanie Stiassny, Maurice Kottelat, Tan Heok Hui, Richard Pyle, Jörg Freyhof, Anthony Gill, moderated by one more star, Ralf Britz. The audicence enjoyed the show tremendeously, and so did I. There is a report to download, most of it in Swedish, but there is always Google Translate.

Te Yu Liao’s PhD dissertation defence with Paul Skelton as opponent, 18 November. Te Yu has been with us at NRM since 2006 working on a revision of Rasbora and similar fishes. It has resulted in several phylogenetic studies, and several morepapers, altogether seven publications,  included in the dissertation (A phylogenetic analysis of the rasborins (Cyprinidae: Danioninae: Rasborini)) but still to be published. These papers provide a new framework for danionine systematics and are based on both morphology and molecules. Some of the papers are:

  • Fang, F., M. Norén, T.Y. Liao, M. Källersjö & S.O. Kullander. 2009. Molecular phylogenetic interrelationships of the South Asian cyprinid genera Danio, Devario and Microrasbora (Teleostei, Cyprinidae, Danioninae). Zoologica Scripta, 38: 237-256.
  • Liao, T.Y., S.O. Kullander & F. Fang. 2010. Phylogenetic analysis of the genus Rasbora (Teleostei: Cyprinidae). Zoologica Scripta, 39:155-176.
  • Pramod, P.K., F. Fang, K. Rema Devi, T.-Y. Liao, T.J. Indra, K.S. Jameela Beevi & S.O. Kullander. 2010. Betadevario ramachandrani, a new danionine genus and species from the Western Ghats of India (Teleostei: Cyprinidae: Danioninae). Zootaxa, 2519: 31-47.

Peter Cottle’s book about danios (Danios and Devarios) came out in December, and made a great holiday gift. The title of the foreword (which I wrote …) summarises the opus: Passion. I will get back to this book and others, but suspecting the edition may be somewhat limited, I would recommend you to get your copy now …

What is up now:

There will be more danionine papers, several already in press

A long series of cichlid papers are in an advanced state, both on African and South American cichlids

FishBase will organise three meetings this year: the annual FishBase Minisymposium with the FishBase Consortium, the annual Swedish FishBase symposium, and triannual Artedi Lectures

The first volume about fish in The Encyclopedia of the Swedish Flora and Fauna series will be published in May or so. This volume covers all species of chordates occurring in Sweden from cephalochordates to chondrichthyans, authored by me, Thomas Stach (tunicates) and Henning Blom (introductions to chordates and vertebrates). The illustrations, however, may be the major reason to look forward to this book. They are all new, and all the Swedish fishes are superbly illustrated from scratch by Linda Nyman and Karl Jilg (I haven’t seen the tunicate illustrations).

And I will go to Iceland. All my life I strived to go south, to warmth, but my former student, Georg Friðriksson, who is now an ichthyologist with the Náttúruminjasafn Íslands, has assured me that Iceland is not covered with ice and snow in the summer (or has he? May have to ask again). They have fantastic fish, all kinds of ecophenotypes of char, but also sticklebacks.

As you can see, 2011 looks all bright, new, and worth living.

In the media: WWF and Danio tinwini

The little fish hit the headlines today, in WWF‘s press release on their report on species described from South East Asia in 2009. Although the cover honours a radically crimson dracula fish (Danionella dracula), page 11 is devoted to Danio tinwini, subject of a longer treatise in this irregular blog.

Of course there are other rare or spectacular things in that report which is well worth downloading. WWF has counted 145 new species as described from what they call the Greater Mekong area. Twenty-six species are fish, four of them from my lab:

  • Danio aesculapii Kullander & Fang

Of course, it is nice of WWF to highlight the species diversity in the region, and there may very well be another 26 species described every year, on and on. It is also welcome that WWF and others are putting funds and energy into conservation efforts of critical areas or whole ecosystems. This work is badly needed; every living thing in the tropics is at risk, and a greater risk every day. It is unfortunate, however, that practically all those discoveries are done with a minimum of funding only, or just out of devotion.  Taxonomy and discovery is underfunded. Where is the money for the discovery, description, and mapping of all the unknown biodiversity?

On October 18, FishBase Sweden organises its annual Symposium. This time the theme is discovery. The importance of exploring new areas, and discovering new species and analysing the evolutionary history of those life forms.  The programme is available from the FishBase Sweden website.

Freud as an ichthyologist

Life is full of surTitle of Freud paper on Lampreyprises, strange revelations, or maybe just shortcut or short memory. Tidying up my office the other day, this tractate caught hold of my curious eye.  A not so short dissertation of the spinal ganglia and the spinal cord in the lamprey, authored by the medical student Sigm. Freud [Sigmund Freud], and published in the Proceedings of the royal Academy of Sciences in Vienna, Austria in 1878. Same journal which carried so many of the more famous ichthyologist Franz Steindachner.

Wow, psychoanalysis started with the dissection of the central nervous system of one of the most primitive fishes! Only hagfish is lower on the tree, beyond that there are only invertebrates. Or maybe not. Whereas Freud’s ichthyological career passed relatively unnoticed among ichthyologists, he is well known as a neuroanatomist among the physiologists (neurophysiologists, to be precise). He started his career with eel, spending four weeks trying to find male eel in Trieste, Italy. Up till then testes had not been found in European eel. His studies on lampreys resulted in two papers and one methodological note; the eel study in one paper, somewhat inconclusive, but later confirmed to have located the testes. Freud apparently preferred neuroanatomy and remained with this subject for years.

Is that a cigar, or ...

My recollection of Freudian psychoanalysis (in which fish are scarce) is the more frequently told interpretation of snakes in dreams as the [fear of] penises. The myriad of dream analysis scam sites on the web nodd affirmatively. But we all know Freud must have been inspired by the eels and lampreys more than snakes into developing his untestable dream explanations. And people rarely dream about eels and even less about lampreys. They rather dream of snakes, although there were never any snakes in the dreams I remember (but plenty of fish). So, on the simple side of having it, psychoanalysis is all about slithering fish.

I doubt there is any 20th Century ichthyologist more famous than Sigmund Freud. Regrettably for him, he is not in boldface in the annals of fish science. For what I can find there are more batmani or [led] zeppelini than freudi among fish, so not even more famous than a comics character or a guitar hero (not a single freudi, in fact). I am not sure this entry does anything to help improve on the recognition and fame of Sigmund Freud, but I am sure many will be interested to know about this connection between the eel and the mind.

Artedi lives!

Some of you may have observed the excellent movie by Elizabeth Watson for the Artedi Symposium in 2005. It misses the Artedi part, however. Now, Elizabeth kindly made available also this critical drama. Petrus Artedi working at the waterfront, barefoot, quill pen in hand and on the whole rather charming and primitive. Starring Jonathan Ready in 18th century outfit worthy of any ichthyological master.

Swedish as we are, and I grew up fishing in Örnsköldsvik not many kilometers from Artedi’s birthplace in Anundsjö (many years later, though, he moved to Nordmaling before I arrived), we cannot simply forget the man who discovered systematics, the genus concept, and the descriptive method of Ichthyology, although everyone else seems willing to do so. The discussion goes on and on, did Linnaeus simply plagiarize Artedi? Ted Pietsch, American but from Washington state which is almost as cold as Sweden, has a new book out on the interaction between Linnaeus and Artedi, which will be given some lines here eventually. The Royal Skyttean Society, one of Sweden’s 18 noble academies, just published the proceedings of their Artedi Symposium in 2005, and in 2011 it is again time for the third Artedi lectures event.

To those who haven’t heard of Artedi, but are going to watch Elizabeth’s film: Petrus Artedi, born 1705, in Anundsjö, north Sweden, studied with Linnaeus in Uppsala, sharing interest in natural history and classifications. Both then travelled to the Netherlands to study and graduate. In 1735, Artedi drowned in a canal in Amsterdam. Linnaeus took care of his manuscripts and published them in 1738 as Ichthyologia, sive Opera omnia de Piscibus, which was a highly innovative and complete treatise of ichthyology. The fish taxonomy in it found its way into Systema Naturae. The film was shot in September 2005 on the bank of Edsviken Bay, on the premises of the Ulriksdal Palace, the first building dating to 1643, home to queens and kings, among them Adolf Fredrik and  Lovisa Ulrika (1720-1782), whose natural history collections were studied by Linnaeus. It is now the seat of Swedish WWF. For what we know, Artedi was never there, but Linnaeus was (me too), and you can feel the 1700s in the bare branches of the trees, the water’s reflections, and Artedi’s frozen feet.

A very strange danio

Every well informed freshwater ichthyologist is familiar with petfrd.com forum.  Petfrd does not easily translate to Singapore Cichlid Community, which seems to be the patron of the site, but I have no clue to what petfrd could mean. The forum has several sections, and postings are enthusiastic and often with beautiful images of habitats or fresh collected fish contributed by local aquarists from all over southern Asia (and others, sure) . Ng Heok Hee moderates a section about scientific literature and usually is abreast of locating new papers about cichlids or Asian fishes. So, here is the secret about staying informed: daily visits to petfrd.com!

In January 2008, information and photos were posted of  what looked like a danio but sufficiently different not to be ignored as ‘one more…’. ‘Beta’, with a sad smiley reported that his fish were in the freezer. Fang immediately got in contact with ‘Beta’, whose name is actually Beta Mahatvaraj, enthusiastic Indian aquarist. His five frozen fish were preserved in ethanol and formalin and shipped to us. They weren’t really fresh, and the colour somewhat faded, but still all anatomy and DNA could be extracted from hem. Fang started writing up a description and gave it a manuscript name, ‘Betadevario longibarbis’.

It wasn’t a Danio as some of the first reports had it. It was more like a Devario, with those longitudinal depressions above each eye filled with sensory organs, characterizing Devario and Chela. But still not looking like a Devario, above all because of the long barbels, but also with regard to the coloration, which is unique among danios, with a light band along the middle of the side, and dark abdominal sides. Devario typically have very short barbels or they are missing completely, whereas most Danio have long barbels.

Actually, Devario is a speciose genus with more than 50 species, many still undescribed, and there is considerable variation in shape and colour pattern among them. They never have long barbels, though.

Since everything takes long time for us (the Cichla revision published 2006 took 17 years, and other papers not published were written in the 1980s, to give you a hint), it wasn’t unexpected to learn in 2009 that an Indian team was also working with the same species, and also with very few specimens. It took till December 2009 before we established contact and things were arranged for a collaborative effort to get the fish described. In the meantime much more material had become available, and indeed there were already numerous presentations of the fish on the web, e.g., in PFK  and in several Indian news sites.  Collaborating meant we could provide a fairly complete review of the new species with habitat data and image, live colour photo, and molecular and morphological phylogenetic analysis, better than individual papers would have been.  Betadevario got the species epithet ramachandrani for A. Ramachandran. Our molecular and morphological analyses differ with regard to its placement in the phylogenetic tree, but it is certainly a very basal taxon among Devario like danios, and we have more confidence in the molecular data which places it as sister group to other Devario.

Why not make it a Devario then? A good question for any genus, and will never have a good answer for all who come up with it. In this case we reasoned that the molecular analysis provided better clarity. The morphological dataset was good for distinguishing Devario and Danio, but not for resolving relationships within Devario. We have to work a lot more on that. And we are doing it, with both morphology and molecules. Betadevario presents a unique colour pattern and long barbels to distinguish it from all Devario (including Inlecypris),  providing a morphological justification for the genus.

The largest specimens measured about 60 mm. There are no characters to distinguish males and females, except the tubercles on the pectoral fin in males, a secondary sex indicator shared with most Danio and Devario. Information on live colours are not in concert. The live fish on Beta Mahatvaraj’s image are golden and brown/blackish, whereas the illustration by P.K. Pramod shows a a fish with a blue stripe along the side and lemon yellow fins. It will be interesting to see Betadevario alive sometime. It does not look like it will be a big aquarium fish, but who can say. It is so far known only from a small mountain stream in the Western Ghats, with relatively cool water, and may be expected to be sensitive to transportation.

Betadevario ramachandrani is known only from a very small area in the Western Ghats, the mountain range along the western coast of India, where it lives in fast running clear waters in the forest.

You don’t need a longer story here. The full description of Betadevario ramachandrani with habitat image, trees, and other details is available free to download from the Zootaxa website.

In Memoriam: Alf Johnels

My former superviser, Alf G. Johnels, passed away on 24 May, 2010, at age 93.

Alf has a long and interesting professional record, crowned by his professorship at the Department of Vertebrate Zoology at the Swedish Museum of Natural History (1958-1982), and his presidency of the Royal Swedish Academy 1981-1983. He was also a key person in the discovery of mercury poisoning in Sweden in the 1960s, which laid the foundation for advanced ecotoxicology. By analyzing bird feathers in museum collections, Alf and collaborators could show that mercury poisoning in birds coincided with the introduction of methyl mercury as a pesticide. This led to the establishment of a biobank at the Swedish Museum of Natural History in which samples are preserved under sterile conditions, and which will enable the study of time series of toxic substances in the environment.

More important for us, however, is Alf’s ichthyological career. It started in early childhood, and led him to become a fisheries biologist first — to be certain of a fallback — but he also studied lamprey anatomy at the Zootomical Institute (now Department of Zoology) of the Stockholm University where he obtained his PhD in 1948. Those were the days when anatomy was important, and every biologist knew the name of every cell and every structure inside an animal, and the Zootomical Institute had several world renowned researchers of the kind. Alf and others in Stockholm were very much interested in the early development of fishes, as a way to understand the formation of organs in adult fish. The one major field trip Alf made had as objective to sample ontogenetic series of various “primitive” fishes, principally lungfish and bichirs.

Together with Ragnar Olsson and Björn Afzelius he travelled to the Gambia in 1950, staying there from May till November. This was long before the Gambia became a tourist spot. The trio settled in Bansang, in the middle of a swampy area full of lungfish and bichirs. They searched out nests of these species, and took out and preserved some eggs, later larvae, about every day. They also collected other fish, of course, and together with the material from an earlier expedition in 1932, the University built up a significant collection of Gambian fishes. The collection is now in the Swedish Museum of Natural History. The team also took back quite a number of living fishes, and some of the smaller species entered the aquarium trade in Stockholm for a while.

In 1954 Alf produced a descriptive catalog of the collections made at Bansang, in which he described three new species, Pellonula afzeliusi, Syngnathus olssoni, and Barbus svenssoni. Unfortunately, they are all synonyms. Chrysichthys johnelsi, named after himself by Daget, is however still a valid species. He also produced a small paper about the scales of Gambian fishes, showing that in the low water/dry period, the scales are eroded at the margin.

After retirement, Alf had time to devote to his main passion, salmon fishing, going fishing ever so often to Norway and returning empty-handed. One of his last works was a descriptive catalog of the salmon rivers of southern Norway. Nevertheless, he kept coming to the museum every day till just a few years ago when his health conditions became preventive.

Alf was a very special person, always neatly dressed, always a bowtie on, always well articulated on any subject of science. His mind wasn’t as conventional as his dress, and he described himself as more of an engineer than a scientist. It is well remembered when he helped us fishing stone loaches — dressed in suit, and using his umbrella as fishing gear.
