They will be online in a few days as spare time allows. Also, thank you very much for your supportive comments. Chris Glasby's online monograph distribution via PDF files was very popular. We think this is likely to become a more common practice, although doubtless not all publishers will be as accommodating as regards copyright. Even if you are not a nereid fan you might find it interesting to have a quick look at the pics on the introduction page: http://biodiversity.uno.edu/~worms/docs/namanereid.html If anyone was unable to work out how to access or save the files please let us know. Finally, congratulations to Elin Sigvaldadottir & her team for a successful launch this week of the Iceland 7th Conference web site and first notice. I'm hoping to get there too this time. It couldn't be much further away from here though!

Our apologies for cross posting. Monday, 12 July 1999 Dear Annelidans / Marbio / Taxacomers: I was recently contacted by Wilma Blom and Hugh Grenfell, New Zealand, regarding the following mass occurrences; we are preparing a paper on this and would appreciate additional informaton: In the past few years, first noticed in 1997, enormous numbers of tubes of a mainly small epifaunal Chaetopterus sp. (identity not yet certain), have washed up along some northern New Zealand beaches. The rows of washed-up tubes along the beaches can extend for hundreds of metres, and all of those examined to date have been empty. Recent investigations with SCUBA, however, have shown significant populations of live individuals in the nearby nearshore areas at about 10-15 m depth. Other searches intertidally and with snorkel subtidally have revealed a) very dense populations occurring intertidally on rock platforms in Corallina algae turf with a thin veneer of sediment; or b) under boulders subtidally. There does not appear to be anything in the literature about similar washups of Chaetopterus tubes from other areas. We are preparing a paper describing these mass occurrences, together with information on the live material and notes on the species, and would like to incorporate observations from other areas if such exist. Any personal observations or references to literature or notes on this topic, including in gray literature, would therefore be greatly appreciated. For personal observations, please include sufficient data on habitat, worms and tubes that we have a chance of seeing which species might be involved. To date most Chaetopterus species have been (incorrectly) reported as C. variopedatus, which is not cosmopolitan as earlier believed by many workers. Approximate size of worms, whether the tubes are stiff or collapsible in the middle (most tubes are stiff near the openings), and whether the worms are infaunal or epifaunal, plus locality, will help limit the possibilities. All help will of course be fully acknowledged in the paper. Please send information directly to Mary E. Petersen (mepetersen@zmuc.ku.dk). Thanks in advance for any help.

[Please direct replies to the enquirer - Moderator] I am a lightly-trained invert zoology buff, and a marine aquarium hobbyist. I have an annelid that I am trying to evaluate as marginally economically important, because it seems to appear with frequency in the "reef aquarium" trade. One of the marine substrates reef aquarists may collect "live rock", which is usually synonymous with wild-collected dead coral rubble (although many live specimens are available too) from a reef. As a substrate in an aquarium, live rock is thought to provide capacity for anaerobic digestion, imporatnt in maintaining low nutrient load in the reef tank. Live rock has the extended benefits of usually introducing, to the captive reef, a small ecosystem replete with a host of marine invertebrates like annelids, amphipoda, and other zoo- and phytoplankton. I have singled out a marine polychaete whose presence in my tank possibly goes back to the installation of live rock from Micronesia. This organism is observed widely in the hobby, if aquarium newsgroup posts are any indication, and is often identified, without benefit of analysis, as a bristleworm, which is in turn often assumed to be either a predator on bivalvia and other prized specimens, or a fire worm, which would be a genuine cause for concern (it gives painful stings that may require hospitalization) if it were a correct identification but is usually not. My interest in this annelid is the former: I want to know if it is a predator. It flourishes in some tanks, occupying tiny holes in the coral substrate, and stretching out after dark, even going peripatetic in search of food. Many times I have found them in close association with specimens that are then observed to be moribund. Whether this is a result of polychaete-induced stress (either feeding on the stressed organism, or simply generating locally high levels of waste), or whether the polychaetes are being terribly good at cleaning up dead/dying specimens isn't clear to me. The aquarium trade loudly insists that the worms are no predators! At any rate, the technology doesn't exist to rid a reef tank of the denizens, so onehopes they are essentially benign, only facultative carnivores if at all. On my web site I have posted a picture of a specimen which is inadequate but suggestive. Organism is ~ 2" long . I worked out some of the most diagnostic systematics, hope I've done something useful: 60 segments, first 10 anterior are pink incolor, gut begins where segments become dark in appearance in photo) Dorsal paraposium w/gills, many fine setae and one large seta. Ventral lateral parapodia w/many fine setae and one large seta. Prostomium rounded, slight indentation in center First 4 or 5 anterior segments have a longitudinal raised area (a ridge). 4 eyes (1 pr large eyes, one pr small eyes), arrayed along anterior lateral margins of the raised area. (darn, I did a second study that I can't lay my hands on now). I'll try and answer questions based on the study (if I find it) or a live a specimen. The most telling attribute, vis a vis the question of whether or not they prey on valuable tank specimens, seems most likely to be their feeding apparati. This worm has an evertable pharynx, but I cannot, with my Tasco 2X and very sharp dissecting tools, find any sign of hooks, teeth, or grabbers inside the pharynx. The inner surface of the pharynx is striated, evident when everted and cut longitudinally. So, hopefully the picture ( http://www.edword.com/annelid/Image073.jpg ) will trigger some recognition! I await your insights, thou most collegial scientists and classifiers.

(1998) recently published a critique of my phylogenetic analysis of annelid, echiurid, and siboglinid (= Pogonophora and Vestimentifera (see McHugh, 1997; Rouse and Fauchald, 1997)) relationships based on the nuclear coding gene, elongation factor-1a (EF-1a) (McHugh, 1997). Unfortunately, Siddall et al. (1998) made several misleading and obfuscatory statements about the EF-1a analysis, and omitted information that supports the EF-1a results that I presented. In addition, they stated that they could not reproduce the results of McHugh (1997), which may give readers the mistaken impression of discordance between the methods I applied and the results I presented. Here, to clarify matters and to avoid the propagation of incorrect information, I directly address specific quotes (in italics) from Siddall et al.

I am sure, others will answer too, but here's what I know: For a work on modelling the larval dispersal of deep-sea hydrothermal-vent alvinellid polychaetes (Chevaldonne et al. 1997; see ref below), we searched what was known about the life span of polychaete pelagic larvae, mainly focusing on Terebellomorph polychaetes. Here are excerpts from the discussion: "The longest planktonic period recorded for the larvae of Ampharetidae, a polychaete family related to Alvinellidae, is 3-5 days (Nyholm 1951). (...) Ampharetid species are reported to have an entire larval life (i.e. planktonic and non-planktonic) lasting 2-5 weeks (Hutchings 1973; Zottoli 1974). (...) However, Thorson (1961) reported that polychaetes are among the invertebrates that can delay the most their metamorphosis, and cites a maximum pelagic larval life of 18 weeks for polychaetes. (...) In addition, some terebellids are known to metamorphose and subsequently feed as juveniles in the plankton while still drifting (Levin and Greenblatt 1981)." Hope this helps. As for the alvinellids, the question is still unresolved for sure.

Please LOOK at the 'To' box. Is it going to ANNELIDA or the person? Where did you want it to go? In general I have the impression that messages tend to be kept private that would be interesting & rewarding to share. And questioners - if you do get a stack of good private replies you should consider posting a summary (condensed & usually omitting people names). It can be frustrating for the rest of us to see an interesting question and never know the answer, or the other opinions. I would like ANNELIDA to be used more as _discussion_ list, and that will not happen if you don't contribute back to the list. Yes, it is OK to try ANNELIDA as a means of getting other people to do reference work for you, but if it is a question that appears easily answered elsewhere then do not be disappointed when there are no replies.

Higher Level Relationships of Leeches (Annelida: Clitellata: Euhirudinea) based on Morphology and Gene Sequences.— Molecular Phylogenetics and Evolution, 12(3):350-359. (August issue). Abstract: "The evolutionary patterns of divergence of seven euhirudinean families were investigated by cladistic analysis of 33 euhirudinean species. Oligochaetes, Acanthobdella peledina, and branchiobdellidans were included as outgroup taxa. Cladistic analysis employed 1.8 kb of nuclear 18S ribosomal DNA and 651 bp of mitochondrial cytochrome c oxidase subunit I in addition to morphological data. The use of two molecular data sets, one nuclear gene and one mitochondrial gene, as well as morphological data combined historical information evolving under a variety of different constraints and therefore was less susceptible to the biases that could confound the use of only one type of data. Results suggest that the nuclear 18S rDNA gene yields a meaningful historical signal for determining higher level relationships. The more rapidly evolving CO-I gene was informative for recent or local areas of the evolutionary hypothesis, such as within-family relationships. Analyses combining all data from the three character sets yielded one most-parsimonious tree. Most of the higher taxa in recent leech systematics were well corroborated in the resulting topology. However, these results suggested paraphyly of the order Rhynchobdellida, which contradicts the presence of a proboscis as a synapomorphy. The medicinal leech family Hirudinidae was polyphyletic because Haemadipsidae and Haemopidae each have a hirudinid ancestor. In addition, all but one of the genera within the family Erpobdellidae must be either abandoned or renamed. Unusual findings included compelling evidence of historical plasticity in bloodfeeding behavior, having been lost at least four times in the course of euhirudinean evolution. Biogeographic patterns supported a New World origin for Arhynchobdellida." -- ANNELIDA LIST Discuss = = talk to all members Server = = un/subscribes Archives = http://www.bio.net:80/hypermail/ANNELIDA/ Resources = http://biodiversity.uno.edu/~worms/annelid.html -- From daemon Wed Jul 21 07:51:36 1999 Received: by net.bio.net (8.9.1a/8.9.1) id CAA22674; Wed, 21 Jul 1999 02:15:42 -0700 (PDT) Date: Wed, 21 Jul 1999 02:15:42 -0700 (PDT) Message-Id: <199907210915.CAA22674@net.bio.net> To: annelida@net.bio.net Reply-To: annelida@net.bio.net From: nwilson@zoology.uq.edu.au (Nerida Wilson) Subject: Poecilogony I was wondering if anyone had any neat examples of poecilogony that they could put me on to.

We are finding a local cosmopolism of spionids, syllids and onuphids, and are wondering on the occurrence of species not relying on planktonic larvae for dispersal, mainly onuphids (Aponuphis bilineata, Onuphis eremita) and a high number of syllid species. Only Bhaud & Duchene (1994) have given some evidence that swappings between benthopelagic and benthic development are common among polychaete fauna and may have taken place several times in the evolution of species to date. On evolutive grounds, he has argued that benthic development may have been possibly adopted by some polychaete populations faced with environmental constraints like massive loss of larvae by dispersal through water currents (Bhaud 1988). This condition is particularly dramatic in the sublitoral of oceanic islands, but the possibility that some dominant brooding species occurring in La Gomera (e.g. A. bilineata and most syllid species) have undergone such reproductive shifts is obviously only speculative. Besides, vicariant populations of Eupolymnia nebulosa from the Mediterranean and the North Atlantic have been found to use differing reproductive strategies in order to minimise larval loss (Bhaud & Duchene 1994), but further research needs to be taken to confirm if other polychaete species populations are plastic enough to resort to either benthopelagic or benthic development in function of the constraints of their habitat, oceanic islands standing as fairly appropriate environments to address this issue. Do you have any research evidence that those reproductive swappings have taken place in syllid and onuphid polychaete families? Ideas are very welcome indeed. Thanks.

Evidence for poecilogony in Pygospio elegans (Polychaeta : Spionidae).— Marine Ecology Progress Series, 178:121- 132. ABSTRACT: The spionid polychaete Pygospio elegans displays more than one developmental mode. Larvae may develop directly, ingesting nurse eggs while brooded in capsules within the parental tube, or they may hatch early to feed in the plankton before settling. Asexual reproduction by architomic fragmentation also occurs. Geographically separated populations of P, elegans often display different life histories. Such a variable life history within a single species may be interpreted either as evidence of sibling speciation or of reproductive flexibility (poecilogony). Four populations from the English Channel were found to demonstrate differing Life histories and were examined for morphological and genetic variability to determine whether P, elegans is in fact a cryptic species complex. Significant but minor inter-population polymorphisms were found in the distribution of branchiae and the extent of spoonlike hooded hooks. These externally polymorphic characters did not vary with relation to life history, and variation fell within the reported range for this species. Cellulose acetate electrophoresis was used to examine 10 allozyme loci, 5 of which were polymorphic. Overall, observed heterozygosity (H-o = 0.161) was lower than that expected under Hardy-Weinberg equilibrium (H-e = 0.228). Significant heterozygote deficiencies, detected at the Est* and Xdh* loci in all populations (except Xdh* at Ryde Sand, Isle of Wight, UK), are discussed. F-statistics were used to examine patterns of genetic structuring among both separate and pooled populations. F-ST values at all polymorphic loci indicated a significant level of genetic differentiation between populations, most probably related to isolation by geographic distance. No direct relationship between life history and genetic structure could be detected. Overall genetic identity among the 4 populations was high (I= 0.977 to 0.992). Overall, populations displaying larval brooding did not appear to be reproductively isolated from populations displaying a fully planktonic larval mode. Present data support the hypothesis that P. Elegans is poecilogonous. -- Geoff Read -- ANNELIDA LIST Discuss = = talk to all members Server = = un/subscribes Archives = http://www.bio.net:80/hypermail/ANNELIDA/ Resources = http://biodiversity.uno.edu/~worms/annelid.html -- From daemon Thu Jul 22 15:08:31 1999 Received: by net.bio.net (8.9.1a/8.9.1) id PAA01983; Thu, 22 Jul 1999 15:08:31 -0700 (PDT) Date: Thu, 22 Jul 1999 15:08:31 -0700 (PDT) Message-Id: <199907222208.PAA01983@net.bio.net> To: annelida@net.bio.net Reply-To: annelida@net.bio.net From: Torin Morgan Subject: Re: Poecilogony Dear all, With Nerida's and Salva's threads running at the moment it's good to see all this interest in poecilogony. The question of flexible life histories is clearly very important to our understanding of speciation in groups like the spionids. Geoff quotes the abstract to my recent paper on Pygospio (I've still some reprints left!) and I hope this contributes to the debate, but there's plenty of work left to do on this species. I'm developing new molecular markers to use on Pygospio, and I'd love to compare lots of populations with differing life histories. To this end, I'd be very interested to hear about other Pygospio populations out there. best wishes Torin Morgan ---------------------- Dr Torin Morgan School of Ocean and Earth Sciences Southampton Oceanography Centre European Way Southampton SO14 3ZH office tel: +44 (0)1703 596270 lab tel: +44 (0)1703 596502 mobile tel: 0976 924159 email: torin@soton.ac.uk -- ANNELIDA LIST Discuss = = talk to all members Server = = un/subscribes Archives = http://www.bio.net:80/hypermail/ANNELIDA/ Resources = http://biodiversity.uno.edu/~worms/annelid.html -- From daemon Thu Jul 22 15:08:30 1999 Received: by net.bio.net (8.9.1a/8.9.1) id PAA01982; Thu, 22 Jul 1999 15:08:30 -0700 (PDT) Date: Thu, 22 Jul 1999 15:08:30 -0700 (PDT) Message-Id: <199907222208.PAA01982@net.bio.net> To: annelida@net.bio.net From: "James A.

Arnofksy. In Press. Reproduction and larval development of the spioniform Polychaeta with application to systematics and phylogeny. Hydrobiologia. This paper is part of the proceedings of a symposium on the Reproductive and Developmental Strategies of Annelids that was hosted by Wilfried Westheide and Adriaan Dorresteijn in Osnabruck, Germany in September 1997. Proofs of the various papers have been returned and we understand that publication by Kluwer will occur later this year. Largely as a result of discussions on poecilogony that arose during the symposium, the section on the subject of poecilogony was expanded in our paper. According to the literature reviewed, the following spionids may be considered to exhibit poecilogony: Boccardia proboscidea, Dipolydora quadrilobata, Pygospio elegans, Pseudopolydora kempi, Spio decoratus, Spio martinensis, Spio setosa, and Streblospio benedicti. However, in my opinion, it is possible that the different populations of D. quadrilobata, P. kempi, and the three Spios exhibiting differing modes of reproduction might represent separate sibling species once appropriate studies are conducted. Also note that there are numerous records of Polydora, Boccardia, etc. where nurse eggs have been reported as present or absent according to timing of collection and locality. All of these records are summarized in the paper but few have been documented or studied further. I think the subject is a fertile one for research.

He sampled populations on the east coast, west coast, and Gulf of Mexico including both species of Streblospio (benedicti and gynobranchiata). Gene sequences of the mitochondrial cytochrome oxidase subunit 1 (CO1) were determined for each population along with morphological and reproductive data. The manuscript from this work will be submitted later this summer and the Master's Thesis should be on file in the library at the University of South Florida, Tampa. I don't want to spoil the fun of the publication, but the bottom line is that the CO1 sequences have proven useful in detecting recent speciation events in spionids. The division of Streblospio into two North American species appears to be substantiated by the molecular data (fortunately for me!). The North Carolina populations of Streblospio that exhibit different modes of larval development as described by Lisa Levin appear to be the same species based upon CO1 sequences. We are collecting similar information on Polydora cornuta (ligni) this summer and hope to have a story to tell by next summer's Evolution meeting. Stay tuned for further announcements.

Do we have a chance to get an up-to-date list of our beloved beasts in 2000? Species 2000 basically is a consortium global species databases (GDSs) of certain taxa. It plans to make available a 'Common Access System' to these databases. At present there is only a proof-of-concept search engine available on its web site (www.sp2000.org), where you can also find other details. The Unesco-IOC Register of Marine Organisms (URMO), which I am editing, is one of the members of Species 2000. This register is under construction and until now only a small portion of it is available on a web site. I hope this is going to change soon, when a new data base system will be available. However, I regret that "our beloved beasts" are still not well represented. Certain small groups are there already, e.g. sipunculids, echiurids, priapulids. The marine hirudineans are also managable, but it will be a major effort to make an up-to-date list of polychaetes. Some families will be easy and several colleagues gave contributions but there are no experts for most families. I think we will not get much further than a highly preliminary checklist. Obviously only part of the URMO databases can be used as GDS for Species 2000. Several groups such as vertebrates, oligochaetes and hirudineans are largely terrestrial or limnic and consequently not complete in URMO. In some cases such as cnidarians and gastrotrichs I did include the limnic species so they can be used as Species 2000 GDS. For several groups URMO is also being used for the European list Gerard Bellan was refering to, which is particularly easy in those cases where geographical details are available. Anyway, we try to avoid duplication of efforts whenever we can.

I'd be rather surprised if Vasily is unaware there is such a project underway for many years. It's widely known (it was for instance the subject of a poster at the 1992 conference). It's up to the workers concerned whether they wish to comment at this moment. Regardless of how that's progressing, and regardless of whatever regional lists appear (or have appeared) for Species 2000 and many other purposes, there is nothing to stop other specialists from planning to release to the public their own activities in databasing particular families worldwide - if they have the time, money, inclination, and the altruism, especially the altruism. -- Geoff Read -- ANNELIDA LIST Discuss = = talk to all members Server = = un/subscribes Archives = http://www.bio.net:80/hypermail/ANNELIDA/ Resources = http://biodiversity.uno.edu/~worms/annelid.html -- From daemon Wed Jul 28 15:18:59 1999 Received: by net.bio.net (8.9.1a/8.9.1) id PAA24146; Wed, 28 Jul 1999 15:18:59 -0700 (PDT) Date: Wed, 28 Jul 1999 15:18:59 -0700 (PDT) Message-Id: <199907282218.PAA24146@net.bio.net> To: annelida@net.bio.net From: "Kristian Fauchald" Reply-To: annelida@net.bio.net Subject: Re: Bobbit Worm This is a case which tells us how very unfortunate it is to use popular names! (Very nearly as unfortunate as Mr. Bobbit was in the first place). Eunice aphroditois is the type of the genus Eunice. The story is a bit complex taxonomically, but the name Eunice gigantea is under any circumstances invalid and cannot be used. The worm was first described by Pallas as Nereis aphroditois in 1766 I believe. What little gut content I have looked at, suggests that the worms feed on algal remnants and so forth, but that they also will grab swimming crustaceans. The snap mechanism of the jaws were described very ably for a related species by Gesa Hartmann-Schroeder some time ago and is one of the characteristic features of jaws of lumbrinerids, onuphids and eunicids. The illustrations of the worms sitting upright with the jaws cocked come both from the Philippines and from the Virgin Islands, perhaps not the same species, but certainly very similar. I have seen them out only at dusk. It is worthwhile noting that members of this species get sexually mature at a much smaller size than these 3 m monsters, probably at less than 10cm in fact, and that most members of the populations are dead before they reach anywhere near the size of these things. Is this an escape from predation through size? They are reported to get rather old, but again the data are dubious.

This is initially a trial to see how it works and what users think about it. Comments welcome! The files currently available are Annelida (about 13,200 lots; mostly polychaetes), Mollusca (about 51,000 lots) and Vertebrata (about 16,500 lots). These are not all our holdings. Those available are only those that are item documented (fully museum registered) and transferred on to our computer database files. We will be looking at the access again in September and adjusting it as appropriate. Additional entries will be added at regular intervals as and when we get them entered on file. At present, I know that the Type (all) field is not working for some reason. This is probably something simple as the 'prerelease' version worked OK. In the 'full' results, the Family doesn't show, but you can search on Family without problems. Also, the Updated name fields are not showing up, but this is simply because I haven't filled them all in yet! When the Update fields are operational, please bear in mind that this will simply be an electronic conversion and will not imply verification of the specimen. Anyway, these little problems aside, I'd appreciate comments. The fields available on the net are not all that we have in our full databases so, if required, we could make others accessible.
