But since there are two nice distinct words, they can also be used to distingush different degrees of regularity in body organization as follows: Segmentation: body plan in which two or more tissues or organs systems (such as nervous, muscular, excretory, circulatory and/or integumental) are organized metamerically along the A-P axis of the animal; metamers of different systems have the same repeat length. Metamerism: body plan organization featuring repeating units along the A-P axis but falling short of the rigorous definition of segmentation, e.g., only one organ system is arranged into repeating subunits, or the spatial repeat lengths are different between systems. With this set of definitions, one can perhaps distinguish metamerism (in flatworm, molluscs, nematodes) from segmentation (in most annelids, arthropods and vertebrates).

Whith in nematoda I know only the presence of a segmented cuticle, and in monoplacophora molluscs segmentation could be a true metamerisms! It is not so easy! However I think is better to leave the term metamerism as basical and in some cases segmentation could be used as synonym of metamerism.

Here is Lankester's view of metamerism. Lankester, E.R. (1904). The Structure and Classification of the Arthropoda. Quarterly Journal of Microscopical Science s2-47: 523-582 "The body of the Arthropoda is more or less clearly divided into a series of rings, segments, or somites, which can be shown to be repetitions one of another, possessing identical parts and organs which may be larger or smaller, modified in shape or altogether suppressed in one somite as compared with another. A similar constitution of the body is more clearly seen in the Chaetopod worms. In the Vertebrata also a repetition of units of structure (myotomes, vertebrae, etc.) ? which is essentially of the same nature as the repetition in Arthropods and Chaetopods, but in many respects subject to peculiar developments?is observed. The name "metamerism" has been given to this structural phenomenon because the " meres," or repeated units, follow one another in line." There is much, much more, showing the joy of morphologists of the time in inventing terminology that is obfuscating rather than illuminating, but one can see from the above that metamerism is a relatively abstract term, that we can debate as to its precise meaning and scope. Perhaps it would be best to stay with feet on the ground and use easily understood words for observable things such as segmentation. Alternatively, bring back Mesmerism, and all the other 'isms ....

"But it is to be noted that in the higher members of each great class or line of descent, the tagmosis becomes definite and characteristic just as do the total number of meres or somites, whilst in the lower grades of each great class we find what may be regarded as varying examples of tentative tagmosis. The terms nomotagmic and anomotagmic are applicable with the same kind of implication as the terms nomomeristic and anomomeristic. The FOURTH LAW of metamerism (auto-heterosis of the meromes) is that the meromes of a somite or series of somites may be separately and dissimilarly affected by heteromerism. It is common enough for small changes only to occur in the inner visceral meromes, whilst the appendages and terga or sterna are largely changed in form. But of equal importance is the independent "heterosis" of these visceral meromes without any corresponding heterosis of the body-wall." >>> On 12/11/2008 at 10:15 a.m., "J.

I do believe that ecology (and perhaps biology) is contaminated with wordy jargon. My field is population dynamics, i.e. changes in population numbers: one of the main problems is terminology. It is striking how while some authors pursue the definition of ecological laws from concepts / theories / hypotheses (in population dynamics) as the holy grail, there is no consensus about what the basic term REGULATION stands for. The situation gets worse for controversial terms like DENSITY DEPENDENCE despite its use has rocketed in the ecological literature during the last 20 years. I sometimes think that a taxonomy of concepts is required in ecology (and perhaps biology), where the acceptance and validity of terms should be subjected to rules and authorship. Terminological consensus is required at the expense of individual egos, and across disciplines and research approaches (theoretical versus empirical, or pure versus applied science). The tax we pay for lack of terminological consensus is lack of communication.

Not much is known about swarming in enteropneusts (they're not usually muscle powerhouses, but obviously when there's a need there's a way).

One category of 'signs' is the tubes made by certain freshwater and marine worms. I am interested in information on which taxa make these, and how exactly they go about constructing them. I have collected photos of a few such tubes here: http://charleyeiseman.com/annelid.html and I'm hoping someone can tell me what they are (or might be). There is also a question about earthworm burrows at the bottom of that page. The book will include photos of the egg cases of *Eisenia foetida* and an unidentified leech. If anyone can provide information on variations in size, structure, and appearance among the egg cases of North American annelids, that would be very helpful. I will also be discussing earthworm castings and the midden piles of *Lumbricus terrestris* (I have photos of both), as well as the effects on forest soils of introduced earthworms in general. I live in New England and I'm unclear on the importance of exotic earthworms south of the glaciated region, so comments on that would be helpful. I think that essentially covers the annelid signs I'm aware of at this point. I would welcome any suggestions of other phenomena to consider, or contributions of any photographs that would augment the ones I've already mentioned.

The item is not held by my library, I wonder whether you may have a pdf copy of this paper. See full reference below. Neave, F. 1954. Principles affecting the size of pink and chum salmon populations in British Columbia. J. Fish. Res. Board Can. 9:450-491. In passing, I should point out that my review shows that there are only 3 papers on polychaete density-dependent issues in the high IF ecological literature from MEPS to Nature. Thanks in advance for your support.

You are correct that photo #3 is Diopatra cuprea. Similar tubes are built by Diopatra ornata and Diopatra splendidissima on the Pacific coast, but both occur subtidallly or in the very low intertidal. In Florida, Americonuphis magna builds similar tubes, and occurs in the same places as D. cuprea. Adult A. magna tubes are much tougher than D. cuprea tubes--D. cuprea can be torn easily while A. magna cannot--but juvenile A. magna tubes are hard to distinguish from D. cuprea. Some terebellid polychaetes build vaguely similar tubes with attached debris, but they tend to stick straight up rather than curving over. I would guess that your picture #2 is a maldanid, but I won't swear to it. Oweenia is possiible, but their tubes tend to be darker. They also have a distinctive shingled-together look that can be seen with a hand lens. It does not look like Pectinaria; pectinaria build very distinct cone-shaped, brittle tubes with the wide end buried and just the narrow tip sticking out. There are many many polychaete taxa that build tubes, and frankly lots of them are rather nondescript little sandy things. Spionids, maldanids, capitellids, oweniids and onuphids are some examples--and of course there are lots of crustaceans that build little sandy tubes (i.e. amphipods and tanaids). Characteristics such as how far the tube sticks up, how rigid it is, and how tough it is can all help narrow things down to the family level. For example, both Kinbergonuphis jenneri and many maldanid species build straight, emergent, sandy tubes; they look very similar but if you pull on them Kinbergonuphis tubes are stretchy while maldanid tubes break easily. Your best bet is probably to take photos of tubes, make some notes about their physical characteristics, then dig them up, pickle the worms, and key them out. Also note that many polychaetes can be identified to family based on their feces, which frequently occur near the tubes. If you're interested in polychaetes with very distinictive tubes, you might want to include Pista pacifica from the Northeast Pacific and Lanice conchilega from the northern Atlanic. Both are terebellids that build tubes with elaborate fringed crowns that are used in suspension feeding. I don't know how far you want to run with this, but it would be cool to have a field guide that really does justice to polychaete surface traces. If you haven't already, you should check out Ruppert and Fox's Seashore Animals of the Southeast and Kozloff's Seashore life of the Northern Pacific Coast. I hope that was helpful. Sadly, I have no expertise with earthworms or freshwater annelids, so I cannot help you there.
