I think that it should be emphasize the studies on population dynamics on hydromedusae.
I made my Thesis on Population Dynamics of Olindias sambaquiensis in southern area
of Buenos Aires, Argentin (it was under the direction of Dr. Hermes Mianzan)
Most of works on population are made on scyphozoa and ctenophore. It seems that hydrozoa medusa are difficult to
handle, to measure and to sample. But I think it is important to study of hydromedusae population dynamics since they may be
very abundant, may affect fiheries and many of them can painfully sting: Olindias sambaquiensis,Olindias tenuis, Liriope tetraphylla, Gonionemus vertens,
etc. These medusa may affect the people's health in touristic areas.
I think that the study of species like those may help to understand some importants aspects like growth rates, feeding rates, their impact on mesozooplankton as well as a control of population in case
that they be stinging hydromedusae.

A collaborative effort to create an ETI CD (of the sort recently published for the Euphausiids on the Linnaeus software) would be really cool. It would provide interactive keys for ID, images, biological and distributional info, and anything else we wanted it to have. I would be pleased to help organize this if other people are interested.

I think a database of hydrozoan distribution would be useful. As many species as possible (hydromedusae, hydroids, siphonophores and chondrophorines) should be included. They could be arranged in alphabetical order by generic name. Next to that name could be the known localities that the species occurs.
I think many would agree that this would be useful.

I am interested to know about distribution of hydrozoa, particulary hydrozoa thecata (polyp) from anywhere. I have little problem to get this information. Please if you know about that, tell me. Oke thank's.

I am interested to learn how velella and
other similar organisms communicate with
other parts of the collective organism.
I think a mailing list would be a great thing.
The mailing list could be archived and thus
it could function as a datasource for the
database you envision.
listserv should be available for free for
a project such as this where no money is
collected from participants.
Let me know.
Thanks,
Troy

PROPOSED SPECIES LIST FOR PROJECT HYDROZOA
from Claudia Mills, March 1999
Following is a list of 76 species of Hydrozoa that might be considered by the Project Hydrozoa as core species. This species list has been arrived at with suggestions from a number of hydrozoan workers, but should not be considered fixed or final. We understand that Antonio Marques is working on filling in a data matrix for all Hydrozoa from which he expects to turn up a smaller species sublist, but such a list may take years to define and may not include common species that deserve our consideration even if little has been done on them in the past.
Species included here are deemed to be of fairly wide geographical distribution (most are from the northern hemisphere, but species found in both hemispheres are especially welcome) and are largely easily identified and without difficult, associated taxonomic problems (perhaps with the exception of the species of Obelia). It is hoped that the community of hydrozoan workers will make extra efforts to include members of the core set of species in their work in order to fill in a comparative public database from which anyone might eventually work on phylogenetic and evolutionary questions.

To render the data more accessible, would it be possible to propose a list of key words for the subjects which would be easier to enter and easier to read and classify, as proposed in BBay ?
Thanks to Allen for the HS page, it was a true pleasure to open and discover it this morning.
On the web page HS logo ressembles after me more and more to "polmones", "poumons", I did not remember the english term... I like the reallistic logo of Project Hydrozoa.

I have the complete 18S gene sequence for the
following hydrozoan species:
Aequorea_aequorea, Aequorea_victoria, Aegina_citrea,
Liriope_tetraphylla, Crossota_undescribed_sp.,
Crossota_rufobrunnea, Haliscera_conica, Praya_dubia,
Physophora_hydrostatica, Polyorchis_haplus,
Moerisia_sp., Cladonema_californicum,
Bougainvillia_sp., and Maeotias_inexspectata.
In addition, GenBank has the following sequences:
Selaginopsis_cornigera, Gymnangium_hians,
Hydra_littoralis, and Coryne_pusilla.
In the future, I plan on generating additional
sequences of the 18S gene and would be willing
to determine the molecular sequence of other
genes that show promise for resolving deeper
evolutionary relationships. Such genes are
RNA Polymerase II, Elongation Factor-1alpha,
Heat Shock Protein 70, and others.
I always welcome tissues, so contact me if you
have something you think would be interesting. Thanks.
