Abstract:

Abstract. Zoanthid taxonomy is currently in a state of chaos, with many described species very few of which can be reliably identified. As part of a genetically based, objective reappraisal of the number of northern Australian species, a total of 355 zoanthid specimens were collected from 19 localities in the Great Barrier Reef and Torres Strait during 1992-1994. Specimens, initially assigned to one of ten morphological or ecological forms, were subjected to allozyme electrophoretic analysis. Analysis of genetic data revealed only seven discrete (i.e., non-interbreeding) groups in the family Zoanthidae. These groups, which are delimited by fixed gene differences, are considered species under a biological species concept. Some species show considerable morphological variation and have broad environmental tolerances. We provide the first key to Great Barrier Reef zoanthid species based on our results and observations. Species can be differentiated in the field on the basis of gross colony morphology, sand encrusting habit, polyp form and habitat. Genetic data are also used to generate a phylogenetic hypothesis of relationships among the Zoanthidae, which is compared to previous morphologically based systems. Division of the group on the basis of mesenterial arrangement appears justified, but nematocyst data appear less valuable in phylogenetic studies of the group than has been suggested previously.
you should be able to find the full article in most decent libraries, or get a ILL copy at least. The significant thing about this article is the relatively new KEY to id'ing the spp included with this article.

Being a Zoa freak myself I thank you very much for the information! Now what did the article say!:D

They need to re-do the classification on Zoo's... They originally had 10 different groups to assign zoo's to and now they have found out that there are only 7 true different zoo's (that they have been able to identify).

Thanks Don!

What the study was based on was testing and analysis of the actual genetic make-up of these zooanthids to see which ones were and were-not generically related. The taxonomy (naming) of each specie has been primarily through morphological (physical and visual) characteristics of these related organisms that group them into distinct non-interbreedable groups (species). This is one of the reasons that ID's based on physical description or photographs cannot reliably be done without delving further into the morphology of the zooanthids. In addition, there are up until now, no agreement on exactly what and how the rules for the taxonomy are or should be. Generic testing has made this a little more clear, and helps establish the ground rules for the naming and delineation of the species.

(the short version :lol: )

well, Thomas ;).....

if the public library does not carry this specialized magazine, they can get the full article for you via ILL as you said, orrrrr using Discus or some other search tool.

OK, Thurston, dahlink??:clown: :lol: :banana: :thumbup: :jester:

"Whyyyyyy YES, Lovey... ...by the way Lovie, Isn't "...Spending too much time in the Stax..." an oxymoron for those librarian-types???
