Talk:Didinium

i am doing a project on didinium. There is nothing on the web obout its body parts,and its habitat. If you read this, i nee your help!

Some notes on changes I've made

The previous version of the article had a list of references at the end, but no citations within the text. Where possible, I've found sources for the claims made in the earlier version. References were added or removed, as necessary. (In some cases, the source given were not relevant to the topic. For instance, Didinia are "haptoria," not "haplosporidia," so Reece et al. is of no use here).

The section on Phylogeny was mostly a paraphrase from Riley et al (2001), except for the curious observation -- which I have been unable to verify -- that phylogeny of ciliates is inherently difficult because of their nuclear dualism. Apart from the final sentence, re. the monophyly of Haptoria, the information was not specifically pertinent to the classification of Didinium, and has been removed. In its place, I inserted a brief history of Didinium classification, and cited two sources for the paraphyly of Haptoria.

I altered the section on D. nasutum to reflect the established fact that its diet is more "plastic" than some sources suggest (ie, not confined to Paramecium).

Some other changes:

• Moved species list to end of file, to improve layout. At the same time, I checked the validity of species and added authorities, where possible.

• Removed these species from the list: D. coccineum, D. commune, D. fulgens, D. maculosum, D. peyrefittense, D. protectum. None of these are species of Didinium; these are all species of Didemnum that somehow got wrongly classified in the ITIS database. I will write to ITIS and inform them of the error.

• Removed Didinium rostratum (a subspecies of D. nasutum or D. balbianii)

• Removed Didinium cinctum (a synonym for Pelagovasicola cinctus)

• Since I could not find a citation for the exact size-range claimed (40-200 micrometres), I used the range given by Alfred Kahl.

• Removed reference to trichites, an obsolete term that conflates nematodesmata and toxicysts.

• Made many minor changes, e.g changed plural "pectinellae" to the more modern "pectinelles", following the practice of Denis Lynn. Also, removed some distracting links to terms that do not need clarification (such as "length")
