The position of the Arthropoda in the phylogenetic system
- A. Schmidt-Rhaesa, T. Bartolomaeus, C. Lemburg, U. Ehlers, J. Garey
- BiologyJournal of morphology

There are morphological characters that support Articulata, but molecular as well as morphological data advocate Ecdysozoa, and comparative morphology suggests Gastrotricha as the sister group of Ecdy sozoa with the synapomorphies.

Ultrastructure of the body cavities in Phylactolaemata (Bryozoa)
- Alexander Gruhl, Ines Wegener, T. Bartolomaeus
- BiologyJournal of morphology
- 1 March 2009
Only species belonging to the bryozoan subtaxon Phylactolaemata possess an epistome, and there is no indication for an excretory function of the forked canal, especially as no excreteory porus was found.
Ultrastructure and formation of the hooked setae in Owenia fusiformis delle Chiaje, 1842: implications for annelid phylogeny
- K. Meyer, T. Bartolomaeus
- Biology
- 1 December 1996
Based on the hypothesis that these specific setae characterize a monophyletic group within the Annelida, the structure and development of the hooked seta in Owenia fusiformis are analysed and compared with data from other annelids with such setae.
A contribution to sedentary polychaete phylogeny using 18S rRNA sequence data

It is suggested that an increase in taxon sampling may yield additional resolution in the reconstruction of polychaete ingroup phylogeny, although the difficulties in reconstructing the basal phylogenetic relationships within Annelida may be due to their rapid radiation.

The linguistic problem of morphology: structure versus homology and the standardization of morphological data
- Lars Vogt, T. Bartolomaeus, Gonzalo Giribet
- Linguistics
- 7 October 2009
The present article discusses the need for standardization in morphology in order to increase comparability and communicability of morphological data, and argues that this structure concept can be represented with knowledge representation languages such as the resource description framework (RDF) and that it can be applied for morphological descriptions.
Mitochondrial sequence data expose the putative cosmopolitan polychaete Scoloplos armiger (Annelida, Orbiniidae) as a species complex
- C. Bleidorn, I. Kruse, Sylvia Albrecht, T. Bartolomaeus
- BiologyBMC Evolutionary Biology
- 15 June 2006
The results of this study clearly supports that Scoloplos armiger represents a species complex and not a cosmopolitan species, as well as clarifying the systematics of this species complex in the Eastern North Atlantic while using a few specimens from the Pacific Ocean for comparisons.
Ganglion ultrastructure in phylactolaemate Bryozoa: Evidence for a neuroepithelium
- Alexander Gruhl, T. Bartolomaeus
- BiologyJournal of morphology
- 1 May 2008
A comparison with potential outgroups reveals that a neuroepithelial ganglion in the subtaxon Phylactolaemata is at least derived, since a reliable phylogenetic system of the Bryozoa is missing, and a decision on whether such a ganglions is apomorphic for BryozOA or evolved within this taxon can hardly be made.
Polychaete phylogeny based on morphological data – a comparison of current attempts
- T. Bartolomaeus, G. Purschke, H. Hausen

- 2004
There is at least strong support for the Annelida as wells as for several of its taxa above the level of traditional families; the monophyly of the Polychaeta, however, remains questionable.
