The position of the Arthropoda in the phylogenetic system
TLDR
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.
New insights into polychaete phylogeny (Annelida) inferred from 18S rDNA sequences.
TLDR
The results support the assumption that on the basis of a broader taxon sampling the phylogenetic position of controversially discussed taxa can be inferred by using 18S rDNA sequence data.
A contribution to sedentary polychaete phylogeny using 18S rRNA sequence data
TLDR
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.
CHAETOGENESIS IN POLYCHAETOUS ANNELIDA : SIGNIFICANCE FOR ANNELID SYSTEMATICS AND THE POSITION OF THE POGONOPHORA
Ultrastructure of the body cavities in Phylactolaemata (Bryozoa)
TLDR
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
TLDR
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.
Structure and formation of the uncini in Pectinaria koreni, Pectinaria auricoma (Terebellida) and Spirorbis spirorbis (Sabellida): inplications for annelid phylogeny and the position of the…
TLDR
It can be concluded that Arenicolida, Maldanida and Psammodrilida are closely related to the monophylum consisting of Terebellida, Sabellida and Pogonophora, and that these six taxa share a common ancestor, which evolved transverse rows of setae with apically curved spines and a formative site lateral to the edge of the neuropodial rim.
The complete mitochondrial genome of the orbiniid polychaete Orbinia latreillii (Annelida, Orbiniidae)--A novel gene order for Annelida and implications for annelid phylogeny.
TLDR
A comparison of the available data shows that gene translocations within Annelida seem to be less frequent than in molluscs, but more frequent as previously assumed, and a closer relationship to orbiniids is recovered for this taxon.
The linguistic problem of morphology: structure versus homology and the standardization of morphological data
TLDR
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.
Ganglion ultrastructure in phylactolaemate Bryozoa: Evidence for a neuroepithelium
TLDR
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.
