Ultrastructure of the body cavities in Phylactolaemata (Bryozoa)
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. Expand
Myxozoan Evolution, Ecology and Development
This book provides an up-to-date review of the biology of myxozoans, which represent a divergent clade of endoparasitic cnidarians. Myxozoans are of fundamental interest in understanding how earlyExpand
Ganglion ultrastructure in phylactolaemate Bryozoa: Evidence for a neuroepithelium
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.

Development and myogenesis of the vermiform Buddenbrockia (Myxozoa) and implications for cnidarian body plan evolution
The polarised primary body axis represents an ancient feature present in the last common ancestor of Cnidaria and Bilateria and may represent convergent evolution to a bilaterian condition. Expand
Diversification and repeated morphological transitions in endoparasitic cnidarians (Myxozoa: Malacosporea).
P phylogenetic analyses of SSU and LSU rDNA with morphological observations are combined to substantially enhance understanding of malacosporean diversification and provide evidence that fredericellid bryozoans are the main hosts for Tetracapsuloides bryosalmonae and are therefore most relevant for research on the ecology and management of Proliferative Kidney Disease of salmonid fish.

Ultrastructure of mesoderm formation and development in Membranipora membranacea (Bryozoa: Gymnolaemata)
Mesoderm origin in Bryozoa is largely unknown. In this study, embryonic and early larval stages of Membranipora membranacea, a bryozoan exhibiting a planktotrophic cyphonautes larva, are investigatedExpand
Muscular systems in gymnolaemate bryozoan larvae (Bryozoa: Gymnolaemata)
Detailed morphological descriptions of the three-dimensional structure of muscular systems in the larvae of Flustrellidra hispida, Alcyonidium gelatinosum, Membranipora membranacea, Bugula fulva and Bowerbankia gracilis show muscular systems to be much more complex than previously recognized. Expand
Neuromuscular system of the larva of Fredericella sultana (Bryozoa: Phylactolaemata)
The separate origin of larval and adult serotonergic nervous systems, which remain unconnected is most likely ancestral and apomorphic for Bryozoa and argues for the homology of bryozoan larval forms. Expand
An Introduction to Myxozoan Evolution, Ecology and Development
It is concluded that myxozoans now merit broad recognition as a clade exhibiting comparable patterns of species richness and host exploitation to those of macroparasites but which has converged on strategies of micropar asites (parasitic protists) for host exploitation. Expand
Serotonergic and FMRFamidergic nervous systems in gymnolaemate bryozoan larvae
The larval nervous systems of the four gymnolaemate species Flustrellidra hispida, Bugulafulva, Alcyonidiumgelatinosum, and Bowerbankiagracilis are examined by means of antibody staining against the neurotransmitters serotonin and FMRFamide, as well as against acetylated α-tubulin. Expand
