Revision of the genus Spiophanes (Polychaeta, Spionidae); with new synonymies, new records and descriptions of new species
The paper presents a comprehensive revision of the genus Spiophanes (Polychaeta, Spionidae) based on type material and describes 8 species, including the type species, S. kroyeri, which is raised to species status. Expand
A Reverse Taxonomic Approach to Assess Macrofaunal Distribution Patterns in Abyssal Pacific Polymetallic Nodule Fields
This work tested to what extent distance and large-scale changes in environmental parameters lead to differentiation in two macrofaunal taxa exhibiting different functions and life-history patterns, and indicated high local and regional diversity mostly because of large numbers of singletons in the samples.

Spiophanes norrisi sp. nov. (Polychaeta: Spionidae)a new species from the NE Pacific coast, separated from the Spiophanes bombyx complex based on both morphological and genetic studies
Genetic differences between S. bombyx and S. norrisi in both examined genes are significant and genetic distances are comparable to distances found between sister species in other spionid taxa, but conclusions about the phylogenetic relationships and character evolution within Spiophanes must remain tentative.

Infestation patterns of microphallid trematodes in Corophium volutator (Amphipoda)
Seasonal and interannual alterations in infestation among the amphipod population are described, with increasing prevalences and relative infestation intensities over the summer, with the highest values in late summer and autumn. Expand
Histochemical evidence of β‐chitin in parapodial glandular organs and tubes of Spiophanes (Annelida, Sedentaria: Spionidae), and first studies on selected Annelida
The results of this study provide strong evidence that Spiophanes species, O. fusiformis and probably also G. orestes produce chitin and supposedly use it for tube‐building, which implies that the production of chit in and its use as a constituent part of tube‐ building is more widespread among polychaetes as yet known.

Mortality of Corophium volutator (Amphipoda) caused by infestation with Maritrema subdolum (Digenea, Microphallidae)--laboratory studies
A strong negative correlation between the density of cercariae in the dlsh and the average survival times of C. volutator as a result of M. subdolum infestation seems to be an exceptional but conceivable occurrence in shallow water areas of the Baltic Sea. Expand
Population dynamics and ecoparasitological surveys of Corophium volutator in coastal waters in the Bay of Mecklenburg (southern Baltic Sea)
Ecoparasitological analysis revealed that mortality in the extremely heavily infested spring generation was unusually high, and this had a direct impact on subsequent reproductive processes, showing that parasite infestation is a factor that can affect population development. Expand
The IceAGE project – a follow up of BIOICE
The Nordic Seas, i.e. the Greenland, Iceland and Norwegian Seas (GIN Seas), and the northernmost part of the North Atlantic Ocean, are characterized by sev− eral local peculiarities like submarineExpand
Laboratory Studies of Parasite Transmission Aspects between Hydrobia spp. (Gastropoda) and Corophium volutator (Amphipoda)
Under natural conditions the cercariae, after emerging, have a maximum period of I day in which to seek out their second intermediate host C. volutator, and other effects of infestation, as observed in the authors' experiment, can be assumed to be a result of the penetration process of the cerbariae but they also can be attributed to the mesocercariaes.

Benthic Habitats Around Iceland Investigated During the IceAGE Expeditions
During the IceAGE (Icelandic marine Animals – Genetics and Ecology) expedi− tions in waters around Iceland and the Faroe Islands in 2011 and 2013, visual assessments of habitats and the study ofExpand
