“…It rapidly spread along the mainland coasts of the North Sea (Essink & Kleef 1988, 1993 and reached the western Baltic Sea in 2004 (Bastrop & Blank 2006). An almost simultaneous spread of the sibling species Marenzelleria neglecta occurred in the southern and central Baltic Sea (Sikorski & Bick 2004). A salinity of ~10 seems to delimit the distribution of these 2 species in the Baltic Sea, with M. viridis restricted to salinities above and M. neglecta to salinities below this level.…”

The contrasting effects of the invasive Marenzelleria viridis and the native Nereis diversicolor on benthic metabolism, partitioning of reaction pathways and distribution of inorganic porewater (C and N) solutes in homogenized sandy sediment were investigated experimentally over a period of 1 mo. The 2 species were studied separately and in combination to observe possible effects and interactions. Benthic O 2 uptake and total CO 2 (TCO 2 ) release were affected similarly by M. viridis, N. diversicolor and the two in combination, with roughly a doubling after 1 to 2 wk compared to defaunated sediment. Sulfate reduction after 1 mo, on the other hand, was more than twice as high in sediment inhabited by M. viridis alone than in any other treatment, even when combined with N. diversicolor. Denitrification estimated from benthic TCO 2 release, porewater reaction stoichiometry and nutrient fluxes was largely unaffected by the presence of fauna. Accordingly, the partitioning of reaction pathways after 1 mo revealed that M. viridis stimulated sulfate reduction at the expense of aerobic respiration. Most of the oxygen uptake in M. viridis sediment was apparently due to enhanced oxidation resulting from an upward drifting front of sulfide as indicated by low redox and the appearance of Beggiatoa sp. near the surface. Porewater solute profiles showed that M. viridis was capable of stronger and deeper irrigation than N. diversicolor despite ~10 times higher burrow ventilation by the latter species. This effect was caused by percolation of return water in the deep (> 20 cm) I-or J-shaped burrows of M. viridis compared to the flushing of the more shallow (6 to 8 cm) U-shaped burrows of N. diversicolor. A replacement of the native N. diversicolor with the invasive M. viridis as the dominant burrow-dwelling polychaete in shallow coastal sediments will probably affect the biogeochemical functioning and ecological stability of the ecosystem. Among other things, organisms tolerant to sulfide are likely to be favored at the expense of more sensitive species.

Studies of Marenzelleria species were often hampered by identification uncertainties when using morphological characters only. A newly developed PCR/RFLP protocol allows a more efficient discrimination of the three species Marenzelleria viridis, Marenzelleria neglecta and Marenzelleria arctia currently known for the Baltic Sea. The protocol is based on PCR amplification of two mitochondrial DNA gene segments (16S, COI) followed by digestion with restriction enzymes. As it is faster and cheaper than PCR/sequencing protocols used so far, the protocol is recommended for large-scale analyses. The markers allow an undoubted determination of species irrespective of life stage or condition of the worms in the samples. The protocol was validated on about 950 specimens sampled at more than 30 sites of the Baltic and the North Sea, and on specimens from populations of the North American east coast. Besides this test we used mitochondrial DNA sequences (16S, COI, Cytb) and starch gel electrophoresis to further investigate the distribution of the three Marenzelleria species in the Baltic Sea. The results show that M. viridis (formerly genetic type I or M. cf. wireni) occurred in the Ö resund area, in the south western as well as in the eastern Baltic Sea, where it is found sympatric with M. neglecta. Allozyme electrophoresis indicated an introduction by range expansion from the North Sea. The second species, M. arctia, was only found in the northern Baltic Sea, where it sometimes occurred sympatric with M. neglecta or M. viridis. For Baltic M. arctia, the most probable way of introduction is by ship ballast water from the European Arctic. There is an urgent need for a new genetic analysis of all Marenzelleria populations of the Baltic Sea to unravel the current distribution of the three species.

We ask the question whether differences in transport rates and mode are related to burrowing depth and if the three species are indeed alike.…”

The invasive spionid polychaetes of the genus Marenzelleria spp., consisting of the three sibling species M. neglecta, M. viridis, and M. arctia, has been found in the Baltic Sea since the 1980s. Because of difficulties in species identification, little is known about species-dependent sediment reworking and solute transport. The closely related species are apparently similar in feeding and sediment-dwelling behavior, but size and burrowing depth indicate differences in bioturbation and the biogeochemical consequences thereof. To investigate these potential differences, a tracer experiment with artificial particles (luminophores) and solute tracer (bromide) was conducted. Polychaetes were identified to species level using a molecular genetic key. Modeled results show that all three species display markedly low particle reworking rates with biodiffusion coefficients (Db) of 1.76 cm 2 yr 21 (M. viridis) and 0.07 cm 2 yr 21 (M. neglecta) at an abundance of 1273 individuals m 22 and 0.44 cm 2 yr 21 (M. arctia) at twice that abundance. Nonlocal transport coefficients are negligible in all cases. Solute transport by M. neglecta and M. viridis are more similar to one another than to M. arctia, whose solute transport mode is much more diffusive in character (10.9-fold enhanced diffusivity with nonlocal irrigation coefficients [a] of 55.3 yr 21 ) than that of the two other species, which affect tracer distributions in the sediment predominantly through a nonlocal, advective transport mode (a of 108.9 yr 21 M. viridis and 130.9 yr 21 M. neglecta). Thus, a functional grouping of the sibling species in terms of bioirrigation is not recommended.
