1. Ecosystem engineers can influence other organisms indirectly by modifying their physical habitat and are common in all natural communities. We examined the mechanisms underlying the effects of engineering by seaside arrowgrass, Triglochin maritima (Juncaginaceae), in a northern New England forb panne. Within these waterlogged areas, T. maritima creates elevated rings that support high plant cover compared with nearly bare adjacent substrate.

2. The influence on vegetation patterns of ring height and facilitation by neighbouring vegetation were examined in the field with T. maritima rings (elevation + vegetation), experimentally lowered rings (vegetation only), artificially raised mud (elevation only) and bare mud. Transplants of four perennial species, along with naturally occurring seedlings, were followed to assess plant performance. We also monitored edaphic conditions, seed dispersal and plant cover in experimental plots over two growing seasons.

3. All transplanted species showed increased success in raised treatments (in which the substrate showed an increase in reductive potential and a decrease in waterlogging) while there was no significant relationship to the presence of neighbouring vegetation. Seed supply, however, was enhanced by both ring elevation and the presence of neighbours.

4. A glasshouse experiment to test the response of T. maritima to waterlogging showed an increased production of shallow roots, suggesting a mechanism that may contribute to ring formation.

5. Our results indicate that community consequences of engineering by T. maritima are predominantly due to raised ring formation that ameliorates waterlogging stress and thereby promotes increased species diversity. Consequently, T. maritima may be an important target species for conservation, as sea level rise is expected to increase waterlogging stress in marshes.

The effect of cold stratification treatment and isoosmotic NaCl and polyethyleneglycol (PEG) concentrations on germination of Triglochin maritima seeds was assessed. The highest (400 mM) NaCl concentration caused a significant decrease in germination percentage and no germination was observed at the two highest (64 and 128 mM) PEG concentrations. The large difference in germination among experiment replications suggests that time of collection and length of storage may have influenced germination. Stratification treatment had a significant positive effect on seed germination and there was a significant interaction between PEG, but not NaCl, concentration and duration of cold stratification during germination. Further research is required to determine the importance of the degree of seed ripeness as well as the possible effect of after-ripening or induction of secondary dormancy of undispersed seeds on seed germination.
