Tracing viable bacteria in Wadden Sea sediments using phospholipid analysis
This thesis describes a protocol that was developed to analyse different types of lipids from bacteria and sediments. Special emphasis was placed on the analysis of intact phospholipids by HPLC-ESI-MS/MS, because phospholipids appear to be suitable biomarkers to trace viable bacteria. The …

Reproduction of coastal birds breeding in the Wadden Sea: variation, influencing factors and monitoring
… its variability of coastal birds breeding in the Wadden Sea. A further aim was to assess the contribution of current breeding success to population trends of single species. The studies were conducted during the mid 1990s and at the beginning of the 2000s investigating six frequent breeding bird …

„The spatial and temporal link between Common Terns Sterna hirundo and their prey fish in the Wadden Sea“
Der Einfluss räumlicher und zeitlicher Verteilungsmuster von Fischen auf die Reproduktion von Flussseeschwalben im Wattenmeer wurde untersucht. Langfristige Veränderungen des Bruterfolges konnten mit der Heringsabundanz in der Nordsee erklärt werden. Die Nahrungsfischdichte hatte einen größeren …

Tidally Induced Transport Dynamics in a Wadden Sea Tidal Basin and Its Changes Under Future Sea Level Rise Scenarios
Coastal systems in the Wadden Sea are shaped by the interplay between tidal dynamics, basin geomorphology, and atmospheric forcing. These interactions create spatial structures of hydrodynamic connectivity that govern transport processes, ecological functioning, and the interpretation of long-term …

Born to fly - migratory strategies and stopover ecology in the European Wadden Sea of a long-distance migrant, the Bar-tailed Godwit (Limosa lapponica)
Although large numbers of birds visit the Wadden Sea each year, consumption by birds amounts only to 8.7 g AFDM m-2 a-1 which equals 10-25 % of the secondary production. A main consumer is the Bar-tailed Godwit. In the Wadden Sea a European and an Afro-Siberian population of Bar-tailed Godwits …

Evaluation of spatial and temporal models to assess the bioaccumulation of trace metals in marine invertebrates
… of the benthic communities in the Wadden Sea in the Wadden Sea and the southern North Sea with substantial economic impact. For both species the problem of spatial dependence was addressed on two different scales. In either case the goal of the studies was to quantify the range of …

Untersuchungen auf Sekundärstoffproduktion und physiologische Charakterisierung von marinen heterotrophen Bakterien aus dem deutschen Wattenmeer
… bacteria, over 90 isolates from the german Wadden Sea were screened for their potential for secondary metabolite production. 16 S rRNA gene analysis revealed, that 56 strains affiliated with Gram positive bacteria and 36 strains with the Roseobacter-clade (alpha-Proteobacteria). To avoid the …

Do microbial or biochemical settlement cues on the sediment surface mediate larval settlement of Polydora cornuta and Streblospio benedicti (Polychaeta, Spionidae)?
… found in sediments of tidal flats in the German Wadden Sea. These patterns were not explicable through grain size or other sediment parameters. This led to the hypotheses that active site selection and initial settlement of larvae were triggered by sediment associated microbial cues of i.e. …

Geochemical tracers in the deep-sea and the North Sea
… about the inorganic geochemistry of the deep-sea and the North Sea, which have been published or submitted for publication. Typical element/Al ratios indicate eolian, continental input of loess material during the last Heinrich-events. In the Arabian Sea, the climatic influence on the …

Community, structure, activity and ecophysiology of sulfate-reducing bacteria in deep tidal flat sediments
… to 5 meters depth of a tidal sand flat (German Wadden Sea). The majority of the isolated and quantified SRB were members of two widely distributed phylogenetic groups within the Deltaproteobacteria. Many cultured representatives as well as the isolates from this study are able to utilize a broad …

From Representative Period Selection to Process‐Based Sediment Dynamics
The North Frisian Wadden Sea (NFWS) is a mixed-energy tidal system of interconnected tidal flats, channels, ebb-tidal deltas and barrier islands, in which tides, waves and wind jointly govern sediment transport. Despite its ecological and morphological significance, the region remains comparatively …
