“…Evaporation was highest in the early summer with the average kettle hole evaporative loss amounting to 38% of the kettle hole water volume, ca. 5,200 m 3 of water, consistent with estimates from temporary kettle holes in this area (Nitzsche et al, 2017). Furthermore, the kettle holes with the shortest hydroperiods tended to have the largest estimates of evaporative loss.…”

“…The sediment isotopic variability was large, and any differences between the edge and centre sediments were not detectable. This large isotopic variability is similar to what was found for surface (0-2 cm) and deeper (2-75 cm) sediments in kettle holes from a larger survey of kettle hole hydroperiod types (Nitzsche et al, 2017). We placed our sediment samples in the previously found relationship between sediment OM δ 15 N and C:N of deeper sediments (Figure 8), which aligned to these previous results.…”

“…Although kettle hole hydroperiod is considered a dominant driver of water quality and water levels (Berthold, Bentley, & Hayashi, 2004;Gołdyn, Kowalczewska-Madura, & Celewicz-Gołdyn, 2015) as well as sediment biogeochemistry (Nitzsche et al, 2017), the potential connectivity of kettle holes or other isolated water bodies to groundwater can also have an impact on water quality (Rains, Fogg, Harter, Dahlgren, & Williamson, 2006). Whether a water body is strictly precipitation fed or part of a groundwater flow through network will in part determine the inflow and outflow of nutrients (e.g., NO 3 − , NH 4 + , PO 4 3− , etc.)…”

Kettle holes are glacially created ponds that form within landscape depressions and are numerous across young moraine landscapes. Kettle hole water budgets are based primarily on winter precipitation, and therefore, undergo pronounced short‐term changes in water level fluctuations. Little is known about kettle hole sediment biogeochemistry in NE Germany, especially with regards to hydroperiod. Our objective for this study was to link the abiotic influences demarked by the evaporative isotopic signal from kettle hole water and solute chemistry to sediment organic matter turnover imprinted in the sediment δ13C and δ15N isotopic values. From the 20 kettle holes we sampled, 19 of these completely dried out, but on different dates. This dynamic was partially explained by longitudinal and elevational changes over the catchment area illustrating regional controls of kettle hole water balance. At the scale of an individual kettle hole, we estimated evaporation explained up to 38% of water volume loss. The changes in water levels were weakly related to differences in surface sediment elemental N and C concentrations between kettle hole edge and centre positions. These dynamics were primarily driven by redox conditions, Ca2+, and several nutrient concentrations (dissolved organic carbon, total dissolved nitrogen, total dissolved P, and ammonium) in the water column. Although we did not detect differences in the surface sediment δ13C and δ15N values, the δ15N signature in relation to the C:N ratio highlights the advanced decomposition state of surface sediment OM in temporarily water filled kettle holes.

Local biodiversity patterns are expected to strongly reflect variation in topography, land use, dispersal boundaries, nutrient supplies, contaminant spread, management practices, and other anthropogenic influences. Contrary to this expectation, studies focusing on specific taxa revealed a biodiversity homogenization effect in areas subjected to long-term intensive industrial agriculture. We investigated whether land use affects biodiversity levels and community composition (α-and β-diversity) in 67 kettle holes (KH) representing small aquatic islands embedded in the patchwork matrix of a largely agricultural landscape comprising grassland, forest, and arable fields. These KH, similar to millions of standing water bodies of glacial origin, spread across northern Europe, Asia, and North America, are physico-chemically diverse and differ in the degree of coupling with their surroundings. We assessed aquatic and sediment biodiversity patterns of eukaryotes, Bacteria, and Archaea in relation to environmental features of the KH, using deep-amplicon-sequencing of environmental DNA (eDNA). First, we asked whether deep sequencing of eDNA provides a representative picture of KH aquatic biodiversity across the Bacteria, Archaea, and eukaryotes. Second, we investigated if and to what extent KH biodiversity is influenced by the surrounding land use. We hypothesized that richness and community composition will greatly differ in KH from agricultural land use compared with KH in grasslands and forests. Our data show that deep eDNA amplicon sequencing is useful for in-depth assessments of cross-domain biodiversity comprising both micro-and macro-organisms, but has limitations with respect to single-taxa conservation studies. Using this broad method, we show that sediment eDNA, integrating several years to D. Ionescu and M. Bizic contributed equally to the work.
