title: SH1387013.10FU

description: UNITE provides a unified way for delimiting, identifying, communicating, and working with DNA-based Species Hypotheses (SH). All fungal ITS sequences in the international nucleotide sequence databases are clustered to approximately the species level by applying a set of dynamic distance values (<0.5 - 3.0%). All species hypotheses are given a unique, stable name in the form of a DOI, and their taxonomic and ecological annotations are verified through distributed, web-based third-party annotation efforts. SHs are connected to a taxon name and its classification as far as possible (phylum, class, order, etc.) by taking into account identifications for all sequences in the SH. An automatically or manually designated sequence is chosen to represent each such SH. These sequences are released (https://unite.ut.ee/repository.php) for use by the scientific community in, for example, local sequence similarity searches and next-generation sequencing analysis pipelines. The system and the data are updated automatically as the number of public fungal ITS sequences grows.

title: Dataset for manuscript: "<b>Impacts of reindeer grazing on phosphorus sorption and nutrient availability in a tundra site</b>"

description: Reindeer (<i>Rangifer tarandus L</i>), a large circumpolar herbivore, can influence whether nitrogen (N) or phosphorus (P) is the primary limiting nutrient in tundra plant communities. Specifically, findings from a site in northern Scandinavia suggest that under conditions where reindeer grazing stimulates inorganic N availability, grazing may drive ecosystems towards P limitation. However, the mechanisms driving such effects on tundra soil P biogeochemistry remain poorly understood. We conducted a study in this system, where heavily grazed areas locate close to long-term lightly grazed areas in both meadows and heaths in northern Norway, to assess how reindeer grazing moderates soil inorganic N and P concentrations, and particularly the relationship between P availability and soil P sorption capacity. We measured water extractable inorganic N (NH<sub>4</sub>-N and NO<sub>3</sub>-N) and water extractable P (PO<sub>4</sub>-P) concentrations, P sorption index, and the P-sorbing elements aluminium (Al) and iron (Fe). Our results demonstrate that high reindeer grazing pressure was related to higher extractable inorganic N concentrations in the organic soil layer in meadows, and a higher extractable inorganic N:P ratio in both vegetation types. Also, the higher reindeer grazing pressure significantly increased the soil P sorption index, which was positively related to soil Al + Fe concentrations and decreased extractable PO<sub>4</sub>-P in the organic layer in the heath. In the meadow, extractable PO<sub>4</sub>-P concentrations remained unchanged while the extractable N:P ratio increased from 21 to 30, thus decreasing the amount of extractable PO<sub>4</sub>-P per unit of inorganic N. We conclude that herbivores shift both habitats in our study area in the direction of P limitation, but the mechanism seems to vary from increased P sorption in the heath to increased N availability in the meadow. This shift in mechanism could be important for understanding how herbivores can influence the relative importance of N and P limitation in ecosystems across the Arctic.

title: IODP Expedition 397 Moisture and Density

description: Moisture and density (MAD) data were acquired on ~10 mL sediment or rock samples by measuring three out of four material parameters: wet (saturated) mass, wet volume, dry mass, and/or dry volume after 24 h drying in a convection oven at 105 degrees C. From the moisture and volume measurements, the following phase relationships are calculated: wet and dry water content, wet bulk density, dry bulk density, grain density, porosity, and void ratio. The combination of measurements is defined by the submethod chosen: A, B, C, or D. Wet (A, B, or C) and dry (A, B, C, or D) mass is determined using motion-compensated balances.  Wet volume is determined either by helium pycnometry (A) or by the sample's geometric dimensions using calipers (A or D).  Dry volume (C or D) is measured by helium pycnometry.  Submethods A and B are not recommended by IODP.  Submethod C is suitable for saturated materials such as fine-grained sediments.  Submethod D is suitable for unsaturated porous material such as certain limestones and basalts.
