title: Quantified Volumes of White Matter Hyperintensity Spatial Patterns Generated by Voxel-Based Spectral Clustering

description: This dataset includes 1,046 unique individuals from the Alzheimer’s Disease Neuroimaging Initiative (ADNI) cohort who were selected based on the availability of baseline 3T structural MRI scans, including FLAIR and MPRAGE sequences. For each participant, demographic information such as age at scan, sex, and race is provided, along with medical history details including hypertension, diabetes, and hypercholesterolemia, as well as social history factors like alcohol use and smoking. The dataset features quantified total white matter hyperintensity (WMH) volume and volumes of five distinct WMH spatial patterns identified through voxel-based spectral clustering. These spatial patterns represent anatomically and potentially pathophysiologically unique WMH subtypes derived from advanced voxel-wise clustering analysis. The data were generated from harmonized baseline MRI, enabling standardized comparison across individuals. This comprehensive dataset supports research into WMH heterogeneity and its associations with demographic, medical, and lifestyle factors in aging and neurodegenerative diseases.

title: Elemental concentration from Greenland halibut sagittae otoliths collected in Saguenay Fjord, Estuary and Gulf of St.Lawrence (Québec, Canada)

description: Our study is based on a tremendous (n=168) and unique data set of otolith elemental concentration characterized by the Magnesium 24 (Mg μg/g), Strontium 88 (Sr μg/g) and the Barium 138 (Ba μg/g) extracted from Greenland halibut Reinhardtius hippoglossoides living in the Saguenay Fjord, Estuary and Gulf of St. Lawrence caught during the summer 2016 mission using an Alfredo III bottom otter trawl. Information about Greenland halibut such as length (mm), weight (g), capture site, depth and date were added. The otolith section (margin or core) analyzed was specified. The objective was to explore the spatial variation of the elemental fingerprints in the Estuary and Gulf of St. Lawrence and to determined the connectivity and natal source of our individuals. The elemental sectors were determined based on elemental fingerprint similarites and the natal source (origin) by clusturing random forest analysis performed on the core section of the otoliths only.

title: Plant height along the plant diversity gradient in the Jena Experiment (Main Experiment, year 2004)

description: This data set contains measurements of plant height: vegetative height (heighest leaf) in 2004 from the Main Experiment plots of a large grassland biodiversity experiment (the Jena Experiment; see further details below). In the Main Experiment, 82 grassland plots of 20 x 20 m were established from a pool of 60 species belonging to four functional groups (grasses, legumes, tall and small herbs). In May 2002, varying numbers of plant species from this species pool were sown into the plots to create a gradient of plant species richness (1, 2, 4, 8, 16 and 60 species) and functional richness (1, 2, 3, 4 functional groups). Plots were maintained by bi-annual weeding and mowing. In 2004, plant height was recorded twice a year just before biomass harvest (during peak standing biomass in late May and in late August). For plants at 3 random points in a control area at the margin of each experimental, vegetative height (heighest leaf) was measured as standing height (without stretching the plant). Provided are the individual measurements and the mean over the measured plants.
description: There are two types of missing values contained in the dataset. Empty cells represent missing values that result from the design of the experiment when the respective value does not occur and could thus not be measured. For example, in the case of species-specific biomass cells are left blank, when the species was not sown into the respective plot. Missing values that resulted from methodological problems, sampling errors, or lost samples/data are marked with "-9999".This datasets is part of a collection of measurements of plant height in the Jena Experiment. Similar data from other experiments (e.g. Main Experiment, Dominance Experiment; see details above), other years, or other methods quantifying related data might be available (doi:10.1594/PANGAEA.855002).

title: Abundance and biomass of Arctic benthic species

description: While the Arctic may be an inhospitable environment at the surface, the benthos is teaming with life. Even though this wealth of life is known to exist, information on the presence of benthic species at a pan-Arctic scale is scarce. To address this shortfall, abundance and biomass data from eighteen studies spanning the Arctic (i.e. Alaska, Canada, Svalbard, and Russia) were collected and merged into a single dataset. The collected species records range from 1970 to 2017. Because the rates of sampling are not always available it should be inferred that the species can be considered to likely be present between the start and end dates provided. If the day of sampling is the first of the month, it is generally because only the year and month were provided. The methods of sampling included here are: photography, diving collection, Van Veen grab, multinet, trawl, and sediment core. Species records taken along a transect are given with the minimum and maximum depths. The taxonomies provided are based on data from World Register of Marine Species website (WORMS). Biomass is given in gram ash free dry weight (AFDW) per square meter, carbon (C) gram per square meter, or gram wet weight (ww) per square meter. Abundance is given in number of individuals per square meter. Standard deviations for all measurements are given in the same units.

title: Plant height along the plant diversity gradient in the Jena Experiment (Main Experiment, year 2007)

description: This data set contains measurements of plant height: vegetative height (heighest leaf) and regenerative height (heighest flower) in 2007 from the Main Experiment plots of a large grassland biodiversity experiment (the Jena Experiment; see further details below). In the Main Experiment, 82 grassland plots of 20 x 20 m were established from a pool of 60 species belonging to four functional groups (grasses, legumes, tall and small herbs). In May 2002, varying numbers of plant species from this species pool were sown into the plots to create a gradient of plant species richness (1, 2, 4, 8, 16 and 60 species) and functional richness (1, 2, 3, 4 functional groups). Plots were maintained by bi-annual weeding and mowing. In 2007, plant height was recorded twice a year just before biomass harvest (during peak standing biomass in late May and in late August). For target plant individuals at 10 points separated by 1 m each along a transect in the central area in the plots, vegetative height (heighest leaf) and regenerative height (heighest flower) were measured as standing height (without stretching the plant). In 2007, also the plots of the management experiment, that altered mowing frequency and fertilized subplots (see further details below) were sampled by measuring vegatation height five times, every 0.5m on a 3m transekt along the side of the management plots. Provided are the individual measurements and the mean over the measured plants.

Empty cells represent missing values that result from the design of the experiment when the respective value does not occur and could thus not be measured.

title: Bulk density from the Jena Experiment (Main Experiment, year 2006)

description: This data set contains measurements of soil bulk density in different depth layers. Data presented here is from the Main Experiment plots of a large grassland biodiversity experiment (the Jena Experiment; see further details below). In the main experiment, 82 grassland plots of 20 x 20 m were established from a pool of 60 species belonging to four functional groups (grasses, legumes, tall and small herbs). In May 2002, varying numbers of plant species from this species pool were sown into the plots to create a gradient of plant species richness (1, 2, 4, 8, 16 and 60 species) and functional richness (1, 2, 3, 4 functional groups). Plots were maintained in general by bi-annual weeding and mowing. Since 2010, plot size was reduced to 5 x 6 m and plots were weeded three times per year.Soil bulk density was determined in spring from undisturbed soil samples to a depth of 30 cm. Three soil cores per plot were taken with a split tube sampler with an inner diameter of 4.8 cm and separated in depth increments of five cm. The bulk material was passed through a sieve with 2 mm mesh size, dried to constant weight at 40 °C and subsequently weighed to calculate the density.Paired sampling was chosen to avoid additional spatial variability (Lal et al., 2000), which means that three of the five sampling locations of 2002 bulk density measurement that were in the core area of the plots were chosen for the repeated sampling. The spatial distance of the paired soil samples were less than 30 cm.
description: The main experiment on the field site of the Jena Experiment comprises a split-plot design in which additional treatments (e.g. no weeding allowing for invasion of other species, or application of fertilizer) have been applied to subplots along the outer margin of the plots (see Treatment description in the section "further details"). While in this dataset only data from the core area (mown and weeding of all none-sown species twice a year, no additional treatments) is reported, all potential treatments are listed as the first parameters in the data file to guarantee compatibility with other datasets that include different treatments. There are two types of missing values contained in the dataset. Empty cells represent missing values that result from the design of the experiment when the respective value does not occur and could thus not be measured. For example, in the columns of species-specific biomass cells are left blank, when the species was not sown into the respective plot. Missing values that resulted from methodological problems, sampling errors, or lost samples/data are marked with "-9999".This dataset is part of a collection of measurements of physical and chemical soil properties in the Jena Experiment. Similar data from other experiments (e.g. Main Experiment, Dominance Experiment; see details above), other years, or other methods quantifying related data might be available (https://doi.pangaea.de/10.1594/PANGAEA.885439).

title: Carbon and nitrogen concentrations in plants (Main Experiment, year 2009)

description: This data set contains measurements of carbon and nitrogen concentrations in aboveground plant biomass. Data presented here is from the Main Experiment plots of a large grassland biodiversity experiment (the Jena Experiment; see further details below). In the main experiment, 82 grassland plots of 20 x 20 m were established from a pool of 60 species belonging to four functional groups (grasses, legumes, tall and small herbs). In May 2002, varying numbers of plant species from this species pool were sown into the plots to create a gradient of plant species richness (1, 2, 4, 8, 16 and 60 species) and functional richness (1, 2, 3, 4 functional groups). Plots were maintained in general by bi-annual weeding and mowing. Since 2010, plot size was reduced to 5 x 6 m and plots were weeded three times per year.Aboveground plant biomass was harvested once in May at estimated peak standing biomass before mowing. Plants were clipped at 3 cm above ground level in three rectangles of 20 x 50 cm size per plot. All material was sorted to species, weeds and rest (dead). Samples were dried at 70 °C for at least 48 h and weeds and rest were thrown away. All other material from one plot was combined to one sample and cut up with an analysis mill (Kinematica, Littau, Schweiz). A small subsample of this material was milled to fine powder in a ball-mill (Retsch MM 400). From the milled material max. 5 mg were weighed in for CN analysis. Carbon and nitrogen concentrations of this subsample were then determined with an elemental analyzer (Vario EL III, Elementar, Germany).

title: Dissolved organic carbon in soil solution of the Jena Experiment (Main Experiment, year 2002)

description: This data set contains measurements of dissolved organic carbon in samples of soil water collected from the main experiment plots of a large grassland biodiversity experiment (the Jena Experiment; see further details below). In the main experiment, 82 grassland plots of 20 x 20 m were established from a pool of 60 species belonging to four functional groups (grasses, legumes, tall and small herbs). In May 2002, varying numbers of plant species from this species pool were sown into the plots to create a gradient of plant species richness (1, 2, 4, 8, 16 and 60 species) and functional richness (1, 2, 3, 4 functional groups). Plots were maintained by bi-annual weeding and mowing. In April 2002 glass suction plates with a diameter of 12 cm, 1 cm thickness and a pore size of 1–1.6 mm (UMS GmbH, Munich, Germany) were installed in depths of 10, 20, 30 and 60 cm to collect soil solution. The sampling bottles were continuously evacuated to a negative pressure between 50 and 350 mbar, such that the suction pressure was about 50 mbar above the actual soil water tension. Thus, only the soil leachate was collected. Cumulative soil solution was sampled biweekly and analyzed for dissolved organic carbon concentration by a high TOC elemental analyzer (Elementar Analysensysteme GmbH, Hanau, Germany). Samples were analyzed as soon as possible and stored at 4°C if necessary. Often in summer, no free soil solution was available for collection, especially in the upper soil layers. Annual mean values of measured biweekly concentrations of dissolved organic carbon are provided.
description: During summer month soil frequently dries out so that no soil pore water can be collected. Consequently, in these periods no DOC concentrations can be determined and these periods do not contribute to the reported annual means of DOC concentrations. Only in block 2 suction plates were installed in all four depth layers. Suction plates in 30 centimeter depth were installed in block 1, 2, and 3 in 2002. In 2005, additional suctions plates were installed in 20 centimeter depth in block 1, 2, and 3. In block 4, no samples are available because no plates were installed.There are two types of missing values contained in the dataset. Empty cells represent missing values that result from the design of the experiment when the respective value does not occur and thus cannot be measured. Missing values that resulted from methodological problems, sampling errors, or lost samples/data are marked with "-9999".In addition to measurement of dissolved organic carbon in soil solution, measurements of soil carbon (organic, inorganic, and total) determined from dried soil samples are available.This datasets is part of a time series of soil carbon measurements in the Main Experiment since 2002 (doi:10.1594/PANGAEA.848946).
