      <abstract>This soil and vegetation data were collected along a successional gradient at the Indiana Dunes National Park.  Soil samples were processed for standard soil chemistry, texture, and nutrients. DNA extracted from soil samples were analyzed for bacterial communities using 16S rRNA amplicon sequencing technique to understand the composition and distribution of these communities along the successional gradient. Soils samples were collected in 2015 and 2017. Vegetation data were collected only in 2017, as the vegetation was dormant in 2015. We collected the data to examine the relationships among soils, vegetation, and composition of the microbial communities along a dunal chronosequence. A dunal chronosequence is a series of coastal dunes that formed at different times thus a chrono-sequence. In such a sequence, the younger dunes are near the lakeshore and the older ones are inland. The raw metagenomic data can be accessed at the NCBI repository under the bioproject accession PRJNA658136.</abstract>

      <attraccr>The soil data was derived from chemical and physical analyses based on standardized protocols (conducted at A&amp;L Great Lakes Laboratories, Fort Wayne). Vegetation sampling involved two components, species identification and cover estimation. Cover estimate was based on using % cover squares (1, 2, and 5%) for estimation calibration. Plant identification was performed by a plant ecologist familiar with taxonomy.</attraccr>
    </attracc>
    <logic>The soil chemistry values are based on a 10 cm deep soil probe that was analyzed by  A&amp;L Great Lakes Laboratory in Fort Wayne, Indiana. Physical and chemical results were examined for acceptable range of values and detection capabilities.

        <procdesc>FIELD DATA COLLECTION

1) Arrived at the successional stage.
2) Selected a location that did not have any obvious human disturbance in that successional stage.
3) A half-meter square plot was placed at the sampling site.
4) Within the plot, the species and cover of the plant presence was recorded.
5) Percent bare ground, litter coverage and total vegetation cover were estimated.
6) Triplicate soil samples were taken near the center of the plot, after the litter cover was removed by displacing with a sterile tongue depressor. 15-ml centrifuge tubes were pushed into the soil to collect the sample and then capped. Tubes were placed in a cooler with ice for transport back to the lab.
7) Sub samples were used for 16S rRNA targeted metagenomic analysis.
8) Bulk soil samples for physical and chemical analysis were taken from the plot. A 1 cm diameter soil probe was pushed into the soil and the top 10 cm of the soil core were placed inside a bag. Multiple probes were taken, until a volume of approximately 236 ml was achieved.
The bulk soil samples were placed on ice in a cooler.

1) Centrifuge tubes with soil sample were stored in a freezer -20˚C until processed for DNA extraction.
2) Bulk soil samples were placed in walk-in freezer at -20˚C until shipping to A&amp;L labs for physical and chemical processing.
3) Plant community data were transcribed from data sheets into an Excel file.
4) When results from physical and chemical analysis were received from A&amp;L labs, the results were entered into the same Excel file.
5) Results in Excel file were scanned for errors and expected values.

Illumina 16S rRNA Gene Sequencing:

PCR-amplification of the 16S rRNA gene in water and sand DNA extracts was performed using V3-V4 region primers (343-forward TAC GGR AGG CAG CAG and 804-reverse CTA CCR GGG TAT CTA ATC C). PCR protocol and primers tags were following the manufacturer’s suggested step out protocol (Illumina, San Diego, CA). Reactions were carried out using ~10 ng of template DNA in Q5® High Fidelity DNA Polymerase 2X master mix (New England Biolabs). PCR amplicons were purified using AxyPrepMag PCR clean-up kit (Axygen Scientific) and quantified using a Nanodrop 3000 fluorospectrophotometer after staining with the QuantiFluor dsDNA System (Promega). Amplicon were combined in equimolar amounts sequenced (2x250 paired end) on a MiSeq Illumina instrument at the Purdue Genomics core facilities.

16S rRNA gene sequence analysis:

Sequences with primer tags removed and paired end reads merged (PANDAseq software), (Masella et al., 2012) were analyzed using the QIIME pipeline (version 1.9.1) (Caporaso et al., 2010). The options in QIIME chosen were “pick_open_otus” (Rideout et al., 2014), uclust (Edgar, 2010) for clustering, PyNAST (Caporaso et al., 2010) for sequence alignment, and RDP classifier (Wang et al., 2007) for taxonomic assignment using the Greengenes data set (version 13_5) (McDonald et al., 2012). Rarefied datasets (lowest number of reads among the samples being compared) were used for beta-diversity comparisons. Metrics tested included both phylogenetic Unifrac distances (weighted and un-weighted) (Lozupone et al., 2011) and non-phylogenetic distances (weighted Jaccard and Bray Curtis). Good’s coverage to assess completeness of OTU representation in each sample. Alpha-diversity measurements were used for richness and evenness (Shannon diversity), richness (ChaoI index, observed-species), Faith’s phylogenetic diversity (PD whole tree) and evenness (Simpson’s e).

          <udom>Contemporary = Active coastal dune systems where sand movement and stabilization are ongoing. This includes the beach, foredunes and secondary dune.

Recent = Active to forest to dune transition where stabilization is predominant.

Tolleston = Phase representing dunes that formed approximately 3 to 4 thousand years ago and are now stabilized. 

Calumet = Phase representing dunes that formed approximately 11,000 years ago and are now stabilized.

Glenwood =  Phase representing dunes that formed approximately 13,000 years ago and are now stabilized.

          <udom>Beach = Transition from the lake to the dune.

Foredune = First dune formed adjacent to the beach that parallels the beach and it's often dominated by marram grass because of active sand deposition and erosion.

Secondary dune = More stabilized dunes behind or inland the foredune that tends to be stabilized. Often dominated by little blue stem grass, but often interspersed with blowouts.

Woodland transition = Area behind secondary dunes where tree invasion is occurring. 

Woodland = Stabilized dune system dominated by black oak, where frequent fire maintains more open tree canopy.

Oak forest = Stabilized dune system dominated by black and white oak, with multilayer structure (shrubs, sapling, sub-canopy and canopy)
