Supplementary file 1_Mating portfolio and neutral mechanisms are primary causes of genet-r

935 Spartina alterniflora stems were sampled from ten patches in a natural salt marsh and genotyped with ten microsatellite loci. The data includes 223 multilocus lineage genets (MLLs) and their ramet distributions, collected to study clonal patterns along environmental gradients. The dataset was authored by Jewel Tomasula and last updated on April 30, 2026.

Use Cases

• Modeling random sampling mechanisms for ramet distributions based on heterogeneous patch data.
• Analyzing spatial aggregation and interspersion of ramets within genets based on vegetative expansion patterns.
• Investigating genetic structure and mating systems based on excess homozygosity and low genetic differentiation.
• Testing hypotheses about neutral mechanisms versus environmental selection shaping genet-ramet frequencies.

Strengths

• 935 sampled stems provide a substantial sample size for genetic analysis.
• Ten microsatellite loci were used, providing high exclusion probabilities for genotype identification.
• Sampling was conducted on a 1-meter grid transect across natural environmental gradients, capturing spatial context.
• The dataset is licensed under CC-BY-4.0, permitting open reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The data file is a 3.1 MB DOCX, which may require format conversion for analysis.
