Bacterial Community Profiles Across a Karst Landscape in Switzerland

A 2026 study by Anusha Priya Singh profiles bacterial communities across interconnected environments in a peri-alpine karst landscape draining into Lake Thun, Switzerland. The dataset contains 16S rRNA gene sequences from soils, sediments, surface and subsurface waters, and distinct lake strata. Environment type explained 19% of the total variation in bacterial communities.

Use Cases

• Analyzing transitional gradients in bacterial communities along the terrestrial-aquatic interface based on environment type.
• Identifying core microbiome taxa shared between surface and subsurface hydrological networks based on reported 63.8%–84.6% overlap.
• Studying metabolic assemblages associated with specific environments like peat soils or lake strata based on co-occurrence network modules.
• Investigating redox-driven processes across environments based on modules linked to nitrogen compound, metal, and methane oxidation.

Strengths

• High microbial diversity reported for all environments except the lake.
• Clear statistical result showing environment type explains 19% of total community variation.
• Strong overlap quantified between surface and subsurface hydrological networks (63.8%–84.6% shared core taxa).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The 1.9 MB file size suggests a relatively small dataset.
