Marine Consumer Niche Differentiation with Amino Acid δ¹³C Fingerprinting

Amino acid carbon isotope (δ¹³C) fingerprints characterize trophic niches in marine food webs. The data likely contains measurements from six functional groups and ten species, including herring and sprat, across four Baltic Sea regions. The dataset was produced by Thomas Larsen of the Max Planck Institute for the Science of Human History.

Use Cases

• Differentiating trophic niches among marine functional groups based on δ¹³AA fingerprinting.
• Investigating regional biochemical differences in zooplanktivorous fish based on migratory marker potential.
• Comparing the resolution of bulk stable isotope data against amino acid fingerprinting for niche analysis.

Strengths

• Data includes six distinct functional groups and ten individual species.
• Samples cover four different Baltic Sea regions with varying biochemical conditions.
• Methodology compares δ¹³AA fingerprints directly with bulk C and N isotope data.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
