Sponge Larval Settlement and Gene Expression Under Condensate Oil Exposure

Sponge larval settlement data, differential gene expression data, and microbial amplicon sequence variant data from an experiment on Phyllospongia foliascens. Larvae were exposed to six dilutions of a water accommodated fraction of partially weathered condensate oil for 24 hours. The data is associated with a 2024 research publication and raw sequencing data is available in the NCBI Sequence Read Archive.

Use Cases

• Modeling dose-response relationships for larval settlement based on oil exposure concentrations.
• Identifying biomarker genes for hydrocarbon stress in sponge larvae using differential expression data.
• Analyzing shifts in larval-associated microbial communities under oil exposure using ASV data.
• Correlating molecular responses with phenotypic outcomes like settlement success.

Strengths

• Data is linked to a specific, peer-reviewed 2024 research publication (Luter et al., 2024).
• Chemical characterization of the oil exposure medium is detailed in a separate, cited study (Negri et al., 2021).
• Raw sequencing data is publicly archived under NCBI BioProject PRJNA1012550.
• Experimental design includes a gradient of six treatment dilutions from 0 to 100%.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the study of the common Indo-Pacific sponge species.
