Effects of Abiotic Stressors on Infaunal Burrowing and Sediment Chemistry

Geoscience Australia Data provides a dataset from laboratory experiments examining the effects of temperature, salinity, and food availability on the burrowing activity of the polychaete Capitella sp. 1. The data includes measurements of burrow depth, area of activity, and associated sediment chemistry using pH and O2 fluorosensors. The dataset was last updated on 2026-04-30.

Use Cases

• Modeling the impact of temperature stress on infaunal behavior based on the described experimental temperature treatments (15, 21, 32°C).
• Analyzing the relationship between food availability and burrowing depth based on the low, moderate, and high food treatments.
• Investigating solute exchange across the sediment-water interface based on the fluorosensor measurements of pH and O2.
• Assessing community and ecosystem responses to environmental change based on the described link between infaunal activity and sediment characteristics.

Strengths

• Data is derived from controlled laboratory experiments with specific abiotic treatments: three temperatures, four salinities, and three food availability levels.
• Includes direct physiological and behavioral outcomes, such as burrowing depth, area of activity, and mortality at 32°C.
• Integrates biological behavior with chemical measurements using pH and O2 fluorosensors.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Data may reflect methodological bias inherent to laboratory experiments rather than field conditions.
