Effects of Abiotic Stressors on Infaunal Burrowing and Associated Sediment Characteristics

Laboratory experiment data examines the effects of temperature, salinity, and food availability on the burrowing activity of the polychaete Capitella sp. 1. The dataset includes measurements of burrow depth, area of activity, and associated sediment chemistry using pH and O2 fluorosensors. Results show burrowing behavior and sediment solute exchange are affected by environmental stressors.

Use Cases

• Modeling infaunal behavioral responses to temperature stress based on burrowing depth measurements
• Analyzing the impact of salinity gradients on bioturbation activity based on burrowing area data
• Studying the relationship between nutrient enrichment and sediment reworking based on food availability treatments
• Investigating links between burrowing activity and sediment-water solute exchange based on fluorosensor data

Strengths

• Examines three distinct abiotic stressors: temperature (15, 21, and 32°C), salinity (16, 22, 28, and 34), and food availability (low, moderate, high)
• Includes direct physiological and behavioral outcomes, such as worm death at 32°C and significant differences in burrow depth across treatments
• Links organism behavior to ecosystem function by measuring sediment chemistry with pH and O2 fluorosensors

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Freshness should be verified; last updated metadata indicates 2026-06-04
