Daphnia Galeata Phototactic Behavior Under Artificial Light at Night

Lapiere et al. (submitted to Belgian Journal of Zoology) provides experimental data on the phototactic behavior of the freshwater zooplankton Daphnia galeata under artificial light at night (ALAN). The dataset includes results from 67 individually assayed animals tested at four time points across a 24-hour cycle under control and ALAN conditions. It was authored by Eli Thoré and last updated on figshare in May 2026.

Use Cases

• Modeling size-dependent vertical positioning in zooplankton based on phototactic behavior.
• Analyzing diel modulation of phototactic responses in freshwater species.
• Investigating the acute effects of low-intensity artificial light at night on aquatic invertebrate behavior.
• Studying the relationship between individual size and activity levels (zone-crossing) in Daphnia.

Strengths

• Includes data from 67 individually assayed Daphnia galeata, allowing for individual-level analysis.
• Experimental design tests animals at four distinct time points across a 24-hour diel cycle.
• Data is available in multiple accessible formats (PDF, XLSX, TXT).
• Released under a permissive CC-BY-4.0 license for reuse.

Limitations

• Row count and column-level documentation are unknown, which may limit suitability assessment.
• The dataset is small in scale at 407.0 KB, indicating a limited experimental scope.
• Description metadata is limited; actual data quality and structure require manual inspection after download.
