Glyphosate Herbicide Effects on Ant Mortality and Larval Development

Marius Pohl's dataset from 2026 documents lethal and sublethal effects of oral glyphosate-based herbicide exposure on two ant species, Camponotus maculatus and Cardiocondyla obscurior. It contains experimental results from 21-day exposure tests at field-relevant concentrations ranging from 0.5% to 10% GBH. The data supports research on non-target arthropod ecotoxicity.

Use Cases

• Analyze dose-dependent mortality rates in Cardiocondyla obscurior workers exposed to varying GBH concentrations.
• Model the relationship between GBH concentration and larval developmental impairments, such as pupal malformation rates up to 32% in Camponotus maculatus.
• Compare avoidance thresholds (e.g., 7.2 g/L for C. maculatus, 3.6 g/L for C. obscurior) with subsequent mortality and sublethal effects.
• Investigate correlations between oral exposure levels and loss of phenotypic robustness in C. obscurior workers exposed during larval stage.

Strengths

• Data includes results for two distinct ant species, enabling comparative analysis.
• Tests conducted over a 21-day period at multiple field-relevant concentrations (0.5% to 10% GBH).

Limitations

• Dataset scale is small at 4.1 MB, suggesting limited row count or feature breadth.
• Specific sample sizes (e.g., number of colonies, workers, larvae) are not provided.
• Geographic origin of the ant species or test location is unknown.
