Spider Fitness Costs from Wolbachia Feminization, 14.5 KB

A 14.5 KB Excel dataset by Jordyn D. Robinson, last updated April 30, 2026. It contains experimental results measuring fitness costs associated with a feminizing Wolbachia endosymbiont in the spider Mermessus fradeorum. The data likely includes fecundity and offspring development metrics from spiders with various symbiont co-infections.

Use Cases

• Quantify host fitness costs based on egg count and development failure rates described in the study
• Analyze the impact of specific symbiont co-infections on female fecundity
• Model the population dynamics of feminizing symbionts in hosts with XX/X0 sex determination
• Compare fitness outcomes between eggmasses infected with the feminizing Wolbachia versus other symbiotypes

Strengths

• Specific fitness cost metrics are provided: eggmasses with the feminizing Wolbachia had 16% fewer eggs
• Clear experimental comparison: 20% egg development failure with the feminizer versus 4% in other symbiotypes
• Dataset is shared under a permissive CC-BY-4.0 license

Limitations

• Row count is unknown, which may limit suitability assessment
• Column-level documentation is absent; field semantics must be inferred after download
• The dataset is very small at 14.5 KB, indicating limited scope
