QIONG YANG's dataset explores the relationship between the density of the obligate bacterium Buchnera aphidicola and host fitness in the bird cherry–oat aphid, Rhopalosiphum padi. The data includes measurements of Buchnera density, body length, and fitness metrics like fecundity and intrinsic rate of increase for hundreds of individuals across experiments and generations. It was last updated on 2026-04 17 and is available as an 88.9 KB XLSX file under a CC-BY-4.0 license.
Use Cases
- Modeling phenotypic selection on symbiont density based on the Lande–Arnold framework described.
- Analyzing the relationship between Buchnera density and aphid fitness metrics like fecundity.
- Investigating the differential selection pressure on symbiont density between apterous and alate aphid morphs.
- Studying the recovery of symbiont density and host fitness after antibiotic treatments like tetracycline.
Strengths
- Data includes measurements for hundreds of individual aphids across experiments and generations.
- Fitness is measured using multiple metrics: fecundity and intrinsic rate of increase.
- Applies the Lande–Arnold phenotypic selection framework to estimate directional, quadratic, and correlational selection.
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 small at 88.9 KB, indicating a limited scope.
