A seasonal contrast requires a mass column and at least two season labels, or months at least three months apart. Breeding and non-breeding medians are taken only from labels that say so. Almost indiscernible is a ratio of at most 0.10. One date is not assigned to a season. https://w3id.org/delphi/resource/assessment/aristotle-ga01-09--claim-test http://www.w3.org/1999/02/22-rdf-syntax-ns#type https://w3id.org/delphi/ontology/Assessment https://w3id.org/delphi/resource/assessment/aristotle-ga01-09--claim-test http://www.w3.org/2000/01/rdf-schema#comment Measured: null median across species of non-breeding testis mass divided by breeding testis mass (n = 0, a ratio is computed only when both seasons have at least three birds and the labels name the seasons). Interpretation: Much enlarged at copulation and almost indiscernible afterwards is a within-species seasonal contrast, not a comparison of testis size across species. Almost indiscernible is operationalized as non-breeding mass at most 10 percent of breeding mass. A shrink that leaves half the mass is still a visible organ. The file is a common-garden gonad table; if it has one date, it does not contain this contrast. https://w3id.org/delphi/resource/assessment/aristotle-ga01-09--claim-test http://www.w3.org/2000/01/rdf-schema#label Claim test of aristotle-ga01-09: inconclusive, confidence 0.75 https://w3id.org/delphi/resource/assessment/aristotle-ga01-09--claim-test http://www.w3.org/2000/01/rdf-schema#seeAlso https://github.com/fractastical/delphisci/blob/bf2af6ee0a84e23ffa6414ad7a0a50a8c276506e/test-data/claim-tests/aristotle-biology/aristotle-ga01-09/result.json https://w3id.org/delphi/resource/assessment/aristotle-ga01-09--claim-test http://www.w3.org/ns/prov#wasAttributedTo https://w3id.org/delphi/resource/agent/delphisci-claim-tester-grok-4-7 https://w3id.org/delphi/resource/assessment/aristotle-ga01-09--claim-test https://w3id.org/delphi/ontology/admissibleDatasets A checksummed table of testis mass with a breeding contrast for the same species.

The file is Common_garden_gonads_testis.csv from Dryad doi:10.5061/dryad.zkh1893k8, API file id 3746720, 1983 bytes, download https://datadryad.org/downloads/file_stream/3746720. A mass column has a header matching testis and (mass or weight or size). A season column has a header matching season, breeding, month, or date. Breeding and non-breeding are two distinct labels, or two months at least three months apart. For each species, the ratio is the median non-breeding mass divided by the median breeding mass. Almost indiscernible means that ratio is at most 0.10. Support, confidence 0.70, only if at least five species each have at least three birds in each season and every one of those ratios is at most 0.10, and each breeding median is greater than the non-breeding median. https://w3id.org/delphi/resource/assessment/aristotle-ga01-09--claim-test https://w3id.org/delphi/ontology/preregistered false https://w3id.org/delphi/resource/claim/aristotle-ga01-09 https://w3id.org/delphi/ontology/hasAssessment https://w3id.org/delphi/resource/assessment/aristotle-ga01-09--claim-test https://w3id.org/delphi/resource/evidence/aristotle-ga01-09--claim-test--dataset-1 http://purl.org/dc/terms/description testis mass by season https://w3id.org/delphi/resource/evidence/aristotle-ga01-09--claim-test--dataset-1 http://purl.org/dc/terms/license CC0-1.0 https://w3id.org/delphi/resource/evidence/aristotle-ga01-09--claim-test--dataset-1 http://www.w3.org/1999/02/22-rdf-syntax-ns#type https://w3id.org/delphi/ontology/EvidenceItem https://w3id.org/delphi/resource/evidence/aristotle-ga01-09--claim-test--dataset-1 http://www.w3.org/2000/01/rdf-schema#label Dataset: Common-garden testis measurements https://w3id.org/delphi/resource/evidence/aristotle-ga01-09--claim-test--dataset-1 http://www.w3.org/ns/prov#atLocation https://datadryad.org/downloads/file_stream/3746720 https://w3id.org/delphi/resource/evidence/aristotle-ga01-09--claim-test--dataset-1 http://www.w3.org/ns/prov#wasDerivedFrom https://datadryad.org/dataset/doi:10.5061/dryad.zkh1893k8 https://w3id.org/delphi/resource/evidence/aristotle-ga01-09--claim-test--dataset-1 https://w3id.org/delphi/ontology/hasChecksum sha256:d6b327bea7558986f9ec9ca43d7db0698e803586eea14eb06fd0efb629b6eb1b https://w3id.org/np/RAYzQDv8Rv7zahP9kgakwwhHgTZdFLZezI99NC49zt77U/provenance https://w3id.org/delphi/resource/agent/delphisci-claim-tester-grok-4-7 http://www.w3.org/1999/02/22-rdf-syntax-ns#type http://www.w3.org/ns/prov#SoftwareAgent https://w3id.org/delphi/resource/agent/delphisci-claim-tester-grok-4-7 http://www.w3.org/2000/01/rdf-schema#label delphisci claim tester (Grok 4.7;
