AnAge body mass is the column Body mass (g), which is present, and offspring number is Litter/Clutch size. Spearman correlations use log10 of both. Amniotes are birds, mammals, and reptiles. Fishes are reported with the pre-registered class rule. PanTHERIA mammals are the replication. OLS slopes are stored and do not set the verdict. https://w3id.org/delphi/resource/assessment/aristotle-ga01-22--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-ga01-22--claim-test http://www.w3.org/2000/01/rdf-schema#comment Measured: -0.3480463134303726 Spearman rho of log10 litter or clutch size on log10 body mass, AnAge amniotes (n = 540, two-sided p = 8.016e-17). Interpretation: Few young and many young are read as litter or clutch size, the number of offspring in one reproductive event, not as lifetime fecundity and not as offspring mass. Large and small are adult body mass. Animals generally is tested first in amniotes, the classes AnAge covers densely, and the fish split is pre-registered because a pattern that reverses in fishes would not be a pattern for animals generally. Phylogenetic non-independence is only partly handled, by requiring the sign inside classes rather than by a phylogenetic regression. No tree is part of this registration. https://w3id.org/delphi/resource/assessment/aristotle-ga01-22--claim-test http://www.w3.org/2000/01/rdf-schema#label Claim test of aristotle-ga01-22: supports, confidence 0.55 https://w3id.org/delphi/resource/assessment/aristotle-ga01-22--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-ga01-22/result.json https://w3id.org/delphi/resource/assessment/aristotle-ga01-22--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-ga01-22--claim-test https://w3id.org/delphi/ontology/admissibleDatasets Published species-level tables of adult body mass and litter or clutch size, compiled independently of Aristotle.

A mammal-heavy table can dominate the pooled correlation; the class-wise rule is there for that reason. https://w3id.org/delphi/resource/assessment/aristotle-ga01-22--claim-test https://w3id.org/delphi/ontology/evidenceAgainst Body mass (g) is the AnAge mass paired with metabolic-rate rows. Adult weight (g) was not substituted, because the registration names Body mass (g) when that column is present. https://w3id.org/delphi/resource/assessment/aristotle-ga01-22--claim-test https://w3id.org/delphi/ontology/evidenceAgainst Fishes are present (961 rows), but Body mass (g) together with litter or clutch size is filled for 0 of them, so the fish pattern is absent. Adult weight (g) together with litter is filled for 64 fish and was not used. Birds with both registered fields are not a negative class. The pooled amniote correlation is carried by the classes that meet the negative cut, principally mammals. https://w3id.org/delphi/resource/assessment/aristotle-ga01-22--claim-test https://w3id.org/delphi/ontology/evidenceAgainst Spearman correlation is not a phylogenetic contrast. Related species are not independent observations. https://w3id.org/delphi/resource/assessment/aristotle-ga01-22--claim-test https://w3id.org/delphi/ontology/evidenceAgainst Species are not phylogenetically independent. The class split is the only control the registration allowed. https://w3id.org/delphi/resource/assessment/aristotle-ga01-22--claim-test https://w3id.org/delphi/ontology/expectedObservation Across birds, mammals, and reptiles, log litter or clutch size falls with log adult body mass with Spearman rho at most -0.20, and fishes do not show a clear rise of offspring number with body mass. https://w3id.org/delphi/resource/assessment/aristotle-ga01-22--claim-test https://w3id.org/delphi/ontology/failCriterion Pre-registered. Verdict 'refutes' if the amniote pattern is 'positive'. Verdict 'mixed' if the amniote pattern is 'flat', or if it is 'negative' and the fish pattern is 'positive', or if it is 'negative' and two or more amniote classes with n >= 30 have rho > 0 and p < 0.05. PanTHERIA mammals (adult body mass in grams > 0 and litter size > 0; -999 and non-positive values are missing) are a replication: if that file matches its checksum, n >= 100, rho > 0, and p < 0.01, a negative amniote pattern is downgraded to 'mixed'. Verdict 'inconclusive' with reason 'underpowered' if fewer than 100 amniotes have both fields, and with reason 'data-unavailable' if the AnAge checksum fails or the mass or litter column cannot be identified. A failed PanTHERIA checksum drops the replication and does not by itself make the test inconclusive. Annual fecundity is not the verdict quantity: the sentence says few young, read as litter or clutch size per reproductive event. https://w3id.org/delphi/resource/assessment/aristotle-ga01-22--claim-test https://w3id.org/delphi/ontology/hasConfidence 0.55 https://w3id.org/delphi/resource/assessment/aristotle-ga01-22--claim-test https://w3id.org/delphi/ontology/hasEvidence https://w3id.org/delphi/resource/evidence/aristotle-ga01-22--claim-test--dataset-1 https://w3id.org/delphi/resource/assessment/aristotle-ga01-22--claim-test https://w3id.org/delphi/ontology/hasEvidence https://w3id.org/delphi/resource/evidence/aristotle-ga01-22--claim-test--dataset-2 https://w3id.org/delphi/resource/assessment/aristotle-ga01-22--claim-test https://w3id.org/delphi/ontology/hasVerdict supports https://w3id.org/delphi/resource/assessment/aristotle-ga01-22--claim-test https://w3id.org/delphi/ontology/hypothesis If large animals have few young and small animals have many, litter or clutch size declines with adult body mass across amniotes, and does not rise with body mass in fishes. https://w3id.org/delphi/resource/assessment/aristotle-ga01-22--claim-test https://w3id.org/delphi/ontology/inferenceMethod Spearman rank correlation of log10 body mass with log10 litter or clutch size, two-sided, effect-size cuts at -0.20 and +0.20, with class-wise and fish splits as pre-registered. Ordinary least-squares slope is reported and is not the verdict. https://w3id.org/delphi/resource/assessment/aristotle-ga01-22--claim-test https://w3id.org/delphi/ontology/passCriterion Pre-registered. From AnAge build 15, species with body mass in grams > 0 and litter or clutch size > 0. Body mass is the column whose header is 'Body mass (g)' if present, otherwise 'Adult weight (g)'. Litter or clutch size is the column whose header contains 'Litter' and 'Clutch'. Amniote classes, matched on the lowercased class field, are mammalia, mammals, mammal, aves, birds, bird, reptilia, reptiles, reptile. Let rho_A and p_A be the Spearman correlation of log10(body mass) with log10(litter or clutch size) on the amniote rows. The amniote pattern is 'negative' if the number of amniote species is at least 100, rho_A <= -0.20, and p_A < 0.01. It is 'positive' if n >= 100, rho_A >= 0.20, and p_A < 0.01. Otherwise, if n >= 100, it is 'flat'. A fish class is one whose lowercased name is actinopterygii, chondrichthyes, osteichthyes, teleostei, sarcopterygii, cephalaspidomorphi, myxini, agnatha, chondrostei, holostei, fish, fishes, or pisces, or whose name contains 'fish', 'shark', or 'ray'. The fish pattern uses the same rho cuts when at least 30 fish species qualify, and is 'absent' otherwise. The claim is supported only if the amniote pattern is 'negative', the fish pattern is not 'positive', fewer than two amniote classes with at least 30 species have rho > 0 and p < 0.05, and the PanTHERIA mammal replication is not a significant positive (defined in the fail criterion). https://w3id.org/delphi/resource/assessment/aristotle-ga01-22--claim-test https://w3id.org/delphi/ontology/preregistered false https://w3id.org/delphi/resource/claim/aristotle-ga01-22 https://w3id.org/delphi/ontology/hasAssessment https://w3id.org/delphi/resource/assessment/aristotle-ga01-22--claim-test https://w3id.org/delphi/resource/evidence/aristotle-ga01-22--claim-test--dataset-1 http://purl.org/dc/terms/description body mass and litter or clutch size by class https://w3id.org/delphi/resource/evidence/aristotle-ga01-22--claim-test--dataset-1 http://purl.org/dc/terms/license CC BY 3.0 https://w3id.org/delphi/resource/evidence/aristotle-ga01-22--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-ga01-22--claim-test--dataset-1 http://www.w3.org/2000/01/rdf-schema#label Dataset: AnAge: The Animal Ageing and Longevity Database, build 15 https://w3id.org/delphi/resource/evidence/aristotle-ga01-22--claim-test--dataset-1 http://www.w3.org/ns/prov#atLocation https://genomics.senescence.info/species/dataset.zip https://w3id.org/delphi/resource/evidence/aristotle-ga01-22--claim-test--dataset-1 http://www.w3.org/ns/prov#wasDerivedFrom https://genomics.senescence.info/species/ https://w3id.org/delphi/resource/evidence/aristotle-ga01-22--claim-test--dataset-1 https://w3id.org/delphi/ontology/hasChecksum sha256:e3ddb66e32e973a79932859ba53013e8f60d957c6ec01c6eb573e3ea3018d630 https://w3id.org/delphi/resource/evidence/aristotle-ga01-22--claim-test--dataset-2 http://purl.org/dc/terms/description mammal adult body mass and litter size replication https://w3id.org/delphi/resource/evidence/aristotle-ga01-22--claim-test--dataset-2 http://purl.org/dc/terms/license Ecological Archives;
