Abstract

fetched live from OpenAlex

We present a synthesis of diet information for all 78 species of extant African Bovidae (excluding goats and sheep), based on an extensive survey of the literature. We compiled data on food types (percentages of fruits, dicotelydons, and monocotyledons), seasonal and geographic variability, and body mass. Information reported in the literature was evaluated critically to assess its reliability. We performed cluster analyses to identify 6 discrete dietary strategies: frugivores, browsers, generalists, browser–grazer intermediates, variable grazers, and obligate grazers. We identified a positive correlation between an increase in the proportion of monocots in the diet and body mass, and a negative correlation between increases in proportions of dicots and fruits and body mass. We found some degree of correspondence between taxonomic groupings and dietary strategies. Species in the tribes Alcelaphini, Hippotragini, and Reduncini have high proportions of monocots in their diets. Cephalophini, with the exception of Sylvicapra, are frugivores. Tragelaphini and Neotragini, with the exception of Ourebia, have diets that include high proportions of dicots.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
