Abstract

fetched live from OpenAlex

Many taxa of lizards bear transversely enlarged subdigital scales that are often a source of systematic characters.Among gekkonid and polychrotid lizards, elaborations of such scales, called lamellae and scansors, are employed in adhesive locomotion (Colette, 1961;Hiller, 1968;Russell, 1975).Subdigital lamellae and scansors are derivatives of scales, the form, shape and number of which are thought to re ect function (Russell, 1981) as well as indicate patterns of relationship (Couper et al.; 1993I Raxworthy andNussbaum, 1993;Grismer et al.;1994/.While lamellae in the loose sense encompass all subdigital scales that are transversely enlarged, they can be divided into two subsets ( g. 1): scansors, the distal lamellae most closely involved in adhesion and therefore occurring on the hyperextensible portion of a digit (Russell, 1981(Russell, , 1986)); and basal lamellae, which differ morphologically from scansors (Russell, 1981), and are situated more proximally.Scale patterns in squamates are generally regarded as being genetically determined and discrete (Hecht, 1952).Counts of total lamellae feature in both systematic (Grismer et al.; 1994, etc.) and functional (Hecht, 1952; Peterson, 1983a, b; Mayer in Losos, 1990;Glossip and Losos, 1997) studies.Numbers of total lamellae vary both within and between digits and, as a consequence, most authors choose to count these structures on a smaller set of digits, on the assumption

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.
