The Massasauga dataset is the only source with complete, directly comparable quantitative values for all requested thermal biology metrics, so it anchors every graph below. Reported values: mean body temperature Tb = 31.7 Β± 0.3Β°C from a thermal gradient; the set range Tset = 30.0β33.6Β°C (25thβ75th percentile); operative environmental temperature Te fell below Tset in 99% of observations (9142/9215) with a mean TeβTset deviation of 10.7Β°C; thermoregulation accuracy db = 6.9Β°C (day 6.3, night 9.6); effectiveness de = 3.3Β°C (day 3.4, night 2.7); and %MaxE = 63.9% (day 65.5%, night 57.1%) from 34 snakes.
Interpretation: db exceeds de by ~3.6Β°C, meaning snakes closed about half the gap between their Te and Tset β effective but imperfect thermoregulation. Night db is larger (9.6Β°C) yet night de is smaller (2.7Β°C), so nocturnal gains come disproportionately from a colder, more challenging baseline rather than superior behavioral precision.
The Hoplocephalus stephensii study provides the contrast metric set: field Tb 24.0Β°C, lab Tset range 27.8β29.3Β°C, mean TbβTa β 3.5Β°C, and mean de β db β 0.19 β a far lower thermoregulatory gain than the Massasauga. Comparing the two makes the guide's metric framework concrete: a 'reluctant heliotherm' vs a boreal active thermoregulator.
Code plan (Python 3): structure the pipeline as (a) data ingestion from the user's guide tables into pandas; (b) validation of metric definitions (db = |TbβTe| deviation from Tset; de = deviation of Te from Tset; E = (deβdb)/de); (c) computation of E/Ex and %MaxE; (d) Plotly rendering (bar, box, scatter Tb vs Te, and a thermal-knowledge network via vis-network linking TbβTeβTsetβdbβdeβE). All values above are reported observations; the Hoplocephalus midpoint Tset is a BGPT-derived mean (27.8β29.3Β°C / 2 β 28.55Β°C), not a reported number.
