Botanical Taxidermy, a free science course on Tomo

Botanical Taxidermy

Preserve the lifelike three-dimensional form, cellular structure, and coloration of botanical specimens. Master desiccation kinetics, chemical replacement, tissue clearing, and museum-grade specimen conservation.

Like Duolingo, but for Botanical Taxidermy. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.

21 levels across 3 sections, about 42 minutes end to end, roughly 8 days at five minutes a day. It moves through Three-Dimensional Desiccation, Liquid Substitution and Clearing, and Archival Conservation and Specimen Display.

What you'll learn

Key ideas in Botanical Taxidermy

  • Direct contact with coarse granules creates localized point-load stress that crushes delicate petal lamina against rigid structural veins
  • A micro-mesh bedding distributes mechanical weight evenly across fragile venation while providing high surface-area contact for capillary moisture draw
  • Coarser granules placed higher in the container provide bulk moisture-absorbing capacity without transferring crushing point loads directly to the tissue
  • Internal stenting must be established before external wedges to prevent radial crushing of the petal tube
  • Sub-corolla wedges counteract downward gravitational sag as turgor pressure drops during early desiccation
  • Backfilling granular material around an unstaged corolla causes flaccid petals to fold inward or flatten against the container base
  • Autolytic polyphenol oxidases (PPOs) remain active at ambient room temperature, driving enzymatic browning as cellular membranes destabilize
  • Targeted moderate thermal escalation (40°C–50°C) accelerates water removal past the critical threshold of water activity needed for PPO activity before thermal degradation of pigments occurs
  • Cold or slow desiccation prolongs membrane breakdown in a hydrated state, allowing endogenous enzymes prolonged catalytic contact with vacuolar phenolics
  • Thick, waxy succulent cuticles create an impermeable barrier that traps internal moisture; as internal mesophyll shrinks, uneven water evacuation causes hydrostatic tension that shears the epidermis from the parenchymal core
  • Micro-perforations through the cuticle bypass the diffusion bottleneck, establishing controlled egress channels that match moisture escape to structural parenchymal retreat
  • Excessive compressive weight crushes internal water-storage parenchyma before desiccative moisture transfer can occur
  • Anhydrous botanical specimens readily re-absorb atmospheric moisture via hygroscopic cell wall polymers, causing cellular distortion, pigment leaching, or mold
  • Paraloid B-72 in fast-evaporating acetone forms a tough, moisture-impermeable barrier that is fully reversible with solvents and does not rehydrate cellulose fibers during application
  • Solvent-sensitive structures like glandular trichomes dissolve under ketone or aromatic solvents, requiring an alcohol- or water-tolerant alternative like Klucel to prevent lipid stripping
  • Ultra-rapid quenching (such as LN2 slush) maximizes nucleation frequency, yielding ice microcrystals small enough to avoid tearing primary cell walls or fracturing plasma membranes
