Orchidarc studies the places where orchids physically meet the world: adhesive pollination structures, stigmatic soft materials, pollinator contact mechanics and threatened cloud-forest habitats. The research programme connects conservation biology with biomaterials, field ecology and documentary evidence.
The research section is organised around interfaces: pollinator attachment, stigma capture, material deformation and threatened habitats.
Comparative study of viscidia and related reproductive adhesives across orchid genera, combining FTIR-ATR spectroscopy, morphology and contact-area-aware mechanical testing.
Rheological and microscopy-based characterisation of orchid stigmatic secretions as hydrated matrix-cell biocomposites rather than simple floral fluids.
Open programme
Force, deformation and failure during pollinarium withdrawal. In Cattleya walkeriana, withdrawal rate selects the failure mode — and decides whether pollen is exported at all.
Field documentation, locality records, conservation assessments and species-level profiles for Mexican orchids, with emphasis on cloud-forest epiphytes and micro-endemic lineages.
A primary-study synthesis and diploid forward-time model linking paternal shares within orchid fruits to offspring retained after establishment and density regulation. Four matched paternity regimes separate the direct effect on resident male contribution from the more conditional effect on simulated neutral diversity.
The strongest version of Orchidarc research is not generic biomimicry. It treats orchid reproductive structures as real biological materials, then returns those measurements to conservation and pollination biology.
Habitat notes, photographic vouchers, GPS locality records and repeated monitoring of threatened populations.
FTIR-ATR comparison of lipid, ester, water and polysaccharide-associated motifs in reproductive adhesives.
Amplitude sweeps, frequency sweeps and creep-recovery tests on stigmatic soft materials.
Quasi-static adhesion tests, tensile deformation and pollinarium withdrawal measurements.
Polarised-light and optical documentation of cellular inclusions, gels and floral interfaces.
Species profiles, threat synthesis, locality evidence and future Red List workflows.
The habitat-replication work remains part of Orchidarc, but it now sits as research infrastructure: a tool for acclimatisation, experimental cultivation and conservation support.
The RAR Climate Replicator is an automated micro-greenhouse designed to reproduce the conditions orchids actually experience: humidity cycles, airflow, light transitions and controlled water delivery.
Its strongest conservation use is the transition from sterile culture to living habitat. Deflasked seedlings often fail because the shift from flask to greenhouse is too abrupt. A programmable chamber can create a controlled gradient between in-vitro propagation, acclimatisation and later ex-situ or field establishment.
