Protocols

Laboratory protocol for preparing yeast-inoculated synthetic nectar with species-specific concentrations and incubation conditions. Synthetic nectar designed to match natural nectar composition.

Standard protocol for preserving unidentifiable specimens in ethanol, followed by pinning and taxonomic identification in laboratory conditions.

Laboratory feeding trials exposing individual bumblebee workers to alkaloid-enriched sucrose solutions followed by behavioral activity scoring to assess direct consumptive effects of nectar alkaloids.

Standardized biochemical assays for quantifying protein, lipid, and carbohydrate content in pollen samples. Uses Bradford assay for proteins and sulfo-phospho-vanillin and anthrone-sulfuric acid assay...
