“…The methods of collection, transportation, and storage by these insect and animal pollinating vectors play important roles in any subsequent interpretation of the importance of the types and abundance of collected pollen (Pendleton et al, 1996). Finally, once pollen is stored by insects or deposited on the ground as part of the pollen rain, its rate of deterioration will be affected by microbial activity, cycles of wetting and drying, pH, chemical oxidation, and mechanical breakdown of the cellulose and sporopollenin portions of the pollen wall (Bryant & Hall, 1993).…”
