dc.description.abstract | Rationale Plant lipid biomarkers, such as plant waxes and terpenoids, and the stable isotopic composition of bulk leaves are widely used in both modern and paleoclimate studies for tracking vegetation and climate. However, the effects of different drying methods on the preservation of plant lipid biomarkers and the stable isotopic compositions of leaves are less explored. Here, we investigated various drying methods for the measurement of plant lipid concentrations and bulk leaf isotopic compositions. Methods Leaves from four tree species (Acer rubrum,Pinus sylvestris,Platanus occidentalis, andTaxodium distichum) were collected and dried using air, an oven, a freeze-dryer, and a microwave. We compared concentrations of leaf waxes and terpenoids and carbon (delta C-13) and nitrogen (delta N-15) isotopic compositions of leaves by different drying methods. Results The air, oven, freeze-dryer, and microwave drying methods did not affect lipid concentrations significantly, and only a few homologues differed (38.1% or 41.8 mu g/g on average) possibly due to biological variations or enhanced extraction efficiencies. The delta C-13 values were not affected by drying methods, whereas the delta N-15 values in oven-dried leaves in some species were higher by 0.2-0.7 parts per thousand than those obtained by other methods. Though small, we attribute these patterns to loss of leaf compounds with lower isotope ratios during oven-drying. Conclusions Based on our results, each drying technique yielded equivalent results for all plant wax and terpenoid concentrations and bulk leaf delta C-13 values; however, oven-drying modified the delta N-15 values. | - |
