The Pennsylvania State University The Graduate School Department of Geosciences STABLE ISOTOPE AND LIPID SIGNATURES OF PLANTS ACROSS A CLIMATE GRADIENT: IMPLICATIONS FOR BIOMARKER-BASED PALEOCLIMATE RECONSTRUCTIONS A Thesis in Geosciences by Christine E. Doman 2015 Christine E. Doman Submitted in Partial Fulfillment of the Requirements for the Degree of Master of Science August 2015 ii The thesis of Christine E. Doman was reviewed and approved* by the following: Katherine H. Freeman Professor of Geoscience Thesis Advisor Mark Patzkowsky Professor of Geosciences Matthew Fantle Associate Professor of Geosciences Demian Saffer Professor of Geosciences Interim Associate Head of Graduate Programs *Signatures are on file in the Graduate School iii ABSTRACT Plant wax n-alkanes are long, saturated hydrocarbons that form part of the protective, waxy cuticle on leaves. These lipids are pervasive and persistent in soils and sediments and are ideal biomarkers of ancient terrestrial organic matter. In ecosystems dominated by C3 plants, fractionation of carbon and hydrogen isotopes during production of whole leaves and hydrocarbon lipids are well documented, but the sensitivity of isotopic fractionation between leaves and lipids to climate has not been fully investigated. Further, there are few studies of stable isotopes in C4 plant lipids. In both cases, it is unclear if carbon and hydrogen isotopic fractionations during lipid production are sensitive to environmental conditions, such as moisture, or if they reflect inherited characteristics tied to taxonomic or phylogenetic affiliation. This study used a natural climate gradient on the Kohala peninsula of Hawaii to investigate relationships 13 2 between climate and the δ C and δ H values of n-alkanes in three taxa of C3 and two taxa of C4 plants. -

Morphology and Accumulation of Epicuticular Wax on Needles of Douglas-Fir Pseudotsuga( Menziesii Var
Constance A. Harrington1 and William C. Carlson, USDA Forest Service, Pacific Northwest Research Station, 3625 93rd Ave. SW, Olympia, Washington 98512 Morphology and Accumulation of Epicuticular Wax on Needles of Douglas-fir (Pseudotsuga menziesii var. menziesii) Abstract Past studies have documented differences in epicuticular wax among several tree species but little attention has been paid to changes in accumulation of foliar wax that can occur during the year. We sampled current-year needles from the termi- nal shoots of Douglas-fir (Pseudotsuga menziesii var. menziesii) in late June/early July, late August and early November. Needles were sampled from two sites that differed in their climate and shoot phenology. Adaxial (upper), abaxial (lower) and cross-sectional surfaces were examined on scanning electron micrographs. Wax thickness increased significantly (P < 0.01) during the year (from 2.9 ± 0.26 µm in late June/early July to 4.4 ± 0.13 µm in early November). Mean wax thick- ness was slightly thicker on adaxial (4.0 ± 0.16 µm) than on abaxial (3.5 ± 0.22 µm) surfaces (P = 0.03). There were no significant differences in wax thickness between needles sampled at the base of the terminal shoot or near the tip of the shoot. Tubular or rod-shaped epicuticular wax crystals were sparsely developed on adaxial surfaces, completely covered abaxial surfaces (including filling all stomatal cavities), and had the same general structure and appearance across sites and sampling dates. Some erosion of epicuticular wax crystals on adaxial surfaces and presence of amorphous wax on abaxial surfaces was observed late in the year when epicuticular wax thickness was the thickest. -

Its genotype was identified by a botanist. The wax was extracted using solvent extraction. The fatty acid profiles and physicochemical properties of the wax namely melting point, congealing point, crystal structures and polymorphism, hardness, color, and solubility were examined and compared to those of beeswax, carnauba wax and paraffin wax. The results showed that the genotype of Kluai Namwa was Musa acuminata X M. balbisiana (ABB group) cv. Pisang Awak. The highest amount of wax extracted was 274 g/cm2 surface area. The fatty acid composition and the physicochemical properties of the wax were similar to those of carnauba wax. It could be suggested that the banana wax could be used as a replacement for carnauba wax in various utilizing areas. Keywords: epicuticular wax, banana wax, Kluai Namwa, Musa spp. carnauba wax 1. Introduction air pollution. However, it is interesting that, the outermost part of banana leaf is covered with lipid substance, which is Banana (Musa spp.) is one of the most widely so-called the epicuticular wax. -

Newsletter No. 4 Autumn 2005
The Southern African Bulb Group Newsletter No. 4 Autumn 2005 The Southern African Bulb Group was initiated by a group of enthusiasts on April 4th 2004. The objective of the group is to further the understanding of the cultivation of Southern African bulbs, where `bulbs' is used in the broad sense to encompass bulb-, corm- and tuber- possessing Southern African plants, including `dicots' such as Oxalis. In the first instance the group will be run on an informal basis, with an initial subscription of £5 invited from participants. Committee: Robin Attrill (Membership secretary and Newsletter editor), Margaret Corina (Treasurer), Stefan Rau and Terry Smale Editorial This issue of the newsletter contains a report of the meeting of the group held at Rupert Bowlby's Nursery on April 9th 2005, an article on Crinum moorei by David Corina, information on recent literature of interest to growers of Southern African bulbs, and an updated list of suppliers of seed and bulbs/corms of Southern African geophytes. In addition a balance sheet covering the first year of operation of the group is attached. With respect to the supplier list, please let me know if you are aware of other sources which should be included. As I have previously stated the group welcomes articles, and suggestions, for inclusion in future newsletters. Contributions (hand/typewritten and electronic are acceptable!) are urgently required and should be sent to the newsletter editor at 17 Waterhouse Moor, Harlow, Essex, CM18 6BA (Email [email protected] ) Publication of the next issue is scheduled for December 2005. Report on visit to Rupert Bowlby - Saturday 9 th April 2005 by David Corina About 20 members attended the event, and the Group would like to thank Rupert for his hospitality at the event and for opening his collection to the public gaze.
