“…diketones [8] [9], and it is under a strong genetic control [10] [11], because of its very important role. Among the compounds constituting the epicuticular waxes, n-alkanes have been studied extensively as chemotaxonomic markers in different plant families [12 -33], because of their easy and fast extraction and identification, but also because of their chemical stability.…”

“…Maffei et al [43] showed that leaf-wax n-alkanes extracted from Pinales needles are good chemotaxonomic markers, able to allow separation at the familial and subfamilial level. Dodd and AfzalRafii [11] analyzed waxes of plant species of the Cupressaceae family and proposed that the hydrocarbon composition displayed a strong genetic influence of adaptation to environmental conditions.…”

The composition of the cuticular n-alkanes isolated from the leaves of nine populations of Juniperus deltoides R.P.Adams from continental and coastal areas of the Balkan Peninsula was characterized by GC-FID and GC/MS analyses. In the leaf waxes, 14 n-alkane homologues with chain-lengths ranging from C22 to C35 were identified. n-Tritriacontane (C33 ) was dominant in the waxes of all populations, but variations between the populations in the contents of all n-alkanes were observed. Several statistical methods (ANOVA, principal component, discriminant, and cluster analyses) were used to investigate the diversity and variability of the cuticular-leaf-n-alkane patterns of the nine J. deltoides populations. This is the first report on the n-alkane composition for this species. The multivariate statistical analyses evidenced a high correlation of the leaf-n-alkane pattern with the geographical distribution of the investigated samples, differentiating the coastal from the continental populations of this taxon.

This is the first report of population variability of the contents of n-alkanes and nonacosan-10-ol in the needle epicuticular waxes of Serbian spruce (Picea omorika). The hexane extracts of needle samples originated from three natural populations in Serbia (Vranjak, Zmajevački potok, and Mileševka Canyon) were investigated by GC and GC/MS analyses. The amount of nonacosan-10-ol varied individually from 50.05 to 74.42% (65.74% in average), but the differences between the three investigated populations were not statistically confirmed. The results exhibited variability of the composition of n-alkanes in the epicuticular waxes with their size ranging from C(18) to C(35). The most abundant n-alkanes were C(29), C(31), and C(27) (35.22, 13.77, and 12.28% in average, resp.). The carbon preference index of all the n-alkanes (CPI(total)) of the P. omorika populations (average of populations I-III) ranged from 3.3 to 11.5 (mean of 5.9), while the average chain length (ACL) ranged from 26.6 to 29.2. The principal component and cluster analyses of the contents of nine n-alkanes showed the greatest difference for the population growing in the Mileševka Canyon. The obtained results were compared with previous literature data given for other Picea species, and this comparison was briefly discussed.

“…1) (Zheng et al, 2007). On top of different sources, odd-numbered long-chain n-alkanes are generated as moisture-regulating epicuticular leaf waxes (Tulloch, 1976), and longer-chain length n-alkanes tend to be synthesized under water stress responding to elevated temperatures and aridity, in order to provide a more efficient wax coating (Dodd and Rafii, 2000;Shepherd and Griffiths, 2006).…”

Lipid biomarkers and pertinent indices from aquatic environment record paleoclimate and paleoenvironment changes

a b s t r a c tLipid biomarkers and their pertinent indices have been used as the most effective proxies for paleoclimate and paleoenvironment conditions. This paper conducts a systematic review on a variety of lipid biomarkers in aquatic sediments and water column that are used as proxies tracing paleoclimate and paleoenvironment information. The sources of those lipid biomarkers are autochthonous and/or allochthonous. General mechanisms of lipid biomarkers used as paleoclimate and paleoenvironment archives include characteristics of carbon chain distribution, temperature adaptation and combined temperature and humidity adaptation. Different lipid indices underpinned by the mechanisms are surrogates for the past precipitation, temperature and humidity as well as plant succession. We propose that the combined use of lipid indices and other biomarkers can expand the outlook of individual index, and provide a better understanding of paleoclimate and paleoenvironment reconstruction.
