“…Molecular studies have shown that this liverwort is a complex of six cryptic species (A, C, F, J, L and S). [19,42] Conocephalum conicum growing in Japan (J-type) produces sabinene (28) as the major volatile component. In addition other monoterpenoids, limonene (29), bornyl acetate (30), camphene (31) and β-pinene (32), and sesquiterpenoids form the germacrane type, for example germacrene D (33) and 1(10),4-germacradien-11-ol (34) were detected in the ether extracts obtained from this species.…”

“…[44] This brasilane-type sesquiterpene alcohol is suggested to be the chemical marker of cryptic species L within the C. conicum complex. [19] The liverwort Reboulia hemisphaerica has at least three chemotypes: atistolane (I), cyclomyltaylane-bisbibenzyl (II), and gymnomitrane-cuparane (III).

A number of liverwort species are known to emit volatile terpenoids and simple aromatic compounds when crushed. The characteristic odour of these spore-forming plants is associated with oil body constituents. Secondary metabolites, which constitute the oil bodies, are also of value for taxonomic investigations. Liverworts have yielded a rich array of secondary metabolites. Many of these compounds are characterized by unique structures, and some of them have not been found in any other plants, fungi, or marine organisms. Gas chromatographic profiling of the volatile extracts obtained from the liverworts has been applied with success in differentiating liverworts species, and also used to resolve the taxonomic problems at genus and family level. Due to the fact that liverworts are morphologically very small and it is difficult to collect a sufficient amount of plant material, there are few research data on the composition of the essential oils obtained from these plants. Nevertheless, the available data indicate that, as in the case of aromatic plants, the components present in essential oils obtained from the liverworts can be used in chemosystematic studies of this plant group. The aim of this paper is to show whether: (i) there are differences in the essential oils composition between different liverwort species; (ii) it is possible to find chemical markers characteristic for the analysed liverwort species; and (iii) the data derived from an analysis of the essential oils are in accordance with the data received from volatile extracts.

“…Because differences in the profiles of volatiles produced by different phenotypes reflect changes on the genetic level, chemosystematics based on volatile organic compounds could be useful to taxonomists and ecologists for better identification and classification of fungi in this group. Studies have shown that cryptic species within a species complex differ significantly in their volatile profiles (Ludwiczuk et al 2013; Wawrzyniak et al 2014), and so by using such methods it should be possible to differentiate among the cryptic species previously described in the G. clavigera complex (Alamouti et al 2011). …”

Volatile Organic Compounds Emitted by Fungal Associates of Conifer Bark Beetles and their Potential in Bark Beetle Control

Conifer bark beetles attack and kill mature spruce and pine trees, especially during hot and dry conditions. These beetles are closely associated with ophiostomatoid fungi of the Ascomycetes, including the genera Ophiostoma, Grosmannia, and Endoconidiophora, which enhance beetle success by improving nutrition and modifying their substrate, but also have negative impacts on beetles by attracting predators and parasites. A survey of the literature and our own data revealed that ophiostomatoid fungi emit a variety of volatile organic compounds under laboratory conditions including fusel alcohols, terpenoids, aromatic compounds, and aliphatic alcohols. Many of these compounds already have been shown to elicit behavioral responses from bark beetles, functioning as attractants or repellents, often as synergists to compounds currently used in bark beetle control. Thus, these compounds could serve as valuable new agents for bark beetle management. However, bark beetle associations with fungi are very complex. Beetle behavior varies with the species of fungus, the stage of the beetle life cycle, the host tree quality, and probably with changes in the emission rate of fungal volatiles. Additional research on bark beetles and their symbiotic associates is necessary before the basic significance of ophiostomatoid fungal volatiles can be understood and their applied potential realized.Electronic supplementary materialThe online version of this article (doi:10.1007/s10886-016-0768-x) contains supplementary material, which is available to authorized users.

Bryophytes occur in almost all land ecosystems and contribute to global biogeochemical cycles, ecosystem functioning, and influence vegetation dynamics. As growth and biochemistry of bryophytes are strongly dependent on the season, we analyzed metabolic variation across seasons with regard to ecological characteristics and phylogeny. Using bioinformatics methods, we present an integrative and reproducible approach to connect ecology with biochemistry. Nine different bryophyte species were collected in three composite samples in four seasons. Untargeted liquid chromatography coupled with mass spectrometry (LC/MS) was performed to obtain metabolite profiles. Redundancy analysis, Pearson's correlation, Shannon diversity, and hierarchical clustering were used to determine relationships among species, seasons, ecological characteristics, and hierarchical clustering. Metabolite profiles of Marchantia polymorpha and Fissidens taxifolius which are species with ruderal life strategy (R‐selected) showed low seasonal variability, while the profiles of the pleurocarpous mosses and Grimmia pulvinata which have characteristics of a competitive strategy (C‐selected) were more variable. Polytrichum strictum and Plagiomnium undulatum had intermediary life strategies. Our study revealed strong species‐specific differences in metabolite profiles between the seasons. Life strategies, growth forms, and indicator values for light and soil were among the most important ecological predictors. We demonstrate that untargeted Eco‐Metabolomics provide useful biochemical insight that improves our understanding of fundamental ecological strategies.
