  Molecular diversity surveys have demonstrated that aquatic fungi are highly diverse, and that they play fundamental ecological roles in aquatic systems. Unfortunately, comparative studies of aquatic fungal communities are few and far between, due to the scarcity of adequate datasets. We combined all publicly available fungal 18S ribosomal RNA (rRNA) gene sequences with new sequence data from a marine fungi culture collection. We further enriched this dataset by adding validated contextual data. Specifically, we included data on the habitat type of the samples assigning fungal taxa to ten different habitat categories. This dataset has been created with the intention to serve as a valuable reference dataset for aquatic fungi including a phylogenetic reference tree. The combined data enabled us to infer fungal community patterns in aquatic systems. Pairwise habitat comparisons showed significant phylogenetic differences, indicating that habitat strongly affects fungal community structure. Fungal taxonomic composition differed considerably even on phylum and class level. Freshwater fungal assemblage was most different from all other habitat types and was dominated by basal fungal lineages. For most communities, phylogenetic signals indicated clustering of sequences suggesting that environmental factors were the main drivers of fungal community structure, rather than species competition. Thus, the diversification process of aquatic fungi must be highly clade specific in some cases.The combined data enabled us to infer fungal community patterns in aquatic systems.

• Das Ehegattensplitting aus Sicht der Steuerwissenschaften

  Chirvi, M. ., & Maiterth, R. . (2015). Das Ehegattensplitting aus Sicht der Steuerwissenschaften. Steuer Und Wirtschaft, 92(1). http://doi.org/10.9785/stuw-2015-920103

  Abstract

  anzeigen ▸

  Ob das Ehegattensplitting einer Individualbesteuerung tatsächlich "unterlegen" ist, erscheint zweifelhaft. Zum einen sind die geschätzten positiven Arbeitsangebotseffekte aufgrund des geänderten weiblichen Erwerbsverhaltens inzwischen relativ gering und im Verhältnis zur Gesamtzahl der Beschäftigten in Deutschland marginal. Beim Realsplitting, das aus verfassungsrechtlichen Gründen - anders als die Individualbesteuerung - eine realistische Option darstellt, sind die Arbeitsangebotseffekte vernachlässigbar. Zum anderen sprechen steuererhebungstechnische Aspekte, die in der Besteuerungsrealität außerordentlich bedeutsam sind aber in der Diskussion kaum genannt werden, zweifelsfrei für das Ehegattensplitting.

• Low carbon supply chain configuration for a new product – a goal programming approach

  Brandenburg, M. . (2015). Low carbon supply chain configuration for a new product – a goal programming approach. International Journal of Production Research, 53, 6588–6610. http://doi.org/10.1080/00207543.2015.1005761

  Green supply chain management and product innovation both have become sources of competitive advantage for companies from different industries. However, research on the configuration of green supply chains for new products represents a comparably new trend. In this paper, a goal programming approach is suggested to optimise the supply chain (SC) configuration for a new consumer product under consideration of economic and environmental criteria. The approach is illustrated by the case example of a fast moving consumer goods manufacturer. In this context, trade-offs between the ecologic factor of carbon emission, on the one hand, and financial value creation and customer service level on the other hand, are assessed in the deterministic analyses. The influence of long-term demand uncertainties is modelled in a scenario approach. It is observed that decentralised SC configurations enable carbon emission reduction without deteriorating the economic SC performance. Furthermore, it is detected that a focused economic optimisation strongly amplifies negative environmental impacts of demand uncertainties.

• Lindgomycin, an Unusual Antibiotic Polyketide from a Marine Fungus of the Lindgomycetaceae

  Wu, B. ., Wiese, J. ., Labes, A. ., Kramer, A. ., Schmaljohann, R. ., & Imhoff, J. F. (2015). Lindgomycin, an Unusual Antibiotic Polyketide from a Marine Fungus of the Lindgomycetaceae. Marine Drugs, 13, 4617–4632. Abgerufen von http://oceanrep.geomar.de/29518/

  Abstract

  anzeigen ▸

  An unusual polyketide with a new carbon skeleton, lindgomycin (1), and the recently described ascosetin (2) were extracted from mycelia and culture broth of different Lindgomycetaceae strains, which were isolated from a sponge of the Kiel Fjord in the Baltic Sea (Germany) and from the Antarctic. Their structures were established by spectroscopic means. In the new polyketide, two distinct domains, a bicyclic hydrocarbon and a tetramic acid, are connected by a bridging carbonyl. The tetramic acid substructure of compound 1 was proved to possess a unique 5-benzylpyrrolidine-2,4-dione unit. The combination of 5-benzylpyrrolidine-2,4-dione of compound 1 in its tetramic acid half and 3-methylbut-3-enoic acid pendant in its decalin half allow the assignment of a new carbon skeleton. The new compound 1 and ascosetin showed antibiotic activities with IC50 value of 5.1 ($\pm$0.2) ?M and 3.2 ($\pm$0.4) \ensuremath\muM, respectively, against methicillin-resistant Staphylococcus aureus.
