2021 Frontiers in Microbiology  
Understanding microbial community dynamics in the alpine cryosphere is an important step toward assessing climate change impacts on these fragile ecosystems and meltwater-fed environments downstream. In this study, we analyzed microbial community composition, variation in community alpha and beta diversity, and the number of prokaryotic cells and virus-like particles (VLP) in seasonal snowpack from two consecutive years at three high altitude mountain summits along a longitudinal transect

Numbers of prokaryotic cells and VLP both ranged around 104 and 105 per mL of snow meltwater on average, with variation generally within one order of magnitude between sites and years. VLP-to-prokaryotic cell ratios spanned two orders of magnitude, with median values close to 1, and little variation between sites and years in the majority of cases. Estimates of microbial community alpha diversity inferred from Hill numbers revealed low contributions of common and abundant microbial taxa to the total taxon richness, and thus low community evenness. Similar to prokaryotic cell and VLP numbers, differences in alpha diversity between years and sites were generally relatively modest. In contrast, community composition displayed strong variation between sites and especially between years. Analyses of taxonomic and phylogenetic community composition showed that differences between sites within years were mainly characterized by changes in abundances of microbial taxa from similar phylogenetic clades, whereas shifts between years were due to significant phylogenetic turnover. Our findings on the spatiotemporal dynamics and magnitude of variation of microbial abundances, community diversity, and composition in surface snow may help define baseline levels to assess future impacts of climate change on the alpine cryosphere.

The Reactome Knowledgebase (www.reactome.org) provides molecular details of signal transduction, transport, DNA replication, metabolism and other cellular processes as an ordered network of molecular transformations--an extended version of a classic metabolic map, in a single consistent data model. Reactome functions both as an archive of biological processes and as a tool for discovering unexpected functional relationships in data such as gene expression pattern surveys or somatic mutation

A new pathway diagram viewer provides a faster, clearer interface and smooth zooming from the entire reaction network to the details of individual reactions. Tool performance for analysis of user datasets has been substantially improved, now generating detailed results for genome-wide expression datasets within seconds. The analysis module can now be accessed through a RESTFul interface, facilitating its inclusion in third party applications. A new overview module allows the visualization of analysis results on a genome-wide Reactome pathway hierarchy using a single screen page. The search interface now provides auto-completion as well as a faceted search to narrow result lists efficiently.

The Lipid Status in Patients with Ulcerative Colitis: Sphingolipids are Disease-Dependent Regulated

The factors that contribute to the development of ulcerative colitis (UC), are still not fully identified. Disruption of the colon barrier is one of the first events leading to invasion of bacteria and activation of the immune system. The colon barrier is strongly influenced by sphingolipids. Sphingolipids impact cell–cell contacts and function as second messengers. We collected blood and colon tissue samples from UC patients and healthy controls and investigated the sphingolipids and other

In inflamed colon tissue, the de novo-synthesis of sphingolipids is reduced, whereas lactosylceramides are increased. Reduction of dihydroceramides was due to posttranslational inhibition rather than altered serine palmitoyl transferase or ceramide synthase expression in inflamed colon tissue. Furthermore, in human plasma from UC-patients, several sphinglipids change significantly in comparison to healthy controls. Beside sphingolipids free fatty acids, lysophosphatidylcholines and triglycerides changed significantly in the blood of colitis patients dependent on the disease severity. Our data indicate that detraction of the sphingolipid de novo synthesis in colon tissue might be an important trigger for UC. Several lipids changed significantly in the blood, which might be used as biomarkers for disease control; however, diet-related variabilities need to be considered.

Das Klima und die Witterung sind prägende Faktoren für den Pflanzenschutz. Bereits vor 100 Jahren haben sich Wissenschaftler im Nachrichtenblatt für den Deutschen Pflanzenschutzdienst dieser Thematik gewidmet. Die Auswirkungen des Klimawandels sind ambivalent und es wird insgesamt zu einer Veränderung des Schaderregerspektrums kommen. Tendenziell werden Schäden durch Insekten, Krankheitserreger und wärmetolerante Unkräu­ter begünstigt. Das Risiko der Etablierung invasiver Arten nimmt zu. Ebenso

Beim chemischen Pflanzenschutz wird sich das Wirkstoffspektrum verschieben und die Anforderungen an Applikationstechnik und -termin steigen. Starkregen kann das Risiko des Austrags von Pflanzenschutzmitteln in die Umwelt steigern. Auch in Mitteleuropa kann es verstärkt zu Befall mit Vorratsschädlingen bereits im Feld kommen und die Qualität und Lagerstabilität der Ernteprodukte abnehmen. Ins­gesamt wird die Bedeutung präventiver Pflanzenschutzmaßnahmen zunehmen. Die Folgen des Klimawandels erhöhen die betriebs- und volkswirtschaftlichen Risiken und stellen alle Akteursebenen vor erhebliche Heraus­forderungen.
