Herbarium Berolinense, Berlin (B)

The herbarium of the Botanic Garden and Botanical Museum Berlin-Dahlem (herbarium acronym: B) is the largest in Germany and holds a collection of more than 3.5 million preserved specimens. All plant groups – flowering plants, ferns, mosses, liverworts, and algae, as well as fungi and lichens – are represented in the collections which are worldwide in scope. Associated with the general herbarium are special collections of dried fruits and seeds, wood samples, and specimens preserved in alcohol. The collections of the herbarium are growing constantly through field research conducted by staff, and through gifts, acquisitions, and exchanges of specimens from other herbaria

Vegetation data of four different short rotation coppice (SRC) life stages

<p>The dataset contains vegetation data collected in four different life stages of short rotation coppices (SRC): harvested, young (2 year old), mature (3 year old) and old (4 year old). In each SRC life stage, there were three sites established, in which a plot of 10 x 20 m was searched for vascular plant and fern species (Total = 12 sites). Each site was investigated once in May, June, July and August 2022. In may and June, plants were identified on species level according to the WFO Plant List and classified in terms of their relative ground cover according to a scale presented in Pfadenhauer et al. (1986): "Überlegungen zu einem Konzept geobotanischer Dauerbeobachtungsflächen für Bayern", complemented by an additional class containing single individuum findings. In the harvested SRCs, the plants were also identified in July and August because plant communities were expected to markedly change in these months as the poplars sprout out again and grew. In June, July and August, the number of flowering shoots were recorded for insect pollinated plant species at each site. </p>

Cheilanthane ratios in Mesoproterozoic to Early Paleozoic rocks

This data set contains values on the cheilanthane (tricyclic terpenoids) ratios of C22/C21 and C24/23 from Mesoproterozoic to Silurian rocks of global distribution. Lipid extractions were performed following standard protocols. The yield was contamination-controlled via exterior vs. interior comparison of individual peak concentrations. Values were obtained via integration of multiple-reaction-monitoring (MRM) measurements. In comparing our data of cheilanthane ratios to that reported for younger rocks and oils, we noticed consistently lower C24/C23 values in our samples, suggesting a bimodal character of cheilanthane distribution in time. We tentatively attribute this to the rise of a source of oxidatively decarboxylated cheilanthatriol derived from ferns. Fossil cheilanthanes likely represent a composite mixture of various biological sources, whose secular patterns may record more than the Paleozoic rise of terrestrial plants presented here.

Analyse der Verbreitung von Farn- und Blütenpflanzen in Naturräumen der Südpfalz unter Einbezug standörtlicher und landschaftsgenetischer Fragestellungen

Ziel des Projektes ist die Dokumentation des aktuellen Vorkommens indigener und synanthroper Pflanzensippen im Gebiet Verbreitungskarten in 1/64 Messtischblattraster). Durch Vergleich der aktuellen Verbreitung der Pflanzensippen mit historischen Quellen (Lit., Herb., hist. Karten, Luftbild) soll der Florenwandel dargestellt werden.

Untersuchungen zur Gefährdung von Farn- und Samenpflanzen als Grundlage für den Schutz der biologischen Vielfalt und für die Umsetzung der FFH-Richtlinie

Es wird die Funktion der Koordinierung der oben genannten Forschung für den Regierungsbezirk Leipzig übernommen. Es werden Daten über Verbreitung, Standortansprüche und Bestandsveränderungen von Farn- und Samenpflanzen erhoben und ausgewertet. Belegmaterial wird im Herbarium der Universität archiviert. Wir bieten anderen Institutionen, aber auch Einzelpersonen den Service an, taxonomisch schwierige Sippen zu determinieren bzw. Belege zu revidieren.
