Die Datenbank biologisch-ökologischer Merkmale der Flora Deutschlands (BiolFlor) berücksichtigt 3659 Arten von Farn- und Blütenpflanzen einschließlich der in Deutschland etablierten Neophyten sowie der häufigsten unbeständigen Sippen. Sie ist die erste biologisch-ökologische Datenbank für die gesamte Gefäßpflanzenflora Deutschlands mit Angaben zu über 60 Merkmalen aus den Bereichen: Floristischer Status / Chromosomenzahlen, Ploidiegrade, DNA-Gehalte / Phylogenie / Morphologie der vegetativen Organe / Blühphänologie / Blüten- und Reproduktionsbiologie / Merkmale der Samen, Früchte, Ausbreitungs- und Keimungseinheiten / Ökologische Strategietypen / Nutzungswertzahlen der Pflanzenarten des Grünlandes / Geographische Areale / Indikation des anthropogenen Einflusses auf die Vegetation / Biotopbindung / Pflanzensoziologische Bindung. Durch die Aufnahme der Synonyme der wissenschaftlichen Pflanzennamen aus der "Standardliste" von Wisskirchen und Haeupler ist unabhängig von der zur Recherche verwendeten Nomenklatur ein einfacher Zugriff auf die Daten möglich. Inhaltliche Grundlage von BiolFlor sind bereits vorhandene Datenbanken, eine umfangreiche Literaturauswertung (über 1800 Literaturquellen) sowie neue Datenerhebungen und Zusammenfassungen von Expertenwissen. Die Such- und Recherchefunktionen stehen nur registrierten Benutzern zur Verfügung, die die Buch- und CD-Version von BiolFlor erworben haben. ... [Information des Anbieters]
Die in 23 Teilbänden erscheinende, 1906 von Gustav Hegi begründete Illustrierte Flora von Mitteleuropa gilt als die umfassendste Informationsquelle über die Pflanzenwelt dieses Gebietes. Es umschließt außer den deutschsprachigen Ländern auch das ehemalige Ostpreußen, das westliche Polen, Böhmen, Mähren, Luxemburg, Elsass und Lothringen sowie die Schweiz, die italienischen Südalpen und Slowenien. Bewährtes Prinzip des Hegi ist es, eine vielseitige und grundlegende Darstellung der mitteleuropäischen Flora zu liefern, die hohen wissenschaftlichen Ansprüchen genügt, aber gleichzeitig auch über den Kreis der Berufsbotaniker hinaus eine breite Resonanz und weite Verbreitung findet und gefunden hat. ...

Since 2001 the German Working Group on Vegetation Databases is dedicated to the development of phytosociological databases. In the face of rampant biodiversity loss, the care for native species and the restoration of communities and ecosystem functions has become an important tool for nature conservation. Interfering with ecological complexity, restoration has to be informed by profound knowledge of species and their interactions in communities. To anticipate actionism, its success has to be carefully measured. Vegetation databases must play a crucial role in the planning, monitoring and readjustment of restoration measures. As comprehensive archives of species co-occurrence vegetation databases allow to define target species and forecast interactions with their competitors and facilitators. For given target species, they allow to identify habitats and communities most suited for re-establishment. Monitoring data stored in databases are readily accessible to statistical analysis of effects and trajectories. The German working group on vegetation databases has therefore chosen ecological restoration as the focal topic of its 13th workshop to be held at the Federal Institute of Hydrology (BFG) in Koblenz from 24 - 26 February 2014. ...

Vegetation databases have proven an irreplaceable medium to store and maintain the vast volume of data produced by vegetation scientists worldwide. They do not only protect data and the laborious work invested to produce them from getting lost, but also enable scientists to analyse large datasets in order to answer current research questions. A major task of present research is to find underlying ecological, temporal and spatial processes that shape plant communities. In this context, databases can serve as important tools supplementing experimental approaches. Inference of processes requires e.g. linkages to environmental data at adequate temporal and spatial scales and plant functional data, but also advanced statistical methods like path analysis techniques. The next meeting of the German Working Group on Vegetation Databases is dedicated to the role databases are playing in detecting ecological processes from various vegetation-related data. We encourage presentations (talks and posters) focussing on questions and methods with special emphasis on the analysis of vegetation data with respect to underlying ecological processes and cause and effect relationships. Besides, more general contributions on other technical or scientific advances in vegetation databanking are welcome. The workshop will be hosted by the Landscape Ecology Group of the University of Oldenburg from 4th to 6th of March 2015. We will start the workshop by giving an introduction to path analysis and structural equation modelling (Wednesday, 4th of March). These statistical analyses are well suited to identify causal relationships between parameters, test ecological hypotheses for their significance and are able to deal with large datasets. The following two days will we dedicated to talks and posters presenting ecological research questions inferred from vegetation databases. ... [Information of the supplier]
Palearctic dry grasslands have a long tradition of community analysis and description, leading to a detailed picture of these habitats, especially in Central Europe. In contrast, research on the biology of species and populations, such as pollination biology, dispersal ecology, demography or population genetics, is expanding rapidly. The connection between the two scientific disciplines is often weak although, actually, populations are part of communities and communities consist out of populations. We will therefore focus on this connection between population biology and community ecology for all dry grassland biota (invertebrates, vertebrates, non-vascular plants, vascular plants, fungi and lichens) as the overall topic of the next EDGM. ...
