The mission of the U.S. Geological Survey is to provide reliable scientific information to: describe and understand the Earth; minimize loss of life and property from natural disasters; assist others in managing water, biological, and mineral resources; and enhance and protect quality of life. Northern Prairie Wildlife Research Center (NPWRC) is one of 18 science and technology centers in the Biological Resources Discipline, administratively positioned in the Central Region, and geographically located in the northern Great Plains. The web site provides information for wildlife managers, scientists, and the public on natural resource issues and biota of the North American Great Plains. ...

The atlas of Florida vascular plants is a joint effort by the Institute for Systematic Botany, the University of South Florida and the Florida Center for Community Design and Research to provide users with a comprehensive searchable database of vascular plants in the State of Florida. Records are based on collections in the four major Florida institutional herbaria having the largest holdings of Florida plants: University of Florida (FLAS), Florida State University (FSU), Fairchild Tropical Gardens (FTG), and University of South Florida (USF). ...

Distribution of all species: Distribution maps of more than 2600 plant species are available as GIF images. The plant names to select are in Latin, German, French and Italian. Additionally, Red List data and Landolt's indicator values are displayed. Distribution of rarest species: 132 distribution maps of very rare plants taken from the publication 'Merkblätter Artenschutz: Blütenpflanzen und Farne' (1999. Käsermann C. und Moser D.M.). Mapping areas: The distribution maps are based on an inventory conducted in 1967-79, for which information on species occurrences in 593 contiguous mapping areas was collected nationwide. Species richness: Information on regional diversity such as absolute number of species, simulated number of species, number of neophytes etc. The information comes in the form of commented maps.(German and italian only). ...

FloraWeb is the online offering of the Federal Agency for Nature Protection (BfN) concerning wild plant species, plant communities, and the natural vegetation of Germany. At present the species selection is restricted to ferns and flowering plants (phanerogams), the extension to mosses (bryophytes) is planned. The entries come from current, actualised databases and projects of the BfN and its co-operating partners (see below) and thus are available to the public in their current form. Under the menu point “Plant species” ("Pflanzenarten") ca. 3500 species profiles with up to 55 individual items of information about taxonomy, biology, ecology, habitat, distribution, and inventory situation, endangerment and protection, as well as photos, can be accessed that are generated at the current time by means of dynamic accessing the underlying databases. The species descriptions can be accessed by name, by alphabetical name lists, or a systematic family tree. Information about distributions in Germany is available through dynamically prepared maps and the interactive GIS application FloraMap. In the sub-menu point “Properties” ("Suche nach Eigenschaften") all individual information items in searches can be freely combined. Again, the resulting species lists can be transferred to the map module FloraMap where one then has the possibility of displaying the spatial distribution of these groups of species in Germany. Under the menu point “Associations” ("Gesellschaften"), the likewise collected information about plant communities and their regional endangerment in Germany is stored in the profiles. These profiles of the vegetation units are extended through a database of phytosociological records under the name “VegetWeb”, which is to be continuously expanded. Under the menu point “Vegetation map” the units of the potential natural vegetation of Germany are displayed in profiles, with text explanations and photos, that will be expanded through the map display dynamically linked to the profiles. The data-offering thus defined in the area “Data service” will be expanded in “InformationsNetz” with explanations of the botanical connections and further information about the data sources. ...

Der Botanische Informationsknoten Bayern ist ein Gemeinschaftsprojekt folgender Partner: Zentralstelle für die Floristische Kartierung Bayerns; Bayerisches Landesamt für Umwelt; Landesbund für Vogelschutz, Arbeitskreis Botanik. Diese Institutionen möchten hier die Daten, Informationen und Hilfsmittel zur Flora Bayerns bereitstellen, die ihnen selbst und anderen Quellen vorliegen. Ihr Ziel ist, auf diese Weise die verstreuten Ressourcen zu verknüpfen und damit die Kenntnisse um die bayerische Flora in Öffentlichkeit, Naturschutz und Wissenschaft zu fördern. ...

"Early Classics in Biogeography, Distribution, and Diversity Studies: To 1950" is a bibliography and full-text archive designed as a service to advanced students and researchers engaged in work in biogeography, biodiversity, history of science, and related studies. All items in the bibliography are primary sources and were published in 1950 or before. The subjects involved touch on fields ranging from ecology, conservation, systematics and physical geography, to evolutionary biology, cultural biogeography, paleobiology, and bioclimatology--but have in common a relevance to the study of geographical distribution and diversity. ...

A historical review of vegetation classification in Madagascar reveals that the classical map and "phytogeographic" territories of Perrier de la Bâthie and Humbert are largely a subjective reflection of climatological factors, and do not adequately reflect fundamental biogeographic patterns. Delimitation of phytochoria based on the distribution patterns of taxa provides an objective framework for comparing and mapping vegetation types using a simple physiognomic classification. The application of this approach in Madagascar would make it possible to test the validity of the classical divisions and circumscribe alternative ones, and to determine the current extent of natural and anthropogenic formations (principally secondary grasslands, often called "prairies", "pseudosteppes", etc., which cover about three quarters of the country). Before the arrival of man, the original woody vegetation types in the drier west (forest, woodland, bushland, etc.) were in a fragile equilibrium and could quickly have been converted to secondary grassland by fires; in the moister center more active human intervention (clearing) was likely required to alter the vegetation. Contrary to recent claims, native grasslands were not widespread immediately prior to the arrival of humans, but were probably restricted to small patches. Today, human impacts can be seen in all Malagasy vegetation types, even supposedly undisturbed "native" forest. ... [Information of the supplier]
ActKey was developed to enable ready-access to on-line interactive keys, including partly illustrated implementation of the punched card system for flowering plant family identification (by Hansen, B., and K. Rahn. 1969. Determination of angiosperm families by means of a punched-card system. Dansk Botanisk Arkiv 26:1-46 + 172 punched cards) and many other sources. ...
