Die in den beiden letzten Jahren abgeschlossenen Nationallizenzen haben Tatsachen geschaffen, die den Start zu einer Umstrukturierung der überregionalen Informationsversorgung erleichtern: - Versorgungslücken wurden geschlossen. - Die Durchdringung der Hochschulen und Forschungseinrichtungen mit elektronischer Fachinformation wurde vergleichbaren Ländern angeglichen. - Wissenschaftler, Studierende und wissenschaftlich interessierte Privatpersonen haben deutschlandweit kostenlosen Zugang zu einem fachlich breit gestreuten Angebot an retrospektiven Datenbanken, digitalen Textsammlungen und elektronischen Zeitschriften.
A bibliography (including an author index) of the literature on the land and freshwater molluscs of the Cape Verde Islands is presented, encompassing 81 entries, of which 61 are directly related to land and freshwater molluscs, while another 20 deal with marine Pulmonata and/or brackish and saltwater inhabiting Hydrobiidae. A historical synopsis of the exploration of the land and freshwater mollusc fauna of the Cape Verde archipelago is presented. An annotated check-list of the land-bound gastropods of the Cape Verde Islands is also included, differentiating between freshwater, land and marine species and completed by a list of taxa that have been erroneously mentioned for the archipelago due to misidentification or confusion about the location of origin.
The Revue des Sciences naturelles de l’Ouest was edited in the years 1891-97. Although poorly known, it contains valuable papers on the natural sciences in Western France, particularly in Vendée. After a short presentation, we give here the content tables of this periodical together with a list of public libraries where it can be found.
A taxonomic overview for the fritillary genus Speyeria Scudder (= Argynnis Fabricius) and its placement within the Heliconiinae (Nymphalidae) is presented. Taxonomic accounts, type images, and relevant literature for the 25 subspecies within the Speyeria atlantis (Edwards) and Speyeria hesperis (Edwards) complexes and the 16 nominate Speyeria species are included. Errors in nomenclature are identified, taxonomic, life history, and distributional information are updated, and type locality information is discussed. Images of primary type specimens for all 16 Speyeria species and the 25 subspecies in the atlantis - hesperis complexes appear together in color here for the first time. One new combination of a species-subspecies is created: Speyeria hesperis hanseni Emmel, Emmel, and Matoon, 1998, new combination, which was previously Speyeria atlantis hanseni Emmel, Emmel, and Matoon.
