Die Zikadenfauna des Maggelhansluches: Tyrphobionte und tyrphophile Indikatoren für die naturschutzfachliche Bewertung eines brandenburgischen Kesselmoores: (Hemiptera, Auchenorrhyncha)
Full text linkThe Auchenorrhyncha fauna of the Maggelhansluch – tyrphobiotic and tyrphophilous insects as indicators for habitat evaluation of a hollow peat bog in Brandenburg (Germany). – In 2001 and 2002 the Auchenorrhyncha fauna of an intermediate bog called ‚Maggelhansluch‘ (Brandenburg, Germany) was surveyed as part of a broader project monitoring the tyrphophilic and tyrphobiotic species of several invertebrate groups. Although a motorway cuts through the site since the 1930‘s, still a total of 56 Auchenorrhyncha species was found, including 9 peatland specialists. This considerable high number of specialists indicates a particular importance of the surveyed bog for conservation. Noteworthy, threatened, or stenotopic species included the rare and little known delphacid planthoppers Kelisia confusa and Criomorphus moestus
The Auchenorrhyncha communities of chalk grassland in southern England
No full textDue to their confinement to specific host plants or restricted habitat types, Auchenorrhyncha are suitable biological indicators to measure the quality of chalk grassland under different management practices for nature conservation. They can especially be used as a tool to assess the success of restoring chalk grassland on ex-arable land. One objective of this study was to identify the factors which most effectively conserve and enhance biological diversity of existing chalk grasslands or allow the creation of new areas of such species-rich grassland on ex-arable land. A second objective was to link Auchenorrhyncha communities to the different grassland communities occurring on chalk according to the NVC (National Vegetation Classification). Altogether 100 chalk grassland and arable reversion sites were sampled between 1998 and 2002. Some of the arable reversion sites had been under certain grazing or mowing regimes for up to ten years by 2002. Vegetation structure and composition were recorded, and Auchenorrhyncha were sampled three times during the summer of each year using a "vortis" suction sampler. Altogether 110 leafhopper species were recorded during the study. Two of the species, Kelisia occirrega and Psammotettix helvolus, although widespread within the area studied, had not previously been recognized as part of the British fauna. By displaying insect frequency and dominance as it is commonly done for vegetation communities, it was possible to classify preferential and differential species of distinct Auchenorrhyncha communities. The linking of the entomological data with vegetation communities defined by the NVC showed that different vegetation communities were reflected by distinct Auchenorrhyncha communities. Significant differences were observed down to the level of sub-communities. The data revealed a strong positive relationship between the diversity of leafhoppers species and the vegetation height. There was also a positive correlation between the species richness of Auchenorrhyncha and the diversity of plant species. In that context it is remarkable that there was no correlation between vegetation height and botanical diversity. There is a substantial decrease in Auchenorrhyncha species richness from unimproved grassland to improved grassland and arable reversion. The decline of typical chalk grassland and general dry grassland species is especially notable. Consequently, the number of stenotopic Auchenorrhyncha species which are confined to only a few habitat types, are drastically reduced with the improvement of chalk grassland. Improved grassland and arable reversion fields are almost exclusively inhabited by common habitat generalists. The decrease in typical chalk grassland plants due to improvement is mirrored in the decline of Auchenorrhyncha species, which rely monophagously or oligophagously on specific host plants. But even where suitable host plants re-colonize arable reversion sites quickly, there is a considerable delay before leafhoppers follow. That becomes especially obvious with polyphagous leafhoppers like Turrutus socialis or Mocydia crocea, which occur on improved grassland or arable reversion sites only in low frequency and abundance, despite wide appearance or even increased dominance of their host plants. These species can be considered as the most suitable indicators to measure success or failure of long term grassland restoration. A time period of ten years is not sufficient to restore species-rich invertebrate communities on grassland, even if the flora indicates an early success

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
