Discovery of a new inland population of Amara strenua Zimmerman, 1832 at Heverlee, central Belgium (Coleoptera: Carabidae)
No full textA new inland population of the rare ground beetle Amara strenua Zimmerman, 1832 is reported for Belgium. This species was encountered during a survey using pitfall traps at Abdij van Park near Heverlee. This observation marks the first record in Flemish Brabant, as well as the most inland known population of A. strenua in Flanders. Details on the habitat and the phenology of the newly discovered population are provided. Furthermore, an overview of the known records and an updated distribution map are given and discussed. We rapporteren de vondst van een nieuwe Belgische binnenlandse populatie van de zeldzame loopkever Amara strenua Zimmerman, 1832. Deze soort werd waargenomen tijdens een onderzoek met bodemvallen in Abdij van Park in Heverlee. Deze opmerkelijke vondst telt zowel als de eerste observatie voor Vlaams-Brabant, als de meest binnenlands gekende populatie in Vlaanderen. Gegevens over de habitat en fenologie van deze ontdekte populatie worden gegeven. Verder wordt een overzicht van de gekende records gemaakt en besproken, samen met een aangepaste verspreidingskaart. Résumé Une nouvelle population du rare scarabée terrestre Amara strenua Zimmerman, 1832 est mentionnée en Belgique. L'espèce a été observée lors d'un inventaire à Abdij van Park (Heverlee). Cette observation constitue le premier signalement de l'espèce dans le Brabant flamand et sa localisation la plus à l'intérieur des terres en Flandre. Des informations détaillées sur l'habitat et la phénologie sont fournis. En outre, une carte de distribution actualisée et un compte rendu des observations sont donnés et discutés. Introduction Amara strenua is an 8-10 mm long ground beetle (Carabidae) (Fig. 1). It is characterized by a metallic green or bronze dorsal coloration and trifurcate protibial spur. It can be identified reliably by the unique shape of the male genitalia. A. strenua most closely resembles A. tricuspidata, but can be differentiated by a deeper groove-shaped basal impression on the pronotum and a narrower pronotum posteriorly in A. tricuspidata. The male genitalia of A. strenua are distinctive, missing lateral indentations on the aedeagus (MUILWIJK et al., 2015)

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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

Additional material examined. 7 specimens: “ Panama: Panama, Campana, / cascade below Anam office, / 270m, 19.vi.2007, / 08.40.818N 079.54.075W, / Balke (PAN 07) [p]” (CKSB, NMPC, ZSMG). Diagnosis. Small, ovoid-shaped species, only slightly attenuated posteriorly; lateral outline nearly continuous between pronotum and elytra in dorsal aspect (Figs 2 A–B). Surface shiny. Elytron rufopiceous with two testaceous maculae; subbasal macula transversely quadrangular, longitudinally extended at lateral margin, narrower basomedially, not reaching suture; posterior macula longitudinal-oblique, expanded medially in apical half, reaching elytral apex. Head finely reticulated and punctate. Pronotum widest at base; lateral bead distinct; finely punctate over entire surface, basal striae sinuated, distinctly curved inwards near base, length about 0.60× length of pronotum measured along same line as stria. Elytra with basal striae straight, slightly shorter than those on pronotum; sutural striae absent; epipleura with moderately oblique humeral carina. Metaventrite sparsely and rather finely punctate over entire surface; metacoxal plates with punctate medial and lateral portions, broadly impunctate along anterior and posterior margins (Fig. 2C). Abdominal ventrites I and II coarsely punctate; ventrite VI unmodified. Median lobe in lateral view expanded medially, apical third linear with lateral margins convergent to acute apex (Fig. 2E); in ventral view with attenuation in apical fifth, then evenly convergent to obtusely pointed apex; ventral surface in apical part with numerous scale-like setae (Fig. 2D). Lateral lobe with apical segment almost straight and parallel-sided, apex slightly protruding (Fig. 2F). Neoclypeodytes curtulus is easily distinguished from the other two Panamanian species by the smaller body size (TL: 1.65–1.80 mm; TL-h: 1.45–1.60; TW: 0.90–1.00 mm), characteristic elytral color pattern (Figs 2 A–B), and the male genitalia with the median lobe expanded medially, and the apex of the lateral lobe protruding but less distinctly than in N. fortunensis sp. nov. (Figs 2 D–F). Note. Miller (2001) describes the subbasal elytral maculae as triangular in N. curtulus, which is however not completely accurate: although the macula is usually somewhat attenuated basomedially, it is never acute triangular (cf. Figs 2 A–B). Collection circumstances. The recently collected specimens were found together with N. balkei sp. nov. (see above). Distribution. The species was described and known so far only from two islands in Pacific Gulf of Panama; here we present the first record from continental Central Panama (Fig. 6).Published as part of Scheers, Kevin & Hájek, Jiří, 2020, Neoclypeodytes Young from Panama, with description of two new species (Coleoptera: Dytiscidae: Hydroporinae: Bidessini), pp. 245-256 in Zootaxa 4890 (2) on page 249, DOI: 10.11646/zootaxa.4890.2.5, http://zenodo.org/record/430186
