FIGURE 8 in São João del Rei is the type locality of Scytalopus speluncae (Aves: Passeriformes: Rhinocryptidae)-a response to Maurício et al. (2010)
No full textFIGURE 8. Male specimens of the Scytalopus speluncae group from Minas Gerais and Bahia, from left to right: MN 42742 from Ibicoara, Chapada Diamantina, Bahia; MN 42607 and 44409 from RPPN Santuario do Caraça, Catas Altas, Minas Gerais; and MN 44013 from São João del Rei, Minas Gerais (topotype). Contrary to what is stated by Mauricio et al. (2010), there is some degree of individual variation within S. speluncae in terms of overall coloration, even within specimens from very close to the type locality of its junior synonym S. petrophilus Whitney et al. 2010.Published as part of Raposo, Marcos A., Kirwan, Guy M., Loskot, Vladimir & Assis, Claydson Pinto De, 2012, São João del Rei is the type locality of Scytalopus speluncae (Aves: Passeriformes: Rhinocryptidae)-a response to Maurício et al.

Paludicolaptes Raposo & Dubois & Kirwan & Assis & Höfling & Stopiglia 2018, genus nov.
No full textPaludicolaptes genus nov. Type species: Dendrornis kienerii Des Murs, 1855. Diagnosis: The genus Paludicolaptes differs immediately from those genera in its putative sister clade (Campylorhamphus and Lepidocolaptes, see Aleixo 2002) by its straight and strong bill, and from all other Dendrocolaptidae by the combination of a straight pale bill and whitish pectoral streaks broadly bordered black or dark brown that generally do not reach the abdomen. It conforms to the usual pattern of Dendrocolaptidae syrinx and skull, differing from other families by presenting a combination of the following characters: Cartt. accessoriae named Processus vocalis with lateromedial projections (horns of the Processi vocales); strong reduction of the tracheal rings (elements) of the Mem. tracheosyringealis region; two pairs of intrinsic muscles (M. vocalis ventralis and M. vocalis dorsalis); and holorhine nares (see Feduccia 1973). According to Raposo et al. (2006), Paludicolaptes differs from other woodcreeper genera (except Xiphorhynchus, Campylorhamphus and Lepidocolaptes) by details of the syringeal elements. Paludicolaptes presents well-marked A elements in the tracheosyringeal membrane, also different from Hylexetastes, Drymornis and Xiphocolaptes where the elements are almost invisible; in Dendrocincla, the B4 element has a larger diameter in relation to B1, B2 and B3, which have identical sizes; Hylexetastes has the A2 element greatly developed and A3 almost absent, which modifications are not observed in Paludicolaptes. From Nasica, Paludicolaptes differs immediately by the number of T elements (vide Raposo et al. 2006)— 12 in Nasica and six in Paludicolaptes. From Deconychura, Certhiasomus and Sittasomus, Paludicolaptes differs in the number of visible elements in the Membrana trachealis, five in those genera and six in Paludicolaptes. Paludicolaptes also differs from Sittasomus and Glyphorynchus by the proportions of the A elements sited caudally on the Membrana trachealis. Paludicolaptes differs from Dendrocolaptes by the extremely large “horns” of the Processi vocales in the latter. The species are further characterized by their habitat choice, shunning the interior of humid forests, in favour of deciduous types, including mangrove and desert formations, where they breed in cacti. Coastal populations inhabit islands in river deltas and mangrove, and, where associated with forested environments, they clearly prefer borders and gallery forests. Phylogeny: Monophyly of the genus Paludicolaptes is corroborated by the molecular phylogeny recovered by Aleixo (2002) which placed it as sister group to that comprising the genera Campylorhamphus and Lepidocolaptes (see Aleixo 2002). Etymology: L. paludicola, “marsh-dweller” < palus, paludis, “swamp”; cola, “dweller” < colere “to inhabit”; Gr. Koλαπτης, kolaptēs, “chiseller” <κoλαπτω, kolaptō, “to chisel, to peck, to strike”. This nomen points to the ability of the species P. picus and, especially, of its type species P. kienerii, to occupy water-associated habitats, like igapós. Paludicolaptes picus is also commonly present in mangroves and gallery forests. Grammatical gender: Masculine. Species included: Based on our taxonomic analysis, Paludicolaptes contains at least three species, those already widely considered valid, namely Paludicolaptes picus (J. F. Gmelin, 1788) and Paludicolaptes kienerii (Des Murs, 1855), as well as Paludicolaptes picirostris (Lafresnaye, 1847). Although the last species has been considered a subspecies in virtually all of the literature and species lists since Peters (1951), no formal revision has justified this treatment. A more comprehensive review points to its validity as a species (Raposo et al. in prep.).Published as part of Raposo, Marcos A., Dubois, Alain, Kirwan, Guy M., Assis, Claydson Pinto De, Höfling, Elizabeth & Stopiglia, Renata, 2018, Synonymization of the genus nomen Dendroplex Swainson, 1827 and description of a new genus of woodcreeper (Aves: Passeriformes: Dendrocolaptidae) with remarks on Articles 67.5 and 70.3 of the Code, pp. 561-566 in Zootaxa 4532 (4) on pages 564-565, DOI: 10.11646/zootaxa.4532.4.7, http://zenodo.org/record/261568

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
