Dapsa nigripennis Esser 2019
No full text<i>Dapsa nigripennis</i> REITTER, 1879 stat.rev. (Abb. 1, 3) <p>M a t e r i a l u n t e r s u c h t: Türkei: Prov. Sinop [ZMB, cES].</p> <p> Das Taxon <i>Dapsa nigripennis</i> REITTER, 1879 wurde von AUDISIO & DE BIASE (1996) mit <i>Dapsa limbata</i> MOTSCHULSKY, 1835 synonymisiert (Abb. 2, 4). Die Grundlage dafür waren ein als <i>limbata</i> MOTSCHULSKY gedeutetes Weibchen aus der nordwestlichen Türkei (Umg. Bolu) und ein weiteres Weibchen (der Typus von <i>D. nigripennis</i> REITTER) aus der Umgebung der heute Gjumri genannten armenischen Stadt (ehemals Alexanderhilf, Alexandroupolis oder Leninakan).</p> <p>Aufgrund einer ähnlich geringen Anzahl von Tieren kamen auch SEMENOV & NIKITSKY (2001) zu keinem anderen Schluss und behielten die Synonymie bei.</p> <p> Da das typische Material beider Arten weiterhin als verschollen gelten muss (<i>D. limbata</i> MOTSCHULSKY) oder nur noch aus einem einzelnen Weibchen besteht (<i>D. nigripennis</i> REITTER - REITTER (1879) nannte allerdings zwei Exemplare), ist auch die hier vorgenommene Revalidierung nicht gänzlich frei von Zweifeln. Doch der Zugriff auf Material (inkl. männlicher Tiere) aus der Nähe der beiden Typenfundorte lässt das Vorhandensein zweier Arten zweifelsfrei erkennen und eine Anwendung auf die beiden vorhandenen Namen erscheint als die naheliegende Lösung.</p> <p> Der Typenfundort von <i>D</i>. <i>limbata</i> wird von MOTSCHULSKY (1835) mit "sur les montagnes d'Akhalzik en Arménie " angegeben. Die Region liegt heute im Grenzgebiet von Georgien (Provinzen Adscharien und Samzche-Dschawachetien) und der Türkei (Provinzen Artvin, Ardahan und Ezurum). Aktuelles Material liegt aus der weiter westlich gelegenen türkischen Provinz Kastmonu und der weiter östlich gelegenen armenischen Provinz Kotajk vor.</p> <p> Von <i>D</i>. <i>nigripennis</i> REITTER liegt der Typenfundort in der Nähe des heutigen Gjumri in Armenien. Jüngeres Material wurde in der türkischen Provinz Sinop gesammelt.</p> <p> Demnach scheinen beide Arten von Armenien und Georgien entlang der türkischen Schwarzmeerküste nach Westen verbreitet zu sein. AUDISIO & DE BIASE (1996) geben noch die türkische Provinz Bolu an, von wo ihnen ein Weibchen vorlag. Es wäre aber empfehlenswert, männliche Exemplare (so vorhanden) aus dem Nordwesten der Türkei auf die Artgleichheit mit <i>D. limbata</i> MOTSCHULSKY oder <i>nigripennis</i> REITTER zu prüfen, da in anderen Fällen die kaukasischen Arten dort bereits durch verwandte Arten ersetzt werden (ESSER 2017, ESSER 2019).</p> <p>Im Grunde sind beide Arten gut unterscheidbar, v. a. die Männchen mittels Aedoeagus. Bei den Weibchen wie bei Männchen ohne Genitalpräparat bietet der Fühlerbau eine gute Unterscheidungsmöglichkeit (Tab. 1).</p>Published as part of <i>Esser, Jens, 2019, Anmerkungen zur Gattung Dapsa L, 1829 (Coleoptera, Endomychidae), pp. 907-914 in Linzer biologische Beiträge 51 (2)</i> on page 908, DOI: <a href="http://zenodo.org/record/3741910">10.5281/zenodo.3741910</a>
Mediatization of campaign coverage: Metacoverage of US Elections
No full textIf mediatization, like globalization and modernization, is a meta-process of societal change (Krotz, 2008) whereby “the media have become integrated into the operations of other social institutions [and] acquired the status of social institutions in their own right” (Hjarvard, 2008, p. 113), then, arguably, this is nowhere more evident than in contemporary election campaigns. In most Western democracies, there are reciprocal dependencies - mutual need but different goals - between media organizations and the political parties and campaign organizations that vie for votes during elections (Gurevitch & Blumler, 1990). To be sure, the nature of these interdependencies is shaped by structural and cultural features of the media and political institutions within a country (Blumler & Gurevitch, 2001; see Strömbäck & Esser, 2009, pp. 217–218 for a useful summary). However, on the whole, mediatization theorists and researchers are interested in the processes and mechanisms through which these interdependencies typically tilt over time towards the media (Strömbäck, 2008). News organizations lie at the center of interest in work on the mediatization of politics (Esser, 2013). Accordingly, in election settings, the concern is with how the media logic of commercial imperatives, professional routines and message formats not only comes to dominate the content of campaign news, but also how it gets integrated into the political logic of political rules, organizational structures and routines, and self-presentational strategies that political parties and campaign organizations must follow in order to campaign effectively (Strömbäck, 2008; Strömbäck & Esser, 2009)

Microstachys glandulosa Esser & M. J. Silva, comb. et stat. nov.
No full textMicrostachys glandulosa (Mart. & Zucc.) Esser & M.J.Silva, comb. et stat. nov. Basionym:— Cnemidostachys glandulosa Martius & Zuccarini (1824: 139); Martius (1824: 71). — Sebastiania corniculata var. obtusifolia forma glandulosa (Mart. & Zucc.) Müller (1866: 1168).— Sebastiania glandulosa (Mart. & Zucc.) Pax in Pax & Hoffmann (1912: 100).— Sebastiania glandulosa var. obtusifolia forma calvescens Pax in Pax & Hoffmann (1912: 101), nom. inval. Lectotype (designated here): BRAZIL. Minas Gerais: in campis, without date, C. F. P. von Martius s.n. (M-0164455!, isolectotypes M- 0164454!, M-0164456!). Cnemidostachys glandulosa had been overlooked by Esser (1998), and was later listed as synonym of M. corniculata (Vahl) Griseb. by Govaerts et al. (2000: 1186), which was certainly erroneous. It is a separate species, characterized by broadly elliptic to suborbicular, pubescent leaves with an obtuse to rounded (never cordate) base, an obtuse to subacute apex and several distinct marginal glands on the lower surface, which are situated in small lateral lobes that give the leaves a slightly dentate appearance (hence the appropriate epitheton). The species is very similar to M. hispida; the latter species shows, however, elliptic-lanceolate leaves with usually acute to acuminate apex, shoots and twigs are hollow or not in cross section, the fruits are regularly tricarpellate, with conspicuous appendages often pointing upwards, the pubescence is velutinose in addition to hispid and never uncinate hairs, the growth of the plants is erect and never caespitose. M. glandulosa differs from it, in addition the leaf shape, by the stems never hollow, the fruits quite often showing one or two aborted carpels with only vestigial to reduced appendages, the trichomes hispid and often uncinate, and the plants are often caespitose. Among the three type sheets in M, the only one with the original label of Martius is selected as lectotype (the others being duplicates with copied labels), which is also the only one with an annotation label of Müller Argoviensis attached to it. The leaves of the lectotype are slightly larger (30–35 × 13–15 mm) than those of the duplicates (15–25 × 8–12 mm).Published as part of Silva, Marcos José Da & Esser, Hans-Joachim, 2011, Two new taxa and two new combinations in Microstachys (Euphorbiaceae) from South America, pp. 18-26 in Phytotaxa 32 on pages 19-20, DOI: 10.11646/phytotaxa.32.1.2, http://zenodo.org/record/489476

Microstachys stipulacea Esser & M. J. Silva, comb. et stat. nov.
No full textMicrostachys stipulacea (Müll.Arg.) Esser & M.J.Silva, comb. et stat. nov. (fig. 3) Basionym:— Gymnanthes stipulacea Müller (1863: 96).— Stillingia stipulacea (Müll.Arg.) Baillon (1865: 325).— Sebastiania stipulacea (Müll.Arg.) Müller (1866: 1176). Lectotype (designated here): BRAZIL / URUGUAY: Without locality, without date, F. Sellow 3456 (G!, isolectotypes G!, K!, P!). Subshrub to ca. 30 cm tall. Completely glabrous. Leaves: stipules linear, 2–2.5 × ca. 0.4 mm, often persistent; petiole 10 mm long; blade broadly elliptic to suborbicular, 16 × 12 mm, base obtuse, margin shallowly crenate-serrate, apex rounded to subacute, slightly glaucous below, without marginal glands, side veins in 5–6 pairs. Staminate inflorescence 6–7 mm long; bracts c. 0.25 mm long, with a pair of stipitate disc-shaped glands ca. 0.15 mm in diam.; staminate flowers three per bract, their pedicel ca. 0.2 mm long, the calyx ca. 0.12 mm long. Pistillate flowers not seen. Fruits: pedicel ca. 1.3 mm long; capsule ellipsoid, sulcate, ca. 3.2 × 3.2 mm, smooth, with rows of multiple short appendages to ca. 0.7 mm long. This species had been included by Pax & Hoffmann (1912) in their section Elachocroton (F. Müller 1857: 17) Pax & Hoffmann (1912: 114), which is now part of Microstachys. Esser (1998) suggested that it might not belong to Microstachys because of some unusual characters. Study of the type showed, however, that it is a species which is unusual for its long petioles and stipules and for being completely glabrous, but has flowers and fruits typical for Microstachys. Pax & Hofmann (1912) and Govaerts et al. (2000) listed the name ' Microstachys stipulacea (Müll.Arg.) Klotzsch ex Baillon' as a synonym under Sebastiania stipulacea. That name was however never validly published. The herbarium name of Microstachys stipulacea of Klotzsch (who died 1860) predates the publication of Müller (1863), but was only cited as synonym by Baillon (1865). Both Baillon and Müller treated the species under different genera and did not accept the original herbarium name of Klotzsch. The original type collection (Sellow 3456, B) was labelled as being collected in ‘Brasil’, and as such, cited for Brazil by e.g., Pax & Hoffmann (1912). Urban (1893) showed, however, that Sellow’s collection numbers 3331–3623 were collected while travelling from southernmost Brazil into northern Uruguay and back to Alegrete. Therefore the type locality is uncertain. The holotype is lost. There are two type sheets in G. The lectotype chosen here is a poor specimen but with original annotations by Müller. The isolectotype is a better collection, but without original labels (fig. 3). Additional specimens examined:— BRAZIL. ‘Prov. Rio Grande’, 1833 (fl, fr), C.Gaudichaud-Beaupré 1697 (P!); URUGUAY. Without locality, 1816–1821 (fl, fr), A.Saint-Hilaire 2556 (P!, two sheets).Published as part of Silva, Marcos José Da & Esser, Hans-Joachim, 2011, Two new taxa and two new combinations in Microstachys (Euphorbiaceae) from South America, pp. 18-26 in Phytotaxa 32 on page 24, DOI: 10.11646/phytotaxa.32.1.2, http://zenodo.org/record/489476

No full textAs stated in the Introduction, the twofold purpose of this book is first to bring together state-of-the-art chapters on the mediatization of politics, thereby assessing what we know and providing a framework for further research; and second to move research on the mediatization of politics forward towards a more fully developed theory. For this reason, we invited leading scholars in this field to comment in their chapters on basic and more advanced questions and to develop various topics and perspectives. The scope in content and the depth of analysis of their contributions underscore the many different ways in which mediatization research can augment the literature of political communication and how stimulating the impulses are that it evokes
