    Im Rahmen der floristischen Bestandsaufnahme für die „Flora des Kyffhäusergebirges und der näheren Umgebung“ (BARTHEL & PUSCH, erscheint voraussichtlich 1999) und für die „Flora von Sachsen-Anhalt“ untersuchten die Verfasser in den letzten Jahren auch die Gefäßpflanzen im Umfeld von Tilleda (Landkreis Sangerhausen). Dabei wurde das Untersuchungsgebiet so ausgewählt, daß sich alle nachfolgend genannten Fundortsangaben auf den Meßtischblatt-Quadranten 4532/4 (MTB Kelbra) beziehen

    Zur floristischen Situation des salzbeeinflußten Gebietes zwischen Riethnordhausen und Hackpfüffel

    Get PDF
    Im Landkreis Sangerhausen, MTB 4533/34, zwischen Hackpfüffel und Riethnordhausen, nur wenige Kilometer nordöstlich des Kyffhäusergebirges, befindet sich innerhalb eines Feuchtwiesenkomplexes eine kleinere Salzwiese mit zahlreichen bemerkenswerten Salzpflanzen (Halophyten). Dieser Wiesenkomplex wird im Süden von einem Schilfmantel, im Norden von der Straße Hackpfüffel - Riethnordhausen und im Osten von einem Pappelhain begrenzt (siehe Karte, Teilgebiet 1). Er liegt im nördlichen Teil des einstweilig gesicherten NSG ”Hackpfüffler See”. Hier kam es infolge Subrosion unterlagernder Zechsteinschichten zur Bildung zahlreicher Erdfälle, die heute mit Wasser gefüllt sind. Weitere, mehr oder weniger salzbeeinflußte Wiesenflächen und Gräben finden wir nördlich der Straße Hackpfüffel - Riethnordhausen (Teilgebiet 5 und Graben 6) aber auch östlich des Pappelhaines bis zu den Riethnordhäuser Kleingärten (Teilgebiete 2, 3 und 7) und damit außerhalb des Naturschutzgebietes. Einige halophile Pflanzenarten kommen auch außerhalb unseres eigentlichen Bearbeitungsgebietes, im Umfeld des nahen Hackloches am Südwestrand von Riethnordhausen, vor

    Schutz der Ackerwildkräuter in Thüringen - Eine Erfolgsgeschichte des Naturschutzes

    Get PDF
    Der Anbau von Feldfrüchten wird durch Pflanzen beeinträchtigt, die ohne bewusstes Zutun des Menschen auftreten und zu einer Minderung der Erträge führen können. Derartige Kräuter und Gräser werden allgemein als Unkräuter bezeichnet. Die Definition der Unkräuter als unerwünschte und Schaden verursachende Pflanzen erweist sich als einseitig wirtschaftsorientiert. Unter ökologischen Aspekten handelt es sich um Pflanzen, die zusammen mit den Nutzpflanzen auftreten und in ihrer Lebensweise und ihren Standortansprüchen den Kulturpflanzen angepasst sind

Standing pilosity as described in workers.</p> <p>The male is unknown.</p> <p> <b>Differential diagnosis.</b> Workers of <i>Temnothorax alienus</i> show the typical <i>nylanderi / parvulus</i> -like petiolar shape (Fig. 6 & 7), but differ from the latter in lacking a metanotal impression or groove. The colour of <i>T. alienus</i> is uniformly light yellow-orange, with only a slightly darker broad band on the first gastral tergite. Other Italian <i>Temnothorax</i> are dark brown to black, or have distinctly darker antennal clubs, or if yellow, they have a shining surface.</p> <p> Other species that are similar to <i>Temnothorax alienus</i> and lack a metanotal groove are <i>T. tianshanicus</i> (Tarbinsky 1976), <i>T. satunini</i> (Ruzsky, 1902), an unidentified species from Morocco, <i>T. luteus</i> (Forel 1874), <i>T. rabaudi</i> (Bondroit, 1918), and <i>T. italicus</i> (Consani & Zangheri, 1952). The central Asian <i>T. tianshanicus</i> has longer scapes, broader head, and shorter propodeal spines than <i>T. alienus</i>. The head dorsum of <i>T. tianshanicus</i> is more shining. In addition, <i>T. tianshanicus</i> sometimes has a faint metanotal depression. Other characters are similar, thus <i>T. tianshanicus</i> is morphologically the closest to <i>T. alienus</i>.</p> <p> <i>Temnothorax satunini</i> (Fig. 4 & 5), a species from southern to eastern Turkey and Caucasus, is also morphologically similar, but differs in the following characters: narrower and shining, nearly unsculptured head; yellow colour without darker gaster, and often distinctly shorter propodeal spines (PSL/ML <0.07).</p> <p> An unidentified <i>Temnothorax</i> species from Morocco (PCAS sp. 27 “ Morocco ”) has distinctly longer scapes, a lower, narrower petiole, and a faint metanotal depression. Additionally, the petiole is truncated and pedunculate. Sculpture and colour are similar to <i>T. alienus</i>.</p> <p> Another lighter coloured species with slightly convex or straight mesosomal dorsum is <i>Temnothorax luteus s.l.,</i> which is distinguishable from <i>T. alienus</i> by longer propodeal spines, broader head, longer scapes, and the distinctly lower, pedunculate and narrower petiole. Sculpture characters are similar to <i>T. alienus</i>, but in <i>T. luteus</i> the whole gaster is yellowish coloured. The taxonomic situation of <i>T. luteus</i> is not clear yet; one can split the taxon into two or more species.</p> <p> The two arboreal species <i>Temnothorax rabaudi</i> and <i>T. italicus</i> (Fig. 10 & 11) are similar in the shape of petiole and mesosoma, and might be confused with <i>T. alienus</i>. However, <i>T. rabaudi</i> and <i>T. italicus</i> differ morphometrically in the length of propodeal spines, and the petioles of both species are distinctly lower and more triangular. The petiolar node apex is more rounded in lateral view, with a straight anterior face. The sculpture of head is more heavily reticulate in both species.</p> <p> Species that have a metanotal groove but otherwise resemble <i>Temnothorax alienus</i> are <i>T. lichtensteini</i> (Bondroit, 1918), <i>T. nylanderi</i> (Foerster, 1850), <i>T. crassispinus</i> (Karawajev, 1926), <i>T. parvulus</i>, (Schenck 1850) and <i>T. flavicornis (</i> Emery 1870).</p> <p> <i>Temnothorax lichtensteini</i> (Fig. 8 & 9) workers can easily be distinguished from <i>T. alienus</i> by their very long and curved propodeal spines, the pedunculate petiole with a more rounded or truncated node, the distinct metanotal groove, and the denser sculpture of the head and other parts of the body. Also <i>T. lichtensteini</i> is smaller. Sometimes the colour is identical to <i>T. alienus,</i> but it is usually darker.</p> <p> <i>Temnothorax nylanderi</i> can be distinguished from <i>T. alienus</i> by its longer propodeal spines and more widely separated frontal carinae. <i>T. nylanderi</i> (Fig. 6 & 7) and <i>T. crassispinus</i> workers are darker, with brownish head and mainly dark brown gaster. They can be distinguished from <i>T. alienus</i> by their distinct metanotal groove, more truncated petiolar node, and evident fine and dense parallel striae on the frons. Sometimes the metanotal groove is less visible or rarely absent in <i>T. lichtensteini, T. nylanderi,</i> and <i>T. crassispinus</i>.</p> <p> <i>Temnothorax parvulus</i> has distinctly longer propodeal spines, a deep metanotal groove, a smaller head, and gradually narrower frontal carinae. In addition, <i>T. parvulus</i> has a less coarse, mainly reticulate sculpture, and a uniform pale yellow colour. <i>T. parvulus</i> is rarely found in south Italy.</p> <p> <i>Temnothorax flavicornis</i> is more common, but is easily differentiated by its 11-jointed antenna, coarser head sculpture, longer propodeal spines, and lower petiole.</p> <p> The gynes of <i>Temnothorax alienus</i> are morphologically similar to <i>T. parvulus</i> or a pale <i>T. nylanderi</i> (Fig. 30 & 31). To distinguish gynes of <i>T. alienus</i> from other <i>Temnothorax</i> species is more difficult than in workers.</p> <p> <i>T. anodontoides</i> 0.63±0.03 0.79±0.02 35</p> <p>(Dlussky & Zabe- (0.57–0.70) (0.76–0.82)</p> <p>lin, 1985)</p> <p> <i>T. nigriceps</i> (Mayr, 0.77±0.02 20</p> <p>1855) (0.72–0.81)</p> <p> Compared to <i>Temnothorax alienus</i>, gynes of <i>T. tianshanicus</i> are distinctly smaller, have longer scapes, a narrower head and petiole, a different petiole shape, and a darker colour. <i>T. satunini</i> differs in the shorter propodeal spines, in shorter and narrower head, and narrower mesosoma, but sculpture and colour are equal. In <i>T. luteus</i> the scapes and propodeal spines are longer, and the petiole is pedunculate and distinctly lower. Nearly the whole mesonotum and scutellum is strongly longitudinally rugose, whereas in <i>T. alienus</i> the surface is mainly unsculptured and shiny. In southern Italy, <i>T. luteus s.l</i>. is brownish and strongly sculptured. Gynes of <i>T. rabaudi</i> and <i>T. italicus</i> have tooth-like propodeal spines and a distinctly lower petiole. In both species the head is densely reticulate. Gynes of <i>T. lichtensteini</i> are dark ferrugineous to brown, distinctly smaller, with larger eyes, and longer propodeal spines. <i>T. nylanderi</i> has a narrower petiole in comparison with the postpetiole, darker head, and the same striation of frons as described in workers. <i>T. crassispinus</i> has distinctly longer propodeal spines. Sculpture and colour are similar to <i>T. nylanderi</i>, but <i>T. crassispinus</i> is generally darker than <i>T. alienus</i> and <i>T. nylanderi</i>. The gyne of <i>T. parvulus</i> has a smaller head, larger eyes, longer propodeal spines, and a narrower petiole in comparison with the postpetiole. The colour of <i>T. parvulus</i> is sometimes uniformly yellowish-testaceous including the gaster, in contrast to the more ferrugineous gynes of <i>T. alienus</i>, but usually <i>T. parvulus</i> has brownish coloured gynes. <i>T. parvulus</i> also has a more pedunculate petiole than <i>T. alienus</i>, yet they are very similar and most safely distinguished by morphometric characters.</p> <p> <i>T. affinis</i> (Mayr, 1855)</p> <p> <i>T. nigriceps</i> (Mayr, 1855)</p> <p> <i>T. anodontoides</i> (Dlussky & Zabelin, 1985)</p> <p> <i>T. tuberum</i> (Fabricius, 1775) 0.69±0.02</p> <p>(0.63–72)</p> <p>continued.</p> <p> <b>Comments.</b> Some of the <i>Temnothorax alienus</i> nests were collected in a forest with <i>Quercus</i> and <i>Laurus</i> trees, at the base of a hill. The ground was covered with rocks and ivy. Nests were located in dead sticks on the ground. A second locality where specimens were collected had sparse vegetation with scattered <i>Castanea</i> and <i>Corylus</i> trees.</p> <p> An unpublished cytochrome oxidase (CO 1) analysis (Pusch <i>et al</i>.) supports the hypothesis that <i>T. alienus</i> is not related to the <i>T. nylanderi / parvulus</i> complex, but is phylogenetically closer to <i>T. unifaciatus</i> or <i>T. luteus</i>.</p>Published as part of <i>Schulz, Andreas, Heinze, Jürgen & Pusch, Katja, 2007, Description of two new Te m n o t h o r a x species (Hymenoptera: Formicidae) from Italy, pp. 1-14 in Zootaxa 1471</i> on pages 3-12, DOI: <a href="http://zenodo.org/record/176690">10.5281/zenodo.176690</a&gt
