Zur Flora in der Umgebung von Tilleda (MTB 4532/4)

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

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

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

Remarcable occurrences of Orobanche artemisiae-campestris Vaucher ex Gaudin and Orobanche bohemica Čelak. have been detected in Thuringia and Saxony-Anhalt (Germany)

Es werden zwei bemerkenswerte Orobanche-Funde in Mitteldeutschland vorgestellt. Zum einen wird über einen Fund der in Sachsen-Anhalt seit Jahrzehnten verschollen geglaubten Panzer-Sommerwurz (Orobanche artemisiae-campestris) bei Wendelstein und zum anderen über einen weiteren Thüringer Nachweis der Böhmischen Sommerwurz (Orobanche bohemica) bei Hemleben berichtet.It is reported on two remarkable findings of Orobanche species in central Germany. Orobanche artemisiaecampestris considered as missing in Saxony-Anhalt since decades was found close to Wendelstein. Furthermore there was found a new stand of Orobanche bohemica close to Hemleben in Thuringia

Description of two new Temnothorax species (Hymenoptera: Formicidae) from Italy

We describe two species of the ant genus Temnothorax: T. alienus nov. spec. and T. saxatilis nov. spec. Both new species are endemic to middle and southern Italy. We characterize the two species and compare them to similar Temnothorax from Italy and the Western Palaearctic

Dorsum of propodeum and surface between the spines transversely carinate. Petiole rugoreticulate, with transverse strigae on dorsum, dorsal petiolar surface and entire postpetiole irregularly reticulate. Dark brown, unicoloured, with the gaster somewhat lighter testaceus to brown. Appendages orange-brown, darker scapes, antennal clubs, and femora. Differential diagnosis. The workers of T. saxatilis are distinguishable from most Italian Temnothorax by the brown colour in combination with a conspicuously truncated and robust petiole. In comparison to T. saxatilis, T. nigriceps (Mayr, 1855) (Fig. 14, 15, 24) has longer scapes and is usually bicoloured with ferruginous mesosoma and waist and contrastingly darker head and gaster. Additionally, the sculpture is much rougher and more visible especially on the head and mesosoma. Workers of T. tuberum (Fabricius, 1775) (Fig. 16, 17, 25) always have a distinctly lighter mesosoma and head, and also stronger sculpture on dorsal head surface, than in T. saxatilis. Other Mediterranean dark coloured Temnothorax species are T. laestrygon (Santschi, 1931), T. niger (Forel, 1894) and the usually lighter, but sometimes equally dark coloured T. exilis (Emery, 1869). The petiole of all three species is lower, triangular, and with a more or less distinct apical crest in lateral view. Furthermore, these species occur only at lower elevations with Mediterranean climate. The arboreal species T. affinis (Mayr, 1855) (Fig. 20 & 21) is similar, when specimens are darker than usual, but they differ by distinctly longer propodeal spines. Very rarely specimens of T. affinis may have shorter spines in combination with darker reddish brown colour. In such cases, these specimens have a more triangular petiolar node and a more evenly reticulate head, without superimposed rugae. A morphologically similar species outside Italy is the tentatively determined T. anodontoides (Dlussky & Zabelin, 1985) (Fig. 18 & 19) from Transcaucasia and a probably isolated population on high mountains of southern Greece. Temnothorax anodontoides from Greece can be distinguished from T. saxatilis by longer scapes, shorter propodeal spines, lower waist (Table 3) dark brown to nearly black colour, coarser rugose sculpture, and truncated, weakly rounded dorsum/apex of petiolar node. For comparison only one gyne of T. saxatilis is available. The gyne of T. nigriceps has longer propodeal spines, more triangular petiolar node in lateral view, and more coarsely sculptured head and mesosoma. Temnothorax tuberum is a morphologically variable species, but has a smaller head and somewhat shorter propodeal spines. Furthermore, in T. tuberum, the mesosoma and especially the scutellum is more densely rugose, and the legs are evenly yellowish, whereas the legs of T. saxatilis are somewhat bicoloured, mostly brown with ferrugineous patches. The gyne of T. affinis (Fig. 36 & 37) is normally lighter coloured than in T. saxatilis, but darker specimens occur. The propodeal spines are usually longer and the petiole is lower in profile. Head sculpture of T. affinis (Fig. 37) is more reticulate and less rugulose, than in T. saxatilis. The brownish to black gynes of T. exilis, T. laestrygon and T. niger are distinctive in their low petiole with a triangular and acute petiolar node in profile. The morphometric differentiation of gynes of T. saxatilis and T. anodontoides from Greece is difficult; only one gyne each is available for comparison. Temnothorax anodontoides has a distinctly lower and truncated petiolar node in profile. In addition, in this species the sculpture is mainly rugose and coarser.Published as part of 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 on pages 12-13, DOI: 10.5281/zenodo.17669
