Similar relationships were found between coreid bugs and Crematogaster sp. and Anoplolepis longipes, on bamboo in the same area. The ants recruit to groups of the bugs and feed on the liquid, sugar-rich faeces of the larvae, stimulating release of the honeydew by tactile signals. They protect all stages of the bugs from disturbance by biting and by the use of defensive secretions. Phloem-feeding bugs in the families Plataspidae and Coreidae need long sty lets to pierce the thick bark of their host tree. The different methods of accommodating the resting stylets in these two families are described. The plataspids are described as Tropidotylus servus sp. novo and T. minister sp. novo A coreid previously reported in association with M. mucronatus in Malaya is described as Hygia cliens sp. novo The coreids on bamboo were determined as Cloresmus spp. and Notobitus affinis.}, language = {en} } @article{MorenoDiazdelaEspinaFrankeKrohneetal.1982, author = {Moreno-Diaz de la Espina, Susana and Franke, Werner W. and Krohne, Georg and Trendelenburg, Michael F. and Grund, Christine and Scheer, Ulrich}, title = {Medusoid fibril bodies: a novel type of nuclear filament of diameter 8 to 12 nm with periodic ultrastructure demonstrated in oocytes of Xenopus laevis}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-34116}, year = {1982}, abstract = {No abstract available}, language = {en} } @article{HadjiolovaRoseScheer1986, author = {Hadjiolova, Krassimira and Rose, Kathleen M. and Scheer, Ulrich}, title = {Immunolocalization of nucleolar proteins after D-galactosamine-induced inhibition of transcription in rat hepatocytes}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-33205}, year = {1986}, abstract = {No abstract available}, language = {en} } @article{MaschwitzFialaMoogetal.1991, author = {Maschwitz, Ulrich and Fiala, Brigitte and Moog, J. and Saw, L.

In the vicinity ofGombak, near Kuala Lumpur, the hollow internodes of young Saraca thaipingensis plants are colonized mainly by two Cladomyrma species. In larger trees a Crematogaster sp. is also found. Crypteronia griffithii is inhabited by a third species of Cladomyrma. None of these species is conspecific with any of the three Cladomyrma taxa so far described. The colonies are founded by single mated queens, which have a conspicuous, sphecid wasp-like behaviour when searching for host plants and nest sites. They chew holes into the plant intern odes and hollow them out to provide nest sites. Coccids and pseudococcids are cultivated within the internodes. The homopterans are not carried by queens on their nuptial flights. They apparently find their way by themselves into the cavities or are perhaps carried there by the worker ants. The Cladomyrma ants on Crypteronia are not aggressive, in contrast to those on Saraca thaipingensis. The relationship of Crypteronia with ants seems to be obligatory, whereas Saraca was only partly colonized by Cladomyrma. The interaction of Saraca with Crematogaster sp. is loose and facultative, since the Crematogaster sp. also lives on other tree species. Our studies have now revealed four Cladomyrma spp. which are regularly associated with plants. The genus therefore seems to have an entirely myrmecophytic way of life.}, language = {en} } @article{LillienSendtnerRohreretal.1988, author = {Lillien, Laura E. and Sendtner, Michael and Rohrer, Hermann and Hughes, Simon M. and Raff, Martin C.}, title = {Type-2 Astrocyte Development in Rat Brain Cultures is initiated by a CNTF-like protein produced by type-1 astrocytes}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-31708}, year = {1988}, abstract = {No abstract available}, language = {en} } @article{SchuesslerSkinnerRoland1993, author = {Sch{\"u}ssler, Ulrich and Skinner, David N.

Only a small fraction of the members of the genus Hieracium has been illustrated or photo-documented in the literature. Since many of these publications are difficult to obtain, only a few specialists are familiar with most of the species and subspecies described in the literature. In order to overcome this problem and encourage geobotanical research on the genus Hieracium, we decided to edit an iconography of central and southern European Hieracia in an electronical journal (Forum geobotanicum) with free international access through the internet. Part I of this endeavour contains descriptions and photographs of the morphological spectrum of the genus Hieracium. Here, we categorize the genus into 15 basic morphotypes. These types conform partly to the sections and subsections of the genus Hieracium, but are in some cases informal and may even include members of different sections. Classification of morphotypes is considered helpful to obtain a first rough picture of an unknown species that then can be traced to the species and subspecies level by using keys or, after completion of this iconography, simply by screening the relevant images. One particularly novel aspect of the present endeavour will be the regular inclusion of magnified images and scanning electron micrographs.}, subject = {Habichtskraut}, language = {en} } @article{ArgosDandekar1994, author = {Argos, P. and Dandekar, Thomas}, title = {Delineating the main chain topology of four-helix bundle proteins using the genetic algorithm and knowledge based on the amino acid sequence alone}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-33807}, year = {1994}, abstract = {No abstract available}, subject = {Proteine}, language = {en} } @article{Rostas2007, author = {Rost{\´a}s, Michael}, title = {The effects of 2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one on two species of Spodoptera and the growth of Setosphaeria turcica in vitro}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-35079}, year = {2007}, abstract = {Maize seedlings contain high amounts of glucosidically bound 2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one (DIMBOA).

In addition, the effects of DIMBOA on the mycelial growth of the plant pathogen Setosphaeria turcica Leonard et Suggs (causal agent of northern corn leaf blight) was assessed in vitro. DIMBOA had an antifeedant effect on S. exigua but stimulated feeding in S. frugiperda in dual-choice experiments. In a no-choice setup, larvae of S. exigua gained less biomass and had a prolonged development when feeding on an artificial diet containing DIMBOA. However, pupal weight was not significantly different between treatments. In contrast, larvae of S. frugiperda were not affected by DIMBOA.
