T1  - Regional distribution, developmental changes, and cellular localization of CNTF-mRNA and protein in the rat brain
N2  - Ciliary neurotrophic factor (CNTF) is a potent survival molecule for a variety of embryonic neurons in culture. The developmental expression of CNTF occurs clearly after the time period of the physiological cell death of CNTF-responsive neurons. This, together with the sites of expression, excludes CNTF as a target-derived neuronal survival factor, at least in rodents. However, CNTF also participates in the induction of type 2 astrocyte differentiation in vitro. Here we demonstrate that the time course of the expression of CNTF-mRNA and protein in the rat optic nerve (as evaluated by quantitative Northern blot analysis and biological activity, respectively) is compatible with such a glial differentiation function of CNTF in vivo. We also show that the type 2 astrocyte-inducing- activity previously demonstrated in optic nerve extract can be precipitated by an antiserum against CNTF. Immunohistochemical analysis of astrocytes in vitro and in vivo demonstrates that the expression of CNTF is confined to a subpopulation of type 1 astrocytes. The olfactory bulb of adult rats has comparably high levels of CNTF to the optic nerve, and here again, CNTF-immunoreactivity is localized in a subpopulation of astrocytes. However, the postnatal expression of CNTF in the olfactory bulb occurs later than in the optic nerve. In other brain regions both CNTF-mRNA and protein levels are much lower.

T1  - Disruption of the CNTF gene results in motor neuron degeneration
N2  - CNTF is a cytosolic molecule expressed postnatally in myelinating Schwann cells and in a subpopulation of astrocytes. Although CNTF administration prevents lesion-mediated and genetically determined motor neuron degeneration, its physiological function remained elusive. Here it is reported that abolition of CNTF gene expression by homologous recombination results in a progressive atrophy and loss of motor neurons in adult mice, which is functionally reflected by a small but significant reduction in muscle strength.

T1  - Essential function of LIF receptor in motor neurons
N2  - D EVELOPME'iT and maintenance of the mammalian nervous system is dependent upon neurotrophic cytokines. One class of neurotrophic factor acts through rcccptor complexes involving the lowaffinity leukaemia inhibitor y faclor receptor subunit (LlF-R). Members of this fa mily of cytokines, such as ciliary neurotrophic factor (CNTF) and leukaemia inhibitory factor (LIF), have profound effects on the survival and maintenance of motor neurons, Recently it was reported that mice lacking LlF-R die shortly after birth unlike mice lacking CNTF or LIF which are viable. Here we describe histopathological analyses of lifr mutants tha t reveal a loss > 35% of facia l motor neurons, 40% of spinal motor neurons and 50% of neurons in the nucleus ambiguus. These findings point to the existence of a ligand for LIF-R tha t is required for the normal development of motor neurons in both brainstem nuclei and spinal cord.

T1  - Molecular cloning, expression and regional distribution of rat ciliary neurotrophic factor
N2  - CILIARY neurotrophic factor (CNTF) was originally characterized as a survival factor for chick ciliary neurons in vitro. More recently, it was shown to promote the survival of a variety of otherneuronal cell types and to affect the differentiation of E7 chick sympathetic neurons by inhibiting their proliferation and by inducing the expression of yasoactiYe intestinal peptide immunoreactiyity (VIP-IR). In cultures of dissociated sympathetic neurons from newborn rats, CNTF induces cholinergic differentiation as shown by increased levels of choline acetyltransferase (ChAT.

T1  - Isolation of a yeast artificial chromosome contig spanning the Greig cephalopolysyndactyly syndrome (GCPS) gene region
N2  - Disruption of the zinc finger gene GLI3 has been shown to be the cause of Greig cephalopolysyndactyly syndrome (GCPS), at least in some GCPS translocation patients. To characterize this genomic region on human chromosome 7p13, we have isolated a VAC contig of more than 1000 kb including the GLI3 gene. In this contig the gene itself spans at least 200-250 kb. A CpG island is located in the vicinity of the 5' region of the known GLI3 cDNA, implying a potential promoter region.

T1  - New trophobiotic symbioses of ants with South East Asian bugs
N2  - A trophobiotic relationship between two species of phloem-feeding plataspid bugs and an ant, Meranoplus mucronatus, was discovered on tree trunks in Malaysia. 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.

T1  - Two new myrmecophytic associations from the Malay Peninsula: ants of the genus Cladomyrma as partners of Saraca thaipingensis and Crypteronia griffithii
N2  - In Peninsular Malaysia the trees Saraca thaipingensis (Caesalpiniaceae) and Crypteronia griffithii (Crypteroniaceae) are inhabited by ants. 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.

Bisherige lagerstättenkundliche Untersuchimgen interpretierten die gesamte Lagerstätte als einheitliche, submarin-exhalativ entstandene stratiforme Bildung in Zusammenhang mit ordovizischem basischem Vulkanismus, der in den Rahmengesteinen der Lagerstätte durch die Diabase der anchimetamorphen Randschieferserie bzw. die Prasinite der Prasinit-Phyllit-Serie dokumentiert ist. Diese Vorstellung steht jedoch in deutlichem Widerspruch zu den Ergebnissen neuerer geochemischer und biostratigraphischer Untersuchungen, die für die Diabase und Prasinite eine völlig unterschiedliche Zusammensetzung ergaben und die zeigten, daß die Prasinit-Phyllit-Serie schon im Oberproterozoikum, die erzführenden Schichten im anchimetamorphen Paläozoikum aber erst im Unterdevon sedimentiert wurden. Für eine Klärung der Situation sind weitere Untersuchungen im Bereich der Lagerstätte erforderlich.

T1  - Ein pflanzensoziologisches Modell der Schattentoleranz von Baumarten in den Bayerischen Alpen
T1  - A Phytosociological Model of Shade Tolerance of Tree Species in the Bavarian Alps
N2  - The ecological niche, as a summary of the environment in which a tree species can live, is a central concept in vegetation ecology and its application in silviculture. While the fundamental niche focusses on the physiological constraints of survival and growth, the realised niche takes competition in real communities into account. To understand realised niches in a causal fashion requires knowledge of the life cycle of plant species. The concept of regeneration niche is based on the notion that establishment and juvenile growth are particularly sensitive stages. Obviously, silviculturalists must be particularly interested in regeneration niches. The database BERGWALD contains 4,934 phytosociological plots from mountain forests and related vegetation types of the Bavarian Alps. The detailed information on plant species composition (trees, tree regeneration, shrubs, herbs and bryophytes) and cover has so far been used extensively for deriving vegetation units, site types and groups of indicator species. In the present study the database content was analysed with regard to the ecology of tree species in general and their regeneration niche in particular. The availability of light as a crucial resource that changes during forest succession was estimated by calculating average Ellenberg indicator values (mL) based on total field and bryophyte layer composition. The relative frequency of plots across the mL gradient in the total database was juxtaposed to the occurrence of the 16 most common tree species in the tree and in the regeneration layer, respectively. [...] As expected, the realised niches of tree species on the light gradient corresponded broadly to Ellenberg's L-value of tree regeneration. As the regional climax, Abies alba and Fagus sylvatica have coincident optima of tree layer and juvenile occurrences in closed, mature stands. Ulmus glabra and Fraxinus excelsior, as species of lower altitude, exhibit niches most similar to these climax species, followed by Acer pseudoplatanus and Picea abies, two of the most frequent species, that occur from low elevations to the timber line. The intermediate role of these four species is confirmed, as regeneration occurs mostly at light levels higher than those found under adult trees of the same species. Against expectations, Taxus baccata clearly prefers stands with moderate to high light, as do Sorbus aria, Sorbus aucuparia and Alnus incana. While Larix decidua and Pinus cembra occupy very similar overall niches, tree layer and regeneration niches of Larix differ markedly, whereas coincident layer niches in Pinus cembra underpin its status as a climax species at tree line. Pinus sylvestris and Salix eleagnos are typical shade-intolerant pioneers, of which regeneration is practically restricted to non-forest vegetation. Pinus rotundata and Juniperus communis are small trees that are entirely restricted to open stands subject to geomorphological activity. The results demonstrate the potential of phytosociological databases for studying the niches of tree species. To be sure, such analyses are no replacement for physiological and experimental studies. The research community is invited to use this source as a reference framework and an empirical validation for more specialised research.

T1  - Iconography of the Genus Hieracium in central Europe - Part 1: General Description and Morphotypes
N2  - The genus Hieracium comprises more than one thousand sexual and apomictic species in Europe, with numerous intermediates and microspecies. 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.

N2  - Die bei Schwarz (1949) als R. vertumnalis abgebildeten Pflanzen entsprechen nicht dem Typusmaterial, sondern weichen durch fast kreisförmige Blattspreiten der Schlussblätter und geringe Blattteilung ab. Sie werden hier als R. suborbicularis spec. nov. beschrieben und mit ihrem Blattzyklus und weiteren Belegen abgebildet. Die bekannte Verbreitung erstreckt sich auf Berlin (wohl erloschen), Thüringen und Bayern. Insgesamt ist aufgrund der kleinen Zahl der Populationen eine starke Gefährdung anzunehmen.
N2  - In 1949 O. Schwarz published an article on thuringian species of the Ranunculus auricomus complex illustrated with several pictures of the species. However, figure 2, purported to represent Ranunculus vertumnalis, does not correspond with the type material. The specimen depicted in figure 2 of Schwarz (1949) showed almost circular later leaves and lacked the main incisures and, therefore, is described here as R. suborbicularis spec. nov. Details of leaf cycle, cauline leaves and other features are presented. The known distribution includes Thuringia, Bavaria and Berlin (obviously extinct). Due to a restricted number of populations R. suborbicularis is considered to be endangered.

T1  - Vegetation und Böden alter und junger Kalkmagerrasen im Naturschutzgebiet "Garchinger Heide" im Norden von München
T1  - Vegetation and soils of ancient and young calcareous grasslands in the nature reserve "Garchinger Heide"
N2  - Das Naturschutzgebiet "Garchinger Heide" ist ein Relikt der ehemals ausgedehnten Kalkmagerrasen auf Pararendzinen über Niederterrassenschotter im Alpenvorland. Bei jahrhundertelanger extensiver Landnutzung hat sich auf trockenen nährstoffarmen Böden eine artenreiche Vegetation mit zahlreichen seltenen und gefährdeten Arten entwickelt. Die "Altheide", welche den größten Teil des Naturschutzgebiets einnimmt, ist geprägt durch flachgründige, nährstoffarme Böden, welche eine geschlossene Vegetation mit einem hohen Anteil an Arten der Halbtrockenrasen (hauptsächlich Mesobromion erecti und Cirsio-Brachypodion) tragen. Das 1945 durch Oberbodenabtrag begonnene, aber nicht mehr ausgebaute und verwendete „Rollfeld“ weist einen niedrigen Feinbodenanteil, welcher auf eine geringe Wasserverfügbarkeit schließen lässt, sowie niedrige Gehalte an Gesamtstickstoff und CAL-austauschbaren P2O5 auf. Die Vegetation ist lückig mit einem hohen Anteil an Trockenrasenarten (Xerobromion, Sedo-Scleranthetea, Sesleritalia albicantis). Das heutige Vorkommen zahlreicher Arten, welche in früheren Untersuchungen (1956 und 1986) nicht gefunden wurden, lässt auf eine fortschreitende Sukzession der Vegetation des Rollfeldes hin zu der der Altheide schließen. Der 1959 zum Naturschutzgebiet hinzu gekaufte ehemalige Acker unterscheidet sich immer noch deutlich von der Altheide. Eine allmähliche Annäherung der Standortbedingungen ist jedoch zu beobachten. So sanken die Gehalte an CAL-austauschbarem P_ 2 O_5 und K_2 O im Vergleich zu Werten aus dem Jahr 1993 deutlich ab. Trotz des immer noch hohen Anteils an Grünlandarten (Molinio-Arrhenatheretea) konnten sich im Vergleich zu 1986 mehr Magerrasenarten etablieren.
N2  - The nature reserve "Garchinger Heide" north of Munich (Bavaria, Germany) is a remnant of the formerly widespread calcareous grasslands of the Munich Gravel Plain on dry, nutrient-poor calcaric Regosol soils with low water-storage capacity. Most of the nature reserve is covered by species-rich ancient grasslands with a high proportion of species of the Mesobromion erecti and Cirsio-Brachypodion. At the “Rollfeld”, where topsoil was removed in 1945, vegetation cover is lower and the proportion of species of the Xerobromion, Sedo-Scleranthetea and Seslerietalia albicantis is higher than on the ancient grasslands due to low water-availability and low nutrient contents. In 2003, the number of ancient grassland species, which have successfully established on the topsoil-removal site, was higher than in vegetation descriptions from 1956 and 1986. On an ex-arable field within the nature reserve, which was last ploughed in 1959, several species of the Molinio-Arrhenatheretea were still found in 2003. In comparison to 1986, however, the number of species of the Mesobromion erecti and Cirsio-Brachypodion was higher and the vegetation has become more similar to the ancient grassland vegetation. This positive development was also reflected in the soil analyses; the contents of exchangeable P_2 O_5 and K_2 O in the soil of the ex-arable field have decreased considerably during the last 12 years.

T1  - Morphometrische Analysen zur Variabilität von Prunus spinosa L. - Populationen(Prunoideae, Rosaceae) im mittleren Saaletal, Thüringen
T1  - Morphometric analysis on the variability of Prunus spinosa L. - populations(Prunoideae, Rosaceae) in the central valley of the river Saale, Thuringia
N2  - Prunus spinosa L. (Rosaceae) is one of the most widespread members of the genus Prunus in middle europe. Its morphological plasticity resulted in a number of described taxa at subspecific level. Since the early neolithic times, drupes of the plum family are recorded and exhibit already a remarkable diversity in size and form. Here we present a short historical account to the use of P. spinosa and an overview of the different taxonomic treatments. We examined distribution patterns in general and in particular in the central valley of the river Saale (Thuringia) with respect to ecological, edaphic and climatic factors. We assessed within 16 populations the variability of 22 metric and 10 qualitative morphological characters at 7 different locations. Population sites included forest-, way- and fieldsides, as well as lightish pine forests. Pollen fertility did not increase during the flowering period, all flowers were directly fully fertile from the beginning. In contrast, glucose content varied significantly depending of the status of fertilization. Epicuticular wax structure was without variation amongst the populations. P. spinosa leaves are covered with a smooth layer of slightly striated wax. Morphological characters were scored on 270 branches and 506 fruits. Most of the characters showed enormous variability among and within populations such as metrics of leaves, thorns and character states of flower morphology. The lowest variability among populations and therefore not dependend of modificatory factors was found in fruit characters. Since kernel morphology seems to be genetically rather than modificatory controlled, we applied the 3 taxonomical concepts of Werneck, Kühn and Scholz u. Scholz to identify evolutionary units at subspecific levels. However, population variability was still so high, that from our study here we can not support an infraspecific classification of Prunus spinosa L.

T1  - Ökologie der Weißtanne (Abies alba Mill.) im bayerischen Alpenraum
T1  - Ecology of silver fir (Abies alba Mill.) in the Bavarian Alps
N2  - Based on queries of the phytosociological databank BERGWALD, a compilation of 3.504 forest vegetation plots from the Bavarian Alps, the ecological niche of Abies alba is re-assessed. The tree species occurs mostly admixed in mountain forests with Fagus and Picea rather than forming distinctive communities of its own. Climatically, Abies is widely distributed to the upper limit of the montane belt, but occurs only sparsely in subalpine forest. Analysis of Ellenberg indicator values based on total species composition yielded the following results: As a tolerant species Abies regeneration has a marked preference for shady forest, which in turn Abies tree layers themselves help create. It also has a clear preference for acidic topsoil conditions. Sites with low N-supply, such as early successional stages on raw carbonate soils, are rarely colonised by Abies. Also, dry and markedly wet forest sites in the region are avoided by Abies. Permutation-based indicator species analysis found a large number of common forest species as being significantly associated with Abies and its frequent companion Fagus sylvatica, whereas there is a negative relationship with more specialised Seslerion and Erico-Pinion species. As Abies alba has very few specific companion species not shared with either Fagus or Picea, the delimitation of Abietetum-syntaxa appears mostly motivated by ecological rather than phytosociological considerations. As a result of its susceptibility towards game browsing, Abies regeneration is an indicator of high woody species richness. The study broadly confirms Abies alba's status as a climax species intermediate between Fagus and Picea, and demonstrates the potential of large phytosociological databanks for niche modelling.

T1  - 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
N2  - Maize seedlings contain high amounts of glucosidically bound 2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one (DIMBOA). The effects of DIMBOA on the feeding behaviour and performance of two noctuids, Spodoptera exigua Hübner and S. frugiperda Smith, were compared. The question was raised whether S. frugiperda, preferring maize and other Poaceae, is better adapted to DIMBOA than S. exigua. 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. Strong detrimental effects of DIMBOA were found on the mycelial growth of the pathogen S. turcica.

T1  - Neue und wieder entdeckte Hieracien auf Rügen
T1  - New taxa and rediscovered hawkweeds on the island of Rügen, Germany
N2  - The island of Rügen (Rugia), located in the Baltic sea, is the most northeastern (NE) part of Germany. Due to its particular geographic position at the border between scandinavian, middle european and continental european floral elements, Rügen harbours several hawkweed species (Hieracia) of the scandinavian area such as Hieracium fuscocinererum, H. subramosum, H. subrigidum and H. diaphanoides subsp. neoornatum and, at the same time, is the most northwestern location of H. echioides. Two endemic Hieracium species have been identified recently, i. e. H. muorum subsp. rugianum and H. caesium subsp. zabelianum (Gottschlich et al. 1998, Bot. Rundbr. Mecklenburg-Vorpommern 31:1-94). In the present communication, two further novel endemic Hieracium taxa will be described, which are restricted to the chalk cliffs of Cape Arkona and Jasmund, i. e. H. swantevitii and H. lachenalii subsp. litocretaceum. H. swantevitii (Swantevit’s hawkweed) is intermediate between H. caesium/H. bifidum and H. lachenalii with hairy, modestly glandular involucre and slightly serrated elongated leaves . This view of an intermediate position of H. swantevitii between these species was further supported by the ultrastructure of epidermal papillae of the outer bracts of the involucre visualized by scanning electron microscopy. H. lachenalii subsp. litocretaceum (chalk cliff hawkweed) is characterized by its narrow anguste to almost linear denticulate leaves in combination with mode rately glandular heads. In addition to the description of these two new hawkweed taxa , the rediscovery of three further species will be reported for Rügen, i. e. H. echioides (W. Gager in SE Rügen), H. cymosum subsp. cymosum (close to Göhren in SE Rügen) and H. subrigidum E Glowe in N Rügen. The locality of H. echioides appears to be most north-western site in middle Europe, the locality of H. cymosum is one of the last growth sites in the northern German lowlands and H. subrigidum (so far only known as a single herbarium specimen, collected 1858 in Rügen) has so far not been recorded in other localities of middle Europe.

T1  - The effects of laser illumination and high energy electrons on molecular-beam epitaxial growth of CdTe
N2  - We report the results of a detailed investigation on the Te-stabilized (2 x 1) and the Cdstabilized c( 2 X 2) surfaces of ( 100) CdTe substrates. The investigation demonstrates for the first time that both laser illumination and, to a greater extent, high-energy electron irradiation increase the Te desorption and reduce the Cd desorption from ( 100) CdTe surfaces. Thus it is possible by choosing the proper growth temperature and photon or electron fluxes to change the surface reconstruction from the normally Te-stabilized to a Cd-stabilized phase.
