Vegetation of Little Bora Nature Conservation Trust Agreement, North Western Slopes, New South Wales
(2014)
The vegetation of the Little Bora Nature Conservation Trust Agreement property (560 ha in area), 8 km south east of Bingara (lat 29° 55’S long 150° 37’) in the Gwydir Shire and within the Nandewar Bioregion is described. Eight vegetation communities are defined based on flexible UPGMA analysis of cover-abundance scores of all vascular plant taxa. These communities are mapped based on ground truthing, ADS40 imagery interpretation, topography and substrate. Communities described are: 1) Melaleuca bracteata – Eucalyptus melanophloia – Eucalyptus camaldulensis Woodland, 2) Callitris glaucophylla – Eucalyptus melanophloia – Eucalyptus albens Woodland, 3) Callitris glaucophylla – Eucalyptus melanophloia – Brachychiton populneus Woodland, 4) Eucalyptus albens Woodland, 5) Eucalyptus caleyi – Eucalyptus albens – Callitris glaucophylla Woodland, 6) Callitris glaucophylla – Eucalyptus melanophloia – Eucalyptus albens Woodland, 7) Austrostipa verticillata – Austrostipa scabra Derived Grassland, 8) Eucalyptus melliodora – Eucalyptus dealbata Woodland. A total of 232 vascular plant taxa were found of which 14% were considered exotic in origin. 66 ha of listed threatened communities were mapped along with populations of a currently listed Extinct plant (TSC Act) Dodonaea stenophylla.
Natural vegetation of freely draining beach sand ridges in the valley of the Upper Myall River on the lower North Coast of NSW is sclerophyllous open forest or woodland. Based on previous experience on the nearby Eurunderee area, the vegetation on the sand ridges was classified into three types. These were mapped using aerial photographs and field observation. In transects, each 50 m long, the presence of species was scored in 10, 5 X 5 m quadrats. 48 such transects were used sampling all three types of vegetation on the sand ridges and also vegetation in periodically waterlogged sites adjacent to the ridges. Data from the transects, subjected to an ordination using principal components analysis, revealed clear separation between vegetation of the ridges and that of periodically waterlogged sites. In the ordination, vegetation of the ridges formed a continuum with the three types occupying characteristic parts of the continuum, reflecting their respective distributions on sands with different geomorphological histories. The most grassy, tallest forest, termed Dry Sclerophyll Forest (DSF) is on sands either recently disturbed or deposited (Holocene) or closely overlying other substrates. Banksia serrata occurs in DSF. The least grassy, most sclerophyllous, lowest forest or woodland, termed Dry Heath Forest (DHF), occurs on sands apparently little disturbed since they were laid down in the Pleistocene. Banksia aemula occurs in DHF. An intermediate forest, in which Banksia aemula and Banksia serrata occur together, Intermediate Dry Forest (IDF), is most widely found on the sand mass close to Bombah Broadwater. This sand is postulated to have been reworked during the last Glacial Period. In short, the vegetation of these sand ridges largely varies with time since they were laid down or last disturbed in a major way. Preliminary observations indicate the degree of podsolization of their soils is similarly related to this variation in time.
Christian Kracht é hoje, se não dos melhores, certamente dos mais comentados autores da ficção de língua alemã. Seu trajeto recua a 1995, ano da publicação de "Faserland", o primeiro romance, que aliás distinguiu as balizas daquela que, nessa década, se chamou "Popliteratur". Mas, seja a hora zero de uma obra composta de outros bons momentos, seja o ponteiro literário de uma geração, "Faserland" não é só exemplo pop, tem merecido constantes leituras, sempre novas tiragens, abordagens críticas e assim também a atenção da historiografia literária. No romance são narrados alguns poucos dias da vida narcotizada de um jovem endinheirado e meio sem rumo, do Norte ao Sul da Alemanha, até a Suíça. Nada extraordinário, nenhuma grande peripécia, nenhuma aventura, senão a impressão de um vazio todo presente e o fastio, força do aborrecimento. No texto, investigo que espécie de aborrecimento produz "Faserland".
Die Nationalsozialisten zerstörten seine Kindheit, raubten ihm die Jugend: Josef Buchmann überlebte die Konzentrationslager. Er gab nie auf, wurde ein erfolgreicher Unternehmer. Nachwuchsforscher und die Wissenschaft zu unterstützen, das sieht er – der selbst nicht studieren konnte – als "sein Lebenswerk" an.
Denkt man an Orchideen, fallen einem zunächst die zahlreichen ornamentalen Wildformen und Zierpflanzen ein. Weniger assoziiert man damit eines der teuersten Gewürze der Welt: die Vanille. Aus der riesigen Familie der Orchideengewächse ist Vanille die einzige Nutzpflanze. Ihr intensives Fruchtaroma lässt sich vielfach einsetzen. Sofern sie nicht synthetisch hergestellt wurden, stammen die bei uns im Handel erhältliche Vanilleprodukte alle von der Echten Vanille (Vanilla planifolia) ab. Der vorliegende Beitrag bietet einen Überblick zu Systematik und Verbreitung, Morphologie und Verwendung der Echten Vanille.
One of the most challenging aspects of RT-qPCR data analysis is the identification of reliable reference genes. Ideally, they should be neither induced nor repressed under different experimental conditions. To date, few reference genes have been adequately studied for sugarcane (Saccharum spp.) using statistical approaches. In this work, six candidate genes (αTUB, GAPDH, H1, SAMDC, UBQ, and 25S rRNA) were tested for gene expression normalization of sugarcane root tissues from drought-tolerant and -sensitive accessions after continuous dehydration (24 h). By undergoing different approaches (GeNorm, NormFinder, and BestKeeper), it was shown that most of them could be used in combinations for normalization purposes, with the exception of SAMDC. Nevertheless three of them (H1, αTUB, and GAPDH) were considered the most reliable reference genes. Their suitability as reference genes validated the expression profiles of two targets (AS and PFPα1), related to SuperSAGE unitags, in agreement with results revealed by previous in silico analysis. The other two sugarcane unitags (ACC oxidase and PIP1-1), after salt stress (100 mM NaCl), presented their expressions validated in the same way. In conclusion, these reference genes will be useful for dissecting gene expression in sugarcane roots under abiotic stress, especially in transcriptomic studies using SuperSAGE or RNAseq approaches.
In der Phraseologieforschung gelten Phraseologismen als solche Einheiten, die an den jeweiligen Kontext angeschlossen werden müssen, da sie "offene Stellen" enthalten, die ergänzt werden müssen. Sie sind also keine fertigen Sätze oder Texte und bedürfen eines Anschlusses an den Kontext (vgl. Fleischer 1997: 80ff. und 1994: 155–172). Das betrifft v.a. verbale Phraseologismen, d.h. solche, die ein Verb in ihrer Struktur beinhalten und somit wie ein Verb in der Sprachgemeinschaft gebraucht werden (vgl. Sternkopf 1992). Das Verb gilt aber immerhin als strukturelles Zentrum des Satzes und ihm kommt die Rolle zu, den gesamten Satz zu organisieren...

Utopia ou distopia? : A ansiedade e o vazio em "Schimmernder Dunst über CobyCounty" de Leif Randt
(2014)
Em "Schimmernder Dunst über CobyCounty" (2011), Leif Randt apresenta um condado que seria a mais perfeita representação de uma utopia consumista: localizado à beira-mar, CobyCounty é um lugar de festas abundantes, consumo e bem-estar. O livro, contudo, é narrado por um jovem atormentado pela possibilidade de uma catástrofe que se aproxima, desde que seu melhor amigo abandonou a cidade, ouvindo os conselhos da mãe que se afiliou a uma religião esotérica. Se a perfeição do funcionamento dessa sociedade se aproxima muito de uma utopia, o temor de uma catástrofe anunciada aproxima a obra de uma distopia. Deve-se notar, no entanto, que, ao contrário de utopias e distopias, a obra não apresenta uma força centralizadora de poder – mesmo que a menção ao consumismo e às propagandas seja frequente. Neste artigo, "Schimmernder Dunst über CobyCounty" será apresentado à luz dos estudos da utopia e distopia, enfatizando seus laços com o tempo atual, marcado pela dicotomia entre a sociedade de conforto produzida pelo alto desenvolvimento tecnológico e a necessidade de se evitar os excessos produzidos por essa mesma sociedade em nome de uma possível catástrofe ecológica, anunciada por cientistas e ativistas, mas da qual não se percebe o impacto diretamente.
U radu se analizira fonološko nazivlje koje se upotrebljava u pravopisima kojima je Klaić bio autor. Nazivlje se uspoređuje s fonološkim nazivljem koje se upotrebljavalo u pravopisima koji su prethodili Klaićevim i u onima koji su napisani nakon Klaićevih. Posebna je pozornost posvećena problemu glasovnih promjena. Utvrđuje se koje se glasovne promjene spominju, koji se nazivi upotrebljavaju te kako se one definiraju.
