Typology of the synflorescence of Andropogoneae (Poaceae), additional comments
Authors: Vegetti A. C. 
Published: August 2010

AbstractSynflorescences of the Andropogoneae tribe are studied from a typological point of view.The criteria of CLAYTON & RENVOIZE (1986) were used in order to arrange the subtribes, excluding the former Maydeae as suggested by WATSON & DALLWITZ (1992). 36 taxa from 7 subtribes have been studied; data for other genera from CLAYTON & RENVOIZE (1986) and WATSON & DALLWITZ (1992) have been included for the comparison of the inflorescence structure.In the inflorescence of Andropogoneae specialisations of paracladia were observed which can be characterized as short paracladia and long paracladia.Most short paracladia are of second grade, although there appear some of first degree and third degree in some genera.Some species present long paracladia with prophylls and bracts wereas on others both they are absent. There is a third group of species which has both types of paracladia. It is proposed long paracladia without prophylls and bracts to call long paracladia without trophotagma and long paracladia with trophotagma to call long paracladia with trophotagma.The extent of ramification in the area of long paracladia with trophotagma is amplified by the development of the axillary buds of the prophylls. and bracts with the exception of the generally sterile distal bracts.Possible phylogenetic tendencies in the development of the subzone of short paracladia and the subzone of long paracladia are discussed.

Zur Vegetationsentwicklung naturnaher Flußtalmoore am Beispiel des NSG „Peenewiesen bei Gützkow”︁ (Mecklenburg‐Vorpommern)
Authors: Fischer U. 
Published: August 2010

AbstractZiel dieser Arbeit ist eine Darstellung von Standort und Vegetation für das Naturschutzgebiet (NSG) „Peenewiesen bei Gützkow”︁. Der Vergleich mit früheren Arbeiten und historischen Dokumenten erlaubt Aussagen zur Vegetationsentwicklung in den letzten Jahrzehnten und deren Ursachen. Das Untersuchungsgebiet (UG) ist das bedeutendste Naturschutzgebiet im Bereich der nordostdeutschen Flußtalmoore. Es repräsentiert trotz seiner geringen Größe die charakteristische Vegetationszonierung eines primär mesotroph‐subneutralen Durchströmungsmoores unter extensiven Nutzungsbedingungen. Im UG sind seit 1694 alle Formen typischer historischer Nutzung der Talmoore dokumentiert. Weidenutzung, zweischürige Mahdnutzung, Mergelung, Dränage und Umbruch mit Neuansaat sowie Hand‐ und Maschinentorfstich. Das UG zeigt großen floristischen Reichtum. Elf vom Aussterben bedrohte, 26 stark gefährdete und 31 gefährdete Arten kommen vor. Floristisch besonders reich ist nach wie vor ein talrandnahes, druckwasserbestimmtes Pfeifengraswiesen‐Handtorfstich‐Mosaik mit Resten der Vegetation mesotroph‐kalkhaltiger Moore. Es wurden 27 Vegetationsformen folgender Vegetationsformationen ausgeschieden: Seggenriede, Röhrichte, Feuchtwiesen, Staudenfluren und Staudenröhrichte, Feuchtgebüsche und Bruchwälder. Mittlere Grundwasserstände und Grundwassergang haben sich seit 1975 nicht wesentlich verändert. Aus Oberbodenansprache und Bodenanalysen folgt: Der Norden des UG ist stark, der Süden nur mäßig bis schwach anthropogen beeinflußt. Untersuchungen der Leitfähigkeit der Torfschichten in den oberen zwei Metern verdeutlichen den weit in das Gebiet hineinreichenden Überflutungseinfluß der Peene. Die Maschinentorfstiche entwickelten sich in den letzten 20 Jahren von mesotroph‐alkalisch/eutrophen zu polytrophen Gewässern. Ursachen sind Bewaldung und Überflutung. Die Feuchtwiesen zeigen gegenwärtig eine starke Verstaudungstendenz mit der Ausbreitung von drei Hauptfaziesbildnern. Ursachen sind die unregelmäßige Mahdnutzung der letzten 30 Jahre und Nährstoffeintrag. 40% des UG sind heute von geschlossenem Bruchwald bedeckt. In mesotroph‐grundwasserbestimmten Bereichen betrug der Bewaldungszeitraum weniger als 50 Jahre, im Überflutungsbereich wächst bereits in 20 Jahren ein geschlossener Bruchwald auf. Eine starke Eutrophierungstendenz durch Überflutung prägt die Waldstandorte. Wichtige Pflegemaßnahmen zur Erhaltung von Vegetations‐ und Landschaftsbild sind regelmäßige, mindestens einmal jährliche Mahd der Feuchtwiesen sowie Beweidung von Seggenrieden und offenen Gebüschen.

The cycadalean foliage „Encephalartos”︁ gorceixianus Saporta (Zamiaceae) from the Lower Miocene of Greece (Kymi, Island of Evia) revisited
Authors: Kvaček Z. , Velitzelos E. 
Published: August 2010

AbstractThe holotype and additional specimens of cycadalean foliage known as Encephalartos gorceixianus Saporta from the Lower Miocene of Greece show strong gross morphological similarities to the extant genus Dioon Lindl. (Mexico, Honduras, Nicaragua) as well as the fossil Dioonopsis Horiuchi & Kimura (Palaeogene of Japan, and Alaska), rather than to the African genus Encephalartos Lehm. Because of the lack of the epidermis structure, its generic assignment must remain open. The occurrence of this relict in the Lower Miocene of southern Europe suggests palaeofloristic connections with other parts of the Northern Hemisphere, rather than with Africa.

Structural variation of Tertiary Grewia woods (Tiliaceae) from East Bavarian Molasse, Germany
Authors: Seilmeier A. 
Published: August 2010

AbstractThe problem of anatomical xylem variation of silicified Grewia wood is discussed. Based on 15 wood remains from the Bavarian „Ostmolasse”︁, Rauscheröd locality, it is attempted to explain the variation of the wood structure mainly by the topographic origin of the studied woods within the Tertiary trees or shrubs. Variations of the anatomical character are visible in small wood pieces and even within single slides. Three new samples are described and attributed to Grewioxylon ortenburgense. The silicified Grewia woods have a peculiar ray composition with tile cells. The unusual and rare feature has only 1% occurrence under the extant woody Dicotyledons.

Authors: Stierstorfer Ch. 
Published: August 2010

AbstractHolcus mollis L. subsp. hierrensis is new to science. Its distinct chamaephytic habit and particular features of the morphology of the spikelets, provided in a key, as well as its ecology allow a taxonomic separation from the otherwise similar subsp. mollis. A short survey of important facts about the species given in the literature is presented. The possible status of the new subspecies as a neoendemic of the island of El Hierro (Canaries) is discussed.

Achievements and perspectives of top‐down proteomics
Authors: Armirotti Andrea , Damonte Gianluca 
Published: August 2010

AbstractOver the last years, top‐down (TD) MS has gained a remarkable space in proteomics, rapidly trespassing the limit between a promising approach and a solid, established technique. Several research groups worldwide have implemented TD analysis in their routine work on proteomics, deriving structural information on proteins with the level of accuracy that is impossible to achieve with classical bottom‐up approaches. Complete maps of PTMs and assessment of single aminoacid polymorphisms are only a few of the results that can be obtained with this technique. Despite some existing technical and economical limitations, TD analysis is at present the most powerful instrument for MS‐based proteomics and its implementation in routine workflow is a rapidly approaching turning point in proteomics. In this review article, the state‐of‐the‐art of TD approach is described along with its major advantages and drawbacks and the most recent trends in TD analysis are discussed. References for all the covered topics are reported in the text, with the aim to support both newcomers and mass spectrometrists already introduced to TD proteomics.
Developing biodiversity indicators for cities: applying the DPSIR model to Nagoya and integrating social and ecological aspects
Authors: Kohsaka Ryo 
Published: August 2010

AbstractCapturing the trends and status of urban biodiversity is challenged by current rapid changes, including increasing population flow into urban areas and multiple pressures on neighboring ecosystems. For this reason, this article aims to highlight relevant findings from both ecological and social sciences in the development of urban and biodiversity indicators. It examines the applicability of a model to an urban city in Japan. The objectives of this study are threefold. First, it reviews and summarizes the historical development and relevant existing studies of urban and biodiversity indicators, the “Drivers‐Pressure‐State‐Impact‐Response” (DPSIR) model is presented, and its main critiques are summarized. Second, trends in scientific studies in specific journals are identified. Third, practical lessons for a Japanese local municipality, the city of Nagoya, are derived from two previous sets of reviews. The applicability of the “DPSIR” to current practices in the city of Nagoya is examined to assess the relevance of the model to real situations.
Mountain biodiversity conservation and management: a paradigm shift in policies and practices in the Hindu Kush‐Himalayas
Authors: Sharma Eklabya , Chettri Nakul , Oli Krishna Prasad 
Published: August 2010

AbstractMountains occupy 24% of the global land surface area and are home to 12% of the world's population. They have ecological, aesthetic, and socioeconomic significance, not only for people living in mountain areas, but for those living beyond. Mountains need specific attention for their contribution to global goods and services, especially by developing and implementing mountain specific policies. Conservation policies have evolved from the protection of charismatic species, to habitat and ecosystem/landscape conservation, and, finally, to people‐oriented conservation approaches. This paper, with particular reference to paradigm shifts in the Hindu Kush‐Himalayan (HKH) region, discusses the evolution of conservation policies, developments in conservation practices, the status of protected area management, wetland conservation initiatives and the landscape approach, community‐based conservation initiatives, and the convergence of policies and practices. In the HKH region, conservation efforts now adopt participatory approaches, implement policies of decentralised governance for biodiversity management, and empower local communities in biodiversity management. The paradigm shift in the policies and practices related to conservation has been gradual and has included the acceptance of communities as an integral part of national level conservation initiatives, together with the integration of many global conventions. There are many successful pilots in the HKH region that deserve upscaling by the countries from the region. Realising the importance of mountains as hotspots of biodiversity, and due to their role as providers of global goods and services, the Convention on Biological Diversity adopted the Programme of Work on Mountain Biodiversity. Such a decision specific to mountains provides enormous opportunities for both conservation and development. Recent challenges posed by climate change need to be integrated into overall biodiversity conservation and management agendas, especially in mountain areas. The HKH region has been identified as a blank spot for data by the Inter‐Governmental Panel on Climate Change, indicating the need to develop regional database and sharing mechanisms. This is a tall task, but one that holds enormous opportunity for the HKH countries and institutions with regional mandates to address the emerging challenges of climate change on biodiversity conservation by reducing scientific uncertainty.
Density-dependent effects on parasite growth and parasite-induced host immunodepression in the larval helminthPomphorhynchus laevis
Authors: CORNET STEPHANE 
Published: August 2010

SUMMARYLarval helminths exploit the physiology of their intermediate hosts: first, as a resource for energy and space and second by altering the immune system activity to ensure their survival. Whereas the growth pattern under parasite competition has been investigated, the effect of multiple infections on the level of parasite-induced immunodepression in a trophically transmitted helminth has been neglected. In this study, amphipodsGammarus pulexwere infected in the laboratory by the acanthocephalanPomphorhynchus laevisto investigate how parasite density in the intermediate host affected (i) cystacanth growth and (ii) the level of parasite-induced alterations of the host immune defences, two traits strongly linked to host exploitation. The study highlights that sharing a host is costly. As parasite intensity increases, competition for resources translates into a reduction in cystacanth volume. Immune manipulation is also modulated by density. Interestingly, immunodepression is higher in double-infected hosts compared to hosts with a single infection, suggesting an opportunity for cooperative immune manipulation. However, in higher multiple infections, parasites do not further down-regulate the host immune response, possibly to avoid additional costs that may outweigh the benefits of immunodepression.
High-throughput screening in suboptimal growth conditions identifies agonists ofGiardia lambliaproliferation
Authors: FAGHIRI Z. , SANTIAGO R. BONILLA , WU Z. , WIDMER G. 
Published: August 2010

SUMMARYGiardia lambliais one of the most prevalent parasites of mankind and is estimated to cause over 200 million infections per year. To screen chemical libraries for compounds that perturb trophozoite proliferation we adapted a conventional culture method to 384-well plates and identified numerous inhibitors. Here we used a modified assay to screen for compounds that promote trophozoite multiplication. Trophozoite growth was reduced by dilution of the culture medium and the growth period was extended to screen 2 compound libraries comprising 1500 compounds. A total of 4 agonists of trophozoite multiplication were identified. In the presence of one of these compounds, strychnine, enhanced growth was accompanied by unusual trophozoite morphology characterized by dividing trophozoites displaying more than the 2 nuclei per cell which are normally observed. The other agonists, although belonging to 2 distinct chemical groups, are known to affect isoprenylation, indicating a link between protein or lipid isoprenylation and growth in culture. Although inhibitors of isoprenylation are known to antagonize proliferation of mammalian cells, an agonistic effect of isoprenylation modulators has to our knowledge not been described previously. These observations illustrate the power of chemical genetics for identifying pathways controlling specific traits inG. lamblia.
