Methodik

Die vegetationskundliche und strukturelle Zuordnung der Lebensraumtypen erfolgt nach der vorrangig von Braun-Blanquet entwickelten Vegetationsklassifizierung, einer hierarchischen Gliederung der Vegetationstypen (Syntaxonomie), die die Ebenen der Assoziation, des Verbandes, der Ordnung und der Klasse umfasst. Hierbei ist die Assoziation die grundlegende Einheit, in der die Pflanzengesellschaften zusammengefasst werden, die sich durch gleiche charakteristische Arten(gruppen)kombinationen auszeichnen. Der Verband vereinigt ähnliche Assoziationen. Das sind bereits umfassendere, jedoch standörtlich noch recht einheitliche Vegetationseinheiten. In Ordnungen werden ähnliche Verbände zusammengefasst. Die Klasse vereinigt ähnliche Ordnungen.
Background: Alzheimer's disease is a common debilitating dementia with known heritability, for which 20 late onset susceptibility loci have been identified, but more remain to be discovered. This study sought to identify new susceptibility genes, using an alternative gene-wide analytical approach which tests for patterns of association within genes, in the powerful genome-wide association dataset of the International Genomics of Alzheimer's Project Consortium, comprising over 7 m genotypes from 25,580 Alzheimer's cases and 48,466 controls.
Principal findings: In addition to earlier reported genes, we detected genome-wide significant loci on chromosomes 8 (TP53INP1, p = 1.4×10−6) and 14 (IGHV1-67 p = 7.9×10−8) which indexed novel susceptibility loci.
Significance: The additional genes identified in this study, have an array of functions previously implicated in Alzheimer's disease, including aspects of energy metabolism, protein degradation and the immune system and add further weight to these pathways as potential therapeutic targets in Alzheimer's disease.
The huntsman spider genera Sparianthina Banks, 1929 and Anaptomecus Simon, 1903 are reviewed. The type species of Sparianthina, Sparianthina selenopoides Banks, 1929, is redescribed, illustrated, and recorded from Costa Rica for the first time; a lectotype and paralectotype are designated. Three species are transferred to the genus: Sparianthina pumilla (Keyserling, 1880) comb. n. from Heteropoda Latreille, 1804 (lectotype and paralectotype are designated), Sparianthina rufescens (Mello-Leitão, 1940) comb. n. from Anaptomecus and Sparianthina milleri (Caporiacco, 1955) comb. n. from Macrinus Simon, 1887. The ♂ of S. rufescens (Mello-Leitão, 1940) comb. n. and the ♀ of S. milleri comb. n. are described for the first time. Three new species are described: Sparianthina adisi sp. n., S. deltshevi sp. n., and S. saaristoi sp. n. The male and female of Anaptomecus longiventris Simon, 1903 are described for the first time and the species is recorded from Panama for the first time. Two new species are described: Anaptomecus temii sp. n. and A. levyi sp. n. Keywords: Taxonomy, re-description, transfer, review
A new species of the basal araneomorph spider genus Ectatosticta (Araneae, Hypochilidae) from China
(2009)
The hypochilid spider Ectatosticta davidi (Simon) is redescribed on the basis of adults from Mt. Taibaishan in Shaanxi Province, China; the specimens from Qinghai Province previously identified as E. davidi by most modern authors belong to a new species described as E. deltshevi. Keywords: Araneae, Araneomorphae, Hypochilidae, Ectatosticta, China
Data and a drawing of the epigyne of Phoneutria boliviensis (F.O. Pickard-Cambridge, 1897), recently recorded from Germany, are presented. The specimen was introduced with cargo (bananas) from Brazil. Characters of the single female are illustrated to facilitate identification in the future, since in the two recent revisions of the genus no drawing of the epigyne of P. boliviensis was included. Another case of introduction from 1998 of an unidentified subadult Phoneutria specimen, probably P. boliviensis too, with bananas from Ecuador is documented.
Europäische Spinne des Jahres 2006: Die Veränderliche Krabbenspinne - Misumena vatia (Clerck, 1757)
(2006)
Mit der letztjährigen Spinne des Jahres, der Zebraspringspinne Salticus scenicus (Jäger & Kreuels 2005) wurde ein Weg beschritten, Europa arachnologisch zu einen. Ziel war es, möglichst viele Länder bei der Wahl einer europäischen Spinne des Jahres zu beteiligen. 2006 hat die Spinne des Jahres diesen Weg erfolgreich weiter verfolgt.
