Saprobic Cladosporium isolates morphologically similar to C. sphaerospermum are phylogenetically analysed on the basis of DNA sequences of the ribosomal RNA gene cluster, including the internal transcribed spacer regions ITS1 and ITS2, the 5.8S rDNA (ITS) and the small subunit (SSU) rDNA as well as beta-tubulin and actin gene introns and exons. Most of the C. sphaerospermum-like species show ha...

The binding selectivity of the M(phen)(edda) (M=Cu, Co, Ni, Zn; phen=1,10-phenanthroline, edda=ethylenediaminediacetic acid) complexes towards ds(CG)(6), ds(AT)(6) and ds(CGCGAATTCGCG) B-form oligonucleotide duplexes were studied by CD spectroscopy and molecular modeling. The binding mode is intercalation and there is selectivity towards AT-sequence and stacking preference for A/A parallel or d...

The asymmetric unit of the title salt, C17H17F6N2O+·C8H7O3-·0.5H2O, comprises a pair of pseudo-enanti-omeric (i.e. related by a non-crystallographic centre of symmetry) piperidin-1-ium cations, two carboxyl-ate anions and a water mol-ecule of crystallization. The cations have similar conformations approximating to a letter, L: one of them shows disorder of its -CF3 group over two sets of sites ...

Observations on functional morphology and results from experiments demonstrate that setiferous epipods compose the major gill-cleaning mechanism in a penaeoid shrimp, Rimapenaeus similis. Epipods on the second maxillipeds and on pereopods 1-3 are equipped with long setae bearing an array of digitate scale setules. These multidenticulate setae reach to most gills and are jostled among them durin...

In the title compound, [Cu(C(10)H(5)O(4))(2)(H(2)O)(2)], the Cu(II) atom lies on a crystallographic inversion center and exhibits an octa-hedral coordination defined by two O atoms from water mol-ecules in the axial positions and by four O atoms from two deprotonated coumarin-3-carb-oxy-lic acid ligands in the equatorial positions. The angles around the Cu(II) atom vary between 85.32 (6) and 94...

Understanding species differences in demographic strategies is a fundamental goal of ecology. In scleractinian corals, colony morphology is tightly linked with many demographic traits, such as size-specific growth and morality. Here we test how well morphology predicts the colony size-fecundity relationship in eight species of broadcast-spawning corals. Variation in colony fecundity is greater ...

We report on digitate and capitate Octocorallia within the genera Parasphaerasclera McFadden & Ofwegen, 2013, Eleutherobia Pütter, 1900, Sphaerasclera McFadden & Ofwegen, 2013, and Paraminabea Williams & Alderslade, 1999 from tropical Western Australian waters. Three new species (Parasphaerasclera kimberleyensis, Eleutherobia australiensis, Eleutherobia imaharai) are described, with a discussio...

The growth cone at the front of a growing neurite often has F-actin-rich structures--digitate filopodia and sheet-like veils and lamellipodia--whose protrusion advances the leading edge. Microtubules and other cytoplasmic constituents later fill the protruded area, transforming it into new neuritic length. Growth can be initiated from an axon by transecting it. We have used video-enhanced contr...

Field investigations at Dugway Proving Ground in western Utah have produced new data on the chronology and human occupation of late Pleistocene and early Holocene lakes, rivers, and wetlands in the Lake Bonneville basin. We have classified paleo-river channels of these ages as “gravel channels” and “sand channels.” Gravel channels are straight to curved, digitate, and have abrupt bulbous ends. ...

Abstract A comprehensive study on the accretion and diagenesis of Permian–Triassic boundary microbialites is conducive to a better understanding ecological community after end-Permian mass extinction. Here we studied special microbialite sequences at Tianba section Leye isolated carbonate platform, South China Block. The are shown as small columnar stromatolites, stromatolitic thrombolites, spo...
