BACKGROUND AND AIMS Plant parasitism and arbuscular mycorrhizal (AM) associations have many parallels and share a number of regulatory pathways. Despite a rapid increase in investigations addressing the roles of AM fungi in regulating interactions between parasitic plants and their hosts, few studies have tested the effect of AM fungi on the initiation and differentiation of haustoria, the para...

Viola is a tool for the development and support of visual interactive media applications. Possible viola applications range from a simple clock to a World Wide Web hypermedia browser (ViolaWWW). ViolaWWW is what most people equate with "Viola". It's a convenient association, but it is important to keep in mind that ViolaWWW (the Viola−based World Wide Web browser) is just an application, albeit...

This work treats species of the genus Microsternus Lewis, 1887 from Asia and North America. A new genus is described: Neosternus (type species Microsternus higonius Lewis, 1887). A new species is described: Microsternus pengzhongi. A new synonym is provided: Microsternus tricolor taiwanicus Nakane (=Microsternus tricolor Lewis). Three species previously placed in Microsternus Lewis, 1887 are tr...

Population trends represent a minimum amount of information required to assess the conservation status of a species. However, understanding and detecting trends can be complicated by variation among habitats and regions, and by dispersal connecting habitats through source-sink dynamics. We analyzed trends in breeding populations between habitats and regions to better understand the overall dyna...

We demonstrated a substrate-moving vapor-liquid-solid (VLS) route for growing composition gradient ZnCdSSe alloy nanowires. Relying on temperature-selected composition deposition along their lengths, single tricolor ZnCdSSe alloy nanowires with engineerable band gap covering the entire visible range were obtained. The photometric property of these tricolor nanowires, which was determined by blu...
