Abstract Asteraceae, the daisy family, are one of most diverse families angiosperms and predominant in many ecosystems, including grasslands, deserts, savannas high-elevation mountains. They characterized by a peculiar inflorescence, capitulum, which mimics flower, but is actually made up tightly grouped florets. The capitulum considered key character underpinning impressive evolutionary succes...

The process of oviposition in A. walkerae was observed and found to be a sequence of exactly coordinated, interlocking events independent of the age of ticks. Egg-laying always commenced with numerous dorso-ventral movements of the capitulum. The pedipalps were spread during the last dorso-ventral movement and lowered to the ventral body wall embracing the genital aperture on both sides. Simult...

Milk thistle is an important medicinal crop. In this two-year field study, the optimal form [bulk (non-structured), nanoparticles (NPs)] and concentration (0, 50, 100 mg L?1) of chitosan titanium dioxide (TiO2) applications for improving seed yield, as well mineral (N, Mg, Fe, Ti), protein, oil contents were investigated in five ecotypes. Leaf gas exchange, ratio variable to maximum fluorescenc...

A new pedunculate barnacle, Probathylepas faxian gen. and sp. nov., is described from a hydrothermal vent in the Okinawa Trough. A new scalpelliform family, Probathylepadidae, is also proposed for the new genus and species. Probathylepadidae differs from all other five families of the order Scalpelliformes by the capitulum bearing eight primal plates and two whorls of imbricating supplementary ...
