Wood distillate (WD) is an environmentally safe bio-based product stimulating plant growth and yield allowed in Italy organic farming. To the best of our knowledge, there are no studies on effects WD spontaneous plants growing among crops, including their functional traits such as biomass. test effects, we carried out a lab experiment artificially reconstructed arable communities composed five ...

Hexane, chloroform, ethyl acetate and ethanolic extracts of the aerial parts of Centaurea austro-anatolica Hub.-Mor. (Asteraceae) were evaluated against microorganisms, including multiresistant bacteria, using a paper disc diffusion method. The chloroform extract exhibited significant antibacterial activity toward all bacteria tested. The chemical composition of the chloroform extract was deter...

Malacitanolide (2), a new eudesmanolide isolated from the aerial parts of Centaurea malacitana, was characterized spectroscopically. The synthesis of 2 from cnicin (1), via the epoxide 3, confirmed the structure and stereochemistry of malacitanolide, as well as its biogenetic relationship with 1. Cytotoxic activity values for 2 are significantly higher than for 1.

To what extent can the mammalian visual system be shaped by visual behavior? Here we analyze the shape of the visual fields, the densities and distribution of cells in the retinal ganglion-cell layer and the organization of the visual projections in two species of facultative non-strictly subterranean rodents, Spalacopus cyanus and Ctenomys talarum, aiming to compare these traits with those of ...

Achene morphology of 49 taxa of the genus Centaurea L. was studied in terms of 19 different characteristics. On the basis of the variation in these features, some sections, such as sect. Cyanus with hairy hilum, were separated. Despite various differences, C. leuzeoides and C. gilanica were categorized in the section Psephelloideae, a section with lots of character variations within its species...

Wildflowers attract wildlife, increase pollinator habitat, and enhance the aesthetic value of landscape. Wildflower establishment is increasingly part an effort to reduce maintained turfgrass on golf courses, lawns, other environments. Weed competition decreases wildflower results in poor long-term stands. Research was conducted a controlled environment investigate tolerance species common post...
