Carbon istotope ratios of modern, 10,000-year-old, and more than 40,000-year-old Atriplex confertifolia (C(4)) material from Nevada caves indicate that the C(4) photosynthetic pathway was operating in these plants over that period. Samples of a plant with crassulacean acid metabolism, Opuntia polyacantha, were also measured, and a shift in the 8(13)C value from -21.9 per mil (more than 40,000 y...

The present study aimed to investigate the possibility of using hyperspectral imaging data identify invasive and weed species in agrocenoses ecosystem. most common weeds grain agrocenoses, i.e., Ambrosia artemisiifolia L., Euphorbia seguieriana Neck., Atriplex tatarica Glycyrrhiza glabra Setaria pumila (Poir.) Roem. Schult, served as objects. population weeds, especially is for selected region ...

Vacuoles were isolated via protoplasts from the leaves of a halophyte Atriplex gmelini C.A.Mey., grown in culture solution supplemented with 250 millimolar NaCl. Lysis of the protoplasts was induced by lowering the medium osmolarity (1.2 to 1.0 molar sorbitol) and adding a detergent, a synthesized cholate derivative, 3-([3-cholamidopropyl] dimethylammonio)-1-propanesulfonate at a concentration ...

it has often been stated or implied that grazing is an important factor in the land degradation process, a suggestion supported by various research projects, and this study investigated the effect of livestock grazing on stem height, crowncover, production, basal diameter, stem biomass, litter, leaf-stem index (leaf to stem weight) , root diameter and weight and seed production per individual o...
