introduction and aims: acinetobacter baumannii in recent decay has become an increasing concern in hospitals for its ability to acquire antibiotic resistance determinants rapidly and becoming resistant to almost all of the antibiotic classes. borage (echium amoenum  fisch. et mey), is a wild annual plant of boraginaceae family, grows in northern mountains of iran and has largely been used by ir...

there are many remediating methods for the polluted soils but only phytoremediation is a cost effective, environmental friendly, aesthetically pleasing approach that is most suitable for many countries. the purpose of this study was to investigate the potential of native plants for phytoremediation of contaminated soils with lead, zinc, cadmium and nickel in the rangelands around national lead ...

The presence of non-native plants on dumps in Kuzbass was studied. 26 included the Black Book Flora Siberia were identified: Acer negundo, Amoria hybrida, Atriplex sagittata, Conium maculatum, Conyza canadensis, Echinochloa crusgalli, Echinocystis lobata, Echium vulgare, Elaeagnus angustifolia, Epilobium adenocaulon, Hordeum jubatum, Impatiens glandulifera, Lactuca serriola, Lepidium densifloru...

Background and objectives: Plants play a significant role in the prevention and treatment of diseases and can even prevent and reduce the adverse effects of conventional treatments.  Echium amoenum Fisch is one of the most commonly used medicinal plants, and has long been used as a traditional herbal medicine for many diseases in Iran. Gas chromatography-mass spectrome...

Ultraviolet-B (UV-B) radiation is a key but under-researched environmental factor that initiates diverse responses in plants, potentially affecting their distribution. To date, only a few macroecological studies have examined adaptations of plant species to different levels of UV-B. Here, we combined herbarium specimens of Hieracium pilosella L. and Echium vulgare L. with a novel UV-B dataset t...

An analytical model consisting of adult plants and two types of seeds (unripe and mature) is considered and successfully tested using experimental data available for some invasive weeds (Echium plantagineum, Cytisus scoparius, Carduus nutans andCarduus acanthoides) from their native and exotic ranges. The model accounts for probability distribution functions (pdfs) for times of germination, gro...
