Biological soil crusts (BSCs) can improve the stability and health of native plant communities in arid ecosystems. However, it is unknown whether BSCs can also inhibit invasions of exotic vascular plants on stabilized reclaimed sand dunes. To answer this question, we conducted a greenhouse experiment to test the effects of cyanobacteria-dominated BSCs on 1) seed germination and biomass of an ex...

Background: Many herbal medications have been used to treat various liver diseases. But the concerns of medicine induced injury also existed. In this respect, we would like report several cases with imporved elevated aminotransferase after treating including Artemisia capillaris. Case Reports: We four patients levels (ATLs), which indicate hepatocellular damages. After receiving medicines thera...

Previous work in New Zealand has shewn that genetic variation within populations of Agrostis capillaris can be comparable to that between populations, even between populations over a very wide environmental range. To determine whether this reflects the recent advent of A. capillaris in New Zealand, with a small founding gene pool and a short time for ecotypic differentiation, populations from a...

Recently, the requirements for quality and safety of poultry products have significantly increased, what has notably limited use antibiotics in feeding poultry. This is one reasons growing interest phytogenic feed additives. We conducted an experiment to determine influence Artemisia capillaris on young quail meat productivity. To carry out experiment, we formed five groups, each counting 100 h...
