Mycorrhizal fungi in arid and semiarid rangelands have received little study in southwest Asia and north Africa, although they are important in food production and rangeland productivity. The desert truffles of the genera Terfezia and Tirmania form fruiting-bodies and mycorrhizae with rangeland plants. This thesis treats the taxonomy and the...
A gas chromatographic procedure was developed for the determination
of nanogram quantities of hydrocyanic acid using a
flame ionization detector. Excellent chromatograms were obtained
on a porous polyaromatic polymer column (Porapak Q) at 60°C. The
procedure was employed for the analysis of HCN in aqueous cyanide
solutions. Solutions as low...
Discussions around adapting water management systems to climate change often express the need to increase the flexibility and adaptive capacity of current systems, and to implement robust strategies going forth. While these topics lie at the center of many climate change discussions, transforming adaptation recommendations into tangible tools and information...
