the deleterious effects of salinity on plant growth and development are associated with the imbalance ion in plant, decreased k+ and increased na+, and ultimately yield loss. in order to evaluate the effects of salinity, 41 bread wheat varieties (trticum aestivum l.) were planted in the randomized complete block design with three replications under two saline irrigation conditions, 0.631 and 11...

Land use intensification is associated with loss of biodiversity and altered ecosystem functioning. Until now most studies on the relationship between biodiversity and ecosystem functioning focused on random loss of species, while loss of rare species that usually are the first to disappear received less attention. Here we test if the effect of rare microbial species loss on plant productivity ...

PURPOSE To estimate the annual loss of productivity from blindness and moderate to severe visual impairment (MSVI) using simple models (analogous to how a rapid assessment model relates to a comprehensive model) based on minimum wage (MW) and gross national income (GNI) per capita (US$, 2011). METHODS Cost of blindness (COB) was calculated for the age group ≥50 years in nine sample countries ...
