this study was carried out as a factorial experiment with 5 levels of cadmium (cd) (o, 25, 50, 75, and 100 mg/kg), 5 levels of salinity (control, 4, 5, 6, and 7 ds/m), and two soil textures (sandy loam and clay loam). the results showed that the amount of cd in root and shoot of sunflower increased as soil salinity and cd concentration increased. the best concentrations for cd phytoremediation ...

Salinity has plagued irrigated agriculture throughout history (Tanji, 1990), and soil salinization is an old–yet– new problem in arid regions. For example, there are approximately 100 million ha of salt–affected soils in China, accounting for one tenth of the total land area (Li, 2009). The development of effective salinity control practices requires an understanding of the causal relationship ...

A growing body of research on plant-microbe interactions in soil is contributing to the development of a new, microbially based perspective on plant community ecology. Soil-dwelling microorganisms are diverse, and interactions with plants vary with respect to specificity, environmental heterogeneity, and fitness impact. Two microbial processes that may exert key influences on plant community st...

In mountain pastures worldwide, studies investigating vegetation changes due to long-term grazing and environmental are sparse, especially regarding the effects of in snowmelt patterns. The outstanding availability historical data from Kyrgyz creates unique opportunities study past forecast future changes, making them ideal model ecosystems. Using a resurvey approach, we explored response manag...

Background & Aim: Milk thistle [Silybum marianum (L.) Gaertn] is an annual or biennial plant, native to the Mediterranean area, which has spread in north and south of Iran. A fruit of milk thistle contains a relatively high amount (approx. 20%) of oil, which exhibits wound-healing, anti-burn, and hepatoprotective properties. Experimental: In this research, a pot experiment wa...

The rapid decline in the extent and health of coastal salt marshes has created a need for nondestructive methods for evaluating the condition of salt marsh ecosystems. This paper describes simultaneous uses of field sampling and remote sensing approaches to understand salt marsh ecosystem functions and species distributions and discusses the implications for salt marsh monitoring using remote s...

Plant diversity drives changes in the soil microbial community which may result in alterations in ecosystem functions. However, the governing factors between the composition of soil microbial communities and plant diversity are not well understood. We investigated the impact of plant diversity (plant species richness and functional group richness) and plant functional group identity on soil mic...
