continuous and excessive use of organophosphorus compounds has led to thecontamination of water and soil ecosystems. the degradation of organophosphorusinsecticides, chlorpyrifos, chlorpyrifos- methyl, cyanophos and malathion in mineral saltsmedia were studied. the effect of additional biofertilizers, singly or combined withorganic amendments, on chlorpyrifos and cyanophos degrading activity in...

The deterioration of alpine grassland has great impact on ecosystem services in the alpine region of Qinghai-Tibetan Plateau. However, the effect of grassland degradation on ecosystem services and the consequence of grassland deterioration on economic loss still remains a mystery. So, in this study, we assessed four types of ecosystem services following the Millennium Ecosystem Assessment class...

Rangeland degradation is one of the global concerns affecting the pastoralists and those who suffer from its negative environmental consequences. Grazing exclosure has been extensively used among the techniques implemented by the government to protect the fertility of threatened rangelands. The impact of exclosure has been a controversial issue; therefore, it is important to understand its effe...

with regard to the mutual relations between plant and soil as the main component of rangeland ecosystems, this research has been identified the indicator species in environmental conditions of dry regions as the most important tools in ecological management of these ecosystems. therefore the steppe and dry rangelands of kooh - e- namak in qom province was selected. sampling was done by plot in ...

Chronic wasting disease (CWD) and sheep scrapie can be transmitted via indirect environmental routes, and it is known that soil can serve as a reservoir of prion infectivity. Given the strong interaction between the prion protein (PrP) and soil, we hypothesized that binding to soil enhances prion resistance to enzymatic digestion, thereby facilitating prion longevity in the environment and prov...

The progressive development of civilization and intensive industrialization has contributed to the global pollution of the natural environment by heavy metals, especially the soil. Degraded soils generally contain less organic matter, and thus, their homeostasis is more often disturbed, which in turn manifests in changes in biological and physicochemical properties of the soil. Therefore, new p...

Long-term ecological data play a vital role in ecological conservation and restoration, however, using information from local forest soil pollen data to assist restoration remains a challenge. This study analyzed two data sets, including 1) surface soil pollen (0-5 cm) and current vegetation data from four near-natural communities and four plantations, and 2) fossil pollen from soil profiles (0...

Passage of agricultural runoff through vegetated drainage ditches has been shown to reduce the amount of pesticides, such as atrazine, exiting out of agricultural watersheds. Previous studies have found that microbial communities in soil from fields treated with atrazine display enhanced rates of atrazine degradation. However, no studies have examined the potential for atrazine degradation in d...
