The widespread use and consumption of crude oil draws the public's attention to the fate of petroleum hydrocarbons in the environment, as they can permeate the soil environment in an uncontrollable manner. Contamination of soils with petroleum products, including diesel oil (DO), can cause changes in the microbiological soil properties. The effect of diesel oil on the functional diversity of fu...

UNLABELLED Denitrifying fungi produce nitrous oxide (N2O), a potent greenhouse gas, as they generally lack the ability to convert N2O to dinitrogen. Contrary to the case for bacterial denitrifiers, the prevalence and diversity of denitrifying fungi found in the environment are not well characterized. In this study, denitrifying fungi were isolated from various soil ecosystems, and novel PCR pri...

Mycorrhiza is a mutualistic association between zone surrounding the root [2]. Although a lack in growth fungi and higher plants [1]. Different types of mycorrhizae response to VA-fungi inoculation in unsterilized soil was occur, distinguished by their morphology and to a also recorded, this result has been attributed to the fact certain extent, in their physiology. These include the that nativ...

The effect of arbuscular mycorrhizal (AM) fungus on growth and photosynthetic pigments in medicinally important Coriandrum sativum with different levels of Cadmium (Cd) was investigated. Plants inoculated with and without AM fungi were grown in soil with 0, 50 and 100 Cd mg kg soil. The plants 1 inoculated with AM fungi showed better growth and less toxic symptoms. Photosynthetic pigments were ...

The anecic earthworm Lumbricus terrestris L. was kept in laboratory microcosms containing beech forest soil without litter, with beech leaf litter or with lime leaf litter. The structure of microfungal communities in soil, litter and fresh and aged (100 days) earthworm faeces was analysed using the washing and plating technique. The passage of mineral soil through the gut of L. terrestris affec...

Progress in understanding changes in soil biology in response to latitude, elevation and disturbance gradients has generally lagged behind studies of above-ground plants and animals owing to methodological constraints and high diversity and complexity of interactions in below-ground food webs. New methods have opened research opportunities in below-ground systems, leading to a rapid increase in...

introduction: soil contaminations with heavy metals represent a potential risk to the biosphere and leads to increased concentration in ground and surface water. therefore metals mobility in soil has been extensively studied in the last decades. use of agrochemicals such as synthetic fertilizers and pesticides has resulted in soil and water pollution, and loss of biodiversity. cadmium is a heav...

Insect-pathogenic fungi are important natural enemies of insect pests but their dynamics in the soils of different agroecosystems are incompletely understood. In the present study, the seasonal occurrence and species diversity of insect-associated fungi in soil were investigated by baiting soil samples with larvae of Galleria mellonella. The survey included insect-pathogenic fungi, opportunisti...

The last several decades have seen dramatic increases in ungulate populations worldwide, and whitetailed deer in the eastern United States currently exist at unprecedented densities in many areas. Numerous studies have demonstrated the effects of high densities of white-tailed deer on forest communities. However, few studies have simultaneously examined the effects of deer on multiple component...
