Rhizosphere is a micro zone with profoundly different microbiological and chemical properties compared to the bulk soil, where availability and fractionation of zinc (Zn) may also vary from the bulk soil. This greenhouse research was performed to study the available Zn and its fractions in the bean rhizosphere and bulk soils of 10 calcareous soils using rhizobox. Total organic carbon (TOC), dis...

Phosphorus behavior in waterlogged soils is significantly different from non-waterlogged soils. Changes in available phosphorus and inorganic phosphorus fractions after waterlogging in the paddy soils of north of Iran were studied in a laboratory research. A factorial experiment in a completely randomized design with two replications was performed with factors of soil at 14 levels (10 alkaline-...

In laboratory experiments, variously colored strains of animals, including those with albino phenotypes, are commonly used. The melanocortin theory suggests, however, that coloration phenotypes alter animal physiology and behavior. Animals the phenotype show photoreceptor degradation associated lowered visual accuracy, escape reactions, etc., presumably accompanied by prevailing nocturnal activ...

Humic substances are highly abundant organic compounds formed in soils and sediments by the decay of dead plants, microbes and animals. This book focuses on the important binding properties of these compounds that regulate the chemical reactivity and bioavailability of hydrogen andmetal ions in the natural environment. Topics covered include the physico-chemical properties of humic matter and i...

Microbes live just about everywhere on Earth—on and inside animals, plants, in soils, water. They also thrive underground environments. Caves mines are ecosystems often visited by humans. Many interesting microbes have evolved to survive these harsh where there not many nutrients available. To compete with other for nutrients, some produce antibiotics, which substances that can kill certain typ...

The sensitivity of terrestrial isopods to changes in both temperature and moisture make them suitable models for examining possible responses of arthropod macro-decomposers to predicted climate change. Effects of changes in both temperature and relative humidity on aggregation, growth and survivorship of species of isopods contrasting in their morphological and physiological adaptations to mois...

effects of different soil moisture regimes and p application on available and inorganic p forms were studied in four paddy soils, north of iran. a factorial experiment in a completely randomized design with two replications was performed in a laboratory study. factors of soil at four levels (two acid and two alkaline-calcareous soils), soil moisture contents at three different levels (air-dry, ...

Soil erodibility in arid regions, particularly in less developed soils, greatly depends on parent material. The objectives of this study included comparison of the potential of runoff and sediment production in soils with different parent materials and identification of the highly sensitive parent materials in Golabad watershed, 60 km northeast of Isfahan, with about 160 mm of annual precipitat...

We show examples of knots with the same polynomial invariants and hyperbolic volumes, with variously coinciding 2-cable polynomials and colored Jones polynomials, which are not mutants. AMS Classifications: 57M25, 57N70
