The biodiversity of arbuscular mycorrhizal fungi (AMF) was surveyed in the Kolm region of Iran in three adjacent sites, a natural stand, a 10-year-old and a 15-year-old plantation of Amygdalus scoparia. To date, there have been few studies of AMF biodiversity in Iran, especially in the western forests of the country. For this study, soil and root samples were taken from A. scoparia rhizosphere soil in spring and autumn. Almost half of the root length was colonized by AMF. We identified 13 AMF species belonging to Glomeraceae, Claroideoglomeraceae or Diversisporaceae. The three plantations differed in terms of soil electrical conductivity, organic C and P. Spore density was significant correlated with P concentration. Root length colonization was correlated only with soil Ca. Species diversity and richness were significantly correlated with soil N, P, organic C and spore density. AMF diversity in 15-year-old plantations was more similar to that in the natural stand than in the 10-year-old plantation. We confirmed that a 15-year-old plantation is not similar in terms of AMF colonization to natural stands. We conclude that more than 15 years are required for AMF colonization of plantations to resemble that of natural stands. © 2017 Northeast Forestry University and Springer-Verlag Berlin Heidelberg

Prosopis juliflora is one of the suitable tree species used as vegetation cover for sand dunes fixation. The objectives of this study were to determine the effect of P. juliflora afforestation and its canopy coverage classes on soil carbon (C) stock and nutrient status in sand dunes after 22 years since afforestation. We hypothesized that increasing the canopy coverage would result in higher soil C stocks and nutrient content. We selected two 10-ha afforested sand dunes with 25-50% and more than 75% canopy coverage, respectively, and a 10-ha non-afforested dune (control). At each site, 15 soil samples were taken at two depths (0-5 cm and 5-50 cm). The results indicated a strong increase in the topsoil C stock (from 0.54 to 4.49 tC ha-1 in control and afforested sites, respectively), while a lower change in subsoil C stock was detected (3.0 and 4.6 tC ha-1 in control and afforested sites, respectively). Although, different canopy classes resulted in no significant differences in soil C stock, significant differences were observed for all the soil physico-chemical properties that were studied. © SISEF.

Background and aim – Arbuscular mycorrhizal fungi (AMF) communities are a main component of soil. They could be an indicator of fertility of semi-arid ecosystems. We aimed to analyse the biodiversity of AMF and understorey plants in Zagros forest (Iran), and to find their relationships with environmental conditions (physiography and soil). Methods – Seventy-five plots (20 m × 20 m) were randomly divided from 1 700 to 1 900 m a.s.l. In each plot, four 1.5 m × 1.5 m microplots were established and all trees, shrubs, and herbaceous species coverage were recorded. Furthermore, four soil samples were taken from a depth of 0–20 cm in each microplot (one pooled sample for each main plot) by auger in spring. These soil samples were used for AMF assessment and soil physiochemical properties. Results – Seventeen AMF species (in Glomeraceae, Claroideoglomeraceae, Diversisporaceae, Gigasporaceae, and Acaulosporaceae) and 47 plant taxa (in Poaceae, Asteraceae, Fabaceae and fourteen other families) were identified. Tests determined that the factors soil P, slope, tree coverage, litter thickness, and soil texture affect AMF and plant communities. Soil physiochemical properties have an effect on AMF, plant diversity, and evenness diversity indices. Furthermore, there is a high correlation between plants and AMF diversity indices and any change in the plant diversity will result in AMF changes. The results also showed positive correlations between plant diversity and AMF diversity. Conclusions – AMF and plant diversity indices are highly correlated, but this correlation could be affected by soil physiochemical properties and environmental factors. Moreover, canopy coverage and litter thickness are considered as strongly influencing both plants and AMF. © 2017 Botanic Garden Meise and Royal Botanical Society of Belgium. All rights reserved.

This work investigated the effect of using Kenaf bast fibre kraft pulps compared to Scotch Pine kraft pulps for producing microfibrillated cellulose (MFC) and its employment for improving mechanical and physical properties of handsheets made from unbleached kraft hardwood pulp. It was shown that MFC based on Kenaf fibres can be produced at higher consistencies [>5 % (w/w)] compared to when Scotch Pine is employed [≈2 % (w/w)] as raw material. The possibility of using a higher consistency when processing Kenaf is beneficial for the processing in microfluidizers. The rheological properties of the products were shown to be consistent with what is known for MFC-based systems. The studies indicate that the mechanical properties of handsheets from unbleached kraft hardwood pulp can be improved by replacing part of the unbleached kraft hardwood pulp fibres with either unbleached kraft Kenaf pulp or unbleached Scotch Pine kraft pulp. However, the same levels of improvements were obtained when using only a small amount [≈6 % (w/w)] of MFC based on Kenaf or Scotch Pine, when introduced into the system either as a dry strength additive or by coating pre-made handsheets. Finally, it was shown that the incorporation of MFC in handsheets decreases the air-permeability; this effect became amplified when the MFC was applied as a coating onto the handsheets. © 2013 Springer Science+Business Media Dordrecht.

Feeding deltamethrin-contaminated grains to domestic poultry, such as quails may result in toxic effects in these birds. This study was done to investigate the effects of recommended doses of deltamethrin, sometimes used in grain storage silos, on Japanese quail (Coturnix japonica). Quails were fed grains contaminated with 0.25 and 0.50 mg deltamethrin per kg diet for 21 days and the effects on survival and blood biochemical parameters were studied. Plasma uric acid, creatinine levels, and creatinine phosphokinase activity in the blood were increased. Aspartate aminotransferase and lactate dehydrogenase activities and glucose levels significantly increased in birds treated with the high dose of deltamethrin. Alanine aminotransferase activity and albumin or cholesterol levels were not changed, and acetylcholinesterase and alkaline phosphatase activities, total protein and globulin in plasma were decreased. Administration of 0.25 mg/kg deltamethrin caused increased blood triglyceride levels, 0.50 mg/kg deltamethrin decreased triglyceride levels. © 2015 Taylor & Francis.

A simple and sensitive sensor based on carbon paste electrode (CPE) modified by chitosan-coated magnetic nanoparticle (CMNP) was developed for the electrochemical determination of morphine (MO). The proposed sensor was characterized with scanning electron microscopy (SEM) and electrochemical impedance spectroscopy (EIS). The electrooxidation of MO was studied on modified carbon paste electrode using cyclic voltammetry, chronoamperometry and differential pulse voltammetry as diagnostic techniques. The oxidation peak potential of morphine on the CMNP/CPE appeared at 380 mV which was accompanied with smaller overpotential and increase in oxidation peak current compared to that obtained on the bare carbon paste electrode (CPE). Under optimum conditions the sensor provides two linear DPV responses in the range of 10-2000 nM and 2-720 M for MO with a detection limit of 3 nM. The proposed sensor was successfully applied for monitoring of MO in serum and urine samples and satisfactory results were obtained.
