Effect of bioaugmentation of crude oil polluted tropical soils on the growth of Panicum maximum
The effect of bioaugmentation of crude oil polluted soils on the growth of Panicum maximum was examined in a green house study. Weathered polluted soil samples (2% w/w) in experimental pots were planted and inoculated with hydrocarbon utilizing bacterial species (Micrococcus sp. RZ1, Pseudomonas sp. RZIII, Bacillus sp. RZIII, and Bacillus sp. GSIII). Samples of […]
A study on the biodiversity of snake island in South Andaman
Snake Island is an uninhabited small rocky islet off Carbyn’s Cove in Port Blair, Andaman. The biodiversity of this rocky island is its distinctive feature as it becomes a small habitat for various organisms close to the open sea. During this present study a total no. of 217 species were recorded out of which 205 […]
Suitability of Eucalyptus camaldulensis dehnh. growing in kurdistan region of iraq for sawn lumber industry
The absence of utilization-plan for the plantations of eucalypt in Kurdistan region created the necessity of exploring the wood and its validity for sawn lumber production. Twenty two trees of Eucalyptus camaldulensis Dehnh. were cut, bucked, and sawed for boards with different thicknesses. Boards were dried once in summer; second in winter under three methods […]
Diversity and agronomic impact of rice stem borer at Nkolbisson, Yaoundé-Cameroon (Central Africa)
Today, rice has become one of the most consumed cereals in Africa in general and Cameroon in particular. The low domestic production imposes a strong import that accentuates the country’s trade imbalance. To reduce this issue of external dependency, the national government is encouraging domestic production. However, producer’s efforts are inhibited by various constraints among […]
A comparative study of phenolic, anthocyanin, flavonoid compounds and antioxidant properties of medicinal fruit of Vaccinium arctostaphylos L. (case study: three regions of Talesh, Iran)
Plants are rich sources of phenolic compounds (flavonoids, tannins and anthocyanins) that are considered as the most important natural antioxidants. Vaccinium arctostaphylos is a shrub that belongs to Ericaceae family and has long been used in Iran traditional medicine due to its effects such as reducing blood glucose and pressure. The main metabolites of V. […]
Effect of crude oil pollution on the rhizosphere microbial communities of Mangifera indica L and Elaeis guineensis Jacq in Rivers State, Nigeria
This study investigated the effect of crude oil pollution and remediation on the fungi and bacteria communities of M. indica and E. guineensis rhizospheres using three sites – Unpolluted Site (UPS), Polluted and Treated Site (PTS), and Polluted and Untreated Site (PUS). Population of fungi in both M. indica and E. guineensis rhizospheres was highest […]
Biodiversity of cultivated Trigonella foenum-graecum L. in Tunisia, North Africa
In agricultural systems, biodiversity includes diversity within species and among species and provides many benefits for production, resilience and conservation. This article aims to study the diversity of Trigonella foenum-graecum L., an annual herb of Leguminosae with a worldwide distributed culture, among thirty eight local populations collected from different Tunisian regions. The variability analysis was […]
Lipid peroxidation, oxidative stress and respiratory metabolism alteration in the freshwater ciliate Paramecium tetraurelia exposed to cypermethrin, a pyrethroid insecticide
Oxidative damage by increased production of reactive oxygen species have been involved in the toxicity of several pesticides. Thus, the aim of this study was to investigate the effect of cypermethrin, a widely used type II pyrethroid, on the oxidative stress biomarkers and the respiratory metabolism of Paramecium tetraurelia. Different concentrations of the insecticide (0.05, […]
Diversity of vegetation around the springs to support water resource conservation in belu, East Nusa Tenggara, Indonesia
The research was conducted in catchment area of Lahurus, Wetihu, Wewai and Mauhalek, Lasiolat District of Belu Regency, East Nusa Tenggara. The purpose of this research was to find out species composition and stratification of vegetation in springs to support water resource conservation. Vegetation sampling was conducted using quadrate method. Data were collected for further […]
Comparative influences of manures and NPK fertilizer on growth performance, root yield and reserpine content of Rauvolfia spp
The study revealed the growth performance, root yield and reserpine content in the root part of R. serpentina and R. tetraphylla under four different treatment regimes (T1,T2, T3, T4). Three types of cutting like root, root-stem junction and stem of 2 to 2.5 years old plants of both the species were used. It was concluded […]
