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 […]

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, […]
