Role of earthworms against metal contamination: a review
Heavy metal contamination, occurring due to both natural and anthropogenic activities, is a subject of major concern throughout the globe. Increase in heavy metal content can have an adverse impact on functioning of the soil ecosystem by hampering the activities of soil fauna. Earthworms play an important role in metal pollution monitoring and are widely […]
Characterization of β-tubulin cDNA(s) from Catharanthus roseus
Vinblastine and vincristine are anti-tumor drugs produced by different species of Vinca. Vinca alkaloids depolymerize microtubules and as a result interfere with the normal formation of microtubules during cell division. Extremely low amount of vinca alkaloids in Vinca species and increased demand for chemotherapy are motives to scale up its production by biotechnological approaches. Here, […]
Quantification of betulinic, oleanolic and ursolic acid as medicinally important triterpenoids in wild and in vitro callus culture of Salvia sahendica (Lamiaceae): a comparative study
In the present study, quantitative determination of betulinic acid (BA), oleanolic acid (OA) and ursolic acid (UA) as well-known medicinal pentacyclic triterpenoids was simultaneously carried out in wild and in vitro callus culture of Salvia sahendica Boiss. Buhse (Lamiaceae) by reverse-phase high performance liquid chromatography (HPLC). The plant is an endemic medicinal species which is […]
On the annually recurrent of green macroalgal bloom phenomenon in Timsah Lake, Suez Canal, Egypt
Consequence macroalgae blooms phenomenon annually in Timsah Lake, the green macroalgal blooms phenomenon was increased in spring 2014 than the previous study in spring 2004 spring 2005 in order to cover large parts of El Taawen area at the south of Timsah Lake. Macroalgal species were growing firstly on the lakebed in the late winter […]
The effect of environmental pollutions on phytochemical parameters and antioxidant activity of Quince, Apple, and Mulberry fruits
Human actions are causing the slow killing of plant and animal species in nature through toxic pollution due to industrial and technological advancement in recent decades. To reveal metal toxicity, the effects of industrial pollution on phytochemical parameters of Malus domestica, Cydonia oblonga and Morus alba were determined. So, plants were collected from east of […]
Assessment of socio-economic factors and plant agrobiodiversity (Case study: Kashan city, Iran)
Conservation of agrobiodiversity is essential to achieve sustainable agricultural systems. A study was conducted in Kashan city in Iran in 2013 to assess the effects of socio-economic factors on agrobiodiversity Six villages were chosen so that they provided a uniform distribution over the region. Data were gathered using semi-structured questionnaires and explored using stepwise linear […]
Mortality of red mullet Mullus barbatus barbatus (Linnaeus., 1758) in Western Algerian coasts
Red mullet Mullus barbatus barbatus (Linnaeus, 1758) is a demersal species. It is an important commercial fish in Mediterranean coasts of Algeria, as a target of trawl fishery. Annual landings of this species are approximately 17.3% of the total landings of demersal fishes species (DPRH, 2010). Of a total of 1679 specimens, 1150 females and […]
Assessment of the environmental condition of mountainous streams in macrohabitat scale (Case Study: Delichai Stream in Tehran, Iran)
In the present research environmental condition of a mountainous stream in macro habitat scale is investigated, and Delichai mountainous stream is selected as the pattern stream for investigation. At first hydrological and hydraulic approaches in the study stream were investigated. In the next step, physical habitat in macro scale was evaluated. Based on the results […]
Diversity and distribution of butterflies in the open and close canopy forests of Cadaclan, San Fernando La union botanical garden of North Luzon, the Philippines
Butterflies were sampled in Cadaclan, San Fernando La Union Botanical Garden (LUBG) of North Luzon to provide information on species-level diversity trend and distribution of butterflies on the open and close canopy portion of the dipterocarp forest from 2012-2014 using field transect method Species accumulation curve shows that additional sampling is needed for the possible […]
Importance of protected areas for biodiversity conservation in south Côte d’Ivoire: case of National Floristic Center of F.H.B University of Abidjan
To show the impact of human activity on biodiversity in humid equatorial region, termites, insects recognized as bio-indicators of climate change in the tropics were studied in two habitats: The National Center for Floristic (CNF), a preserved habitat for 51 years and the Campus of Cocody (CC), a strongly anthropic environment. Termites were sampled using […]
