در طی نمونهبرداریهای انجامشده از دشمنان طبیعی شتهها در اصفهان در سال 1385، لاروهای مگس شکارگر از خانوادهی Chamaemyiidae در حال تغذیه از شتهی Hyalopterus pruni (Geoffroy) روی گیاه نی Phragmites sp. جمعآوری شد و پس از پرورش آنها در آزمایشگاه، حشرات کامل توسط دکتر Gaimari در آمریکا با نامLeucopis argentata Heeger شناسایی شد. طبق اطلاعات موجود، این گونه تخصص میزبانی روی شتهی H. pruni، و صر...
Date in this paper highlights the applications of constructed horizontal surface flow (HF-CW) wetland with two different local plants (Louis latifoila and Phragmites -australis (Cav.) Trin) at the wastewater treatment plant in Babol city. This system was designed as an advanced treatment unit in field scale after the treatment plant. Parameters such as Total Dissolved Solid (TDS), Total Suspend...
The amount of oxygen released by Phragmites roots and the community structure and in situ activity of nitrifying bacteria in the root biofilms were analyzed by the combined use of 16S rRNA gene-cloning analysis, quantitative PCR (qPCR) assay and microelectrodes. Axial and radial O₂ microprofiles were obtained for individual roots of Phragmites in a horizontal flow reactor fed with artificial me...
we studied cu concentration on part of aras riparian vegetation. cu was selected as an index metal due to polluting the aras river through agarak copper mines drainage. results of cu concentration in indicator plant have been examined using spss16. considering the situation of the copper mines as well as the habitat of the indicator plant, two stations before and after the exit of the industria...
Temporal variations in methane emissions from emergent aquatic macrophytes in two boreonemoral lakes
Methane (CH4) emissions via emergent aquatic macrophytes can contribute substantially to the global CH4 balance. We addressed temporal variability in CH4 flux by using the static chamber approach to quantify fluxes from plots dominated by two species considered to differ in flux transport mechanisms (Phragmites australis, Carex rostrata). Temporal variability in daily mean emissions from early ...
چکیده فلزات سنگین از عوامل مهم آلایندة محیط زیستی به شمار می روند که از طریق مناطق ساحلی و رودخانه ها وارد دریا و از طریق زنجیرة غذایی در بدن آبزیان تجمع می یابند. گیاهان آبزی به عنوان حلقه ای از زنجیره غذایی به واسطة جذب فلزات سنگین می توانند نشانگر افزایش نسبی غلظت این عناصر در آب یا رسوبات اکوسیستم های موردنظر باشند. در این تحقیق به منظور تعیین میزان غلظت فلزات سرب، روی، مس و کادمیم و نقش...
Invasive plants often successfully occupy large areas encompassing broad environmental gradients in their invaded range, yet how invader dominance and effects on ecological communities vary across the landscape has rarely been explored. Furthermore, while impacts of invasion plant are well studied, it is not understood whether responses above-ground (plant) below-ground (microbial) coupled. Her...
The stable isotope signatures of marine transient and resident nekton were used to investigate trophic linkages between primary producers, marsh macrophytes, phytoplankton, benthic microalgae, and consumers within the Delaware Bay. A whole estuary approach was used to compare the flux of nutrients from primary producers to juvenile weakfish (Cynoscion regalis), bay anchovy (Anchoa mitchilli), a...
This study was to compare the total phenolic (TP) content in extracts from eleven plant materials collected at different geographical locations in Kenya, Nigeria, and USA. These plants have been selected because the majority of them are highly pigmented, from yellow to purple, and would therefore have economic value in industries for producing antioxidants and surfactants. Two of them were coll...
Herbaspirillum sp. strain GW103 was isolated from rhizosphere soil of the reed Phragmites australis on reclaimed land. Here we report the 5.05-Mb draft genome sequence of the strain, providing bioinformation about the agronomic benefits of this strain, such as multiple traits relevant to plant root colonization and plant growth promotion.
