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.
Here, we present the whole-genome sequence of Photobacterium halotolerans strain, MELD1, isolated from the roots of a terrestrial plant Phragmites australis grown in soil heavily contaminated with mercury and dioxin. The genome provides further insight into the adaptation of bacteria to the toxic environment from where it was isolated.
A new mite species Allochaetophora iranica sp. nov. (Tetranychoidea: Allochaetophoridae), is described and illustrated based on females and deutonymphs collected from Phragmites australis (Poaceae) in Iran (Kerman Province). This is the third report of the family Allochaetophoridae for the world and first report of it from Asia.
in last decades, oil spill pollution has become an important issue of concern due to its serious environmental impacts; therefore, necessary actions should be taken to prevent or reduce these types of pollution and their environmental consequences. natural organic sorbents are emerging as proper choices for oil spill cleanup due to their availability, eco-friendliness, and low cost. in this stu...
The common reed, Phragmites australis, is a highly aggressive species that outcompetes native species on shorelines, wetlands and roadways across the Great Lakes Basin. Prior to my analysis glyphosate and imazapyr (Habitat 7) herbicides were applied to more than 600 acres at selected sites along the west shore of lower Green Bay. I explored alternative secondary control treatments for increasin...
