-Phragmites austrailis have been commonly planted on sludge treatment wetlands due to its high resistance to sludge waste; thus sludge treatment wetlands are commonly referred to as “reed beds”. Phragmites’ aggressive nature and high productivity allow this invasive plant species to form monoculture stands, alter ecosystem processes, outcompete and replace native species. Thus, native alternati...

Data management today often consists of data placed into a spreadsheet, and may include plans to migrate the data to a relational database. We describe a more nuanced view of data management for a scientific field station that takes into account the diversity of elements that comprise an information system useful to scientists and to the public. By considering the many kinds of data processes a...

حفاظت از کیفیت منابع آبی موجود در مناطق خشک و نیمه خشک اهمیتی فراوان دارد. به همین دلیل استفاده از سامانه نیزارهای مصنوعی برای پالایش فاضلاب های شهری، صنعتی و کشاورزی توجه زیادی را در تمام نقاط جهان به خود جلب کرده است. این امر از غنیشدن منابع آبی به مواد غذایی بر اثر تخلیه مستقیم فاضلاب ها به این منابع جلوگیری می کند. با توجه به رشد گیاهان آبزی به صورت طبیعی در زهکش های روباز کشاورزی، هدف از ا...

PREMISE OF THE STUDY Invasive plants are a great threat to the conservation of natural ecosystems and biodiversity. Allelopathy as a mechanism for invasion of plants such as Phragmites australis, one of the most aggressive invaders, has the potential to suppress neighboring plant species. Allelopathic interference, through root exudates of P. australis on native Melaleuca ericifolia, was invest...

زنبور ساقه‌خوار نی، Tetramesa phragmitis (Erdös, 1952) برای اولین‌بار از ایران گزارش می‌شود. نمونه‌های این زنبور طی بررسی عوامل مهار زیستی گیاه نی،Phragmites australis (Cav.)(Poaceae)  در استان آذربایجان غربی از ارومیه جمع‌آوری و شناسایی شد. این گونه، در منطقۀ Trans- Palaearctic انتشار دارد.

Water is one of the most important elements involved in the creation and development of healthy life. Haphazard disposal of untreated wastewater from households as well as institutions and industry is causing severe deterioration of water bodies in many urban areas in the developing world. There are several methods to treat the municipal wastewater for intended use. One of the methods of the tr...

Harper (1977) has recently stressed the significance of the modular construction of plants. Plants respond to density not so much by changing the proportions of their parts, as by changing the number of basic modules of which they are composed. In the case of deciduous rhizomatous perennials, such as Typha orientalis, the basic module can be defined as a single above-ground shoot and its associ...

AIMS We use a regional comparison of Phragmites australis (common reed) subsp. americanus, P. australis subsp. berlandieri and introduced P. australis (possibly five sublineages) in the Chesapeake Bay, the St Lawrence River, Utah and the Gulf Coast to inform a North American perspective on P. australis invasion patterns, drivers, impacts and research needs. FINDINGS AND RESEARCH NEEDS: Our regi...

Abstract Purpose Paludiculture (crop cultivation in wet peatlands) can prevent carbon and nutrient losses while enabling biomass production. As vegetation rewetted peatlands is often nitrogen (N) limited, input of N-rich water may promote production removal. However, it unclear how N loading soil characteristics affect yield, dynamics, ecosystem service provisioning paludiculture. Methods We st...
