-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...

A growing body of literature supports microbial symbiosis as a foundational principle for the competitive success of invasive plant species. Further exploration of the relationships between invasive species and their associated microbiomes, as well as the interactions with the microbiomes of native species, can lead to key new insights into invasive success and potentially new and effective con...

Spartina alterniflora Loisel. is one of the most invasive species in the world. However, little is known about the role of artificial mowing in its invasiveness and competiveness. In this work, we studied the effect of mowing on its interspecific interactions with native species Phragmites australis (Cav.) Trin ex Steud of the Yangtze Estuary, China. We calculated their relative neighbor effect...

Introduced Phragmites australis is rapidly spreading in North America, threatening wetland plant communities and endemic native genotypes (Phragmites australis americanus). Lack of successful long-term control resulted in initiation of biological control research. In the past, the program targeting introduced Phragmites has focused on several promising potential biological control agents with l...

Restoration of habitats impacted by invasive plants is becoming an increasingly important tool in the management of native biodiversity, though most studies do not go beyond monitoring the abundance of particular taxonomic groups, such as the return of native vegetation. Yet, the reestablishment of trophic interactions among organisms in restored habitats is equally important if we are to monit...

Phragmites australis (ssp australis) is an aggressive colony-forming species that displaces emergent vegetation in North America, including native bulrushes (Schoenoplectus sp.) and both invasive cattails (Typha sp.). expansion can alter habitat negatively affect reptiles, amphibians, birds; less known about Phragmites’ utility as fish its impact on communities freshwater coastal wetlands. To a...

Background and aims We review evidence for hybridization of Phragmites australis in North America and the implications for the persistence of native P. australis ssp. americanus populations in North America. We also highlight the need for an updated classification system, which takes P. australis intraspecific variation and hybridization into account. Methodology We reviewed available published...

قبیله های arundineae وdanthonieae جهت نگارش فلور ایران مورد مطالعه و بررسی قرار گرفت. در بررسی جنس phragmites مشخص شد که این جنس درایران دو گونه دارد. محدوده انتشار phragmites karka علاوه بر منطقه ای محدود از جنوب شرق ( دشت لوت- بلوچستان ) که اولین بار توسط لئونارد گزارش شده است، مناطقی از جنوب استان کرمان ( بم ) و شمال شرق ایران ( خراسان )را نیز شامل می شود. با توجه به محدود بودن دامنه انتشار ...

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 ...

Establishing relationships between biodiversity and ecosystem function is an ongoing endeavor in contemporary ecosystem and community ecology, with important practical implications for conservation and the maintenance of ecosystem services. Removal of invasive plant species to conserve native diversity is a common management objective in many ecosystems, including wetlands. However, substantial...
