Artificial aquatic habitats are ubiquitous in anthropogenic landscapes and highly susceptible to colonization by invasive plant species. Recent research into the ecology of infectious diseases indicates that the establishment of invasive plant species can trigger ecological cascades which alter the transmission dynamics of vector-borne pathogens that imperil human health. Here, we examined whet...

Wetlands are one of the most important ecosystems on Earth. There is an urgent need to quantify the biophysical parameters (e.g., plant height, aboveground biomass) and map total remaining areas of wetlands in order to evaluate the ecological status of wetlands. In this study, Environmental Satellite/Advanced Synthetic Aperture Radar (ENVISAT/ASAR) dual-polarization C-band data acquired in 2005...

In recent decades the grass Phragmites australis has been aggressively invading coastal, tidal marshes of North America, and in many areas it is now considered a nuisance species. While P. australis has historically been restricted to the relatively benign upper border of brackish and salt marshes, it has been expanding seaward into more physiologically stressful regions. Here we test a leading...

Climate change will likely affect flooding regimes, which have a large influence on the functioning of freshwater riparian wetlands. Low water levels predicted for several fluvial systems make wetlands especially vulnerable to the spread of invaders, such as the common reed (Phragmites australis), one of the most invasive species in North America. We developed a model to map the distribution of...

Phragmites australis subsp. (hereon Phargmites), has become a dominating threat to the Great Lakes wetlands at time when climate change pressures are also compromising integrity of native habitat. Understanding role this invader plays in resiliency is crucial order improve management decisions protect and restore wetlands. This literature review was conducted predict if wetland’s effects could ...

این پژوهش به منظور تعیین ارزش غذایی، ترکیبات شیمیایی و گوارش پذیری علوفه نی رشد کرده در منابع مختلف آبی از جمله آب شیرین، آب شور و فاضلاب و اثر آنها بر کیفیت تغذیه ای علف نی انجام شد. پس از جمع آوری نمونه های گیاهی و تقسیم کردن هر کدام از نمونه های علوفه ای به 4 قسمت مختلف از نظر برگ و ساقه (20 سانتی متر پایین، 20 سانتی متر وسط، قسمت بالایی، و کل گیاه) و آسیاب آنها، ترکیبات شیمیایی آن ها از جمل...

PREMISE OF THE STUDY Intraspecific hybridization between native and introduced lineages of a species can increase invasiveness and may lead to the decline of native lineages. The introduction of Eurasian Phragmites australis has caused profound changes to wetland habitats across North America, yet evidence for hybridization between native and introduced Phragmites australis in North America is ...

We report the 3.16 Mb draft genome of Acinetobacter sp. strain BMW17, a Gram-negative bacterium in the class of Gammaproteobacteria, isolated from the rhizospheric region of Phragmites karka, an invasive weed in Chilika Lake, Odisha, India. The strain BMW17(T) is capable of degrading cellulose and is also an efficient plant growth promoter that can be useful for various phytoremedial and commer...

Estuarine sediments are the repository for a wide range of contaminants. Anthropogenic impacts and variations in the belowground biomass of salt marsh plants potentially select for different sediment microbial communities with different functional capabilities, including the ability to biotransform anthropogenic contaminants. There are large differences in both root morphology and the amount of...
