Biology of the Gall Midge Spanolepis selloanae (Diptera, Cecidomyiidae), a Candidate Biological Control Agent of the Invasive Grass Cortaderia selloana

Entomologia Experimentalis et Applicata, EarlyView.
Spanolepis selloanae (Diptera, Cecidomyiidae) infests Cortaderia selloana (pampas grass). It lays eggs in the spikelets, where larvae feed on female parts. The high prevalence of the midge and its combined impact in seed production, condition and viability strongly reduces the reproductive output of C. selloana.

Antioxidant response to cadmium in Phragmites australis plants

Plant Physiology and Biochemistry, 2002
Phragmites ( Phragmites australis Ca. (Trin.) ex Steud) plants exposed to a high concentration of CdSO4 (50 ƒÝM) for 21 d were analysed with respect to the distribution of metal, its effects on antioxidants, the antioxidant enzymes and the redox status in leaves, roots and stolons. The highest accumulation of Cd2+ occourred in roots followed by leaves,

Vegetation types alter soil respiration and its temperature sensitivity at the field scale in an estuary wetland.

PLoS ONE, 2014
Vegetation type plays an important role in regulating the temporal and spatial variation of soil respiration. Therefore, vegetation patchiness may cause high uncertainties in the estimates of soil respiration for scaling field measurements to ecosystem ...

Dietary selectivity mediates niche overlap and interspecific competition in a reedbed warbler community in southern Europe

Ibis, EarlyView.
Sympatric species are expected to use resources differently along one or more ecological dimensions. This can be complex when there is partial separation along multiple dimensions, such as where bird species exhibit similarities in habitat use and diet.

The biodegradation of organic chemical waste using a constructed horizontal reedbed treatment system [PDF]

, 2007
The aim of the project was to evaluate the potential for a constructed reedbed (planted with Phragmites australis) to aid in the biodegradation of triethylene glycol (TEG) under normal climatic conditions experienced at the site.

Fragmented grasslands in different landscape structures provide different opportunities for cavity‐nesting Hymenoptera

Insect Conservation and Diversity, EarlyView.
Grassland fragmentation effects on cavity‐nesting Hymenoptera are habitat‐specific. Isolated sand steppe fragments are associated with higher brood‐cell abundance. In loess steppes, higher flower frequency increases bee brood‐cell production and parasitoid activity. Abstract The global decline in insects threatens ecosystem functioning, but the drivers

Response Patterns of Soil Organic Carbon Fractions and Storage to Vegetation Types in the Yellow River Wetland

Land
To promote soil carbon (C) sequestration and alleviate climate change, it is crucial to understand how vegetation types affect soil organic C (SOC) storage and stability in riverine wetlands.

Assessing the Impact of Hydraulic Retention Time and Sawdust on the Elimination of Pb and Co from Oily Wastewater via Vertical-Flow Constructed Wetlands (VFCWs) with Phragmites Australis Cultivation [PDF]

Iranian Journal of Chemical Engineering
Constructed wetlands have been increasingly used as an effective method for removing heavy metals from wastewater. This study aimed to investigate the combined effect of sawdust and Hydraulic Retention Time (HRT) on the performance of vertical-flow ...
