Soil disturbance has been widely recognized as an important factor influencing the structure and dynamics of plant communities. Although soil reworkers were shown to increase habitat complexity and raise the risk of plant invasion, their role in regulating the interactions between native and invasive species remains unclear. We proposed that crab activities, via improving soil nitrogen availabi...
Pomacea canaliculata (Ampullariidae) has extensively invaded most Asian constructed wetlands and its massive herbivory of macrophytes has become a major cause of ecosystem dysfunctioning of these restored habitats. We conducted non-choice laboratory feeding experiments of P. canaliculata using five common macrophyte species in constructed wetlands including Ipomoea aquatica, Commelina communis,...
Phragmites australis (an invasive plant in North America) was used as feedstock for ABE (acetone-butanol-ethanol) fermentation by Clostridium saccharobutylicum. Sulphuric acid pretreated phragmites hydrolysate (SAEH) without detoxification inhibited butanol production (0.73 g/L butanol from 30 g/L sugars). The treatment of SAEH with resin L-493 prior the fermentation resulted in no inhibitory e...
Novel species of microfungi described in the present study include the following from Australia: Diaporthe ceratozamiae on Ceratozamia robusta, Seiridium banksiae on Banksia marginata, Phyllosticta hymenocallidicola on Hymenocallis littoralis, Phlogicylindrium uniforme on Eucalyptus cypellocarpa, Exosporium livistonae on Livistona benthamii and Coleophoma eucalyptorum on Eucalyptus piperita. Se...
Chromium is a pollutant present in tannery wastewater, its removal is necessary for protection of the environment. Penisetum purpureum, Brancharia decumbens and Phragmites australis were grown hydroponically in experimental gravel beds to determine their potential for the phytoremediation of solutions containing 10 and 20 mg Cr dm. These concentrations, similar to tannery wastewater after initi...
27 r Ostendorp, W. and Möller, J., 1991. EM-algorithm as a tool for structure analysis of stands of the common reed (Phragmites australis). Ecol. Modelling, 53: 27-38. The frequency distributions of morphometric and mechanical properties of randomly sampled stalks of seven reed stands at Lake Constance-Untersee are analysed by the Estimation-Maximisation Algorithm. The aim was to look for compo...
A description is given of Pythium litorale sp. nov., a new species from reed stands in Germany. Pythium litorale was among the most abundant species when the oomycete community of littoral soils of Lake Constance was studied. It was consistently isolated from flooded as well as from drier reed sites. The species is characterized by subglobose, papillate and internally proliferating sporangia, g...
