1 Determining the mechanisms by which invasive species exclude natives is critical for conserving and restoring native populations in impacted habitats. In recent decades the grass Phragmites australis has been aggressively invading coastal marshes of North America, with monocultures often replacing diverse assemblages of plants. 2 Our objective was to quantify how P. australis modifies the abi...
The invasive species Spartina alterniora Loisel was introduced to the eastern coast of China in the 1970s and 1980s for the purposes of land reclamation and the prevention of soil erosion. The resulting interspecific competition had an important influence on the distribution of native vegetation, which makes studying the patterns and mechanisms of the interactions between Spartina alterniora Lo...
During the investigation of lignicolous freshwater fungi in plateau lakes Yunnan Province, China, eight Lentitheciaceae species were collected from five viz. Luguhu, Qiluhu, Xingyunhu, Cibihu, and Xihu lake. Based on morphological characters phylogenetic analysis combined ITS, LSU, SSU, tef 1-α sequence data, a new genus Paralentithecium, two (Paralentithecium suae, Setoseptoria suae), three re...
We investigated biodegradation of technical nonylphenol (tNP) in Phragmites australis rhizosphere sediment by conducting degradation experiments using sediments spiked with tNP. Accelerated tNP removal was observed in P. australis rhizosphere sediment, whereas tNP persisted in unvegetated sediment without plants and in autoclaved sediment with sterile plants, suggesting that the accelerated tNP...
Phragmites australis is a cosmopolitan grass and often the dominant species in the ecosystems it inhabits. Due to high intraspecific diversity and phenotypic plasticity, P. australis has an extensive ecological amplitude and a great capacity to acclimate to adverse environmental conditions; it can therefore offer valuable insights into plant responses to global change. Here we review the ecolog...
The pyrolytic kinetics of Phragmites australis was investigated using thermogravimetric analysis (TGA) method with linear temperature programming process under an inert atmosphere. Kinetic expressions for the degradation rate in devolatilization and combustion steps have been obtained for P. australis with Dollimore method. The values of apparent activation energy, the most probable mechanism f...
Hamond C., Martins G., Loureiro A.P., Bremont S., Medeiros M.A., Bourhy P. & Lilenbaum W. 2015. First isolation and characterization of Leptospira interrogans serogroup Australis from swine in Brazil. Pesquisa Veterinária Brasileira 35(1):6-8. Laboratório de Bacteriologia Veterinária, Instituto Biomédico, Universidade Federal Fluminense, Rua Hernani de Melo 101, Niteroi, RJ 24210-030, Brazil. E...
The one-seeded, serrate leaf margined junipers of Southwestern United States and northern Mexico consist of J. angosturana, J. californica, J. coahuilensis var. arizonica, J. c. var. coahuilensis, J. monosperma, J. pinchotii, J. occidentalis var. australis, J. o. var. occidentalis and J. osteosperma. Recent nrDNA and trnC-trnD sequence data were compared with RAPDs analysis and two of the taxa ...
