The presence of sulfated polysaccharides in cell walls of seaweeds is considered to be a consequence of the physiological adaptation to the high salinity of the marine environment. Recently, it was found that sulfated polysaccharides were present in certain freshwater Cladophora species and some vascular plants. Cladophora (Ulvophyceae, Chlorophyta) is one of the largest genera of green algae t...

We present proteome data from the microbiota (feces) after a diet shift from a natural diverse to a monocultural meadow with Dactylis glomerata. The abundant grasshopper species, Chorthippus dorsatus, was taken from the wild and kept in captivity and were fed with Dactylis glomerata for five days. For phytophagous insects, the efficiency of utilization of hemicellulose and cellulose depends on ...

Herbal medicine is an ancient practice that has been gaining acceptance of the medical class through scientific studies that prove its effectiveness. However, its use should still be cautious. Medicinal plants have potential toxic effects not yet discovered, and may have unproven interactions with other medications. The use of drugs during pregnancy is still very dangerous and vigorously studie...

The paper discusses various aspects of biosorption of microelements by marine seaweeds to be used as mineral feed supplement for livestock. n the study, biosorptive properties of a single marine species Cladophora rupestris and mixed species of algae from the Baltic Sea (a mixture f Cladophora sp. and Enteromorpha prolifera) were investigated. The mechanism of biosorption was identified as cati...

Morphological studies and phylogenetic analysis based on the ITS sequence data showed that there is considerable differences within the Puccinia striiformis complex on members of Triticeae(Triticum and Hordeum), Dactylis glomerata and Poa pratensis. Based on the above molecular and morphological data, we suggest dividing P. striiformis as follows: - P. striiformis s. str. mainly on Triticeae. -...

Survival of incipient non-indigenous populations is dramatically altered by early predation on new colonisers. These effects can be influenced by morphological traits, such as coloniser size and density. The Australian non-native Pacific Oyster Crassostrea gigas is generally more fecund and faster growing compared to the native Saccostrea glomerata found in the same habitat. It is therefore imp...

The effect of protection from sheep grazing on indigenous plant species in relatively mesic, strongly modified Poa cita grassland, was examined using paired grazed and ungrazed sites. Ungrazed sites, fenced at times ranging from four to more than 24 years ago, had fewer species, lower indigenous cover and lower tussock density than adjacent grazed sites. The dominance of adventive species, part...

The objective of this study was to determine whether seasonal deferred grazing regimes could be used to increase the composition of cocksfoot (Dactylis glomerata L) in perennial pastures growing in temperate Australia. The experiment was conducted over three years at two sites; one in Victoria and the other in Tasmania, Australia. Relative to the control of continuous grazing, deferred grazing ...

BACKGROUND Oysters have important ecological functions in their natural environment, acting as global carbon sinks and improving water quality by removing excess nutrients from the water column. During their life-time oysters are exposed to a variety of pathogens that can cause severe mortality in a range of oyster species. Environmental stressors encountered in their habitat can increase the s...
