Duplicate samples of the two terrestrial moss species Hylocomium splendens and Pleurozium schreberi, which are widely used to monitor airborne heavy metal pollution, have been collected from eight catchments spread over a 1,500,000 km2 area in northern Europe. These were analysed for a total of 38 elements by inductively coupled plasma-mass spectrometry, inductively coupled plasma-atomic emissi...

The complete chloroplast DNA sequence (122 890 bp) of the moss Physcomitrella patens has been determined. The genome contains 83 protein, 31 tRNA and four rRNA genes, and a pseudogene. Four protein genes (rpoA, cysA, cysT and ccsA) found in the liverwort Marchantia polymorpha and the hornwort Anthoceros formosae are absent from P.patens. The overall structure of P.patens chloroplast DNA (cpDNA)...

Context. Studying the problem of active region heating requires precise measurements of physical plasma parameters such as electron density, temperature etc. It is also important to understand the relationship of coronal structures with the magnetic field. The Extreme-ultraviolet Imaging Spectrometer (EIS) aboard Hinode provides a rare opportunity to derive electron density simultaneously at di...

Water vapour and CO2 exchange were measured in moss-dominated vegetation using a gas analyser and a 0.3 x 0.3 m chamber at 17 sites near Abisko, Northern Sweden and 21 sites near Longyearbyen, Svalbard, to quantify the contribution of mosses to ecosystem level fluxes. With the help of a simple light-response model, we showed that the moss contribution to ecosystem carbon uptake varied between 1...

Biotim and Biomath recently started an ambitious R&D program aiming at the development of a new modelling and simulation tool, MoSS-CC (Model-based Simulation System for Cost Calculation), that supports a holistic economic evaluation of a WWTP over its life cycle. The use of dynamic simulation and the integration of variable operating costs in the assessment of scenarios will maximise the optim...

Biological soil crusts play important ecological functions in arid and semi-arid regions, while different crust successional patterns appeared in different regions. Therefore in this study, the environmental conditions between Shapotou (with cyanobacterial, lichen and moss crusts) and Dalate Banner (with only cyanobacterial and moss crusts) regions of China were compared to investigate why lich...

Genetic defects in complement regulatory proteins can lead to severe renal diseases, including atypical hemolytic uremic syndrome and C3 glomerulopathies, and age-related macular degeneration. The majority of the mutations found in patients with these diseases affect the glycoprotein complement factor H, the main regulator of the alternative pathway of complement activation. Therapeutic options...
