Procedures for asymbiotic germination and seedling development under in vitro ex conditions were investigated Bletilla striata. Five different media (½ P6668 ¬Phytamax Orchid Maintenance Media, ½ Media with coconut water, P723 PhytoTechnology Seed Sowing MS media) culture sphagnum moss examined their effectiveness 8 weeks on seed of B. Germination occurred all media, however, the best rate was ...

Heavy metal escapement associated with ore trucks is known to occur along the DeLong Mountain Regional Transportation System (DMTS) haul road corridor in Cape Krusenstern National Monument, northwest Alaska. Heavy metal concentrations in Hylocomium splendens moss (n = 226) were used in geostatistical models to predict the extent and pattern of atmospheric deposition of Cd and Pb on Monument lan...

Distribution, mobility and toxicity of metals in natural waters are strongly related to their aqueous speciation. To understand the behaviour of an aqueous element and the transformation between chemical species, there is a need for reliable methods that enable measurements of specifi c fractions of metals. Ultrafi ltration has frequently been used to study speciation of metals in natural water...

Domain-Specific hypothesis, they seem at least as problematic for this theory as do many of the facts raised by Caramazza and Mahon for alternative accounts. However, the model is so underspecified that it is possible to develop explanations for most patterns of data. This flexibility significantly undermines the explanatory power of the account and essentially renders it unfalsifiable. The cha...
