Cyanobacteria colonizing the feather moss Pleurozium schreberi were isolated from moss samples collected in northern Sweden and subjected to physiological and molecular characterization. Morphological studies of isolated and moss-associated cyanobacteria were carried out by light microscopy. Molecular tools were used for cyanobacteria identification, and a reconstitution experiment of the assoc...

Sphagnum (spp.) is widely distributed in permafrost regions around the arctic and subarctic. The moisture content of the moss layer affects the thermal insulative capacity and preservation of permafrost. It also controls the growth and collapse history of palsas and other peat mounds, and is relevant, in general terms, to permafrost thaw (therrnokarst). In this study, we test and calibrate seve...

The moss Physcomitrella patens has become a powerful model system in modern plant biology. Highly standardized cell culture techniques, as well as the necessary tools for computational biology, functional genomics and proteomics have been established. Large EST collections are available and the complete moss genome will be released soon. A simple body plan and the small number of different cell...

This method is adapted from a protocol described by Grimsley et al. (1977). For more information about P. patens as a model organism, see The Moss Physcomitrella patens: A Novel Model System for Plant Development and Genomic Studies (Cove et al. 2009a). For details about the growth of P. patens on cellophane overlay plates, see Culturing the Moss Physcomitrella patens (Cove et al. 2009b). For p...

Moss (Bryum argenteum) continues to become one of the most problematic weeds in creeping bentgrass (Agrostis palustris) putting greens. Control of moss can be approached in many different ways, including chemical applications, and cultural practices such as correcting shading or poor drainage. A study was conducted at Springdale Country Club (Springdale, Ark.) to evaluate the effectiveness of s...

Uniflagellate zoosporic "fungi" (=Chytridiomycota and the zoosporic protista Hyphochytriomycota) are common inhabitants of soil. However, at what scale differences in their spatial distribution can be detected is poorly known. The first objective of this study was to assess the association of organismal distribution and frequency with two microhabitats: moss-covered and exposed forest soils, at...

Thirteen liverworts and the same number of mosses are reported from recent collections in New Caledonia some type specimens kept PC. Among them, 13 new to this French oversea territory (seven six mosses, including genus Rhaphidostichum M.Fleisch.). Ectropothecium papillosulum Thér. is a synonym E. sodale (Sull.) Mitt. Isopterygium sarasinii proposed as I. albescens (Hook.) A.Jaeger. Hymenostomu...
