Bryophyte floras typically exhibit extremely low levels of endemism. The interpretation, that this might reflect taxonomic shortcomings, is tested here for the Macaronesian flora, using the moss species complex of Rhynchostegium riparioides as a model. The deep polyphyly of R. riparioides across its distribution range reveals active differentiation that better corresponds to geographic than mor...

Introduction: During the past two decades, the attention has been paid to the role of biological crusts in dry and semi-arid ecosystems. According to the roles of soil surface crusts in improving physical and chemical characteristics, and lack of sufficient information on their inherent characteristics, this research can be useful in understanding the mechanism of these crusts.   Materials an...

change system to measure the net exchange of CO2 at the surfaces of three shady feather moss and three exposed sphagnum moss sites in a black spruce forest during 35 days at the end of the 1995 growing season. Midday gross photosynthesis was 0.5 to 1.0 μmol m s by feather moss and 0.5 to 2.5 μmol m s by sphagnum moss. Photosynthesis by sphagnum moss was reduced by approximately 70% at 0 °C, and...
