Bryophytes and nutrient cycling
D. H. Brown,Jeffrey W. Bates +1 more
TL;DR: A summary is given of recent laboratory work on the internal redistribution of elements in Rhytidiadelphus squarrosus and of field experiments involving fertilizer addition to Pseudoscleropodium purum; their significance is assessed.
Journal ArticleDOI
Desiccation effects and cation distribution in bryophytes
D. H. Brown,G. W. Buck +1 more
TL;DR: In this paper, the cations in a range of bryophytes, using a differential ion displacement technique, have been analyzed, and it has shown that potassium is mainly soluble within the cells, calcium is bound, exchangeably, to sites in the cell wall and is insoluble within the cell and magnesium is present in all three locations.
Journal ArticleDOI
Mineral Cycling and Lichens: The Physiological Basis
D. H. Brown,Rosalie M. Brown +1 more
TL;DR: A modified sequential elution procedure is proposed that enables quantification of insoluble paniculate mineral matter in addition to soluble elements in intercellular, extracellular-exchangeable and intracellular sites.
Journal ArticleDOI
Uptake and Effect of Cations on Lichen Metabolism
D. H. Brown,Richard P. Beckett +1 more
TL;DR: In this article, heavy metal uptake by lichens is briefly reviewed in terms of the trapping of paniculate material and the uptake of soluble cations, and the effects of competing cations and the energetics of the processes considered.
Journal ArticleDOI
Ionic control of intracellular and extracellular Cd uptake by the moss Rhytidiadelphus squarrosus (Hedw.) Warnst.
J. M. Wells,D. H. Brown +1 more
TL;DR: Low competition from ions removed by KNO3 pretreatment resulted in a higher affinity of both transport sites and extracellular exchange sites for Cd, Ca and Mg.
