Influence of Quercus robur Throughfall on Elemental Composition of Pleurozium schreberi (Brid.) Mitt. and Hypnum cupressiforme Hedw
نویسندگان
چکیده
The aim of this paper was to estimate the influence of deposition of N, Mg, P, S, K, Ca, Mn, Fe, Co, Ni, Cu, Zn Cd, and Pb from under canopy in comparison with open space waters on the elemental composition of the moss layer to test the hypothesis that Pleurozium schreberi (Brid.) Mitt. and Hypnum cupressiforme Hedw. growing under the influence of canopy throughfall of Quercus robur contain higher amounts of elements than the same species growing in an open area. P. schreberi and H. cupressiforme growing under a Q. robur canopy contained higher amounts of N, Mg, P, S, K, Ca, Mn, Ni, Cu, Pb, and H. cupressiforme (in addition also Zn) than the same species growing in an open area. Principal component and classification analysis (PCCA) ordination revealed that P. schreberi and H. cupressiforme growing under throughfall and in open spaces were distinguished by a factor of 1 related to Mg, P, S, Mn, Fe, Zn, Pb (positive scores), and K, Ca (negative scores) and both species were distinguished by a factor of 2 related to Co, Cu, and Cd (negative scores).

Short-Term Responses in Maximum Quantum Yield of PSII (Fv/Fm) to ex situ Temperature Treatment of Populations of Bryophytes Originating from Different Sites in Hokkaido, Northern Japan
There is limited knowledge available on the thermal acclimation processes for bryophytes, especially when considering variation between populations or sites. This study investigated whether short-term ex situ thermal acclimation of different populations showed patterns of site dependency and whether the maximum quantum yield of PSII (Fv/Fm) could be used as an indicator of adaptation or tempera...
متن کاملDrought changes nutrient sources, content and stoichiometry in the bryophyte Hypnum cupressiforme Hedw. growing in a Mediterranean forest
We conducted a 6 year field experiment in an evergreen Quercus ilex forest where we simulated the increased drought projected by Global Circulation Models (GCM) and ecophysiological models for the immediate decades. We tested the hypothesis that enhanced drought will change C, N, P, K, Ca, Fe, Mg, Mo and S concentrations of the widespread moss Hypnum cupressiforme Hedw. and its capacity to abso...
متن کاملHigh diversity of fungi associated with living parts of boreal forest bryophytes
Bryophytes are a dominant and functionally important component of the forest floor vegetation in boreal forests, yet little is known about the fungal diversity associated with these abundant plants. Using molecular identification, we document an ecologically and phylogenetically diverse array of fungi associated with the living parts of three widespread and abundant boreal forest bryophytes, i....
متن کاملDoes heavy metal deposition affect nutrient uptake by moss Pleurozium schreberi?
Heavy metals may influence chemical composition of plants, and thus shape elemental stoichiometry of plant communities. That is because some physiological processes aiming at neutralization of contaminant toxicity require increased acquisition of some nutrients (e.g. N, S, P or Ca). The aim of the study was to evaluate the heavy metal deposition in Poland using moss Pleurozium schreberi as a bi...
متن کاملBiomonitoring of metal deposition by using moss transplant method through Hypnum cupressiforme (Hedw.) in Mussoorie.
Metals Cu, Zn, Cd and Pb were surveyed at 14 sampling sites by using moss Hypnum cupressiforme through active monitoring technique. Samples were transplanted in all four directions of Mussoorie city and were harvested after exposure of four months (representing each season) to analyze metal precipitation and its trend at different sites during 2005. Bioaccumulation ability for metals was evalua...
