“…This finding contradicts both our hypothesis and a major assumption behind the utilization of meshbags to assay EMF growth; that EMF will be selected for in low organic carbon substrates. It is possible that the granite catchment with its very low belowground carbon allocation due to magnesium deficiency, and the serpentinite catchment, with the unique chemistry of a serpentine soil (Krám et al ., ), in conjunction with the high historic acid deposition levels this area sustained during the second half of the 20 th century, have combined to make these study sites anomalous in their relative EMF : saprotrophic fungal compositions. It is also important to note, that read abundance of a particular taxa, or group of taxa, may not accurately reflect active fungal biomass (Amend et al ., ), and thus the fraction of sequence reads from EMF should probably be at best taken as an approximation for the proportion of fungal hyphal ingrowth of mycorrhizal origin.…”

SummaryWe investigated fungal growth and community composition in buried meshbags, amended with apatite, biotite or hornblende, in Norway spruce (Picea abies) forests of varying nutrient status. Norway spruce needles and soil collected from forests overlying serpentinite had low levels of potassium and phosphorus, those from granite had low levels of magnesium, whereas those from amphibolite had comparably high levels of these nutrients.We assayed the fungal colonization of meshbags by measuring ergosterol content and fungal community with 454 sequencing of the internal transcribed spacer region. In addition, we measured fine root density.Fungal biomass was increased by apatite amendment across all plots and particularly on the K-and P-deficient serpentinite plots, whereas hornblende and biotite had no effect on fungal biomass on any plots. Fungal community (total fungal and ectomycorrhizal) composition was affected strongly by sampling location and soil depth, whereas mineral amendments had no effect on community composition. Fine root biomass was significantly correlated with fungal biomass.Ectomycorrhizal communities may respond to increased host-tree phosphorus demand by increased colonization of phosphorus-containing minerals, but this does not appear to translate to a shift in ectomycorrhizal community composition. This growth response to nutrient demand does not appear to exist for potassium or magnesium limitation.

“…Sklářský potok -Jizerka is intensively monitored within the Mountain Waters project of the Earthwatch Institute. Lysina and Pluhův Bor (Krám et al 1997(Krám et al , 2009Hruška & Krám 2003;Shanley et al 2004) are in the Czech GEOMON network of small forested catchments and in the International Long-Term Ecological Research network. Moreover, Lysina is in two international networks of the International Cooperative Programme -ICP Integrated Monitoring and ICP Waters, both organized under the Economic Commission for Europe of the United Nations.…”

A synoptic study of acidified mountain streams covering six Czech sites was performed. The aim was to provide biological data from small mountain streams in catchments with historically high acid atmospheric deposition, which have so far been subject of intensive long-term monitoring of hydrology and hydrochemistry only, in order to follow the development of the structure of benthic macroinvertebrates in the course of recovery from acidification. We focused on small headwater streams with minimum human influence in the catchment and relatively low concentrations of dissolved organic matter. The sites were classified according to their water pH status: three of them were strongly acidified (pH 4.07-4.57, concentration of reactive aluminium R-Al 448-1913 µg L −1 ), two were moderately acidified (pH 5.08-6.38, R-Al 52-261 µg L −1 ) and one non-acidified (pH 7.63-7.89, R-Al 12-59 µg L −1 ). The largest biotic difference detected by PCA was in the presence of the caddisflies Drusus, Rhyacophila, and Chaetopteryx villosa and stoneflies Leuctra pseudocingulata and Diura bicaudata. The results indicate that at the most acidified sites (the Lysina and the right branch of the Litavka), the process of biological recovery has not started yet due to an insufficient increase in stream pH. Indeed, MAGIC modelling published earlier shows that significant increases cannot be expected in the following decades. An average pH of at least 4.5 is needed for return of less acid-tolerant taxa such as Diura bicaudata, Leuctra major, L. pseudocingulata, L. pseudosignifera, Drusus or Rhyacophila. However, at the Sklářský potok -Jizerka site, both the clear-cut of mature spruce plantations in [1984][1985][1986][1987][1988][1989][1990] and the regional drop in SO2 emissions in the 1990s resulted in a decline of acid deposition and rising streamwater pH. Mean annual pH at the Sklářský potok -Jizerka outlet increased from 4.0 (1982-1985) to 5.3 (1990-1994), but episodic acidification has still resulted in a delay in recovery of the biota, particularly acid-sensitive species, which may be expected within a couple decades.

Aluminum (Al) chemistry was studied in soils and waters of two catchments covered by spruce (Picea abies) monocultures in the Czech Republic that represent geochemical endmembers of terrestrial and aquatic sensitivity to acidic deposition. The acid-sensitive Lysina catchment, underlain by granite, was compared to the acid-resistant Pluhův Bor catchment on serpentine. Organically-bound Al was the largest pool of reactive soil Al at both sites. Very
