“…; ARTS and LEUVEN, 1988;ROELOFS, 1983). A similar shift in species composition of the vegetation was shown in experiments in which macrophytes were exposed to acid rain for a prolonged period of time (SCHUURKES et al, 1987;ROELOFS et al, 1984).…”

“…Although in The Netherlands acidification causes a general increase in ammonium concentrations (SCHUURKES et al, 1987;1988), actual concentrations are still very low compared to those causing toxic effects in other macrophytes, for example Ceratophy//um (BEST, 1980). The current model formulations were used with two important objectives in mind.…”

“…The lakes are isolated from groundwater and have no surface inflow or outflow, therefore acidification is caused by direct atmospheric deposition only. Besides sulphur deposition, ammonium deposition plays an important role (SCHUURKES, 1986;SCHUURKES et al, 1987), especially as the most sensitive lakes are situated in regions with the highest densities of ammonia emitting bioindustries (ERISMAN et aL, 1989;SCHUURKES etaL, 1988).…”

To predict changes in vegetation as a result of acidification in shallow Dutch lakes a mathematical model was formulated which describes the growth of Uttorella uniflora and Juncus bulbosus, species characteristic for non-acidified and acidified situations, respectively. The two species compete for light, C02 and nutrients. The model integrates current knowledge about the ecophysiology of the species. The results generated by the model are similair to field data concerning dominance of the species in different habitats. L. uniflora is able to grow well under environmental conditions associated with acidification, as long as it is not outcompeted by J. bulbosus. The competitive advantage of morphological adaptions of the macrophyte species are discussed in relation to the model results.

“…Acidification due to sulphuric acid, without nitrogen inputs, has not resulted in an increased mass growth of Juncus bulbosus and a diverse isoetid vegetation remains present. However, after increasing the nitrogen concentration in the precipitation (19 kg N ha -1 yr -1 or higher as ammonium sulphate; control <2 kg N ha -1 yr -1 ), similar changes in floristic composition as under field conditions have been observed: a dramatic increase in dominance of Juncus bulbosus, of submerged aquatic mosses and of Agrostis canina (Schuurkes et al, 1987). These results demonstrate that the observed changes occurred because of the effects of ammonium sulphate deposition, leading to both eutrophication and acidification.…”

“…the quantity of acid above which these types of waters may acidify within a short period, Schuurkes et al 1987;Van Dam & Buskens 1993), the total potential acid deposition has decreased by about 30% over the years 1980-1989, mainly due to decreased wet and dry SOx deposition (Erisman 1992). To assess how these types of ecosystems react to a decrease in atmospheric S-deposition, two moorland pools that differ in trophic status and morphometry were studied in detail.…”

Abstract. The chemical composition of surface waters of two Dutch moorland pools and of incident precipitation, was monitored from 1982 to 1990. For this period, sulfur and water budgets were calculated using a hydrochemical model developed for well-mixed nonstratifying lakes. Total atmospheric deposition of S decreased significantly after 1986 at both locations. A model describing the sulfur budget in terms of input, output and reduction/oxidation processes predicted a fast decrease of pool water SO-concentrations after a decrease of atmospheric input. However, SO-concentrations in the surface water was lowered only slightly or remained constant. Apparently a source within the lake caused the unexpectedly high SO4-concentrations. The possible supply of SO2-from the sediment through regulation by (K-)AI-SO4 containing minerals or desorption of SOd-from positively charged surfaces in the sediment was evaluated. Solubility calculations of pore water with respect to alunite, basaluminite and jurbanite indicated that SO2-concentration was not regulated by these minerals. It is suggested here (1) that desorption of SO 2-from peaty sediments may account for the estimated S04-supply provided that the adsorption complex is periodically recharged by partial oxidation of the upper bottom sediments and (2) that because of exposure of a part of the pool bottom to the atmosphere during dry summers and subsequent oxidation of reduced S, the amount of S4-may be provided which complements the decreasing depositional SO0-input. In future research these two mechanisms need to be investigated.
