“…The relationship between DFS deep % (sourced from valley-side through-flow) and FPOM might be explained by transport of particulate matter within subsurface environments (McDowell-Boyer et al, 1986). Through-flow may entrain organic matter from perched wetlands and deeper soils of the valley sides, which is discharged at points of upwelling groundwater (Boissier and Fontvieille, 1995). Organic matter is an important energy source (Buffam et al, 2001), and during periods of low resource availability macroinvertebrates may aggregate upon isolated patches of high organic matter concentration (Tiegs et al, 2008) such as those provided by DFS deep .…”

“…Higher streamflow and temperature variability results in reduced macroinvertebrate community persistence (Townsend et al, 1987) and macroinvertebrate diversity (Death and Winterbourn, 1995); the degree of flow regime attenuation might therefore influence macroinvertebrate community composition. Furthermore, groundwater may be influential through the distribution of organic matter, which can be entrained by through-flow and discharged into surface waters (Boissier and Fontvieille, 1995). Organic matter is an important energy source for macroinvertebrates, which may aggregate upon patches of the resource in otherwise resource-depleted environments (Tiegs et al, 2008).…”

“…It is mostly the input of nutrients from the interstitial habitats to the river that have been investigated, such as nitrate (Triska etal., 1989 ;Valett, 1993), phosphorous (Valett et al, 1990), silica (Hendricks & White, 1991), and dissolved organic carbon (Wallis et al ., 1981, Crocker & Meyer, 1987) . In contrast, the inputs of bacteria from interstitial habitats or from terrestrial ecosystems through soil leachates to rivers were still little studied (Leffe et al, 1993 ;Boissier & Fontvieille, 1995) . Most of these studies used indirect estimations of the fluxes : the link between hydrologic events and bacterial densities in the river (Mc Dowell, 1984 ;Baker & Farr, 1977), comparisons between channel productivity and standing stocks in the water column (Edwards et al, 1990), or comparisons between upstream and downstream bacterial densities (Wainright et al, 1992) .…”

Comparison of solutes, nutrients, and bacteria inputs from two types of groundwater to the Rh�ne river during an artificial drought

et al. 1996

Solute, nutrient and bacterial inputs to the River Rhone from the interstitial habitat of a gravel bar and the floodplain aquifer were investigated during an artificial drought . Eight springs were investigated : four groundwater-fed springs in the floodplain, located at the bottom of the bank ; and four interstitial-fed springs located at the downstream end of a gravel bar. During this period, the inflows of groundwater to the river represented an average input of 0 .77 mg 1-1 of nitrogen (of which 93 .3% were nitrates), 0 .0187 mg 1-1 of total phosphorus (of which 42 .2% was orthophosphate), 3 .56 mg 1 -' of silica, 2 .315 ± 0 .703 mg 1 -1 of dissolved organic carbon (DOC, of which 47% was biodegradable) and 7 .3 x 104 ± 3 .7 x 10 4 bacteria per ml (of which 8 .8% were active) . Silica, DOC, biodegradable DOC, and bacteria concentrations displayed temporal variations during the study, which seem to be linked to the biological activity of the groundwater biofilm. There was a strong heterogeneity between the two types of groundwater that flow to the river : concentrations of calcium and alkalinity were higher in bank springs than in gravel bars springs . In these latters, sulfate, sodium, nitrogen, phosphorus were significantly higher .

“…The production and leaching of DOC is affected by biological factors (McDowell and Likens, 1988;Boissier and Fontvieille, 1995;Christ and David, 1996;Brookes et al, 1999) and by chemical factors, such as pH (or liming) (Andersson and Nilsson, 2001;Filep et al, 2003). However, when compared to anthropogenic disturbances in forest soils (e.g., clear-cutting, land clearing, fire), much less attention has been focused on the effects of natural disturbances on soil properties.…”

To understand changes in soil nutrients in Pinus massoniana forests affected by pine wilt disease (PWD), we examined the seasonal variation in dissolved organic carbon (DOC), dissolved organic nitrogen (DON) and soil nutrients in Hefei, East China. The results showed a considerable decline in the population density and basal area in both highly disturbed (HD) and moderately disturbed (MD) forest stands and an increase in dead pine trees, causing pronounced changes in the stand structure and soil nutrient status. The concentrations of DOC and NO 3 --N were significantly (p < 0.05) higher in every season in the disturbed forests compared to the undisturbed (UD) forest stand. However, during spring and summer, the variation in the DON and NH 4 + -N values was significantly (p < 0.05) lower in the HD forest stand than in the UD stand; total N concentrations were higher in the disturbed forests in every season. During spring and autumn, the variation in total P values was significantly (p < 0.05) lower in the MD forest stand than in the UD stand, whereas the total P values were significantly (p < 0.05) lower in every season in the HD stand than in the UD stand. In this study, disturbance resulted in a considerable increase in DOC, N and NO 3 --N when compared to the UD stand and a pronounced increase in soil nitrate in the HD stand, which may lead to soil acidification, thereby increasing the possibility of soil nutrient leaching.
