Fungi and bacteria are key agents in plant litter decomposition freshwater ecosystems. However, the specific roles of these two groups their interactions during process unclear. We compared growth patterns degradative enzymes expressed by communities fungi grown separately coexistence on Phragmites leaves. The displayed both synergistic antagonistic interactions. Bacteria grew better together with than alone. In addition, there was a negative effect fungi, which appeared to be caused...
Abstract A wide range of human pharmaceuticals are present at low concentrations in freshwater systems, particularly sections polluted river. These compounds show high biological activity, often associated with a stability. characteristics imply potential impact these substances on aquatic biota even when environmental concentrations. Low flow conditions Mediterranean rivers, most which through densely populated areas and subjected to intensive water use, increase the risk emergent...
Intermittent rivers and ephemeral streams (IRES) encompass fluvial ecosystems that eventually stop flowing run dry at some point in space time. During the phase, channels of IRES consist mainly riverbeds (DRBs), prevalent yet widely unexplored ecotones between wet phases can strongly influence biogeochemistry networks. DRBs are often overlooked because they do not strictly belong to either domain soil or freshwater science. Due this dual character DRBs, we suggest concepts knowledge from...
We examined the effects of riparian vegetation removal on algal dynamics and stream nutrient retention efficiency by comparing NH4-N PO4-P uptake lengths from a logged an unlogged reach in Riera Major, forested Mediterranean northeastern Spain. From June to September 1995, we executed 6 short-term additions N (as NH4Cl) P Na2HPO4) 200-m section measure lengths. The study site included 2 clearly differentiated reaches terms canopy cover trees: first 100 m were completely (i.e., reach)...
River biofilms that grow on wet benthic surface are mainly composed of bacteria, algae, cyanobacteria and protozoa embedded in a polysaccharide matrix. The effects increased river water temperature biofilm formation were investigated. A laboratory experiment was designed employing two temperatures (11.1–13.2°C, night–day; 14.7–16.0°C, night–day) nutrient levels (0.054 mg P l−1, 0.75 N l−1; 0.54 7.5 l−1). Biofilm at the higher faster, while biomass mature determined by availability. specific...
Bacteria are highly diverse and drive a bulk of ecosystem processes. Analysis relationships between diversity single specific processes neglects the possibility that different species perform multiple functions at same time. The degradation dissolved organic carbon (DOC) followed by respiration is key bacterial function modulated availability DOC capability to produce extracellular enzymes. In freshwater ecosystems, biofilms metabolic hotspots major sites degradation. We manipulated biofilm...
Abstract Heterotrophic bacteria play a key role in the degradation of organic matter and carbon cycling river sediments. These bacterial communities are directly influenced by environmental variables that differ spatially temporally rivers. Here, we studied longitudinal patterns sediment community composition dissolved utilization under base flow drought conditions Mediterranean river. Our results indicated microbial were affected quality origin along continuum. In headwaters potential...
The microbial benthic community living in streams has a key role organic-matter processing. respective of epilithic biofilms (growing on rocks) and epipsammic surficial sandy substrata) the degradation organic matter was evaluated Mediterranean stream (Riera Major, northeastern Spain). Along with structural variables (algal chlorophyll a, bacterial density), we measured extracellular enzymatic activities (β-glucosidase, β-xylosidase, phosphatase), photosynthetic activity (H14CO3−...
We investigated the effect of benthic substratum type (sand and rocks) nutrient supply (N P) on biofilm structure heterotrophic metabolism in a field experiment forested Mediterranean stream (Fuirosos). Rock sand colonization formation was intensively studied for 44 d at two reaches: control experimental (continuous addition phosphate, ammonia, nitrate). Structural (C, N, polysaccharide content bacterial chlorophyll density) metabolic parameters ( β‐glucosidase, peptidase, phosphatase enzyme...
