Abstract When antimicrobial resistant bacteria (ARB) and genes (ARGs) reach novel habitats, they can become part of the habitat’s microbiome in long term if are able to overcome biotic resilience towards immigration. This process should more difficult with increasing biodiversity, as exploitable niches a given habitat reduced for immigrants when diverse competitors present. Consequently, microbial diversity could provide natural barrier resistance by reducing persistence time immigrating ARB...
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...
Surface-groundwater interactions in intermittent rivers and ephemeral streams (IRES), waterways which do not flow year-round, are spatially temporally dynamic because of alternations between flowing, non-flowing dry hydrological states. Interactions surface groundwater often create mixing zones with distinct redox gradients, potentially driving high rates carbon nutrient cycling. Yet a complete understanding how underlying biogeochemical processes across surface-groundwater flowpaths IRES...
Abstract Spatial and temporal widening of drought periods together with occurrence flash storm events are consequences global change affecting temporary stream ecosystems. Streambed heterotrophic microbes the key biogeochemical processes they carry on could be endangered by strengthening episodes. Here, we performed a 165‐day experiment through 12 streambed sediment columns to study microbial functional structural responses long‐term drought. Two depths (surface hyporheic) leaf litter were...
Abstract Microbial biodiversity is fundamental to maintain ecosystem functioning in seasonally variable ecosystems. However, it remains unclear how alterations water availability caused by episodic drying compromise the ability of stream microbes multiple functions simultaneously (e.g., primary production and carbon cycling). Using data from 32 streams, we investigated phenology annual influences sediment microbial their capacity sustain multifunctionality. Our results showed that...
Abstract Stream microbes that occur in the Mediterranean Basin have been shown to possess heightened sensitivity intensified water stress attributed climate change. Here, we investigate effects of long-term drought (150 days), storms and rewetting (7 days) on diversity composition archaea, bacteria fungi inhabiting intermittent streambed sediment (surface hyporheic) buried leaves. Hydrological alterations modified archaeal community more than bacterial composition, whereas were least...
Abstract Background In the environment, microbial communities are constantly exposed to invasion by antimicrobial resistant bacteria (ARB) and their associated resistance genes (ARGs) that were enriched in anthroposphere. A successful invader has overcome biotic resilience of habitat, which is more difficult with increasing biodiversity. The capacity exploit resources a given habitat enhanced when exhibit greater diversity, reducing opportunities for invaders, leading lower persistence....
Microbes inhabiting intermittent streambeds are responsible for controlling and developing many biogeochemical processes essential the ecosystem functions. Although streambed microbiota is adapted to intermittency intensification of water scarcity prolonged dry periods may jeopardise their capacity cope with hydrological changes. This study aims evaluate whether, what extent, duration affects microbial density, diversity, composition (16S rRNA gene diversity) functions (extracellular enzyme...
Coastal marsh lagoons are of high ecological relevance playing a key role in the carbon cycle but threatened to disappear due global change effects. Restoration practices can counteract this process. This study compares microbial heterotrophic functioning three "new" man-made (created 2016) that "old" (two natural plus one created 2002) from Mediterranean coastal marsh. The activity range extracellular enzymes, functional diversity, and dissolved organic matter (DOM) quality, together with...
Aquatic fungi are highly diverse organisms that play a critical role in global biogeochemical cycles. Yet it remains unclear which assembly processes determine their co-occurrence and patterns over gradients of drying intensity, is common stressor fluvial networks. Although aquatic possess drying-specific adaptations, little known about how functional similarity influences probability traits sorted by drying. Using field data from 15 streams, we investigated responded to intensity. To do so,...
As motivation to address environmental dissemination of antimicrobial resistance (AMR) is mounting, there a need characterize mechanisms by which AMR can propagate under conditions. Here we investigated the effect temperature and stagnation on persistence wastewater-associated antibiotic markers in riverine biofilms invasion success genetically-tagged Escherichia coli. Biofilms grown glass slides incubated in-situ downstream wastewater treatment plant effluent discharge point were...
Abstract Background Antibiotic resistance, which is mediated by environmental reservoirs, poses a threat to human and animal health. Aquatic biofilms impacted treated wastewater (WW) are known reservoirs for antibiotic however the specific influence of biotic factors abiotic from WW on abundance resistance genes (ARGs) within aquatic remains unclear. Additionally, experimental evidence limited as whether with low sequence similarity reference ARGs actually encode functional ARGs,...
Hydrological drought, characterized by a significant deficiency in rainfall events, promotes natural desiccation processes. The reduction water recharge and the loss of freshwater ecosystems pose urgent challenges face increasing global population escalating demand for resources. variability duration no-flow periods can have profound implications ecosystem functioning, specifically impacting microbiota residing streambed sediments vital processes they perform. serves as an ecotone where...
