Rivers are important ecosystems under continuous anthropogenic stresses. The hyporheic zone is a ubiquitous, reactive interface between the main channel and its surrounding sediments along river network. We elaborate on physical, biological, biogeochemical drivers processes within that have been studied by multiple scientific disciplines for almost half century. These previous efforts shown modulator most metabolic stream serves as refuge habitat diverse range of aquatic organisms. It also...
Abstract Forecasting long‐term consequences of global warming requires knowledge on thermal mortality and how heat stress interacts with other environmental stressors different timescales. Here, we describe a flexible analytical framework to forecast risks by combining laboratory measurements tolerance field temperature records. Our incorporates physiological acclimation effects, temporal scale differences the ecological reality fluctuations in temperature, factors such as oxygen. As proof...
Abstract Protozoan predators form an essential component of activated sludge communities that is tightly linked to wastewater treatment efficiency. Nonetheless, very little known how protozoan predation channelled via bacterial affect ecosystem functioning. Therefore, we experimentally manipulated pressure in activated-sludge determine its impacts on microbial diversity, composition and putative functionality. Different components diversity such as taxa richness, evenness, genetic beta all...
Abstract Reservoirs act as carbon sinks when sedimentation of particulate organic (POC) exceeds CO 2 and CH 4 emissions. Here, we study the poorly explored process where phytoplankton‐derived acidic polysaccharides (APs) aggregate into matter, promoting export to sediments. This source POC in sediments can mineralize over various timescales. Our research, centered on a Mediterranean reservoir, elucidates phenological trends APs identifies their predominant drivers. findings present...
A current controversy in ecology is whether biological communities are discrete entities or simply study units created for convenience; a debate that becomes even more heated when delimiting along ecotones. Here, we report an interdisciplinary designed to address the interplay between environmental drivers and community typical ecotone ecosystem: streambed. Environmental filtering at micro-scale determined how diversity, productivity composition of whole streambed assemblage varied with...
Abstract Local adaptation is commonly cited to explain species distribution, but how fitness varies along continuous geographical gradients not well understood. Here, we combine thermal biology and life‐history theory demonstrate that Drosophila populations a 2500 km latitudinal cline are adapted local conditions. We measured heat tolerance viability rate across eight varied with temperature in the laboratory then simulated their expected cumulative Darwinian employing high‐resolution data...
Thermal acclimation is presumed to affect heat tolerance, though it unclear how this should impact populations under realistic natural conditions. In study, we quantified thermal affects tolerance landscapes in Drosophila and, as a consequence, their predicted mortality the field based on modelling with dynamic algorithm. We measured of four species (D. repleta, D. hydei, simulans and virilis) acclimated five constant temperatures covering range from 18 30°C. then combined information...
We present the results of a study food web Mediterranean river in four seasons year. A high-resolution taxonomic description has been produced to characterise different community components. have also determined trophic relationships among organisms by analysing their gut contents. From network topology, we extracted several descriptors structural complexity comunity terms number nodes and links. found positive relationship between connectance diversity (both biological functional)....
Abstract The bed of fluvial ecosystems plays a major role in global biogeochemical cycles. All sediments migrate and although responses aquatic organisms to such movements have been recorded there is no theoretical framework on how the frequency sediment movement affects streambed ecology biogeochemistry. We here developed describing moving‐resting frequencies fine‐grained constrain communities across spatial scales. Specifically, we suggest that most drastic impact benthic hyporheic will...
Understanding how species adapt to different temperatures is crucial predict their response global warming, and thermal performance curves (TPCs) have been employed recurrently study this topic. Nevertheless, fundamental questions regarding thermodynamic constraints evolution interact shape TPCs in lineages inhabiting environments remain unanswered. Here, we
Abstract Extreme hydrological and thermal regimes characterize the Mediterranean zone can influence phenology of greenhouse gas (GHG) emissions in reservoirs. Our study examined seasonal changes GHG a shallow, eutrophic, hardwater reservoir Spain. We observed distinctive patterns for each gas. CH 4 substantially increased during stratification, influenced predominantly by increase water temperature, net ecosystem production, decline mean depth. N 2 O mirrored 's trend, significantly...
Litter breakdown in the streambed is an important pathway organic carbon cycling and energy transfer biosphere that mediated by a wide range of organisms. However, most research on litter to date has focused small fraction taxa drive it (e.g. microbial vs. macroinvertebrate-mediated breakdown) been limited benthic zone (BZ). Despite importance hyporheic (HZ) as bioreactor, little known about what, or who, mediates this compartment whether rates differ between BZ HZ. Here, we explore...
Abstract In this work we present the results of a one‐year study on macroinvertebrate community in an intermittent stream southern Spain. We have studied taxonomic composition, diversity and food web monthly order to consider temporal variability these parameters. More than 60 taxa been recorded stream, but they do not cohabit at same time. Many them join beginning wet period. Afterwards, some new incorporate others disappear. This leads huge fluctuations different sampling dates. These...
Abstract Food web studies provide a useful tool to assess the organization and complexity of natural communities. Nevertheless, seasonal dynamics food properties, their environmental correlates, potential association with community diversity stability remain poorly studied. Here, we condensed an incomplete 6‐year dataset subtropical coastal lake examine how monthly variation in impacts structure over idealized time series for averaged year. Phytoplankton, zooplankton, macroinvertebrates,...
Abundance–body mass (N–M) relationships are prominent macroecological patterns and provide an integrated measurement of the structure energy flow through natural communities. However, little is known about how N–M constrained by local environmental conditions. Here, we quantify sediment depth direction surface–groundwater exchange (vertical hydrodynamics), two major drivers streambed ecology, determine scaling in a sandy lowland European stream. Streambed assemblages included flagellates,...
Recently there has been increasing concern over the vast array of emerging organic contaminants (EOCs) detected in streams and rivers worldwide. Understanding ecological implications these compounds is limited to local scale case studies, partly as a result technical limitations lack integrative analyses. Here, we apply state-of-the-art instrumentation analyze complex suite EOCs streambed 30 UK their effect on communities. We abundance–body mass (N–M) relationship approach an metric...
Here we combined controlled experiments and field surveys to determine if estimates of heat tolerance predict distributional ranges phenology different Drosophila species in southern South America. We contrasted thermal death time curves, which consider both magnitude duration the challenge estimate tolerance, against range where populations are viable based on an 8-year longitudinal study. observed a strong correspondence physiological limits, niche for population growth, geographic across...
Abstract. Saline and intermittent inland lakes play a key role in the global carbon cycle, acting as dynamic zones for atmospheric exchange. Given decline of saline expected increase periods drought climate change scenario, changes are their potential capacity to uptake or emit carbon. In this study, we conducted continuous measurements CO2 CH4 fluxes at ecosystem scale within endorheic lake Mediterranean region over nearly 2 years. Our focus was on determining net exchanges with atmosphere...
Allochthonous leaf litter from riparian vegetation represents the main energy source in small lotic systems, where canopy limits autochthonous primary production. In this study, packs of two tree species (the native Salix neotrichia and introduced Populus x canadensis) were positioned Fardes Stream (southern Spain) to analyze macroinvertebrate colonization. On dates, removed, colonizing macroinvertebrates collected identified; at same time, Surber samples characterize riverbed coenosis. Leaf...
