Biological invasions are an important threat to biodiversity especially in aquatic ecosystems, and their frequency is generally higher near urban areas. Potentially invasive non-indigenous molluscs were deliberately introduced into European waters for food (Corbicula fluminea) biocontrol (Melanoides tuberculata), unintentionally by ballast water (Mytilopsis leucophaeata, Corbicula fluminea), stock contamination (Sinanodonta woodiana), accidental escapes from aquaculture aquarium trade...
Abstract Many lakes exhibit seasonal stratification, during which they develop strong thermal and chemical gradients. An expansion of depth‐integrated monitoring programs has provided insight into the importance organic carbon processing that occurs below upper mixed layer. However, physical drivers metabolism metabolic coupling remain unresolved, especially in metalimnion. In this depth zone, sharp gradients key resources such as light temperature co‐occur with dynamic conditions influence...
Summary 1. The near‐surface distribution of phytoplankton cells along the thalweg a canyon‐shaped reservoir (El Gergal, southern Spain) during two surveys is described and interpreted as result time‐varying large‐scale circulation patterns, vertical mixing processes physiological capacity algal to regulate its position in water column. 2. Vertical gradients chlorophyll‐a concentration developed column day but disappeared at night, shoaling deepening diurnal mixed layer (dml). changes depth...
Phytoplankton spatial distribution patterns in four Andalusian reservoirs with different physical characteristics are described and evaluated this work.Both vertical horizontal presented order to demonstrate that thermally stratified dynamic, complex heterogeneus ecosystems.Vertically, phytoplankton patchiness was physically controlled by turbulent mixing light climate biologically determined the hydromechanical of each microalgae functional group.The result interaction between wind-induced...
Using a numerical model (PROTECH) to examine the impact of water transfers on phytoplankton dynamics in Mediterranean reservoirEl Gergal is last link system reservoirs located Rivera de Huelva River, Seville (South-West Spain).Because its position within and different transfer possibilities between reservoirs, florisitic composition El can be strongly influenced by concentration cells present transferred from other series.In June 2000 large Ceratium hirundinella inoculums was an upstream...

Carbon dioxide emission from drawdown areas of a Mediterranean reservoirSediment beds reservoirs constitute relevant hotspot for carbon (CO 2 ) to the atmosphere.This CO source is especially in case reservoirs, where hydrological variability favors exposure large sediment air.In spite this, role dry sediments as emitters has been typically neglected lakes and greenhouse gas assessments, there also lack research on spatial fluxes sediments.In this study we contribute knowledge by combining...
Abstract Global change is modifying meteorological and hydrological factors that influence the thermal regime of water bodies. These modifications can lead to longer stratification periods with enlarged hypolimnetic anoxic periods, which promote heterotrophic anaerobic processes alter reservoir carbon cycling. Here, we quantified aerobic (aerobic respiration, denitrification, iron manganese reduction, sulfate methanogenesis) on dissolved inorganic (DIC) production in hypolimnion a...
Environmental contextIn 2015, the European Union issued a Watch List of organic pollutants resulting from anthropogenic activities. A major obstacle to controlling these in environment is difficulty their simultaneous measurement at low concentrations. We developed an analytical method for determination surface water 17 included EU List. AbstractA multi-class was Decision 2015/495 regarding waters. The target analytes were three estrogens, four pharmaceuticals, food additive, solar filter...
Abstract – Otoliths were used to explore the timing of annulus formation in Barbus sclateri. Lapillus exhibited opaque and translucent zones whose combination was formed once a year. Opaque appeared from July January, ones February June. We describe procedure assess age by using number annulii, condition otolith’s edge capture date. The use otoliths for determination this cyprinid endemic Iberian Peninsula provides useful alternative traditional methods scale reading. Note

EMASESA has been monitoring the biological colonization in Cartuja Island raw water network since 2001. Water from Guadalquivir River dock, which circulates through this network, is meant for irrigation of green areas and air conditioning buildings 93 Science Technology Park. The results study have highlighted that distribution three exotic invasive species are involved: bivalves Mytilopsis leucophaeata Corbicula fluminea, along with hydrozoan Cordylophora caspia. principally registered at...
Abstract This is the first description of otoliths (sagitta, asteriscus, and lapillus) European barbel ( Barbus sclateri , Pisces: Cyprinidae), as well location, procedure for extracting them preparing age growth studies. The were observed by light scanning electron microscopy. With this last technique each otolith had a variable external crystalline morphology which may be related to different rates crystals. When seen through reflected light, lapillus asteriscus showed opaque translucent...
The allometric relationship between fish length and otolith radius was determined for a European barbel, Barbus sclateri, from two natural populations. significantly different populations, but did not differ females males. ages of the were otoliths, this used to evaluate four back-calculation procedures: Monastyrsky’s method direct proportion; by intercept-corrected proportion (Fraser-Lee’s biological intercept method); simple regression method. provided most reliable estimates lengths at...
