This dissertation has as its goal the quantitative evaluation of the application of<br/>coupled hydrodynamic, ecological and clarity models, to address the deterministic prediction of water clarity in lakes and reservoirs. ...
The work presented in this Doctoral Thesis has studied the temporal and spatial patterns of the most relevant soil parameters with special attention posed to soil biological and biochemical dynamics occurring at the studied ...
We study the effect of organic farming practices on several taxa in olive groves and vineyards. Sessile organisms show a stronger response to treatment, their diversity being higher in organic vineyards. Vagile organism ...
Antibiotic residues in the environment are amongst the most concerning micropollutants due to their potential impact on the natural ecosystems and human health. In this thesis, laboratory and field studies were conducted ...
The present thesis aims to evaluate the use of antioxidant enzyme activities (AEA) of biofilm communities as biomarkers of metal pollution (mainly Zn) in fluvial ecosystems. In order to test AEA as biomarkers of metal ...
El presente estudio tiene como objetivo proporcionar una base de conocimiento sólida para la restauración ecológica de ríos, basada en la respuesta de comunidades acuáticas a cambios en la conectividad hídrica, factores ...
Based on the current knowledge about biofilm ecotoxicology and arsenic biogeochemistry in freshwater ecosystems, this thesis studied, under realistic environmental concentrations, i) the role of benthic biofilms in the ...
Hydrological drought is a process of natural desiccation mainly due to large shortage of rainfall events. Reduced precipitations and prolonged droughts are spreading worldwide and threaten the integrity of aquatic ...
La comunitat bentònica dels ecosistemes fluvials processa una gran quantitat de la matèria orgànica que arriba als rius. L'origen de les entrades de material (autòctones o al·lòctones), la seva composició química i la seva ...
Coastal wetlands and lagoons are some of the most fluctuating and productive ecosystems in the world. As transition zones between marine and continental environments, they provide numerous ecosystem services, including the ...
ENG- Pharmaceuticals have been broadly detected in aquatic systems, including rivers, lakes, and coastal areas. Their widespread occurrence and accumulation in aquatic organisms have raised concerns about their ecotoxicological ...
Currently, global change is promoting the spatiotemporal occurrence of temporary streams, altering fluvial ecosystem function and structure, and the ecosystem services they provide. To effectively protect fluvial ecosystems, ...
The main goal of this thesis is to investigate the effects of consequences of global change on fluvial biofilms. To achieve this objective a multi-marker approach has been used at different experimental scales. Our results ...
La família de les Rosaceae comprèn espècies d’alta rellevància econòmica, com ho són les espècies de fruiters de clima temperat, ornamentals i medicinals. El seu cultiu, però, es veu limitat per la propagació de diversos ...
A direct consequence of sea warming in the Mediterranean is a increase in the abundance of thermo-tolerant species fish species such as Sphyraena viridensis, Pomadasys incisus, Pomatomus saltatrix and Trachinotus ovatus. ...
El estudio de las comunidades de cianobacterias en la cuenca del río Muga permite profundizar en la búsqueda de factores que favorezcan o inhiban la acumulación intracelular de microcistinas y su liberación al medio externo ...
Inland waters are amongst the most diverse and impacted ecosystems globally, and they host many endangered taxa. Cyprinodontiforms are at the forefront of endangered freshwater fishes in Europe, with more than 80% of the ...
Pyrenean headwater streams are singular ecosystems with a particular seasonal pattern. They sustain a unique biodiversity especially sensitive to environmental change. Because of this, their ecosystem structure and function ...
Per tal d’avaluar l’impacte de la contaminació en els ecosistemes aquàtics, aquesta tesi es centra en una aproximació multi-biomarcador en els biofilms. En complement dels biomarcadors clàssics, es va demostrar que les ...
Les algues del gènere Cystoseira són els principals organismes formadors d'estructura en fons rocosos ben il·luminats del Mar Mediterrani. Formen unes comunitats molt estructurades que s'assemblen ecològicament als boscos ...
