Pełny tekst źródłaHuman activity through industry, urbanization and agriculture, has led to the production and release of a large amounts of chemical compounds (including pesticides and pharmaceuticals) into the biosphere. One of the problematic related to the xenobiotic compounds fate is their transfer to aquatic ecosystems and the alteration of diversity and activity of microbial communities. Microbial communities associated with immersed leaf-litter can be impacted by these compounds, and in turn, alter global processes such as the carbon and nutrient cycling in the stream ecosystem. Accordingly, this thesis work aims to assess the effects of realistic chemical contamination on microbial leaf-litter decomposition process in streams.The first chapter of this thesis was focused on the comparison of microbial decomposition activity in alder leaves in six watersheds presenting different land uses (agricultural, urbanized, forested) over four seasons (spring, summer, autumn, winter). The effect of the gradient of contamination on microbial organic matter processing from upstream to downstream sections in each watershed was also assessed. Monitoring revealed that microbial decomposition of leaves was slightly higher in contaminated watersheds (agricultural and urbanized) in comparison with control ones (forested), probably because of the compensation effect by nutrients over xenobiotics. However, this compensation mechanism was partial since fungal biomass accumulated in leaves was greatly reduced in contaminated watersheds. Overall, this highlights microbial communities being more efficient for leaf decomposition in polluted watersheds than in the less contaminated ones, which is probably explained by changes in microbial community structure.The second chapter of this thesis aimed to evaluate in vitro the specific interactions between nutrients (nitrogen and phosphorus) and pesticides (herbicide and fungicide, alone or in mixture) exposure on microbial communities during leaf-litter decomposition. High nutrient concentrations (eutrophic conditions) tended to exacerbate the effects of pesticides on leaf decomposition rates suggesting that the compensatory mechanism of nutrients over pesticides observed in the previous part is probably concentration dependent and does not always apply to aquatic microbial communities. Moreover, a stimulation in laccase activity was observed when microbial communities were exposed to the fungicide, suggesting a role of this enzyme in detoxification mechanisms. However, the fact that such stimulation was not observed when exposed to the mixture of both pesticides (herbicide and fungicide) suggest that the interaction between these two molecules impaired the ability of microbial communities to display properstress response. These results constitute the first evidence of the potential interaction between an herbicide and a fungicide on leaf-associated microbial communities functioning. (...)

Pełny tekst źródłaEn aquesta tesi s’han estudiat els factors ambientals determinants i els mecanismes microbians involucrats en la descomposició de fullaraca en rius intermitents mediterranis. També s’ha avaluat l’efecte de la sequera en rius intermitents mediterranis i permanents atlàntics. En el riu intermitent mediterrani la descomposició de fullaraca s’ha vist afectada per la variació anual de la temperatura, conductivitat i velocitat de la corrent. La sequera clarament va determinar canvis en els microorganismes descomponedors i el seu funcionament en ambdós tipus de rius, malgrat no sempre va afectar la velocitat de descomposició. Els resultats suggereixen que en condicions extremes de variació ambiental i sequera, esperats pel canvi global, els microorganismes descomponedors de la fullaraca es veuran molt afectats. No obstant, les conseqüències en el reciclatge de carboni dependran del tipus de pertorbació relacionada amb la sequera, de la interacció amb altres impactes i de les comunitats descomponedores prèvies que habiten al riu.

Pełny tekst źródłaPara comprender cómo funciona la dinámica de la hojarasca en arroyos, la presente tesis pretende examinar (a) cómo las características hidro-morfológicas del lecho del arroyo pueden influir en la retención, distribución espacial, fragmentación física y descomposición de la hojarasca. Además, también examinamos (b) la interacción entre el procesamiento de hojarasca y la dinámica del carbono orgánico disuelto y nitrógeno inorgánico disuelto del arroyo y cómo varía dependiendo de las especies de hojarasca consideradas. La presente tesis revela que la heterogeneidad de la velocidad del agua dentro de un tramo es un factor que controla diferentes aspectos de la dinámica de hojarasca en arroyos, ya que no solo influye en la fracción de hojarasca retenida, sino también en cómo estas entradas se distribuyen espacialmente y se procesan en los arroyos. Por lo tanto, indicamos que la relevancia de las entradas de hojarasca como fuente de materia orgánica para las comunidades del arroyo puede estar sujeta a las características hidro-morfológicas de dicho ecosistema, ya que determinan la heterogeneidad espacial de la velocidad del agua dentro del mismo. Además, sugerimos que la calidad de la hojarasca influye en las propiedades químicas y estructurales de los lixiviados de hojarasca y también cómo estos lixiviados son utilizados por los microorganismos del arroyo. La calidad de la hojarasca también puede dictar las demandas microbianas de C y N disuelto de la columna de agua. Finalmente, sugerimos que la influencia de las concentraciones de nutrientes del arroyo en la descomposición de la hojarasca puede estar sujeta a la calidad de la hojarasca. Teniendo en cuenta todos nuestros resultados, sugerimos que la composición del bosque de ribera, que determina la calidad de las entradas de hojarasca, puede controlar el vínculo entre el procesamiento de la hojarasca y la dinámica de solutos C y N del arroyo. Sin embargo, la heterogeneidad de la velocidad del agua puede ser el factor más relevante para determinar la importancia de la hojarasca en las corrientes, ya que puede controlar la probabilidad de que las hojas queden retenidas en el arroyo o se exporten aguas abajo, perdiéndose como fuente de materia y energía.
