  1. 1. Ecological impacts of dam removal in Swedish inland waters : Effects on water chemistry and fish demography

    University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

    Author : Johanna Ekman; [2023]
    Keywords : biology; ecology; dam removal; Sweden; impact; inland waters; ecosystem; water chemistry; fish demography; Perca fluviatilis; European perch; biologi; ekologi; dammutrivning; Sverige; påverkan; inlandsvatten; ekosystem; vattenkemi; fiskdemografi; Perca fluviatilis; abborre;

    Abstract : Dams play an important role in our society, but their negative impacts on aquatic ecosystems have led to a need for conservation efforts to mitigate the negative effects. In some instances, dam removal has been suggested to be the most economically and ecologically beneficial restoration method to improve longitudinal connectivity. READ MORE

  3. 2. Dissolved organic matter (DOM) quality in agricultural streams and its impact on carbon dioxide concentrations in stream water

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Karin Broqvist; [2018]
    Keywords : DOM quality; dissolved organic matter; DOC; PARAFAC; fluorescence; streams; agriculture; fluorescence index; freshness index; humification index; carbon dioxide; DOM kvalitet; löst organiskt material; DOC; PARAFAC; fluorescens; bäckar; jordbruk; fluorescence index; freshness index; humification index; koldioxid;

    Abstract : Inland waters have lately been recognized to be an important component in the carbon cycle, having a significant role in carbon sequestration and carbon dioxide (CO2) emissions. Attention has also been drawn to the impact of the quality (i.e. composition and source) of dissolved organic matter (DOM) on CO2 production. READ MORE

  4. 3. XRF-as a tool for monitoring of biocide load in boatyards : Case study on two boatyards in Lake Mälaren

    University essay from Stockholms universitet/Institutionen för miljövetenskap och analytisk kemi

    Author : Matz Norling; [2015]
    Keywords : ;

    Abstract : The aim of this study was to assess the suitability of a special application to a Field Portable, handheld X-Ray Fluorescence (FPXRF) analyzer for monitoring of boatyards with focus on biocide load on boat hulls. In addition, the instrument was used for investigating the spatial distribution of contaminants in soil and sediments. READ MORE

  5. 4. Impact of photo-chemical processing of dissolved organic carbon on the bacterial respiratory quotient in aquatic ecosystems

    University essay from Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Lina Allesson; [2015]
    Keywords : bacterioplankton respiration; physical geography; biogeochemistry; photo-oxidation; degradation; nutrients; Earth and Environmental Sciences;

    Abstract : Dissolved organic carbon (DOC) enters inland waters from the surrounding terrestrial ecosystems, and is assimilated by bacterioplankton, mineralizing it to carbon dioxide (CO2). This bacterial respiration (BR) is an important part of carbon processing in freshwater, but it is also a process of global significance; in oceans and inland waters combined, BR is probably the largest single sink of organic carbon on Earth.
