    Author : Zehao Li; [2021]
    Keywords : Water resources engineering; Ozonation; NDMA; Wastewater; pharmaceutical; Diclofenac; Ibuprofen; Naproxen; Technology and Engineering;

    Abstract : In people’s modern life, daily usage of artificial compounds such as active pharmaceuticals ingredients (API) is usual. These compounds are likely to end up as micropollutants in the municipal wastewater. Municipal wastewater is the major source of pharmaceuticals in the aquatic environment. READ MORE

  2. 2. Quantifying the state of the coral reef ecosystem in relation to biophysical benthic and pelagic indicators and biological drivers of change in the Saba National Marine Park, Dutch Caribbean

    University essay from SLU/Dept. Of Aquatic Resources

    Author : Wiebke Homes; [2021]
    Keywords : GCRMN; Reef Health Index; ; marine protected area; fish-benthos interaction; macroalgae; herbuvory; trophic cascade; fishing; coral disease; Caribbean;

    Abstract : Coral reefs are experiencing large scale degradation. Motivated by the need for regular data monitoring and for quantification of the state and change of benthic and pelagic organisms, the Global Coral Reef Monitoring Network protocol was executed on 18 dive sites in fished and unfished areas around the island of Saba in the Saba National Marine Park (SNMP) in the Dutch Caribbean from March to May 2019.

  5. 5. Behaviour and morphology in wild guppies from populations with high and low predation pressure in Trinidad

    University essay from SLU/Dept. Of Aquatic Resources

    Author : William Harry Ashworth; [2020]
    Keywords : behavioural ecology; colouration; Poecilia reticulata; sexual ornament;

    Abstract : Behaviour and morphology can vary significantly within a species as a result of the predation pressure individuals are exposed to. Wild populations of guppies (Poecilia reticulata) exposed to high and low predation can be found in the streams of northern Trinidad, providing a useful study system for investigating how behaviour and morphology are affected by predation.
