  1. 1. Marine Habitat Mapping Using Image Enhancement Techniques & Machine Learning

    University essay from Jönköping University/JTH, Avdelningen för datateknik och informatik

    Author : Mudasar Mureed; [2022]
    Keywords : Coral Reef; Habitat Mapping; Convolutional Neural Network; Transfer Learning; Fine Tuning; CLAHE;

    Abstract : AbstractThe mapping of habitats is the first step that is done in policies that target theenvironment, as well as in spatial planning and management. The biodiversityplans are always centered around habitats. Therefore, constant monitoring ofthese delicate species in terms of health, changes, and extinction is a must inbiodiversity plans.

  3. 2. Ecotoxicological effects on the coral endosymbiont Symbiodiniaceae of organic UV-filter chemicals

    University essay from Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : Nanna Walther; [2022]
    Keywords : Environmental toxicology; Symbiodiniaceae; miljötoxikologi; phytoplankton; UV-filter chemicals; corals; environmental biology; biology; toxicology; chemicals; sunscreen; pollution; ocean; coral bleaching;

    Abstract : Coral bleaching causes the disappearance of unique ecosystems supporting thousands of different species. The corals health depends on its relationship with its endosymbiont, the zooxanthellate Symbiodiniaceae. This mutualistic relationship can be disrupted by anthropogenic chemical pollution by inducing physiologically stress in Symbiodiniaceae. READ MORE

  4. 3. 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. 4. Coral Fungia fungites- associated microbial communities and their shifts upon anthropogenic disturbances

    University essay from Uppsala universitet/Limnologi; Uppsala universitet/Institutionen för biologisk grundutbildning

    Author : VASILIKI PAPAZACHARIOU; [2019]
    Keywords : coral microbiome; Fungia fungites; Microbiology; corals; antibiotics; 16S;

    Abstract : One of the main focus of coral reef ecology has been to shed light on the importance of all microbial members of coral holobiont and how their interactions contribute to the coral’s resilience. However, knowledge is lacking about the composition of microbial communities inhabiting the surface mucus layer of corals including Fungia fungites, a species that lives under stressful conditions close to fish farms in Vietnam.

  6. 5. Herbivores effect on coral reefs : relationships between sea urchins, coral health and algae cover

    University essay from SLU/Dept. of Ecology

    Author : Linnéa Fridén; [2019]
    Keywords : sea urchins; coral health; coral bleaching; algae cover; correlation; influence;

    Abstract : Coral reefs are vital to marine ecology. The population dynamic on coral reefs are complex and sensitive to natural and anthropogenic changes. Various factors can affect the population dynamic and inflict change. Coral bleaching is threatening coral reefs worldwide and is a hot topic in today’s climate challenges. READ MORE
