  1. 1. 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.

  2. 2. Effects of native freshwater mussels and leaf debris on benthic macroinvertebrate abundance and diversity : A field experiment with Margaritifera margaritifera in Vasslabäcken, Örebro county

    University essay from Karlstads universitet/Institutionen för miljö- och livsvetenskaper (from 2013)

    Author : Kai Sven Onken; [2021]
    Keywords : bivalve; functional role; habitat modification; decomposition; biodeposition;

    Abstract : Organisms that are part of complex ecosystems interact not only with other organisms but also with their environment, affecting ecosystem functions. In aquatic ecosystems filter feeders affect ecosystem functioning by transferring energy and nutrients from the water to the benthos. READ MORE

  3. 3. Estimating the Early Evolution of Brachiopods Using an Integrated Approach Combining Genomics and Fossils

    University essay from Uppsala universitet/Paleobiologi

    Author : Chloé Robert; [2019]
    Keywords : Brachiopoda; evolutionary history; phylogeny; Maximum likelihood; Bayesian inference; fossil calibrations; Brachiopoda; evolutionhistoria; fylogeni; Maximum likelihood-metoden; Bayesiansk statistik; fossilkalibering;

    Abstract : The Brachiopoda, a major group of the Lophotrochozoa, experienced a rapid early evolutionary diversification during the well-known Cambrian explosion and subsequently dominated the Palaeozoic benthos with its diversity and abundance. Even though the phylogeny of the Lophotrochozoa is still hotly debated, it is now known that the Brachiopoda are a monophyletic grouping. READ MORE

  4. 4. The Establishment of Macrobenthic Faunal Communities in Planted Mangroves of Increasing Age

    University essay from Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Author : Simon Jacobsen Ellerstrand; [2017]
    Keywords : Benthos; Shannon-diversity; forestation; biodiversity; ecosystem engineers; development issues; Biology and Life Sciences;

    Abstract : The mangrove ecosystem is a tropical coastal community inhabited by organisms adapted to the stressful environment of the tidal zone. Mangrove ecosystems has in recent years been noted for the important ecosystem services they offer. READ MORE

  5. 5. Light, temperature and competition : understanding the causes for climate-driven regime shifts in arctic marine benthos

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Kim Scherrer; [2015]
    Keywords : macroalgae; light; invertebrate; coralline algae; Arctic; benthic; regime shift; climate change; marin ekologi; tång; kalkalg; Arktis; regimskifte; klimatförändring; ljus;

    Abstract : In the Arctic, shallow sea-floor communities have been documented to shift abruptly from an invertebrate-dominated state to a state with high macroalgal abundance. Climate warming, resulting in increased water temperatures and decreased sea ice cover, could trigger such regime shifts in benthic ecosystems, but the underlying mechanisms are not clear. READ MORE
