  2. Marine coastal ecosystem - Wikipedia

    en.wikipedia.org/wiki/Marine_coastal_ecosystem

    Ecosystem services delivered by epibenthic bivalve reefs Bivalve reefs provide coastal protection through erosion control and shoreline stabilization, and modify the physical landscape by ecosystem engineering , thereby providing habitat for species by facilitative interactions with other habitats such as tidal flat benthic communities ...

    Ecosystem services delivered by epibenthic bivalve reefs. Reefs provide coastal protection through erosion control and shoreline stabilization, and modify the physical landscape by ecosystem engineering , thereby providing habitat for species by facilitative interactions with other habitats such as tidal flat benthic communities, seagrasses and ...

  4. Bivalvia - Wikipedia

    en.wikipedia.org/wiki/Bivalvia

    Ecosystem services provided by marine bivalves in relation to nutrient extraction from the coastal environment have gained increased attention to mitigate adverse effects of excess nutrient loading from human activities, such as agriculture and sewage discharge. These activities damage coastal ecosystems and require action from local, regional ...

  5. Ecosystem service - Wikipedia

    en.wikipedia.org/wiki/Ecosystem_service

    Ecosystem services are the various benefits that humans derive from healthy ecosystems. These ecosystems, when functioning well, offer such things as provision of food, natural pollination of crops, clean air and water, decomposition of wastes, or flood control. Ecosystem services are grouped into four broad categories of services.

  6. Marine food web - Wikipedia

    en.wikipedia.org/wiki/Marine_food_web

    An ecosystem may experience a dramatic shift if a keystone species is removed, even though that species was a small part of the ecosystem by measures of biomass or productivity. [158] Sea otters limit the damage sea urchins inflict on kelp forests. When the sea otters of the North American west coast were hunted commercially for their fur ...

  7. Freshwater bivalve - Wikipedia

    en.wikipedia.org/wiki/Freshwater_bivalve

    Freshwater bivalves are molluscs of the order Bivalvia that inhabit freshwater ecosystems. They are one of the two main groups of freshwater molluscs , along with freshwater snails . The majority of bivalve molluscs are saltwater species that live in the marine habitats , but a number of families have evolved to live in fresh water (and in some ...

  8. Human interactions with molluscs - Wikipedia

    en.wikipedia.org/wiki/Human_interactions_with...

    Bivalve molluscs are used as bioindicators to monitor the health of aquatic environments in both fresh water and the marine environments. Their population status and structure, physiology, behaviour and their levels of contamination with chemicals together provide a detailed indication of the status of the ecosystem.

  9. Marine invertebrates - Wikipedia

    en.wikipedia.org/wiki/Marine_invertebrates

    There are about 8,000 marine bivalves species (including brackish water and estuarine species), and about 1,200 freshwater species. Cephalopod include octopus , squid and cuttlefish . They are found in all oceans, and neurologically are the most advanced of the invertebrates. [ 59 ]
