Biomanipulation Biomanipulation Biomanipulation is the deliberate alteration of an ecosystem by adding or removing species, especially predators. Changing the fish population of bodies of water as a part of watershed management can facilitate desirable changes in aquatic ecosystems suffering from eutrophication characterized by domination by phytoplankton aiding ecosystem restoration, an application of restoration ecology. In ponds or lakes alternative stable conditions, one with high algae populations, little other plant life, and turbid water, another with low algae populations, a diverse plant population, and clear water, may exist. In addition to prevention of excess nutrients such as phosphorus and nitrates, removal of
Artificial cartilage field. Artificial cartilage is a new research topic and much is still unknown. There is a lot of unknown factors involving ASCPs and more studies need to be conducted to make a more supported conclusion about the regenerative functions of ASCPs. Additionally, growth factors have been thoroughly evaluated, however specific combinations still need to be studied further in order to more effectively generate a tissue that can mimic the properties of natural cartilage. Artificial cartilage Artificial cartilage is a synthetic material made of hydrogels or polymers that aims to mimic the functional properties of natural cartilage in the human body.
