Biogenic Habitats

Artificially induced changes in landscape-scale habitat increase and directly affect regional diversity and systemic function (Vitousek et al., 1997, Duarte, 2002, Lozte et al., 2006 and Airoldi & Beck , 2007). Changes in natural landscape can result in loss of habitats or more complex transitions from shellfish and seagrass bed to more complex habitats to tidal flats (Short and Wyllie-Echeverria 1996, Hughes et al . 2002, Ruesink et al. 2005). , Thrush et al.

Harrison et al. (2008) They discovered that they confirmed and quantified histamine as the endogenous biogenic amine of C. virginica in the nervous system and innervating organism ... Histamine was found in various invertebrates It is known that biogenic amines are involved in local immune responses and regulate the physiological functions of the intestines and in particular also act as sensory neurotransmitters. It is obtained with gastropods. Except for the limited report that it is identified by the ganglion or nerve fiber of the Baltic Sea hernia, there are very good studies but there are few reports or bimodes in the bivalve. Crassostrea virginica, which includes dopamine, serotonin and other biogenic amines in its nervous tissue and peripheral tissues, "They also said," The mantle bivalve is a sensory structure containing various senses. Receptor Virginia State. "

Hydrocarbons from the marine environment are divided into two categories. First, biological-originated hydrocarbons (biological, natural) synthesized by marine organisms are used as various fish, plankton, and algae, but these biological compounds are not particularly abundant . Second, exogenous (artificial, offsite) compounds enter the ocean from the atmosphere, maritime traffic, tanker accidents, refineries, industrial water and municipal sewage. Aromatic compounds, especially polycyclic aromatic hydrocarbons (PAH) are characteristic of petroleum. Marine organisms do not synthesize these compounds. Hydrocarbons of anthropogenic origin can cause changes in marine animals and plants. Marine organisms can accumulate petroleum hydrocarbons in their bodies

It is usually abiotic (not due to the activities of living organisms). IMA clearly excludes biological substances. "Biomass is a chemical compound that is completely produced by biological processes without geological elements (eg urinary stones, oxalate crystals in plant tissues, shells of marine mollusk, etc.), regarded as minerals In case the geological process contains the origin of the compound, the product is recognized as a mineral.The mineral classification scheme and its definition evolve to the latest progress of mineral science. Includes the addition of organic classes to the new Dana classification and the Strunz classification scheme.Organizations include very rare minerals and hydrocarbons
