Bivalves

In bioturbation literature, it is often assumed that microbially-mediated processes have been affected by bioturbation, with no analysis of the microbial community (Kristensen, 1984, Kristensen, 1985, Kristensen and Blackburn, 1987, Gilbert et al., 1998, Christensen et al., 2000, Michaud et al., 2006, Bonaglia et al., 2014). For example, variations in microbial nutrient remineralisation (Renz and Forster, 2013), and declines in sediment functioning under reduced pH conditions (Widdicombe and…

Kingdom: Animalia Phylum: Porifera Classification information for Poriferans: Poriferans, better known as sponges, consist of 5000 known species, all located primarily in marine and fresh waters (Myers, 2001a). They are multicellular, heterotrophic, invertebrates with an irregular shape and no distinct pattern of symmetry (Myers, 2001a). Overall, they are the simplest of animals; thus, lacking any true tissue and/or germ layers (Myers, 2001a). Furthermore, they are known to be highly sessile,…

ntroduction The development of the oyster aquaculture become limited as there is a presence of the pathogenic associated microbe that can cause disease which lead to physiological and imbalance in that oyster. There is a few reports that describe the bacterial diversity which is poorly know and required to be further study.(Hernández and Olmos,2006). So, it is important to analyze the bacteria of oyster. This study is carry out to analyze the gram positive bacteria diversity present oyster,…

English teachers should have better vocabulary knowledge so that it will help us to deliver our teaching effectively. Once we have a wide vocabulary list especially the bombastic words with reference to the thesaurus and dictionary, therefore, it will make us more confident in the classroom teaching. In morphology, morpheme can be combined to other morphemes to form a new word. Morpheme refers to the smallest unit grammatical unit in a language. For example, the word cats have two morphemes. Cat…

Maggie McMahon APES Period 1 October 24, 2014 Coral Reef Ecology Activity (#3) Tourists scenario: Tourists bring business to many of the countries that are surrounded by coral reefs, but the damage they do is putting the future of both tourism and the coral reef in jeopardy. Most people do not realize how fragile the reef is and carelessly destroy it without thinking, as ecologists have discovered patches of dead coral in the shape of diver's footprints. Boat anchors can break off a quarter…
