Ocean ecosystems consist of the world's oceans, encircling small water bodies such as river basins and estuaries to the large ones such as seas and oceans. Their area is measured in terms kmÂ², and are studied in terms of bathymetry and hydrography. Ocean ecosystems must be protected and preserved as the worldâs ocean waters are degraded hugely by indefensible fishing practices, habitat degradation of marine organisms, eutrophication, water pollution, aerosol contamination, etc. The degradation could be prevented by recuperating exhausted fish populations, restoring the degraded habitats and reducing the coastal pollution. The degradation of marine or coastal ecosystem is immensely affecting the world's yearly saltwater fishery yields.Review articles are the summary of current state of understanding on a particular research topic. They analyze or discuss research previously published by scientist and academicians rather than reporting novel research results.
Review article comes in the form of systematic reviews and literature reviews and are a form of secondary literature. Systematic reviews determine an objective list of criteria, and find all previously published original research papers that meet the criteria. They then compare the results presented in these papers. Literature reviews, by contrast, provide a summary of what the authors believe are the best and most relevant prior publications.
The concept of "review article" is separate from the concept of peer-reviewed literature. It is possible for a review to be peer-reviewed, and it is possible for a review to be non-peer-reviewed.
