Marine biology is a hybrid subject that combines aspects of organismal function, ecological interaction and the study of marine biodiversity.[1] The earliest studies of marine biology can be traced back to the Phoenicians and the Greeks who are known as the initial explorers of the oceans and their composition.[2] However, it was Aristotle (384-322 BC) who was the first to record any observatio...

Marine organisms modify the distribution of radioisotopes in the oceanic ecosystem. Various vital processes of plants and animals concentrate elements. The distributions of the biota are often independent of their watery environment; they may actively migrate vertically or horizontally or may remain in place while the water moves past them. In the case of plankton, the concentrating organisms p...

Marine birnavirus (MBVs) infect a wide range of fish and shellfish. Yet their mode of transmission is still unclear. To determine marine plankton serve as a vector for MABVs. The marine birnavirus (MABVs) is a member of Aquabirnavirus and an opportunistic pathogenic form among eukaryotic marine organisms and determine the viral presence in zooplankton as a vector, molecular diagnosis can be use...

Almost all ICES member countries have policies that address the impacts of human activities on marine ecosystems. These policies may explicitly be framed as an implementation of an ecosystem approach. An important example is the Marine Strategy Framework Directive (MSFD) of the European Union (EC, 2008), which is a comprehensive framework for achieving good environmental status (GES) for Europe...

Chronic undersampling of the marine environment, including both biological and physical components, has been and remains a major block to understanding how marine ecosystems function and how they respond to changes, whether natural or anthropogenic. Consequently, data-based models that accurately predict local variations in the abundance of plant and animal life in the sea are rare or do not ex...

the spanish turbot aquaculture sector holds a top position in the international market. thisactivity is mainly developed along the galician coast (nw spain). this article evaluates the environmentalperformance of galician turbot aquaculture according to the life cycle assessment (lca) methodology.previously, on account of the expected relevance of feed for aquaculture, marine aquafeed productio...

A summary of knowledge and recommendations for the conservation of marine birds and their habitats throughout the California Current Large Marine Ecosystem.

in the first experiment, twelve species of the most plentiful and fresh seaweeds and one species of seagrass from the beach were collected at kingston, south australia. all species were then separately sun-and oven-dried and ground. the ground samples were analysed for dry matter, ash, organic matter, crude protein, crude fibers, ether extract and digestibility in vitro. the digestible and ...

The California Current Large Marine Ecosystem (CCLME), a temperate marine region dominated by episodic upwelling, is predicted to experience rapid environmental change in the future due to ocean acidification. The aragonite saturation state within the California Current System is predicted to decrease in the future with near-permanent undersaturation conditions expected by the year 2050. Thus, ...

On June 2013 a workshop at the University of Siena (Italy) was organized to review current knowledge and to clarify what is known, and what remains to be investigated, concerning plastic litter in the sea. The content of the workshop was designed to contribute further to the European Marine Strategy Framework Directive (MSFD) following an inaugural workshop in 2012. Here we report a number of s...
