Marine birds and plastic pollution
The intrinsic properties and widespread presence of plastic particles in the marine environment have profound effects on birds inhabiting the world's oceans. Industrial and user-plastics composed of polystyrene, polypropylene, polyethylene, styrofoam, and polyvinyl chloride are the most prevalent forms of plastic marine pollution. Their dispersal and accumulation, in average densities of 1000 t...
متن کاملChemical Pollution and Marine Mammals
Between 1990 and 2008, a close collaboration between the Centre for Environment, Fisheries and Aquaculture Science (Cefas) and the UK Cetacean Strandings Investigation Programme (CSIP) has generated one of the largest time-series datasets on chemical contaminants in a marine mammal species the UK-stranded harbour porpoise (Phocoena phocoena). This dataset shows that some organochlorine pesticid...
متن کاملMarine Ecology Progress Series
The urgent need to reduce the intense pressure and destructive power that modern fishing practices apply to the world’s fisheries, and the oceans that support them, is now widely recognized (e.g. FAO 2002a, Hilborn et al. 2003). However, there is far less agreement over the exact levels to which fishing mortality must be reduced and over how to reduce the indirect effects of fishing (e.g. bycat...
متن کاملMarine Ecology Progress Semes
Nanoplankton and picoplankton abundance and community grazing on picoplankton were deterrnined in surnmer and autumn at several stations in a productive coastal environment (Georges Bank. NW Atlantic Ocean) and in an oligotrophic oceanic ecosystem (Sargasso Sea). Ranges of heterotrophic nanoplankton (HNAN) abundance were 1.2 to 3.6 X 103 ceils rnl-' on Georges Bank, and 2.2 to 6.8 X 10' ceiis m...
متن کاملMarine Microplankton Ecology Reading
Microbes dominate our planet, especially the Earth’s oceans. The distinguishing feature of microorganisms is their small size, usually defined as less than 200 micrometers (μm); they are all invisible to the naked eye. As a group, sea microbes are extremely diverse, and extremely versatile with respect to their abilities to make and eat food. All marine microbes are too small to swim against th...
