ECOLOGY HABITATS

Over the last few hundred years there has been large-scale loss of wetland environments in rivers and estuaries throughout the world due to development pressures and flood control measures. The continued loss of wetlands removes valuable ecological habitats and also reduces the capacity for both carbon storage and nutrient removal by the processes described above. In the Humber estuary (UK), more than 90% of the intertidal marshes and supratidal wetlands have been lost to land reclamation over the last 300 years or so, resulting in a 99% reduc-... 

The greater the amount of carbon dioxide injected, the more will return to the surface with the methane. This creates the need for a gas-separation plant of the type shown in Figure 3.2. The removal of carbon dioxide from oil is much simpler than from methane, which is why enhanced oil recovery is practised more widely than enhanced gas recovery. With an extensive coal seam, it will be necessary to drill injection and extraction wells every few hundred metres or so. These, together with the associated gas compressors, distribution pipes and pumps, access roads, etc., will turn a rural landscape into an industrial site. When the operational/safety issues and the extent of industrialization become fully appreciated, not to mention the impact on the ecological habitat, there may well be local opposition to the recovery of coal-bed methane - with or without carbon dioxide injection and storage. 

The three major groups of fungi producing ochratoxin A have quite different physiology and consequently quite different ecological habitats. To understand the... 

From this viewpoint, the natural environments should be better identified, in terms of ecological habitats, and test approaches should in turn be based on the typical conditions experienced by the plastic products when entering each habitat, since the microbial population (and thus biodegradation activity) could be quite different. Tosin and co-workers [13] have identified 6 habitats where plastic waste can reside when littered in the marine environment 1) pelagic domain (the plastic products float freely in estuaries and the open ocean water), 2) eulittoral zone (tides and storm waves bring great quantities of plastic waste to the shoreline, where plastic products get partly buried and kept wet by tidal inundation and waves), 3) supralittoral zone (the plastic products are washed onto the beach, exposed to a sandy soil with a low moisture level), 4) sublittoral zone (plastic products settle on marine sandy sediment where they are exposed to the seawater/sediment interface), 5) plastic products can otherwise sink to the bottom of the deep sea and 6) plastic products can be slowly buried within sediments on the sea-floor. 

Sensitive Ecology (habitats and species ) - are present and defined within 20km of the site, with many present within 10km or less these include European designated sites (including Special Areas of Conservation (SAC), Special Protection Area (SPA), wetland of international importance ( Ramsar site ), and UK designated Site of Special Scientific Interest (SSSl)).
