Desktop virtualization is software technology that separates the desktop environment and associated application software from the physical client device that is used to access it.
Atmospheric deposition of reduced nitrogen onto nutrient-limited semi-natural vegetation (unimproved grasslands, heathlands, blanket bog) can cause a shift in the balance of species in these sensitive systems because the nitrogen has a nutrient effect on plant growth.
Effects on the biota Organic pollution affects the organisms living in a stream by lowering the available oxygen in the water. This causes reduced fitness, or, when severe, asphyxiation. The increased turbidity of the water reduces the light available to photosynthetic organisms.
