• The category ' without vegetation ' presents the reservoirs which were created from the old pond by removing the bottom and eliminating the littoral zone.

• Domestic intermediate hosts (cattle, sheep, goats and buffaloes) are major reservoirs for the disease in humans.

• Both sub-types of virus are thought to be able to persist in equine populations, and do not require wildlife or other reservoirs.

• Firstly, elimination of regional reservoirs of infection through control at the national level, as described above.

• Increased erosion also reduces the life of reservoirs, makes additional water treatment necessary and creates greater sludge disposal problems.

• Fish then accumulate in reservoirs from which they were caught using drop nets with a mesh size of 15 mm diameter.

• Failure to exploit fish serving as reservoirs for larval sealworms may lead to increasing abundance of the parasite in the surviving fish stocks.

• Note that a similar formulation has been introduced [3] to study a homogenous dam supplied by two reservoirs each containing two immiscible fluids.

• The use of helminthological data for estimating the state of water reservoirs.

• Such a situation can occur in reservoirs when water entering the dam first sinks to its neutrally buoyant level and then spreads laterally.

• In contrast, reducing fragmentation can increase the number of infectious contacts - both among endangered species and also with host reservoirs such as domestic livestock.

• The recognition of stress-sensitivity of fractured reservoirs raises many challenges in terms of modelling (simulation) of flow and management of hydrocarbon recovery.

• The changing epidemiology of pertussis in young infants : the role of adults as reservoirs of infection.

• Other previously unexplored environmental reservoirs should, therefore, be considered.

• Evaluating evidence for top-down regulation of zoonotic disease reservoirs.
