[1] The oxygen isotope content of nocturnal ecosystem respiration (dOR) was examined in forests along a precipitation gradient in Oregon, USA, to determine whether site-to-site variation in dOR was more strongly related to variation in d O of precipitation or to evaporative processes that isotopically modify water pools within ecosystems. Measurements were made over 4 years at sites ranging in ...
Infectious pancreatic necrosis (IPN) is a contagious viral disease of fish that causes economic losses in aquaculture worldwide. In Finland, IPN virus (IPNV) has been isolated since 1987 from adult fish showing no signs of clinical disease at fish farms located in the coastal areas of the Baltic Sea. The inland area of Finland, however, remained free of IPN until 2012, when fish on several rain...
inland saline aquaculture may offer an opportunity for income diversification and a potentially productive use of land that can no longer support traditional agriculture in salt-affected parts of inland production and investment levels are characteristically low. it needs to develop in a manner that both prevents the further degradation of agricultural land and provides opportunities for an alt...
Palm oil mill effluent (POME) is an important source of inland water pollution when released into local rivers or lakes without treatment. In the process of palm oil milling, POME is generat‐ ed through sterilization of fresh oil palm fruit bunches, clarification of palm oil and effluent from hydro-cyclone operations [Borja et al.,1996a]. POME is a viscous brown liquid with fine suspended solid...
Background Bangladesh is basically a low lying flat land country, is endowed with enormous inland fishery resources which contribute a significant part of freshwater fish production. Inland fisheries in Bangladesh contain different types of water bodies’ character e.g. flowing rivers, beel—usually deeper depression in the floodplain, haor—extensive low lying areas comprising several perennial b...
Conventional ocean color satellites sensors are not very suitable for inland and coastal waters applications due to their low spatial resolutions. High spatial resolution satellite sensors are required to monitor the water quality of inland and coastal waters. The conventional high-resolution satellites such as Landsat, SPOT and IKONOS have limited number of spectral bands. In comparison, the W...
The strategy of passing much of European Union (EU) waste water through a sewage treatment plant (STP) before discharging it into rivers or lakes has done much to improve the quality of our inland waterways. But we still face a very worrying situation. Environmental problems have surfaced in conjunction with the STPs and their effluent recipients, and attention has turned to human pharmaceutica...
