Brochure, flyer, fact-sheetSkorasnji primeri invazivnih sumskih stetocina u Evropi 2014У današnje vreme trendovi globalizacije, naročito porast trgovine, sve veće mogućnosti za putovanje i klimatske promene predstavljaju glavne činioce koji убрзавају увођење i utvrđivanje stranih vrsta.

No results found.This report is an overview over the present distribution of mangrove swamps in Thailand, and describes the kinds and extent of aquatic pollution. It reviews the recent studies of mangrove composition and occurrence of fauna and secondary flora in some mangrove forests and adjacent tidal flats. The mangrove areas are further characterized by physical and chemical data of the waters, tides, currents, temperature, and further by the types of land use. The findings of aquatic pollution from various industries are described, but concentrate naturally on the more industrialized areas around the Upper Gulf of Thailand and the Upper Gulf itself. The discussion on pollution effects on mangrove ecosystem considers riverine and sea-based pollution. There are, however, not many studies made although some drastic cases have shown the pollution threat and damaging potential. The report finally identifies the gaps in understanding of the mangrove ecosystem and the impact of human activities, lists pr iority research needs on national basis as well as for international - regional - cooperation. -
