摘要:This study was conducted to evaluate the ecosystem diversity and succession around Gaber-Oun Lake-Libya. The Lake is an inland at halassohaline water body located in the Sahara, south of Libya. The lake has an area of about 0.06 km2 and a maximum depth of 9.2 m, and it lies 450 m above sea level. The results showed that air & water temperature, dissolved oxygen and salinity readings were uniform through the lake profile and sampling times. Data also reflected high organic content and low concentrations of dissolved salt in southern direction. Gaber-Oun lake presented a meso-thermal profile varying from 19℃ at the surface to 31℃ at 2.5 m depth; more detailed studies will be necessary to establish the thermal characteristics of the lake. The lake has a high salinity which varies between 90 and 160 g/L. Humidity, nutrients and organic matter, may play significant role in the environmental stress which may lead to succession, through decomposition of organic matter and microbial activities to circulate nutrients. The vegetation diversity around the lake included 8 families divided in to 13 genus.
