This paper conducts an assessment on the social-ecological resilience of China’s Dongting Lake (and its three sections – East, West and South Dongting Lake) in relation to the perturbations of the Three Gorges Dam using a set of resilience-based indicators. Expert scoring is applied to identify the different states of the lake and their resilience levels. Based on equal weighting for all indica...

1. Daphnia pulex and Daphnia middendorffiana are commonly found in the Toolik Lake region of arctic Alaska. These two species are very similar morphologically, although their natural distributions differ markedly: D. pulex is restricted to shallow ponds, while D. middendorffiana is widely distributed and found in a variety of ponds and lakes. We compared the reproductive capabilities of D. pule...

The concentrations of heavy metals (Ag, Cd, Co, Cu, Ni, Pb, Zn) were analyzed in muscle, skin and liver of Anatolian Khramulya, Capoeta tinca (Heckel, 1843) from Çamlıgöze Dam Lake located at Central Anatolian region of Turkey. The heavy metal analysis of samples was carried out by using a flame atomic absorption spectrophotometer. Ag, Cd, Co, Pb and Zn were found in all of the examined tissues...

Lake Oroville is a large artificial lake created by the construction of a 235-mhigh earth dam on the Feather River, California, near the city of Oroville. Its storage capacity is about 4.4 × 109 m 3, and its maximum depth is about 200 m. There was no significant increase in seismic activity in the lake region following impoundment of the dam late in 1967 until the occurrence of many small seism...

Construction of the Three Gorges Dam across the Yangtze River will substantially change the ecology of the Dongting Lake in southern China. In addition, the Chinese Central and Hunan Provinces' governmental authorities have instigated a Return Land to Lake Program that will extend the Dongting Lake surface area from the current 2,681 km2 to 4,350 km2. The previous construction of embankments an...

nature has always proven that it is able to overcome its problems. however, humanmanipulation has led to environmental degradations. the dryness of a thousand-year urmia lake(a brine water lake in iran) is an example of environmental degradation that happened due tosuccessive droughts and construction of dams on the basin of this lake. this study examinesmethods for the revival of urmia lake by...

the zerebar lake is a shallow freshwater lake located in the northwestern iran. the lake is surrounded by three human activities: agriculture, tourism and dam. the present study aimed to investigate (1) which human activity has the greatest impact on eutrophication of the zerebar lake (2) if phytoplankton communities, as the indicator, are correlated with the human activities. water samples wer...

OBJECTIVE The aim of this study was identification of the parasites of the common carp from Tahtalı Dam Lake. METHODS The fish were transported live to the laboratory. They were investigated for ectoparasites and endoparasites. The parasite specimens were fixed and identified. RESULTS During the study, 47 common carp were caught monthly and 3 species of metazoan parasites were found: Dactyl...
