The study included 144 fishes in Lake of 16 Tishreen Dam for detecting the infection with parasitic Protozoans, and determine distribution rate. Fishes were collected randomly once a month, during period from 22/12/2011 until 22/12/2012. Collected samples belonged to following species: Cyprinus carpio L., Varicorhinus damascinus, Garra rufa, Tilapia zillii, Liza abu. T. zillii was most prevalen...

Harmful algal blooms are increasingly common in aquatic ecosystems and have been linked to runoff from agricultural land. This study investigated the internal nutrient (i.e., phosphorus (P) and nitrogen (N)) dynamics of a eutrophic reservoir in the Midwestern United States to constrain the potential for sedimentary nutrients to stimulate harmful algal blooms. The spatial distribution of nutrien...

Few studies have focused on the post-eruption evolution of maar craters and associated lake level changes, although breaching crater rim poses mass-flow flood hazards long after initial eruption. Lake Pavin is a in French Massif central formed by an eruption c. 6700 years ago. The perched edge glacially-shaped valley overlooks surrounding subdued landscape. breached to north overflow channel, s...

• Authors focus on An. arabiensis as the major malaria vector in the area. However, no data is provided regarding other potential malaria vectors that could play an important role on malaria transmission at the Gilgel-Gibe dam site, as An. funestus and An. nili species complex. Were these species collected during the two years entomological survey at all? In the conclusions, it is stated that t...

Atatürk Dam Lake, which was established on the Euphrates River for agricultural irrigation and electricity production, is largest dam lake in Turkey. Many fish species, are primary food source humans, live lake. Therefore, possible pollution this will adversely affect not only but also human health. For purpose, study, lead, cadmium, chromium, iron, zinc, copper levels were measured liver, gill...

Among Village, most potential to attract tourists. Some advantages include scenery, fresh air, easy acc...

The ubiquitous lakes across China’s Yangtze Plain (YP) are indispensable freshwater resources sustaining ecosystems and socioeconomics for nearly half a billion people. Our recent survey revealed a widespread net decline in the total YP lake inundation area during 2000–2011 (a cumulative decrease of 10%), yet its mechanism remained contentious. Here we uncover the impacts of climate variability...

The delineation of lateral and vertical gradients of organic contaminants in lakes is hampered by low concentrationsand nondetection of many organic compounds in water. Passive samplers (semipermeable membrane devices [SPMDs] and polar organic chemical integrative samplers [POCIS]) are well suited for assessing gradients because they can detect synthetic organic compounds (SOCs) at pg L(-1) con...

Pymatuning Lake, located on the Pennsylvania/Ohio border, is noted for the large numbers of bread-eating carp that frequent the Linesville Causeway "carp bowl" from May to November. Carp were trapped in 1952 and 1984 at the carp bowl, tagged, and relocated varying distances away from the bowl in Sanctuary, Middle, and Lower lakes. Carp traversed the return distances of up to 9 km in less than 4...
