Karacaören-II Dam Lake is located on Aksu Stream within the borders of Burdur. The lake planned to be a drinking water supply for Antalya in near future. Some scientific studies carried out recent years stated that suffers from eutrophication problem due pressures basin.
 This study examined relationships between selected quality parameters (BOD5, DO, pH, NH4-N, NO2-N, NO3-N, TKN, TN, o-PO...

Wild riverine fishes are known to rely on burst swimming to traverse hydraulically challenging reaches, and yet there has been little investigation as to whether swimming anaerobically in areas of high flow can lead to delayed mortality. Using acoustic accelerometer transmitters, we estimated the anaerobic activity of anadromous adult sockeye salmon (Oncorhynchus nerka) in the tailrace of a div...

Azolla nilotica does not occur in Egypt today, reaching as far north as central Sudan. Its spores have been recorded in sediment cores from the Nile Delta near Manzala Lake up to ca. 550 AD. As part of the CASSARINA Project on recent changes in ecosystems of North African lakes, short sediment cores, covering up to the last two centuries, were taken from the open water of the large Delta lagoon...

Cyanobacterial blooms and hepatotoxic microcystins (MCs) usually occur in summer, constituting a sanitary and environmental problem in Salto Grande Dam, Argentina. Water sports and recreational activities take place in summer in this lake. We reported an acute case of cyanobacterial poisoning in Salto Grande dam, Argentina, which occurred in January 2007. Accidentally, a young man was immersed ...

This paper aims at assessing the concentrations of heavy metals and the isotopic composition of lead 210Pb in different fractions of sediment produced in the watershed that makes up the Mãe d'água dam and thus characterizing the distribution of metals along the sedimentary column and inferencing in the urbanization of the same process. Sample collection was carried out in June 2014; eight sedim...

Hydrologic regime plays a major role in structuring biotic diversity within river ecosystems by controlling key habitat conditions within the river channel and floodplain. Daily flow records from seven hydrological stations and the range of variability approach were utilized to investigate the variability and spatial pattern of the hydrologic alterations induced by the construction of the Three...

A total of 94 bacteria, associated with wild Achanthobrama marmid (Heckel, 1843) in Sir Dam lake of Turkey identified. Subsequently selected isolates were characterized and identified to the genus level The 94 members of Enterobacteriaceae were isolated in the gills and intestines, and among the isolates, E. coli were represented at a rate of 55%, Shigella spp. at a rate of 21%, Salmonella spp....

Elizabeth (Beth) Jones reveled in the excitement of scientific discovery and fostered curiosity with steadfast determination. With high standards and rigor, she applied a firm but gentle hand to cultivate the curiosity of generations of students. Inquisitiveness about science and the workings of nature was threaded through her life, unabated, from early childhood. Born in Seattle, Beth spent he...
