This paper illustrates the malleable boundaries that define nature. Personal construct theory is employed to examine the apparent contradiction of the human/nature binary posed by landscapes generated by domesticated agriculture and physical and biological processes. Specifically, the paper reports on how tourists to the Kimberley region of Australia discriminate between their perception of hum...

Mujib and Haidan rivers were sampled in July 2011 to identify fish populations in the riverine system, and to investigate the impact caused by the existence of two dams. Fishes were sampled by electofishing gear through 14 sampling points distributed along the two rivers. The Mujib Dam lake was sampled by gillnets. A total of 2,854 fish specimen were caught during the study of which most consis...

This study was carried out in Apa Dam Lake between January 2001 and December 2001. Characteristics of sexuality status, age groups, growth and reproduction as well as condition factor of Cyprinus carpio (L. 1758) population, which inhabits this dam lake and is of economic importance, was investigated. The age composition of Cyprinus carpio samples were determined to have ranged from I to VIII. ...

The Zn, Cu, As, Cd, Hg and Pb levels of the popular species (Silurus triostegus, Acanthobrama marmid, Aspius vorax, Capoeta trutta, Carasobarbus luteus, Chalcalburnus mossulens and Cyprinus carpio) of Ataturk Dam Lake (Euphrates, Turkey) were studied to estimate the risk of human consumption and pollution of Euphrates River which is important for Turkey, Syria and Iraq. Trace metal amounts diff...

Crayfish (Astacus leptodactylus Eschscholtz, 1823) is the native crayfish species in Turkey. It was exported regularly to Western Europe. In this study, bioaccumulation and temporal trends of some trace elements (arsenic: As, cadmium: Cd, copper: Cu, mercury: Hg, lead: Pb, and zinc: Zn) in edible abdomen muscle of crayfish from Keban Dam Lake (Elazığ, Turkey) were investigated for the 2006-2012...

Lake Matahina, an 8 km long hydroelectric storage reservoir, is a small (2.5 km), 50 m deep, warm monomictic, gorge-type lake whose internal circulation is controlled by the inflowing Rangitaiki River which drains a greywacke and acid volcanic catchment. Three major proximal to distal subenvironments are defined for the lake on the basis of surficial sediment character and dominant depositional...

This is the first study on diet of Great Cormorant wintering in Algeria. It carried out Beni Haroun, largest dam lake country, north-east The trophic menu Phalacrocorax carboin this based four species fish; Abramis bramas, Carassius carassius, Barbus barbus and Cyprinus carpio. However, carassius represent two most important Cormorant’s diet. total consumed biomass 155,364.18 g, average contain...

Abstract Landslide dam outburst floods have a significant impact on landform evolution in high mountainous areas. Historic landslide dams the Yigong River, southeastern Tibet, generated two superfloods > 10 5 m 3 /s 1902 and 2000 AD. One of slackwater deposits, which was newly found immediately downstream historic dams, has been dated to 7 ka BP. The one-dimensional backwater stepwise method...

300 MW Baspa II is India’s largest private hydroelectric facility, located at the Baspa River which is an important left-hand tributary to the Sutlej River in the NW Himalaya (India). In this valley the Sangla palaeo-lake has been dammed around 8200 yr BP behind a rock-avalanche dam and Baspa II is located exactly on top of this palaeo-lake. This special location represents a very rare possibil...

The aim of this study was to compare some biochemical blood parameters of rainbow trout (Oncorhynchus mykiss) living in running or still waters. Some biochemical parameters of rainbow trout were examined, and the results were evaluated between sampling locations and according to seasonal changes. Healthy adult rainbow trout were caught from six different locations on the Bahçelik Dam Lake and t...
