Water quality and water use efficiency are the two most important management issues. Engineering measures to enhance water use efficiency have not produced the desired outcome due to poor water quality caused by eutrophication of reservoirs resulting from the input of nutrients in water primarily by animal feces. Consequently water in the reservoirs is under-utilized and groundwater faces the prospect ...

These "troglomorphic characters" are expressed in the populations of Garra barreimiae from the Al Hoota Cave and nearby Hoti Pit in Northern Oman. Surface morphotypes of this cyprinid species are common throughout the distribution area. Very rarely individuals with intermediate phenotypes can be found. In the present study, potential gene flow between cave and surface populations was tested and population structure within five sampling sites was assessed. Overall, 213 individuals were genotyped at 18 microsatellite loci. We found that the cave populations have lower genetic diversity and are clearly isolated from the surface populations, which seem to be sporadically in contact with each other. The results indicate a recent genetic bottleneck in the cave populations. Thus, it can be assumed that during climatic changes the connection between cave and surface water bodies...
