Unusual physiology of scale-less carp, Gymnocypris przewalskii, in Lake Qinghai: a high altitude alkaline saline lake.

The scale-less carp (Gymnocypris przewalskii) inhabits Lake Qinghai located on the Qinghai-Tibet plateau (elevation, 3200 m) in western China. The lake waters are alkaline (pH 9.4, titratable alkalinity=30 mmol l(-1)), Mg(2+)-rich (18.7 mmol l(-1)), Ca(2+)-poor (0.30 mmol l(-1)) and saline (9 per thousand ). These fish make annual spawning migrations into freshwater rivers. We investigated the ...

Vertical flux regulation and plankton composition in a simple ecological system: snapshots from the small marine Lake Rogoznica (Croatia)

Vertical flux regulation was investigated in the small, shallow, marine and partly anoxic Lake Rogoznica (eastern coast of the Adriatic Sea) by studying plankton composition, zooplankton fecal pellet (FP) production and vertical carbon flux. The lake is naturally eutrophicated with high nutrient and particulate organic carbon (POC) concentrations and relatively low species diversity. However, t...

Limnological conditions in Subglacial Lake Vostok, Antarctica

Subglacial Lake Vostok is located ,4 km beneath the surface of the East Antarctic Ice Sheet and has been isolated from the atmosphere for .15 million yr. Concerns for environmental protection have prevented direct sampling of the lake water thus far. However, an ice core has been retrieved from above the lake in which the bottom ,85 m represents lake water that has accreted (i.e., frozen) to th...

Observations of a deep-mixing event in Crater Lake, Oregon

We present observations of the evolution of a deep-mixing event in a deep, temperate lake. The observations were obtained from thermistors mounted on a long-term mooring in the lake. The event seems to have originated near 150-m depth and resulted in a plume or layer of cold water from the upper half of the lake that descended to the lake bottom (590 m) over a 3-d period. Net mixing associated ...

Effect of Halophyte Patches on Some Soil Properties of a Saline Rangeland Around Urmia Lake, Iran

Plants may induce small-scale heterogeneity in soil nutrients, forming fertile islands. However, this process may depend on plant spices, plant developmental stages and habitat conditions. Vegetation cover in arid and semi-arid regions is mostly in the form of plant patches and bare soil of inter-patch areas, this form of vegetation cover can be useful to study plants impact on soil to get appl...
