Spatial Distribution Characteristics and Influencing Factors of Weishan Lake

Characteristics and Factors Influencing the Hysteresis of Water Area–Stage Curves for Poyang Lake

Flood dynamics of large lake floodplain systems are typically complex. This paper analyses the characteristics and factors that influence the hysteresis of water area–stage curves for Poyang Lake, the largest freshwater lake in China characterized by complex geomorphology and upstream–downstream exchange conditions. For this purpose, a two-dimensional hydrodynamic model (EFDC) based on seven sc...

Temporal and spatial distribution of extreme precipitation indices over the lake Urmia Basin, Iran

The ecological factors influencing morphological characteristics of Alburnusatr opatenae

The present study investigated morph metric characteristics of two populations of Alburnusatr opatenae in two rivers on north western Iran. In addition, the role of important ecological factors influencing morph metric features was studied. Ninety three specimens were collected from the Siminehrood (39) and Zarinerood (54) Rivers using electrocution. The specimens were photographed using a digi...

Factors influencing the spatial distribution of zooplankton and fish in Loch Ness, UK

1. The vertical and horizontal distribution of phytoplankton, zooplankton and fish in Loch Ness, Scotland, were monitored during one day-time and one night-time survey in July 1992. The vertical samples were collected at a site located at the northern end of the loch and the horizontal samples along a longitudinal transect. 2. The vertical distribution surveys demonstrated that the phytoplankto...

Factors influencing the cultivability of lake water bacteria.

Counting bacteria in natural water samples by cultivation yields only low recovery efficiencies (ca. 1%), compared to total counts obtained after 4,6-diamidino-2-phenylindol (DAPI) staining. In order to optimize the cultivation of heterotrophic planktonic bacteria from Lake Constance (Germany), selected parameters of the medium composition were modified. The most important factor was the concen...
