Knowledge of abiotic limnological factors is important to monitor changes caused by humans, and to explain the structure and dynamics of populations and communities in a variety of inland water ecosystems. In this study, we used a long term data-set (eight years) collected in 10 habitats with different features (river channels, and connected and isolated lakes) to describe the spatial and tempo...

Environmental variability in space and time is a primary mechanism allowing species that share resources to coexist. Fluctuating conditions are a double edged sword for diversity, either promoting coexistence through temporal niche partitioning or excluding species by stochastic extinctions. The net effect of environmental variation on diversity is largely unknown. We examined the association b...

Reservoirs exhibit gradients in conditions and resources along the transition from lotic to lentic habitat that may be important to bluegill ecology. The lotic-lentic gradient can be partitioned into three functional zones: the riverine, transitional, and lacustrine zones. We measured catch frequency and length of bluegills (Lepomis macrochirus) captured along the periphery of these areas (i.e....

The paper describes work in progress the application of process-oriented modeling to situation assessment within a research project in limnology. In the field study, some 50 lakes in Southern Germany are monitored in order to explore and document the changes in the distribution of a particular aquatic plant, Najas marina, and understand their preconditions. The ultimate objective is using this ...

Interrelations bctwecn drainage area, lake area, length, mean breadth, mean depth, and maximum depth arc examined in 2G2 rock basins and 137 basins lying in or dammed by glacial drift. The effect of lake dimensions upon the time taken for complete water replacement is calculated, and an illustration is given of the influence of lake urea and mean depth upon the tcmpcrature of surface and bottom...

The ice-cover period in lakes is increasingly recognized for its distinct combination of physical and biological phenomena ecological relevance. Knowledge gaps exist where research areas hydrodynamics, biogeochemistry biology intersect. For example, density-driven circulation under ice coincides with an expansion the anoxic zone, but abiotic biotic controls on oxygen depletion have not been dis...
