Microbial mats in dinosaur ichnocoenoses

Sedimentology, EarlyView.
ABSTRACT Until now, the significance of microbial mats in preservation of dinosaur tracks and in reconstructing the palaeoenvironment in which dinosaurs roamed was rarely studied. Dinosaur tracks are commonly found close to ancient aquatic bodies where moist sediment had once allowed footstep registration.

Alternative equilibria in shallow lakes

Trends in Ecology & Evolution, 1993
The turbidity of lakes is generally considered to be a smooth function of their nutrient status. However, recent results suggest that over a range of nutrient concentrations, shallow lakes can have two alternative equilibria: a clear state dominated by aquatic vegetation, and a turbid state characterized by high algal biomass.

TBT Causes Regime Shift in Shallow Lakes

Environmental Science & Technology, 2006
Tributyltin (TBT) is an organotin compound used since the early 1960s as a biocide in boat antifouling paints. Its use has been linked to a host of negative effects in marine ecosystems including malformations and imposex in Mollusca and acute toxicity in many other aquatic animals.

Shallow urban lakes: a challenge for lake management

Hydrobiologia, 1999
Urban lakes are very different from other lakes: they are shallow, highly artificial and often hypertrophic yet more people come into contact with them than rural, natural lakes. Our knowledge of their ecology and management is poor. This paper describes a project under the EU Life programme to understand and ecologically manage the most important ...
