A protocol of environmental investigation, using GLOBE protocols

We present an example of a research dealing with urban streams, i.e., exploring the scale and possible consequences of urban impacts on ecology of aquatic ecosystems. We link urban ecology topic with the problem of endangered water resources, and use urban streams as model habitats to explore ecological themes (and concepts) in natural science and biology school classes. Besides, students meet important ecological concepts, including the concept of „urban stream syndrome“. Our presentation can serve as a model for short- and/or long-term ecological survey of urban streams close to school/student environment. It includes the investigation of ecological status of urban streams through monitoring: (i) water quality (physical-chemical properties of water) ; (ii) the composition of aquatic fauna, which forms the basis of feeding chains in aquatic ecosystems (benthic macroinvertebrates and periphytic organisms) ; (iii) dynamics of transport (downstream drift) of organisms in urban watercourses. In the implementation of the activities, it is encouraged to use some of the GLOBE protocols.
