How ?

The general principle is simple: we create a global network of interested stream ecologists, we all spend a few time and little expenses for a simple and exciting experiment. Pooled together, these individual experiments will generate a unique, compelling and timely dataset to address the objective above. Furthermore, it may trigger follow-up activities well beyond the present approach. In 3 words: united we stand.

The requirement of this project is to mobilize stream ecologists interested in IRES to work on multiple IRES: ideally, ~1 000, minimally > 100. A simple, cheap and time-efficient experiment carried out almost simultaneously and across a large number of IRES will provide a unique and outstanding dataset to explore. The rough quality of each single experiment, as well as the low amount of data individually generated will be largely compensated by the large number of IRES and the high consistency of the protocols used.

The first phase of the project will consist in creating this international network of volunteered stream ecologists. The second phase will be to collect environmental data and samples (coarse particulate organic matter –CPOM- on dry riverbeds, biofilms/algal mats and river sediments) on individual IRES in a consistent and simple procedure (see below). The third phase will be to ship a subsample of the collected material, to IRSTEA where they will be consistently processed. The fourth and last phase will be to analyze the data and write the associated paper(s).
