Hypotheses regarding ecology and biogeography of diatoms in temporary streams in each aquatic state.
The Lippe - Alme System
The Menne is a tributary of the Altenau, which is a tributary to the Alme, the Lippe tributary which flows into the Rhine.
The Menne was studied by Meyer et al. in 2003, looking into the effect of karstic drought on macroinvertebrates. The aim of our study is to characterize the diatom communities in ephemeral and inundated locations along this stream.
