Karstic rivers are hydrogeologically conditioned to have spatial and seasonal changes in their discharge <ref name="multiple">MEYER, A., E.I. MEYER & C. MEYER 2003. Lotic communities of two small temporary karstic stream systems (East Westphalia, Germany) along a longitudinal gradient of hydrological intermittency. Limnologica 33 (4): 271. </ref>. In the high plateau of Paderborn (Paderborner Hochfläche), the left tributary of the Lippe, Alme, itself and some of its tributaries are temporary rivers due to fluctuations of groundwater levels (Hungerbrunnen).

Projects:

• Preliminary sampling at the Menne

# of sampling	Date
First sampling	22.05.2020

Fourth sampling	14.09.2021

Sampling of 3 karst rivers

In the framework of the Programme for the promotion of excellent early career researchers

Aim

Compare microscopy diatom identification with molecular samples (rbcL and 18S V4) for a further project application.

Rivers to be sampled:

Sampling sites
