Seeding of macrozoobenthos

Post Image

Few days ago we collected and added several thousand macroozoobenthic organisms from the Felderbacht into the experimental channels. This additional “seeding” step is important, as not all organisms enter the channels via the natural drift from the stream. By the extensive sampling of invertebrates in the river and randomised distribution into all 64 channels, we […]

Experiment has started

We have finished the experimental setup and since last Saturday (8.3.) the experiment is now running. Over the course of the next 3 weeks, organisms from the natural drift of the small stream, the Felderbach, will colonise our experimental channels. After the initial colonisation phase, we will test for the impact of different anthropogenic stressors […]

Experimental setup day 2 and 3

Post Image

Over the past two days we have continued with our work on the experimental setup. Picture 1: We drilled 64 holes in the wooden planks, so the water can leave the channels. Picture 2: Substrate for the mesocosms was taken directly from the river and dried on a plane. Picture 3: With a wooden construction […]
