Experiment on edge sensitivity of Fuligo septica.
The plasmodial slime mould Fuligo septica was inoculated on a larger number of prepared petri dishes. The dishes were filled with non-nutrient Agar agar 1,5%. With a scalpel geometries were cut into the surface under sterile conditions:
- square (a1=15mm, a2=30mm, a3=50mm)
- circle (diameter d1=30mm, d2=50mm, d3=70mm)
- triangle (a1=15mm, a2=30mm, a3=50mm)
Then the slime mould was inoculated either at the center inside the cutted geometry or outside near the edge of a geometric form.
The hypothesis was, if Fuligo would alig to the cutted edges and this be able to be controlled in its foreaging behaviour.
