Bodenwerder, Weser

In October 2012 I took a sample from the bank of the river Weser, close to the old railroad bridge, in the town of Bodenwerder, in Central Germany. The sample came from a large stone just beneath the water level. At home I made some Moist-Chamber-Mounts, which resulted in some beautiful and unexpected amoeboids:

  • Paramphitrema lemanense
  • Cyphoderia calceolus
  • Cyphoderia laevis
  • Cochliopodium granulatum
  • Leptophrys sp.
  • Polychaos dubium
  • Rhizamoeba caerulea
  • Thecamoeba striata
  • Penardeugenia spec., probably new species
  • Limnofila spp.
  • Microgromia sp.
  • Lecythium granulatus
  • Lithocolla spec.
  • Microcometes paludosa
  • Acanthocystis aculeata
  • Nuclearia flavocapsulata
  • Chlamydaster laciniatus
  • Centropyxis ecornis
  • Difflugia varians
  • Euglypha acanthophora
