Re-isolation and revaluation of boundaries of Thecamoeba terricola Greeff, 1886 (Amoebozoa, Discosea, Thecamoebida), with description of Thecamoeba vicaria n. sp.

We studied a large species of Thecamoeba found in a glass dish with soaked moss and obtained 18s rRNA gene sequence of this organism. Morphologically, the strain was most similar to T. terricola sensu Page, but had significant differences in cell size and nuclear morphology.

Maternal Transcripts of Hox Genes Are Found in Oocytes of (Annelida, Nereididae).

Hox genes are some of the best studied developmental control genes. In the overwhelming majority of bilateral animals, these genes are sequentially activated along the main body axis during the establishment of the ground plane, i.e.
