Abstract
Organisationsübersicht am Beispiel von Epiphanes senta. Rein bisexuelle Vermehrung bei Seison annulatus (Seisonidea) mit Darstellung der Genitalorgane beider Geschlechter. Heterogonie der Monogononta bei Brachionus urceolaris und bei der viviparen Asplanchna girodi: Weibchen, Eitypen, Zwergmännchen, Begattung. Philodina citrina als Beispiel der parthenogenetischen Entwicklung der Bdelloidea.
First, the organization of a rotifer (Epiphanes senta) is shown. The Seisonidea (Seison annulatus) reproduce by fertilized eggs, only. In the Monogononta (Brachionus urceolaris, Asplanchna girodi), both parthenogenesis and bisexual reproduction occur: amictic females, amictic egs; mictic females, hatching and organization of dwarf males, copulation, dormant eggs. In the Bdelloidea (Philodina citrina) males are absent. Reproduction is exclusively parthenogenesis.
