Última Sexual and asexual reproduction in Didemnum rodriguesi (Ascidiacea, Didemnidae) Iheringia, Sér. Zool. Ritzmann,Nicole F.; Rocha,Rosana M. da; Roper,James J.. Sexual and asexual reproduction and associated population dynamics were investigated in the colonial ascidian Didemnum rodriguesi Rocha & Monniot, 1993 (Didemnidae) in southern Brazil. Investment in sexual (production of new individuals) and asexual (colony growth) reproduction was compared between seasons. Permanently marked quadrats were repeatedly photographed to measure changes in colonies. Eggs and larvae were counted monthly in collected colonies. This species alternates seasonally between sexual (summer) and asexual (winter) reproduction. In summer, colonies were smaller, brooded eggs and larvae and recruitment rates were greater, while in winter, colony size was larger and eggs and larvae were absent. There is a relationship between... Tipo: Info:eu-repo/semantics/article Palavras-chave: Reproductive investment; Sexual reproduction; Fragmentation; Tunicates.
