Asexual reproduction of Nausithoe aurea (Cnidaria, Scyphozoa, Coronatae) induced by sterile polystyrene dishes

Asexual Reproduction of Nausithoe Aurea (cnidaria, Scyphozoa, Coronatae) Induced by Sterile Polystyrene Dishes

Discovery and redescription of type material of Nausithoe simplex (Kirkpatrick, 1890), comb. nov. (Cnidaria: Scyphozoa: Coronatae: Nausithoidae) from the North Atlantic

With discovery and examination of type specimens in the Natural History Museum, London, UK, we reassign Stephanoscyphistoma simplex (Kirkpatrick, 1890) to the genus Nausithoe Kölliker, 1853, as Nausithoe simplex, comb. nov., and designate a lectotype for the species. Use of morphometric measurements is considered important in coronate systematics, but key features also include the unique whorl ...

Environmental control of asexual reproduction and somatic growth of Aurelia spp. (Cnidaria, Scyphozoa) polyps from the Adriatic Sea

Polyps of two moon jellyfish species, Aurelia coerulea and A. relicta, from two Adriatic Sea coastal habitats were incubated under multiple combinations of temperature (14, 21°C), salinity (24, 37 ppt) and food regime (9.3, 18.6, 27.9 μg C ind-1 week-1) to comparatively assess how these factors may influence major asexual reproduction processes in the two species. Both species exhibited a share...

SHORT COMMUNICATION Salinity effects on asexual reproduction of Carybdea sp. (Cnidaria: Cubozoa)

Medusa production in cubozoans may be associated with reduced-salinity waters. Asexual reproduction of Carybdea sp. differed at different salinities. The metamorphosis of Carybdea sp. polyps into medusae was accelerated at low salinity (32), while more polyps were budded from the original polyp at the highest salinity (38), probably due to prolonged metamorphosis. High-nutrient river discharge ...

Molecular evidence for cryptic species of Aurelia aurita (Cnidaria, Scyphozoa).

Morphological taxonomy suggests that marine faunas are species poor compared to terrestrial and freshwater faunas (1). This dichotomy has been attributed to the unique potential of marine plankters for distant dispersal across homogenous oceans with few barriers to gene flow (2). The relative scarcity of opportunities for allopatric divergence has resulted in depauperate marine faunas character...
