We compared the population growth patterns of 5 species of the rotifer genus Lecane [(L. quadridentata (Ehrenberg, 1830), L. comuta (Muller, 1786), L. papuana (Murray, 1913), L. unguitata (Fadeev, 1925) and L. pyriformis (Daday, 1905)] ranging in adult average body size from 30 to 140 microm. All species were cultured under laboratory conditions for 25-30 days using the green alga Scenedesmus a...

Mercuric chloride (HgCl2) is a common heavy-metal pollutant widely used in commercial products and industry, but its excessive use uncontrolled discharge have caused great harm to aquatic environments human health. To research the mechanisms of HgCl2 toxicity organisms, this study cultured green alga Scenedesmus quadricauda gradient concentrations (0, 0.1, 0.3, 0.5, 0.7, 0.9 mg/L) for 9 days. T...

Natural carotenoids from green microalgae exhibit beneficial effects in treating health-related diseases, primarily due to their antioxidant capacity. Therefore, carotenoid-producing were isolated and characterized aqueous samples KwaZulu-Natal (South Africa) under photoautotrophic conditions. Three isolates comprehensively using light electron microscopy. In addition, the growth of three selec...

Determining how temperature alters direct predation and indirect trophic cascade effects will be crucial in understanding how global climate change affects community structure and stability. While we are starting to comprehend the effects of warming on individual trophic interactions and underlying mechanisms, effects of warming on multilevel food webs are mostly unknown. This study sought to e...

The ultrastructure of dictyosomes in Scenedesmus acuminatus was studied by the freeze-substitution method. The cisternal membranes of dictyosomes clearly exhibited three-layered structures. Electron-dense particles were visible on or in the proximal cisternal membranes. The upper and lower membranes of the distal cisternae were in close contact with each other at the cisternal centre. The elect...
