“…In the studied seaweeds by Kumari in 2011, the green algae Ulva rigida and Ulva reticulata had the highest proportion of oleic acid, which is considered as a characteristic of the Chlorophyta. However, the inheritance of the DHA production by members of Chlorophyta is not yet understood (Kumari et al, 2013b). This is what has been observed in several species of Ulva, namely, Ulva linza, Ulva fasciata, and U. rigida , Lola lactula (Chakraborty and Santra, 2008), and in C. rupestris harvested in winter (Stabili et al, 2014).…”

“…It seems that TL content varies mainly depending on environmental factors such as depth, light intensity, water temperature, nutrients, pH, and salinity (Guschina and Harwood, 2006). Seasonal variations have been evaluated and were reviewed by Kumari et al (2013b). Seasonal variations have been evaluated and were reviewed by Kumari et al (2013b).…”

Abstract:The aim of this study was a combined and multifaceted characterization (morphological, molecular, lipid, pigment, and ecological data) of a Lemanea (freshwater red alga) population from the south-eastern Alps, exploring its adaptive strategies to the montane habitat, (turbulent, very-cold glacial stream with extremely low-conductivity). Although the thalli were small (only up to 1 cm), the morphology was within the current circumscription of Lemanea fluviatilis. The molecular data placed this population within a clade of specimens identified as L. fluviatilis and L. fucina. This L. fluviatilis population was determined to possess lipid classes, especially phosphatidylcholine and monogalactosyldiacylglycerol with high unsaturation index (UI) and long acyl chains, which are typical adaptations for maintaining adequate membrane fluidity and consequently all the metabolic processes associated to the plasma membrane. The carotenoids profile revealed that, besides α /β-carotene, there are significant amounts of zeaxanthin and lutein. This study further demonstrated that red algae are a rich source of important food web w-3 fatty acids and may play an important role in the diets of grazers. L. fluviatilis is reported from one of the highest elevations (2,170 m a.s.l.) known for the genus Lemanea and this species. This study confirms the presence of L. fluviatilis in a cold, unpolluted, turbulent stream and this type of stream may be its preferred habitat.

“…Furthermore, nitrogen starvation also results in a reduction of chloroplasts [20,57] with a subsequent reduction in the associated membrane lipids [57] and therefore possible net reductions of total lipids. In green algae specifically, the production of starch, as the major energy storage product, also competes with TAG for the carbon precursor [58,59] and the production of starch can be favoured over TAG under nitrogen depletion [57]. These factors can therefore result in overall net decreases in the content of TFA under nitrogen depletion as occurred in D. tenuissima.…”
