This study analyzed the fatty acids composition and their profile qualitatively quantitatively of nine abundant macroalgal specimens collecting from Egyptian coasts. GC mass analysis identified 23 types, including 13 saturated (SFA) 10 monounsaturated (MUSFA). SFA dominated with 78%, while MUFAs had 22%, UFAs were negligible at 0.01%. MUSFA oleic acid (omega-9) was present in all species except...

Fatty acids (FAs) are the main components of lipids in corals. We examined FAs profiles from five symbiotic coral species belonging to different genera (Acropora, Pavona, Turbinaria, Favites, and Platygyra) four families (Acroporidae, Agariciidae, Dendrophyllidae, Faviidae). separated symbionts host tissue investigate interaction FA between tissue. After separation, we used profiles, particular...

Brown algae comprise up to 2000 species with wide dissemination in temperate zones. A comprehensive untargeted metabolic profiling guided by molecular networking of three uninvestigated Red-Sea-derived brown algae, namely Sirophysalis trinodis, Polycladia myrica, and Turbinaria triquetra, led the identification over 115 metabolites categorized as glycerolipids, fatty acids, sterol lipids, sphin...

Many temperate reefs are experiencing a shift towards greater abundance of tropical species in response to marine heatwaves and long-term ocean warming worldwide. Baseline data for coral communities growing high-latitude is required better understand ecosystem changes over time. In this study, we explore spatial temporal trends the distribution from 1999 2019 at 118 reef sites within five parks...

Evidence has shown that individually feeding or reduced light can mitigate the negative effects of elevated temperature on coral physiology. We aimed to evaluate if simultaneous low and would mitigate, minimize, exacerbate physiology carbon budgets. Pocillopora damicornis, Stylophora pistillata, Turbinaria reniformis were grown for 28 days under a fully factorial experiment including two seawat...
