“…Seagrasses constitute an important source of food for several marine organisms; important nutritional compounds include proteins, carbohydrates or lipids and fatty acids (review in Kim et al, 2021). Despite the ecological importance of seagrasses as a food source to higher tropic levels, only few studies have explicitly assessed the role of environmental changes on their nutritional value.…”

Seasonal Acclimation Modulates the Impacts of Simulated Warming and Light Reduction on Temperate Seagrass Productivity and Biochemical Composition

et al. 2021

Increases in seawater temperature and reduction in light quality have emerged as some of the most important threats to marine coastal communities including seagrass ecosystems. Temperate seagrasses, including Zostera marina, typically have pronounced seasonal cycles which modulate seagrass growth, physiology and reproductive effort. These marked temporal patterns can affect experimental seagrass responses to climate change effects depending on the seasons of the year in which the experiments are conducted. This study aimed at evaluating how seasonal acclimatization modulates productivity and biochemical responses of Zostera marina to experimental warming and irradiance reduction. Seagrass shoots were exposed to different temperatures (6, 12, 16, 20, and 24°C), combined with high (180 μmol photons m–2 s–1) and low (60 μmol photons m–2 s–1) light conditions across four seasons (spring: April, summer: July, and autumn: November 2015, and winter: January 2016). Plants exhibited similar temperature growth rates between 16 and 20°C; at 24°C, a drastic reduction in growth was observed; this was more accentuated in colder months and under low irradiance conditions. Higher leaf growth rates occurred in winter while the largest rhizomes were reached in experiments conducted in spring and summer. Increases in temperature induced a significant reduction in polyunsaturated fatty acids (PUFA), particularly omega-3 (n-3 PUFA). Our results highlight that temperate seagrass populations currently living under temperature limitation will be favored by future increases in sea surface temperature in terms of leaf and rhizome productivity. Together with results from this study on Z. marina from a temperate region, a wider review of the reported impacts of experimental warming indicates the likely reduction in some compounds of nutritional importance for higher trophic levels in seagrass leaves. Our results further demonstrate that data derived from laboratory-based studies investigating environmental stress on seagrass growth and acclimation, and their subsequent interpretation, are strongly influenced by seasonality and in situ conditions that precede any experimental exposure.

“…Research on secondary metabolites is frequently moving in the direction of bioactivity-focused medication discovery. Numerous intricate and unique chemical entities are produced as a result of research into the marine ecology (Kim et al, 2021). Considering that seagrass has a high concentration of antioxidants such polyphenols, terpenoids, flavonoids, tannins and saponins.…”

Seagrasses are the flowering plant found in marine ecosystem. It has many bioactive compounds with various applications including pharmaceutical and nutraceutical. The present study has been aimed to evaluate the nutritional composition and antioxidant potentials of the Seagrass Syringodium isoetifolium. The Seagrass exhibits significant amounts of biochemical and phytochemical compositions. In in-vitro antioxidant, DPPH, ABTS and Hydroxyl radical scavenging assay showed that S. isoetifolium was an excellent scavenger for free radicals. The results suggest that the Seagrass S. isoetifolium may be used as a very good renewable marine resource for potential biomedical applications in future

“…The affiliations that materialize between marine plants and microorganisms also have industrial applications for the discovery of useful bioactive compounds, including in medicine and nutraceuticals [ 35 ]. There has also been a growing interest in developing marine plants ( Syringodium filiforme and Enhalus acoroides ) as a new potential food source for human consumption or culinary use [ 36 , 37 ].…”

The Vibrionaceae encompasses a cosmopolitan group that is mostly aquatic and possesses tremendous metabolic and genetic diversity. Given the importance of this taxon, it deserves continued and deeper research in a multitude of areas. This review outlines emerging topics of interest within the Vibrionaceae. Moreover, previously understudied research areas are highlighted that merit further exploration, including affiliations with marine plants (seagrasses), microbial predators, intracellular niches, and resistance to heavy metal toxicity. Agarases, phototrophy, phage shock protein response, and microbial experimental evolution are also fields discussed. The squid–Vibrio symbiosis is a stellar model system, which can be a useful guiding light on deeper expeditions and voyages traversing these “seas of interest”. Where appropriate, the squid–Vibrio mutualism is mentioned in how it has or could facilitate the illumination of these various subjects. Additional research is warranted on the topics specified herein, since they have critical relevance for biomedical science, pharmaceuticals, and health care. There are also practical applications in agriculture, zymology, food science, and culinary use. The tractability of microbial experimental evolution is explained. Examples are given of how microbial selection studies can be used to examine the roles of chance, contingency, and determinism (natural selection) in shaping Earth’s natural history.
