Special Issue Information

Dear Colleagues,

One of the world's largest sustainable marine resources is seaweed, which provides numerous benefits on both ecological and human levels through various ecosystem services. Over recent decades, significant progress has been made in the knowledge and use of seaweeds as feed, food, fertilizer, sustainable materials, and energy sources, which should certainly be part of the strategies that humankind should consider in these areas. Seaweed, by reducing cattle methane, replacing fossil plastic, and storing a significant amount of carbon, shows great potential in the pursuit of global food security and fighting climate change. Seaweed farming is the fastest growing aquaculture sector benefiting communities and the environment. Innovative seaweed cultivation techniques, micro-propagation and breeding tools, biomass processing optimizations coupled with robotic, advanced sensing, and monitoring techniques are delivering improved productivity and can better ensure the sustainable development of the seaweed farming and processing industry. The acceleration of climate change, reduction in conventional access to food, materials, and energy put the use of seaweeds in an important position regarding basic knowledge and effective production. This information is not only important for scientific advancement, but also for diverse seaweed industries, as well as local decision-makers.

In this Special Issue entitled Seaweed Biology: Focusing on Food, Materials and Bioenergy, papers will be accepted from a broad scope of interdisciplinary research on seaweed taxonomy, biology, cultivation, seaweeds for food, sustainable material, and energy viewpoints, from basic molecular biology to industrial application. Original research papers, methods, reviews, and perspectives are welcome for submission.

Green algae blooms of the genus Ulva are occurring globally and are primarily attributed to anthropogenic factors. At Los Tubos beach in Algarrobo Bay along the central Chilean coast, there have been blooms of these algae that persist almost year-round over the past 20 years, leading to environmental, economic, and social issues that affect the local government and communities. The objective of this study was to characterize the species that form these green tides based on a combination of ecological, morpho-anatomical, and molecular information. For this purpose, seasonal surveys of beached algal fronds were conducted between 2021 and 2022. Subsequently, the sampled algae were analyzed morphologically and phylogenetically using the molecular markers ITS1 and tufA, allowing for the identification of at least five taxa. Of these five taxa, three (U. stenophylloides, U. uncialis, U. australis) have laminar, foliose, and distromatic morphology, while the other two (U. compressa, U. aragoensis) have tubular, filamentous, and monostromatic fronds. Intertidal surveys showed that U. stenophylloides showed the highest relative coverage throughout the seasons and all intertidal levels, followed by U. uncialis. Therefore, we can establish that the green tides on the coast of Algarrobo in Chile are multispecific, with differences in relative abundance during different seasons and across the intertidal zone, opening opportunities for diverse future studies, ranging from ecology to algal biotechnology.
