Coastal countries have traditionally relied on the existing marine resources (e.g., fishing, food, transport, recreation, and tourism) as well tried to support new economic endeavors (ocean energy, desalination for water supply, seabed mining). Modern societies lifestyle resulted in an increased demand dietary diversity, better health well-being, biomedicines, natural cosmeceuticals, environmental conservation, sustainable energy sources. These societal needs stimulated interest of...
ABSTRACT This paper focuses on the marine foundation eelgrass species, Zostera marina , along a gradient from northern Baltic Sea to north‐east Atlantic. vast region supports minimum of 1480 km 2 (maximum >2100 ), which corresponds more than four times previously quantified area in Western Europe. Eelgrass meadows low salinity support highest diversity (4–6 spp.) angiosperms overall, but productivity is (<2 g dw m ‐2 d ‐1 ) and are isolated genetically impoverished. Higher areas...
A synthesis of phenotypic and quantitative genomic traits is provided for bacteria archaea, in the form a scripted, reproducible workflow that standardizes merges 26 sources. The resulting unified dataset covers 14 traits, 5 4 environmental characteristics approximately 170,000 strain-level 15,000 species-aggregated records. It spans all habitats including soils, marine fresh waters sediments, host-associated thermal. Trait data can find use clarifying major dimensions ecological strategy...
Marine organisms produce a vast diversity of metabolites with biological activities useful for humans, e.g. cytotoxic, antioxidant, anti-microbial, insecticidal, herbicidal, anticancer, pro-osteogenic and pro-regenerative, analgesic, anti-inflammatory, anti-coagulant, cholesterol-lowering, nutritional, photoprotective, horticultural or other beneficial properties. These could help satisfy the increasing demand alternative sources nutraceuticals, pharmaceuticals, cosmeceuticals, food, feed,...
Abstract Aquaculture has been one of the fastest‐growing food production systems sectors for over three decades. With its growth, demand alternative, cheaper and high‐quality feed ingredients is also increasing. Innovation investments on providing new functional alternatives have yielded several viable alternative raw materials. Considering all current ingredients, their circular adaption in aquafeed manufacturing industry clearly utmost importance to achieve sustainable aquaculture near...
1. This study provides evidence for the existence of general intrinsic patterns controlling maximum growth rate photosynthetic organisms, based on a compilation data from more than 120 reports, species ranging unicellular algae to trees and thick-leaved desert plants. 2. We used thickness nutrient concentration tissue scale differences in among plants, demonstrated importance these plant traits regulating rates particular groups. 3. The declined with increasing structures increased nitrogen...

SUMMARY 1. We analysed photosynthetic rates and inorganic carbon use of thirty‐five vascular macrophyte species collected submerged in eight nutrient‐ CO 2 ‐rich Danish lowland streams. The were classified four groups as mainly terrestrial, homophyllous heterophyllous amphibious truly submerged. These represent plant differently adapted to life water. 2. Photosynthetic measured water increased the gradual transition from through species. Species normally contact with air submergence by...
Kelps, seaweeds and seagrasses provide important ecosystem services in coastal areas, loss of these macrophytes is a global concern. Recent surveys have documented severe declines populations the dominant kelp species, S accharina latissima , along south coast Norway. . cold‐temperate increasing seawater temperature has been suggested as one major causes decline. Several studies shown that can acclimate to wide range temperatures. However, local adaptations may render extrapolation existing...

The microalgal pigment phycoerythrin (PE) is of commercial interest as natural colorant in food and cosmetics, well fluoroprobes for laboratory analysis. Several methods extraction quantification PE are available but they comprise typically various buffers, repetitive freeze-thaw cycles liquid nitrogen, making procedures more complicated. A simple method from cryptophytes described using standard materials equipment. cryptophyte cells on the filters were disrupted at −80 °C added phosphate...

The size dependency of maximum growth rates was investigated in cyanobacteria and green algae (Chlorophyta). Both unicellular colony-forming species were included the study. Significant allometric relationships found between rate for both algae. size-dependent could be described by same scaling exponent algae, but only unicells evinced rates—there no relationship colony colonial forms It is concluded that form represents an evolutionary adaptation to escape negative effects growth, while...
The purpose of this study was to clarify effects anthocyanins on photosynthesis and photoinhibition in green red leaves Oxalis triangularis. Gas analysis indicated that plants had the highest apparent quantum yield for CO2 assimilation [0.051 vs. 0.031 μmol(CO2) μmol-1(photon)] maximum [10.07 7.24 m-2 s-1], while fluorescence measurements PSII [0.200 0.143 μmol(e-) ETRmax [66.27 44.34 s-1].
