Climate change is driving range contractions and local population extinctions across the globe. When this affects ecosystem engineers the vacant niches left behind are likely to alter the wider ecosystem unless a similar species can fulfil them.Here, we explore the stress physiology of two coexisting kelps undergoing opposing range shifts in the Northeast Atlantic and discuss what differences i...

Alginates being depolymerized during their alkaline extraction, reducing extraction time could help producing higher rheological quality alginates. The purpose of the present work is to study fresh Laminaria digitata destructuration during alkaline extraction and its link to extraction kinetics. Both alginate extraction yield and mean diameter of algae particles were followed for different valu...

Seaweed has long been used in the Japanese and Chinese diet. In 600 B.C., Sze Teu wrote in China, "Some algae are a delicacy fit for the most honored guests, even for the King himself." Some 21 species are used in everyday cooking in Japan, six of them since the eighth century. Seaweed accounts for some 10% of the Japanese diet and seaweed consumption reached an average of 3.5 kg per household ...

Diospyros kaki folium, Laminaria japonica thallus and Undaria pinnatifida thallus have been used traditionally in Korea to promote maternal health. The scavenging activity against DPPH (1,1-diphenyl-2-picrylhydrazyl) radicals of the methanol extracts of these plants were investigated. The extract of D. kaki was found to be the most potent, with an IC(50) value of 0.11 mg/ml.

Objective. Development of an effective method for preparing the cervix in pregnant women with a tendency to overmaturity against background lack biological readiness childbirth, as well reducing time soft birth canal childbirth order conduct subsequent labor excitation.
 Material and methods. The patients were divided into 3 groups depending on childbirth: 1st group (n = 50) only laminaria...

Intertidal macroalgae Fucus and Laminaria experience seasonally fluctuating inorganic N supply. This study examined the effects of long-term N deprivation, recovery following N resupply, and effects of elevated ammonium and nitrate exposure on N acquisition in intertidal algae using manipulations of N supply in tank culture. Over 15 weeks of N deprivation, internal N and nitrate reductase activ...

Kelp (Laminaria digitata) uses iodide as a unique inorganic antioxidant to protect its surface and apoplastic space against reactive oxygen species such ozone, hydrogen peroxide superoxide, with implications for atmospheric marine chemistry well regional climatic processes. If kelp is covered by seawater, this results in leaching into surrounding sea water. In study, the influence of kelps Lami...
