Conservation genomics of a critically endangered brown seaweed
Journal of Phycology, 2021Seaweeds provide valuable ecosystem services, but many are undergoing global decline due to climate and anthropogenic stressors. The brown macroalga, Nereia lophocladia (hereafter called Nereia), is among only a handful of seaweeds globally to be listed as critically endangered and is only described from two known locations, but there exists little ...

Nature Methods
Brown seaweeds are multicellular eukaryotes that have been evolving independently of animals and plants for more than a billion years. The filamentous brown alga Ectocarpus has been used as a model to understand the biology of these enigmatic organisms and to shed light on a range of major questions, from the molecular basis of complex developmental ...

Carbohydrates of the brown seaweed lessonia nigrescens
Phytochemistry, 1983Abstract Stipes plus haptera and fronds were extracted separately. Crystalline mannitol and two oligouronic acids were separated from the ethanolic extracts of both parts of the weed. ‘Fucans’ were present in all the sequential aqueous, acidic and alkaline extracts.
