Only 12 species of marine algae were known until now from the Desventuradas Archipelago. A recent collection added 10 species yielding a total of six Chlorophyta, nine Phaeophyta, and seven Rhodophyta. Only one species, Padina tristromatica Levring, is endemic. More than half of the representatives are in common with the flora of the Juan Fernandez Archipelago, but only five species are also fo...

This study investigated the biological activities of five benthic marine algae collected from Northeastern Region of Brazil. The tested activities included larvicidal activity against Aedes aegypti, molluscicidal activity against Biomphalaria glabrata, and toxicity against Artemia salina. Extracts of Ulva lactuca (Chlorophyta), Padina gymnospora, Sargassum vulgare (Phaeophyta), Hypnea musciform...

An optimization procedure was applied to investigate the anticandidal property of four different Iranian seaweed extract compositions. Response Surface Methodology (RSM) with the four levels- three–factor Box–Behnken design, including Gracilaria arquata concentration (X1), Nizimudidnia zanardini concentration (X2), Cystoceria indica concentration (X3) and Padina australis concentration (X4), wa...

On dynamic coastlines, populations of protected algal species with poor dispersal might be especially vulnerable to infrequent recruitment events and local extinction. As a model, we here consider the alga Padina pavonica from largest remaining physically isolated enclaves on south coast England. A bio-physical model was used investigate likely importance propagule in maintaining populations. D...

Marine macroalgae, such as Padina boergesenii, are gaining recognition in the cosmetics industry valuable sources of natural bioactive compounds. This study aimed to investigate biochemical profile P. boergesenii and evaluate its potential a cosmetic ingredient. Fourier-transform infrared (FTIR), gas chromatography–mass spectrometry (GCMS), high-resolution liquid quadrupole time-of-flight (HRLC...
