Cystoseira algae (Fucaceae): update on their chemical entities and biological activities

Tetrahedron: Asymmetry, 2017
Abstract Cystoseira (Sargassaceae) is a genus of marine brown algae composed of about 40 species, which is distributed along the Eastern Atlantic and Mediterranean coasts. The biological potential of the Cystoseira genus has been investigated and several activities have been reported.

Shift happens: trailing edge contraction associated with recent warming trends threatens a distinct genetic lineage in the marine macroalga Fucus vesiculosus [PDF]

, 2013
Significant effects of recent global climate change have already been observed in a variety of ecosystems, with evidence for shifts in species ranges, but rarely have such consequences been related to the changes in the species genetic pool.

A critical review of analytical methods used for the chemical characterisation and quantification of phlorotannin compounds in brown seaweeds

Phytochemical Analysis, Volume 30, Issue 6, Page 587-599, November/December 2019., 2019
Abstract Introduction Phlorotannins, the phenolic compounds found in brown seaweeds, are a unique and diverse class of compounds showing a huge potential for food and pharmaceutical applications. Objective This review will give an account of the colorimetric assays used and a discussion of their quantitative and qualitative analytical shortcomings.

Using multiple tracers and directly accounting for trophic modification improves dietary mixing‐model performance

Ecosphere, Volume 7, Issue 8, August 2016., 2016
Abstract Stable isotope (SI) mixing models are one of the most common approaches used to infer resource pathways in consumers. However, SI‐based analyses are often underdetermined, and consumer SI fractionation is often unknown. The use of fatty acid (FA) biomarkers in mixing models offers an alternative approach that can resolve the underdetermined ...

Connectivity and Population Structure in a Marginal Sea—A Review

Diversity and Distributions, Volume 31, Issue 7, July 2025.
ABSTRACT Aim The current biodiversity crisis calls for conservation measures that limit or reduce the negative human impact on key habitats and vulnerable wild populations. To effectively protect biodiversity at all levels, including intra‐specific diversity, conservation measures should, ideally, be aligned with the connectivity and genetic structure ...

Distribution, morphology, and genetic affinities of dwarf embedded Fucus populations from the Northwest Atlantic Ocean [PDF]

, 2006
Dwarf embedded Fucus populations in the Northwest Atlantic Ocean are restricted to the upper intertidal zone in sandy salt marsh environments; they lack holdfasts and are from attached parental populations of F. spiralis or F. spiralis x F.

Evolution and diversification within the intertidal brown macroalgae Fucus spiralis/F. vesiculosus species complex in the North Atlantic [PDF]

, 2014
We examined 733 individuals of Fucusspiralis from 21 locations and 1093 Fucusvesiculosus individuals from 37 locations throughout their northern hemisphere ranges using nuclear and mitochondrial markers. Three genetic entities of F.

Improved phylogeny of brown algae Cystoseira (Fucales) from the Atlantic- Mediterranean region based on mitochondrial sequences [PDF]

, 2019
Cystoseira is a common brown algal genus widely distributed throughout the Atlantic and Mediterranean regions whose taxonomical assignment of specimens is often hampered by intra- and interspecific morphological variability.
