Temporal stability and spatial patterns of genetic diversity in populations of the climate-vulnerable fucoid Scytothalia dorycarpa. [PDF]

J Phycol
Abstract Climate change is driving the loss of genetic diversity, potentially limiting species' capacity to adapt to environmental change. Detecting changes in genetic diversity requires replicated temporal data, which is lacking for most species. Here, we combined contemporary and historical specimens of the climate‐vulnerable fucoid Scytothalia ...

Fucoidans of Brown Algae: Comparison of Sulfated Polysaccharides from Fucus vesiculosus and Ascophyllum nodosum

Marine Drugs, 2022
Preparations of sulfated polysaccharides obtained from brown algae are known as fucoidans. These biopolymers have attracted considerable attention due to many biological activities which may find practical applications.

Modeling macroalgal forest distribution at Mediterranean scale : present status, drivers of changes and insights for conservation and management [PDF]

, 2020
Macroalgal forests are one of the most productive and valuable marine ecosystems, but yet strongly exposed to fragmentation and loss. Detailed large-scale information on their distribution is largely lacking, hindering conservation initiatives.

Reproductive Allocation of the Habitat-Forming Intertidal Macroalga <i>Ascophyllum nodosum</i> Decreases at Its Northern Distribution Edge. [PDF]

Ecol Evol
Ascophyllum nodosum is predicted to expand its northern distribution in the sub‐Arctic, but its reproduction has never been assessed at such high latitudes. This study analyzed the reproductive allocation and phenology of A. nodosum at its northern distribution limit in Greenland in comparison with populations across its geographical distribution and ...

Changes in the Structure of the Bacterial Community Associated With <i>Ericaria amentacea</i> Blades Under Disturbed Conditions. [PDF]

Plant Environ Interact
ABSTRACT The macroalgae of the Cystoseira sensu lato complex host a great epiphytic bacterial community that significantly guarantees several important physiological processes, especially in case of disturbance. However, no direct evidence of relevant changes in the quali‐quantitative composition of these communities under anthropic disturbance is ...

When chemistry meets taxonomy: Studying glycolipidic chemomarkers in pelagic Sargassum spp. (Phaeophyceae) using molecular networking. [PDF]

J Phycol
Abstract To chemically differentiate the three pelagic Sargassum morphotypes co‐occurring in floating rafts and drifting across the Atlantic Ocean before stranding on West African, Caribbean, and Atlantic Mexican coastlines, we conducted an investigation of their metabolomic profiles.

Microbe-assisted seedling crop improvement by a seaweed extract to address fucalean forest restoration

Frontiers in Marine Science, 2023
In the Mediterranean, Cystoseira sensu lato (s.l.) (Phaeophyceae) forests have sharply declined and restoration measures are needed to compensate for the loss.

Response of Early Life-Stages of Forest-Forming Seaweeds From Warm-Edge and Central Populations to Marine Heatwaves. [PDF]

Ecol Evol
Marine heatwaves (MHWs) pose a threat to global marine forests, with the effects of warming potentially being even greater on early life stages, which are often understudied. We evaluated the responses of Phyllospora comosa—one of the most crucial forest‐forming seaweeds in South‐eastern Australia—early life stages from warm‐edge and central ...

Massive decline of Cystoseira abies-marina forests in Gran Canaria Island (Canary Islands, eastern Atlantic)

Scientia Marina, 2017
Brown macroalgae within the genus Cystoseira are some of the most relevant “ecosystem-engineers” found throughout the Mediterranean and the adjacent Atlantic coasts.

Diversity and temporal dynamics of the epiphytic bacterial communities associated with the canopy-forming seaweed Cystoseira cornpressa (Esper) Gerloff and Nizamuddin [PDF]

, 2016
Canopy-forming seaweed species of the genus Cystoseira form diverse and productive habitats along temperate rocky coasts of the Mediterranean Sea. Despite numerous studies on the rich macrofauna and flora associated with Cystoseira spp., there is little ...
