Multigene phylogenetics of Sargassum (Phaeophyceae) revealed low molecular diversity in contrast to high morphological variability in the NE Atlantic Ocean

Journal of Phycology, Volume 60, Issue 6, Page 1528-1556, December 2024.
Abstract Sargassum species play a key role in habitat formation in tropical and subtropical regions; however, species identification has been hampered by the phenological plasticity exhibited in response to environmental conditions and life history. Molecular phylogenetics has challenged taxa circumscriptions and proven critical in delimiting species ...

Multigene phylogeny of the southern bull-kelp genus Durvillaea (Phaeophyceae: Fucales)

Molecular Phylogenetics and Evolution, 2010
Durvillaea (southern bull-kelp) is an economically and ecologically important brown algal genus that dominates many exposed, rocky coasts in the cold-temperate Southern Hemisphere. Of its five currently-recognized species, four are non-buoyant and restricted to the south-western Pacific, whereas one is both buoyant and widely distributed.

Long‐Term Stability of Marine Forests Facing Moderate Gradual Warming in a Remote Biodiversity Hotspot

Diversity and Distributions, Volume 30, Issue 11, November 2024.
ABSTRACT Aim Ocean warming and marine heatwaves are rapidly reconfiguring the composition of seaweed forests—the world's largest coastal vegetated biome. Seaweed forest responses to climate change in remote locations, which constitute the majority of the forest biome, remain however poorly quantified.

Progress and future directions for seaweed holobiont research

New Phytologist, Volume 244, Issue 2, Page 364-376, October 2024.
Summary In the marine environment, seaweeds (i.e. marine macroalgae) provide a wide range of ecological services and economic benefits. Like land plants, seaweeds do not provide these services in isolation, rather they rely on their associated microbial communities, which together with the host form the seaweed holobiont.

Structure and diversity patterns of coralligenous cliffs across three ecoregions in the Central‐Western Mediterranean Sea

Diversity and Distributions, Volume 30, Issue 9, September 2024.
Abstract Aim Coralligenous reefs are the main marine bioconstructions in terms of spatial distribution within the Mediterranean basin. Two distinct reef morphologies can be distinguished based on the surface and topographical features of the seafloor: cliffs developing vertical slopes and banks found on gently steep or horizontal bottoms. Despite their

Thermal refugia reinforce macroalgal resilience against climate change in the southeastern Bay of Biscay

Global Change Biology, Volume 30, Issue 8, August 2024.
Understanding how marine ecosystems respond to global warming is crucial for their protection. We studied subtidal macroalgal communities in the southeastern Bay of Biscay for over 30 years. By estimating the thermal traits of hundreds of species, we analyzed how temperature influenced community dynamics.

A revision of the genus Sargassum (Fucales, Phaeophyceae) in South Africa

South African Journal of Botany, 2015
Abstract A total of 27 different Sargassum epithets are listed in the literature for South Africa. The main aim of our study was to revise this species list using newly collected specimens in order to provide a reliable and illustrated tool for the identification of South African Sargassum .
