Cross‐Depth Genetic Connectivity Supports the Role of Deep Kelp Forests as Refuge From Climate Change

open access: yesDiversity and Distributions, Volume 32, Issue 5, May 2026.
ABSTRACT Aim Ocean warming and marine heatwaves are threatening the persistence of kelp forests, but cooler, deeper reefs might act as refuges from which shallow populations can recover. This study aimed to assess the genetic connectivity, diversity, and adaptive structure of deep kelp reefs to evaluate their potential as climate refuges.

First Report of Marinomyxa spp. (Rhizaria: Endomyxa: Phytomyxea) Infection in Seagrasses Halophila beccarii and Halophila decipiens: Supporting Evidence for a Long‐Standing Symbiosis

open access: yesPlant Pathology, Volume 75, Issue 3, May–June 2026.
A survey of phytomyxid parasites in seagrasses of the genus Halophila reveals previously unrecognised diversity and a widespread presence of Marinomyxa within Halophila meadows, supporting a tight co‐evolutionary relationship between the two genera. ABSTRACT Marinomyxa is a genus of obligate intracellular parasitic protists known to infect tropical ...

Seaweed Habitats on the Shore: Characterization through Hyperspectral UAV Imagery and Field Sampling

open access: yesRemote Sensing, 2022
Intertidal macroalgal habitats are major components of temperate coastal ecosystems. Their distribution was studied using field sampling and hyperspectral remote mapping on a rocky shore of Porspoder (western Brittany, France).

The role of the epidermal physode layer in UV protection of Fucus species

open access: yesJournal of Photochemistry and Photobiology, 2023
Phlorotannins are believed to provide UV protection in brown algae. In Fucus species, phlorotannin-rich vesicles (“physodes”) form an “epidermal physode layer”, which might represent the anatomical structure responsible for UV protection.

Narrow thermal range restricts fertilization and early growth in the habitat‐forming seaweed Durvillaea potatorum (Phaeophyceae)—Implications for aquaculture and climate resilience

open access: yesJournal of Phycology, Volume 62, Issue 2, Page 556-567, April 2026.
Abstract The southern bull kelp Durvillaea potatorum is a key habitat‐forming macroalga in southeastern Australia and has been identified as a species of interest for sustainable seaweed aquaculture. However, the species is threatened by rising ocean temperatures and other anthropogenic factors. Assessing the thermal limits across different life stages

Diversity and phylogeny of Sargassum (Fucales, Phaeophyceae) in Singapore

open access: yesPhytotaxa, 2018
Sargassum species play key ecological roles on coral reefs, yet their diversity remains poorly known. Precise identification of Sargassum species, however, is improving with molecular genetic tools, though these have yet to be applied rigorously in Singapore.

Unravelling the complexity of salt marsh ‘Fucus cottonii’ forms (Phaeophyceae, Fucales) [PDF]

open access: yesEuropean Journal of Phycology, 2017
Genetic affiliation, nuclear DNA content, and gamete functioning were examined in small salt marsh Fucus from three localities in western Ireland. Individuals with small and dioecious receptacles were found at all localities, but production of germlings was only evident at Locality 1.
