Thermal vulnerability of the Levantine endemic and endangered habitat-forming macroalga, Gongolaria rayssiae: implications for reef carbon

Frontiers in Marine Science, 2022
Ocean warming is a major threat to marine ecosystems, especially to species with a narrow thermal niche width and narrow biogeographic distribution, like some habitat-forming seaweeds.

THE SYSTEMATIC POSITION OF THE FUCALES [PDF]

New Phytologist, 1939
T HE Fucales are probably the most widely distributed and the most abundant of all the brown algae. They have certainly reached the highest level of morphological and anatomical differentiation, yet their systematic position remains one of apparent isolation, and it has recently been claimed that they have been derived independently of all the other ...

Biodiversity of Sargassum (Fucales, Sargassaceae) from Eastern Samar (Philippines) inferred from nuclear ribosomal internal transcribed spacer (ITS) sequence data

Applied Phycology, 2022
Sargassum is the most diverse genus in the brown algal order Fucales, which is an ecologically important primary producer in marine ecosystems. The Philippines has about 73 species of Sargassum identified based solely on morphology, representing 18% of ...

Communities and Attachment Networks Associated with Primary, Secondary and Alternative Foundation Species; A Case Study of Stressed and Disturbed Stands of Southern Bull Kelp

Diversity, 2019
Southern bull kelps (Durvillaea spp., Fucales) are ‘primary’ foundation species that control community structures and ecosystem functions on temperate wave-exposed rocky reefs.

Algae-mediated biosynthesis of zinc oxide nanoparticles from Cystoseira crinite (Fucales; Sargassaceae) and it's antimicrobial and antioxidant activities

Egyptian Journal of Chemistry, 2021
Zinc oxide nanoparticles (ZnO-NPs) have gained attention due to their distinctive properties and applications. In the current study, we developed an eco-friendly, economical, and green route for the synthesis of ZnO-NPs using the aqueous extract of the ...

An Acetocarmine Squash Technique for the Fucales [PDF]

Nature, 1957
ACETOCARMINE techniques have only been used to a limited extent in cytological studies of the Phaeophyta, and only in examination of filamentous forms, or filamentous phases in the life-history of the larger forms. Investigations of the Fucales have relied on techniques of embedding and microtoming, followed by staining with Heidenhain's haematoxylin1 ...

Dynamic structural colour increases photosynthetic performance in the alga Ericaria selaginoides

Applied Phycology, 2021
Structural colour occurs when nanoscale structures interfere with incident light transmission and reflect particular wavelengths. The brown alga Ericaria selaginoides (Fucales, Phaeophyceae) has an opalescent photonic crystal anatomy that creates the ...

Coexistence of the reef-building coral Cladocora caespitosa and the canopy-forming alga Treptacantha ballesterosii: Description of a new Mediterranean habitat

Scientia Marina, 2020
Shallow Mediterranean rocky environments are usually dominated by macroalgae, but the stony colonial zooxan­thellate coral Cladocora caespitosa is able to build extensive banks in some particular areas.

Adaptation of the alginate production process for the brown alga Sargassum horridum (Fucales: Sargassaceae)

Ingeniería Investigación y Tecnología, 2022
The genus Sargassum is a brown alga which is abundant in México, in the Gulf of California and the Caribbean Sea. The large biomass could be used to production of alginate, a polysaccharide with properties which allow it to form a thick solution or gels ...

Too Hot to Handle: Effects of Water Temperature on the Early Life Stages of Gongolaria barbata (Fucales)

Journal of Marine Science and Engineering
Gongolaria barbata plays a crucial role as a habitat-forming Fucales species in the Mediterranean Sea, thriving in shallow, sheltered coastal regions, where it exhibits optimal growth in a temperature range of 10 to 25 °C. In the northern Adriatic Sea, a
