Evaluation of the Bioenergetic Potential of Marine Macroalgae in Anaerobic Digestion Systems

CLEAN – Soil, Air, Water, Volume 54, Issue 4, April 2026.
ABSTRACT This study evaluated the production of biogas by anaerobic digestion, using three groups of marine macroalgae: Chlorophytes (green), Phaeophytes (brown), Rhodophytes (red), and their mixture (GRB). The objective was to investigate how the composition of each group influences the production of biogas and methane, as well as the use of digestate

Microhabitat Patchiness Structures Benthic Biodiversity in the Western Antarctic Peninsula

Ecology and Evolution, Volume 16, Issue 4, April 2026.
Shallow benthic communities of the West Antarctic Peninsula cannot be considered uniform habitats but rather mosaics of microhabitats, each characterised by distinct macroalgal communities and associated fauna. Regional biodiversity and patterns are shaped by the number and types of microhabitats.

tRNA functional signatures classify plastids as late-branching cyanobacteria. [PDF]

, 2019
BackgroundEukaryotes acquired the trait of oxygenic photosynthesis through endosymbiosis of the cyanobacterial progenitor of plastid organelles. Despite recent advances in the phylogenomics of Cyanobacteria, the phylogenetic root of plastids remains ...

Red Algae (Rhodophyta) from the Coast of Madagascar: Preliminary Bioactivity Studies and Isolation of Natural Products

Marine Drugs, 2015
Several species of red algae (Rhodophyta) from the coastal regions of Madagascar have been investigated for their natural products. The most abundant compound was cholesterol (5) in combination with a series of oxidized congeners.

Direct and indirect effects of Gracilaria vermiculophylla on native Fucus vesiculosus [PDF]

, 2013
The perennial red macroalga Gracilaria vermiculophylla (Ohmi) Papenfuss has recently been introduced to the Baltic Sea and is a potential competitor to Fucus vesiculosus, the most common native perennial alga in large parts of the Baltic Sea.

Examining Short Temporal Changes in Intertidal Macroalgal Microbiomes at 'Ewa Beach, O'Ahu, Hawai'i: Some Hosts Varied While Others Remained Stable

Environmental Microbiology Reports, Volume 18, Issue 2, April 2026.
We examined microbiome variability in seven macroalgal species over 5 days at an intertidal bench in 'Ewa Beach, O'ahu, Hawai'i. Microbial communities of some red and brown algae fluctuated, whilst green algae remained stable. Temporal patterns varied by species and potentially by differences in intertidal positioning and exposure to environmental ...

How endo- is endo-?: surface sterilization of delicate samples: a Bryopsis (Bryopsidales, Chlorophyta) case study [PDF]

, 2010
In the search for endosymbiotic bacteria, elimination of ectosymbionts is a key point of attention. Commonly, the surface of the host itself or the symbiotic structures are sterilized with aggressive substances such as chlorine or mercury derivatives ...

Coralline algae in a naturally acidified ecosystem persist by maintaining control of skeletal mineralogy and size [PDF]

, 2016
To understand the effects of ocean acidification (OA) on marine calcifiers, the trade-offs among different sublethal responses within individual species and the emergent effects of these trade-offs must be determined in an ecosystem setting.
