Identification of Carotenoids in Halimeda macroloba Reef Associated Bacteria

open access: yesIlmu Kelautan, 2016
Several carotenoid pigments which are produced by sea microorganisms are shown to function as antimicrobe compounds and potential antioxidants. Coral reefs with high levels of diverse biota facilitate Halimeda as a primary component and producer to have ...

OCCURRENCE OF TETRASPORANGIA IN Ceramium bisporum (CERAMIALES, RHODOPHYTA)

open access: yesActa Biológica Colombiana, 2014
The presence of tetrahedrally divided tatrasporangia in Ceramium bisporum Ballantine is reported for the first time. The plant was found as epiphytic on calcareous Halimeda tuna in coral reef environment in Caribbean Colombia.

Reduced sediment accumulation rate enhances early marine diagenesis of periplatform sediments

open access: yesThe Depositional Record, Volume 12, Issue 2, April 2026.
The influence of reduced sediment accumulation rate on early marine burial diagenesis was investigated in sediments collected by ODP Leg 133. Results show that low sediment accumulation rates can produce substantial and asynchronous shifts in stable carbon isotope ratios across a slope transect without the development of sedimentological indicators of ...

Diurnal fluctuations in seawater pCO2 amplify the negative effects of ocean acidification on the biotic performance of the calcifying macroalga Halimeda opuntia

open access: yesFrontiers in Marine Science, 2022
Although the adverse effects of increasing atmospheric CO2-induced ocean acidification (OA) on marine calcifying macroalgae have been widely reported, there are limited studies on how daily fluctuations in pCO2 (pH) within shallow ecosystems influence ...

Monitoring Coral Reef Metabolism Under Changing Oceans–Novel Insights From Seawater Stable Carbon Isotopes

open access: yesJournal of Geophysical Research: Biogeosciences, Volume 131, Issue 4, April 2026.
Abstract Mounting environmental stressors are driving Caribbean reefs from coral to sponge and macroalgae dominance, necessitating a need for more nuanced metrics of reef metabolism under trophic transitions. Drawing upon four seasonally replicated field campaigns to Curaçao, we reveal highly variable net ecosystem productivity (−243 ± 69 C m−2 day−1 ...

Morphological variation and haplotype diversity of Halimeda macroloba and H. opuntia (Chlorophyta: Halimedaceae) from Southern Vietnam

open access: yes, 2022
Plasticity in morphology is a common phenomenon of aquatic plants. Halimeda (Chlorophyta: Halimedaceae) is usually supersaturated with calcium carbonate and is found in tropical and subtropical regions.

Ocean acidification alters the calcareous microstructure of the green macro-alga Halimeda opuntia

open access: yes, 2015
Decreases in seawater pH and carbonate saturation state (Omega) following the continuous increase in atmospheric CO2 represent a process termed ocean acidification, which is predicted to become a main threat to marine calcifiers in the near future ...
