TLDR
Air and SCUBA diving observations revealed numerous, dense concentrations of free living, branched, nongeniculate coralline algae (rhodoliths) at depths of 3–12 m in Bahia Concepcion, B.C.S., Mexico, suggesting that broad scale and depth distribution of rhodolith beds within the bay are controlled by water motion and sedimentation.About:

Calcified macroalgae - critical to coastal ecosystems and vulnerable to change: a review
TL;DR: Research is urgently needed on all aspects of the taxonomy, biology and functional ecology of calcifying macroalgae, including being key to a range of invertebrate recruitment processes, functioning as autogenic ecosystem engineers through provision of three-dimensional habitat structure and contributing critical structural strength in coral reef ecosystems.

Rhodolith bed diversity in the Gulf of California: the importance of rhodolith structure and consequences of disturbance
TL;DR: Data suggest that reducing the population size structure, structural complexity and cover of living rhodoliths could decrease species richness and abundance, and increased anthropogenic disturbance from trawling, anchoring and changes in water quality can directly impact the bed community through substrate alteration.

Environmental tolerances of free-living coralline algae (maerl): implications for European marine conservation
TL;DR: Maerl was not as susceptible as previously assumed to extremes of salinity, temperature and heavy metal pollution, but burial, especially in fine or anoxic sediments, was lethal or caused significant stress, and sedimentation resulting from disruption to tidal flow is the main anthropogenic hazard.

Coralline algae (Rhodophyta) in a changing world: integrating ecological, physiological, and geochemical responses to global change.
TL;DR: What is known about coralline algal ecology and physiology is summarized, providing context to understand their responses to global climate change and critical gaps in understanding are indicated.

TL;DR: The European Commission's Habitats Directive mandates the conservation management of two of the main European maerl-forming species, Phymatolithon calcareum and Lithothamnion corallioides.

Pebbles in the Lower Colorado River, Texas a Study in Particle Morphogenesis
Edmund D. Sneed,Robert L. Folk +1 more
TL;DR: In this paper, a triangular diagram is proposed for analysis of the equant versus disklike versus rodlike aspect of particles, here termed "form," and it was shown that even within this narrow range, particle size has a greater effect on sphericity and form than 200 miles of fluvial tra...

TL;DR: In this paper, the authors present a review of the Calcification Processes in Algae and Cyanobacteria and classify them into three major groups: calcified cyanobacteria, calcified algae, and calcified nannofossils.

Crustose Coralline Algae: A Re-evaluation in the Geological Sciences
Walter H. Adey,Ian G. Macintyre +1 more
TL;DR: The crustose coralline algae are well known in shallow tropical waters as reef frame-builders and sediment producers as mentioned in this paper, but this knowledge in recent decades has been largely ignored by geologists and marine scientists in general.

Growth-forms in non-geniculate coralline red algae (Corallinales, Rhodophyta)
TL;DR: It is shown that an intergrading network of growth-forms with 10 focal points is present: unconsolidated, encrusting, warty, lumpy, fruticose, discoid, layered, foliose, ribbon-like and arborescent.

Form and Internal Structure of Recent Algal Nodules (Rhodolites) from Bermuda: A Reply
TL;DR: The growth forms and internal structure of living coralline algal nodules (here termed rhodolites) from a shallow Bermuda bay contain a surprisingly sensitive record of the frequency of their movement by wave action.
