286 Roadside drying of rhodophytes
on the island of Terceira (Azores).
Rapid growth of other macroalgal species in the estuary, such as the rhodophytes
Moreover, during the entire experiment, neither a large cover of encrusting calcified rhodophytes
nor bare rock was detected around the seagrass patches, indicating that there were no signs of overgrazing by P.
Dumontiae and other rhodophytes
have been confirmed in vivo and in vitro to inhibit growth of several viruses, notably herpes simplex I and II, and HIV.
Diatoms were the most abundant and diverse algal organisms (359 taxa), followed by chlorophytes (121), Cyanobacteria (42), euglenophytes (31), xanthophytes (14), chrysophytes (12), rhodophytes
(6), dinophytes (6), and cryptophytes (3).
This is what happens in the rhodophytes
and cyanobacteria, which use the nitrogen of their phycobilin pigments for cell growth if there are no external sources of nitrogen compounds.
This is with the addition of eight chlorophytes, one chrysophyte (a macroscopic tubicolus diatom species), two phaeophytes and five rhodophytes
Specifically, tropical LBFs that are important for carbonate production host dinoflagellates (some soritids), diatoms (calcarinids, amphistiginids, alveolinids, and nummulitids), and rhodophytes
(some soritids; see table 1 in Ziegler and Uthicke, 2011).
On the coasts of Brittany and Monterey, the upper circumlittoral consists of mixed populations of corallinaceous algae (Mesophyllum, Lithothamnium, Lithophyllum), laminar rhodophytes
(Rhodymenia, Fryeella, Phycodrys), and suspensivorous animals (sponges like Axinella, alcyonarians like Alcyonium, or Paralcyonium), but they do not form communities as complex as those in the Mediterranean.
Consequences of light limitation for carbon acquisition in three rhodophytes
Two other phototrophic organisms were reported from skeletons of live corals, the filamentous cyanobacterium Plectonema terebrans and conchocelis stages of bangiacean rhodophytes
