This species can be found attached to hard bottoms like reef and rocky surfaces anywhere in between 3–100 ft. [2] This alga grows better with high light intensity but it is still capable of growing with low light leves.
Volvox is a polyphyletic genus of chlorophyte green algae in the family Volvocaceae. Volvox species form spherical colonies of up to 50,000 cells, and for this reason they are sometimes called globe algae. They live in a variety of freshwater habitats, and were first reported by Antonie van Leeuwenhoek in 1700.
Various polymers can be created from algae, which can be especially useful in the creation of bioplastics. These include hybrid plastics, cellulose-based plastics, poly-lactic acid, and bio-polyethylene. [133] Several companies have begun to produce algae polymers commercially, including for use in flip-flops [134] and in surf boards. [135]
In 1837 it was found in Church Bay in County Antrim, [10] but has not been found there since. Codium adhaerens C.Agardh; Codium bursa C.Agardh - has been found in Mulroy Bay in County Donegal in 1977 (specimen in the Ulster Museum) and 1988. There is an old record of it from "near Belfast" between 1793 and 1810.
Marine algae can be divided into six groups: green, red and brown algae, euglenophytes, dinoflagellates and diatoms. Dinoflagellates and diatoms are important components of marine algae and have their own sections below. Euglenophytes are a phylum of unicellular flagellates with only a few marine members. Not all algae are microscopic.
Alaria is most commonly found in far northern waters of the Pacific and Atlantic oceans, with the greatest variety of species concentrated in the north Pacific. More specifically, it has been found on the coasts of England , Ireland , Scotland , Iceland , Greenland , Denmark , Norway , Japan, China, Korea, Canada , and the United States .
Ulvaria obscura is a common marine algae, typically identified in algal blooms referred to as "Green Tides". [3] [4] The species is distinct in its ability to produce the neurotransmitter dopamine as a herbivore defense mechanism.
Scenedesmus is one of the most common freshwater algae genera; however, the extremely diverse morphologies found within species make identification difficult. [4] While most species are found across the world, certain species exist only in local populations such as S. intermedius and S. serratus which are found in New Zealand.
