Phycology

Phycology (from Ancient Greek φῦκος (phûkos) 'seaweed', and -λογία (-logía) 'study of') is the scientific study of algae. Also known as algology, phycology is a branch of life science.

Algae are important as primary producers in aquatic ecosystems. Most algae are eukaryotic, photosynthetic organisms that live in a wet environment. They are distinguished from the higher plants by a lack of true roots, stems or leaves. They do not produce flowers. Many species are single-celled and microscopic (including phytoplankton and other microalgae); many others are multicellular to one degree or another, some of these growing to large size (for example, seaweeds such as kelp and Sargassum).

Phycology includes the study of prokaryotic forms known as blue-green algae or cyanobacteria. A number of microscopic algae also occur as symbionts in lichens.

Phycologists typically focus on either freshwater or ocean algae, and further within those areas, either diatoms or soft algae.

History of phycology edit

While both the ancient Greeks and Romans knew of algae, and the ancient Chinese[1] even cultivated certain varieties as food, the scientific study of algae began in the late 18th century with the description and naming of Fucus maximus (now Ecklonia maxima) in 1757 by Pehr Osbeck. This was followed by the descriptive work of scholars such as Dawson Turner and Carl Adolph Agardh, but it was not until later in the 19th century that efforts were made by J.V. Lamouroux and William Henry Harvey to create significant groupings within the algae. Harvey has been called "the father of modern phycology"[2] in part for his division of the algae into four major divisions based upon their pigmentation.

It was in the late 19th and early 20th century, that phycology became a recognized field of its own. Men such as Friedrich Traugott Kützing continued the descriptive work. In Japan, beginning in 1889, Kintarô Okamura not only provided detailed descriptions of Japanese coastal algae, he also provided comprehensive analysis of their distribution.[3] Although R. K. Greville published his Algae Britannicae as early as 1830, it was not until 1902 with the publication of A Catalogue of the British Marine Algae[4] by Edward Arthur Lionel Batters that the systematic correlation of records, extensive distribution mapping and the development of identification keys began in earnest. In 1899-1900, Anna Weber-Van Bosse, a Dutch Phycologist travelled on the Siboga expedition and later in 1904, published The Corallinaceae of the Siboga-expedition.[5]

As early as 1803 Jean Pierre Étienne Vaucher had published on the isogamy (sexual conjugation) in the algae, but it was in the early 20th century that reproduction and development began to be extensively studied. The 1935 and 1945 comprehensive volumes of Felix Eugen Fritsch consolidated what was then known about the morphology and reproduction of the algae. This was followed in the 1950s by the development of area checklists, led by Mary Parke with her 1931 Manx Algae and followed in 1953 by her "A preliminary check-list of British marine algae"[6] Although Lily Newton's 1931 Handbook[7] provided the first identification key for the algae of the British Isles, it was the 1960s before the development of such keys became routine. The 1980s with the new emphasis on ecology[8] saw increased study of algal communities, and the place of algae in larger plant communities, and provided an additional tool for explaining geographical variation.[9][10]

The continent with the richest diversity of seaweeds is Australia, which has 2,000 species.[11]
