Phycology, the study of algae

The name Phycom is a giveaway for those who recognise the phy from phycology, the study of algae. Phycology is a branch of life sciences and originates from Ancient Greek. The term consists of Phûkos (φῦκος), which means seaweed, and -logía, which means ‘study of’ (λογία). So it is the scientific study of algae, also known as algology; phycology is a branch of life science.

Algae are important primary producers in aquatic ecosystems. Most algae are eukaryotic, photosynthetic organisms that live in a wet environment. They are distinguished from 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. Several microscopic algae also occur as symbionts in lichens. Phycologists typically focus on either freshwater or ocean algae and, within those areas, diatoms or soft algae.

The History of Phycology

The ancient Greeks and Romans, along with the ancient Chinese, recognized algae, and some Chinese cultures even cultivated specific varieties for consumption. However, the formal scientific study of algae traces its roots to the late 18th century. It began with Pehr Osbeck’s description and naming of Fucus maximus (now Ecklonia maxima) in 1757. Subsequent scholars such as Dawson Turner and Carl Adolph Agardh furthered this descriptive work.

Notably, it wasn’t until later in the 19th century that J.V. Lamouroux and William Henry Harvey attempted to organize algae into significant groupings. Harvey, often referred to as “the father of modern phycology”, divided algae into four major divisions based on pigmentation.

In the late 19th and early 20th centuries, phycology emerged as a distinct field. Friedrich Traugott Kützing and others continued their descriptive efforts, while in Japan, Kintarô Okamura provided detailed descriptions and analyses of coastal algae in 1889.

While earlier works such as R. K. Greville’s Algae Britannicae (1830) laid some groundwork, it wasn’t until Edward Arthur Lionel Batters’ 1902 publication A Catalogue of the British Marine Algae that systematic correlation of records, extensive distribution mapping, and the development of identification keys began in earnest.

20th Century

In terms of research focus, the study of algae’s reproductive processes and development gained traction in the early 20th century. Felix Eugen Fritsch’s comprehensive volumes in 1935 and 1945 consolidated algae morphology and reproduction knowledge.

The 1950s witnessed the development of area checklists, spearheaded by Mary Parke’s 1931 Manx Algae and her 1953 “A preliminary check-list of British Marine Algae.” Lily Newton’s 1931 Handbook provided the first identification key for British Isles algae, but it wasn’t until the 1960s that the development of such keys became standard practice.

With the rise of ecological studies in the 1980s, there was a surge in research into algal communities and their role within larger plant communities. This period provided an additional tool for explaining geographical variation.
