Since then, 58 taxa including 1 new species and 1 new variety from Lake Suwon Seoho have been reported by Skvortzow (1929). He first reported the genus Cenritractus in Lake Suwon Seoho. Studies of freshwater algae in Korea were begun by Kawamura (1918). Thus, they play an important role in the primary and secondary successional processes (John and Tsarenko 2002). From the spring to fall, in particular, their reproduction is extensive such that they impart a green vegetation-like color to the water (Hindak 1977). They occur in the plankton and benthos of mesotrophic or eutrophic waters, and are the most diverse with the highest abundance.

Chlorococcal algae are mostly unicellular or may form colonies of a definite shape (Prescott 1962). The Chlorococcales are a large number of species, which are predominantly aquatic system and have the widest distribution among the Chlorophyceae.

Green algae comprise 7 orders (i.e., Volvocales, Tetrasporales, Chlorococcales, Microsporales, Chaetophorales, Oedogoniales and Zygnematales), but one of the orders, Zygnematales is separated into the Class Zygnematophyceae from Chlorophyceae by some researchers (Round 1971, Kenrick and Crane 1997). They are closely related to the higher plants in phylogenetic, which have similar structures in their chloroplasts, and photosynthetic pigments (chlorophyll-a, b and carotenoids) and store of starch (e.g., pyrenoid). The freshwater green algae have great diversity in their cellular organization, morphological structure, and reproductive processes than that of any other algae (Bold et al. (Come to both performances if you can, the price is the same.Freshwater green algae (Chlorophyta) are characterized as the largest and most varied algal phylum. Reservations: 1,000 baht per person for either one or both of these performances. This is a very testing work and I'm confident that Suvida will give us a compelling performance. Like the great opus 110 of Beethoven, the Wanderer culminates in a fugue, in this case grand and triumphal - no doubt an inspiration to Liszt who transcribed the work for orchestra and whose own Sonata in B minor reaches a similar apotheosis. There are no clear breaks between movements which gives the work a sense of unity. But all four are based on the same theme taken from the composer's song, The Wanderer. It is a titanic work, technically challenging for the performer both in texture and structure. The Fantasy was composed in 1822, a year after Beethoven's Sonata opus 110 (see above). 'The devil may play it,' said Schubert of his most technically demanding keyboard work. It shows the mettle of any serious pianist.įranz Schubert's Wanderer Fantasy. This sonata is one of Beethoven's most sublime works. The slow movement returns for a few plaintive, contemplative breaths before creeping back to the fugue, this time inverted, in emulation of Bach's fugues and culminating in a robust, tumultuous, crescendo. The fugue creeps out from the slow movement and takes the form of a dance, building in a slow, restrained crescendo. The slow movement is in the nature of a recitative - a continuous line of melody. The sonata proceeds in a medley of slow movement and fugue.

The scherzo is playfully centered on two lumbering folk songs, 'Our cat had kittens' and 'I'm a slob and you're a slob', perhaps taking a leaf from the Quodlibet in Bach's Goldberg Variations, which elevated drinking songs to the high art of polyphony. The first movement is gentle and mellifluous. It is written in three or four movements, depending on who is analysing it. It is the penultimate of Beethoven's 32 sonatas, completed in 1821. It is a delightful work and will be a joy to hear.īeethoven's piano sonata opus 110 is the most substantial work on the program.

It is the fourth of a series known as the Munich sonatas, or the 'difficult sonatas' and is the only of Mozart's sonatas to begin with a slow movement. Mozart's Sonata K282 is an early work, written in 1775 when the composer was 19.
