The samples were collected at lowland swamps, reservoirs, mountainous wetlands, and sphagnum bogs from 2012 to 2014. The followings were newly recorded in Korea: two species, three varieties, and one form, including six taxa of the genus Cosmarium. The newly recorded Korean species were Cosmarium bioculatum var. hians, C. bireme, C. pseudobiremum, C. nitidulum var. pseudorectangulare, C. trilobulatum f. retusum, and C. trilobulatum var. depressum. The flora of the genus Cosmarium contains 303 taxa in total in Korea. The specimens were cultured and deposited on the algal culture collection of Kyonggi University (ACKU) and National Institute of Botanical Resources (NIBR).

This study was carried out on freshwater chlorococcal green algae in ponds, swamps, reservoirs, lakes and rivers (290 sites) from May 2012 to January 2014. The family Radiococaceae was identified and classified into 3 genera, 12 species and 1 variety at 23 sites. These taxa were Eutetramorus. nygaardii, E. tetraporus, E. planctonicus, E. fottii, E. globosus, E. polycoccus, Coenocystis planctonica, C. planctonica var. hercynica, C. micrococca, C. subcylindrica, Gloeocystis baneergattensis, G. papuana, and G. polydermatica. These taxa may or not had remnants of the cell wall in the colonial gelatinous envelope for a short time. Of these, 2 taxa are newly recorded in Korea from this study: 1) C. micrococca and 2) G. polydermatica.

A study on fresh-water green coccoid algae was carried out at ponds, swamps, reservoirs, lakes and rivers (290 sites) from May 2011 to January 2014. In this study, 4 genera and 13 taxa of the family Radiococaceae having the remnants of cell wall existing for a long time in the colonial gelatinous envelope are classified and identified from 24 sites. Many taxa of this family, however, have not been recorded in Korea yet. Of these 13 taxa, 5 taxa are newly recorded in Korea by this study: 1) Schizochlamydella solitaria, 2) Thorakochloris planktonica, 3) Radiococcus bavaricus, 4) R. nimbatus, and 5) R. planktonicus.

Freshwater algae (green algae, blue-green algae and flagellated algae) were collected at 103 freshwater sites (including lakes, ponds, swamps, streams, and rivers) throughout South Korea March 2015-October 2016, and were identified using light microscopy. A total of 345 taxa in 2015 and 329 taxa in 2016 were identified and among them, 6 taxa in 2015 and 8 taxa in 2016 were new recorded species in Korea; The new recorded species were Characiopsis malleolus in Xanthophyceae, Phacus mammillatus in Euglenophyceae, Epipyxis utriculus and Lagynion ampullaceum in Chrysophyceae, Bicosoeca planctonica in Bicosoecophyceae and Salpingoeca frequentissima in Choanoflagellatea in 2015, and were Ankistrodesmus bernardii and Quadrigula korsikovii in Chlorophyceae, Didymocystis planctonica in Treubouxiophyceae, Spirulina nodosa, Raphidiopsis curvata and Geitlerinema claricentrosum in Cyanophyceae and Lagynion macrotrachelum in Chrysophyceae, Bicosoeca oculata in Bicosoecophyceae and Salpingeoca rosetta in Choanoflagellatea in 2016.

A histological study on the retina of Misgurnus anguillicaudatus was carried out by light microscopy and scanning electron microscopy as part of getting information about relation between its habitat and visual cells. The visual cells of the retina in M. anguillicaudatus, a bottom-dwelling freshwater pond loach in stagnant or slow waters such as swamps, reservoirs and paddy fields, consists of double cones and large rods. The cones form a row mosaic pattern in which the partners of double cones are linearly oriented with a large rod. In a double cone, the two members are unequal such that one cone may be longer than the other.

The present study summarizes the occurrence, distribution and autecology of 12 taxa of the class Cyanophyceae collected from several swamps, reservoir and highland wetlands in South Korea from 2009 to 2012. A new species, Anabaena koreana sp. nov. and 11 taxa of blue-green algae newly recorded are described and illustrated. Anabaena koreana is similar to A. oumiana, A. spiroides and A. crassa in that the trichomes form regular coils. However, A. koreana is distinguished from these three species by the morphological characteristics of the vegetative cell, heterocyst, and akinet shape and size. This study considers 12 blue-green algal species, including a new species, Anabaena koreana sp. nov. and 11 species that are recorded for the first time in the Korean freshwater algal flora. Among them, the genus Nostochopsis Wood ex Bornet et Flahault 1886 had not previously been recorded in Korea.

Biodiversity af yeasts in various natural environments including soils, swamps and plants was investigated. By molecular identification methods based on the partial sequences of 265 rDNA, 69 isolates were assigned to 44 taxa including 27 known species. The remaining 17 taxa could potentially form new species. All of them were classified into Ascomycota, Hymenomycetes, Urediniomycetes and Ustilaginomycetes. Ascomycetous and ustilaginomycetous yeasts were generally isolated from flower samples, and hymenomycetous and urediniomycetous yeasts were generally isolated from soil samples. Distribution of yeast groups exhibited geographical variation. Yeast biodiversity of root sail also varied according to the associated plant species.

Flies of the genus Scatella are small and dark-gray, and many species have distinctive whitish spots on their gray wings. Most species are found in damp environment, such as the borders of marshes, seashore areas, swamps, lakes, ponds, streams, and paddy fields. The Korean shore fly genus Scatella Robineau-Desvoidy has been taxonomically noted. A total of five species have been identified: S. calida Matsumura, 1915, S. nipponica Miyagi, 1977, S. obsoleta Loew, 1861, S. paludum (Meigen, 1830), and S. tenuicosta Collin, 1930. This is the first report of S. calida Matsumura, 1915 from Korea. A key to the Korean Scatella species and photographs of the external features have been provided.

The purification of sewage deriving from agricultural and food industries is today a serious problem mainly in areas characterized by intensive production plants. The solution examined in this work, involves a system of natural evaporation which employs special panels with a large evaporating surface constituted by an internal cellular structure in polyethilene. Using renewable energy they allow to speed up the natural evaporating effect thus eliminating some drawbacks such as swamps and obtaining sewage concentration with relatively low costs. The institute of agricultural engineering has carried out tests on the disposal of sewage deriving from two very important production sectors; pig-breeding and olive oil production . at a were gathered in order to verify the operating capacity of plants and their variables . On the remaining concentrated part tests were also carried out in order to know its chemical and chemical-physical features and to study the possibility for its us .

This study summarizes the taxonomic notes and distribution of 13 taxa of the genus Scenedesmus (Chlorophyceae) collected from several swamps, reservoirs, and rivers throughout South Korea from 2012 to 2014. In this study, light microscopy images of all 13 taxa are presented and briefly discussed with regard to their taxonomy, distribution, and ecology and environmental factors of occurrence sites. All 3 subgenera (subgenus Scenedesmus 1 taxon; subgenus Acutodesmus 2 taxa; subgenus Desmodesmus 10 taxa) are newly described in Korean freshwater algal flora: S. linearis, S. acuminatus var. elongatus, S. acuminatus var. tetradesmoides, S. carinatus, S. denticulatus var. disciformis, S. gutwinskii var. heterospina, S. helveticus f. bicaudatus, S. lefevrei, S. oahuensis var. clathratus f. longiclathratus, S. oahuensis var. clathratus, S. pannonicus, S. polydenticulatus, and S. tenuispina.
