The green tide in the Southern Yellow Sea which has been erupting continuously for 14 years. Dominant species of the free-floating Ulva in the early stage of macroalgae bloom were Ulva compressa, Ulva flexuosa, Ulva prolifera, and Ulva linza along the coast of Jiangsu Province. In the present study, we carried out comparative studies on complete mitochondrion genomes of four kinds of bloom-forming green algae, and provided standard morphological characteristic pictures of these Ulva species. The maximum likelihood phylogenetic analysis showed that U. linza is the closest sister species of U. prolifera. This study will be helpful in studying the genetic diversity and identification of Ulva species. 1 Introduction gradually [19]. Thus, it was meaningful to carry out comparative studies on organelle genomes of these Green tides, which occur widely in many coastal areas, bloom-forming green algae. are caused primarily by flotation, accumulation, and excessive proliferation of green macroalgae, especially the members of the genus Ulva [1-3].

Geographical Variation of Development and Life History of Blidingia Minima(Chlorophyceae)From Japan

This taxon was established by KyLIN in 1947 on the basis of culture experiments by BLIDING (1938) who showed that the following features distinguished it from genus Ehateromof7)ha and proposed to establish a new genus: 1) Quadrifiagellate zoospores lacking eyespots are the only repro- ductive cells produced; 2) During germination, all of the cytop}asm of the settled zoospore migrates into a germination tube and is walled off from the empty spore; 3) The germling produces prostrate branches which form an initially rnonostromatic disc that becomes distromatic in the center and gives rise to an ereet, tubular frond with many initial cells. Nearly a hundred years before that, Blidingia minima had been described under the names Ulva intestinalis var. nana by SOMMERFELT (1826), Ehateromo7Pha minima by KUTZING (1849), E. micrococca by KUTzlNG (1856) and E. nana by SJOsTEDT (1939) on the basis of anatomical features. These species were distinguished from other EhateromoiPha species by their small cell size (}ess than 10"m iR surface view), but the criterion among these species was obscure, so there was a taxonomical confusion.

Ulvales, Ulvophyceae) in Mikawa Bay, Japan, Deduced from ITS2 Rdna Region Sequences
Algae Volume 22(3): 221-228, 2007 Species Diversity and Seasonal Changes of Dominant Ulva Species (Ulvales, Ulvophyceae) in Mikawa Bay, Japan, Deduced from ITS2 rDNA Region Sequences Hiroshi Kawai1*, Satoshi Shimada2, Takeaki Hanyuda1, Teruaki Suzuki3 and Gamagori City Office4 1Kobe University Research Center for Inland Seas, Rokkodai, Nadaku, Kobe 657-8501, Japan 2Creative Research Initiative ‘Sousei’, Hokkaido University, Sapporo, 060-0810 Japan 3Aichi Fisheries Research Institute, Gamagori 443-0021, Japan 4Asahimachi, Gamagori 443-8601, Japan Frequent occurrences of green tides caused by Ulva species (Ulvales, Ulvophyceae) associated with eutrophication along enclosed coasts are currently causing environmental problems in coastal ecosystems. In addition, increasing intercontinental introductions of coastal marine organisms, including Ulva, are also a serious issue. However, due to the considerable morphological plasticity of this genus, the taxonomy of Ulva species based on morphological stud- ies is problematic. Therefore, in order to elucidate the species diversity and seasonal changes of the dominant Ulva species in Mikawa Bay, central Honshu, Japan, we made seasonal collections of Ulva species at seven localities, and identified the dominant species using the ITS2 rDNA region sequences. We identified the following nine taxa as common Ulva species in the area: 1) Ulva pertusa Kjellman; 2) U. ohnoi Hiraoka et Shimada; 3) U. linza L.; 4) U. califor- nica Wille; 5) U. flexuosa Wulfen; 6) U. fasciata Delile; 7) U. compressa L.; 8) U. armoricana Dion et al.; 9) U. scandinavica Bliding. Among the species, U. pertusa was most common and dominant from spring to summer, and U. ohnoi from autumn to winter. Ulva californica and U.
