Biogeography and Evolution of the Carassius Auratus-Complex in East
Takada et al. BMC Evolutionary Biology 2010, 10:7 http://www.biomedcentral.com/1471-2148/10/7 RESEARCH ARTICLE Open Access Biogeography and evolution of the Carassius auratus-complex in East Asia Mikumi Takada1,2*, Katsunori Tachihara1, Takeshi Kon2, Gunji Yamamoto2, Kei’ichiro Iguchi3, Masaki Miya4, Mutsumi Nishida2 Abstract Background: Carassius auratus is a primary freshwater fish with bisexual diploid and unisexual gynogenetic triploid lineages. It is distributed widely in Eurasia and is especially common in East Asia. Although several genetic studies have been conducted on C. auratus, they have not provided clear phylogenetic and evolutionary descriptions of this fish, probably due to selection bias in sampling sites and the DNA regions analysed. As the first step in clarifying the evolutionary entity of the world’s Carassius fishes, we attempted to clarify the phylogeny of C. auratus populations distributed in East Asia. Results: We conducted a detailed analysis of a large dataset of mitochondrial gene sequences [CR, 323 bp, 672 sequences (528 sequenced + 144 downloaded); CR + ND4 + ND5 + cyt b, 4669 bp in total, 53 sequences] obtained from C. auratus in East Asia. Our phylogeographic analysis revealed two superlineages, one distributed mainly among the Japanese main islands and the other in various regions in and around the Eurasian continent, including the Ryukyus and Taiwan. The two superlineages include seven lineages with high regional specificity that are composed of endemic populations indigenous to each region. The divergence time of the seven lineages was estimated to be 0.2 million years ago (Mya) by a fossil-based method and 1.0-1.9 Mya by the molecular clock method. -
Relationship Between Estuarine Shellfish Fauna and Physical Environmental Characteristics for Estuary Conservation in Kyushu, Japan
Current World Environment Vol. 10(3), 715-728 (2015) Relationship Between Estuarine Shellfish Fauna and Physical Environmental Characteristics for Estuary Conservation in Kyushu, Japan REI ITSUKUSHIMA1* and YUKIHIRO SHIMATANI2 1Department of Decision Science for Sustainable Society, Kyushu University, 744, Motooka, Nishi-ku, Fukuoka 819-0395, Japan. 2Department of Urban and Environmental Engineering, Kyushu University, 744, Motooka, Nishi-ku, Fukuoka 819-0395, Japan. http://dx.doi.org/10.12944/CWE.10.3.01 (Received: November 29, 2015; Accepted: December 13, 2015) ABSTRACT The establishment of a conservation strategy or restoration goal for river estuaries requires knowledge of potential biota or possible habitat characteristics. In this study, we investigated the relationship between estuarine fauna and macro scale physical indicators on Kyushu Island, Japan to provide basic information for estuarine conservation. As a result of the classification of shellfish fauna by similarity, the Kyushu region was divided into three groups, namely, 1) southern Kyushu with high wave exposure, long fetch, and low tidal variation; 2) the Ariake and Yatsushiro seas with low wave exposure, short fetch, and high tidal variation; and 3) northern Kyushu with an intermediate fetch and tidal variation. In addition, a number of sites, such as Nakatsu Port, Sone tideland, and the Honmyou River, were classified into geographically different groups. This is because the physical characteristics of these sites were similar to classified groups or shellfish fauna were significantly altered by artificial impacts. As a result of discriminant analysis, the discrimination hit rate of species inhabiting the inner bay or tidal flat was high, whereas that for species using a wide variety of bottom sediment environment was low. -

Mapping of Micro Topography on Hill Slopes Using Airborne Laser Scanning 47 Mapping of Micro Topography on Hill Slopes Using Airborne Laser Scanning
Mapping of Micro Topography on Hill Slopes Using Airborne Laser Scanning 47 Mapping of Micro Topography on Hill Slopes Using Airborne Laser Scanning Tatsuo SEKIGUCHI,1) Hiroshi P. SATO,2) Seiji ICHIKAWA,1) Ryoichi KOJIROI 2) Abstract Rain-induced landslides may result in disaster by destroying homes and buildings. Fluid landslides are characterized by rapid movement and long run-out distance. Aerial photos have been used to observe and measure the slopes. In addition, a new technology called airborne laser scanning, is a promising tool for observing and measuring slopes. In this study, hilly terrain where landslides have occurred was measured by airborne laser scanning. Furthermore micro landslide characteristics such as scars were identified in detail, by combining contour maps based on airborne laser scanning data and remote sensing such as aerial photos interpretation. 1. Introduction laser scanning data measured in Tama Hills near Tokyo. Japan has many hills and mountains, and it is located in humid climate influenced by the wet monsoon. 2. Study area Rain-induced landslides may cause disasters by destroying The Tama Hills are located near the boundary homes and buildings in urban and urbanizing areas. Fluid between the western Kanto Mountains and the Kanto Plain landslides, which are most dangerous and damaging, are (Fig. 1). The Tama Hills lie on the southwest side of the characterized by rapid movement and long run-out distance Tama River, and elevation gradually increases from the (Wang and Sassa, 2002). To elucidate the mechanism of southeast to northwest. Namely, the elevation increases this phenomenon, it is important to measure slopes which from 80 m in the eastern part of Kawasaki and Yokohama have already caused landslides in detail. -

Twenty-four previously known, 2 new, and 4 unidentified species in 17 gen- era and 12 families are recorded. Three dubious literature records are also mentioned. All 30 con- firmed species, except Sanguinicolidae gen. sp. (Aporocotylidae), are described and figured. Life cy- cles are discussed where known. Philopinna kawamutsu sp. nov. (Didymozoidae) was found in the connective tissue between the vertebrae and the air bladder near the esophagus of Nipponocypris tem- minckii (Temminck and Schlegel) (Cyprinidae). Genarchopsis yaritanago sp. nov. (Derogenidae) was found in the intestine of Tanakia lanceolata (Temminck and Schlegel) (Cyprinidae). Asymphylodora innominata (Faust, 1924) comb. nov. is proposed for A. macrostoma Ozaki, 1925 (Lissorchiidae). A key to the families, genera, and species of these digeneans is provided. Host-parasite and parasite- host lists are given. Key words: adult digeneans, Trematoda, parasites, morphology, life cycle, Philopinna kawamutsu sp. -

Juveniles were distributed not only in 18 the surf zone, but also in the freshwater zone and they were particularly abundant 19 associated with aquatic vegetations in the freshwater zone, throughout the sampling period. 20 This distribution pattern suggests that the early life history of the temperate seabass 21 depends more intensively on the river than previously considered.
