  5. Bats from Kunashir and Iturup Island

    Kawai, Kuniko; Mikhail P, Tiunov; Kondo, Norihisa; Maksim A, Antipin; Victor N, Boiko; Ohtanishi, Noriyuki; Dewa, Hiroshi
    Recent extensive bat surveys between 2010 and 2013 in Kunashir Island and the middle part of Iturup Island have brought about new important contributions on the bat fauna in islands. In Kunashir Island, we found 7 of the 8 species (Barbastella leucomelas, Plecotus sacrimontis. Myotis gracilis, My.ikonnikovi, My macrodactylus , My.petax and Murina ussuriensis), which were previously reported, and 2 additional species ( Eptesicus nilssonii and Myotis nattereri),which has been reported, In the middle part of Iturup Island, we found all of the 4 species( Eptesicus nilssonii,Plecotus sacrimontis, Myotis gracilis and My. petax ),which were previously reported. Our surbeys show...

  6. Marine Benthic Macroalgae Survey 2010–2012 around Shikotan, Iturup and Kunashir Islands

    Abe, Tsuyoshi
    In a field survey of marine benthic macroalgal species around Iturup, Kunashir (conducted in 2012) and Shikotan (conducted in 2010) islands, 77 species were identified. Although this number is the half of number found 70 years earlier by Nagai (1940, 1941), biodiversity loss is not suggested. Rather, the survey methods may have resulted in the underrepresentation of previously identified species. Several species described in Nagai's studies were found in this survey. Using the collected material, the taxonomic classification of Cymathaere fibrosa and Laminaria sikotanensis may be reexamined with molecular methods. The dominant species in the kelp forests differed between the...

  7. Inocybe (Agaricales, Inocybaceae) Collected in the Islands of Iturup and Kunashir

    Kobayashi, Takahito; Terashima, Yoshie
    This paper considers four species of Inocybe occurring in Iturup or Kunashir as new records: (1) Inocybe maculipes (Section Tardae) has smooth basidiospores and caulocystidia at stipe apex; (2) Inocybe splendens var. splendens (Section Splendentes) has smooth spores and caulocystidia throughout; (3) Inocybe taxocystis (Section Inocybe) has nodulose spores and caulocystidia at stipe apex; and (4) Inocybe intricata var. pallidistipata (Section Marginatae) has nodulose spores and caulocystidia throughout.

  8. Vascular Plants Collected at Tornaya Bay, Iturup Island in 2012

    Takahashi, Hideki; Fukuda, Tomoko
    A list of 109 species in 40 families of vascular plants around Tornaya Bay, Iturup Islands was prepared based on a field survey in 2012. The biased composition of the ten dominant families at Tornaya Bay may be influenced by the local coastal meadow vegetation of the region. Forest vegetation is poor around Tornaya Bay. Among the noteworthy discoveries was Agrimonia pilosa Ledeb. var. succapitata Naruhashi.

  9. Vascular Plants Collected on the Veslovskiy Peninsula, Kunashir Island in 2012

    Takahashi, Hideki; Sato, Hiroyuki; Kato, Yukie; Fukuda, Tomoko
    During a field trip in 2012 to the Veslovskiy peninsula of Kunashir Island in the southern Kurils, 72 species in 24 families of vascular plants were collected. The floristic composition of Veslovskiy was compared with Notsuke of eastern Hokkaido. The general flora is similar between the two regions, except that forest vegetation is lacking in Velslovkiy. The relative dominance of the families; Rosaceae, Ranunculaceae, Ericaceae, and Violaceae in Notsuke can be explained by the presence of the forest vegetation. We could not confirm the forest vegetation in Veslovskiy. Rhinanthus minor and Leontodon autumnalis, which occur on Kunashir, are naturalized plants...

  10. Vascular Plants Collected in Peschanoye Mire (Tōfutsu-sitsugen), Kunashir Island in 2012

    Takahashi, Hideki; Sato, Hiroyuki; Kato, Yukie; Fukuda, Tomoko
    During a field trip in 2012 to Peschanoye Mire, situated on the SE side of Lake Peschanoye, Kunashir Island, in the southern Kurils, 105 species in 42 families of vascular plants were collected. Among them, Carex cespitosa is reported for the first time from Kunashir Island. The ratio of naturalized to native plants on Peschanoye (4 spp., ca. 4%) is much lower than that inKushiro Mire (85 spp., ca. 11%). The Pinus pumila scrub in the mire of Peschanoye is noteworthy.The rare occurrence of Alnus japonica is another characteristic of Peschanoye Mire.

  11. Aquatic Plants Collected in Kunashir and Iturup Islands, in 2012

    Yamazaki, Mami; Sato, Hiroyuki; Kato, Yukie; Fukuda, Tomoko; Takahashi, Hideki
    A list of 37 species in 16 families of aquatic plants was prepared based on a field trip to Kunashir and Iturup Islands in 2012. Common aquatic plants in the islands of Kunashir and Iturup are Potamogeton perfoliatus, P. praelongus, Persicaria amphibia and Hippuris vulgaris.We recorded eight species of Potamogeton. The temperate family Hydrocharitaceae and the genus Trapa were not found.

  12. Plant List of Poaceae Collected on Kunashir and Iturup Islands on a Botanical Expedition in 2012

    Sato, Hiroyuki; Kato, Yukie; Fukuda, Tomoko; Takahashi, Hideki
    A total of fifty species in the family Poaceae were collected on a botanical expedition to the islands of Kunashir and Iturup in the southern Kurils in 2012. The collected Poaceae specimens were confirmed using Flora of the Kuril Islands (Barkalov 2009) for comparison. As a result, Sasa nipponica is considered to be a new record for the Kurils. Two infraspecific taxa, Anthoxanthum odoratum var. alpinum and Elytrigia repens var. aristata, are also considered tobe new records for the Kurils, and Lolium perenne, a naturalized plant, is also new record for the southern Kurils.o the islands of Kunashir and Iturup...

  13. Colonization of Sandy Environment by Calamagrostis neglecta(Poaceae) in Serebryanoye Mire, Kunashir Island

    Sato, Hiroyuki
    Calamagrostis neglecta (Ehrh.) P. Gaertn., B. Mey. & Schreb. was observed growing on exposed sandy ground in Serebryanoye Mire on Kunashir Island in the southern Kuril Islands in 2012. The observation is noteworthy because C. neglecta typically grows in bogs and not in sandy environments. However, the high frequency of fog in the Yuzhno-Kuril’sk area is considered to supply the plant with sufficient water to support growth in sandy environments.

  14. Recent Condition of the Conservation Status of the Furukamappu Mire (Lake Serebryanoye), Kunashir Island

    Kato, Yukie; Sato, Hiroyuki
    There are several sand dunes in southern part of the Furukamappu Mire (lake Serebryanoye)and the rare community Picea glehnii forests on sand dunes were observed. The plants growing this area were recorded by observation and specimen collection, and we discussed the conservation status of this mire. Construction of an electric pylon caused some damages to the sand dunes, but few exotic species were observed in the area. However, numerous exotic plant species typically associated with urban areas were observed along the rode around Furukamappus Pond.

  15. Flora List of Stolbovskyy (Shimanobori) Nature Observation Road,Kunashir Island

    Kato, Yukie; Fukuda, Tomoko
    The change of landscapes from evergreen coniferous forest, through mixed forest, to deciduous broadleaf forest was observed along the Stolbovskyy nature observation road on Kunashir Island. The plants growing adjacent to this road were recorded by eye, specimen collection, and taking photographs

  20. Study on the production region of iron goods and the roots of forging technology of the Okhotsk Culture

    Amano, Tetsuya; Akanuma, Hideo; Kharinskiy, Artur V.
    The forging technology of the Okhotsk culture, using pottery shards in substitution for tuyere and for furnace walls, was quite unique. The author had an assumption that based on this technology there were two kinds of metallurgical processes of techniques, facilities, raw materials, and products in the Okhotsk culture. One is the relatively popular forging, operating by twin blowing through two shards constructing the furnace. The raw material used is steel. The other is the refining of high carbon material or cast iron into steel using single blowing associated with heavy slag as a byproduct. While for a long time...
