    本研究では,動物園等の展示施設において,来園者の印象の変化を視覚化し,その傾向を多角的に分析するための手法の開発を目的としている.横浜市立金沢動物園の協力を得て,動物園の観覧ルートに沿って観察ポイントを設定し,それぞれのポイントで体験した印象をカラーの付箋紙に記入してもらい,マップと対応付けることで主観的な印象をカラー濃度でのマップとして表すことを試みた.また,カラー濃度マップを参照しながらイラストマップを作成し,2つのマップを組み合わせて見ていくことで,展示施設で体験した印象の分析を試みた.実験は2回実施し,それぞれの結果を比較したところ,「動物園を訪れた季節」と「動物園に行った回数」によって違いがあることがわかった.今回の分析方法を用いることで,来園者が体験した印象を多角的に分析することが期待できる.

     国内に150施設以上存在し,6000種以上の多種多様な動物を飼育している動物園水族館には,その多様な動物を活かし,保全するために,広範な分野の研究を進めることが期待されている。動物園水族館は幅広い種の動物を人の管理下に置いているため,様々な研究検体の収集が容易である。検体を計画的,体系的に収集,整理,保存できれば,効率的に利用することができ,より大きな研究成果が得られると考えられるため,そのような取り組みが,世界各地で進められており,国内の動物園水族館でも徐々に広がっている。大阪市の天王寺動物園では150種以上の動物の組織を凍結保存しており,検体バンク化を目指している。公益社団法人日本動物園水族館協会では,生殖細胞の組織的な収集,保存に取り組んでおり,配偶子の共有体制が整いつつある。動物園水族館が博物館と連携することにより,双方の長所を活かした効果的な検体の収集,保存を進めている事例も存在している。今後この取り組みを発展させていくためには,保存されている検体の利用活性化や利用時のルール整備,動物園水族館自身の研究能力の強化などが必要とされる。動物園水族館は様々な動物の研究を進めるにおいて独自の重要な役割を占めているが,検体の収集,保存もその役割の一つとして,今後より重要視されることに間違いはないと思われる。

    In Central Asia, large-scale expansion of agriculture in Aral Sea basin caused by heavy exploitation of irrigation water from international rivers in the early 1960's. This resulted in the rapid shrinking of the natural wetlands and significant change in the ecosystems. The decrease in river water and the resultant shrinking of the water area have led to destruction of the natural environment. To evaluate such landscape changes satellite remote sensing is most useful. Thus, we started monitoring the ecosystem through investigation and using satellite remote sensing. The study site is the lower Syr-Darya region where is considered as the most unstable in the catchment environment. Ground-truth data of land surface was collected through expeditions from 1999 to 2003. Based on floristic composition and soil investigation, vegetation was classified by using multivariate and cluster analyses. Based on the classification, spectral reflectance, biomass, LAI and plant coverage were measured on each type of vegetation in summer, 2002 and 2003. We found that LAI is a good estimate of biomass, and LAI can be estimated from either NDVI or TSAVI depending on vegetation type in this region. Using these data and methods, we analyzed succession of vegetation on the dried bottom of Aral Sea and relationship between wetland and river flow changes, relationships between the occurrence of Pelican's colony and environmental factors of each lake. From the results, we found that artificial water control of upper irrigational canal is most important to rehabilitate declined ecosystem in this region. It is concluded that maintenance of water consumption will affect wetlands maintenance and preservation of water fowl.

    18目42科105属147種(亜種を含む)353個体の日本産および外国産の成鳥と推定した鳥類の晒骨標本を作成し,胸椎について胸椎数とnotariumの形成様式を検索した.
    (1)胸椎は6-12個と変異に富んでいた.椎骨数は同一科内,同一種内でも変異が大きかった.
    (2)Notariumは9目12科42種103個体の鳥類に存在した.
    (3)Notarium の存否,それを形成する胸椎の数や位置,胸椎の synsacrum への参加数は胸椎数と同様に同一科内,同一種内においても変異が大きかった.
    (4)Notarium は飛翔力の弱いキジ目の全種に存在する一方ゴハト科,ハヤブサ科,ツル科そしてフラミンゴ科などにも存在するので notarium の存否を飛翔と短絡的に関係づけることはできないと推察された.

    Although white and grey forms had long been known in Japanese Crested Ibis Nipponia nippon, its scarcity prevented detailed research. Contrary to a former opinion that these were color phases, Mr. H. Sato (1957) considered them as seasonal forms and later suggested (1968) that the grey form is caused by cosmetic coloration toward breeding season.
    This paper presents a detailed analysis on the mechanism of this type of color change based on numerous feather samples offered to Yamashina Institute by Mr. Y. Muramoto who collected them in its natural habitat in Ishikawa for many years. Supplemental observations were made with live birds in Sado I. with valuable assistance of Messrs. K. Chikatsuji and T. Takano of Ibis protection Center. Histological studies were made by the author at Department of Zoology, Tokyo University.
    Some important points clarified in this paper are as follows:
    1. The feather samples suggested neither of the known types of color change: 1) molting, 2) abrasion, 3) cosmetic staining with color substance in preen oil, 4) photo chemical change of biochrome in the feather, and 5) external staining (e. g. iron in water birds).
    2. Under the feathers surrounding the naked face of Japanese Crested Ibis, a particular area of the skin was found producing 'black substance.' (Fig. 12).
    3. A few tiny samples of this black substance fell on the snow when a captive ibis scratched that region of the head (Fig. 13, 14). These could be collected and used for chemical analysis (to be published elsewhere).
    4. Prior to the breeding season, in late January through February, a characteristic behavior of rubbing the side of its head to the shoulder region was observed after bathing. This was named 'daubing behavior' (Fig. 16) and it lasted 20-30 minutes followed by normal preening.
    5. The grey, or rather blackish, tint of the neck to shoulder region got deeper as the 'daubing behavior' was repeated.
    6. Histologically, it was proved that the grey tint was caused by external adherance of 'black substance' to the proximal (not distal) barbules of the normal white feathers (Fig. 4-10).
    7. The black substance on the feathers and those picked up after head scsatching were identical microscopically and chemically. These are supposed to come out along feather pores of the skin, since the feathers of the black substance producing area had black ring near the root of the rachis (Fig. 2, 9, 10).
    8. The change from grey to white form occurred by normal post-nuptial molting (Fig. 17) and neither 'daubing behavior' nor dropping of black substance was observed after bathing in this period.
    9. The 'daubing behavior' was so important in this new type of plumage color change that even during the critical period of change from white to grey form, the white plumage remained untinted unless this behavior was performed, which always occurred after bathing. Five to six bathing-'daubing behavior' sequences completed a typical grey form. The first bathing of the season was observed on a fine day in late January.
    10. Physio-ethological mechanisms and the hormonal control involved were analysed (Fig. 20) and significance of the grey form was discussed eco-evolutionarily.

    We collected data to see which bird taxa possess unique feather structures, namely the after-shaft and tegmen, as a basis for bird feather identification. Using the collection of the Yamashina Institute for Ornithology, we examined 19 orders, 75 families and 529 species for tegmen feathers, and 18 orders, 44 families and 334 species of non-passerines and six families of passerines for after-shaft feathers. We also examined the authors' personal collection of passerines feathers for after-shaft feathers. After-shafts were present in 15 orders, 35 families and 246 species of non-passerines and 29 families of passerines, and tegmen was present in six orders, nine families and 86 species.

    Anthropogenic dynamics of vegetation caused by large scale of irrigation project have been illustratedon the examples of Middle Asia, with special reference to Kazakhstan.
    (1) The Aral Sea was regarded worthless as compared to the irrigation agriculture by the authorities 20years ago.
    (2) Possible plant productivity with irrigation is very high in such dry area, however extensive andcareless irrigated agriculture has caused severe salinization.
    (3) There are not only the ecosystems adopted to dry condition supported by little precipitation but alsowetland ecosystems supported by rivers from mountains with glaciers.
    (4) Traditional land use of nomadism and the Silk-road have close relationship to the natural environmentwhich is the suitable area for agriculture.
    (5) On the other hand, large scale of irrigation agriculture seems to be planned from the view point ofeffective construction and has less consideration to the sustainability.
    (6) Active invasion by plants can be seen in the dried up region of Aral Sea, however saksawool, whichis the most important tree species of this region could not be found.
    (7) Rice production is an ecological land use, however it is in a trade off relation with the naturalwetland.
    (8) Land use with ecological consideration, control of water use to preserve natural wetland of the Ili andrevegetation of saksawool and wetland forest are the main subjects to be carried out from the viewpoint of landscape ecology.
