  • 自1992年10月至1994年3月,在翡翠水庫附近大桶山區的一個靜止水域
    進行共棲蛙類的資源分配利用之研究.目的在於暸解台灣的共棲蛙種如何分
    隔彼此的生態棲位?
    研究期間一共記錄到5科12種蛙類,其中斯文豪氏蛙(Rana narina sw-
    inhoana)及澤蛙( Rana limnocharis limnocharis)出現次數很少所以不列
    入資源利用的探討。其餘10種依其利用微棲地的比例,利用群集分析法分析
    ,結果可以看出此群聚共有三群;翡翠樹蛙(Rhacophorus smaragdinus)、
    白頷樹蛙(Polypedates megacephalus)﹑面天樹蛙(Chirixalus idiooto-
    cus)﹑中國樹蟾(Hyla chinensis)及臺北樹蛙 (Rhacophorus taipeianus)
    為樹棲性蛙類群;拉都希氏蛙(Rana latouchii)﹑腹斑蛙(Rana adenopleu-
    ra)﹑長腳赤蛙(Rana longicrus)及盤古蟾蜍 (Bufo bufo gargarizans)為
    地棲性蛙類群; 小雨蛙(Microhyla ornata)則自成一群,主要微棲地選擇是
    草地.以主成份分析(PCA)來看,樹棲性蛙類較依賴植物,而地棲性蛙類較依
    賴水池,小雨蛙的活動範圍較遠離水池.
    樹棲性蛙類群中中國樹蟾及翡翠樹蛙在植物上停棲高度和其他種類彼
    此間皆有差異,而其餘三種則停棲高度重疊。活動的時間翡翠樹蛙全年皆
    可活動,高峰在3至4月及9至10月;台北樹蛙則利用冬天活動;其餘3種則
    皆利用3至8月活動,活動高峰與翡翠樹蛙隔開。生殖場所的選擇,翡翠樹
    蛙及白頷樹蛙在樹上,臺北樹蛙則把卵泡產在地面的洞穴中.
    地棲性蛙類群中拉都希氏蛙、長腳赤蛙及盤古蟾蜍主要是利用冬天活
    動,腹斑蛙以夏天為主要活動期。拉都希氏蛙把卵黏附在水中落葉上,和
    其他種類不同。小雨蛙活動期是3至8月。
    食性的記錄,發現樹棲性蛙類空胃的情形很多,對食物的選擇沒有發
    現純地棲性的種類。地棲性蛙類中食性以盤古蟾蜍最複雜;小雨蛙偏好食
    用螞蟻。
    生態棲位寬度在微棲地、時間及食性三象限平均值,樹棲性蛙類以翡
    翠樹蛙最高(3.27),地棲性蛙類以拉都希氏蛙最高(5.56),小雨蛙介於中
    間(4.56)。生態棲位重疊度,在群內重疊度較高,群間則重疊度不高。

    The resource partitioning of frog community in a small still
    water pond werestudied from October,1992 to March ,1994 at Tatung
    Shan Area near Feitsui Dam in northern of Taiwan .
    There were 12 species in 5 families of frogs were recorded
    during the research period. Because very few of the datas, Rana
    narian swinhoana and Rana limnocharis limnocharis were excluded
    form this study. The other 10 species were clustered by cluster
    analysis, base on the microhabitat they used. There were 3 groups
    in this community.Rhacophorus smaragdinus,Polypedates
    megacephalus , Chirixxalus idiootocus, Hyla chinensis and
    Rhacophorus taipeianus in one group, I called them tree dwelling
    group. Rana latouchii, Rana adenopleura, Rana longicrus, Bufo
    bufo gargarizans in one group, I called them Land dwelling
    group. The special one is Microhyla ornata, it in one group by
    itself. The majority microhabitat Microhyla ornata chose was
    grass land. The result of Principle omponent Analysis(PCA) showed
    that the tree dwelling group relyed on tree, the water attaracted
    the land dwelling group. The activity area of MIcrohyla ornata
    was most far away from pond.
    In tree dwelling group, the perched height of Hyla chinensis
    and Rhacophorus smaragdinus were different with the other 3
    species. Rhacophorus smaragdinus appeared all over the year,
    the peak of activity falled on March to April and September to
    October. Rhacophorus taipeianus appeared in winter. Hyla
    chinensis, Polypedates megacephalus and Chirixalus idiootocus
    appeared from March to August, the peak was seperated with
    Rhacophorus smaragdinus. Rhacophorus smaragdinus and Polypedates
    megacephalus laied their egg mass on the tree, the Rhacophorus
    taipeianus laied its egg mass on the hole of ground.
    In land dwelling species, Rana latouchii , Rana longicrus
    and Bufo bufo gargarizans activity in winter, Rana adenopleura
    appeared in summer. Different with the other, Rana latouchii make
    its egg attached on the fallen leaves in the water. Mycohyla
    ornata also appeared from March to August.
    There were no obviously difference in food habit of these
    frogs. The empty stomach easly found on tree dwelling species and
    they didn't choose the food only living on the ground. Bufo bufo
    gargarizans was most complicated in choosing food . Micohyla
    ornata prefered ants.
    The average breadth of Niche on microhabitate , time and
    food dimensions , Rhacophorus smaragdinus was heighest in tree
    dwelling group(3.27), Rana latouchii was heighest in land
    dwelling group(5.56), Microhyla ornata located in the middle
    (4.56). The degree of intragroup Nich overlap was heigher than
    itergroup.
