中文摘要 | 自2009年4月9日起至2011年4月8日止,針對台灣的12條主要河川、小溪及池塘濕地設置113個樣區進行採集,共獲得貝類標本2,150個,分屬18科26屬38種;種類最多的科為錐蜷科及蜑螺科,兩者都有7種;數量較多的前5種依序為台灣粟螺(11.1%)、囊螺(9.6%)、台灣椎實螺(9.6%)、瘤蜷(9.5%)及臺灣蜆(8.2%)等;外來種有囊螺、福壽螺、梯形福壽螺及印度扁蜷等。各河川、小溪與濕地之間的軟體動物組成差異很大,相對數量之相似度介於8.7至77.2%之間;物種組成之地理分佈(北、中、南及東部)沒有顯著差異。就這兩年整體調查的河流、小溪及池塘濕地而言,種的豐度為4.82、均勻度為0.79、歧異度為2.87。部份種類的棲息地快速消失,如截尾螺科台灣釘螺的棲息地僅剩下屏東縣五溝水及宜蘭縣小埤,沼螺科也有類似的棲地環境變化,亟需大家關心。此外,高雄洲仔濕地產的東京扁蜷為台灣的新紀錄種。 |
英文摘要 | All freshwater mollusk samples were collected from April, 2009 to April, 2011, by a stainless steel mesh method. The samples were collected from 113 sampling sites which comprehended the twelve main rivers and several wetlands in Taiwan. There were 2,150 individuals been collected, and they were recognized to belong to 18 families and 38 species. The most distinguished families of the above were Thiaridae and Neritidae, both had seven species. In terms of the relative abundances, the main species of freshwater mollusks in Taiwan were Stenothyra formosana (11.1%), Physa acuta (9.6%), Auricularia swinhoei (9.6%), Tarebia granifera (9.5%), and Corbicula fluminea (8.2%), respectively. The Shannon-Wiener diversity index of Taiwan freshwater mollusks was 2.87. The rare and endemic species, Oncomelania formosana (Truncarellidae) could only find in Ping-Tung and Yi-Lang counties. The Gyraulus tokyoensis (Planorbioidae), collected from Jhouzai Wetland of Kaohsiung, was a new record in Taiwan. |
