中文摘要 | 以同功 的資料分析採自台灣六條河川中的 屬與馬口魚屬魚類。在13個酵素系 統中共得到26個基因座,78個對偶基因。 屬的二個種間(粗首 與平 )的Nel's遺 傳距離為0.285,相當於屬內的分化程度。粗首 具有較大的首裂,較多的側線鱗片數,以 及在mMDH*100, ME-1*100, PGI-B*100, PGM-1*100, 與PGM-2*100 in Zacco等對偶機因上 與平 有所區別。在屬間方面,若與菊池式細 比較,馬口魚顯然與 屬的二種魚類關係 較遠,因此它們應為不同屬。馬口魚的嘴角有口鬚,並且在sAAT-1*120, CK-A*93, FH-1*80, FH-2*82, G PDH-1*80, IDHP-1*113, IDHP-3*120, ME-1*103, ME-2*50, PGM-1*120,與 PGM-2*120等對偶基因上可明顯與 屬魚類有別。文中並討論 屬在臺灣的起源以及可能 的種化時間。 |
英文摘要 | Hurng-Yi Wang, Sin-Che Lee and Ming Jenn Yu (1997) Genetic evidence to clarify the systematic status of the genera Zacoo and Candidia (Cypriniformes: Cyprinidae). Zoological Studies 36(3): 170-177. Genetic relationships among species of the genera Zacco and Candidia were analyzed using allozyme data from sampled specimens collected from 6 rivers in Taiwan. A total of 78 alleles were resolved for 26 loci from 13 enzyme systems. Nei's genetic distance between 2 congeneric species (Zacoo pachycephalus and Z. platypus) was 0.285, which is within the range for the same genus. A slightly larger mouth cleft, smaller lateral line scales, and fixed alleles at mMDH*100, ME-1*100, PGI-B*100, PGM-1*100, and PGM-2*100 in Zacco pachycephalus can be used to distinguish it from Z. platypus. Comparison with Aphyocypris kikuchii,Candidia barbatus showed more distant replationship with these 2 Zacoo species, suggesting that Zacoo and Candidia are 2 distinct genera. In addition, a barbell at mouth corner, and fixed alleles at sAAT-1*120, CK- A*93, FH-1*80, FH-2*82, G PDH-1*80, IDHP-1*113, IDHP-3*120, ME-1*103, ME-2*50, PGM-1*120, and PGM-2*120 in Candidia can also be used to distinguish it from the genus Zacco. The colonization and speciation event of the genus Zacco in Taiwan was discussed in detail. |
