Cryptic species have been found in a wide range of marine organisms ; with majority of them are benthic invertebrates. in contrast, marine holoplanktons are thought to have lower diversity and slow speciation due to their strong dispersal potential. this paper reviewed studies on cryptic species and speciation in marine holoplankton. based on findings in 38 studied taxa, it was concluded that : 1 ) cryptic species are pervasive in marine holoplankton, suggesting holoplankton speciation was more active than previously thought ; 2 ) current morphospecies diversity is untenable to reflect true species diversity in marine holoplankton ; 3 ) geographic isolation may facilitate cryptic speciation of marine holoplankton. however, contribution of allopatric speciation is still questionable ; 4 ) ecological speciation may be the prevailing speciation mode in marine holoplankton. cryptic speciation in marine holoplankton is paradoxical, because rapid speciation under strong gene flow is countertuitive. solution of this paradox will help us gain deep insights of marine speciation and biodivesity
隱種廣泛存在於各類海洋生物中,尤其是底棲無脊椎動物.然而,海洋終生浮游生物由於具有較強的擴散能力,往往被視為生物多樣性低、物種形成慢.本文就海洋終生浮游生物隱種與物種形成的研究作一綜述.基於研究的38個種類,結果表明: 1 )海洋終生浮游生物普遍存在隱種,其物種形成要比想象得快; 2 )由於引種的廣泛存在,形態種生物多樣性無法反映海洋終生浮游生物真正的物種多樣性; 3 )地理隔離有助於海洋終生浮游生物隱種的形成,但異域物種形成的作用仍值得商榷; 4 )生態物種形成很可能是海洋終生浮游生物物種形成的主流模式.海洋終生浮游生物強基因流下快速的物種形成有悖于生物
進化常理,解決該悖論將有助於我們對海洋物種形成和生物多樣性的理解
