。在红树林下可找到丰富的底栖无脊椎动物，夏天更有多种雀鸟在红树林筑巢栖息。 - 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
隐种广泛存在于各类海洋生物中,尤其是底栖无脊椎动物.然而,海洋终生浮游生物由于具有较强的扩散能力,往往被视为生物多样性低、物种形成慢.本文就海洋终生浮游生物隐种与物种形成的研究作一综述.基于研究的38个种类,结果表明: 1 )海洋终生浮游生物普遍存在隐种,其物种形成要比想象得快; 2 )由于引种的广泛存在,形态种生物多样性无法反映海洋终生浮游生物真正的物种多样性; 3 )地理隔离有助于海洋终生浮游生物隐种的形成,但异域物种形成的作用仍值得商榷; 4 )生态物种形成很可能是海洋终生浮游生物物种形成的主流模式.海洋终生浮游生物强基因流下快速的物种形成有悖于生物进化常理,解决该悖论将有助于我们对海洋物种形成和生物多样性的理解
