例句与用法

1. 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

百科释义

Allopatric speciation (from the ancient Greek allos, "other" + Greek patra, "fatherland") or geographic speciation is speciation that occurs when biological populations of the same species become vicariant ? isolated from each other to an extent that prevents or interferes with genetic interchange. This can be the result of population dispersal leading to emigration, or by geographical changes such as mountain formation, island formation, or large scale human activities (for example agricultural and civil engineering developments).
