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.
Hidden species are widely found in all kinds of marine life, especially in benthic invertebrates.However, marine life-long plankton are often regarded as having low biodiversity and slow species formation due to their strong ability to disperse.In this paper, Based on the 38 species studied, the results show that: 1) marine life-long plankton commonly exist hidden species and their species formation is faster than imagined; 2) due to the widespread introduction , Morphological biodiversity can not reflect the true species diversity of marine life-long plankton; 3) geographical isolation contributes to the formation of marine life-long plankton hidden species, but the formation of exotic species is still debatable; 4) the formation of ecological species is very May be the mainstream model of marine life-long plankton species.Large life-long plankton Strong gene flow of rapid species formation is contrary to the biological evolution of common sense, to solve the paradox will help our understanding of marine species formation and biodiversity.
