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

Based on the analysis of thermal contact metamorphic aureoles, granitoid interior structure, quartz axis fabric and strain characters in the different rock unites of yuanshishan granitoid and its wall rocks, the emplacement mechanism of yanshishan granitoid was studied. the magmatic explictite dynamic was advanced in light of regional stress and magma dynamic research. those conclusion was synthesized to ascertain the emplacement mechanism - granitic magma ascended in dikes with the minimum critical width of the magma ascending channels about 2. 213. 88m and located in the core of yindianshan dome with the passive style of dyke explictite ; the later unite is a kind of multiple emplacement mechanism with the character of active emplacement of ballooning

In contrast, n - acetyl - d - galactosamine, sucrose, d - glucose, glycogen, d - mannose, l - fucose and fetuin had no inhibitory effects on hemagglutination. so the lectin activity in the humoral fluids of amphioxus is sh group - dependent and is specifically inhibited by various d - galactosides. also, the humoral fluids obtained from e. coli - injected amphioxus showed increased agglutinating activity against human b and o, rabbit, grass carp and toad erythrocytes, but not against human a and chick erythrocytes, hinting that there might be two types of lectins in amphioxus humoral fluids

After molting three times, the zoea enter the mysis stage during which they begin to look more like adult shrimp and swim in a characteristic fashion with head and tail pointed downwards at right angles and occasionally performing a sudden retrograde jumping action. this is known as the inversion state, the fry being suspended upside - down in the upper middle region of the pond water. this is, therefore, also called the " inverted suspension phase "
