allopatric speciation
异斑点物种形成
sympatric speciation
同斑点物种形成
3) Geographic isolation may facilitate cryptic speciation of marine holoplankton.However,contribution of allopatric speciation is still questionable;
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;
Polyploidy is a mechanism often attributed to causing some speciation events in sympatry.
多倍性常被当作引起在同一地区并存的物种发生物种形成事件的一种机制。
This conclusion agress with the viewpoint that this species is on the speciation stage of migration towards north.
这一结论支持该种目前正处于向北迁移的分化阶段的观点。
First, there is speciation (species-splitting or cladogenesis), caused by geographical isolation or some other mechanism.
首先，因地理隔离或其它一些机制导致物种形成（物种分裂或系枝进化）。
Cook seems to have been the first to coin the term \'speciation\' for the splitting of lineages or \'cladogenesis,\' as opposed to \'anagenesis\' or \'phyletic evolution\' occurring within lineages.
这一术语与发生在世系内的“前进演化”或“种族的进化”这些提法相抵触。
Jolley(1993)is a study of dissolved phosphorus speciation in the lower molongolo sewage treatment plant(Canberra, Australia)detected no triphosphate in raw sewage entering the plant.
Jolley(1993)进行得一项研究中在溶解磷形态下molongolo污水处理厂（堪培拉，澳大利亚）未发现任何未经处理得污水中有三磷酸盐进入工厂。
