allopatric speciation
異斑點物種形成
sympatric speciation
同斑點物種形成
3) Geographic isolation may facilitate cryptic speciation of marine holoplankton.However,contribution of allopatric speciation is still questionable;
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;
Polyploidy is a mechanism often attributed to causing some speciation events in sympatry.
多倍性常被當作引起在同一地區並存的物種發生物種形成事件的一種機制。
This conclusion agress with the viewpoint that this species is on the speciation stage of migration towards north.
這一結論支持該種目前正處於向北遷移的分化階段的觀點。
First, there is speciation (species-splitting or cladogenesis), caused by geographical isolation or some other mechanism.
首先，因地理隔離或其它一些機制導致物種形成（物種分裂或系枝進化）。
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.
這一術語與發生在世系內的“前進演化”或“種族的進化”這些提法相牴觸。
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)進行得一項研究中在溶解磷形態下molongolo污水處理廠（堪培拉，澳大利亞）未發現任何未經處理得污水中有三磷酸鹽進入工廠。
