Zonal distribution of pelagic decapoda (crustacea) in the eastern North Atlantic and its relation to the physical oceanography

摘要: Abstract The day and night vertical distribution of pelagic decapods at six stations in the eastern North Atlantic on 20°W have been analysed using principal components analysis coupled with varimax rotation. species classified into fourteen faunal groups scores used to typify Zoogeographic migratory behaviour these groups. same method was classify samples it found that resulting zonation could be partly explained by classical picture oceanic circulation Atlantic. explanatory power this hypothesis quantified Procrustes explain about 50% sums-of-squares between correlation matrix.
