| latitudinal gradient in otolith shape among local populations of atlantic herring (clupea harengus l.) in norway. | otolith shape analysis of atlantic herring (clupea harengus) in norwegian waters shows significant differentiation among fjords and a latitudinal gradient along the coast where neighbouring populations are more similar to each other than to those sampled at larger distances. the otolith shape was obtained using quantitative shape analysis, the outlines were transformed with wavelet and analysed with multivariate methods. the observed morphological differences are likely to reflect environmental ... | 2015 | 26101885 |
