| Resumen : | Morphometric analyses of 220 specimens of a characid, Bryconops sp. cf. melanurus, from
the Brazilian Pantanal were used to describenezuelaallometric growth in that species and determine whether
specimens from highland habitats were more streamlined than those from lowland habitats. Relative
warp analysis of 14 landmarks and principal component analysis of 28 interlandmark distances returned
complementary results. The increased streamlining of the highland specimens is highly consistent
with known inductive effects of high water velocity on fish phenotypes. Genetic differentiation and
inductive effects of temperature variation are also potential explanations of the observed phenotypic
differentiation. |
