| ontogenetic modulation of branch size, shape, and biomechanics produces diversity across habitats in the bursera simaruba clade of tropical trees. | organismal size and shape inseparably interact with tissue biomechanical properties. it is therefore essential to understand how size, shape, and biomechanics interact in ontogeny to produce morphological diversity. we estimated within species branch length-diameter allometries and reconstructed the rates of ontogenetic change along the stem in mechanical properties across the simaruba clade in the tropical tree genus bursera, measuring 376 segments from 97 branches in nine species in neotropica ... | 2013 | 22947317 |
