Himalayan-Tibetan plateau uplift drives divergence of polyploid poppies: Meconopsis Viguier (Papaveraceae).

Meconopsis Viguier (Papaveraceae) is an iconic genus of alpine forbs that includes medicinal and ornamental species. This study extends previous phylogenetic analyses of Meconopsis, using ITS sequences representing all the major Meconopsis clades. Phenotypic traits are also analysed for all described species.

Combined effects of two arthropod herbivores and water stress on growth of Hypericum species.

The interaction between physiological stress and arthropod herbivory was studied using two perennial species of Hypericum. Seedlings of H. perforatum, a herb introduced to Australia and weedy in places, and H.

Factors affecting survival of tree seedlings in North Queensland rainforests.

Seedlings of six species of rainforest trees with widely constrasting ecology and seed morphology were transplanted at 3 weeks of age into tree-fall gaps and the shaded understoreys at two rainforest sites (Curtain Fig and Lamins Hill) on the Atherton Tableland, North Queensland, Australia. In each forest habitat, half of the transplanted seedlings were protected from vertebrates by means of wire cages, and survival was monitored over 16 months. The main objective was to estimate the extent to which independent variables (forest, habitat, protection from vertebrates, and species) contribute to explaining survival differences among the seedlings.
