- An experimental test of the adaptive evolution of phototropins: blue-light photoreceptors controlling phototropism in Arabidopsis thalianaCandace Galen
Division of Biological Sciences, University of Missouri, Columbia, Missouri 65211 7400 USA
Evolution 58:515-23. 2004..Results show that phototropin-modulated pathways are adaptive and that their evolution has involved functional specialization. However, mechanism(s) of selection on these pathways remain a mystery...
- Catching ants with honey: an experimental test of distraction and satiation as alternative modes of escape from flower-damaging antsCandace Galen
Division of Biological Sciences, University of Missouri, 105 Tucker Hall, Columbia, MO 65211 7400, USA
Oecologia 144:80-7. 2005..Results do not support the idea that EFN evolve to reduce flower visitation by ants, but show instead that nectar in surplus flowers can satiate ants and reduce their negative impacts on flower function and integrity...
- Down the tube: pollinators, predators, and the evolution of flower shape in the alpine skypilot, Polemonium viscosumC Galen
Division of Biological Sciences, University of Missouri, Columbia 65211, USA
Evolution 55:1963-71. 2001..However, in the tundra, where bumblebees account for nearly all pollination, the model predicts that tubular flowers should always confer a fitness disadvantage...
- Solar furnaces or swamp coolers: costs and benefits of water use by solar-tracking flowers of the alpine snow buttercup, Ranunculus adoneusCandace Galen
Division of Biological Sciences, University of Missouri, Columbia, MO 65211 7400, USA
Oecologia 148:195-201. 2006..Plants with solar-tracking flowers may tolerate hotter conditions if soil moisture is plentiful, but not under drought...
- Density-dependent effects of ants on selection for bumble bee pollination in Polemonium viscosumCandace Galen
Division of Biological Sciences, University of Missouri, Columbia, Missouri 65211 7400, USA
Ecology 88:1202-9. 2007..Although high cheater abundance reduces the fitness returns of bumble bee pollination, it does not completely eliminate selection for bumble bee attraction in P. viscosum...
- A comparison of phenotypic plasticity in the native dandelion Taraxacum ceratophorum and its invasive congener T. officinaleMarcus T Brock
Division of Biological Sciences, University of Missouri, Columbia, Missouri 65211, USA
New Phytol 166:173-83. 2005..officinale within open and vegetated habitats. In contrast to the idea that plasticity promotes invasiveness, results suggest that the lack of plasticity in dispersal-related traits enhances the colonization potential of T. officinale...
- Functional ecology of a blue light photoreceptor: effects of phototropin-1 on root growth enhance drought tolerance in Arabidopsis thalianaCandace Galen
Division of Biological Sciences, University of Missouri Columbia, Columbia, MO 65211 7400, USA
New Phytol 173:91-9. 2007..Results indicate that phototropin-1 enhances performance under drought by mediating plastic increases in root growth efficiency near the soil surface...
- Ecophysiology of first and second generation hybrids in a natural plant hybrid zoneDiane R Campbell
Department of Ecology and Evolutionary Biology, University of California, Irvine, CA 92697, USA
Oecologia 144:214-25. 2005..Results indicate heterosis for water use efficiency, with no hybrid breakdown. Heterosis in WUE may help to explain the relatively high survival of both reciprocal F1 hybrids in dry sites within the natural hybrid zone...
- Stage-dependent patterns of drought tolerance and gas exchange vary between sexes in the alpine willow, Salix glaucaLeah S Dudley
Institute of Ecology and Biodiversity, Facultad de Ciencias, University of Chile, Santiago, Chile
