Costs of plasticity in foraging characteristics of the clonal plant Ranunculus reptans.
In clonal plants, evolution of plastic foraging by increased lengths of leaves and internodes under unfavourable conditions may be constrained by costs and limits of plasticity. We studied costs and limits of plasticity in foraging characteristics in 102 genotypes of the stoloniferous herb Ranunculus reptans. We grew three replicates of each genotype with and three without competition by the na...
متن کاملSelection on phenotypic plasticity of morphological traits in response to flooding and competition in the clonal shore plant Ranunculus reptans.
Adaptive evolution of phenotypic plasticity requires that plastic genotypes have the highest global fitness. We studied selection by spatial heterogeneity of interspecific competition and flooding, and by temporal heterogeneity of flooding on morphological plasticity of 52 genotypes of the clonal shore plant Ranunculus reptans. Competition reduced clone size, rosette size, leaf length and stolo...
متن کاملLocal adaptation of the clonal plant Ranunculus reptans to flooding along a small-scale gradient
1 Plant species are known to segregate along small-scale flooding gradients. We tested whether differences in flooding duration can also result in genetic differentiation in the clonal species Ranuneu/us replans, which naturally grows in both a lakeside microhabi tat and a landside microhabitat with shorter periods of flooding. 2 We compared traits related to fitness, and clonal life-history tr...
متن کاملRoot Foraging Increases Performance of the Clonal Plant Potentilla reptans in Heterogeneous Nutrient Environments
BACKGROUND Plastic root-foraging responses have been widely recognized as an important strategy for plants to explore heterogeneously distributed resources. However, the benefits and costs of root foraging have received little attention. METHODOLOGY/PRINCIPAL FINDINGS In a greenhouse experiment, we grew pairs of connected ramets of 22 genotypes of the stoloniferous plant Potentilla reptans in...
متن کاملRAPD variation among and within small and large populations of the rare clonal plant Ranunculus reptans (Ranunculaceae).
In the pre-alpine region of Europe numbers and sizes of populations of the clonal lake shore plant Ranunculus reptans have declined because of the regulation of lake water levels. We investigated genetic variation among and within 17 populations of different size (cover 1-10 000 m) in R. reptans with RAPD (random amplified polymorphic DNA) profiles. We sampled 127 rosettes in 14 populations at ...
