Plant genotype and induced responses affect resistance to herbivores on evening primrose (Oenothera biennis)
1. Although both genotype and induced responses affect a plant’s resistance to herbivores, little is known about their relative and interactive effects. This study examined how plant genotype of a native plant (Oenothera biennis) and induced plant responses to herbivory affect resistance to, and interactions among, several herbivores. 2. In a field experiment, genetic and environmental variatio...
متن کاملPERMANENT GENETIC RESOURCES: Isolation and characterization of polymorphic microsatellite loci in common evening primrose (Oenothera biennis).
We developed nine polymorphic microsatellite loci for evening primrose (Oenothera biennis). These loci have two to 18 alleles per locus and observed heterozygosities ranging from 0 to 0.879 in a sample of 34 individuals. In a pattern consistent with the functionally asexual reproductive system of this species, 17/36 pairs of loci revealed significant linkage disequilibrium and three loci showed...
متن کاملGenotype-by-environment interactions leads to variable selection on life-history strategy in Common Evening Primrose (Oenothera biennis).
Monocarpic plant species, where reproduction is fatal, frequently exhibit variation in the length of their prereproductive period prior to flowering. If this life-history variation in flowering strategy has a genetic basis, genotype-by-environment interactions (G x E) may maintain phenotypic diversity in flowering strategy. The native monocarpic plant Common Evening Primrose (Oenothera biennis ...
متن کاملCovariation and composition of arthropod species across plant genotypes of evening primrose, Oenothera biennis
Genetic variation in plants has broad implications for both the ecology and evolution of species interactions. We addressed how a diverse community of arthropod species covary in abundance among plant genotypes of a native herbaceous plant (Oenothera biennis ), and if these effects scale-up to shape the composition, diversity, and total abundance of arthropods over the entire lifetime of plants...
متن کاملThe evolution of tolerance to deer herbivory: modifications caused by the abundance of insect herbivores.
Although recent evidence indicates that coevolutionary interactions between species often vary on a biogeographical scale, little consideration has been given to the processes responsible for producing this pattern. One potential explanation is that changes in the community composition alter the coevolutionary interactions between species, but little evidence exists regarding the occurrence of ...
