THE MEASUREMENT OF SELECTION ON QUANTITATIVE TRAITS: BIASES DUE TO ENVIRONMENTAL COVARIANCES BETWEEN TRAITS AND FITNESS
  • M. Rausher

  • Evolution; international journal of organic…
  • 1 June 1992
The use of regression techniques for estimating the direction and magnitude of selection from measurements on phenotypes has become widespread in field studies. A potential problem with theseExpand

Evolutionary Transitions in Floral Color
  • M. Rausher

  • International Journal of Plant Sciences
  • 1 January 2008
The tremendous diversity in flower color among angiosperms implies that there have been numerous evolutionary transitions in this character. The conventional wisdom is that a large proportion ofExpand

VARIATION IN THE DEFENSE STRATEGIES OF PLANTS: ARE RESISTANCE AND TOLERANCE MUTUALLY EXCLUSIVE?
Plants can employ two general strategies to defend themselves against herbivory: they can either reduce the amount of damage they experience (resistance), or they can tolerate herbivore damage.Expand

Escape from adaptive conflict after duplication in an anthocyanin pathway gene
Gene duplications have been recognized as an important source of evolutionary innovation and adaptation since at least Haldane, and their varying fates may partly explain the vast disparity inExpand

EXPERIMENTAL MANIPULATION OF PUTATIVE SELECTIVE AGENTS PROVIDES EVIDENCE FOR THE ROLE OF NATURAL ENEMIES IN THE EVOLUTION OF PLANT DEFENSE
Although biologists have long assumed that plant resistance characters evolved under selection exerted by such natural enemies as herbivores and pathogens, experimental evidence for this assumptionExpand

Co-evolution and plant resistance to natural enemies
Co-evolution between plants and their natural enemies is generally believed to have generated much of the Earth's biological diversity. A process analogous to co-evolution occurs in agriculturalExpand

Genetic Constraints and Selection Acting on Tolerance to Herbivory in the Common Morning Glory Ipomoea purpurea
Tolerance to herbivory minimizes the effects of herbivory on plant fitness. In the presence of herbivores, maximal levels of tolerance may be expected to evolve. In many plant species, however,Expand

Tradeoff between resistance and tolerance to herbivore damage in a morning glory
MANY plant characters, including toxic secondary compounds, trichomes, spines and tough, nutrient-poor leaves have evolved at least in part as defences against pathogens and herbivores, includingExpand

PARALLEL EVOLUTION AT MULTIPLE LEVELS IN THE ORIGIN OF HUMMINGBIRD POLLINATED FLOWERS IN IPOMOEA
A transition in flower color accompanying a shift in pollinator guilds is a prominent and repeated adaptation in angiosperms. In many cases, shifts to similar pollinators are associated with similarExpand

Patterns of evolutionary rate variation among genes of the anthocyanin biosynthetic pathway.
The anthocyanin biosynthetic pathway is responsible for the production of anthocyanin pigments in plant tissues and shares a number of enzymes with other biochemical pathways. The six core structuralExpand
