Inbreeding Depression and Competition in the square-stemmed monkey-flower (Mimulus ringens)
… in models of mating system evolution. <italic>Mimulus ringens</italic> is a perennial plant native to North American wetlands and grows in competition with both an invasive plant, purple loosestrife: <italic>Lythrum salicaria</italic>) and its native congener, winged loosestrife: <italic>L. …

Transgenerational Plasticity is Sex-dependent and Persistent in Yellow Moneyflower (Mimulus guttatus)
… relatively few systems. Yellow monkeyflower (<em>Mimulus guttatus</em>) is known to exhibit transgenerational induction of increased glandular trichome production in response to simulated insect damage. Here we test for differences between maternal and paternal transmission of this response and …

DNA Methylation and Genetic Divergence Associated with an Inducible Defensive Response in Mimulus guttatus
… understood. Yellow Monkeyflower (formerly <em>Mimulus guttatus</em>; now <em>Erythranthe guttata</em>) is one such organism that can serve as a model to promote our understanding of these mechanisms due to its striking response to insect herbivory. Monkeyflower responds to leaf damage by …

Biosystematics of the annual species of the Mimulus guttatus species complex in British Columbia, Canada
The M. guttatus species complex consists of several morphologically and ecologically distinct taxa, which, for the most part, are able to intercross; this makes it both an evolutionarily fascinating group to study and a taxonomic nightmare. In this study I found that on one ecologically diverse …

Investigating the Genetic, Evolutionary, and Functional Mechanisms of Adaptations to Copper Mine Tailings in Mimulus guttatus
… tolerance in the common yellow monkeyflower, Mimulus guttatus, is a classic example of rapid adaptation in plants; however, little is yet known about the genetic, functional, and evolutionary mechanisms involved. How does excess copper cause toxicity in M. guttatus, and how do tolerant plants …

The Role of Polyploidy in Phenotypic and Genomic Evolution in the Shy Monkeyflower, <i>Mimulus sookensis<i>
… evolution? I use the shy monkeyflower, <italic>Mimulus sookensis</italic>, a tetraploid of hybrid origin between <italic>Mimulus guttatus</italic> and <italic>Mimulus nasutus</italic>, to address these focal questions. In order to develop a foundation to aid in interpretation of my findings, I …

The genetics of parallel evolution: a case study using thermal and non-thermal ecotypes of Mimulus guttatus from Yellowstone National Park
… transitions within the model plant genus Mimulus (monkeyflowers) provide a wonderful comparative context for investigating the predictability of the underlying mechanisms. Because multiple traits, with inherent differences in the underlying molecular pathways and potentially different …

Genetics Analysis of Standing Variation for Floral Morphology and Fitness Components in a Natural Population of Mimulus Guttatus (Common Monkeyflower)
… components in a natural population of annual Mimulus guttatus in the Oregon Cascades. Extensive inbreeding depression has been documented in this population for fertility and viability (Willis 1999 a,b), while previous biometric experiments have demonstrated that some of the floral variation …

Preferencia floral y correlaciones señal-recompensa en un sistema planta-polinizador
… fenotipos florales en una población de Mimulus luteus y la relación de tales preferencias con los niveles de recompensa asociados (néctar). M. luteus es una especie herbáceaque posee una guía de néctar ubicada en el lóbulo inferior de la corola (una mancha roja), aunque también es …

COMPARATIVE ECOPHYSIOLOGY OF NATIVE AND INVASIVE PLANTS ACROSS POPULATIONS, SPECIES, AND CONTINENTS
… tolerant perennials, and invasive populations of Mimulus guttatus in a greenhouse setting (22 total populations). I decomposed relative growth rates of each group into specific leaf area, photosynthetic rate, and leaf mass fraction to determine which trait contributed most to growth rate within …

A landscape approach to forecasting climate change impacts on geographic ranges and phenologies of plants in the Washington Cascades
As the pace of environmental change accelerates, biologists are transforming the discipline of ecology from a fundamentally descriptive science to one that can be used to generate skillful forecasts. Although important progress is being made, this work is stymied by (1) our limited understanding of …
