The red-flowered ecotype (panel B) is pollinated primarily by hummingbirds, while the yellow ecotype is pollinated by hawkmoths (D). These two taxa are non-randomly distributed across geographic space, with the red ecotype found in coastal regions of southern California (A), while the yellow-flowered ecotype is found further inland (C). https://images.squarespace-cdn.com/content/v1/5294186fe4b006d906121359/1568650810646-LH0DFQD2GSXAZPKWH0WV/ringens.png Research Cryptic life history diversity in M. ringens. A) A series of 9 populations spanning a wide range of latitude are represented by populations A-I. Variation in response to flowering time and population genomic structure (STRUCTURE plot in panel B and PCA in panel C) suggest that populations F and I are an ‘annual-like’ transition in life history from the typically perennial species. https://images.squarespace-cdn.com/content/v1/5294186fe4b006d906121359/1568651223119-ZJSHXKHJGGNWQKTMOUHC/fig5_v1.png Research Illustration of the developmental shift in phototropism that results in hyper-reduced seed dispersal in M. norrisii. The ‘before’ image precedes application of unidirectional blue-enriched light. In the ‘after’ image, flowers orient positively toward the light, while fruits (circled) actively move away from it. https://images.squarespace-cdn.com/content/v1/5294186fe4b006d906121359/1568649723679-GOXY0VQFVJ4SUXBJSS8X/fig1_v3_small.png Research A sampling of the tremendous diversity found in the genus Mimulus. Top row are edaphic specialists; e.g. A) M. guttatus on copper mine tailings, B) M. douglasii on serpentine, C) M. norrisii on limestone. Mimulus can also be found across an astounding range of hydrological settings, spanning wetlands to deserts, e.g. D) M. lewisii along a creek in the Cascades, E) M. mohavensis outside of Barstow, CA in the Mojave Desert. Species can withstand vastly different temperature regimes, e.g. F) M. tricolor growing near sea level in a remnant vernal pool of the central valley, G) M. tilingii growing in the subalpine zone of the Sierra Nevada at over 3,000 meters elevation. Mimulus also exhibits an impressive assortment of growth forms, from tiny herbaceous annuals to large woody perennial shrubs, e.g. H) M. breweri, a diminutive self-fertilizing annual (quarter for scale), I) M. aurantiacus, a large woody shrub that is a dominant member of many chaparral communities.

Many species pairs in the genus exhibit preliminary indications of hybrid seed dysfunction (blue), and our current research examines the evolutionary rates of hybrid seed lethality evolution and the underlying genetic and developmental mechanisms. http://www.sobel-lab.com/join-the-lab daily 0.75 2019-09-17 http://www.sobel-lab.com/teaching daily 0.75 2019-09-16 http://www.sobel-lab.com/publications daily 0.75 2021-10-28
