Objectives:
The main objective of this study is to investigate barriers to gene flow between species in the wildflower genus Mimulus. Using a published phylogeny of the genus, recently speciated sister species pairs were selected. For each of these pairs, all potential barriers to gene flow are being measured including: habitat isolation, temporal isolation, pollinator isolation, gametic isolation, and genetic incompatibility. A variety of techniques are being employed including field observation of flowering time and pollinators, geographic range documentation from field collections and herbaria records, and experimental hybridizations in the greenhouse. In addition, DNA is being extracted from leaf tissue to estimate genetic distance between species pairs and to study patterns of historical and ongoing gene flow between these close relatives.
