A comparison of levels of genetic polymorphism and self-compatibility in geographically restricted and widespread plant congeners
TL;DR: This work compared published data on electrophoretically detectable genetic variation and breeding systems for geographically restricted and widespread congeners in eleven genera to test evolutionary theory's predictions of low levels of genetic polymorphism and high levels of self-compatibility in plant species with small ranges and few individuals.
Journal ArticleDOI
New frontiers in competition for pollination.
Randall J. Mitchell,Rebecca J. Flanagan,Beverly J. Brown,Nickolas M. Waser,Nickolas M. Waser,Jeffrey D. Karron +5 more
TL;DR: A conceptual framework is presented that incorporates many aspects of competition for pollination, involving both the quantity and quality of pollination services, and both female and male sex functions of flowers, and how competition might affect plant mating systems, overall reproductive success and multi-species interactions.
Journal ArticleDOI
The influence of Mimulus ringens floral display size on pollinator visitation patterns
TL;DR: The three most abundant pollinator species differed significantly in behaviours that could influence plant mating patterns, including number of flowers probed per plant; interplant movement distances; and grooming.
Journal ArticleDOI
Ecology and evolution of plant–pollinator interactions
TL;DR: This Viewpoint paper highlights the application of ecological and evolutionary approaches to two themes in pollination biology: (1) links between pollinator behaviour and plant mating systems, and (2) generalization and specialization inpollination systems.
Journal ArticleDOI
The influence of population density on outcrossing rates in Mimulus ringens
TL;DR: The influence of population density on pollinator movements and outcrossing rates was studied in experimental arrays of Mimulus ringens, a wetland perennial species with a mixed-mating system, and ecological and demographic factors, such as population density, can significantly influence levels of inbreeding.
