The evolution of wind pollination in angiosperms
Theresa M. Culley* Stephen G. Weller Ann K. Sakai Dept of Ecology and Evolutionary Biology, University of California–Irvine, Irvine, CA 92697, USA. *e-mail: [email protected] Although much emphasis has been placed on specialist pollination systems, attention is shifting towards systems in which plants are visited by a variety of pollinators [1,2]. Until recently, examples of generalist pollinatio...

متن کاملCorrelations of Life Form, Pollination Mode and Sexual System in Aquatic Angiosperms
Aquatic plants are phylogenetically well dispersed across the angiosperms. Reproductive and other life-history traits of aquatic angiosperms are closely associated with specific growth forms. Hydrophilous pollination exhibits notable examples of convergent evolution in angiosperm reproductive structures, and hydrophiles exhibit great diversity in sexual system. In this study, we reconstructed a...
متن کاملA Phylogenetic Analysis of the Evolution of Wind Pollination in the Angiosperms
Wind pollination is predominantly a derived condition in angiosperms and is thought to evolve in response to ecological conditions that render animal pollination less advantageous. However, the specific ecological and evolutionary mechanisms responsible for transitions from animal to wind pollination are poorly understood in comparison with other major reproductive transitions in angiosperms, i...
متن کاملA probable pollination mode before angiosperms: Eurasian, long-proboscid scorpionflies.
The head and mouthpart structures of 11 species of Eurasian scorpionflies represent three extinct and closely related families during a 62-million-year interval from the late Middle Jurassic to the late Early Cretaceous. These taxa had elongate, siphonate (tubular) proboscides and fed on ovular secretions of extinct gymnosperms. Five potential ovulate host-plant taxa co-occur with these insects...
