The Ecology of Adaptive Radiation
1. The origins of ecological diversity 2. Detecting adaptive radiation 3. The progress of adaptive radiation 4. The ecological theory of adaptive radiation 5. Divergent natural selection between… Expand
Wild Pollinators Enhance Fruit Set of Crops Regardless of Honey Bee Abundance
Honeybees Can't Do It Alone The majority of food crops require pollination to set fruit with the honeybee providing a pollination workhorse, with both feral and managed populations an integral… Expand
The Global Stock of Domesticated Honey Bees Is Growing Slower Than Agricultural Demand for Pollination
The prospect that a global pollination crisis currently threatens agricultural productivity has drawn intense recent interest among scientists, politicians, and the general public. To date, evidence… Expand
Expanding the limits of the pollen-limitation concept: effects of pollen quantity and quality.
Pollination commonly limits seed production, as addition of pollen to stigmas often increases fecundity. This response is usually interpreted as evidence that plants' stigmas receive too few pollen… Expand
Evolution and Development of Inflorescence Architectures
To understand the constraints on biological diversity, we analyzed how selection and development interact to control the evolution of inflorescences, the branching structures that bear flowers. We… Expand
Mating cost of large floral displays in hermaphrodite plants
HERMAPHRODITISM comprises outcrossing whenever the proximity of male and female organs allows self-fertilization1 and interference between sexual functions2. Many floral traits of animal-pollinated… Expand
Evolutionary Options for Maximizing Pollen Dispersal of Animal-Pollinated Plants
On the average, nectar-collecting bumble bees deposited 0.6% of the pollen removed from the flowers of Erythronium grandiflorum (Liliaceae) onto the stigmas of subsequently visited flowers. Because… Expand
The comparative biology of pollination and mating in flowering plants
The diversification of many flowering plant families has been attributed to adaptive radiation of pollination and mating systems accompanying changes in ecology and life history. Reproductive traits… Expand
Darwin's beautiful contrivances: evolutionary and functional evidence for floral adaptation.
Although not 'a professed botanist', Charles Darwin made seminal contributions to understanding of floral and inflorescence function while seeking evidence of adaptation by natural selection. This… Expand
Pollen Dispersal and Mating Patterns in Animal-Pollinated Plants
Immobility complicates mating by angiosperms because the transfer of male gametes between individuals requires pollen vectors. Although abiotic and biotic vectors can transport pollen considerable… Expand
