The Ecology of Adaptive Radiation
TLDR
This chapter discusses the origins of ecological diversity and the ecological basis of speciation, as well as the progress of adaptive radiation and its role in ecology.
Wild Pollinators Enhance Fruit Set of Crops Regardless of Honey Bee Abundance
TLDR
Overall, wild insects pollinated crops more effectively; an increase in wild insect visitation enhanced fruit set by twice as much as an equivalent increase in honey bee visitation.
The Global Stock of Domesticated Honey Bees Is Growing Slower Than Agricultural Demand for Pollination
TLDR
Although the primary cause of the accelerating increase of the pollinator dependence of commercial agriculture seems to be economic and political and not biological, the rapid expansion of cultivation of many pollinator-dependent crops has the potential to trigger future pollination problems for both these crops and native species in neighboring areas.
Expanding the limits of the pollen-limitation concept: effects of pollen quantity and quality.
TLDR
This work explores both aspects of pollen limitation theoretically with a dose-response model that incorporates a saturating negative-exponential relation of seed production to pollen receipt and considers the influences on quantity and quality limitation, which reveals that quantity limitation probably occurs much less often than has been inferred from pollen-supplementation experiments.
Evolution and Development of Inflorescence Architectures
TLDR
This work shows that a single developmental model accounts for the restricted range of inflorescence types observed in nature and that this model is supported by molecular genetic studies, and predicts associations between inflorescence architecture, climate, and life history.
Mating cost of large floral displays in hermaphrodite plants
TLDR
Traditional interpretations of floral design and display are proposed to recognize their roles in reducing geitonogamous pollen discounting, which is observed to predict higher selfing and lower outcrossed siring success for larger inflorescences.
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
The comparative biology of pollination and mating in flowering plants
TLDR
This work addresses three topics in reproductive biology: floral allocation strategies, mating systems and life history, and the origin of complex reproductive syndromes using various comparative methods.
Morphology as a Predictor of Flower Choice by Bumble Bees
TLDR
Morphological differences between bees were associated with use of different plant species; however, the role of bee morphology in flower choice was most evident when preferred plant species bloomed abundantly.
Darwin's beautiful contrivances: evolutionary and functional evidence for floral adaptation.
TLDR
A contrast between the inconsistent occurrence of phenotypic selection and convincing experimental and comparative evidence that floral traits are adaptations is revealed and suggests that the tempo of creative selection varies.
