  pages={57 - 59}
Pollination--insects and plants benefiting each other--is one of nature's more widespread examples of mutual adaptation. How did it evolve? In his commentary, Labandeira discusses research reported in the same issue by [Ren][1] on elongated mouthparts and other pollination-adapted features of Late Jurassic brachyceran flies. This new work adds substantially to our understanding of the lineages of these insects and also the evolution of angiosperms, the most common form of seed plant. [1… Expand
Generalist Pollen-Feeding Beetles during the Mid-Cretaceous
It is demonstrated how a gymnosperm to angiosperm plant-host shift occurred during the mid-Cretaceous, from a generalist pollen-feeding family of beetles, which served as a driving mechanism for the subsequent success of flowering plants. Expand
Pollination biology of basal angiosperms (ANITA grade).
It is hypothesized that large flowers in Nymphaeaceae are the result of the interaction of heat, floral odors, and colored tepals to trap insects to increase fitness. Expand
Generalist flowers, biodiversity and florivory: implications for angiosperm origins
From the perspective of a floral morphologist, what a generalist flower is and how archaic angiosperms are characterized by this flower type are discussed. Expand
Flies and flowers: taxonomic diversity of anthophiles and pollinators
Abstract The Diptera are the second most important order among flower-visiting (anthophilous) and flower-pollinating insects worldwide. Their taxonomic diversity ranges from Nematocera to Brachycera,Expand
New Perspectives on the Pollination Biology of Basal Angiosperms
Coleoptera and Diptera are the primary pollinators of extant basal angiosperms (wind pollination is rare); lineages of these insects were established by the Late Jurassic. Contemporary examples ofExpand
How many species of arthropods visit flowers?
An overview of the taxonomic range of flower-visiting invertebrates is presented and it is speculated, based on reviewing the literature and discussions with experts, that ~30 % of arthropod species may regularly utilise flowers to feed, find a mate, or acquire other resources. Expand
A review of brood-site pollination mutualism: plants providing breeding sites for their pollinators

Abstract In this paper, I review pollination systems in which plants provide breeding sites as a reward for pollination. I divide the pollinators into three groups based upon ovipositing sites andExpand
Cycads: their evolution, toxins, herbivores and insect pollinators
New results on the uptake and storage of the main toxin, cycasin, of the Mexican cycad Zamia furfuracea by its pollinator, the weevil Rhopalotria mollis, and by a specialist herbivore of Zamia integrifolia, the aposematic Atala butterfly Eumaeus atala are added. Expand
The Pollination of Mid Mesozoic Seed Plants and the Early History of Long-proboscid Insects1,2,3
Evidence for pollination includes the entomophilous structure and size of pollen found on insect and plant contact surfaces and in insect guts, nutritional levels of modern pollination drop fluids similar to angiosperm nectar for supporting metabolically high activity levels of aerially active insects, and plant-host outcrossing. Expand
Convergent evolution and adaptive radiation of beetle-pollinated angiosperms
The floras of Australia and western North America suggest that mutualistic interactions between beetles and flowers has been a continuous and labile trend in angiosperms with novel interactions evolving through the Tertiary. Expand


Natural history of pollination
The methods by which pollen reaches the female flower, enabling fertilization and seed production to take place, include some of the most varied and fascinating mechanisms in the natural world. Expand
Flower-associated brachycera flies as fossil evidence for jurassic angiosperm origins

Functional morphology and comparison with modern confamilial taxa show that the orthorrhaphous Brachycera were some of the most ancient pollinators, and imply that angiosperms originated during the Late Jurassic and were represented by at least two floral types. Expand
Pollen in the guts of Permian insects: first evidence of pollinivory and its evolutionary significance
It is suggested that the peculiar taeniate pollen of worldwide distribution in the Permian might simultaneously evolve in several groups of Paleozoic seed plants in relation to pollinivory that, by altering the rnicropyle load and thereby the pollen/ovule ratio, could also affect ovuliferous structures. Expand
Timing in the evolution of derived floral characters: upper cretaceous (turonian) taxa with tricolpate and tricolpate-derived pollen
New data on floral structure from the Turonian of the Atlantic Coastal Plain reveal a surprising diversity of floral characters in taxa bearing tricolpate and tricolporate-derived pollen, which suggest that rather specific modes of insect pollination already existed at 90 Ma. Expand
Floral evidence for Cretaceous chloranthoid angiosperms
The Cretaceous material clarifies the homologies of chloranthoid androecial structures and provides an improved basis for interpreting the pollination biology in this enigmatic group of early angiosperms. Expand
The origin and early diversification of angiosperms
New palaeobotanical discoveries and phylogenetic analyses of morphological and molecular data have clarified the initial phases of this radiation and changed the perspective on early angiosperm evolution, though important issues remain unresolved. Expand
The Role of Beetles in the Pollination of Zamia furfuracea L. fil. (Zamiaceae)
Experimental evidence is presented supporting the hypothesis that snout weevils may be facultative pollinators of Z. furfuracea and circumstantial evidence that some genera and species of cycads may be insect pollinated is presented. Expand
Keys to the Evolution of Diptera: Role of Homoptera
The hypothesis that Diptera originally depended on honeydew explains their “dancing” behavior; their attraction to small, shiny objects; the presence of sugar receptors on their tarsi; and various basic, primitive differences between Diptera and other orders of Neoptera. Expand
Coprolites as evidence for plant–animal interaction in Siluro–Devonian terrestrial ecosystems
The discovery of coprolites in Upper Silurian and Lower Devonian rocks from the Welsh Borderland demonstrate the cycling of primary productivity in early terrestrial ecosystems. Expand
Pollination of endangered Cuban cycad Microcycas calocoma (Miq.) A.DC.
Observations indicate that natural regeneration in the field of the cycad Microcycas calocoma (Miq.) A.DC. is extremely low, and has been so since early this century. It appears that populations ofExpand
