Journal ArticleDOI
Pollen-ovule ratios: a conservative indicator of breeding systems in flowering plants
TL;DR: The overall objective is to show that PIO's reflect the likelihood of sufficient pollen grains reaching each stigma to result in maximum seed set and suggest that PI O's are integrated with other facets of a plant's breeding system.
Journal ArticleDOI
Community Organization Among Neotropical Nectar-Feeding Birds
TL;DR: This work distinguishes five types of fiowers relative to hummingbird foraging, and defines six community roles for hummingbirds in exploitation of various flower types, and points out the many parallels that exist with other consumer groups.
Journal ArticleDOI
Synergy between visual and olfactory cues in nectar feeding by naı̈ve hawkmoths, Manduca sexta
Robert A. Raguso,Mark A. Willis +1 more
TL;DR: Wild M. sexta in this study did not show generalized feeding responses to natural or artificial flowers with single sensory stimuli; like naive laboratory-reared moths, they required a combination of visual and olfactory cues.
Book ChapterDOI
The Origin of Isolating Mechanisms in Flowering Plants
TL;DR: The fact that biotically sympatric populations which differ in adaptive mode almost invariably maintain their identity is prima facie evidence for their genetic isolation.
Journal ArticleDOI
Electroantennogram responses ofHyles lineata (Sphingidae: Lepidoptera) to volatile compounds fromClarkia breweri (Onagraceae) and other moth-pollinated flowers
TL;DR: H. lineata's olfactory sensitivity to diverse volatile compounds across a range of doses/concentrations suggests that a broad array of volatiles could function as floral attractants for foraging hawkmoths.
