title = "Maintaining a happy face: Stable colour polymorphism in the spider theiridion grallator (Araneae, theridiidae)",
abstract = "Theridion grallator is a highly polymorphic spider endemic to the wet and mesic forests of the Hawaiian Islands. The frequencies of the two major morph classes, patterned and unpatterned abdomen, did not show significant spatial or temporal variation within undisturbed or disturbed areas on Maui. Similarly, morph frequencies did not vary significantly between undisturbed areas on three different islands. Estimates of spider migration suggest that gene flow is sufficient to account for the similarity in frequency within and between areas on Maui, but it is probably not sufficient to explain the similarity among islands. Fecundity did not differ between morphs. A significant inverse relationship between morph frequency and residence time in certain cases suggests that frequency-dependent selection, perhaps mediated by bird predation, may play a role in maintaining the polymorphism.",

note = "Funding Information: through the work of Sam Gon. It would have been impossible without an enormous amount of help from the Nature Conser-vancy of Hawaii: Rob Rydell encouraged the initial efforts; Alan Holt, Paul Higashino and Mark White allowed progress to continue throughout the year; the work on Molokai would have been impossible without the help of Ed Misaki. Dr Lloyd Loope and Art Medeiros (Haleakala National Park) gave immense support and encouragement throughout the study. Thanks also to Bill Mull for invaluable advice and discussion, to Geoff Oxford and Jay Rosenheim for useful comments on the first draft, and to John Bordley and the University of the South for use of computer equipment. Chris Parrish helped in completion of the study. The work was funded by Whitehall Foundation grant J86-47, with additional support from the Nature Conservancy of Hawaii, the National Park Service, and a Fujio Matsuda Scholar Award from the University of Hawaii Foundation.",
