Abstract

Scanning electron micrographs of pollen adhering to head feathers from preserved museum specimens of extinct or endangered Hawaiian birds indicate that several now extinct species once pollinated the Hawaiian ieie vine, Freycinetia arborea Gaud. The extinction of these birds together with the 1929 introduction of the Japanese white-eye (Zosterops japonica) to Hawaii resulted in a change of pollinators for F. arborea. This methodology may prove useful in ecological studies of plant-animal relationships involving extinct or endangered animals. /// Микрофотографии пыльцы с головных перьев музейных экземпляров исчезнувших или находящихся под угрозой исчезновения птиц, сделанные на сканирующем электронном микроскопе, показывают, что несколько ныне исчезнувших видов когда-то опыливали гавйскую Freycinetia arborea Gaud. Исчезновение этих птиц, наряду с интродукцией в 1929 г. японского Zosterops japonica на Гавайи привело к изменению состава опылителей F. arborea. Этот метод может использоваться в экологических исследованиях взаимоотношений растение-животное, включая исчезнувшие лил находящиеся под угрозой исчезновения виды.
