| first report of an armillaria root disease pathogen, armillaria gallica, associated with several new hosts in hawaii. | the loss and decline of native tree species caused by invasive plant pathogens is a major threat to the endangered endemic forests of the hawaiian islands (3). thus, it is critical to characterize existing pathogens to evaluate potential invasiveness. in august 2005, rhizomorphs and mycelial bark fans of genet hi-4 were collected from dead/declining, mature trees of introduced monterey pine (pinus radiata) on the southern flank of mauna kea, hawaii (approximately 19°42'55″n, 155°26'48″w, elevati ... | 2010 | 30743375 |
| seed chemistry of sophora chrysophylla (mamane) in relation to diet of specialist avian seed predator loxioides bailleui (palila) in hawaii. | this study describes the chemical ecology of a tritrophic interaction among species endemic to the island of hawaii, usa: a tree (sophora chrysophylla: mamane), an endangered bird (loxioides bailleui; palila), and moth larvae (cydia spp.). palila and cydia both specialize on the seed embryos of mamane but avoid eating the seed coats. palila actively seek out and feed mamane embryos and cydia larvae to their nestlings. because mamane embryos contain potentially toxic levels of alkaloids, includin ... | 2002 | 12199503 |
| evaluation of pathogenicity of avian poxvirus isolates from endangered hawaiian wild birds in chickens. | pathogenicity of two avian poxviruses isolated from endangered hawaiian wild birds, the hawaiian goose and the palila, was compared with fowl poxvirus in chickens. immune responses were measured by elisa pre- and postimmunization with hawaiian poxviruses and after challenge with fowl poxvirus. both isolates from hawaiian birds developed only a localized lesion of short duration at the site of inoculation in specific-pathogen-free chickens and did not provide protection against subsequent challen ... | 2006 | 16863084 |
| genomic resources for the endangered hawaiian honeycreepers. | the hawaiian honeycreepers are an avian adaptive radiation containing many endangered and extinct species. they display a dramatic range of phenotypic variation and are a model system for studies of evolution, conservation, disease dynamics and population genetics. development of a genome-scale resources for this group would augment the quality of research focusing on hawaiian honeycreepers and facilitate comparative avian genomic research. | 2014 | 25496081 |
