nonconformance of standard metabolic rate with body mass in hawaiian honeycreepers.	among four species of hawaiian honeycreepers, three from hawaii (vestiaria coccinea, 15.0 g; himatione sanguinea, 12.9 g; loxops virens, 10.7 g) and one from kauai (loxops parva, 7.9 g), standard metabolic rate (in ml o2/g·h) was positively related to body mass, the opposite of that predicted by conventional endothermic allometry. smr of v. coccinea conformed to the predicted value, but in the remaining species was progressively reduced below expected levels as body mass decreased. all four spec ...	1981	28309993
characterization of poxviruses from forest birds in hawaii.	two strains of avian pox viruses were isolated from cutaneous lesions in hawaiian crows (corvus hawaiiensis) examined in 1994 and a third from a biopsy obtained in 1992 from an infected bird of the apapane species (himatione sanguinea) by inoculation of the chorioallantoic membranes (cam) of developing chicken embryos. the resulting proliferative cam lesions contained eosinophilic cytoplasmic inclusion bodies characteristic of pox virus infection. the pathogenicity of these three viruses in dome ...	2000	10813603
genetic structure and evolved malaria resistance in hawaiian honeycreepers.	infectious diseases now threaten wildlife populations worldwide but population recovery following local extinction has rarely been observed. in such a case, do resistant individuals recolonize from a central remnant population, or do they spread from small, perhaps overlooked, populations of resistant individuals? introduced avian malaria (plasmodium relictum) has devastated low-elevation populations of native birds in hawaii, but at least one species (hawaii amakihi, hemignathus virens) that wa ...	2007	17944845
prevalence and distribution of pox-like lesions, avian malaria, and mosquito vectors in kipahulu valley, haleakala national park, hawai'i, usa.	we determined prevalence and altitudinal distribution of introduced avian malarial infections (plasmodium relictum) and pox-like lesions (avipoxvirus) in forest birds from kipahulu valley, haleakalā national park, on the island of maui, and we identified primary larval habitat for the mosquito vector of this disease. this intensively managed wilderness area and scientific reserve is one of the most pristine areas of native forest remaining in the state of hawai'i, and it will become increasingly ...	2007	17984251
genetic structure along an elevational gradient in hawaiian honeycreepers reveals contrasting evolutionary responses to avian malaria.	the hawaiian honeycreepers (drepanidinae) are one of the best-known examples of an adaptive radiation, but their persistence today is threatened by the introduction of exotic pathogens and their vector, the mosquito culex quinquefasciatus. historically, species such as the amakihi (hemignathus virens), the apapane (himatione sanguinea), and the iiwi (vestiaria coccinea) were found from the coastal lowlands to the high elevation forests, but by the late 1800's they had become extremely rare in ha ...	2008	19014596
next-generation sequencing reveals cryptic mtdna diversity of plasmodium relictum in the hawaiian islands.	next-generation 454 sequencing techniques were used to re-examine diversity of mitochondrial cytochrome b lineages of avian malaria (plasmodium relictum) in hawaii. we document a minimum of 23 variant lineages of the parasite based on single nucleotide transitional changes, in addition to the previously reported single lineage (grw4). a new, publicly available portal (integroomer) was developed for initial parsing of 454 datasets. mean variant prevalence and frequency was higher in low elevation ...	2013	23953131
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
stable isotope analysis of multiple tissues from hawaiian honeycreepers indicates elevational movement.	we have limited knowledge of the patterns, causes, and prevalence of elevational migration despite observations of seasonal movements of animals along elevational gradients in montane systems worldwide. while a third of extant hawaiian landbird species are estimated to be elevational migrants this assumption is based primarily on early naturalist's observations with limited empirical evidence. in this study, we compared stable hydrogen isotopes (δ2h) of metabolically inert (feathers) and active ...	2020	32667954
