This data publication contains information collected as part of a field, laboratory, and modeling effort aimed at uncovering ecological drivers of avian malaria transmission and impacts on Hawaiian honeycreepers across an altitudinal gradient on the eastern flank of Mauna Loa and Kilauea volcanoes. Forest bird banding data and blood samples for diagnosis of Plasmodium relictum, the agent responsible for avian malaria in Hawaii, were collected from 2001 - 2005 at nine sites ranging 25 to 1,800 m above sea level. This data file reports morphometric data, age, sex, molt status and diagnostic results for avian malaria from native and non-native forest birds that were captured with mist nets at the nine study sites. Related data describing site and sampling coordinate data, mosquito capture data, mosquito avian malaria infection data, and point-transect distance sampling data is available at https://doi.org/10.5066/P95LVJIC. This XML describes one tabular CSV file: Banding Diagnostics Merge Final.CSV.

This data publication contains data files collected as part of a field, laboratory, and modeling effort aimed at uncovering ecological drivers of avian malaria transmission and impacts on Hawaiian honeycreepers across an elevational gradient on the eastern flank of Mauna Loa and Kilauea volcanoes on Hawaii Island. From 2001-2004, mosquito and bird data were collected at nine sites ranging 25 to 1,800 m above sea level. This data publication includes site and sampling coordinate data, mosquito capture data, mosquito avian malaria infection data, and point-transect distance sampling data. Site coordinate data consists of GPS spatial location data of sampling points where mosquitoes were captured and birds were surveyed to estimate abundance, comprising 45 points per site at 100 m intervals along five transects spaced 200 m apart. Mosquito capture data consists of counts of mosquitoes captured per trap night during 4-9 trapping nights per site per month over the study period. Mosquito infection data comprises avian malaria diagnostic data for a subset of captured mosquitoes that were dissected and malaria infection determined by microscopic examination of mosquito midguts and salivary glands. Point-transect distance sampling data consists of quarterly bird survey data in which observers recorded the horizontal distance of each sampling point to birds detected by sight and sound during 8-minute counts.

This data publication contains information collected as part of a field and laboratory effort to determine prevalence of avian malaria (Plasmodium relictum) and pox-like lesions (Avipoxvirus spp.) in native and non-native forest birds on the northern, high elevation (>1500 m) slopes of Haleakala volcano on Maui during the last decade of the 20th century. Forest bird banding data and blood samples for diagnosis of Plasmodium relictum, the agent responsible for avian malaria in Hawaii, were collected in 1993 and again in 1996 at Hanawi Natural Area Reserve and Waikamoi Preserve. Both areas comprise critical habitat for several species of endangered forest birds including Akohekohe (Palmeria dolei), Kiwikiu (Pseudonestor xanthophrys) and Poouli (Melamprosops phaeosoma) which were still extant in the wild at the time of the study. This data file reports morphometric data, age, sex, molt status, lesion occurrence, and diagnostic results for avian malaria from native and non-native forest birds that were captured with mist nets at the two study sites.

Native and introduced forest birds were captured and then released across the Hawaiian Islands to acquire a blood sample for obtaining DNA and test for exposure to avian malaria (Plasmodium relictum). A total of 2,945 samples were collected and analyzed for avian malaria prevalence from 39 species captured at 66 sites from Kauai, Oahu, Molokai, Maui, and Hawaii islands.

This data release includes metadata and tabular data from a field study of avian diseases (malaria and pox virus) that threatened recovery of the last extant population of ‘Alalā (Corvus hawaiiensis) before it went extinct in the wild in the early part of the 21st century. The study focused on habitat occupied by the last remaining wild ‘Alalā and determined prevalence of avian malaria (Plasmodium relictum) in native and non-native forest bird reservoir hosts (Atkinson et al. 2005), oviposition trap captures of Culex quinquefasciatus (the primary vector of avian malaria and pox virus) and Aedes albopictus across an altitudinal gradient, prevalence of malaria within the vector population, wing lengths of Culex quinquefasciatus and Aedes albopictus at different elevations, primary larval habitats and abundance of those habitats across an altitudinal gradient, environmental factors (temperature, humidity and rainfall) that might affect vector distribution and longevity, details about reduction in larval habitat after management actions to drain feral pig damaged tree ferns (Cibotium spp), and pre- and post-treatment oviposition trap catches before and after habitat management.

It is unclear whether DNA (Deoxyribonucleic Acid) lysis buffers used for preservation of whole blood samples from Hawaiian forest birds cause denaturation and loss of antigen binding capability of antibody molecules. If their antigen binding capability is not affected, then the samples can be used in serological assays to provide an independent assessment of the accuracy of PCR (polymerase chain reaction) diagnostic tests for avian malaria. This data release consists of three tabular datasets of raw absorbance measurements that were collected with a BioRad Model 3550 ELISA (Enzyme linked Immunosorbant Assay) plate reader at a wavelength setting of 405 nm from serial dilutions of whole blood that were preserved with either PBS (phosphate buffered saline) or two different DNA lysis buffers and a single tabular dataset of Percent ELISA Values that were derived from the raw absorbance measurements. The whole blood was collected from uninfected Hawaii Amakihi and Hawaii Amakihi experimentally infected with Plasmodium relictum that were collected from Upper Waikea Forest Reserve on Hawaii Island.
