Conservation status and recovery strategies for endemic Hawaiian birds
Populations of endemic Hawaiian birds declined catastrophically following the colonization of the islands by Polynesians and later cultures. Extinction is still occurring, and recovery programs are urgently needed to prevent the disappearance of many other species. Programs to recover the endemic avifauna incorporate a variety of conceptual and practical approaches that are constrained by biologic

Serological responses and immunity to superinfection with avian malaria in experimentally-infected Hawaii Amakihi
Six of seven Hawaii Amakihi (Hemignathus virens) with chronic malarial infections had no increases in peripheral parasitemia, declines in food consumption, or loss of body weight when rechallenged with the homologous isolate of Plasmodium relictum 61 to 62 days after initial infection. Five uninfected control amakihi exposed at the same time to infective mosquito bites developed acute infections w

Drepanidine movements in relation to food availability in subalpine woodland on Mauna Kea, Hawai'i
Flowers of the mamane tree (Sophoru chrysophylla) are the primary nectar source for Hawaiian honeycreepers in subalpine woodland on Mauna Kea Volcano on the island of Hawai‘i. Mamane seeds are the primary food resource of the endangered Palila (Loxioides bailleui), which is now restricted to subalpine woodland on Mauna Kea. The objectives of this study were to determine the patterns and relative s

Pathogenicity, serological responses, and diagnosis of experimental and natural malarial infections in native Hawaiian thrushes
Omao (Myadestes obscurus) from the Hawaiian Islands typically have very low prevalences of infection with avian malaria (Plasmodium relictum) and it is not clear whether they share the same high susceptibility to this parasite that has been documented in native Hawaiian honeycreepers. We exposed four captive Omao to single infective mosquito bites and measured parasitemia, serological responses, a

Seedling mortality in Hawaiian rain forest: The role of small-scale physical disturbance
Most montane rain forests on the island of Hawaii consist of a closed canopy formed by Cibotium spp. tree ferns beneath an open canopy of emergent Metrosideros polymorpha trees. We used artificial seedlings to assess the extent to which physical disturbance caused by the senescing fronds of tree ferns and the activities of feral pigs might limit tree regeneration. Artificial seedlings were establi

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 incl

Population status of the Tinian Monarch (Monarcha takatsukasae) on Tinian, Commonwealth of the Northern Mariana Islands
We conducted surveys to evaluate the current population status of the Tinian Monarch (Monarcha takatsukasae), an insectivorous forest bird restricted to the island of Tinian, Commonwealth of the Northern Mariana Islands. In 1996, we recounted transects surveyed in 1982 and used the same analysis procedure to compare 1982 and 1996 population estimates. The 1996 population estimate was 55,721 ± 3,84

Ranchers and biologists in Hawai‘i — Keeping a business strong and protecting native forests at Ulupalakua Ranch, Maui
The loss of ranchland to critical habitat has been a major concern to ranchers and other large landowners in recent years. On the island of Maui, a novel approach is in the works which seems to have merit both for conservation of endangered species and for helping a landowner ethically manage an ecologically sensitive area.

Food habits of introduced rodents in high-elevation shrubland of Haleakala National Park, Maui, Hawai'i
Mus musculus and Rattus rattus are ubiquitous consumers in the high-elevation shrubland of Haleakala National Park. Food habits of these two rodent species were determined from stomach samples obtained by snaptrapping along transects located at four different elevations during November 1984 and February, May, and August 1985. Mus musculus fed primarily on fruits, grass seeds, and arthropods. Rattu

Toward a global information system for invasive species
The growing frequency and impact of biological invasions worldwide threaten biodiversity, ecosystem functioning, resource availability, national economies, and human health (Ruesink et al. 1995, Simberloff 1996, Vitousek et al. 1997). Organisms are spreading into new regions at unprecedented rates. As a result, hundreds to thousands of nonindigenous species of invertebrates, vertebrates, plants, b

Notes on status and ecology of the endangered Hawaiian annual Awiwi, Centaurium sebaeoides (Gentianaceae)
The annual, endemic, coastal herb Centaurium sebaeoides is the only native Hawaiian species in the gentian family. The U.S. Fish and Wildlife Service listed it as Endangered under the Endangered Species Act on 29 October 1991. Before surveys reported here, the total population of this species statewide was estimated at 80-110 individuals in eight populations. During counts made in April and May 19
