The puaioihi (Myadestes palmeri) and the kamao (M. myadestinus) are endangered solitaires endemic to Kauai in the Hawaiian Islands and now restricted to the Alakai Swamp. The puaiohi has been rare historically with population estimates declining since the first population surveys 1968-73. Puaiohi were believed to be on the verge of extinction with population estimates less than 35 birds since 1981

Biological invasions are a widespread and significant component of human-caused global environmental change. The extent of invasions of oceanic islands, and their consequences for native biological diversity, have long been recognized. However, invasions of continental regions also are substantial. For example, more than 2,000 species of alien plants are established in the continental United State

Miconia calvescens (Melastomataceae), native to montane forests of the neotropics, has now invaded wet forests of both the Society and Hawaiian Islands. This tree, which grows up to 15 m tall, is potentially the most invasive and damaging weed of rainforests of Pacific islands. In moist conditions, it grows rapidly, tolerates shade, and produces abundant seed that is effectively dispersed by birds

The ‘I‘iwi is one of the most spectacular of extant Hawaiian birds, with vermilion plumage, black wings and tail, and long, decurved bill. In pre-European Hawai‘i, beautiful feather capes, sometimes containing hundreds of thousands of ‘I‘iwi feathers, were a symbol of power and prestige among native Hawaiians. The ‘I‘iwi is a bird of the Hawaiian forests. Its decurved bill seems well adapted to ex

The 'Apapane is the most abundant species of Hawaiian honeycreeper and is perhaps best known for its wide-ranging flights in search of localized blooms of ō'hi'a (Metrosideros polymorpha) flowers, its primary food source. 'Apapane are common in mesic and wet forests above 1,000 m elevation on the islands of Hawai'i, Maui, and Kaua'i; locally common at higher elevations on O'ahu; and rare or absent

Feral pig Sus scrofa control in Kipahulu Valley, a remote rain forest in Haleakala National Park, Maui, Hawaiian Islands, has been achieved with snares over a 45-month period. Initial pig densities in fenced management units of 6·2 km2 and 7·8 km2were estimated at 6 animals/km2 and 14·3 animals/km2 for the two units, based on population reconstruction from animals killed and aged. During the 45 mo

Status and population trends of Hawaiis ’ native waterbirds were examined from 1977 through 1987. Waterbird population fluctuations were analyzed in relation to rainfall and land use dynamics. Numbers of Hawaiian Duck (Koloa) (Anus wyvilliana) and Hawaiian Common Moorhen (Gallinula chloropus sandvicensis) appeared stable over time; however, surveys were limited. Increase in Black-crowned Night-Her

San Francisco Bay has recently been invaded by the suspension-feeding clam Potamocorbula amurensis. Previous work has shown that phytoplankton biomass in the upper estuary is low (2-3 mg Chl a m-3) during seasonal periods of high river flow and short residence time and it is usually high (peak >30 mg Chl a m-3) during the summer-autumn seasons of low river flow and long residence time. However sin
