Management of the ground-water resources near Kualapuu on the island of Molokai, Hawaii, is hindered by the uncertainty in the vertical salinity structure in the aquifer. In the State of Hawaii, vertical profiles of ground-water salinity are commonly obtained from deep monitor wells, and these profiles are used to estimate the thicknesses of the freshwater part of the ground-water flow...

The endangered Maui Parrotbill (Pseudonestor xanthophrys) is an excavating, insectivorous Hawaiian honeycreeper endemic to the high elevation rain forests of east Maui, Hawaii. From March 1994 to June 1997, we studied various aspects of their breeding ecology. We color-banded 18 individuals, located and monitored 9 active nests, and took behavioral data during 440 hrs of nest observation...

The James Campbell National Wildlife Refuge occupies two lowland marsh and pond complexes on the northern coastal plain of Oahu: the mostly natural ponds and wetlands of the Punamano Unit and the constructed ponds of the Kii Unit. The U.S. Fish and Wildlife Service manages the Refuge primarily to protect and enhance habitat for four endangered species of Hawaiian waterbirds. Kii Unit is...

Ground-water and rainfall data for the period October 1987 through September 1997 from Tutuila and Aunuu, American Samoa, are plotted in time-series graphs and summarized. The data include pumpage and chloride concentrations from 53 production wells on Tutuila, including 5 new wells that were put into production between October 1996 and September 1997, 3 production wells on Aunuu, water...

Miconia calvescens (Melastomataceae), from the Neotropics, is a noxious forest weed in Hawaii. We evaluated an isolate of Colletotrichum gloeosporioides that causes leaf spots on Miconia spp. in Brazil for its potential in biological control. Hawaii has no native Melastomataceae genera but does have members of 12 introduced genera.

Variable circular-plot (VCP) counts are statistically more sound than point counts because they are adjusted for the probability of detecting birds at different distances and under different conditions. However, many ornithologists use point counts rather than VCP counts because they believe that assumptions of the VCP method are almost always violated, leading to poor results, and...

The following represents a new island record of Carposina nigronotata for Maui. Voucher specimens are housed in the Bishop Museum (BPBM), Honolulu.

The following contributions include new island records, new naturalized records, a range extension, and a name change of plants located on East Maui, Hawaii. Also included is a map of Maui showing locations of collections discussed in text. Voucher specimens are housed in the Bishop Museum, Honolulu (BISH).

We conducted a survey of the endangered Mariana Crow (Corvus kubaryi) population on Rota, Commonwealth of the Northern Mariana Islands, in October-November 1995 to provide current information on numbers and distribution of this species. To allow direct comparisons with a previous survey, we resurveyed transects established in 1982 using the same field methods and used identical analysis...

We conducted the first quantitative surveys of forest bird and bat populations on the uninhabited island of Sarigan, Commonwealth of the Northern Mariana Islands. Severe habitat degradation has occurred on Sarigan because of overgrazing by introduced goats and pigs. Planting of coconut palms (Cocos nucifera) for copra production has also eliminated much of the island’s native forest. We...

Kahili ginger (Hedychium gardnerianum) is an invasive weed in tropical forests in Hawaii and elsewhere. Bacterial wilt caused by the ginger strain of Ralstonia(=Pseudomonas) solanacearum systemically infects edible ginger (Zingiber officinale) and ornamental gingers (Hedychium spp.), causing wilt in infected plants. The suitability of R. solanacearum as a biological control agent for...
