Despite Hawaii's reputation as an extinction icon, significant biological resources remain, especially in watersheds, natural areas, and specialized edaphic sites (e.g., lava dry forest, coastal). While direct habitat destruction by humans continues, human-facilitated biological invaders are...

Efforts to restore highly degraded but biologically significant forests draw from a limited toolbox. With less than 10% of their former distribution remaining, Hawaiian dry forests, though critically endangered, remain important biological and cultural refugia. At restoration onset (1997),...

Analysis of long-term patterns of invasion can reveal the importance of abiotic factors in influencing invasion dynamics, and can help predict future patterns of spread. In the case of the invasive Argentine ant (Linepithema humile), most prior studies have investigated this species' limitations in ...

A study was carried out of the invasion of Miconia calvescens into the wet forests of the Society and Hawaiian Islands. This tree is potentially considered as the most invasive and damaging weed of rain forests of Pacific islands. In most conditions, it grows rapidly, tolerates shade, and produces...

Ring-necked pheasants (Phasianus colchicus) and chukar (Alectoris chukar) are the dominant avifauna in high altitude (2070-3000 m) shrubland of Haleakala National Park, Maui, Hawaii. Results are given of a study of the food habits, ecological niche and effects of these alien game birds on the...

Pitfall trapping and under-rock surveys were conducted in the high-altitude shrubland of Haleakala National Park, Maui, Hawaii, in 1985-86, to determine the effects of Iridomyrmex humilis (originally from Argentina) on the local arthropod fauna, which includes many locally endemic and rare species, ...

Cyathea cooperi, (widely planted in Hawaii and until recently identified as C. australis which is also present in botanical gardens in Hawaii) is now naturalized on the islands of Kauai, Oahu and Maui. Stand structure of C. cooperi was determined in April 1991 from measurements on 12 contiguous...

The feeding behaviour of adults of P. pensylvanica [Vespula pensylvanica] was studied in Hawaii in September 1986. The vespids were observed to collect honeydew produced by Pseudococcus nudus on Styphelia taneiameiae and their prey included Araneae (23.6%), Lepidoptera (22.3%), Homoptera (20.9%),...
