Snaring to control feral pigs sus scrofa in a remote Hawaiian rain forest Snaring to control feral pigs sus scrofa in a remote Hawaiian rain forest
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...

Status and population trends of Hawaii's native waterbirds, 1977-1987 Status and population trends of Hawaii's native waterbirds, 1977-1987
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...

Trophic interactions and direct physical effects control phytoplankton biomass and production in an estuary Trophic interactions and direct physical effects control phytoplankton biomass and production in an estuary
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...
