Using population genetic tools to develop a control strategy for feral cats (Felis catus) in Hawai'i.
The population genetics of feral cats on Hawai’i Island was studied by microsatellite analysis to evaluate genetic diversity and population structure, assess gene flow and connectivity among three populations, identify potential source populations, characterise population dynamics, and evaluate sex-biased dispersal.

Availability of food resources, distribution of invasive species, and conservation of a Hawaiian bird along a gradient of elevation
Aim We evaluated how an elevation gradient affects: (1) the availability of food required by a specialist seed-eater, Loxioides bailleui Oustalet (Drepanidinae), or palila, and hence the distributionExpand
Evidence of Feline Immunodeficiency Virus, Feline Leukemia Virus, and Toxoplasma gondii in Feral Cats on Mauna Kea, Hawaii
Prevalence to feline immunodeficiency virus antibodies, feline leukemia virus antigen, and Toxoplasma gondii antibodies in feral cats on Mauna Kea Hawaii from April 2002 to May 2004 is determined. Expand
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 areExpand
Survival of Feral Cats, Felis catus (Carnivora: Felidae), on Mauna Kea, Hawai'i, Based on Tooth Cementum Lines1
This work constructed the age distribution and estimated survival of feral cats in a remote area of Hawai'i Island using cementum lines present in lower canine teeth, and suggests annual cementum line formation. Expand
Trail Pheromone Disruption of Argentine Ant Trail Formation and Foraging
The success of these trail pheromone disruption trials in a natural ecosystem highlights the potential of this method for control of invasive ant species in this and other environments. Expand
Seed Chemistry of Sophora chrysophylla (Mamane) in Relation to Diet of Specialist Avian Seed Predator Loxioides bailleui (Palila) in Hawaii
The data suggest that palila have evolved tolerance to high levels of alkaloids and that they forage upon embryos primarily because of their availability in the habitat and high nutritional reward, and that Cydia are used by palila because they are readily accessible, nontoxic, and nutritious.

Alien dominance of the parasitoid wasp community along an elevation gradient on Hawai’i Island
The results support previous data indicating that alien parasitoids have deeply penetrated native forest habitats and may have substantial impacts on Hawaiian ecosystems. Expand
Forest climatology near the tree line in Hawai'i
Abstract One year of climatological measurements in a high elevation forest on the island of Hawai'i are analyzed to partially characterize the habitat of the palila bird, an endangered HawaiianExpand
