James D Jacobi
Specialty: A major focus of his research has been mapping the distribution of plant communities throughout the Islands initially utilizing photo interpretation and, more recently, digital image analysis.
Research Interests: Hawaiian species and ecosystem conservation; alien species impacts; vegetation ecology; plant community mapping; GIS applications for conservation; plant species and community modeling; vegetation monitoring; assessment of forest bird populations; bringing science to conservation planning.
Personal Interests: The conservation of Hawaiian biodiversity

Translocation of the Palila, an endangered Hawaiian honeycreeper
The Palila Loxioides bailleui is an endangered Hawaiian honeycreeper that is restricted to high-elevation dry woodlands on Mauna Kea volcano, Hawaii. Palila are absent or occur in small numbers throughout most of their historic range because of habitat loss, predation and avian disease. The Paula's habitat is regenerating as a result of feral ungulate control, but the species is likely to be slow

Hawaii's endemic birds
The endemic landbirds of Hawaii, particularly the Hawaiian honeycreepers, an endemic subfamily of the cardueline finches, are one of the world's most dramatic examples of adaptive radiation and speciation (see glossary) in island ecosystems (Freed et al. 1987; Scott et al. 1988). From what is believed to have been a single successful colonization of the Hawaiian Archipelago by an ancestral species

Identifying sex and age of akiapolaau
Methods for identifying the sex and age of the Akiapolaau (Hemignathus munroi), an endangered honeycreeper found only on the island of Hawaii, were developed by examination and measurement of 73 museum specimens and 24 live birds captured in mist nests. Akiapolaau probably undergo a single annual molt, with most birds molting between February and July. The mottled juvenal plumage is replaced by a

Identifying sex and age of apapane and iiwi on Hawaii
Methods to determine the sex and age of Apapane (Himatione sanguinea) and Iiwi (Vestiaria coccinea) were developed on the basis of 189 museum specimens and 91 live birds captured in mist nets on the Island of Hawaii (USA). Both species retain all juvenal primaries and some juvenal secondaries and body feathers after the first prebasic molt and attain full adult plumage after the second prebasic mo

Sex and age identification of palila
Methods to sex and age Palila (Loxioides bailleui), an endangered Hawaiian finch restricted to subalpine woodlands on Hawai'i, were identified on the basis of measurements and plumage characteristics of 17 museum specimens and 96 known-age, live Palila. Palila undergo a single annual molt during September-December following the breeding season. Presence of a complete or partial wingbar distinguish

Site tenacity of the endangered palila
Strong site tenacity might prevent Palila (Loxioides bailleui), an endangered Hawaiian honeycreeper, from repopulating favorable habitats in their former range. We used radio telemetry during the nonbreeding and breeding seasons to study movements and dispersal rates of 57 Palila. All Palila remained in the study area, and home range sizes and movement distances were small relative to the potentia

Annual variation in the distribution, abundance, and habitat response of the palila (Loxioides bailleui)
We studied the distribution, population size, and habitat response of the Palila (Loxioides bailleui) during the 1980-1984 nonbreeding seasons to infer factors that limit the population and to develop management strategies. Distribution was fairly constant from year to year. Palila were confined to the subalpine woodland on Mauna Kea on the island of Hawaii, occurred between 2,000 and 2,850 m elev
