  • Berger, Andrew J; Gressitt, J Linsley; Mueller-Dombois, Dieter (Island Ecosystems IRP, U.S. International Biological Program, 1970-12)
    The Hawaii subprogram of the U.S. Contribution to IBP was funded six months ago, in June 1970. It is one of three subprograms of the "Origin and Structure of Ecosystems Integrated Research Program" under the directorship ...
  • Mueller-Dombois, Dieter; Berger, Andrew J; Gressitt, J Linsley (Island Ecosystems IRP, U.S. International Biological Program, 1972-01)
    The Island Ecosystems Integrated Research Program (IRP) of the US Contribution to the International Biological Program (IBP) has been active for 18 months. The program is centered in Hawaii. The original name of the program, ...
  • Spatz, Gunter; Mueller-Dombois, Dieter (Island Ecosystems IRP, U.S. International Biological Program, 1972-02)
    Goats were introduced to the Hawaiian Islands nearly 200 years ago. They have become wild and today roam in many Hawaiian ecosystems with dry-season climates from the lowlands to the mountains. A quantitative analysis was ...
  • Mueller-Dombois, Dieter (Island Ecosystems IRP, U.S. International Biological Program, 1972-03)
    A bunch grass species (Andropogon virginicus) from the North American continent was introduced to the island of Oahu, Hawaii in 1932. The grass began to spread. Today it forms the dominant grass cover in the rain forest ...
  • Gressitt, J Linsley; Davis, Clifton J (Island Ecosystems IRP, U.S. International Biological Program, 1972-04)
    The cerambycid beetle borers play an important role in Hawaiian forests, both in the natural and disturbed environments. Their significance is enhanced by the disharmonic nature of the fauna, such as the lack of leaf beetles ...
  • MacMillen, Richard E (Island Ecosystems IRP, U.S. International Biological Program, 1972-08)
    Insular biotas have attracted considerable biological attention, and have been very important in the formulation of evolutionary thought and theory. Since Charles Darwin's visit to the Galapagos Islands and his description ...
  • Berger, Andrew J (Island Ecosystems IRP, U.S. International Biological Program, 1972-08)
    The dominant and subdominant plants are listed for 10 major vegetational and climatic areas within Volcanoes National Park. These areas are located at elevations between 1,400 and 10,000 feet. Information on the birds found ...
  • Steffan, Wallace A (Island Ecosystems IRP, U.S. International Biological Program, 1972-08)
    The seasonal fluctuations of Ctenosciara hawaiiensis (Hardy) populations in two different ecosystems at the same elevation on Mauna Loa on the island of Hawaii are compared and correlated with fluctuations in rainfall, ...
  • Corn, Carolyn (Island Ecosystems IRP, U.S. International Biological Program, 1972-08)
    Hawaiian Metrosideros seeds need 3 to 12 miles per hour wind velocity to become airborne, and can survive -30 deg C temperatures for at least 6 hours. They also survive sea water soaking for 30 days followed by an additional ...
  • Berger, Andrew J (Island Ecosystems IRP, U.S. International Biological Program, 1972-09)
    The Kilauea Forest Reserve is notable for the island of Hawaii because it provides habitat for at least nine species of endemic birds, of which six species are members of the Hawaiian Honeycreeper family (Drepanididae): ...
  • Smathers, Garrett A; Mueller-Dombois, Dieter (Island Ecosystems IRP, U.S. International Biological Program, 1972-09)
    A major volcanic eruption on the Island of Hawaii in December 1959 devastated one existing montane rain- and seasonal-forest covering an area of about 500 ha. The eruption resulted in a massive pahoehoe lava substrate on ...
  • Mueller-Dombois, Dieter; Spatz, Gunter (Island Ecosystems IRP, U.S. International Biological Program, 1972-10)
    The coastal lowland of Hawaii Volcanoes National Park, particularly its western part, is a concentration center of feral goats. Here, in a tropical seasonal climate, a widespread vegetation is an annual Eragrostis tenella ...
  • Mueller-Dombois, Dieter; Spatz, Gunter (Island Ecosystems IRP, U.S. International Biological Program, 1972-10)
    The study relates to an investigation of the vegetation around Kahe power station, a recently established electricity generating plant at Kahe Point on SW Oahu. A vegetation map was prepared from aerial photographs at ...
  • Spatz, Gunter; Mueller-Dombois, Dieter (Island Ecosystems IRP, U.S. International Biological Program, 1972-11)
    The influence of feral pigs on the composition of grassland communities on the east flank of Mauna Loa, Hawaii, was studied for the one year period from July, 1971, to August, 1972. Actual pig-disturbed areas as well as ...
  • Howarth, Francis G (Island Ecosystems IRP, U.S. International Biological Program, 1972-12)
    The Hawaiian Islands offer great potential for evolutionary research. The discovery of specialized cavernicoles among the adaptively radiating fauna adds to that potential. About 50 lava tubes and a few other types of caves ...
  • Corn, Carolyn A; Hiesey, William M (Island Ecosystems IRP, U.S. International Biological Program, 1973-02)
    Hawaiian Metrosideros distribution extends from tropical to cool-temperature climates throughout the six major islands of the Hawaiian Island chain. It forms a highly polymorphic complex that occurs in a continuous ...
  • Paik, Yong K; Sung, Kee C (Island Ecosystems IRP, U.S. International Biological Program Reports, 1973-02)
    Eighteen samples from twelve populations of Drosophila immigrans in the islands of Kauai, Oahu and Hawaii in the Hawaiian archipelago were analyzed for inversion polymorphism in 1125 females and 206 males. Three kinds of ...
  • Hardy, D Elmo; Delfinado, Mercedes D (Island Ecosystems IRP, U.S. International Biological Program, 1973-02)
    The flightless dolichopodid fly being described here was recovered from leaf litter samples collected in native forest on the island of Hawaii, at 5100 ft. on Saddle Road, 19°40132" N latitude and 155°20 130" E longitude ...
  • Spatz, Gunter (Island Ecosystems IRP, U.S. International Biological Program, 1973-02)
    Some environmental factors which influence the reproductive behavior of Acacia koa var. hawaiiensis (Rock) were studied on the east flank of Mauna Loa, Hawaii. Additionally, some factors were tested under controlled ...
  • Mueller-Dombois, Dieter (Island Ecosystems IRP, U.S. International Biological Program, 1973-03)
    The point is made that ecological principles generated from the study of continental ecosystems cannot be extrapolated to oceanic islands without reservations. Island ecosystems are not necessarily unique at the level of ...
