The weathering pattern and origin can account for differences in their fertility in the virgin state.Item type: Item , Foods of Rodents In the Hamakua District, Hawaii(University of Hawai'i Press, 1966-07) Kami, Harry T.The food habits of Rattus exulans, R. rattus, R. norvegicus, and Mus musculus captured in sugar cane fields, in gulches adjacent to cane fields, and in areas of human habitation, were determined from the stomach contents of 1205 rodents collected in 12 consecutive monthly samples. In cane fields the diet of R. exulans and R. rattus was primarily the internodes of sugar cane, while Mus fed principally on insects and grass seeds. In gulches R. exulans subsisted mainly on sugar cane, but R. rattus fed heavily on grass stalks and fruits. Mus from this habitat consumed kukui nuts and insects to a large extent, while the few R. norvegicus found here took a variety of foods. The foods of R. rattus and R. norvegicus captured near human habitations consisted mainly of garbage, other waste materials, and mixed livestock rations.Item type: Item , A New Camallanid Nematode from Hawaii(University of Hawai'i Press, 1966-07) Noble, Elmer R.Spirocamallanus istiblenni n. sp. is described from the intestine of Istiblennius zebra, a tidepool fish at Oahu, Hawaii. Female worms average 21.5 mm long, and the adult female:male length ratio is 1.44:1.0. The chief diagnostic characters include a reduced posterior ovary, a male caudal papillae pattern of six preanal and three postanal, a spicule length ratio of 3:2, and an H-shaped arrangement of the anterior excretory canal system. The buccal capsule possesses 13-14 spiral thickenings. The possible evolutionary significance of the posterior ovary is mentioned; a list of other parasites of this host and ecological consideration s are included.Item type: Item , Records of Asian and Western Pacific Marine Algae, Particularly Algae from Indonesia and the Philippines(University of Hawai'i Press, 1966-07) Taylor, W.R.Item type: Item , Observations on the Ecology of Four Apogonid Fishes(University of Hawai'i Press, 1966-07) Strasburg, Donald W.Item type: Item , An Annotated Bibliography on North Pacific Albatrosses(University of Hawai'i Press, 1966-07) Frings, Hubert; Frings, Mable; Frings, CarlItem type: Item , Magnetic Surveys Over the Hawaiian Islands and Their Geologic Implications(University of Hawai'i Press, 1966-07) Malahoff, Alexander; Woollard, G.P.A geophysical and geological analysis is made of a total field magnetic survey of the major islands of Hawaii. It is established that the regional distortion of the earth's normal magnetic field due to the topographic mass of the Hawaiian Ridge rising in places to over 30,000 ft above the ocean floor seldom exceeds 150 gammas. On each island, local magnetic anomalies having the form of lenticular and circular dipoles are found. The lenticular dipole anomalies appear to be related to crustal rifts that have been invaded by magmatic material of mantle origin , and the circular dipole anomalies are associated with primary areas of volcanic eruption. Although the inferred crustal rifts have surface geologic expression in some areas, such as the Koolau Mountains on Oahu, for the most part they do not. Furthermore, offshore magnetic data indicate that these features extend beyond the islands and out into the adjacent , deep-water , oceanic area where they can be traced for 100 miles or more. The most pronounced of these features is associated with the ocean floor Molokai Fracture Zone, which magnetically extends across the Hawaiian Ridge without interruption for an unknown distance to the west. The circular dipole anomalies appear to represent the effect of intrusions in volcanic pipes or vents rising from these crustal rifts which strike essentially east-west on the islands of Hawaii, Lanai, Maui, and Molokai, and west northwest-east southeast on Oahu, Kauai, and Niihau. With two exceptions, all of the anomalies indicate normal polarization conformable with the earth's present field.Item type: Item , 20:3 Table of Contents - Pacific Science(University of Hawai'i Press, 1966-07)
