Sacc. and Pycnoporus coccineus (Fr.) Bond. and Sing., syn. Coriolus sangutneus (L. ex Fr.) G. H. Cunn.; and against two brown-rot fungi, Lenzites trabea Pers. ex Fr. and Coniophora olivacea (Fr.) Karst. The species most resistant to decay were Palaquium hornei, Intsia bijuga, Fagraea gracilipes, Syzygium spp. complex, and Dacrydium elatum. Most of the species tested were highly susceptible to decay. There was a tendency, both among species and with in species, for the denser and less water-absorbent wood to be more resistant to decay. Also, the outer heartwood was, in general, more resistant to decay than inner heartwood.Item type: Item , Reversal of Ethionine Inhibition by Methionine during Slime Mold Development(University of Hawai'i Press, 1967-10) Hohl, Hans R.; Hamamoto, Susan T.Item type: Item , Revision of the Genus Pandanus Stickman, Part 25.

The majority of the Plotosidae are freshwater inhabitants, some of which are indigenous to both Australia and New Guinea. The marine members of the family and two freshwater members possess a dendritic organ. It is suggested that this organ has an osmoregulatory function.Item type: Item , Ecological Significance of a Drifting Object to Pelagic Fishes(University of Hawai'i Press, 1967-10) Gooding, Reginald M.; Magnuson, John J.Item type: Item , Bathymetric Distribution of Chaetognatha, Siphonophorae, Medusae, and Ctenophorae off San Diego, California(University of Hawai'i Press, 1967-10) Alvarino, AngelesItem type: Item , The Zoeal Stages and Glaucothoe of the Tropical Eastern Pacific Hermit Crab Trizopagurus magnificus (Bouvier, 1898) (Decapoda; Diogenidae), Reared in the Laboratory(University of Hawai'i Press, 1967-10) Provenzano, Anthony J J.R.Larvae were reared under various temperature conditions. Those maintained at 15°C were unable to moult to the second instar although some individuals lived as long as 35 days after hatching. At 20°C some individuals were able to reach fifth instar, but glaucothoes were obtained only at 25°C, 33-52 days after hatching. Effects of starvation and temperature on larval survival are discussed. The number of zoeal stages in the development of this species is variable, as it is in other diogenids which have been studied in the laboratory, glaucothoes of this species being obtained after four or five zoeal instars. Descriptions and illustrations of the zoeal stages and the glaucothoe are presented. No other larvae of this genus have been described and intra-generic comparisons of larval morphology were not possible, but a comparison was made of the zoeal and glaucothoe stages of this species with those of others in the family.Item type: Item , The Ecology of Pelagic Amphipoda, II: Observations on the Reproductive Cycles of Several Pelagic Amphipods from the Waters off Southern California(University of Hawai'i Press, 1967-10) Brusca, Gary J.Item type: Item , On the Surface Swarming of Euphausiid Crustaceans(University of Hawai'i Press, 1967-10) Komaki, YuzoA general aspect of the daytime surface swarming of Euphausia pacifica in Japanese nearshore waters is described in connection with the water temperature. Swarming usually starts with a local minimum temperature around 7°C and terminates with a temperature just below 16°C. The swarming season is essentially in spring, from February through May, with little difference among regions. The main swarming areas are on the Pacific coast around Kinkazan, and on the coast of the Sea of Japan around Sadogashima, in Wakasawan and its vicinity, around Oki, and on the east side of the Tsushima Gunto. It is shown that the swarming is closely related to cold water masses, and that the approach of offshore cold water masses to the nearshore areas and the mixing process in the coastal areas may provide favorable conditions for swarming . Swarming of E. pacifica is a phenomenon that occurs at the margins of the cold water bodies, and is related to the seasonal change in the geographical distribution of those euphausiids. A uniformly low water temperature profile must be the necessary condition for swarming, but other possible factors stimulating euphausiids to swarm are enumerated.Item type: Item , 21:4 Table of Contents - Pacific Science(University of Hawai'i Press, 1967-10)
