Part 36 The New Section Asperi from Indomalaya(University of Hawai'i Press, 1974-01) St. John, HaroldItem The Frequency of Vesicular-Arbuscular Mycorrhizae in the Roots of Camellia japonica L. from Different Sites in New Zealand(University of Hawai'i Press, 1974-01) Mejstrik, V.The development of short roots and the frequency of vesicular-arbuscular mycorrhizae in Camellia japonica L. were investigated in different localities in New Zealand. Mycorrhizal short roots were best developed at a depth of 5 to 15 cm. The average number of root hairs per centimeter of root length ranged from 80 to 120. The highest frequency of vesicular-arbuscular mycorrhizae was found in the short roots with diameters of 1.4 to 2.0 mm. Typical vesicular-arbuscular mycorrhizae were found in the short roots of Camellia japonica L. Spores of Endogone occurred in the rhizosphere of mycorrhizal roots.Item Evidence for the Elevation to Family Status of the Angelfishes (Pomacanthidae), Previously Considered to be a Subfamily of the Butterflyfish Family, Chaetodontidae(University of Hawai'i Press, 1974-01) Burgess, Warren E.Item The Barnacles of Fiji, with Observations on the Ecology of Barnacles on Tropical Shores(University of Hawai'i Press, 1974-01) Foster, B.A.Twenty species of barnacles are now known from Fiji as a result of recent collecting. The barnacle fauna has Malaysian affinities, but there are no endemic species. Brief descriptions and notes on habitats are given. The effects of erosion on the shell are described for the common intertidal species. The distribution patterns of the common intertidal species, except for those of the coral-boring barnacles, are described; and from these the influence of environmental factors on barnacle distribution is inferred. By determining upper lethal temperatures, recording a few environmental temperatures, and comparing these with similar information on temperate barnacles and shores, I have concluded that high temperatures could be a deterrent to the existence of large numbers of barnacles on sun-exposed surfaces of tropical shores. In shaded conditions barnacles can, however, occupy most of the available surface.Item Some Aspects of the Biology, Population Dynamics, and Functional Morphology of Musculista senhausia Benson (Bivalvia, Mytilidae)(University of Hawai'i Press, 1974-01) Morton, BrianItem Effects of Heated Effluent on Hermatypic Corals at Kahe Point, Oahu(University of Hawaii Press, 1974-01) Jokiel, Paul L.; Coles, Stephen L.The effect of thermal enrichment on hermatypic corals was investigated at Kahe Point, Oahu, Hawaii. The reef off the Kahe Power Plant was surveyed before and after an increase in thermal discharge that accompanied plant expansion. Abundances of dead and damaged corals correlated strongly with proximity to plant discharge and with levels of thermal enrichment. Nearly all corals in water 4° to 5° C above ambient were dead. In areas characterized by temperature increases from 2° to 4° C, the corals lost zooxanthellar pigment and suffered high mortality rates. Damage to the corals was most severe in late summer, and coincided with annual ambient temperature maxima. During the winter months the surviving corals slowly regained zooxanthellar pigment, but there was high mortality of corals during the recovery period. When generating capacity of the plant was increased from 270 to 360 megawatts, the area of dead and damaged corals increased from 0.38 hectare (0.94 acre) to 0.71 hectare (1.76 acre).Item 28:1 Table of Contents - Pacific Science(University of Hawai'i Press, 1974-01)
