ItemNovelties in Lipochaeta (Compositae). Hawaiian Plant Studies 119(University of Hawai'i Press, 1984-07)Included are descriptions, based on morphology, of 12 new species and three new varieties of Lipochaeta (Compositae) of the Hawaiian Islands.

ItemHawaii's Alectorioid Lichens(University of Hawai'i Press, 1984-07)Four species of alectorioid lichens are reported from Hawaii. Bryoria smithii (= Alectoria sandwicensis) is the most common. Two species, B. furcellata and Pseudephebe minuscula, are new records to the islands. The presence of B. lanestris is confirmed. Alectoria altaica and A. jubata are not present as previously reported. All species are confined to elevations above 2000 m on Maui and Hawaii. Their ecologies are discussed and a key to their identification is provided.

ItemFilamentous Fungal Populations of Hawaiian Beaches(University of Hawai'i Press, 1984-07)Heterotrophic micro-organisms were studied on three Hawaiian beaches-two of volcanic origin and one of carbonate. The volcanic beaches consisted of coarse particles with little organic matter. The carbonate beach consisted of coarse-to-fine, light-colored particles and contained more organic material than the volcanic sands. Fungi populations of the three beaches differed noticeably in their tolerance to temperature, salinity, and pH. In vitro testing of selected fungi showed wide tolerance to salinity levels, less tolerance to the high temperature of black sand, and no adaptation to alkaline pH levels. Heterotrophic microbe populations were greatest in the supratidal zone, except for the intertidal bacterial population of the black sand beach. In the subtidal black zone of the carbonate beach, only bacteria were well established, actinomycetes were absent, and fungi were few. Fifty percent of the fungi were common to any two of the three beaches. Zonal decrease in numbers at all three beaches was attributed to differences in submergence time.

ItemReproductive Cycle of the Pacific Bonito, Sarda chilensis (Scombridae), from Northern Chile(University of Hawai'i Press, 1984-07)The Pacific bonito, Sarda chilensis, spawns from spring to late summer off northern Chile. The smallest female in spawning condition was 410mm standard length (SL); the smallest spermiogenic male, 390mm SL. Females spawn more than one batch of eggs per season.
