  • Marine Hydroid Assemblages in Soft-Bottom Habitats on the Hueneme Shelf
           off Southern California, and Factors Influencing Hydroid Distribution

    • Authors: Dennis C. Lees
      Abstract: Twenty-five marine hydroid species were encountered in studies on Hueneme Shelf. Fourteen species appear to occur primarily in areas of soft substrates. These species exhibited distinct patterns in depth distribution and specific substrate preference. Clytia bakeri and Phialella 'rugosa characterized the shallow region of the study area (3 to 11 m), Tubularia sp. A, Plumularia alicia, Hydrallmania distans, Aglaophenia dispar, Clytia universitatis, and Lovenella nodosa characterized the mid-depths (11 to 33 m), and Plumularia mobilis, Monobrachium parasitum, Thuiaria 'alba, Euphysa sp., Corymorpha palma, and Aglaophenia lophocarpa characterized the deeper region (24 to 60 m). These patterns were stable over several years. Factors probably operative in these distribution patterns include sediment stability, availability of substrates, and food. Favored substrates were polychaete worm tubes, shells, and shell debris. These observations constitute range extensions for eight of the species. Two species are probably undescribed. Natural history information is presented on all species.

  • Deep-Water Biological Assemblages of a Hard-Bottom Bank-Ridge Complex of
           the Southern California Continental Borderland

    • Authors: Andrew L. Lissner et al.
      Abstract: A manned submersible survey of Tanner and Cortes Banks and Santa Rosa-Cortes Ridge, offshore of southern California, U.S.A., was conducted to characterize the hard-bottom, biological assemblages from 14 m to approximately 150 m depth. Four major assemblages were observed; their dominant taxa were: 1) Eisenia arborea/erect coralline algae from at least 14 to 40 m; 2) Agarum fimbriatum/Laminaria farlowii from 40 to 60 m; 3) encrusting coralline algae from 60 to 90 m; and 4) Florometra serratissima/ ophiuroid from 90 to at least 150 m depth. Subdominate organisms in the shallow assemblage consisted of understory algae (reds and browns) and brittle stars; coralline algae, brown algae, gorgonians and seastars at mid-depth; and seastars, gorgonians and sponges at greater depths. The species and assemblages observed on the banks and ridge are very similar with those occurring in other hard-bottom areas adjacent to the southern California mainland and Channel Islands. However, the depth ranges for these assemblages and several of their species are much greater than observed elsewhere. An exception to this observation is the Florometra/ ophiuroid assemblage, which is quite common in some deeper- water (100 m to at least 300 m) areas of the Southern California Bight and the Santa Maria Basin. The increased depth ranges and high abundance of the bank assemblages appear to be influenced by water clarity, probably related to their isolation from coastal influences including runoff, the potential for a deep mixed layer caused by strong wave and surge activity, and the greater survey area compared with other studies.

  • Catastrophic Flooding and Distributional Patterns of Pacific Cordgrass
           (Spartina foliosa Trin.)

    • Authors: Joy B. Zedler
      Abstract: The distribution of Pacific cordgrass (Spartina foliosa Trin.) is patchy within the southern California region, within particular wetlands and within clones. Small-scale patchiness cannot be fully explained by environmental variables. However, study of cordgrass before and after catastrophic flooding has led to an alternative model. It is proposed that establishment is most likely after fresh water dilutes soil salinities and that expansion and persistence depend on previous densities, disturbances, and competitors. The lower intertidal marsh soils are nearly always hypersaline (35-45 ppt), and germination of cordgrass seed is rare. Reproduction is primarily by rhizomes and tillers. Soil salinity is reduced with episodic flooding, at which time cordgrass can establish seedlings and invade suitable habitats. Clones spread more rapidly after flooding. Within clones, densities increase after flooding in proportion to their pre-flood densities. Cordgrass is establishment limited, and historical events exert substantial control over its distribution and abundance.

  • Density, Distribution, and Feeding of the Marine Snail Norrisia norrisi
           (Mollusca: Gastropoda) on the Kelp Macrocystis pyrifera (Phaeophyta:
           Laminariales)

    • Authors: Timothy D. Stebbins
      Abstract: Grazing by the snail Norrisia norrisi on Macrocystis pyrifera was studied off Santa Catalina Island, California. Snails occurred on all parts of M. pyrifera plants and averaged 8.7 individuals/plant. Laboratory feeding experiments indicated that N. norrisi consumed significantly more sporophyll tissue (53%) than either mature (23%) or apical (24%) laminae. Snails consumed approximately 1-3% of the estimated daily M. pyrifera production. Consequently, grazing by these snails may not be significant under normal conditions. However, the strong preference for sporophyll tissue suggests that N. norrisi could have significant effects on the reproductive capacity of M. pyrifera, especially in kelp beds damaged by storms or other disturbances.

  • A New Species of Heptacarpus from California, with a Redescription of
           Heptacarpus palpator (Owen) (Caridea: Hippolytidae)

    • Authors: Mary K. Wicksten
      Abstract: A new species of Heptacarpus, a small shrimp marked with brown dots, is described. It ranges from Santa Rosa Island, California to Guadalupe Island, Mexico. Related to H. palpator and H. brevirostris, it can be distinguished from them by having only one large distal spine on the first segment of the antennular peduncle, and often having a spine at the distal end of the carpus of the first pereopod. Heptacarpus palpator is redescribed and better distinguished from H. brevirostris. Heptacarpus palpator ranges from Monterey Bay, California to the south, while H. brevirostris usually lives north of Monterey Bay.

  • Trace Element Composition of Obsidian Butte, Imperial County, California

    • Authors: Richard E. Hughes
      Abstract: Non-destructive energy dispersive x-ray fluorescence analyses were performed on rhyolitic volcanic glass (obsidian) from Obsidian Butte, located at the south end of the Salton Sea in Imperial County, California. Sixteen trace and rare earth element concentrations were measured in parts per million (ppm), and these values compared favorably with analyses employing destructive techniques. The results of the present study demonstrate that archaeological artifacts can be matched reliably to the Obsidian Butte source on the basis of non-destructive quantitative analysis, facilitating the study of prehistoric Southern California obsidian trade and interlaboratory comparison of analytical results.

  • The Taxonomic Status of Two North American Lithurge (Hymenoptera:
           Megachilidae)

    • Authors: Roy R. Snelling
      Abstract: Subsequent to my 1983 review of the North American species of Lithurge, the type specimen of L. planifrons (Friese) has been examined: it is a senior synonym of L. socorroensis (Mitchell) (NEW SYNONYMY). The species that I incorrectly believed to be L. planifrons is here described as L. bitorulosa, no prior name being available. A corrected key to the North American species is included.

  • Notes on Three European Land Mollusks Introduced to California

    • Authors: Barry Roth
      Abstract: Cecilioides acicula (Müller 1774) is newly recorded as an introduction in California. Pimctum conspectum (Bland 1865) is a synonym of Punctum (Toltecia) pusillum (Lowe 1831); widely distributed in western North America, it may be both native and introduced. Previous records in California of Arion circumscriptus Johnston. 1828, are shown to pertain to Arion (Carinarion) silvaticus Lohmander, 1937; the latest documented finding of the species in the state is 1949.
