  • Structure and Seasonal Dynamics of the Fish Assemblage in the Cabrillo
           Beach Area of Los Angeles Harbor, California

    • Authors: Larry G. Allen et al.
      Abstract: Structure and seasonal dynamics of the fish assemblage in the Cabrillo Beach area of Los Angeles Harbor. California by Larry G. Allen, Michael H. Horn, Frank A. Edmands II, and Carol A. Usui, Bull. Southern California Acad. Sci., 82:47-70, 1983. Eggs, larvae, and juvenile-adult fishes were sampled monthly over a one-year period (February 1979-.Ianuary 1980) in the Cabrillo Beach area, a relatively little altered section of Los Angeles Harbor. Engraulis mordax was the most abundant species of juvenile-adult fish while sciaenid eggs and E. mordax larvae dominated the ichthyoplankton samples. Both the juvenile-adult and egg and larval populations showed marked seasonal fluctuations in abundance. Quantitative clustering of juvenile-adult species in each sample produced five distinct groups of resident and periodic species. Temperature and depth (of capture) accounted for 76% of the variation in juvenile-adult abundances based on two canonical correlation axes. The Cabrillo Beach area contains a variety of habitats and supports a seasonally dynamic fish fauna characterized by a high proportion of juveniles.

           Palaearctic Species in Southern California (Hymenoptera: CoUetidae)

    • Authors: Roy R. Snelling
      Abstract: Studies on North American bees of the genus Hylaeus. 6. An adventive Palaearctic species in Southern California (Hymenoptera: Colletidae). Roy R. Snelling. Bull. Southern California Acad. Sci., 82(1):12-16, 1983. Hylaeus (Spatulariella) punctatus (Brullé) is a common, widespread bee in the western Palaearctic Region, occurring in the countries bordering the Mediterranean Sea. This paper records H. punctatus from Playa del Rey, Los Angeles County, California; this is the first record for both the subgenus and species in the Western Hemisphere. Figures and descriptive notes are provided to aid in the separation of this bee from other North American species of Hylaeus.

  • Reproduction of Feral Goats on Santa Catalina Island, California

    • Authors: Bruce E. Coblentz
      Abstract: Reproduction of Feral Goats on Santa Catalina Island, California by Bruce E. Coblentz. Bull. Southern California Acad. Sci., 8 1(3): 128-1 37, 1982. Natality of feral goats on Santa Catalina Island appeared to be a density-dependent response to forage quality and quantity. Conception rates ranged from 1.11 corpora lutea/pregnancy in a poor forage area to 1.80 corpora lutea/pregnancy in a good forage area. Body weight, dressed weight, hind foot length, horn length, and kidney fat index of goats from the good forage area were significantly greater (P < 0.05) than those from the poor forage area. Partial control of goats on the island increased natality; total removal of feral goats was recommended.

  • Late Pleistocene Vertebrates from a Mormon Mountain Cave in Southern
           Nevada

    • Authors: George T. Jefferson
      Abstract: Late Pleistocene Vertebrates from a Morman Mountain Cave in Southern Nevada by George T. Jefferson, Bull. Southern California Acad. Sci., 81(3): 121-127, 1982. A mammalian assemblage of latest Pleistocene Early Recent age containing animals no longer living in southern Nevada has been recovered from a limestone cave on the north side of the Mormon Mountains, Lincoln County, Nevada, approximately 1 12 kilometers northeast of Las Vegas. The cave is developed in late Paleozoic limestones and lies at an elevation of approximately 1372 meters above sea level in an area which supports a pinyon-juniper, sagebrush floristic community. Some of the fossil species from the cave have modem representatives that presently live in this habitat. Other species, such as Ochotona princeps (pika), Marmota flaviventris (marmot), and Citellus lateralis (golden mantled ground squirrel) either do not now range into southern Nevada or are present only at the highest elevations in this region, in pine or fir forest at elevations about 2135 meters. The fossil occurrence of Ochotona, Marmota, and Citellus lateralis in southern Nevada is anomalous relative to their present distribution and suggests that pine and fir floras were at least 610 to 915 meters lower in elevation when these taxa were living in the area. Upward shifts of floristic communities in the Southwest have been attributed to the warming trend of post-Wisconsin climates over the past 8000 to 11 ,000 years. Changes in the distribution of small mammals in the Southwest have occurred in response to geographic shifts of floristic communities. The difference in elevation between the cave assemblage and Recent small mammal faunas of similar composition is compared to the difference in elevation between radiocarbon-dated fossil floras and Recent floras. These correlations provide an approximate minimum age of 8000 years before present for the assemblage.

  • New Records and New Species of the Genus Lebbeus (Caridea: Hippolytidae)
           in the Eastern Pacific Ocean

    • Authors: Mary K. Wicksten et al.
      Abstract: New records and new species of the genus Lebbeus (Caridea: Hippolytidae) in the eastern Pacific Ocean by Mary K. Wicksten and Matilde Méndez G., Bull. Southern California Acad. Sci., 81(3):106-120, 1982. Lebbeus scrippsi n. sp. and L. splendidus n. sp. are described from off the coasts of Peru and Chile. Lebbeus vicinus montereyensis n. subsp. is described from Monterey Bay, California and off western Mexico. Southern range extensions are given for L. grandimanus, L. lagunae. L. possjeticus, and L. zebra. Lebbeus brandti is reported for the first time in the eastern Pacific. We suggest that L. curvirostris Zarenkov may belong to the genus Nauticaris, and that L. bidentatus Zarenkov may be a southern race of L. washingtonianus (Rathbun). A key is presented for all the species of Lebbeus in the eastern Pacific.

      Abstract: A multivariate study of morphological variation of the limpet Notoacmea depicta (Hinds) and its synonyms Notoacmea gabatella (Berry) and Notoacmea lepisma (Berry) (Gastropoda: Acmaeidae) by David R. Lindberg, Bull. Southern California Acad. Sci., 8 1(2):87-96, 1982. Three nominal species of marine plant limpets from southern California are examined using discriminant function analysis. Two of the species, Notoacmea depicta and N. gabatella had been synonymized earlier based on radular morphology. The results of the discriminant analysis allow for the synonymization oi N. lepisma with N. depicta. The apertural variation seen in the 3 forms of N. depicta appears to be related to the intraspecific variation in the host plant Zostera marina. The oval form of N. depicta is reported and illustrated from Mugu Lagoon, Ventura County. This is a new northern locality record for this form and the first report of its occurrence on Z. marina.

  • Electrophoretic Evidence for Self-fertilization in Two Species of
           Spirorbid Polychaetes

    • Authors: Richard Beckwitt
      Abstract: Electrophoretic evidence for self-fertilization in two species of spirorbid polychaetes by Richard Beckwitt, Bull. Southern California Acad. Sci., 81(2):61-68, 1982. The inheritance of electrophoretically detectable enzymatic variation was studied by means of laboratory culture of Pileolaria pseudomilitaris and Janua brasiliensis. These variants are inherited as simple Mendelian codominants in single-pair matings. A small percentage of progeny from single-pair matings of each species are produced by self-fertilization in these hermaphroditic worms. Isolated individuals of P. pseudomilitaris produced reduced numbers of progeny with genotypes that confirmed self-fertilization by the parent. Isolated individuals of J. brasiliensis did not reproduce in culture. The high degree of polymorphism at several loci suggests that self-fertilization is not a common occurrence in natural populations.

  • Status of Sea Turtle Nesting in Southern Baja California, Mexico

    • Authors: Thomes H. Fritts et al.
      Abstract: Status of sea turtle nesting in southern Baja California. Mexico by Thomas H. Fritts, Margery L. Stinson, and Rene Marquez M. Bull. Southern California Acad. Sci., 81(2):51-60, 1982. A paucity of data on nesting by sea turtles on beaches in Baja California, México exists. Terrestrial and aerial surveys of coastal Baja California Sur between Punta Marques on the outer coast and La Paz on the gulf coast in August and September 1978, located nesting beaches presumably frequented by Lepidochelys olivacea. Successful oviposition by these turtles is apparently dependent upon beach configuration and recent rainfall patterns that affect the friability of the sand. A high percentage of open nest holes were found in sand too friable to maintain its shape during construction of nest chambers. Reports from local residents of southern Baja California suggest that leatherback turtles (Dermochelys coriacea) nest in southern Baja California from October through March. The carapace of a female leatherback killed while nesting near Cabo Falso substantiates oral reports of other nestings in 1976-1978.

  • Salt Marsh Algal Mat Composition: Spatial and Temporal Comparisons

    • Authors: Joy B. Zedler
      Abstract: Salt marsh algal mat composition: spatial and temporal comparisons by Joy B. Zedler, Bull. Southern California Acad. Sci., 81(1):41-50. Diatoms, filamentous algae, and green algae form thick algal mats on the soil surface of a southern California salt marsh. Algal composition in four habitats (including three elevations and four marsh vegetation types) differed both spatially and temporally during 1977. Of the most frequently occurring species (32 diatoms, 4 bluegreen algae, and 2 green algae). 37 were non-randomly distributed in space, and 36 were non-random in seasonal occurrence. Shifts in species composition, measured by similarity of the consecutive sampling periods, occurred in spring and fall, with bluegreen algae more frequent in warm seasons and diatoms and green algae more frequent in cool seasons.

      Abstract: Taxonomic status of some neotropical garter snakes (genus Thamnophis) by Robert G. Webb, Bull. Southern California Acad, of Sci. 81(1):26-40. Study of the black-necked garter snake, Thamnophis cyrtopsis, and of three other taxa of garter snakes from south of the Isthmus of Tehuantepec, Mexico, indicates that 1) T. cyrtopsis collaris (Jan) occurs in the Mexican state of Chiapas and in Guatemala, 2) T. cyrtopsis var. fulvus (Bocourt) is a valid species occurring in Chiapas, Guatemala, Honduras, and El Salvador, 3) T. sumichrasti cerebrosus Smith has been incorrectly referred to the species sumichrasti and cyrtopsis, and seems to have affinities with T. marcianiis, and 4) T. sumichrasti salvini Smith, Nixon and Smith is a synonym of T. cyrtopsis collaris.

      Abstract: The taxonomy of some neotropical Hylaeus and descriptions of new taxa (Hymenoptera: Colletidae) by Roy R. Snelling. Bull. Southern California Acad. Sci., 81(1): 1-25, 1982. All previously described Hylaeus from Mexico and Central America are placed within existing subgenera and some new synonymies are proposed. The following species are placed in the subgenus Prosopis: H. aztecus and H. transvittatus. Species placed in the subgenus Hylaeopsis are: H. callosulus (=H. callosa =H. monacha), H. dubiosus. H. gracillimus (=H. gracillinea). H. grossus (=H. maculata), H. gualanicus (=H. ruficollis =H. albifrontella), H. maculipennis, H. maculosus. H. mexicanus. H. opaciventris, H. subgriseus, H. titanius, H. vigilans (=H. trepandus) and H. zamoranicus. The following are assigned to the subgenus Hylaeana: H. costaricensis, H. knabi, H. panamensis (=H. aztecus of previous authors), H. quadratiferus, H. rufoclypeatus and H. trivittatus. Prosopis crenulata and P. howardiella. both described as hylaeines, are an andrenid and colletid, respectively. Four new species in the subgenus Hylaeana are described from Jamaica, French Guiana and Trinidad. A new subgenus is described to accommodate H. cruentus, H. orbicus and a new species from Bolivia.

  • Factors Affecting Germination of Chaparral Seeds

    • Authors: Jon E. Keeley
      Abstract: Factors affecting germination of chaparral seeds by Jon E. Keeley. Bull. Southern California Acad. Sci., 83(3): 1 13-120, 1984. Seedling establishment is uncommon under mature chaparral but abundant after fire. Germination from soils collected beneath chaparral and in an adjacent burned site were compared after various treatments. Application of an aqueous leachate from the dominant overstory shrub (Adenostoma fasciculatum) failed to produce any inhibition of seedling emergence from the mature chaparral soil but rather increased germination. Soil heating and powdered charred wood (charate) stimulated germination of dicots but not grasses. Tests of specific species showed Phacelia cicutaria and Salvia columbariae markedly stimulated by charate whereas Cryptantha muricata and Lotus salsuginosus were not. Grasses were abundant in the bum soil and germinated readily without treatment; their residence time in the soil, however, may be limited as they were uncommon in the mature chaparral soil. Light was a significant factor in germination of both monocots and dicots. Continuous darkness significantly reduced germination over a 12 hour photoperiod at ~230 μE m-2 s-1 or ~20 μE m-2 s-1 or periodic (several hours/ week) light of variable intensity.

      Abstract: Seasonal abundance of pinnipeds at San Nicolas Island, California, 1980-1982 by Brent S. Stewart and Pamela K. Yochem. Bull. Southern California Acad. Sci., 83(3):121-132, 1984. Seasonal cycles in abundance of northern elephant seals, California sea lions, harbor seals, and Guadalupe fur seals at San Nicolas Island, California, were monitored by frequent ground and aerial surveys from February 1980 through September 1982. Northern elephant seals were most abundant in late January and early February during the height of their breeding season and again in late April to early May when juveniles and adult females hauled out to molt. Sea lions were most abundant in late June to early July during the height of their breeding season and were least abundant in winter and early spring. Harbor seals were in greatest abundance in late May to early June when they were molting and numbers were lowest in winter. Guadalupe fur seals were present from June through September during their breeding season. Seasonal populations and pup production of elephant seals, sea lions, and .harbor seals increased each year.

      Abstract: The use of jackknife confidence intervals with the Richards Curve for describing avian growth patterns by David W. Bradley, Ross E. Landry, and Charles T. Collins. Bull. Southern California Acad. Sci., 83(3):133-147, 1984. A method is presented for measuring growth patterns in birds in which the Richards curve is used as a smoothing device for extracting convenient summary statistics from raw growth data. Jackknife confidence intervals for these statistics are developed and evaluated with Monte Carlo simulation. Strategies for making interspecific and intraspecific comparisons among populations are discussed for both longitudinal and cross-sectional sampling schemes with emphasis on the appropriate scope of inference from different levels of sampling.

      Abstract: Algal distributions and temperature: test of an hypothesis based on vegetative growth rates by Joan G. Stewart. Bull. Southern California Acad. Sci., 83(2):57-68, 1984. Vegetative growth rates were measured for five species of red algae in response to different water temperatures under laboratory conditions to consider whether the behavior of the plants might help explain the restriction of certain taxa to subtidal habitats off" southern California coasts. The thalli from which cultures were initiated were adult— i.e., of a size characteristic of collected non-juvenile specimens in natural populations. All thalli grew more rapidly at warmer temperatures (16°C or 20°C) than at 12°C indicating that these species are not segregated into colder or warmer habitats by direct effects of temperature on vegetative growth.

      Abstract: Nesting green sea turtles (Chelonia mydas) on Isla Clarión, Islas Revillagigedos, Mexico by Frank T. Awbrey, Stephen Leatherwood, Edward D. Mitchell, and William Rogers. Bull. Southern California Acad. Sci., 83(2):69-75, 1984. Locations of green sea turtle (Chelonia mydas) nests were mapped and their density determined during beach surveys of Bahia Sulfur, Isla Clarion, Islas Revillagigedos, Mexico, conducted 9-1 1 October 1976. Based on 80 nests less than one year old in six sample quadrats, nest density was estimated as 0.027/m2. One old nest contained 76 spent eggs. At two other nests 89 and 92 hatchings were counted as they emerged. Possible annual turtle productivity in suitable areas of West Beach, Bahia Sulfur is estimated as 2.4 hatchlings/m-. Predation of hatchlings by ravens, various fishes, and possibly bottlenose dolphins was observed. At least 1 3 female turtles visited the beach during the three days. Several copulating pairs were observed and photographed.

  • Paraliparis nassarum n. sp. (Pisces, Liparididae) from off Southern
           California with Description of Its Otoliths and Others from North-east
           Pacific Liparidids

    • Authors: David L. Stein et al.
      Abstract: Paraliparis nassarum n. sp. (Pisces, Liparididae) from off southern California with description of its otoliths and others from north-east Pacific liparidids by David L. Stein and John E. Fitch. Bull. Southern California Acad. Sci., 83(2):76-83, 1984. Paraliparis nassarum, a previously unknown species of liparidid fish, is described from specimens collected in sablefish traps on the continental slope off southern California. The new species is primarily distinguished from P. rosaceus, its most similar relative, by having sparser premaxillary teeth, mandibular teeth slanted anteriorly, fewer vertebrae, more pectoral fin rays, and more caudal fin rays. Sagittal otoliths of P. nassarum, P. rosaceus, Careproctus furcellus, C. attenuatus, C. melanurus, C. ovigerum, Acantholiparis opercularis, Lipariscus nanus, Nectoliparis pelagicus, Liparis liparis, and L. pulchellus are described. The ostium of the otoliths of A. opercularis, L. nanus, P. nassarum, and P. rosaceus is closed over to form a tube, an apparently unique character among fishes. The medial face of the otolith of C. ovigerum is concave, unlike the flat medial faces of the otoliths of the other 10 species. These significant differences in otolith morphology suggest that our present understanding of liparidid relationships is inadequate and that liparidid genera may need revision.

  • Additional Avian Records from the Miocene of Kern County, California with
           the Description of a New Species of Fulmar (Aves: Procellariidae)

    • Authors: Hildegarde Howard
      Abstract: Additional avian records from the Miocene of Kern County, California with the description of a new species of fulmar (Aves:Procellariidae) by Hildegarde Howard. Bull. Southern California Acad. Sci., 83(2):84-89, 1984. Previously unrecorded avian taxa from the middle Miocene Sharktooth Hill Bonebed in Kern County, California are listed: Fulmarus n. sp., Osteodontornis ?orri, Ciconiidae gen. and sp. to be determined, and Megapaloelodus sp. Fulmarus miocaenus n. sp. is described from a humerus representing a smaller species than F. hammeri, the only other Tertiary fulmar recorded from California. It is also smaller than humeri of Recent species of fulmars and is further distinguished therefrom by a better developed bicipital area and more distally placed ectepicondylar prominence.

  • Plant Succession and Species Diversity in the Marblehead Quarry, Ohio

    • Authors: Gerald P. Hannes et al.
      Abstract: Plant succession and species diversity in the Marblehead Quarry, Ohio by Gerald P. Hannes and Susan M. Hannes. Bull. Southern California Acad. Sci., 83(2):90-98, 1984. In three abandoned sites in the Marblehead Quarry, plant species diversity generally increases through time, especially when examined on a vegetation strata basis. The composite diversity value is highest in an intermediately aged community where there is a great degree of habitat heterogeneity due to shading and increased litter and humus content in the soil. Dominance-diversity curves are initially geometric in the earliest successional stage and approach lognormal in the intermediate. That the oldest site does not generally conform to the expected pattern of traditional plant succession is possibly due to a physical characteristic other than time which affects this site and not the other two.

  • Primary Production in Grays Harbor Estuary, Washington

    • Authors: Ronald M. Thom
      Abstract: Primary production in Grays Harbor estuary, Washington by Ronald M. Thorn. Bull. Southern California Acad. Sci., 83(2):99-105, 1984. An estimate of annual primary production in Grays Harbor estuary, Washington, is presented. Eelgrass contributed the largest proportion of organic carbon production followed by benthic algae, marsh phanerogams and phytoplankton. The relatively great contribution of benthic microalgae and eelgrass to total estuarine primary production can be explained by the extensive mudflats with and without eelgrass that exist in the seaward parts of the estuary and the high per unit area rates by plants in these habitats. Average annual total primary production in the estuary was estimated to be 2.6 x 105 kgC/km2, which is intermediate between published estimates for Chesapeake Bay (1.4 x 105 kgC/km2) and Nanaimo River estuary, British Columbia (6.8 x 105 kgC/km2).

  • Redescription of Janaria mirabilis, a Calcified Hydroid from the Eastern
           Pacific

    • Authors: Stephen D. Cairns et al.
      Abstract: Redescription of Janaria mirabilis, a calcified hydroid from the Eastern Pacific by Stephen D. Cairns and J. Laurens Barnard. Bull. Southern California Acad. Sci., 83(1): 1-11, 1984. Janaria mirabilis is redescribed and illustrated based on scanning electron microscopy (SEM) of the corallum, SEM of critical-point-dried decalcified specimens, and histology of decalcified specimens. Three types of gastrozooids are distinguished and the gonozooids were found to be superficial stalked structures, not ampullate as previously suggested. The resemblance of J. mirabilis to certain bryozoans is discussed and it is also compared to the other two Recent calcified hydractiniids now known. J. mirabilis is considered an important evolutionary link between the hydractiniid hydroids and the stylasterid hydrocorals in that both probably had a common ancestor in the Paleocene. The commonly occuring vesicles of J. mirabilis are hypothesized to be symbionts of some kind. Twenty new records of J. mirabilis, including 118 specimens, are reported, extending its distribution south to Panama.

      Abstract: Early twentieth century records of marine decapod crustaceans from Los Angeles and Orange counties, California by Mary K. Wicksten. Bull. Southern California Acad. Sci., 83(1): 12-42, 1984. During 1900-1930, 100 species of decapod crustaceans were collected along the coasts of Orange and Los Angeles counties, California. Records from the published literature, the files of the Allan Hancock Foundation, and the collections of the U.S. National Museum are presented. Checklists for major areas of collecting are provided. Thirty-four other species, not reported during 1900-1930, are listed.

  • Two Cretaceous Nautiloids from Baja California, Mexico, and Southern
           California

    • Authors: Frederick A. Sundberg
      Abstract: Two cretaceous nautiloids from Baja California, Mexico, and southern California by Frederick A. Sundberg. Bull. Southern California Acad. Sci., 83(1):43-52, 1984. Two genera of nautiloids not previously reported from the Western Hemisphere are present in the Cretaceous of Baja California, Mexico, and southern California. Eucymatoceras sp. is from the Alisitos Formation (Aptian-Albian) near Arroyo El Rosario. Anglonautilus catarinae n. sp. is from the Rosario Group (Maastrichtian) of Santa Catarina Landing, Baja California, and Carlsbad, California, and the Williams Formation (late Campanian to early Maastrichtian) of the Santa Ana Mountains, California.
