  • The Reef Cornetfish, Fistularia commersonii Rüppell, 1838, New to the
           California Marine Fish Fauna

    • Authors: Milton S. Love
      Abstract: In 2015, there were two sightings of the reef cornetfish, Fistularia commersonii Rüppell, 1838, in southern California waters. These two individuals, observed at San Clemente Island and Laguna Beach, mark the first time this species has been reported from California waters.

  • Redescription of Bathygyge grandis Hansen, 1897 (Crustacea, Isopoda,
           Bopyridae) from Southern California with erection of a new subfamily,
           Bathygyginae, for it

    • Authors: John C. Markham
      Abstract: Abstract.—The bopyrid isopod species Bathygyge grandis Hansen, 1897, a reported parasite of several species of the genus Glyphocrangon (Caridea, family Glyphocrangonidae) worldwide, is fully described for the first time on the basis of material collected off the coast of southern California, the closest collection known to the type-locality of the species. Included are a complete synonymy and a discussion of the systematic position of the genus Bathygyge.

  • Seed Collection and Germination Strategies for Common Wetland and Coastal
           Sage Scrub Species in Southern California

    • Authors: Michelle L. Barton et al.
      Abstract: There is a need for a consolidated source of information on native vegetation seed collection and germination strategies in southern California. Published literature on these methods is often experimental, species-specific, and widely scattered throughout online and print media. Planting and restoration strategies may need to be site-specific; however, similar methodological approaches are often utilized allowing for the development of general strategies for seed collection, storage, and germination methods. A better understanding of species-specific seed attributes and growth processes will help restoration ecologists collect high-quality, viable seed, thereby increasing the potential success of the restored vegetation community by reducing plant mortality, project costs, and effort. This paper synthesizes seed collection and germination strategies for native vegetation common to southern California estuarine wetland, coastal dune, and coastal sage scrub systems.

  • Nudibranch Range Shifts associated with the 2014 Warm Anomaly in the
           Northeast Pacific

    • Authors: Jeffrey HR Goddard et al.
      Abstract: Abstract.—The Northeast Pacific Ocean was anomalously warm in 2014, despite ENSO-neutral conditions in the tropical Pacific. We documented northern range shifts associated with this anomaly for 30 species of nudibranchs and other shallow-water, benthic heterobranch gastropods from southern California to southern Oregon. Nine of these (Placida cremoniana, Trapania velox, Doriopsilla fulva, Janolus anulatus, J. barbarensis, Flabellina cooperi, Anteaeolidiella chromosoma, A. oliviae, and Noumeaella rubrofasciata) were recorded from new northernmost localities, while the remainder were found at or near northern range limits established mainly during past El Niño events. All 30 species have planktotrophic larval development, and six were observed spawning at northern localities, increasing the likelihood that their ranges will continue to shift poleward as the strong 2015-16 El Niño develops. Notable among these was Okenia rosacea, usually found south of San Francisco and last observed in Oregon as a single specimen found during the 1997-98 El Niño. In 2015 this bright pink nudibranch reached high densities and was observed spawning throughout northern California and into southern Oregon. Okenia rosacea is therefore poised to exploit abundant prey resources previously out of its reach in northern Oregon and Washington. Our results not only demonstrate a striking biological response to the 2014 warm anomaly in the North Pacific Ocean, but also support early physical indications of a larger regional climate shift, one reinforced by long-term global warming. Combined with historical data, these results highlight how shallow-water nudibranchs, with their planktotrophic larvae, short life cycles, conspicuous coloration, and accessibility are excellent biological indicators of ocean climate in the region.

  • The Return of the King of the Kelp Forest: Distribution, Abundance, and
           Biomass of Giant Sea Bass (Stereolepis gigas) off Santa Catalina Island,
           California, 2014-2015.

    • Authors: Parker H. House et al.
      Abstract: It is rare to find evidence of top predators recovering after being negatively affected by overfishing. However, recent findings suggest a nascent return of the critically endangered giant sea bass (Stereolepis gigas) to southern California. To provide the first population assessment of giant sea bass, surveys were conducted during the 2014/2015 summers off Santa Catalina Island, CA. Eight sites were surveyed on both the windward and leeward side of Santa Catalina Island every two weeks from June through August. Of the eight sites, three aggregations were identified at Goat Harbor, The V’s, and Little Harbor, CA. These three aggregation sites, the largest containing 24 individuals, contained a mean stock biomass of 19.6 kg/1000 m2 over both summers. Over the course of the both summers the giant sea bass population was primarily made up of 1.2 - 1.3 m TL individuals with several small and newly mature fish observed in aggregations. Comparison to historical data for the island suggests giant sea bass are recovering, but have not reached pre-exploitation levels.

  • The Lower Cambrian Olenellidae of the Southern Marble Mountains,
           California

    • Authors: Joseph F. Riccio
      Abstract: All morphological entities of the cephalon and thorax of the species studied herein indicate that the Olenellidae was probably a highly specialized family of trilobites. Loss of cephalic spines by resorption in which one pair may remain as the genal spines or two pairs remain as the genal and intergenal spines, is evident in specimens of the Olenellidae. The anterior course of the facial suture, even though fused, indicates that this family belongs to the order Opisthoparia. The hypostoma of Olenellus and Paedeumias, although distinct from each other, are of generic and not of specific value. Intergenal spines which occur in O. bristolensis and O. insolens are of generic importance even though they are aborted in early ontogenetic stages. In O. bristolensis, the size of the genal angle, position of the genal spines, and the glabellar ratio vary independently of each other whereas the size of the cephalon displays an orderly progression of growth. Trilobites studied herein do not molt in coordinate stages but molt in an orderly progression regardless of the size of the individual.
