A New Species

Two small keyhole limpets (Mollusca: Gastropoda: Fissurellidae) were collected live by the senior author and his father (Charles Powell) in the winters of 1967 and 1968 from the side/bottom of moderately flat rocks in the low intertidal zone at Doheny Beach State Park, Dana Point, Orange County, southern California. The larger specimen was collected in the winter of 1968 and the small specimen was collected in winter of 1967. These specimens resemble the genus Lucapinella yet do not quite match any of the known species. The shells are also somewhat similar to Dendrofissurella scutellum from South Africa and two species of Amblychilepas from Australia, however neither of the Dohney Beach specimens can be attributed to those species. This possible new species is assigned to the genus Lucapinella and remains unnamed until additional specimens can be located to determine if they are a new species, a rare exotic species, or a very unusual, miniature L. callomarginata.

Bomb Attack

The Orange County or Three Californias trilogy offers radically different histories of Southern California in the mid twenty-first century. In The Wild Shore, the survivors of a neutron-bomb attack live like post-apocalyptic, pioneers, foraging among the ruins of destroyed California cities, while Tom Barnard, a survivor from the twentieth century, preserves his own vision of a pre-apocalyptic past, shot through with myths, tall tales, and quickly vanishing knowledge. The Gold Coast depicts a quasi-dystopian future of cheap, cookie-cutter condominiums and sprawling, triple-decker freeways. In trying to recover California’s socioecological history, Jim McPherson struggles, as a writer and an activist, to imagine how a more just and sustainable society might emerge. Pacific Edge envisions a utopian society that has transformed the landscape of Orange County by its commitment to social, economic, and environmental justice. In a solar and wind-powered future, the land is not a passive backdrop but an active force in Kevin Clairborne’s fight to sustain the principles and practices of socioeconomic justice.

SUMMARYTwo new species of Lepeophtheirus are described and illustrated based on a collection from the Orange County sewer outfall, California. They are: L. remiopsis sp.nov. from the branchial cavities and external body surfaces of Parophrys vetulus Girard, Hippoglossina stomata Eigenmann & Eigenmann, Pleuronichthys verticalis (Jordan & Gilbert), Chitonotus pugetensis (Steindachner), and Porichthys notatus (Girard); and L. rotundipes sp.nov. from the external body surfaces and occasionally the gill cavities of Scorpaena guttata (Girard) and Citharichthys stigmaeus Jordan & Gilbert.

Abstract Populations of the western spadefoot (Spea hammondii) in southern California occur in one of the most urbanized and fragmented landscapes on the planet and have lost up to 80% of their native habitat. Orange County is one of the last strongholds for this pond-breeding amphibian in the region, and ongoing restoration efforts targeting S. hammondii have involved habitat protection and the construction of artificial breeding ponds. These efforts have successfully increased breeding activity, but genetic characterization of the populations, including estimates of effective population size and admixture between the gene pools of constructed artificial and natural ponds, has never been undertaken. Using thousands of genome-wide single-nucleotide polymorphisms, we characterized the population structure, genetic diversity, and genetic connectivity of spadefoots in Orange County to guide ongoing and future management efforts. We identified at least two, and possibly three major genetic clusters, with additional substructure within clusters indicating that individual ponds are often genetically distinct. Estimates of landscape resistance suggest that ponds on either side of the Los Angeles Basin were likely interconnected historically but intense urban development has rendered them essentially isolated, and the resulting risk of interruption to natural metapopulation dynamics appears to be high. Resistance surfaces show that the existing artificial ponds were well-placed and connected to natural populations by low-resistance corridors. Toad samples from all ponds (natural and artificial) returned extremely low estimates of effective population size, possibly due to a bottleneck caused by a recent multi-year drought. Management efforts should focus on maintaining gene flow among natural and artificial ponds by both assisted migration and construction of new ponds to bolster the existing pond network in the region.

The earliest Lebanese in Southern California arrived around the turn of the twentieth century. Originally, they lived in an area east of downtown Los Angeles, still home to recent immigrants. Later, they moved west of downtown, as the location of their principal religious institutions shows us. Today's Lebanese are more widely scattered, with a substantial community in Orange County east of Los Angeles County. Most of the founders of the Lebanese Ladies Cultural Society live in or near Pasadena, an affluent city northeast of downtown Los Angeles.

Jane Smith had a family history of cancer and heart disease which made her very aware of the benefits of a healthy lifestyle. She discovered that there was no service offering pre-prepared healthy meals at home throughout Southern California. Smith has since decided to fill this market niche. She chose Orange County as the strategic location to serve the Southern California area. She opened headquarters in Irvine in January 1996. Jane's plan is to expand throughout California, promoting good health and great-tasting food. She also offers convenience by eliminating the need for shopping and cooking, while fueling the trend of home meal replacement.
