The neogastropod family Columbellidae is a diverse cosmopolitan group of small marine snails, with its greatest diversity in the tropics. They are represented in high latitudes, but the columbellid fauna of higher latitudes tends to be much less well documented. The present paper documents the nearshore columbellid fauna of the northeastern Pacific Ocean, from the Aleutian Islands to Cedros Island, near the dividing point between Baja California and Baja California Sur. It is based on work by J.H. McLean, and completed posthumously. Examination of the regional columbellid collections in the Natural History Museum of Los Angeles County and the Santa Barbara Museum of Natural History has resulted in 24 species in eight genera, of which four new species and one new genus are described herein. The present paper focuses on dry shell material.

While preparing a review of the bivalve mollusk fauna of the Panamic Province, we encountered a conspicuous, colorful species of the genus Chama Linnaeus, 1758, that could not be identified with any named species. After examining type specimens at The Natural History Museum, London (BMNH), the United States National Museum of Natural History (USNM), the Academy of Natural Sciences, Philadelphia (ANSP), the California Academy of Sciences (CAS), the Natural History Museum of Los Angeles County (LACM), and the Santa Barbara Museum of Natural History (SBMNH), we have concluded that this species is new to science.

In 1973, George Lindsay, one of Baja California’s most eminent botanists, visited the islands of the Sea of Cortés together with Charles Lindbergh, Joseph Wood Krutch, and Kenneth Bechtel. Lindbergh, one of the most celebrated popular heroes of the twentieth century, had become by that time a committed conservationist, interested in the preservation of whales and in the conservation of nature at large. Joseph Wood Krutch, a naturalist, had written The Forgotten Peninsula, one of the first natural history descriptions of Baja California. George Lindsay had helped organize a series of scientific explorations into the Sea of Cortés and the peninsula of Baja California, first from the San Diego Natural History Museum, and later from the California Academy of Sciences (Banks 1962a,b; Lindsay 1962, 1964, 1966, 1970; Wiggins 1962). Kenneth Bechtel, a philanthropist from San Francisco, had given financial support to the Audubon Society in the 1950s and 1960s to study the sea bird rookery at Isla Rasa, which had been decreed a protected area by the Mexican government in 1962. Bechtel was interested in showing the Sea of Cortés to people who might be aroused by its astounding natural beauty and who might help to protect it. For this purpose, he organized the trip and invited Lindbergh to visit the region. The group flew a chartered Catalina flying-boat that allowed them to get to small and remote islands. They landed in the water and then piloted up to the beach so they could have shade under the wing. They visited many of the islands, starting from Consag north of Bahía de los Ángeles, and ending up in Espíritu Santo, east of the Bay of La Paz. It was a wonderful and memorable trip. Two or three months later, both Lindbergh and Lindsay traveled to Mexico City to watch the Mexican premiere of a documentary film on the Sea of Cortés by the California Academy of Sciences that Kenneth Bechtel had sponsored (see chap. 1). Taking advantage of the opportunity, and also of his immense popularity, Charles Lindbergh requested to see the president of Mexico, Luis Echeverría.

Recent revision of Cretaceous and Paleocene brachyurans in the collections of the Natural History Museum of Los Angeles County has revealed the presence of several new species. Based upon these fossils and their ages, it is evident that they played a pivotal role in the origination and subsequent dispersal of decapod crustaceans within the eastern North Pacific.

The newly-constructed Nature Gardens at the Natural History Museum of Los Angeles County (California, USA) were purposefully built to attract wildlife. In this study we wanted to find out to what extent this manufactured environment is successful in attracting native insect fauna to the urban core of the city when compared to the surrounding neighborhoods or natural areas on the periphery of Los Angeles. To determine this, a one-year Malaise trap catch from the Nature Gardens was compared with samples from four neighboring sites within a five-kilometer radius, as well as a site adjacent to natural habitat located sixteen kilometers away. Our analysis focused on the diversity and abundance of three pollinator groups: bees, flower flies and butterflies contrasted with a single non-pollinator group: scuttle flies.        Our findings show that the Nature Gardens support greater abundance and diversity than any of the nearby sites or the natural site for all pollinator taxa examined. In contrast, the natural site supported much higher abundance and diversity of the non-pollinator scuttle flies when compared to the Nature Gardens. Calculated evenness of all taxa was lower in the Nature Gardens than at the natural site and Shannon Diversity indices were highest in the Nature Gardens for flower flies and butterflies, but lower in the Nature Gardens than at the natural site for bees and scuttle flies. These results indicate that biodiversity in an urban environment can be selectively manipulated through management of green spaces, but may not duplicate the communities found in natural spaces. Rather, targeted management (through plantings, ground cover and other substrates, watering, pest management techniques, etc.) can increase fauna predictively to create a “wildlife spectacle” of charismatic microfauna.
